Enhancing the in situ management of agricultural biodiversity A proposal for Strategic Research Theme 5 of CRP 1.1
Rationale Genetic diversity still being lost In situ offers benefits of dynamic evolution and indigenous knowledge Currently undervalued, and hence underused Genetic resources and information vital for future agricultural development and access to these resources is essential
Objectives & Long-term Impacts Target agrobiodiversity better managed, understood, conserved and used in agreed high priority geographical areas (global). Information gathered and made available. Policy environment supportive for management and use and access facilitated. Impact pathway is same as for ex situ conservation Long-term impacts: Food and nutrition security Ecosystem services and sustainability
Research Topics 1. Status and trends of target crops and species 2. Target species in systems: Development of in situ and on farm conservation approaches, tools and methodologies 3. Facilitating use of target crops and species 4. Information and knowledge supporting in situ conservation and management 5. Policy and strategies to support the in situ management and access to and availability of agricultural biodiversity
Important role of women Focus on gender in design and implementation of research methodologies, and compilation and sharing of knowledge on role of women as custodians of diversity Role of women disaggregated for Management of on-farm diversity Conservation decisions Use values, characterization Traditional knowledge
Capacity strengthening Enhance individual capacities for R&D and influence institutional capacities for mainstreaming research results from local to regional levels Capacity strengthening Women empowered to use on farm diversity Farmers as data providers and users Policy implementation
Linkages with CRPs CRP 1.1 Links with other components Capacity development Reducing vulnerability & risk Enhancing resilience Sustainable intensification, participatory breeding Policy outputs will help SRT2 and SRT3 M&E and IA for arid sites in concert with SRT4 CRP1.2 and 1.3 Share study sites, focus areas
Linkages with CRPs CRP2 Link target agrobiodiversity to value chain analysis CRP3 Use of landraces and CWR for crop improvement CRP4 Target biodiversity used to improve health and nutrition CRP5 Importance of target biodiversity in providing ecosystem services CRP6 Sharing methodologies for in situ conservation CRP7 Use of target biodiversity for adaptation and mitigation
Partnerships With regional fora initiatives on agrobiodiversity FARA: Agrobiodiversity initiative for Africa APAARI: Implementation of Suwon declaration on ABD ARINENA: Regional strategy for PGR conservation Development partners (e.g. LI-BIRD, MSSRF, PROINPA) Research partners Agropolis, USDA NBPGR, EMBRAPA, CAAS FAO, CBD, IUCN, CI
Governance Integral part of CRP1.1 using same governance and management structures Outside dry areas will work closely with CRP1.2 and CRP1.3 To be further discussed

Example: rice in Vietnam Collection of same varieties in 1986, 1991 and 1997. Area has undergone agricultural intensification, including increased irrigation and market orientation. Farmers started to select for certain traits.
Later planting leads to selection for later maturing (less photoperiodic) rice Flowering date of ex situ (1986 and 1991 collections) and in situ (1997) of each of the seven varieties. Number of days from seeding to date of 50% flowering.
Irrigation leads to selection against drought tolerance Number of surviving plants after the drought stress for ex situ (1986 and 1991 collections) and in situ populations (1997) of each of the seven varieties.
Agricultural Biodiversity Diversity that contributes directly and indirectly to food production, including livestock, pollinators, microbes, etc. Proposal focuses on genetic diversity of farmer- maintained Local livestock breeds, Varieties and landraces of major crops and their wild relatives, Neglected and underutilized species, Rangeland species.
