Ecosystem services are the benefits obtained from the environment that increase human well-being. Economic valuation is conducted by measuring the human welfare gains or losses that result from changes in the provision of ecosystem services. Bats have long been postulated to play important roles in arthropod suppression, seed dispersal, and pollination; however, only recently have these ecosyst...
The evaluation of ecosystem services is a tool to raise awareness about benefits of ecosystem functions for human well-being. In Brazil, few studies and reports assess ecosystem services in a watershed context. The aim of this paper is to fill this gap by assessing ecosystem services of Jacaré-Guaçu and Jacaré-Pepira Watersheds (São Paulo State, Brazil) in a temporal scale of 10 years. Land cov...
Despite increasing attention to the human dimension of conservation projects, a rigorous, systematic methodology for planning for ecosystem services has not been developed. This is in part because flows of ecosystem services remain poorly characterized at local-to-regional scales, and their protection has not generally been made a priority. We used a spatially explicit conservation planning fra...
Wetlands provide a diverse range of ecosystem services supporting livelihoods of many people. Despite their value, wetlands are continuously being degraded. There is scant information on individual wetlands, people’s dependency and their exploitation at a local scale. We therefore assessed wetland ecosystem services, the drivers of change and impacts of those drivers on ecosystem services and p...
Research on ecosystem services has grown markedly in recent years. However, few studies are embedded in a social process designed to ensure effective management of ecosystem services. Most research has focused only on biophysical and valuation assessments of putative services. As a mission-oriented discipline, ecosystem service research should be user-inspired and user-useful, which will requir...
Understanding the relationships between ecosystem services is important for promoting ecosystem service management and sustainable development. The relationships between ecosystem services have commonly been characterized as tradeoffs and synergies. Here, we report that a third type of relationship also exists, in which one ecosystem service constrains the other. Selecting the grassland and agr...
Ecosystem services are necessary, yet not sufficient for human well-being (however defined). Insufficient access to the ecosystem provisioning service of food is a particularly important factor in the loss of human well-being, but all ecosystem services contribute in some way to well-being. Although perhaps long obvious to ecologists, the links between ecosystems and aspects of human well-being...
Priorities for protecting ecosystem services must be identified to ensure future human well-being. Approaches to broad-scale spatial prioritization of ecosystem services are becoming increasingly popular and are a vital precursor to identifying locations where further detailed analyses of the management of ecosystem services is required (e.g., examining trade-offs among management actions). Pri...
