  • Abby: please creat title slide with an image of either: 1) agricultural biodiversity – e.g., 50 varieties of maize or apples displayed – not potatoes, as we use that example later; or 2) a clearly diversified farming plot, but not agroforestry – e.g., google permaculture

    1. 1. Landscape Approaches toAgrobiodiversity Conservation and UseDunja Mijatovic, Yasuyuki Morimoto, Patrick Maundu, NadiaBergamini, Devra Jarvis and Pablo EyzaguirreBioversity International Photo: USDA
    2. 2. A Global Review:• Presenting evidence, examples and key concepts. Bioversity International’s research sites• Interdisciplinary approach: bringing together findings from the fields of conservation biology, ecology, ethnobotany and anthropology.• Meta-analysis of Bioversity International’s in situ conservation projects’ outcomes. Farm fields: 24 crops Fruit tress in Central Asia Crop wild relatives Home gardens Date palm in North Africa Tropical fruit trees in Diversity for pest and Bananas in East Africa South-East Asia disease mitigation Landscape mosaics
    3. 3. A landscape perspective on agrobiodiversity • Agrobiodiversity as an emergent property of the intended and unintended effects of human actions that lead to modifications or transformations of landscape and ecological relationships (Howard 2010). • Agricultural resilience and sustainability as a function of beneficial links between different agrobiodiversity components (pollinators, soil biota, tree species) at a landscape scale.

    5. 5. Why a landscape approach to conservation? Agrobiodiversity in a changing landscapeMaintaining the diversity of landscapes, agro-ecosystems, speciesand varieties to sustain adaptation:• Natural and cultural selection (diverse niches, multiple uses)• Seed flow (informal exchange networks)• Domestication (wild fruit tree species)• Gene flow (cross-pollination)• Crop wild relatives (stress-resistance)• Innovation

    7. 7. Maintaining agricultural biodiversity in mosaic landscapes for continued evolution and adaptation, sustainability and resilienceLandscape approach to agrobiodiversity conservation and use: • Conserving agrobiodiversty (plants, animals, pollinators, soil biota, crop wild relatives) at various scales (from genetic to landscape level); • Sustaining evolution and adaptation processes that maintain and generate diversity; • Encouraging the use of agrobiodiversity and innovation to enhance resilience and sustainability; • Empowering local communities and strengthening their role as innovators and custodians of genetic resources.
