Jointness in production and farmers' willingness to supply non-marketed ecosystem services

This paper highlights how farmers' willingness to supply non-marketed ecosystem services (ES) is influenced by whether or not the non-marketed ES are produced jointly with agricultural products. When marketed products and non-marketed ES share some production inputs the production relationships between the two may be complementary, competitive or substitutive. Using a cost minimization framework, it is shown how complementary relationships lead to costless voluntary provision of non-marketed ES (typically the case for ES that are supportive of provisioning ES for marketed farm products). It is also shown how competitive production relationships lead to provision of non-marketed ES at lower cost than when non-marketed ES are direct substitutes for farm products or are produced outside of agriculture. The paper closes by showing how the minimum willingness to accept (WTA) payment for ES that are complementary/competitive is less than or equal to the minimum WTA for the same ES produced in substitute or independent production relationships.

Auction winning,social dynamics and non-compliance in a payment for ecosystem services scheme in Indonesia

Conservation auctions for payment for ecosystem services (PES) are useful to identify the levels of incentives that will cover the opportunity costs of farmers supplying ecosystem services. Although auctions are increasingly used for allocation in PES schemes, the factors that lead to their successful implementation and eventual environmental outcomes are poorly understood in developing countries. We investigated the socio-economic and institutional contexts that led to smallholders' auction winning and eventual compliance using linear mixed-effects models, and post-auction and post-contract surveys. We employed a case study of a conservation contract preceded by a sealed-bid, multiple round, uniform price auction for watershed services from coffee farmers in Lampung, Indonesia. The auction participants presented low education levels, low asset endowments and small plot sizes. The study obtained evidence that farmers with larger plot areas were more likely to win the contracts, suggesting economies of scale. Most farmers considered the auction a fair self-selection mechanism to allocate contracts where allocation was not influenced by power or social rank. Non-compliance was associated with labor availability constraints, short duration of land ownership and existence of previous conservation applications, suggesting lax of capability to invest in applying conservation agriculture. Final bids were however not good predictors of compliance, among other factors, calling into question the potential of auctions to elicit the actual incentive from the farmers. Ensuring that farmers understand the purposes of auctions for effective contract allocation beyond a mere game and identifying farmers that might encounter difficulties fulfilling the contract could increase the likelihood that such a PES scheme would be successful.     

农民宅基地退出差异性受偿意愿及其影响因素分析

研究目的:宅基地退出工作能否顺利推进与退地补偿息息相关,研究宅基地退出中农民差异性受偿意愿及其影响因素,以服务决策。研究方法:基于重庆市890份农民实地调查数据,应用多元离散选择模型(Logit)进行定量研究。研究结果:(1)传统农区的农民更愿意选择货币补偿;城乡结合部(街道办)的农民更愿意选择安置补偿;农民修建补偿选择率总体偏低,区位差异并不明显;(2)农民货币受偿意愿影响因素主要包括受教育程度、家庭主要成员是否定居城镇、非农务工收入、新居住地适应性;(3)农民安置受偿意愿影响因素主要包括年龄、农房是否自住、退地补偿是否有截留、村基础设施状况;(4)农民修建受偿意愿影响因素主要包括农房造价、农房是否新建、退地补偿是否有截留;(5)影响农民受偿意愿的因素存在较大差异,同一因素可能对农民选择受偿意愿产生不同的影响,但没有一个自变量同时对三个因变量产生显著影响。研究结论:应针对农民受偿意愿差异及其影响因素,实行产异化的补偿措施,在经济发展相对滞后的传统地区,强化村落基础设施建设的同时,加大现金补偿力度。对于经济较为发达、区位条件较好的城乡结合部地区,应加大安置补偿力度,以保障退地农民的居住权。

林业生态建设的社会经济驱动力评价:来自四川和湖北的实证

中国长期以来从事林业生态建设工程,如天然林保护工程和退耕还林工程。然而,中国的环境问题如生物多样性丧失、水土流失、沙漠化进一步恶化。该研究目的旨在从林农户视角调查林业生态建设的社会经济驱动力,基于对171林农户的调研,采用多变量回归模型,对其愿意接受补贴,从事生态环境生产进行分析。结果表明,94%的林农户愿意接受补贴,从事生态环境生产。但是,补贴高达每年每公顷6033元。计量结果进一步揭示,受教育程度越高、距离城市越远、农业收入较高,其索要的生态补贴就越高。与此相反,部分在自己地上劳作的农户和农地面积较大的农户,其索要的生态补贴就较低。
