8 Agricultural Technology Transfer Project – Environmental Impact Assessment
Impact Analysis on Socioeconomic Environment in the Project Area
The implementation of cropping projects will produce many positive impacts on the project area, such as promoting socioeconomic development and industrial restructuring, raising land use efficiency in the project and surrounding areas, improving land resources use conditions, increasing farmers’ income, raising living standards of community residents, rationalizing distribution of social resources, etc.
Based on the analysis on the projects’ feasibility studies, Maps 4-1-1 to 4-1-5 and Table 1 of Annex 1, the implementation of all cropping projects will not change the nature of rural socioeconomic environment in the project area, but will improve agricultural conditions, improve and optimize the planting varieties, adjust planting structure, implement and disseminate agricultural technologies, etc. For example, Xinhuang Dong Nationality County Borneol Camphor Development Project, Changde Triploid Chinese White Poplar Project of Hunan, Qinba Mountainous Area Mulberry Fruit Project, Chunhua County Medicinal Herbs Project of Shaanxi will turn some degraded or secondary grassland, waste mudflat and unused land into land for forest, fruits and medicinal herbs with higher economic value. The changes in the land use still take place within the agricultural scope and will not produce unfavorable impacts on the socioeconomic environment in the project area.
The mode of “Company + Farmer Household” is adopted in most of the cropping project areas, under which the local ‘dragon-head’ enterprises take the lead to engage in industrial development, which is of some positive impacts on the economic restructuring, optimization of industrial structure and diversification of planting structure in the subproject and surrounding areas. The widespread application of agricultural technologies, especially in improved variety breeding and extension, plating, organic and green agricultural production and processing, balanced fertilizer applying and integrated pest management, etc. will raise production efficiency and product quality and at the same time, improve farmers’ technological knowledge and production skills, productive conditions and living environment, as a result, farmers’ income will be raised, which will effectively facilitate to improve the socioeconomic and environmental conditions in the subproject and surrounding areas. See case: Xinhuang Dong Nationality Autonomous County Borneol Camphor Development Project.
9 Agricultural Technology Transfer Project – Environmental Impact Assessment
Borneol Camphor Development Component, Xinhuang Dong Nationality Autonomous County
1. Construction Contents 1) Seedling Base: 2.8 ha of cutting seedling base is to be built in Aobeiluo Village of Fangjiatun Township; 28 ha of transplantation seedling base and 20 ha of cutting orchard are to be built at Tianlongtou, Miaochong, Bozhou and Mushanping Villages of Bozhou Town and Changle Village of Xinglong Town. 2) Borneol Camphor Raw Material Base: totaling an area of 466.67 ha, the base is to be built at Bozhou and Xinglong Towns on the either side of the Wushui River Basin along the National Highway 320 within the county. 3) Processing Base: six coarse camphor-processing plants are to be built in Bozhou and Xinglong Towns and the venue of intensive processing plant(s) is selected to be within the development zone of the Xinglongao Village of Dawanluo Township.
2. Construction Scale 1) Borneol Camphor Raw Material Base: producing 14,000 tons of branches and leaves per year. 2) Processing Base: extracting 35 tons of natural dextrorse borneol.
3. Construction Implications Xinhuang County is an economically underdeveloped minority nationality county located in the mountainous areas of western Hunan Province and is one of the 18 designated provincial poor counties of the Province. The total area of the county is 150,000 ha, of which mountainous areas are 126,700 ha, accounting for 84.1% of the total, with average per capita mountainous area of 0.56 ha, where the resources are rich and the soil and climate conditions are suitable for growing kapor. The implementation of the project can facilitate the use of rich land and Chinese herbal medicine resources in the local areas, promote agricultural restructuring in poor mountainous areas, and raise the income of poor households through applying the operational model of “company + farmer households (associations) + base”, and plays a major role in resolving the employment of the rural women and surplus labor force, developing the economy in nationality areas, increasing local financial and tax revenue, protecting ecological environment, ensuring sustainable agricultural development and maintaining rural social stability. Meanwhile, the project implementation can speed up the development of China’s natural borneol and promote the development of ‘green’ traditional Chinese medical industry.
4. Assessment Analysis The county administers 23 towns and townships, whose total population is 260,000, of which the Dong Minority Nationality population takes up 76%. The project area involves 50,600 villages from 613 village groups of 65 villages, 25,000 ha of mountainous area and 2,700 ha of cultivated land, of which paddy fields are 2,100 ha and dry land is 600 ha. The annual average per capita income of farmers is 1,470 yuan. The rich mountainous resources in the project area make it possible for disseminating the plantation of kapor. At present, the farmers are willing to plant borneol camphor tree since the net income per mu can amount to 800-1,000 yuan, 3-4 times over that of average crops. Presently, the industrialization of the plantation has not been shaped and the economic benefits are not obvious. After the completion of the project, scaled plantation can be achieved, which will improve the local ecological environment, and promote the development of ecological economic model at the local level. The project will absorb 5,000 seasonal workers, of which women account for 70%. Meanwhile, the income from the seedling and raw material bases can reach 11.22 million yuan, which will promote poverty reduction and accelerate economic development in minority nationality mountainous
Overall, cropping projects will be of favorable impacts on socioeconomic environment.

Current Status of and Impacts Assessment on Ecological Environment
Bio-safety Impact Analysis
It is an important aspect of environmental assessment whether there exists hidden biological safety peril with introducing, breeding and planting improved varieties. The degree of hidden bio-safety peril from introduction varies with different varieties and is decided by natural environmental conditions in the project and surrounding areas and by the surrounding sensitive areas and sensitive species. Most of the project activities will be implemented within the agricultural ecosystemthat is subject to high degree of artificial interference and there haven’t found any major sensitive areas and sensitive species within the system and surrounding areas, therefore, the impacts on bio-safety are minor.
Summary of Varieties to be Planted
There are total 39 cropping components under the Project, mainly involving planting of hybrid paddy, nuisance-free vegetables, melon, fruits and seedling. Most of the varieties have been planted and promoted in the local areas and the rest have been examined and approved by the National Cropping Varieties Examination and Approval Committee or the provinces. Details are described in Table 2 of Annex 1.
