This project will study different dimensions comparing the ‘re-greened’ with ‘conventional’ areas of agro-eco systems, looking into both social and biophysical aspects.
The Sahel is a region where poverty and vulnerable agro-eco systems are converging into extremely challenging conditions for development opportunities. However, in the last 15 years, patchy island of re-greening have occurred, indicating that vegetation have been increased despite the challenging rainfall variability, poor and infertile soils and exponential population growth.
Although some of the re-greening can be explained by increased seasonal rainfall, emerging cases suggest a more complex active human management of the landscape. Thus, there are indications that wise management of landscape resources can generate and increase landscape productivity, incl. ecosystem services, even under these challenging biophysical conditions.
This inter-disciplinary research project will study different dimensions comparing the ‘re-greened’ with ‘conventional’ areas of agro-eco systems, looking into both social and biophysical aspects. We ask what constitutes a ‘re-greened’ area? What are the ecosystems that can be restored and enhanced in re-greened versus ‘conventional areas? How much does the generation of ecosystem services differ in quality and quantity? How can re-greening happen, and does it need external push to be achieved? And how can this knowledge of systems change help alleviate poverty and possibly adapt to a highly uncertain future in current non-greened areas?
The project will have a 1-year partnership and piloting phase which aims to:
