Farmers' Willingness to Pay( WTP ) for Reducing Agricultural Non-point Source Pollution: Based on the Empirical Analysis of 453 Farmers

With the rapid development of modern agriculture,agricultural non-point source pollution becomes increasingly serious in China,improving farmers' environmental protection consciousness plays a very important role in the reduction of agricultural non-point source pollution,and the WTP of Farmers for controlling agricultural non-point source pollution strongly reflects the strength of their environmental protection consciousness. Therefore,this investigation and study choose rural areas of five counties from Chongqing city and Zhejiang province as our sample,respectively make interview survey with the WTP(money or voluntary work) of farmers for improving local water and soil quality. Based on the statistical analysis of survey data,this study also takes empirical test and analysis with the influence factors on the WTP of farmers for reducing agricultural non-point source pollution. The analysis and conclusions of this research provides the supports in theory and practice for optimizing farmers' behavior,promoting the management of agricultural non-point source pollution and implementing new rural construction goal.

Coordinating environmental protection and agricultural development: a village-based case study for promoting green transformation

Balancing ecological preservation with sustainable agricultural practices is a global issue. Erhai Lake has felt this challenge keenly. To address it, in 2022, a Science and Technology Backyards(STBs) project was launched in Gusheng Village. The goal of this is to care for the environment while ensuring that farms and farmers can thrive sustainably. The uniqueness of the Erhai STB arises from its interdisciplinary integration, encompassing fields such as ecology, agronomy and social science, resulting in specifically-designed solutions for the Erhai context. While this model aligns with broader STB paradigms, its distinctive edge lies in technological innovation and robust support mechanisms for local agricultural stakeholders. This paper describes the methodology and outcomes of the STB initiative, highlighting its pivotal role in spearheading sustainable transition in Erhai. Preliminary findings underscore the potential of the STB model as an efficacious tool for harmonizing environmental conservation and agricultural practices, that are both financially and environmentally sustainable, rendering it a potential model for comparable regions in China and other counties.

Urban Market-Gardening in Parakou (Republic of Benin): Spatial Dynamics, Food Security, Protection of the Environment and Creation of Employments

Nowadays, African cities are subjected to upsets which result from the extraordinary growth of urban populations. The growth of the population of cities has induced some changes in the structure of the activity of those cities. Agriculture which was formerly confined to the countryside henceforth develops in the urban area and occupies a preponderant place as a strategy of survival, of insertion and of food supplying of the city-dwellers. It has become an activity integrated to the urban tissue through systems of occupying and exploitation of land in the urban area. Population growth (4.81%) between 2002 and 2013 is a critical poverty rate (65%) of the population of Parakou city, entailing a misery perceptible in all its social and economic dimensions. The market-gardening activity has integrated itself to the urban tissue. The objective of this study is to understand how urban agriculture through market-gardening can be a solution for rural farmers who have moved to Parakou city. In this study, documentary research, interviews and field observation are used for data collection. The main results to be signaled among others are: evolution and status of the market-gardening areas in Parakou, the reduction of food insecurity with the permanent availability in quantity and in quality of market-gardening products accessible to the population: the protection of the environment through the drainage of the urban area and the preservation of the diversity of vegetables;the increase of the income of the households of the farmers and the creation of employments.

AGRICULTURAL ENVIRONMENT PROBLEMS AND COUNTERMEASURES IN CHINA

China is facing the three major agroenvironment problems, which include: chemical pollution, abnormal ecological balance and natural resource deterioration. These environment problems have depleted part of the comprehensive agricultural productivity and hence become a resistance to the further development of agriculture. A number of measures have been taken for controlling over pollution and ecosystem declining. But for the sustainable development the more efforts are suggested to make, including the more stern measures in the population control, adopting the new techniques of saving natural resources and high efficiency, encouraging a frugal life style as well as paying more attentions to the research on the agricultural environment protection.

生态环境保护督察与农业绿色技术创新:县域政府竞争的调节效应

统筹生态文明建设与农业农村高质量协调发展对实现中国式现代化意义重大。利用2012—2021年中国县级面板数据,通过渐进DID分析生态环境保护督察作为准自然实验与农业绿色技术创新的因果关系。研究发现:生态环保督察通过资源调控、纵横联动、监督威慑、约谈问责等多元化的行为,形成要素集聚、组织变革、文化重构及服务整合等多种效应显著促进了农业绿色技术创新;县域政府竞争对这一关系通过“创新补偿效应”和“遵循成本效应”起到先增后减的倒U形非线性调节作用;异质性分析发现,环保督察政策对农业绿色技术创新的影响会因地理区位、粮食生产区域属性以及电子商务示范县资格的不同呈现出差异化特征。因此,在实施严格的生态环境保护督察的同时,应充分考虑县域政府竞争强度和县域差异,有效推动农业绿色高质量发展。
