Forests sustaining agriculture: A systematic review of multi-functional landscapes for food security and biodiversity conservation

  1. 1. Samson Foli Terry Sunderland James Reed Jessica Clendenning Jake Snaddon Gillian Petrokofsky Forests sustaining agriculture A systematic review of multi-functional landscapes for food security and biodiversity conservation
  2. 2. Objectives of this discussion  To gain insight and feedback on relevance of our research project.  To explore and help merge potential research topics that will contribute to the core research question  To define main research question in plenary with contribution from important stakeholders and explore potential collaboration
  3. 3. Multi-functional Landscapes (Sayer et al. 2013) “Areas that have the potential to provide material and immaterial good to satisfy social needs” Barkmann et al. 2004 Forest-Agricultural Landscapes provide food, fibre and fuel through ecosystem services provisioning Agricultural systems within the landscapes impact ecosystem services and biodiversity Perfecto et al 2009
  4. 4. Problem statement There is little integration of agriculture and biodiversity conservation priorities in Forest-Agriculture landscapes. Partly due to limited knowledge on the socio-ecological flows of services and values that support sustainable agriculture and conservation of ecosystem services in the landscape. Objectives Establishing the evidence base on multifunctional landscapes for food and biodiversity conservation demands. Identify, appraise and synthesize the existing research on the importance of ecosystem services and dis-services on food production, the impacts of agriculture on biodiversity and models of landscapes that combine different human demands without comprising forest ecosystems.
  5. 5. Justification  The need for better understanding of landscape approaches for food security, biodiversity conservation and sustainability of ecosystem services.  Prioritise research to contribute to evidence based policy making on forestry and food security.  Undertake further data collection to answer important questions (derived from results of this systematic review) and contribute to filling knowledge gaps.
  6. 6. Landscape components of interest Population Intervention Comparators Outcomes Agricultural landscapes in the proximity of tree cover Data collection and analysis on ecosystem services, biodiversity and agricultural production in forest- agriculture landscapes and the interactions between them Crop production, biodiversity (conservation/degra dation), food security indicators within and outside proximity to tree cover The analysed impact (quantitative/qualitati ve) of biodiversity, ecosystem function, food security on identified Comparators
  7. 7. Scoping study Main terms • Forest-agriculture landscapes • Agroforestry systems • Farming/cropping systems Exposure terms  Ecosystem services and dis-services Outcome terms  Crop productivity  Resource use efficiency (RUE)  Biodiversity conservation/degradation OR/AND OR/AND

  9. 9. Research topics for discussion
  10. 10. Topic 1 Multi-functional landscapes for food and biodiversity conservation  What is the contribution of ecosystem services in multi- functional landscapes to agriculture and food security?  How do different agricultural production systems in forest- agricultural landscapes benefit from and affect biodiversity to varying extents?  Are smallholder production systems enhanced by proximity to trees and forests and what is the impact of these systems on forest biodiversity and sustainability of ecosystems services provisioning?
  11. 11. Topic 2 Ecosystem services and dis-services in forest-agriculture landscapes.  What are the ecosystem services and dis-services in forest- agriculture landscapes how do they contribution to agriculture and food security?  What are the inter-linkages between ecosystems services and dis-service, agricultural systems and biodiversity and how do these interact in forest-agriculture landscapes?
  12. 12. Discussion
  13. 13. Thank you
  14. 14. Review timeline…  Gauging relevance of systematic review in expert discussion  30th September 2013  Complete draft protocol  early November 2013  1st stakeholder meeting  late November 2013  Submit draft protocol  early December 2013
  15. 15. Linking Ecosystem Services and Food Security (Richardson et al. 2010)  Wild pollinators enhance flowering and fruit set (Garibaldi et al. 2013)  Buffering of extreme weather conditions to allow for cultivation (Tougiani et al. 2009)  Nitrogen fixation by trees substitute for purchased inputs and better soil fertility (Sendzimir et al. 2011)  Nutrient cycling between tree-fallow-crop ecosystems (Power 2010)  Water regulation and conservation for crop uptake in dry season (Jose 2009)
