FULL TIME-SPACE GOVERNANCE STRATEGY AND TECHNOLOGY FOR CROPLAND NON-POINT POLLUTION CONTROL IN CHINA

Frontiers of Agricultural Science and Engineering 2023, Volume 10, Issue 4,   Pages 593-606 doi: 10.15302/J-FASE-2023522

Abstract:

Ensuring food safety while reducing agricultural non-point source pollution is quite challenging, especially in developing and underdeveloped countries. Effective systematic strategies and comprehensive technologies need to be developed for agricultural non-point source pollution control at the watershed scale to improve surface water quality. In this review, a proposal is made for a full time-space governance strategy that prioritizes source management followed by endpoint water pollution control. The 4R chain technology system is specifically reviewed, including source reduction, process retention, nutrient reuse and water restoration. The 4R chain technology system with the full time-space governance strategy was applied at the scale of an administrative village and proved to be a feasible solution for reducing agricultural non-point source pollution in China. In the future, a monitoring system needs to be established to trace N and P transport. Additionally, new smart fertilizer and intelligent equipment need to be developed, and relevant governance standards and supportive policies need to be set to enhance the efficacy of agricultural non-point source pollution control.

INTEGRATED CROP-LIVESTOCK SYSTEMS: LESSONS FROM NEW YORK, BRITISH COLUMBIA, AND THE SOUTH-EASTERN UNITED STATES

Frontiers of Agricultural Science and Engineering 2021, Volume 8, Issue 1,   Pages 81-96 doi: 10.15302/J-FASE-2020365

Abstract: Livestock production in the United States (US) and Canada is diverse, but shows a common trend in most livestock sectors toward fewer farms producing the majority of animal products despite a large number of farms still small in production scale. The migration to larger and more concentrated animal feeding operations in beef finishing and poultry, swine, and dairy production allows processors to streamline supplies to meet market demand for abundant, low-cost livestock products, whether that be for packaged meat, dairy products, or eggs. With concentration of livestock operations comes the challenge of managing manures. When sufficient land is available and nutrients are needed, livestock manure is an excellent nutrient source and land application is the preferred method of recycling this resource. However, when livestock production is constrained in a geographical area and animal densities are high, manure may become an environmental liability with potentially greater risk for runoff and leaching of nutrients, emission of odors, ammonia, and greenhouse gases, and release to the environment of pathogens and chemicals of emerging concern. Addressing these challenges now and into the future requires learning from mistakes and adopting successful approaches. We describe different levels of integration between livestock and crop producers in New York, British Columbia, and the south-eastern US as learning opportunities to improve economic and environmental sustainability. Examples show that effective solutions should recognize (1) manure has value and is not just a cost, (2) farmers, farm advisors, extension educators, nutrient management planners, crop advisors, nutritionists, state agency personnel, regulators, and university researchers need to be active participants in development of solutions, and (3) change to a sustainable future requires a combination of government regulation and outcome-based incentives.

Potential Analysis and Policy Recommendations for Restructuring the Crop Farming and Developing Forage Industry in China

Li Xianglin,Shen Yuying and Wan Liqiang

Strategic Study of CAE 2016, Volume 18, Issue 1,   Pages 94-105 doi: 10.15302/J-SSCAE-2016.01.012

Abstract:

Developing forage/livestock farming in cropping areas can help to enhance the integration, in both spatial and temporal dimensions, of forages into food and/or cash crop systems and thus to improve the use efficiency of agricultural resources. Currently the advantages of forages in cropping areas have not been well exploited mainly because of the traditional thinking of agricultural production and the government policies that favour food crops. In this article, the current status and future potential of forage industry development on croplands are analyzed and relevant policy recommendations are proposed.

Using balance of seasonal herbage supply and demand to inform sustainable grassland management on the Qinghai–Tibetan Plateau

Xinquan ZHAO, Liang ZHAO, Qi LI, Huai CHEN, Huakun ZHOU, Shixiao XU, Quanmin DONG, Gaolin WU, Yixin HE

Frontiers of Agricultural Science and Engineering 2018, Volume 5, Issue 1,   Pages 1-8 doi: 10.15302/J-FASE-2018203

Abstract: To mitigate the impacts of grassland degradation on the Qinghai–Tibetan Plateau (QTP), in recent decades China has been implementing large-scale conservation programs and has invested about 42 billion CNY (7 billion USD). However, these programs are faced with major challenges involving trade-offs between ecological function, livestock production and income of pastoralists. Scientific assessments, as well as technical and policy issues, have not fully captured the complex ecological, social and economic dynamics of the challenges facing grassland management on the QTP. Pastoral livestock production on the QTP is characterized by imbalance in both quality and quantity between livestock seasonal nutrient requirements and herbage production, which forces pastoralists to keep larger numbers of livestock for longer periods, leading to overgrazing. To solve these problems, an integrated crop-livestock system is promoted to improve the efficiency of livestock production and conserve natural grassland as well for a sustainable system for the QTP.

The Impact of Cropland Spatial Pattern Change on Grain Production in China

Li Yuanyuan, Tan Minghong, Zhang Hongqi

Strategic Study of CAE 2018, Volume 20, Issue 5,   Pages 90-95 doi: 10.15302/J-SSCAE-2018.05.014

Abstract:

Cropland is the basis of grain production.In recent decades, the spatial pattern of cropland in China has changed significantly, which has causedacreage decreased in Huang-Huai-Hai Plain; the main source of new cropland during the study period wasgrassland (46.9%), and the lost cropland was mainly converted to forest land (36.6%) in the first ten, while the newly reclaimed cropland had lower crop productivity.
