The rapid increase in the proportion of cash crops and livestock production in the Yangtze River Basin has led to commensurate increases in fertilizer and pesticide inputs. Excessive application of chemical fertilizer, organophosphorus pesticides and inappropriate disposal of agricultural waste induced water pollution and potentially threaten Agriculture Green Development(AGD). To ensure food security and the food supply capacity of the Yangtze River Basin, it is important to balance green and development, while ensuring the quality of water bodies. Multiple pollutants affect the transfer, adsorption, photolysis and degradation of each other throughout the soil-plant-water system. This paper considers the impact of multi-pollutants on the nitrogen and phosphorus cycles especially for crops, which are related to achieving food security and AGD. It presents prospective on theory, modeling and multi-pollutant control in the Yangtze River Basin for AGD that are of potential value for other developing regions.

Recent researches have primarily focused on the relationship between livelihood strategies and livelihood capital,with few empirical studies on the sensitivity of livelihood strategies to livestock production and marketization in Inner Mongolia Autonomous Region of *** study used an income distribution approach to categorize livelihood strategies of the respondents(n=394)into three types,i.e.,herder livelihood strategy(LS1),petty-herder livelihood strategy(LS2),and non-herder livelihood strategy(LS3).Using the multinomial logistic regression model,we compared livestock production and marketization across the three livelihood *** findings showed that(1)livestock production and marketization tended to favor LS1;(2)an increase in the land asset(contracted and rented grassland)and off-take rate increased the probability of households choosing LS1;(3)stocking rate was higher for LS1;and(4)the higher critical market-related risks perceived by herders were animal price and hay and corn ***,higher livestock price acted as a deterrent to diversifying into other livelihood strategies(LS2 and LS3).Finally,this study advocates for policies that will promote the land transfer market,adopt modern techniques in animal husbandry,improve the medium for disseminating market information to herders,and provide incentives for long-term livelihood transformation.

作者： Evangelia N. Sossidou Eleni Tsiplakou George Zervas Veterinary Research Institute Hellenic Agricultural Organization-DEMETER Thessaloniki 57001 Greece Nutritional Physiology and Feeding Agricultural University of Athens Athens 11885 Greece

This paper discusses recent research findings together with management schemes in preventing and managing of thermal stress by handling external and internal factors in livestock production systems. Preventive measures against thermal stress are described as basic structural adjustments and the modifications that can be implemented readily, according to animal health and welfare requirements and refer to （1） environmental modification and thermal comfort in various housing systems; （2） action on animals, such as genetic selection for breeds resistant to infectious disease, parasites and climate extremes; （3） action on feed and （4） action on staff handling the animals. Moreover, measures to be taken both in situations of chronic thermal stress and heat or cold strokes are presented as they are applied to （1） limit stress, （2） monitor the temperature felt by animals, （3） adapt diet and drinking water supplies and （4） correct physiological imbalances. Examples are given for different farm species （cattle, sheep, goat, poultry and pigs） and different production systems （intensive, extensive and alternative）. The paper concludes with a practical guide for the effective handling of thermal stress at farm level, summarizing the results from recent research studies on the specific topic.

Driving factors of direct greenhouse gas emissions from China's pig industry from 1976 to 2016

引用

Journal of Integrative Agriculture 2021年第1期20卷 319-329页

作者： DAI Xiao-wen Zhanli SUN Daniel MULLER Sichuan Center for Rural Development Research Sichuan Agricultural UniversityChengdu 611130P.R.China Leibniz Institute of Agricultural Development in Transition Economies(IAMO) Halle(Saale)06120Germany Geography Department Humboldt-Universitat zu BerlinBerlin 10099Germany Integrative Research Institute on Transformations of Human-Environment Systems(IRI THESys) Humboldt-Universitat zu BerlinBerlin 10099Germany

livestock cultivation is a significant source of greenhouse gas(GHG) emissions, accounting for 14.5% of the total anthropogenic emissions. China is responsible for a considerable share of the global livestock emissions, particularly caused by pork production. We used the Kaya identity and the logarithmic mean Divisia index(LMDI) to decompose the national annual GHG emissions from enteric fermentation and manure management in pig farming in China from 1976 to 2016. We decomposed the sources of the emissions into five driving factors:(1) technological progress(e.g., feed improvement);(2) structural adjustment in the livestock sector;(3) structural adjustment in agriculture;(4) affluence;and(5) population growth. The results showed that the net GHG emissions from the pig sector in China increased 16 million tons(Mt) of carbon dioxide equivalents(CO2 eq) during the study period. The decomposition analysis revealed that structural adjustment in agriculture, growing affluence, and population growth contributed to an increase of the GHG emissions of pork production by 23, 41, and 13 Mt CO2 eq, respectively. The technological progress and structural changes in animal husbandry mitigated emissions by –51 and –11 Mt CO2 eq, respectively. Further technological progress in pig production and optimizing the economic structures are critical for further reducing GHG emissions in China's pig industry. Our results highlight the dominant role of technological changes for emission reductions in the pig farming.

Utilization and management of organic wastes in Chinese agriculture:Past,present and perspectives

引用

Science China(Life Sciences) 2005年第z2期48卷 965-979页

作者： Rmheld V. Roelcke M. Institute of Plant Nutrition University Hohenheim 70593 StuttgartGermany Institute of Geoecology Technical University Carolo-Wilhelmina 38106 BraunschweigGermany

Recycling and composting of organic materials such as animal waste, crop residues and green manures has a long tradition in China. In the past, the application of organic manures guaranteed a high return of organic materials and plant mineral nutrients and thus maintained soil fertility and crop yield. As a result of rapid economic development coupled with the increasing urbanization and labour costs, the recycling rate of organic materials in Chinese agriculture has dramatically declined during the last two decades, in particular in the more developed eastern and southeastern provinces of China. Improper handling and storage of the organic wastes is causing severe air and water pollution. Because farmers are using increasing amounts of mineral fertilizer, only 47% of the cropland is still receiving organic manure, which accounted for 18% of N, 28% of P and 75% of K in the total nutrient input in 2000. Nowadays, the average proportion of nutrients (N+P+K) supplemented by organic manure in Chinese cropland is only 35% of the total amount of nutrients from both inorganic and organic sources. In China, one of the major causes is the increasing de-coupling of animal and plant production. This is occurring at a time when 're-coupling' is partly being considered in Western countries as a means to improve soil fertility and reduce pollution from animal husbandry. Re-coupling of modern animal and plant production is urgently needed in China. A comprehensive plan to develop intensive animal husbandry while taking into account the environmental impact of liquid and gaseous emissions and the nutrient requirements of the crops as well as the organic carbon requirements of the soil are absolutely necessary. As a consequence of a stronger consideration of ecological aspects in agriculture, a range of environmental standards has been issued and various legal initiatives are being taken in China. Their enforcement should be strictly monitored.
