Project INTERREG CPES (Channel Payment for Ecosystem Services)

The project INTERREG CPES aims to increase water quality by developing PES (Payment for Ecosystem Services) schemes. PES remunerate the farmer, provided by public or private buyers, in return for the adoption of practices that reduce losses of nutriments (P, N, or generally erosion) from their plots.

Intensive agriculture and lack of plant coverage on farmland promotes erosion and loss of essential plant nutrients such as Phosphate (P). Very often these are transported and deposited into nearby waterbodies leading to eutrophication, for which P is the responsible factor in fresh waters. As a consequence, proliferation of algae and cyanobacteria follows, decreasing water quality and biodiversity.

Besides nutrient loss from the soil, erosion significantly reduces soil carbon (organic matter and anorganic carbon), which is the largest terrestrial carbon (C) pool stored in soil. The loss of soil C is moreover accelerated by certain agricultural practices; causing C returning to the atmosphere. Finally, these soil degradation processes directly impact crop production.

Aim of this postdoc is to review the available literature in order to connect the importance of soil C for soil functioning including P retention and bioavailability. This will lead to improve the possibilities for PES schemes, connecting the requirements of farmers (PES sellers) to interest of PES buyers. Selected agriculture practices will at the same time increase carbon sequestration and phosphorus retention in agricultural soils. PES can thus be implemented to ameliorate both climate change and water quality, and simultaneously increase biodiversity.
