The impact of individual capabilities on the access to ecosystem services: a case study from the Loess Plateau, China

Abstract

Exploring how people access ecosystem services and revealing the individual capabilities that affect the accessibility of ecosystem services are important for obtaining a clear understanding of the contribution of ecosystem services to human well-being. Previous studies on ecosystem services have incorporated too little empirical research on the accessibility of ecosystem services and on the individual capabilities that affect accessibility. We chose the ecologically fragile and economically underdeveloped Loess Plateau as the research area because local farmers in this area are dependent on ecosystem services. The importance and accessibility of ecosystem services were evaluated on the basis of questionnaire surveys and semistructured interviews. The results showed that crops, meat, and water yield were the most important ecosystem services but were the most difficult to access. In contrast, fruit and soil fertility were easier to access. Furthermore, we determined the individual capabilities of local farmers based on Nussbaum's capabilities list as well as the actual conditions for local farmers and explored the impact of individual capabilities on the accessibility of ecosystem services. The results showed that local ecological knowledge and the ability to socialize were the key individual capabilities determining whether local farmers can access ecosystem services. Compared with farmers who have a formal education, farmers with rich local ecological knowledge can more easily access to crops and erosion control. The ability to socialize reflects the exchanges or donations of ecosystem services among farmers, which increase the accessibility of fodder and organic fertilizer. Physical health, financial capital, and other individual capabilities also have an impact on the accessibility of certain ecosystem services. Therefore, improving these individual capabilities is of great value for improving farmers' well-being. In policy-making and community management, the government needs to consider the development of farmers' individual capabilities in addition to considering poverty alleviation measures.
