1 Agroforests in the Humid Tropics: vanishing in South-East Asia, expanding in Africa? Hubert de Foresta IRD – AMAP Montpellier France WCA II, Nairobi August 2009

2 Agroforest dynamics at landscape scale South – East Asia: –Malaysia, Thailand: almost completely vanished –Indonesia: on-going conversion Africa: –Guinea, Cameroun, Ethiopia: expansion –Ghana: on-going conversion (Ruf, 2008) –Togo, Côte-d’Ivoire, others: no report…

Kalms Une approche géoagronomique pour l'analyse comparative des dynamiques spatio-temporelles des systèmes agroforestiers d'Afrique de l'Ouest et du Centre : Guinée – Cameroun. In : IRAG, CIRAD, IRD, ISAV. Atelier de réflexion Les agroforêts d'Afrique de l'Ouest et du Centre : dynamiques, performances et avenir ? du 11 au 15 novembre 2008 à Sérédou (Guinée): 9 pp. Research Need : duplication of such data supported studies regarding agroforest dynamics at landscape scale…

4 Rubber agroforest, Sumatra First ½ XXth century: the way to get rich… Changing socio-economic context, especially since the 1980’s… –Dramatic progress in monospecific rubber plantation productivity, increasing demographic pressure, decreasing land availability, growing integration into the market economy, growing monetary needs… –Oil-palm as a new opportunity since mid 1990’s… >>> Rubber agroforest: lower returns to labour and land… Massive on-going conversion of agroforests

5 Coffee-based agroforests, Guinea Relatively high population pressure (ca. 70 inh./km2), but… A low level of integration into the market economy… Coffee production is « The » way to get monetary income… The agroforest canopy trees provide a number and variety of NTFP’s useful and used in the daily life for household consumption… Expansion of agroforests at the expense of rainfed rice rotating cropping system…

6 Which future for agroforests? Agroforests are doomed to disappear when countries develop and rural areas increasingly integrate the globalized market economy… If nothing is done to support agroforests…

7 Which future for agroforests? Why support agroforests? –Because agriculture is not only about food prodution, but also about managing the environment (« multifunctionality », a corollary of the sustainable development paradigm). –Because in developed countries, the current trend for agricultural research and policy is to re-integrate biodiversity into agriculture. Agri-environmental schemes financially supporting biodiversity friendly agricultural practices; Agriculture and Biodiversity Action Plan (France, May 2009): « generalize agricultural practices favouring biodiversity »! –Because in agroforests, agricultural production and biodiversity conservation already go hand in hand…

8 Which future for agroforests? What can be done to support agroforests? improve competitiveness of agroforests by increasing their profitability without threatening their environmental value… –Site-specific, system specific, improvements: a room for cropping-systems agroforestry research… Rubber (a canopy tree) / Coffee (an understorey tree) Guinée (rainfed rice) / Cameroon (Cassava, yam, plantain) –Generic improvements: a room for policy-oriented agroforestry research…and for policy… Timber: agroforests everywhere offer a favourable environment for raising high value timber Payment for environmental services, especially biodiversity conservation (with adaptations to site and system specificity…)
