  4. Climate change is a phenomenon due to emissions of greenhouse gases from fuel combustion, deforestation, urbanization and industrialization (Upreti, 1999) resulting variations in solar energy, temperature and precipitation. Between 1970 and 2004 global GHGs emissions have increased by 70 %

  5. Livestock : GHG emissions N2O • Livestock  18 % of GHGs • The enteric fermentation of animals, • Manure (waste products), • Production of feed and forage (Dourmad et al., 2008). • Indirect sources : changes in land use and deforestation to create pasture land. CH4

  6. Climate change will have major impact on the people who depend on livestock for their livelihoods (Thornton et al., 2002).

  7. Climate Change and its Impacts in Nepal • Approximately 0.06 degrees Celsius per year. • Temperature in the Himalayas is increasing at a faster rate. • The Rika Samba Glacier in the Dhaulagiri region is retreating at a rate of 10m per year. • The AX010 Glacier of ShorongHimal will be extinct by 2060 if the current trend continues. • More than 40 Himalayan glacial lakes are dangerously closed to bursting (UNEP). • Rapidly melting glaciers means more seasonal variation in river flow water shortage, frequent floods and draughts in the country.

  8. Direct And Indirect Impacts On Livestock And Livestock Systems • Feeds: quantity and quality • Herbage growth and quality • Changes in composition of pasture • Changing concentration of water soluble carbohydrates and N at given dry matter yields • Lignifications of plant tissues

  9. …Impacts on livestock B. Heat stress : • Feed intake, mortality, growth, reproduction, maintenance and production • Increased energy deficits C. Water : • Water scarcity • Not only will affect livestock drinking water sources, but it will also have a bearing on livestock feed production systems and pasture yield (Thornton et al., 2008)

  10. …Impacts on livestock D. Livestock diseases and disease vectors • Vector-borne diseases could be affected by: (i) Expansion of vector populations into more temperate zones (such as livestock tick-borne diseases in higher altitude areas). (ii) Changes in rainfall pattern during wetter years, which could also lead to expanding vector populations and large-scale outbreaks of disease.

  11. …Impacts on livestock Livestock disease ….contd… • Helminthes infections. • Trypanotolerance- could be lost. • Distribution and impact of malaria in many systems. • Schistosomiasis and lymphatic filariasis in irrigated systems. • Heat-related mortality and morbidity could increase (Thornton et al., 2008).

  12. …Impacts on livestock E. Biodiversity • A 2.5° C rise in global temperature high risk of extinction. • Local and rare breeds could be lost

  13. Livestock Adaptation strategies Breeding strategies • Identifying and strengthening local breeds • Adapted to local climatic stress and feed sources • Heat tolerant breeds • Disease tolerant breeds • Improving local genetics • Cross-breeding

  14. …Adaptation strategies… Capacity building for livestock keepers • increasing awareness of global changes. training in agro-ecological technologies and practices for the production and conservation of fodder improves the supply of animal feed and reduces malnutrition and mortality in herds.

  15. …Adaptation strategies… Livestock management systems • Shade and water to reduce heat stress. • Reduction of livestock numbers – a lower number of more productive animals leads to more efficient production and lower GHG emissions from livestock production (Batima, 2007). • Changes in herd composition (selection of large animals rather than small) • Improved management of water resources (e.g. drip and sprinkler irrigation, store rainwater).

  16. Mitigation of livestock GHG emissions • Higher concentrate in the diet  lower the emission of CH4. • Management of animal waste products (covered storage facilities). • Pasture grazing through rotational grazing. • Management of feed crop production. • Selection of faster growing breeds. • Lowering livestock production and consumption

  17. Take-home messages • Participatory approaches to sustainable management of natural resources • Community involvement in adaptation strategies • Financial incentives • Risk management mechanisms • Awareness and education • Mitigation strategies • Innovation, research and technology development • Indigenous knowledge