Biological Safety Impact Analysis
According to analysis, apart from the five areas of Xinhua County in Hunan Province (Borneol Camphor Development Project), Dongting Lake area (Triploid Chinese White Poplar Project) and Chaling County (Oil Tea Project) of Changde City, Zhouzhi County (Kiwi Fruit Project) and Chunhua County (Medicinal Herbs Breeding and Planting Project) of Shaanxi Province, all the other areas are artificial agricultural ecological systems majoring in farmlands, and there are no sensitive species and areas. Besides, the varieties or similar varieties have been planted in other areas under their respective system, and those introduced to the projects have been verified and approved by national or local authorities, or have been planted in the local areas for many years, therefore, project implementation will not bring about unfavorable impacts on the regional biological safety.
Around the proposed Changde Triploid Chinese White Poplar Project area, is mainly mountainous areas and lake-area agricultural ecological system, under which main crops include cotton and sugarcane. In view of the sensitivity of Dongting Lake area, biological safety analysis on triploid Chinese white poplar is indicated below:
16
Agricultural Technology Transfer Project – Environmental Impact Assessment
Triploid Chinese white poplar is very adapted to the environment in Dongting Lake area. It breeds and grows very fast and is of strong competitiveness. Will the plantation of the species under the proposed project affect the environment for the growth of other plants around the project area? Will it produce unfavorable impacts on the local biodiversity?
Triploid Chinese white poplar is a new variety through hybridization (backcross) of Chinese white poplar and Xinjiang poplar. During the process, the chromosome of triploid Chinese white poplar pollen is doubled and substituted. The birth of the poplar is a high-tech result of chromosome cell engineering, and is not a transgene result under which only a single shape is improved. Transgene technology cannot improve some harmful features of Chinese white poplar, such as seedling hardening in advance, leaf rust disease, leaf mottle, being prone to infection, cannot be rotated within five years, etc. Propagation of triploid Chinese white poplar is purely of vegetative type (relying on graft, cutting and rootcutting, etc.) and in its nucleus there are three chromosome groups, which are a barrier in meiotic reproduction, therefore, the triploid poplar, same as triploid watermelon, cannot form seeds. It excludes sexual process, therefore, there are no genefrequency changes, genetic drift or possibilities of unordered propagation. Furthermore, seedling is raised within the planned base, and therefore, it will not affect the population amount of other plants in the region.
Disease and insect damages of triploid poplar include angular leaf spot, longicorn, cutworm, etc. These disease and insects also damages the local poplars and introduced European and American poplar (black poplar). Triploid poplar will not introduce new diseases or insects, and it is of strong disease and insect resistance, therefore, it will not produce major impacts on the surrounding organisms.
Although the project areas of Chaling County of Hunan, Zhouzhi County and Chunhua Counties of Shaanxi have got mixed ecological system, forestland is basically artificial forest and most of the grassland is degraded or lies waste, and overall, these areas are still within the scope of agricultural ecological system. The introduced varieties have been planted in the local areas for many years. Chaling County is the home of oil tea; Zhouzhi County is a major kiwi fruit-planting county, “Haiwade” Kiwi Fruit has been planted for five years; Chunhua County is located at the gully areas of the Loess Plateau, mountain apricot, wild jujube, skullcap, senega and Chinese thorowax are average local varieties. In addition, there haven’t found any sensitive species and areas in the project and surrounding areas, therefore, project implementation will not bring about unfavorable impacts on regional bio-safety.
Although Xinhuang County Borneol Development Component area belongs to the ecosystemwhere mountainous area, dry land farming and forest are mixed, it used to be cultivated land. Two camphor trees containing dextrorse borneol were found at the county in 1988, based on which the borneol processing industry is developed. The area is the origin of kapor and therefore, component construction will not produce any adverse impacts on ecological safety.
Although the varieties to be introduced have not been decided for the Yintai Forest and Fruit Seedling Project and Yufeng Zhenxi Edible Fungus Development Project of Tongchuan City, they will be bred and planted within the allowable range of local
17
Agricultural Technology Transfer Project – Environmental Impact Assessment agricultural technological zone and respectively inside the greenhouses and fungus experimental rooms, and therefore, the biological safety of the introduced varieties can be easily controlled and they will not produce any harmful impacts on biological safety outside the system.
In summary, the introduction, breeding and planting of varieties under the cropping subproject will not result in any harmful impacts on the regional biological safety.
Landscape Ecology Analysis
Analysis on the Current Status of Landscape Ecology
Landscape ecology survey, conducted applying the theories and relevant research methodologies of landscape ecology, analyzes and compares from landscape perspective the macro structure, functions and human activities of the ecosystemin the project area. The purpose of the survey is to provide evidence for macro and integrated assessment of the project. According to the principles and approaches of landscape ecology categorizing, the four key elements of topography, vegetation, land-use status and modern geographical process in the project area are the evidence for dividing the basic landscape units.
Cropping subproject activities are distributed widely in 120 towns and townships from 60 counties of four project provinces while the planting area of each component is fairly small. From the macro perspective, most of the components are distributed in and belong to the farmland landscape category, and some are distributed in farmland-forest or farmland-grassland category. From a macro perspective, analysis assessment on the project will be conducted, applying a categorized analysis approach, according to the distribution of planting bases, relevant contents and features impacting the landscape, and landscape categories the project area falls under. Details are listed in Table 3 of Annex 1.
Landscape Ecology Impact Assessment
Sustainable Agricultural Technology and Capacity Building Project, Maoji County, Anhui Province focuses on dissemination and application of comprehensive modern agricultural technologies; Water Saving Technology Demonstration Component, Yangling, Shaanxi Province mainly demonstrates in sections drought-resistant seeds, water conservation agent, drought-resistant agent and new water saving equipment and technologies of different countries. Yufeng Edible Fungus Industrial Development Component, Heilongjiang Province breeds fungus inside the structures. These components will not change the original landscape structure and will not have any impact on landscape ecology.
18
Agricultural Technology Transfer Project – Environmental Impact Assessment
Nine projects will have some impact on landscape ecology, which is mainly increase in forestland spots, including Yuanjiang Citrus Project, Xinhuang Borneol Camphor Project, Changde Triploid Chinese White Poplar Project and Chaling County Oil Tea Proejct, Hunan Province, Apple Project Development Project, Baishui County, Zhouzhi County Organic Kiwi Fruit Project, Qinba Mountainous Area Mulberry Project, Qianyang Quality Fruit Tree Seedling Detoxification Project and Yangling Quality Fruits Planting Project. Most of the project areas are located at the hilly areas or gullies of the Loess Plateau, where farmland, grassland and forest alternate with each other. Although there are more forest spots, the size of them is small and they will not bring about obvious changes in the overall spatial structure of landscape. Furthermore, the increase in forest spots will be of positive impacts on ecological environment in these areas.
Regarding the Chunhua County Medicinal Herbs Breeding and Plating Project and the Medicinal Herbs GAP Production and Processing Project, most of the herbs plating bases are located at the gully areas of the Loess Plateau and the planted herbs include mountain apricot, wild jujube, Hippophae rhamnoides, and bi-annual and perennial herbs of skullcap, senega, Chinese thorowax, etc. As a result of project implementation, the vegetation in the area will be increased. The area of the two projects is fairly large, which is 1,780 ha and 784 ha respectively, therefore, project implementation will have major impacts on the regional landscape ecology, with remarkable increase of high-coverage artificial forest and grass landscape and remarkable decrease of farmland and degraded grass landscape. Higher coverage of forest and grass will effectively lower water and soil erosion in the area and improve regional ecological environment. Overall, project implementation will produce positive impacts on landscape ecology.
Apart from the above, the rest of the cropping projects will be of minor impacts on the landscape, which are originated from farmland modernization, such as construction of field paths, irrigation and drainage ditches, and protective belt and network, etc. They fragment the continuous farmland landscape to form many landscape galleries, which are conducive to improving agricultural production conditions. Their common features are that there are basically no changes to the original farmland landscape category while the changes only take place in plant types or varieties, for example, some projects focus on improving the original varieties, some turn grain crops to economic crops of melon, fruit and vegetable, etc., and some are built with facilities and greenhouses, etc. Although some of the projects are implemented by farmer households and there are some minor changes in the landscape, which, however, still belongs to the same type and will not produce harmful impacts on the overall regional ecological environment.
In summary, the impacts of cropping projects will be of minor or below minor impacts on landscape ecology while most of the impacts are positive and are conducive to improving ecological environment and ensuring agricultural production.

Analysis assessment on Soil Erosion
Analysis on the Current Status of Soil Erosion in the Project Area
Soil erosion status of cropping projects is indicated in Maps 4-2-1, 4-2-2, 4-2-3, 4-2-4.
In view of the distribution of soil erosion regions under the projects, there are 15 projects are distributed in the region without obvious erosion, 5 projects are in the region with slight water erosion, 9 projects are in the region with medium water erosion and 1 project in region with severe water erosion, 4 projects are in region with severe water erosion and slight wind erosion, 7 projects are in region with slight wind erosion and slight water erosion, 3 projects are in region with slight wind erosion. The location of projects in each of the soil erosion regions is listed in Table 4 of Annex 1.
Analysis on Impacts of Project Implementation on Soil Erosion
According to the contents and characters of the cropping projects, the elements impacting soil erosion are categorized as follows:
1) Project activities during construction, such as land leveling, building of drainage ditches, farmland paths, relevant facilities and houses, etc. will severely disturb surface vegetation and soil and will result in wind and water erosion and exacerbate soil erosion in the project area. Since project construction is conducted within the agricultural ecological system, the increased soil erosion only takes place during construction period and after construction is completed, soil erosion will be decreased. In addition, some of the activities include some soil erosion control contents, such as land leveling, lining of ditches, etc. Therefore, the impacts of project activities during construction on soil erosion are acceptable to the system, are minor on external systems and are thus acceptable in view of the environmental protection. 2) Cropping activities. Since the cropping methods are not changed totally, therefore, the activities will not produce negative impact on soil erosion. The cropping varieties of some projects will be changed, especially in vegetation type and vegetation coverage, such as the Xinhuang Borneol Camphor Development Project and Chaling County Oil Tea Project distributed in the region with slight water erosion. The implementation of these projects will increase forestland and grassland coverage in the project areas, reduce degraded land and low-coverage grassland and will thus reduce and mitigate water and soil erosion in the project areas. See case: Shaanxi Medicinal Herbs Breeding and Planting Project.

Agricultural Technology Transfer Project – Environmental Impact Assessment
Shaanxi Medicinal Herbs Breeding and Planting Project
1. Contents and Scale Setting up an improved-variety medicinal herbs breeding base with 750 mu, providing reliable improved seedling for large-scale planting of the herbs. Meanwhile, an efficient and standardized herbs planting base of 10,000 mu will be set up within the planting area and an extensive extraction and processing production line will be installed. Of the 10,000 mu, companies will take 1,000 mu and farmers will plant 8,000-9,000 mu.
2. Natural Environment Status The project is located at the Chewu Township, Chunhua County, Xianyang City, which is of Loess Plateau gully topography with highland, beams, ditches and gullies. The climate at the planting base is of temperate zone subhumid continental monsoon type, which is suitable for growth of various economic crops. Next to the project area is the Jing River system of the Wei River basin. The Heilu and loessal soil in the area is of poor fertility.
3. Socioeconomic Situation Chunhua is a poor county. The Longwu Village of Chewu Township is far off the beaten track, where there are no industries and agriculture is of conventional agricultural economic type. The project involves 1095 people from 273 households of 9 administrative villages. Population density is sparse, average per capita arable land is 5 mu, the grain crops are wheat and corn and the economic crops include mountain apricot, Hippophae rhamnoides and senega, etc. Average annual income per capita of the village is 520 yuan (lower than the county’s average) and average per capita grain is 196 jin (half a kilo).
4. Impacts on Soil Erosion Medicinal herbs planting is one of the agricultural activities. The main tasks of the project are to select and breed herbal varieties that are adaptable to the local natural, geographical and climate conditions and introduce new breeding technology of graft on top of the traditional planting methods, raise land use efficiency and increase farmers’ income. The roots of perennial medicinal herbs can conserve water and soil. The project area is located in semiarid area, where rainfall is low, groundwater distribution is complicated, topographical conditions are changeable and drinking and irrigation water mainly relies on rainwater and collected water. The project will invest 800,000 yuan in constructing water cellars, which will not only provide part of the drinking and irrigation water, but also prevent water and soil erosion to some degree. Terraces in the mountainous areas have served to improve land quality and also prevented water, soil and fertility from losing and is thus good for the environment.
