R. China. Accepted 11 April, 2011 Livestock production and marketing have been driven by the growing consumer demand for high quality and low cost animal protein. As a result, intensive livestock industries have been rapidly developing globally. International trade, especially with China, creates new opportunities and challenges for the emerging international agriculture market. China provides an enormous market for international trade by stimulating its import and export activities. Pigs are the primary farm animals raised for human consumption in China, and the development of pork production systems in China will affect its trade globally. To meet the need for developing international animal agriculture and trade, this article describes the current status of the swine industry, its production in China and the factors that may affect its development. Urbanization, available farmland, grain production, water resources and management practices encompass some of these factors. In addition, the effects of the culture, religion and education of the populations on the development of swine sector in China are also discussed. Understanding the development of the swine production system and its associated factors is critical to assessing China’s impact and implication in the emerging international agricultural market. Key words: Animal agriculture, swine farm, pork production, international trade, China.

This practice was a meant to enhance farm productivity when farming area is limited. Here, in this paper, a brief review on the benefits of multiple cropping is presented focusing on the practices adopted by marginalized farmers, in general. In multiple cropping, it is generally argued that the practice favors an efficient utilization of resources like air, water, light, space, and nutrients by companion crops in both temporal and spatial dimensions due to their differential growth habits and seasonality. Multiple cropping could be one of the viable alternatives to cope uncertainties and changes, where food and nutritional uncertainty looming large. The ultimate outcome of multiple cropping could be visualized in adverse or harsh environment for increase agriculture production, livelihood and income. Various food products are obtained through multiple cropping. Land equivalent ratio (LER), relative yield total (RYT) and income equivalent ratio (IER) can be increased with mixed/intercropping systems.

  • INTRODUCTION the Use of Mixed Systems for Agricultural and Forestry Production Is by No Means New
    INTRODUCTION The use of mixed systems for agricultural and forestry production is by no means new. In pure agricultural systems the sowing of mixed annual crops has been a common farmer response to risk from climatic uncertainties to the need for diversity of food crops and to pragmatic observations of beneficial interactions between species. In the humid tropics, whether highland or lowland, sophisticated tree-crop mixtures have been developed over centuries using many species and where a wide variety of benefits are obtained. In the drier parts of Africa trees have formed important components of grazing systems, or have been left deliberately for their benefits in cultivated land. A simpler system, the use of agriculture crops for assisting in the establishment of forest plantations (taungya) is widespread, and in Africa as elsewhere shifting agriculture provided, in the past, a sustainable land-use system which is only now breaking down under the pressure of increasing populations. DEFINITIONS OF MIXED SYSTEMS OF PLANT PRODUCTION In practical terms this paper considers all multiple cropping systems, including agroforestry, agrisilviculture and taungya as 'mixed systems'. Multiple cropping includes all cropping patterns where more than one crop is grown on a piece of land in a year, and it may not be out of place to compare this with ICRAF's- definition of Agroforestry. Agroforestry is a collective name for land-use systems and technologies where woody perennials .. are deliberately used on the same land management unit as agricultural crops and/or animals in a spatial arrangement or in temporal sequence. In agroforestry systems there are both ecological and economic interactions between the different components.

  • Intensive Cropping- Sustainable Agriculture – IFS CROPPING PATTERN and CROPPING SYSTEM
    Cropping pattern and cropping system - Intensive cropping- Sustainable agriculture – IFS CROPPING PATTERN AND CROPPING SYSTEM Traditionally, increased food production has come from putting more land under cultivation. However, in large areas of the world, especially in Asia, all the land that can be economically cultivated is already in use. In future, most of the extra food needs must come from higher production from land already being farmed. A major share of this increase is likely to come from increasing the number of crops produced per year on a given land using improved crop cultivars. Such multiple cropping offers potential not only to increase food production but also land degradation. In India, the concept of cropping systems is as old as agriculture. Farmers preferred mixed cropping, especially under dry land conditions, to minimise the risk of total crop failure. Even in Vedas, there is a mention of first and second crops, indicating the existence of sequential cropping. A system is defined as a set of components that are interrelated and interact among themselves. A cropping system refers to a set of crop systems, making up the cropping activities of a farm system. Cropping system comprises all components required for the production of a particular crop and the interrelationships between them and environment (TAC, CGIAR, 1978). In other words, a cropping system usually refers to a combination of crops in time and space. Combination in time occurs when crops occupy different growing period and combinations in space occur when crops are inter planted. When annual crops are considered, a cropping system usually means the combination of crops within a given year (Willey et al., 1989 Cropping pattern The yearly sequence and spatial arrangement of crops or of crops and fallow on a given area.

