The Future Earth approach and its
importance for understanding land use
change in Africa
Berlin, 19 March 2014
Flash talk session, Global Land Project conference
Future Earth and its approach• A global platform for international research collaboration on
global environmental change and sustainable development• Provides integrated research on major global change
challenges and transformations to sustainability • Strengthens partnerships between researchers, funders and
users of research through co-design of research• Is solutions-oriented, aiming to generate knowledge that
contributed to new more sustainable ways of doing things
Objective: To provide the knowledge required for societiesin the world to face risks posed by global environmental change and to seize opportunities in a transition to global sustainability
Meets African land use dynamics
• Complex and multi-scale, as global and regional change intersects with local systems and practices
• Diverse and non-linear, as bio-physical and anthropogenic processes interact to produce patterns of both enrichment and degradation
• Represented and valued in multiple ways by different stakeholders : Beyond degradation narratives? Sustainability of what for whom? Whose knowledge counts?
Needs research that integrates the knowledges and perspectives of diverse stakeholders – including local land users
To build a richer picture through respectful deliberation and dialogue
What can we learn from existing activities – within and beyond current GLP/GEC communities?
