A major objective of in situ conservation strategies is to maintain evolutionary processes. In situ conservation of crop plants involves the conservation on-farm of local crop cultivars or landraces with the active participation of farmers and is also a powerful strategy to integrate farming community into the national PGR system so that monitoring of genetic resources could be done at local scale. In situ conservation strategies also promote a broader range of partnerships in conservation efforts as it involves diversity of stakeholders and objectives. It In order to maintain and use landraces for sustainable manner, landrace must be competitive with other options a farmer might have and contribute to the food security and possible increase in a farmer’s income. Many projects fail to involve community in on-farm conservation projects. The poster documented the general process of implementation of the IPGRI’s Global in situ conservation projects in Nepal and Vietnam. Often participatory entries points for local cultural and government policy context are limited for effective implementation of on-farm conservation which involves diverse farmers, local institutions and agricultural extension and research systems. A number of participatory tools such as diversity fair, diversity kits, diversity block, CBR and PPB strengthen local capacity to develop on-farm conservation strategies at local level and contribute to the improvement of farmers’ livelihoods. This can only be achieved through long term commitments from the International Undertakings, donors and government policies besides national and local efforts The paper discusses the steps and methods used on in situ conservation of agricultural biodiversity on-farm. Some of the major results, constraints, impact and future directions and recommendations are also discussed.