This importance has resulted in a great interest to understand both the farmers’ perception of and adaptation to observed climate change. A good number of previous studies did explicitly focus on several adaptation strategies. Nevertheless, a better understanding of the socio-economic drivers underlying specific adaptive measures to climate change is crucial to inform specific adaptation components that will fall into a wider adaptation plan. In this respect, the present study focuses on the use of multiple cropping systems consisting of growing two or more crops on the same field either at the same time or one after another as climate change adaptation strategy. Accordingly, this paper examines different strategies commonly used to intensify agricultural production in tropical agriculture.

  • Globally Important Ingenious Agricultural Heritage Systems (GIAHS): Extent, Significance, and Implications for Development
    Globally Important Ingenious Agricultural Heritage Systems (GIAHS): extent, significance, and implications for development by Miguel A. Altieri University of California, Berkeley and Parviz Koohafkan Director, Rural Development Division Sustainable Development Department, FAO, Rome, Italy Introduction Agroecosystems cover more than one quarter of the global land area, reaching about 5 billion hectares. Agroecosystems are ecosystems in which people have deliberately selected crop plants and livestock animals to replace the natural flora and fauna. Highly simplified agroecosystems, (such as intensive cereal cropping, orchards and plantations, and intensive livestock raising), vary enormously in their intensity of human intervention, from those with only low-intensity management (e.g. shifting cultivation, home gardens, nomadic pastoralism, traditional farms, rotational fallows and savanna mixed farming), and from those of middle-intensity management (including multiple cropping, mixed horticulture, improved pasture mixed farming and alley farming). Five criteria can be used to classify agroecosystems in a region: (1) the types of crop and livestock; (2) the methods used to grow the crops (chemical or organic) and produce the livestock; (3) the relative intensity of use of labor, capital, and organization, and the resulting output of product; (4) the disposal of the products for consumption (whether used for subsistence or supplement on the farm or sold for cash or other goods); and (5) the structures used to facilitate fanning operations (Norman 1979). Based on these criteria, it is possible to recognize seven main types of agricultural systems in the world (Grigg 1974, also see Table 1 for a more detailed classification): 1. Shifting cultivation systems 2. Semipermanent rain-fed cropping systems 3.

In this respect, multiple cropping is an effective agricultural practice increasing the combined yield of crops and agricultural output. Over-cropping however, is a major cause of cultivated land degradation. The multiple cropping index (MCI) is an important parameter in arable farming systems. It reflects the utilization of water, soil, incoming radiation, as well as other natural resources. Hence, MCI monitoring is an important activity in the resources and food security assessment of agriculture. Therefore, the objective of this paper is to investigate the MCI monitoring method using multi-temporal moderate resolution imaging spectroradiometer (MODIS) normalized difference vegetation index (NDVI) data, for the time period of 2001 to 2004 in the study area of Southeastern China.

  • Upscaling the Adoption of Ecologically Sound Agriculture in the Philippines
    Proceedings of the Sixth International Permaculture Conference September-October 1996, Perth, Western Australia © Copyright Permaculture Association of Western Australia Inc. and authors. Upscaling the Adoption of Ecologically Sound Agriculture in the Philippines Teodoro C. Mendoza (Philippines) [Submitted Paper] Introduction Farmers abandoned their traditionally diversified farming systems in favor of monocropped systems characterized mainly by large usage of agrochemicals and high yielding varieties. In rice, the national average yields had increased. The key inputs in increasing lowland paddy rice yield were also adopted in the production of other major crops like corn, sugarcane, vegetables including fruit trees, and in a reforestation program better known as Industrial Tree Plantation (ITP). It took more than a decade before farmers began to realize the negative impacts of green revolu- tion. Farmers had noticed the deterioration of their living conditions (further indebt- edness, unable to send their children to school, declining stamina). Mostly, through the efforts of non-governmental organizations and organized farmer groups, the crit- icisms against high external input agriculture were ventilated. Non-governmental organizations started their own trials and experimentation on organic farming or chemical-free agriculture. They started establishing demonstration farms (NGO staff-managed and farmer organization-managed). Soon, conscience-stricken scientists/faculty members of the academe who were pre- viously trained as reductionist scientists started to listen and study the farmers’ complaints. A number of them have tried to validate and study the practical appli- cations of organic farming by some farmers. With the help of media (both print and broadcast), the popularization of the issues gained full speed and common knowledge.
