PRESA - Pro poor Rewards for Environmental Services in Africa - aims at improving the livelihoods of smallholders living in the highlands of Eastern and Western Africa by enhancing fair and effective environmental service rewards. PRESA is run by the World Agroforestry Centre (ICRAF).

PRESA activities are designed in the form of action research and practical experience to directly influence and engage key stakeholders in active learning on payments or rewards for environmental services. This approach is aimed at catalysing policy support and private sector participation in environmental service agreements.

presa
Egoh. B. N. et al. 2012 _ Elservier. Over exploitation of resources coupled with large scale agriculture threatens both ecosystem services and livelihoods. The need to safeguard ecosystem services is urgent. There are some efforts to safeguard ecosystem services in Africa.

These challenges are compounded by the land tenure situation in Africa.

Ecosystem services in biologically diversified versus conventional farming systems: benefits, externalities, and trade-offs

presa
Kremen, C., & A. Miles. 2012 - Ecology and Society. Agrobiodiversity is sustained by diversified farming practices and it also supplies multiple ecosystem services to agriculture, thus reducing environmental externalities and the need for off-farm inputs. This study compares biologically diversified farming systems with conventional farming systems, and 12 ecosystem services: biodiversity; soil quality; nutrient management; water-holding capacity; control of weeds, diseases, and pests; pollination services; carbon sequestration; energy efficiency and reduction of warming potential; resistance and resilience to climate change; and crop productivity.
