Impacts of climate change on livestock and mitigation strategies

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 %


Livestock ghg emissions

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


Impacts of climate change on livestock and mitigation strategies

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


Climate change and its impacts in nepal

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 flowwater shortage, frequent floods and draughts in the country.


Direct and indirect impacts on livestock and livestock systems

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


Impacts of climate change on livestock and mitigation strategies

…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)


D livestock diseases and disease vectors

…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.


Livestock disease contd

…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).


E biodiversity

…Impacts on livestock

E. Biodiversity

  • A 2.5° C rise in global temperature

    high risk of extinction.

  • Local and rare breeds could be lost


Livestock adaptation strategies

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


Capacity building for livestock keepers

…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.


Livestock management systems

…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).


Mitigation of livestock ghg emissions

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


Take home messages

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
