Agrobiodiversity Research Challenges: Sustainable Intensification, Buffers, Filters, and Land Sharing

This research explores the challenges of sustainable intensification in agrobiodiversity, including the use of buffers, filters, and land sharing. It discusses the impact of various factors such as rural-urban migration, control of water scarcity, and the role of elites. The study also examines the convergent and divergent models of territorial configuration and their effects on landscapes and livelihoods.

  3. Variability of climate Variability of water flows Human vulnerability to floods & droughts Vulnerability range Resiliency range Tolerated range Landscape filter & buffer functions Currently increasing Currently decreasing Focus of ‘adapta-tion stragegies’? Preventable increase in exposure

  4. Exter-nal influen-ces & their Pat-terns of va-riability Landscape as Socio-Agro-Eco-System I M P A C T System of primary interest Filters: reducing lateral flows and conse-quent external impacts Immediate response medium/long term Resistance/ tolerance: absorbing external shocks Vulnera-bility to external change & varia-bility + Trans-mis-sion E x p o s u r e Buffers: reducing varia-bility by tempo-rary storage Resilience: bouncing back from temporary disturbance Sustainagility: resource base for further change Adaptation: change in sys-tem properties, reducing vulner. Adaptive Capacity

Social stressors originating within and among community/ies Persistence Change sustainagility Shielding networks Economic stressors due to market fluctuations & policy shifts Climatic stressors: means, variability and change Adapting/innovating Coping S Market access & insurance H Landscape buffers & filters 2 1 6 4 3 5 Pover-ty?

  6. Field-level intensification Landscape-level intensification

  7. Where would you like to see more trees?

  8. Configurational heterogeneity Compositional heterogeneity

  9. Participatory resource mapping followed by simulation board game with agents of change: seeking contracts for logging or oilpalm conversion, or agreements on forest protection and ecolabelling (Photographs: Grace Villamor)

  10. Extensively used landscape Fully intensified landscape components

  11. Terrain <20 km-2 ~50 km-2 ~200 km-2 1000 km-2 Malaria control

  12. Farms are decision points across spatial, temporal and institutional scales Global institutions But a major challenge remains in reconciling 3 time scales relevant to various decision makers: National institutions Globe  institutions National economy Nation Product value chains Water-shed  space Desakota network Land-scape Community  time Farm Persistence Efficiency Patch/field Change Population Organism Gene Jackson, L.E., van Noordwijk, M., Bengtsson, J., Foster, W., Lipper, L., Pulleman, M., Said, M., Snaddon, J. and Vodouhe, R., 2010.

  13. Initial use A Degra- dation B C Rehabilitation Critical loss of ecological functions EU Trade-off REF/RAF: convex, concave, win-win after lose-lose D Relative ecological function (REF) Relative agricultural function (RAF) - provisioning

  15. Sustainable Weighting of Economy-Ecology Tradeoffs: Organized Reduction or Stretching Our Use of Resources?  (SWEETorSOUR?) This may be societal optimum, but requires SWEET Production Possibility Frontier Getting here may turn SOUR

  16. We need empirical data, comparative analysis of how SWEET could be made to work and how SOUR can be avoided. Comparison of 8 sites in a global network starts to give insights… Jackson et al under review Old-growth forest

  17. Jackson et al., under review Reliance on natural capital & ecolo-gical processes for production Agrotechnical intensification

  18. Field-scale actions Landscape-scale actions Jackson et al., under review

  19. Key research challenges • Quantify buffer & filter functions at patch/ field/landscape scalesunder influence of ‘intensification’ (or alternative intensification pathways) • Quantify need for increase in buffer/filter functions in response to increased climate variability • Social & economic institutions to support SWEET and avoid SOUR
