The Program on Ecosystem Change and Society (PECS) is one of the international programs that can deliver relevant information to the International Platform on Biodiversity and Ecosystem Services. PECS will be able to contribute to PECS on knowledge on the interlinkages between biodiversity, ecosystem services and human well-being from a perspective complementary to other existing research programs. PECS is based on a comparative, place-based approach of networks of sites. PECS study sites will encompass a wide range of biophysical and societal conditions within which different levels of biodiversity, types of service delivery and human well-being conditions are found.
PECS will assess how societal decisions to manage ecosystems have led to the particular conditions founds within each site. It will also explore how different alternative changes in technologies and policies may lead to changes in both biodiversity conditions, ecosystem service delivery and well-being conditions. PECS will search for the identification of interactions across scales, such as fast and slow drivers of social and ecological change, thresholds, traps and time lags non-linear changes. PECS will seek to understand transformations toward or away from sustainable development with emphasis on the interlinkeages between biodiversity and other components of natural capital, the delivery of ecosystem services, and the consequences for societies. PECS will contribute to models on the evolution of biodiversity, natural capital, ecosystem services and human wellbeing with interdisciplinary, intersectoral, and multi-scale models, movement toward and away from sustainability, accounting for the full portfolio of ecosystem services that flow from a given landscape or seascape. PECS will contribute to IPBES also contribute to IPBES through capacity building in a wide range of methods and the use of diverse sources of information on the socio-ecosystem.