The negative impacts of cropping projects on soil erosion only take place during construction period of ancillary facilities and are acceptable. Overall, most of the impacts are positive, especially the projects in hilly and mountainous areas and the Loess Plateau that are prone to water and soil erosion will have positive role in improving ecological environment and mitigating water and soil erosion in these areas.

Comprehensive Assessment on Impacts of Cropping Projects on Ecological Environment
Analysis assessment on ecological environment resulting from cropping projects is conducted according to the status of ecological environment in various project areas, after summarizing the above assessment results, integrating the ecological environmental protection and construction measures to be taken under the projects and considering the major construction stages and characters of various components.
According to matrix analysis on ecological impacts, the impacts of surface disturbances as a result of construction of structures during implementation on vegetation and soil are long term and irreversible. Soil erosion during construction period will produce negative impact, which, however, will be short time and take place in only a few areas, and is acceptable.
The negative impacts of cropping projects will be within the controllable range and can be mitigated through some measures. Therefore, the project will play a positive role in improving the ecological environment in the project area, and is thus feasible.
Impacts Analysis on Environment Quality
Brief Description of Current Status of Environment Quality
Cropping projects mainly involve the production of quality agricultural products, non- polluted vegetables, the construction of quality economic forest and fruits breeding and planting bases. Project objectives and contents have set up fairly high requirements on environmental quality, which, therefore, has become a basic condition and element for selecting project area.
According to the analysis on the environmental status of various project and surrounding areas, there are no environmental sensitive areas 500 meters around the project area;
Impacts Analysis on Environment Quality
Impacts of cropping projects on environmental quality are analyzed from two aspects: one is impact of cropping part (including construction of cropping bases) on environmental quality; the other is impact of processing part on environmental quality.
Impacts of Cropping Part on Environmental Quality
26
Agricultural Technology Transfer Project – Environmental Impact Assessment
The impacts are divided to two types: one is the various activities concerning the construction of cropping bases, including land leveling, construction of roads, cannels and relevant facilities. These activities will produce dust, vehicle exhaust, equipment noise, construction and living wastes, which will bring about short-term or instantaneous impacts on air, sound and water environment in the project area. However, the degree of impacts is limited and there are no targets extremely sensitive to the impacts in the project and surrounding areas, therefore, the impacts can be lowered to the acceptable level provided construction management is strengthened and construction work is standardized. The other is the surface source pollution originated from application of chemical fertilizers and pesticides within the cropping process. A series of technologies including balanced fertilizer application, integrated pest management, organic and non- polluted production, etc will be adopted in the cropping projects, and there will be significant changes in the selecting of pesticide and fertilizer varieties and application amount comparing with the conventional use of chemical fertilizers and pesticides, therefore, project implementation will effectively mitigate environmental pollution.
The application amount of pesticides and chemical fertilizers will be increased in the areas of Xinhuang Borneol Camphor Development Project in Hunan, Mulberry Fruit Project and Medicinal Herbs Breeding and Planting Project in Shaanxi. However, modern agricultural technologies will be adopted, pesticide and chemical fertilizer varieties will be selected and the amount will be applied according to the non-pollution production standards. In addition, these projects can raise water and soil conservation capacity in the project areas. Therefore, their environmental impacts are minor.
Use of Non-polluted Pesticides
Non-polluted pesticides refer to carefully selected biorational pesticides that are of effective preventive results on harmful organisms, but are biologically safe to human and livestock and other non-targeted organisms, are easily degraded under natural conditions, and will not produce obvious impacts on environmental quality. Non-polluted pesticides are set to five types including mineral, animal-source, microorganism, plant and non- polluted synthetic chemical pesticides. Non-polluted pesticides are mainly used on production of non-polluted fruits and vegetables.
Pest under the project will be controlled applying non-polluted synthetic chemical pesticides on the basis of biological pest disinfestation technology. Farmers are a key factor in the use of pesticides, who should be properly trained in advance on chemical pest management during critical periods and on critical targets. Meanwhile, fruit products associations should strengthen guidance and monitoring on pesticides application. Details are provided in “Methods on Pest Monitoring and Control” of the project provinces. The

Impacts of Processing Part on Environmental Quality
Of the 39 cropping projects, 28 have got processing contents, most of which deal with primary processing, such as seed processing, vegetable and fruit separation, etc. Their pollution on the environment is minor and can meet the standards for environmental functional districts and pollution charge after necessary protection measures are taken. Additional three processing projects including Yiyang Citrus Project, Chaling County Oil Tea Project and Xinhuang County Borneol Camphor Project will discharge some pollutants, producing some pollution on air, water and sound environment. Environmental protection measures should be strengthened for these projects and environmental assessment should be properly done in accordance with local environmental protection authorities. Detailed impacts of processing activities out of the cropping projects on environmental quality are described in Table 5 of Annex 1.
Conclusion
The 39 cropping projects under the Project will play a positive role in social and economic development and industrial restructuring, raising land resources use rate, increasing farmers’ income and improving living standards of community residents from the project and surrounding areas and will produce favorable impacts on social and economic environment. z The project areas belong to agricultural ecosystemmajoring in farmland with high degree of artificial interference, within which there are no important sensitive species and areas; the introduced varieties are basically those approved by national and local authorities, or have been planted in the localities for many years. Therefore, project implementation will not produce harmful impacts on regional bio-safety. z The original landscape structure has not been changed under most of the cropping projects, thus implementation of them will not produce any impacts on the landscape ecology. Forest and grassland coverage will be increased under some projects, resulting in minor impacts on landscape ecology. Furthermore, most of the impacts are favorable and are good for improving ecological environment and ensuring agricultural production. z Negative impacts on soil erosion will mainly take place during construction of ancillary facilities, but the impacts are acceptable. As a whole, the cropping projects will produce positive impacts on soil erosion, which will play a positive role in improving ecological environment and slowing down water and soil erosion in the project areas. z Overall, negative impacts on ecological environment will only take place during the construction period and within a limited scope and are thus acceptable. z The projects will improve regional ecological environment and unfavorable impacts can controlled within the limited scope and can be mitigated through some measures, therefore, in view of environmental protection, the Project is feasible.
