  1. 1. Participatory Four cell analysis For Understanding Local Crop Diversity Rachana Devkota EDRD 6000 Qualitative Research Methods School of Environmental Design and Rural Development University of Guelph, 2016
  2. 2. Four cell analysis (FCA)  Participatory method to assess on-farm diversity status  Rapid community assessment technique to assess the amount and distribution of crop diversity within farming communities Purpose  To measure the abundance (richness) and distribution (evenness) of local crop diversity  To identify common, unique and rare/endangered varieties or species  To understand and document reasons why each variety is in a dynamic state within a community and to enhance knowledge for potential intervention Photo: Four cell analysis in Sri Lanka, 2010
  3. 3. Why Four Cell Analysis is needed?  Farmers throughout the world have continued to maintain and manage substantial crop diversity in agricultural production systems.  Diverse crop varieties constitute a conspicuous source of variation and provide valuable genes and characteristics for crop improvement.  Understanding of amount and distribution of local crop diversity at the community level is basic information required for managing agricultural biodiversity on-farm.  Farmers possess an intricate understanding of the crops and crop varieties they grow and they use distinct local names according to characteristics of varieties to identify diversity changes over time and space, which is often not measured.  Suitable participatory methodologies that help researchers and farmers to understand distribution patterns of local crop diversity and reasons or such distribution are lacking (Sthapit et. al., 2006).  The Four Cell Analysis method is first developed by the in-situ project team (Bioversity International, Ministry of Agriculture and Development and LI-BIRD) in Nepal in 2000.
  4. 4. When to use the Four Cell Analysis?  To identify which species or varieties are found in the community and which species or varieties are common, unique and rare.  To identify the abundance, distribution and spread of the crop varieties in terms of richness, evenness and divergence at community level.  To document the key characteristics and reasons why crop species or varieties are in a certain dynamic stage, regarding their abundance and distribution within the community.  To identify the potential interventions for the conservation and/or promotion of a crop species or variety within a specific community.  When repeated over time, it gives insight in the rate of loss of diversity in that specific area.
  5. 5. How to do Four Cell Analysis?  Identify 6-12 key informants with knowledge of growing crop in the community for the focus group discussion.  Ask farmers to bring samples (seed/leaf/any product) of each variety that they are growing.  Prepare a list of farmers’ varieties of selected crops through discussion.  Make a large cross on the ground/paper/board and distinguish the four categories or squares.  The meaning of the four squares are visualized by drawing different numbers of houses and large or small fields.
  6. 6. How to do Four Cell Analysis?  The following questions are asked to the participants to get information on varieties/crop species (name, specific traits, origin) • What varieties/crops are cultivated in large areas by many households? • What varieties/crops are cultivated in large areas by few households? • What varieties/crops are cultivated in small areas by many households? • What varieties/crops are cultivated in small areas by few households?  Ask for every variety/species, why it was placed in that specific cell? For example • Why variety/species A is found only in small number of trees/area and used only by few households? • Which traits, uses or reasons are responsible for this current status? • Which varieties/species are rare/unique and should be prioritized for conservation or promotion? • Which potential interventions could be initiated to conserve and/or promote these varieties or species?
  7. 7. FCA Result analysis and community planning  The participating group discusses the result.  Varieties which fall into four different cells may have one of the following rationales; Many Households Few Households Large area varieties grown for food security or for the market or with multiple use values (common) Varieties that are newly introduced or with specific adaptations traits (such as cultivars adapted to swampy lands, poor soil fertility, drought, shade etc.) (Unique and vulnarable) Small area Varieties cultivated for socio-cultural (traditions, religious rituals, food culture) purposes (Unique and vulnarable) varieties with specific uses or limited use value to particular families (rare and under threat)
  8. 8. Germplasm enhancement, Participatory plant breeding, Value addition, Market links, Recognition, Awareness Seed stored in Community seed bank, can be grown in Diversity blocks On-farm conservation of the seed/crop (Common) Deployment to similar niches for seed production Figure: The four-cell analysis for community based on-farm conservation actions  Identify common and rare types of diversity within the community and facilitate both developmental as well as conservation action plan (see figure).  For example: Discuss with community how they wish to maintain rare varieties. If nobody wants to grow a variety then it should be sent to ex situ conservation. FCA & Community planning Source: Sthapit et al., 2006
  9. 9. Outcome of using Participatory FCA  Documentation of the key reasons why varieties are in a certain dynamic stage  Empowering the farming communities by enabling self directed conservation and development action plans  Making farming communities aware of the threat of genetic erosion  Identifying potential interventions within a community
