PPT On Climate Change
Description:1.IMPACTS OF CLIMATE CHANGE ON LIVESTOCK AND MITIGATION STRATEGIES
Specific atmospheric trend and pattern of particular place determined by the interaction of Atmospheric elements
3. Climate Change
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.
4.Livestock : GHG emissions
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.
5.Climate change will have major impact on the people who depend on livestock for their livelihoods (Thornton et al., 2002).
6. 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 Shorong Himal 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.
7.Direct And Indirect Impacts On Livestock And Livestock Systems
Feeds: quantity and quality
Herbage growth and quality
Changes in composition of pasture
of water soluble carbohydrates
and N at given dry matter yields
Lignifications of plant tissues
8.B. Heat stress :
Feed intake, mortality, growth, reproduction, maintenance and production
Increased energy deficits
C. Water :
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)
9.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.
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).
A 2.5° C rise in global temperature
high risk of extinction.
Local and rare breeds could be lost
12.Livestock Adaptation strategies
Identifying and strengthening local breeds
Adapted to local climatic stress and feed sources
Heat tolerant breeds
Disease tolerant breeds
Improving local genetics
13.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).
14.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
Participatory approaches to sustainable management of natural resources
Community involvement in adaptation strategies
Risk management mechanisms
Awareness and education
Innovation, research and technology development