32
Agricultural Technology Transfer Project – Environmental Impact Assessment z Most of the processing projects deal with primary processing. Their pollution on the environment is minor and can meet the standards for environmental functional districts and pollution charge after necessary protection measures are taken. A few processing projects will discharge some pollutants, producing some pollution on air, water and sound environment. Environmental protection measures should be strengthened for these projects and environmental assessment should be properly done in accordance with local environmental protection authorities.
Countermeasures and Suggestions
1) Ensuring that comprehensive modern agricultural production technologies are carried out in during project implementation, such as for improved varieties breeding, balanced fertilizer application, integrated pest management and organic agricultural production, etc., which will effectively reduce environmental impacts. 2) Strengthening project management and supervision and conducting environmental survey and monitoring on a regular basis according to plan. 3) Stepping up construction management during the construction period. Site mounds should be cleared and transported in a time manner and those not move away should be sprayed with water and covered to control dust. Access roads should be kept clean. Balance should be achieved in soil excavation and backfill to reduce construction spoil and extra spoil should be placed in low-lying sections and filled with soil. Sludge from channel dredging is prohibited for random placement, so as to avoid new water erosion that may block the channels again. Noise Standards at the Boundaries of Construction Sites should be strictly enforced, avoiding construction at night. When roads are renovated, rational route should be selected and foundation construction should avoid rainy season, so as to reduce water and soil erosion. Meanwhile, wastes from road construction should be cleaned in time and should be abandoned into water bodies to avoid water pollution. Production and living garbage should be treated separately, and corruptible substances should be composted. 4) Setting up files for registration and management of introduced varieties, timely monitoring changes in the environment in and around the new varieties planting areas; applying various comprehensive physical measures in pest management to create environmental conditions against the pests and for the breeding of various natural enemies and lower damages resulted from pests. Developing management procedures s to prohibit or restrict the use of pesticides in the project area; developing operational procedures on integrated pest management technologies; establishing technical center for integrated pest management; correctly and timely releasing to farmers the prediction and forecast on pest and grass disasters; integrating prediction and forecast, pesticide supply, and time frame for pest management. Setting up archiving system for pest and chemical pesticides application management to conduct effective monitoring over the application of chemical pesticides, and the use of nationally banned pesticides and those with high residues should be prohibited.
33
Agricultural Technology Transfer Project – Environmental Impact Assessment
5) Making the soil nutrients balanced soil test, nutrient analysis and balanced application of fertilizer to lower the initial amount of poisonous and harmful organisms and improve the self-resistance of plants. Applying mainly organic fertilizers supplemented with other fertilizers. Reasonably deciding fertilizer types, amount, the ratio between base and dressing fertilizers, and the dressing times and effect according to fertilizer demand rules of seedling, soil fertilizer supply characters and fertilizer effect. Organic farm fertilizer should be sufficiently aged and safely treated to kill pest ovum and weed seeds. Microelement fertilizers should be reasonably used. Apart from boron fertilizer, other microelement fertilizers should be applied through foliar dressing. 6) Selecting safe, low-poison and low-residue herbicides according to the varieties, distribution, damage, community structure and migrant trends of weeds to control weed damages. 7) Expanding the area of protection forest to raise forest coverage, adjust climate conditions, improve ecological environment and effectively bring water and soil erosion under control. For processing projects, afforestation should be carried out within plant compound. 8) Environmental protection department should be set up and full-time/part-time environmental management staff be arranged within the implementing agencies. The department and staff are responsible for enforcing laws and regulations on environmental protection, monitoring the changes in water, air and soil environmental quality within the project area, dealing with and reporting to the upper levels environmental issues and arranging for training on environmental protection know- how. 9) During project construction, local environmental protection agencies should be entrusted to conduct regular monitoring and supervision over noise and air pollution from construction activities. During the operational period, the major surface water sources, smoke and dust from boilers and air quality should be monitored on a regular basis and issues/problems be addressed in a timely manner. 10) Implementing agencies for Yuanjiang City Citrus Project, Chaling County Oil Tea Project and Xinhuang County Borneol Camphor Development Project of Hunan Province should keep close contacts with and report to the local environmental protection agencies regarding the status of their respective project, conduct their separate environmental impact assessment (EA) and take corresponding environmental protection measures in accordance with the requirements in the approval of the EA.

Water consumption includes drinking water for livestock and poultry and domestic water. Livestock and drinking water and wastewater production coefficient are indicated in Table 5-2-1, which are calculated under dung dry cleaning conditions. Water consumption and sewerage amount from breeding projects are listed in Table 5-2-2.

Breeding industry, especially milk cow breeding, consumes large amount of water. Breeding projects consume 1049×104m3/a, of which concentrated farms consume 16%,
36
Agricultural Technology Transfer Project – Environmental Impact Assessment separated farms/individual households consume 83.6%; sewerage amount is 197×104m3/a, 18.8% of total water consumption. However, the project agencies have attached great importance to water saving, applying multiple water saving and dung dry cleaning techniques, such as automatic drinker and milking machine, program-controlled cleaning system, recycled use of cleaning agent and dung dry cleaning, etc. As a result, breeding industry water consumption will be reduced by a large margin.
Pollution Sources
Originated from breeding projects, pollution sources refer to solid wastes, urine discharged by livestock and poultry of various farms, sewerage from cleaning pens and breeding compounds and apparatus and odor. z Solid waste sources: average solid wastes including dung, materials spread on pigsties, cowsheds and chicken coops, etc., fodder leftovers and scattered fur and feather, and dangerous solid wastes of corpses of livestock and poultry died of diseases; z Wastewater: sewerage from washing dung and cleaning apparatus and urine; z Odorous gases: irritant gases from dung and urine discharged by livestock and birds; z Microorganism pollution: anthrax, bird’s flu, brucellosis and TB, etc.; z Other pollutions: heavy metal pollution, livestock medication residue pollution, biological invasion from introduction of varieties, etc.;
Environmental impacts from livestock and poultry breeding are summarized in Table 5-2- 3 and environmental condition of a milk cow farm is shown in Figure 5-1.
