Sustainable plasticulture in Chinese agriculture: a review of challenges and routes to achieving long-term food and ecosecurity

引用

Frontiers of Agricultural Science and Engineering 2024年第1期11卷 155-168页

作者： Samuel j.CUSWORTH William j.dAVIES Martin R.MCAINSH Carly j.STEVENS Weilu WANG Lancaster Environment Centre Lancaster UniversityLancasterLA14YQUK The Institutes of Agricultural Science and Technology development Yangzhou UniversityYangzhou 225009China

Plastic pollution is global concern, affecting most aspects of global food production systems. Plasticulture, a practice used in agriculture to improve crop quality and quantity, among other factors, is a significant source of plastic pollution. This review examines the extent of plasticulture in China, the implications of the practice across decades of use and the legislative instruments used to resolve those issues. It briefly assesses the effectiveness of these policies and proposes possible future innovations to promote increases in long-term food and eco-security, where sustainable plasticulture is a key agent for change. While plasticulture has increased agricultural productivity in growth-limiting conditions, plastic pollution in agricultural soils has become acute in China. Consequently, plastic pollution is having deleterious effects on soil health and in turn, crop productivity in China. Plastic pollution in agriculture is a multifaceted issue and so proposed solutions should be informed by this complexity. Current measures do not reflect a holistic approach to solving this socioecological challenge and adopt a top-down approach, with little or no supportive mechanisms. Future recommendations need to consider the particular set of conditions that influence the production, use and end-of-life management of agriplastics,specific to the environmental, economic and social conditions in each location.

THE ATHENIAN ASSEMBLY ANd COUNCIL: CONTINUING PROBLEMS

journal of Ancient Civilizations 2019年第1期34卷 39-67,126,127页

作者： P.j.rhodes University of durham

The council with its limited membership and the assembly open to all citizens were important elements in the public life of Athens,and indeed of most Greek cities,and how they functioned is an important part of what we need to know in order to understand their public life;but there are still questions to which we do not have certain answers,and in this paper I focus on *** about the mechanisms is not all that we need to know;but for a city whose mechanisms were well developed,as those of Athens were,knowing about the mechanisms,and the opportunities and the limitations which they provided for the men active in politics,is an important part of what we need to know–as *** has emphasised in an article in which he justifies his approach against the criticisms of scholars who think other kinds of question more important.

Ferroptosis,an iron-dependent cell death:Ferroptosis is a type of regulated necrosis,characterized by redox-active iron accumulation and increased free radical production derived by Fenton chemistry,that triggers oxidation of polyunsaturated fatty acids in phospholipids,loss of cellular membranes integrity,and leakage of intracellular contents.
