A guide to selecting ecosystem service models for decision-making. Lessons from Sub-Saharan Africa
Ecosystems are essential to human life, livelihoods and wellbeing. Many national policies and international agreements include goals to protect ecosystem services. A new guide – commissioned by the Ecosystem Services for Poverty Alleviation (ESPA) programme and written by Professor James Bullock of the Centre for Ecology and Hydrology (CEH) and Helen Ding of World Resources Institute (WRI) – helps readers to assess how ecosystem service models could support policy-making in their countries.
In order to manage ecosystem services sustainably, decision-makers need to understand the extent and condition of ecosystems. They must be able to predict the impacts of alternative policies or management decisions on the environment.
Frequently, there is not enough measured data on ecosystem services. In these situations, models can provide useful information based on assumptions from similar places. Modeling is especially useful in developing countries, where measured data may be scarce.
The guide is particularly suited to advisors and technical managers who are supporting policy-makers.
It is based on results from the 2013–16 WISER project, which assessed several ecosystem service modeling tools in sub-Saharan Africa. Policy advisors from Malawi and Uganda contributed actively to the guide’s development.
The guide includes:
- Advice on how models can inform different types of policy and programme decisions
- Guidance on how to consider technical capacity and resource needs, when selecting an appropriate model
- Case studies that draw on current policy issues and modeling experience in Africa.
The ESPA programme is funded by the United Kingdom’s Department for International Development (DFID), the Economic and Social Research Council (ESRC) and the Natural Environment Research Council (NERC).
