On Farm

The community seed bank (CSB) is emerged as an effective rural institution at the community level to strengthen farmers’ access to diversity of crop genetic resources as well as seeds that contribute to local food security for poor farmers and also to ensure the conservation of agro-biodiversity on-farm. This paper presents some evidences from the community of western Nepal to demonstrate that CSB is one of the options to conserve and use agro-biodiversity on farm. Biodiversity Conservation and Development Committees (BCDCs) and farmers have established six CSBs in western terai with the support of Agrobiodiversity component of Western Terai Landscape Complex Project (WTLCP-ABD) in Bardia (1 CSB), Kanchanpur (2 CSBs) and Kailali (3 CSBs) districts. These CSBs are functional with prearranged community developed mechanisms for collection, conservation, replication and distribution of seeds. Communities have collected and conserved 88 (Belwa), 77 (Beldandi), 99 (Gadariya), 78 (Masuriya), 76 (Patharaiya) and 82 (Shankarpur) number of accessions of different crops in CSBs. CSB enhanced farmer’s seed system and strengthened social networks for exchange of seeds to cope with impacts of climatic adversity by providing immediate access to locally adapted germplasm as community based adaptation strategy. CSB is becoming a reliable local adaptation practice that minimizes the potential negative impacts of climate change in addition to accessibility, conservation and use of genetic resources in western terai of Nepal.

This chapter explores the current state of research, knowledge and practice of community-based conservation in the context of continued farmer-driven processes and the emergence of diverse external interventions. Autonomous community-based conservation is largely powered by farmer demand for crop diversity. Cultural, provisioning and regulating ecosystem services play an essential role. It is argued that an enhanced understanding of the drivers and rationales influencing farmers decision-making continues to be essential under the current scenario of accelerated global change. A large and diverse portfolio of exogenous interventions have emerged since on-farm conservation has become a development issue. A variety of different interventions designed to support on-farm conservation for are reviewed. This chapter also highlights the need for an effective monitoring framework for community-based management of crop genetic resources. Such a systems could enhance the measurement, metrics and intelligence underlying the on-farm conservation status of crops and landraces.

AbstractFarmers in local communities have a considerable amount of information on their genetic resources both at the individual and community level. The farmers' knowledge is interweaved into their daily practices as a reserve accumulated over the generations. The Farmer Field Fora approach (FFF) has been conceptualized in order to activate farmers to identify the existing resources both in the crops they cultivate and in their knowledge, to recognize its value and to start using it more consciously. The FFF approach links the use of existing diversity to the possibility of having new varieties and to improving productivity. In weekly meetings farmers observe changes in the field between varieties, debate on them and draw conclusions. In every session a theme on plant development is debated among farmers with the aid of a facilitator. Close contact with researchers allows involvement with the breeding practices and enables the aims and conduct used in research to be understood. This empowers farmers to participate in a more active way in research, to apply more precise ways of observing and managing their genetic resources, and to link their work to conservation activities at the national and local level. The results of the FFF trial, which was carried out in 10 villages in the region of San in Mali in 2001, show an increased interest among farmers to observe varieties. The appreciation criteria used is multiple including yield, earliness, strong tillers, high number of tillers, and resistance for diseases and Striga. It seems obvious that even though the goal of the approach is on-farm conservation of plant genetic resources, it must be closely linked to farmers' interest. The variation of the results between villages demonstrates variability of climatic condition in this region and a high genotype—environment interaction. Further modifications of the approach are required in order to improve equitable participation of different stakeholders and improve the institutionalization of on-farm conservation.

Agricultural biodiversity is the basis for agricultural research and development. This paper is based on the survey across the country along with the field implementation and action research on different conservation approaches over the years and locations. Management of agricultural biodiversity is being initiated in Nepal through ex-situ, on-farm, in-situ and breeding strategies by National Agriculture Genetic Resources Center (National Genebank) from 2010. National Genebank has implemented on-farm conservation across the country. Different approaches are community seed bank, community field genebank, household seed bank, household field genebank, village level field genebank and school field genebank. In addition to these, landrace enhancement program and recognition of agro-biodiversity rich farmers have also contributed on conserving APGRs. Identification of agro-biodiversity rich farmers have been initiated in collaboration with different governmental and non-governmental organizations across the country. Strong network among these farmers is supposed to establish for effectively managing APGRs on-farm. Agro-biodiversity conserved by such farmers is called household genebank, which consist of seed storage (household seed bank) and household field genebank. There are more than 100 CSBs in the country and some of them are conserving local genetic resources. Eight community field genebanks have been functionalized for conserving recalcitrant seeds and vegetatively propagated crop species. Village level field genebank has been established by NGO in Makwanpur district to conserve banana and taro. In this approach, different households grow different landraces, maintaining maximum diversity within a village. In some areas, school field genebank has been established by growing local APGRs in school areas. This helps to conserve APGRs, educate the students, earn the income and make environment beautiful. Genebank also encourages farmers to reintroduce the landraces from the National Genebank. Accessioning these APGRs and training to farmers and farming communities are necessary to effectively and efficiently conserving and utilizing APGRs on-farm.

Rice Diversity

Conservation of crop genetic resources presents a challenge of identifying specific determinantsdriving maintenance of diversity at farm and agroecosystems. The objectives of this study were toidentify socioeconomic, market and agroecological determinants of farmers’ maintenance of ricediversity at the household level and derive implications for policies in designing on-farmconservation programs. We assess spatial rice diversity at farm level using household surveydata. A household decision making model is conceptualised using microeconomic theory to assessand identify factors influencing on-farm rice diversity. The model is then tested econometrically byusing various factors affecting farmers’ variety choice and diversity decisions. The findings showthat household-specific socioeconomic, agroecological and market factors are important indetermining on-farm rice diversity. The significant variables in explaining richness and evenness ofrice diversity include distance to the nearest market, subsistence ratio, modern variety sold, landtypes and adult labour working in agriculture. The statistical signs of the factors determining ricediversity are consistent in explaining the richness, dominance and evenness among rice varieties.Finally, the study implies that the cost-effective means of promoting and sustaining on-farmconservation programmes is to target them in market isolated geographic locations of high cropdiversity where farm households have more heterogeneity of agroecological conditions and moreactive family adult labour working on-farm.Key words: Diversity indices; dominance; evenness; on-farm conservation; rice diversity; richnessDOI: 10.3126/narj.v6i0.3370Nepal Agriculture Research Journal Vol.6 2005 pp.49-5