Pollution Source Strength and Amount of Pollutants
The amount of pollutants produced by livestock and poultry relates not only to their varieties, but also to dung cleaning methods. The amount of dung, urine and major pollutants from the farms is normally worked out applying unit coefficient of dung and urine produced. The captioned coefficient is listed in Table 5-2-4.

The above table indicates that the discharged dung contains harmful gases of NH3 and H2S, and the concentration of which will be doubled if the dung is not cleaned on time or not treated promptly after cleaning. The odorous gases of methyl mercaptan, dimethyl disulfide ether and dimethylamine not only adversely affect the growth of livestock and birds, but also harm the health of nearby residents. However, dung dry cleaning will be adopted under these projects, dung will be promptly treated, as a result, the of source strength of harmful gases discharges will be lowered or reduced.
Environmental Impacts Analysis
Environmental impact analysis on the processing projects is described in Table 5-3-1.
Predictive Analysis on Socioeconomic Environmental Impacts
The development mode of “company + household” or “company + association + household” will be adopted in most of the 26 breeding projects. The objectives of them are to popularize, disseminate and apply the advanced agricultural technology projects and promote transfer of scientific and technological results through applying advanced biological and engineering technologies to produce provenance products, training on farmer households, technical services and standardized production.
Agricultural service systems should be improved through project implementation to form a technical services network under which farmer households will be trained before production, integrated technical guidance and advice provided during production and products be purchased after production.

Analysis on Ecological Environmental Impacts
Feed resources include stems and leaves of trees and shrubs, herbal plants of pastures, straws of crops, organic wastes from agro processing and concentrated feed needing to be supplemented, etc. Sufficient feed resources are the basis for development of breeding industry. However, it will affect the stability of local ecosystemif mainly relying on feed resources of natural forests and pastures. For example, overgrazing in Inner Mongolia exhausted pasture resources and resulted in land desertification and degradation.
Although breeding projects involve many varieties including cattle, sheep/goat, pig, chicken, duck and goose, etc., they have got two common characters:
1) Feed is mainly straws of crops and artificial herbage. The project provinces of Shaanxi, Anhui, Heilongjiang and Hunan are China’s agriculturally development areas with sufficient straw resources. Estimates show straw usage in these areas is only 50- 60%, and there have great development potentials. Abundant straw resources ensure the development of breeding industry. Grass will be mowed by sections, leaving high stubbles, which will reduce damages to soil structure and prevent water and soil erosion, and further maintain stability of the ecological system. 2) No matter scaled farms or household breeding, livestock and poultry will be kept in pens, which will avoid adverse impacts on the ecosystemfrom overgrazing.
Impacts on Agricultural Ecosystem
Analysis on Ecological Agriculture
Breeding is only an element of ecological agriculture. After being used by breeding industry, crops and straws can serve to develop animal husbandry, produce meat, egg and milk and achieve smooth cycle of the ecological agricultural system. The excrement after treatment is quality organic fertilizer. The conversion of pig, cattle and chicken manure to chemical fertilizer is listed in Table 5-3-2. Table 5-3-2: Conversion of Pig, Cattle and Chicken Manure to Chemical Fertilizer

5.3.2.2. Improving Soil Structure and Agricultural Ecological Environment
In recent years, with the improvement in intensification levels of breeding industry and extensive use of chemical fertilizers, the good practice of livestock and poultry dung being returned to farmland has been abandoned by the people, which has not only resulted in more serious environmental problems, but also led to soil structural damages and poor product quality due to improper use of chemical fertilizers. Livestock and poultry dung
52
Agricultural Technology Transfer Project – Environmental Impact Assessment can be dehydrated, fermented and deodorized to become quality complex organic fertilizer, which, comparing with chemical fertilizer, has got more complete nutrients, longer efficiency and is easier to be absorbed by crops, and is good for raising crop yield and quality and improving soil quality, and is disease resistant. Dung has got abundant nutrients, including organic substances, nitrogen, phosphorous, potassium and multiple microelements, which can serve to promote the breeding of soil microorganisms, improve soil structure and raise soil fertility, thus increasing crop yield and stabilizing the structure and functions of soil ecological system.
Impact Analysis on Biodiversity and Bio-safety
After a new exotic species is introduced to a new environment, if long-term experimental and observation work is not done, once uncontrolled straggling happens, it will result in serious destructions to the original biodiversity and bio-safety. The problems on bio-safety from improper species introduction have been attracted great attention from relevant government authorities.
There are 21 breeding components under the Project involving the introduction and breeding of improved varieties. Seen from the current status, new varieties are introduced through the following channels: z Stock seeds of improved varieties introduced from abroad or other area of China (the varieties already introduced to other areas and there are no new varieties to be introduced to the Project from foreign countries this time); z Improved varieties researched within China, such as the results of the 863 Plan; z Protection and optimization of local improved varieties;
In view of the above channels, the introduced varieties are the old ones introduced to China before and have been raised and bred in China for many years, and so far, no bio- safety problems have been found. Comparing with the past introduction, the introduction this time will not constitute threat to biodiversity and bio-safety in the introduced areas. All of the varieties introduced from within China have been improved, and there are no transgenic types; some of the varieties, such as the Qinchuan improved beef cattle, are improved based on the local varieties. Therefore, they will not threat local biodiversity and bio-safety either.
Impact Analysis on Water Environment
Waster pollution load is heavy from livestock and poultry breeding. The population equivalent of annual pollution load (in BOD5) from one chicken, one pig and one cattle is 0.5-0.7 people, 10-13 people and 30-35 people respectively. The pollution load of a ten- thousand-pig farm is equivalent to that of 100,000 to 130,000 people. Although sewerage amount from large and medium-sized livestock and poultry farms is not big, the pollution load is heavy.
Random discharge of wastewater from breeding farms will pollute surface and groundwater. The flow of wastewater into channels and ditches, pits and ponds, rivers and lakes will impact the aquatic ecosystem, making water black, odorous and eutrophicated, and further impacting landscape and water quality. Direct discharge of wastewater will also pollute shallow groundwater in the following aspects: first, nitrate and chlorine ion
53
Agricultural Technology Transfer Project – Environmental Impact Assessment pollute groundwater. Nitrogen in dung and urine enters soil in the three modes of hydrogen nitride, amide and nitrate, which will eventually become nitrate after being transformed by microorganisms. Nitrate is easily migrated with water and is apt to pollute groundwater. Second, biological pollution, which refers to that pathogenic microorganisms and parasite ovum are able to live and breed in soil for a long time.
