Agricultural landscapes play a centrally important role in producing and conserving ecosystem services, because they are such a dominant role in land use. On the one hand are the ‘provisioning’ services—productiion of goods like food, fuel, fiber, etc. On the other side are ecosystem services providing clean air, fresh water, flood protection, pest and disease regulation, etc. These ecosystem services provide direct and indirect benefits for the economy and people’s livelihoods, and thus have an economic value.
Conventionally, it has been assumed that tradeoffs between agricultural production and biodiversity conservation objectives are unavoidable. However, in many circumstances, agricultural practices depend and capitalize upon the inherent benefits and services provided by natural ecosystems, while many farming, herding, forest and fisher communities play an important role in conserving wild biodiversity. Approaches to managing agricultural landscape mosaics to minimize trade-offs and optimize synergies between agricultural livelihoods and biodiversity are emerging (or being recognized) in agroecosystems worldwide. These diverse approaches have come to be known collectively as ‘ecoagriculture’ (McNeely and Scherr 2003).
Which regions, and examples particularly are we talking about?
Out of this came ecoagriculture partners May 2001: Future Harvest – IUCN Collaboration on Agriculture & Biodiversity: “Common Ground, Common Future” (leading to 2003 book on ‘Ecoagriculture’) 2002: Consultations (New York, Montreal, Bali); Formed at Implementation Conference, WSSD Johannesburg February 2003: Strategic Planning Workshop, Gland, Switzerland (Co-sponsors: Forest Trends, IUCN, ICRAF) September 2004: International Ecoagriculture Conference, Nairobi
