  1. THE ETHIOPIAN CASE ON SUSTAINABLE USE OF AGRICULTURAL BIOLOGICAL RESOURCES

  2. WHAT ARE BIOLOGICAL RESOURCES? Biological resources refer to the living landscape—the plants, animals, and other aspects of nature and are important to society for the various services they provide, as well as problems they may create.

  3. Biological resources are grouped into those: • that affect agriculture, such as cultivated plants, pollinators, and pests; • those that are sources of scientific inputs, such as agricultural plant varieties (and their wild relatives) • those that provide genetic resources; and • those that provide natural goods and services, such as wildlife, fish, and scenic beauty

  4. Biological resources are fundamental to: • agriculture • livestock • logging • export earning • medicinal resource, and • provides free of charge services

  5. These services include: • clean water • pure air • soil formation and protection • pollination • crop pest control and • the provision of foods, fuel, fibres and drugs

  6. WHAT IS BIODIVERSITY? Biological diversity or “biodiversity” has been defined by the Convention on Biological Diversity (CBD) as: “the variability among living organisms from all sources including inter alia, terrestrial, marine and other aquatic ecosystems and the ecological complexes of which they are parts; this includes diversity within species, between species, and of ecosystems”

  7. BIODIVERSITY AND ITS IMPORTANCE The sustainability of ecosystem depends to a large extent on the buffering capacity provided by having a rich and healthy diversity of genes, species and habitats. Losing biodiversity is the same as losing the life support system that we and other species depend upon

  8. ECOSYSTEM DIVERSITY IN ETHIOPIA Ethiopia with its geographical position, between 3o and 15oN latitude and 33o and 48oE longitude covers a land area of 1,127,127 km2. The Great Rift Valley cuts diagonally across the country from Red sea to Kenya, creating a vast depression. It is a country of great geographical and climatic diversity

  9. Major ecosystems of Ethiopia • Afroalpine and sub-afroalpine Ecosystem • Dry Evergreen Montane Forest and Grassland complex • Moist Evergreen Montane Forest Ecosystem • Acacia-Commiphora Woodland Ecosystem

  10. Combretum-Terminalia Woodland Ecosystem • Lowland, Semi-evergreen Forest Ecosystem • Desert and Semi desert Scrubland Ecosystem • Aquatic Ecosystem

  11. PLANT GENETIC RESOURCES DIVERSITY • The genebank, since its establishment, has mounted a series of plant exploration and collection expeditions to collect and conserve the diversity in crop plants occurring in Ethiopia. In general, currently the Institute holds ca 60,000 accessions of some 104 plant species obtained through collection, repatriation and donation.

  12. A great portion of the material has been evaluated for various characteristics at appropriate agro-ecological sites. The material collected over the years is being conserved using appropriate conservation practices depending on the storage behaviour, type and the nature of the species. The bulk of the collected material is principally cereals and pulses, among others. 

  13. FIELD CROPS GENETIC RESOURCES DIVERSITY Ethiopia is known to be a center of origin and diversity for many cultivated crop plants. It is a primary gene center for field crops such as Niger seed (Gastonia abyssinica), Tef (Eragrostis tef) and Ethiopian mustard (Brassica carinata) and a secondary gene center for crops such as Durum wheat, Barley, Sorghum, Finger millet, Linseed, Sesame, Safflower, Faba bean, Field pea, Chickpea, Lentil, Cowpea, Fenugreek and Grasspea.

  14. Community based in situ conservation initiative A project entitled ‘A Dynamic Farmer Based Approach to the Conservation of Ethiopia’s Plant Genetic Resources’ funded by the Global Environment Facility (GEF) was initiated in 1994 addressing a neglected aspect of plant diversity that of indigenous crop varieties maintained by farmers in dynamic agro-ecosystems.

  15. This community-based in situ conservation project is designated to link farming communities and their varieties with the existing formal genetic resources conservation efforts of the IBCR by means of establishing community gene banks. Conservation at the farm level allows for continuing farmer selection, interaction with the environment and gene exchange with the wild species so that evolution of landraces may continue. 

  16. In this project, twelve on-farm in situ conservation sites and community gene banks have been established for farmers' varieties in six agro-ecological regions. Farmer Conservator Associations have been formed for each in situ conservation site. Agro-morphological, nutritional, biochemical and ethnobotanical studies were conducted on some of the crop species under in situ conservation.

  17. Crop germplasm samples originally collected from the in situ sites and maintained at the genebank were also restored at their respective sites. Indigenous knowledge of the farmers on their crop cultivars such as methods of selection, cultivation and use of different crops and cultivars, women’s knowledge and role, seed exchange and movement were surveyed and documented.