Among the six categories of breeding components under the Project, milk cow breeding produces the largest amount of wastewater, followed by beef cattle breeding. The adoption of dry dung cleaning technique consumes 40-50% less water than average water cleaning of dung and the concentration of main pollutants is to be reduced by 6-10 times. Pollution will be reduced remarkably and water consumption lowered at factory pig farms due to the adoption of artificial dry dung cleaning technique, supplemented with water cleaning method. Dry cleaning of dung has been adopted and good effect been achieved at many of the pig farms in Hubei, Beijing and others. Little amount of wastewater (urine) is produced from goat, chicken, duck and goose breeding. Separated/scattered breeding households produce very little amount of wastewater due to their small scale.
Except for a few breeding projects that discharge wastewater to surface water bodies, wastewater from most of them is treated through biogas generating pits, oxidation ponds, aerobic and anaerobic treatment and is used as fertilizer, and thus they will not produce pollution to surface water environment. Wastewater from Milk Cow Embryo Transplant Project, Lianyuan City Beef Cattle Breeding Project and Zhenghong Pig Production Project of Hunan Province is discharged after aerobic and anaerobic treatment. According to environmental impact analysis, wastewater discharged to surface water bodies is diluted, producing very little pollution on surface water environment.
Anti-seepage structure has been set up for livestock and birds’ pens, wastewater treatment and storage facilities and wastewater will not be penetrated to and pollute groundwater. Concentration of pollutants in the discharged wastewater after treatment has been lowered remarkably; for the part used as fertilizer, if properly applied, it will produce minor impact on groundwater since organic substances will be absorbed and resolved by soil. However, for sandy soil with strong seepage, wastewater may pollute shallow groundwater. In this case, reasonable wastewater irrigation plan needs to be worked out and quality of groundwater in and around the project areas should be closely monitored.
Impacts Analysis on Anaerobic Environment
Impact Analysis on Odor from Breeding Industry
Odor mainly comes from pens, oxidation ponds and dung transportation and treatment, which includes inorganic gases of NH3 H2S and organic gases of methyl mercaptan and secaline, etc. Normally, the amount of odor is large and concentration is high under anaerobic conditions. The sequence of degree of odor impact on the environment is chicken > milk cow > pig > goat. Average concentration of odorous substances from cow/beef cattle breeding at different distance is indicated in Table 5-3-3.
54
Agricultural Technology Transfer Project – Environmental Impact Assessment
Table 5-3-3: Average Concentration of Odorous Substances at Different Distances. Unit: Mg/m3 Distance m Odor 5m 10m 20m 40m 80m
NH3 0.46 0.37 0.35 0.34 0.25 -3 -3 -3 CH3-SH 1.58×10 0.01 5.94×10 0.00 1.56×10 -3 -3 -3 -3 H2S 0.01 1.81×10 3.72×10 2.59×10 3.03×10 -3 -3 -3 (CH3)2N2 2.49×10 1.04×10 1.94×10 0.00 0.00
For a cow/cattle farm, under normal circumstances when the distance is around 5 meters, the concentration can reach the standard set in Odorous Pollutants Discharge Standards (GB14554-93). However, for a pig or chicken farm, the concentration at the points 20 meters away from the pigsties/chicken coops is dozens or even a hundred times over the standard. To mitigate odor impacts, the venues of scaled farms should be selected to be at least 500 meters away from and at downwind of the residential areas, and other controlling measures be taken.
For scattered breeding households, odorous pollution is normally minor due to their small scale. However, they should strengthen management and treatment of manure and take measures to control odor to reduce pollution source strength.
Impact Analysis on Smoke from Boilers
Heilongjiang and Shaanxi Provinces need boilers in winter for livestock and birds’ breeding or existence of spawns. Survey data from Heilongjiang shows that boiler tonnage at farms is normally small at around 1 ton/hour. To effectively control pollution, environment friendly coal-burning boilers should be used. According to assessment by Heilongjiang Provincial Institute of Environmental Protection, smoke and SO2 discharge concentration can meet the requirements of Category II region at time interval II in Boiler Environmental Air Pollutants Discharge Standards. Petroleum or natural gas boilers are used at a few farms; as a result, the smoke pollution is much slighter. In general, boiler smoke pollution on the environment is fairly minor.
Impacts Analysis on Noise Environment
Noise of a farm is originated from the yelling of livestock and birds. Normally, a farm would take up a large area and is over 500 meters away from the residential areas, and noise at its boundaries can meet the standard at daytime, producing minor impacts on residential blocks.
The amount of livestock and poultry raised by households is normally small; they are raised in pens, are active mostly at daytime and their yelling frequency is low. Therefore, the impacts on residential areas are minor.
55
Agricultural Technology Transfer Project – Environmental Impact Assessment
Impacts Analysis on Solid Wastes
Solid wastes include dung, spreading materials at pens, fodder leftovers, falling fur and feather and slag from boilers, etc. Dung is of most serious environmental impact. It contains abundant organic substances and large amount of elements needed for the growth of crops, such as nitrogen, phosphorous and potassium, etc.
Dung disposal methods under the Project mainly include compost, complex organic fertilizer processing, and fertilizer processing at biogas generating pits, etc. Manure after treatment is good organic fertilizer, which is of great significance in improving soil fertility and soil structure and sustaining soil productivity. Under normal circumstances, treated manure can be absorbed by soil and will not constitute environmental threat.
Boiler slag can be used to build roads and as material for house construction and will not pollute the environment.
Dead livestock and poultry need to be burned or buried according to requirements stipulated in the Technical Specifications for Pollution Control with Livestock and Poultry Breeding Industry, to avoid spread of diseases.
Impacts Analysis on People’s Health
Inside the intensified farms, the number of livestock is large, intensity is high, oxygen demand is big within the microenvironment, the concentration of CO2 discharged by livestock and poultry is high, and there are microorganism and dung pollutions. If the houses are promptly cleaned and dung and urine properly treated, the impacts on the health of workers will be greatly mitigated.
