background informal payments for health care, which are common in many countries, can have negative effects on health care access, equity and health status as they lead people to forgo or delay seeking care, or to sell assets to pay for care. many countries are putting reforms in place with the aim of reducing informal payments. in order to be successful, such policies should be informed by the...

We present an integrated modeling framework for simulating land-use decision making under the influence of payments for ecosystem services. The model combines agent-based modeling (ABM) with Bayesian belief networks (BBNs) and opinion dynamics models (ODM). The model endows agents with the ability to make land-use decisions at the household and plot levels. The decision-making process is captur...

In prioritising investment in natural capital, site-scale indicators are increasingly used to capture finescale variation inherent in complex ecosystems. However, site assessment is costly, has high skill demand, and is time-consuming. We assess the marginal gain associated with including site-scale indicators in metrics typically used by agri-environmental stewardship schemes and payments for ...

We evaluated a program of payments for ecosystem services in Uganda that offered forest-owning households annual payments of 70,000 Ugandan shillings per hectare if they conserved their forest. The program was implemented as a randomized controlled trial in 121 villages, 60 of which received the program for 2 years. The primary outcome was the change in land area covered by trees, measured by c...

The growth economy imposes multiple crises on humanity and the natural world. To challenge this economic growth imperative, the degrowth movement emerges as a dissident response. Although within an economic growth perspective, payments for ecosystem services (PES) have also been proposed to attenuate the negative impacts of capitalism, as a redistributive mechanism that is claimed to deliver eq...

This paper evaluates a Payments for Ecosystem Services (PES) program in western Uganda that offered forest-owning households cash payments if they conserved their forest. The program was implemented as a randomized trial in 121 villages, 60 of which received the program for two years. The PES program reduced deforestation and forest degradation: Tree cover, measured using high-resolution satell...

This paper analyzes whether monetary incentives modify cooperative behavior in activities that have been traditionally unpaid. We provide a simple theoretical framework and exploit variation over time in community access to Payments for Ecosystem Services (PES) within Mexican common property communities, to analyze whether payments increase work in forest protection activities, which are increa...

informal payments to health care providers have been reported in many african, asian and european countries. this study aimed to investigate different aspects of these payments that are also known as under-the-table payments in iran.this is an in-depth interview-based qualitative study conducted on 12 purposively chosen clinical specialists. the interviewees answered 9 questions including the o...

in this paper, we report an investigation of changes in land use and ecosystem services on loess plateau in northern shaanxi province from 1978 to 2004. we used three landsat tm and/or etm data sets to estimate changes in the size of five land-cover/land-use categories, and we also used previously published value coefficients to estimate changes in the value of ecosystem services delivered by e...
