Ecosystem services offer us multiple benefits including the material and non-material benefits of provisioning, regulating, supporting and cultural services. These benefits, possessing not only monetary but also major non-monetary values, are reflected on the constituents of human well-being, including secure resource access, sufficient nutritious food, shelter and health. Certainly, ecosystem services are essential for directly and indirectly assuring the food security and nutritional diversity of rural communities, with major implications for the poorest and most vulnerable households. This is, for instance, through the provision of wild foods (vegetables, fruits, mushrooms, animal meat, fish, edible insects) from a wide array of farming and forest landscapes; the provision of fuel-wood for cooking and animal feed; the support of agriculture, agroforestry and livestock production; preventing risks of natural disasters and soil erosion, while supporting water conservation; and enabling income-generation activities. As a result, the Ecosystem Services Research Theme, part of the Decision and Policy Analysis Research Area (DAPA), at CIAT decided to further explore the relations between ecosystem services and food security as a new line of investigation.
According to the World Food Summit (FAO 1996), food security exists ‘when all people, at all times, have physical and economic access to sufficient safe and nutritious food that meets their dietary needs and food preferences for an active and healthy life.’ The FAO (2008) further identified four main dimensions (or pillars) that should be simultaneously present in order to be food secure: availability, access, utilization and stability. Availability refers to have enough supply of good quality food; access is related to having adequate economic resources and/or physical access or entitlements to acquire food; utilization refers that the food consumed offers the energy and all nutrients required for a healthy life, involving food preparation, dietary diversity, access to clean water and intra-household distribution of food; finally, stability assures that availability, access and utilization are satisfied throughout the year and at all times. In this new line of investigation, ecosystem services will be analyzed through the lens of these four dimensions and agriculture will be approached beyond food productivity.
The first project along this line of investigation is ASSETS ‘Managing ecosystem services for food security and the nutritional health of the rural poor at the forest-agricultural interface’, which is conducted as part of an international consortium of different organizations. ASSETS investigates the relations between ecosystem services, food security and the nutritional health of rural and indigenous communities from the Lower Caqueta basin and Ucayali, located in the Colombian and Peruvian Amazon respectively, as well as in Lake Chilwa catchment, Malawi. It is planned to further develop research with the main objective to have a better understanding of the direct and indirect contributions of ecosystem services to food security and nutrition in impoverished rural areas, and ultimately the implications of ecosystem services for the wellbeing of the rural poor.