The impacts on the health of people outside the farms are mainly that diseases are spread through air, dung, soil and drinking water sources. The farms under the project are normally 500 meters away from the residential areas, and thus the possibilities of diseases being spread through air and impacting the health of residents are minor. It is required that dung and urine should be aged and treated aerobically and anaerobically, wastewater can only be reused when pathogenic bacteria and pollutants reach the set standards, meanwhile, the project venue should be selected to avoid water sources.
Livestock and poultry died of diseases will be disposed of through burning and safe burying, to avoid the spread of diseases. For those died of epidemic diseases, especially animal-human diseases, once found, the “Emergency Preparedness Plan for Control of Animal Epidemics should be activated and livestock and poultry should be slaughtered, safely buried or burned, so as to alleviate threat on the health of the people.
Environmental Impacts Mitigation Measures and Control Countermeasures for Breeding Components
Pollution Control Countermeasures for Selecting Venue of Breeding Farm
Livestock and poultry farms are prohibited to set up in the following areas:
56
Agricultural Technology Transfer Project – Environmental Impact Assessment
1) Domestic drinking water source protection area, scenic spots, the core and buffer areas of natural reserves; 2) Residential areas of cities and towns, including educational, scientific research areas, medical, commercial, industrial and sightseeing areas; 3) The forbidden areas set by county governments according to laws and regulations; 4) Other areas, designated by the state and according to law and regulation stipulations, need to be specially protected.
The venues of farms to be set up, renovated and expanded should be selected to avoid the above areas. When the venues are close to the forbidden areas, they should be on the prevailing downwind of these areas, and farm boundaries should not be less than 500 meters away from the captioned areas.
Countermeasures for Promoting Clean Production and Water Saving and Pollution Mitigation
Pollution control of livestock and poultry breeding should be managed from the source and through the breeding process. Reasonable feed, advanced dung cleaning techniques and standardized management should be adopted to improve usage of breeding resources, save water and eventually reduce pollution discharge.
1) Developing Environment Friendly and Ecological Feed
Feed should be rationally prescribed, such as the ideal protein type of prescription, to improve the efficiency in the absorption of protein and other nutrients. Active materials such as microorganism preparation, enzyme preparation and abstracted fluid from plants should be used so as to reduce discharge of pollutants and odorous substances.
2) Promoting Dung Dry Cleaning Technique
Dung cleaning techniques include dry cleaning, washing and soaking, which are technique good for saving water, reducing pollution discharge, maintaining manure quality and reducing the losses of nitrogen and phosphorous. The Project is to promote and disseminate the technique as the major measure for pollution control under each of the breeding projects. Wastewater quality and amount of different techniques are listed in Table 5-4-1. Table 5-4-1: Wastewater Quality and Amount at Pig Farms Applying Different Techniques of Dung Cleaning Washing Soaking Dry Cleaning Technique Technique Average Per 35~40 20~25 10~15 Water Pig L/d Consumption 10,000-pig 210~240 120~150 60~90 Farm m3/d BOD5 5000~6000 4000~10000 400~800 Water Quality CODcr 11000~13000 8000~24000 1000~2000 SS 17000~20000 28000~35000 100~340
57
Agricultural Technology Transfer Project – Environmental Impact Assessment
Seen from the above table, dung dry cleaning technique is superior over the washing and soaking techniques in both water consumption and wastewater quality.
Dung dry cleaning technique should be applied in all of the breeding projects. Through taking prompt and effective measures, dung should be cleaned separating from urine and wastewater, and dung sludge should be timely transported to storage or disposal sites.
Pollution Control Countermeasures for Storage of Livestock and Poultry Dung
1) Exclusive dung storage facilities should be set up at livestock and poultry farms, whose odor and pollutants’ emissions should be in tally with Discharge Standards of Pollutants from Livestock and Poultry Breeding Industry; 2) The location of storage facilities should be far (no less than 400 meters) from the various functional surface water bodies and should be set up the prevailing downwind of the production and living areas of the farms; 3) Anti-seepage measures should be taken for the storage facilities to prevent dung from polluting groundwater; 4) For farms with both cropping and breeding activities, the capacity of the storage facilities should be greater than the total dung produced within the maximum interval for applying fertilizer on crops; 5) Water/rainwater-proof installations should be set up for the storage facilities.
Pollution Control Countermeasures for Treatment and Utilization of Livestock and Poultry Dung
Methods of Livestock and Poultry Dung Treatment
Dung treatment measures have been proposed under the various breeding projects in accordance with local environmental conditions, which include composting, production of organic fertilizers, building biogas generating pits, and making use of biological energy, etc. These measures have been proven successful within China, the basic idea of which is to conduct treatment on dung and wastewater and use them as solid and liquid fertilizers, and therefore, they have been advocated by the State Environmental Protection Agency as ‘a method integrating environmental and ecological protection’.
1) Compost Method
The compost method is a simple and feasible method for dung treatment. Dung can be composted after adding a little carbon sources (straws and feed leftover) since its carbon/nitrogen content is low. Under normal circumstances, ratio of carbon and nitrogen is 30-35:1 and water content is 60-65% for raw materials. The buttress piled up is normally 2-3 meters in width, 1.5-2.0 meters in height and the length is not restricted. The aging period is normally between 30 to 35 days. Carbon/nitrogen ratio of the aged compost should be less than 20:1 and organic ingredients should be more than 35%. Rainproof shelters should be set up at the compost and storage compounds. Dung can be used only after treatment and reaching Non-pollution Sanitary Standards for Manure. This method is normally suitable for the dry and little-rainfall northern areas.
2) Method of Producing Organic and Complex Fertilizers
58
Agricultural Technology Transfer Project – Environmental Impact Assessment
The raw materials for producing organic and complex fertilizers are dung of poultry (chicken, duck and goose), livestock (pig, goat/sheep and cow/cattle), straws, cake dregs, and wastes from agro processing, etc.
The production techniques include pre-treatment of raw materials, inoculation of microorganisms, fermentation, dewatering, grinding, separation, packaging and measurement, etc. The specific methods vary with different raw materials and products.
Key technical points: among the raw materials, carbon/nitrogen proportion is better at 30- 35%, that of organic substances at 50-70% and that of water at around 50%. The technique flow chart for production of organic and complex fertilizers is listed below:
Coal Burning Air Heater
Wet Manure Lifting Storage Feeding Drying Cooling Fermenting Hopper Down Additives
