Four organization levels of biodiversity are often recognized: genetic diversity, species diversity, ecosystem diversity and landscape diversity. Landscape diversity refers to the spatial arrangement patterns of different patches, corridors and matrix elements. Ecosystem diversity refers to the structural arrangements of different primary producers, secondary producers and decomposers, including plants, animals and microorganisms with their environmental

  • Capital Formation and Agriculture Development in China Jikun Huang
    Capital Formation and Agriculture Development in China Jikun Huang Center for Chinese Agricultural Policy Chinese Academy of Sciences And Hengyun Ma College of Economics and Management Henan Agricultural University A Report Submitted to FAO, Rome August 2010 Capital Formation and Agriculture Development in China 1. Introduction In the post World War II era, modern development economists mostly agree that the role of agriculture and rural development is absolutely an integral part to process of nation building and healthy development (Johnston and Mellor, 1961; Johnston, 1970). Agriculture plays five important roles in the development of an economy: i) supplying high quality labor to factories, constructions sites and the service sector; ii) producing low cost food which will keep wages down for workers in the industrial sector; iii) producing fiber and other crops that can be inputs to production in other parts of the economy; iv) supplying commodities that can be exported and earn foreign exchange which can help finance imports of key technology packages and capital equipment; v) raising rural incomes. The view toward agricultural and rural development in the modern world has changed dramatically in the past several decades. Traditionally, agriculture was thought of an inferior partner in development. Since the size of the sector falls during development, it was logically considered that it could be ignored. Why is that leaders would ever want to invest in a sector that is shrinking? Some academics urged policy makers to treat agriculture like a black box from which resources could be costlessly extracted (Lewis, 1954). All investment was supposed to be targeted at the industry and the cities.

  • Water Efficient Irrigation and Environmentally Sustainable Irrigated Rice Production in China
    WATER EFFICIENT IRRIGATION AND ENVIRONMENTALLY SUSTAINABLE IRRIGATED RICE PRODUCTION IN CHINA Mao Zhi Professor, Department of Irrigation and Drainage, Wuhan University, Wuhan, 430072, P.R.China ABSTRACT Rice is one of the most important food crops contributing over 39% of the total food grain production in China. Out of 113 million hectares of area sown under food crops 28% is covered by rice. The traditional irrigation regime for rice, termed as “continuous deep flooding irrigation” was applied in China before 1970s. A tremendous amount of water was used for the rice growing and only a low yield of rice was obtained under this regime. Since 1980s, the industry water supply, urban and rural domestic water consumption have been increasing continuously. The shortage of water resources became an important problem and many water efficient irrigation regimes for rice have been tested, advanced, applied and spread in different regions of China. Based on the results of experiment and the experience of spread of these new irrigation regimes, the following three main kinds of water efficient irrigation regimes were found to be contributing to the sustainable increased water productivity viz. (1) combining shallow water depth with wetting and drying, (2)alternate wetting and drying and (3) semi-dry cultivation. In this paper, the standard of controlling field water, conditions and the attention points of the application for the three regimes are introduced and explained.. The causes of sustainable increase in water productivity and the environmental impacts by adopting these regimes are analyzed and discussed. 1. INTRODUCTION China is a major rice producing country having about 31 million ha under rice paddy cultivation.

Received: 2 April 2018; Accepted: 18 April 2018; Published: 21 April 2018 Abstract: Sustainable food production and food security are always challenging issues in China. This paper constructs a multi-element two-level constant-elasticity-of-substitution (CES) model to assess technological progress in, and its contribution to, japonica rice production in China. The results show that the speed of technological progress in the production of japonica rice on average was 0.44% per annum in 1985–2013, and technological progress has contributed significantly to the growth of japonica rice production in China. Robustness checks show that the results appear to be sensitive to which sub-sample is used. Labour and some other inputs are found to be significant but negative, especially during the middle sampling period of 1994–2006 and in eastern and western regions. This has important policy implications on the impact of rural-to-urban migration and farmers’ human development. Keywords: China’s food policy; sustainable food security system; japonica rice production; two-level CES function; technological progress 1.

  • The Future of Rural Income and Rice Production in China
    > ASEF/Alliance The future of rural income and rice production in China Land allocation for the rice farm Economic growth in China’s agricultural sector lags behind growth in industry and services, creating an ever widening rural-urban income gap. Yet growth beyond the farm offers new opportunities for farmers in China’s more advanced provinces: markets for new crops and increasing farm size. At present, the dual government objectives of increasing rural incomes and increasing rice production are clearly in conflict. Farmers can obtain incomes comparable to non-farm wages only when they stop rice cultivation and switch to more profitable crops. Otherwise, mechanization is necessary to allow large enough increases in farm size to raise household income and maintain national rice production levels.

Assessing the impacts of temperature variations on rice yield in China Abstract: Using a unique county-level panel on single-season rice yield and daily weather outcomes from 1996 to 2009, we examined the impacts of temperature variations on rice yield in China. We have five key findings: (i) in contrast to nearly all previous studies focusing on rice production in tropical/subtropical regions, we discovered that higher daily minimum temperature during the vegetative stage increased rice yield; (ii) consistent with previous assessments, we found that increased daily maximum temperature during the vegetative and ripening stages reduced rice yield; (iii) the impacts of solar radiation and rainfall on rice yield differed across the plant’s growth stages; (iv) estimated weather effects on yield differed by rice variety; and (v) weather variations caused a net economic loss of $21.6-88.2 million during the sample period, depending on model specifications and econometric estimation strategies.
