Why Livestock Production isImportant ?

Occupy 30% of the planets ice free terrestrial surface area;

Significant global assets with a value of at least 1.4 trillion USD

Globally contribute 40% of GDP, in Bangladesh 33%of AgriculturalGDP and

From Nutritional stand point, 30-50%of proteins to human diet

Back bone of Agriculture providing adding value to cropproduction

Employ 1.3 b people globally, 600 m poor small farmers indeveloping world, 10 million direc tly in Bangladesh

4/10

Impact of Climate Change onLivestock Production- Temperature tolerance of heat waves;

Heat stress,

Possible reduction in feed sources,

Extreme events- Climate Variability;

Mateo-patty (rapid air pressure change),

Excited behavior- (storm, surge, together makes an onslaught),

Sea level rise triggers spatial dimension (13-17% land loss),

Compound other stresses upon Agricultural production.

Decrease production;

5oC increased up to 10% lower productivity,


5/10

Impact of Climate Change onLivestock Production-

Feed availability; Land use and systems change,

Changes in primary productivity- crops, forages,

Changes in species composition,

Quantity and quality of plant material i.e., pasture loss

Disease vectors;

Spatial and temporal dimension of diseases vectors

Tropical diseases vectors occurred;

Toxin in feed , food


6/10

Consequences-Cattle production

Dairy- high negative

Intensive forage production

High productive breeds

Low climate variability tolerance

Beef- low negative

Natural pastures,

Locally adapted breed (e.g., RCC)


7/10

Consequences-small ruminantproduction

Sheep and goat- low negative/positive

Extensive traditional,

Natural pastures (under grazing),

Locally adapted breeds,

Soc io-economic impact is significantly bigger,

Disease control (parasites, helminth infection etc.,)


8/10

Consequences-Poultry and pigproduction

High negative;

Intensive production,

High efficient genetic resources,

Low adaptability on diverse conditions,

Required high quality feed,

High investment in controlled indoor environment,

Decreased economic efficiency.


9/10

Cope with Climate Changes inLivestock sector

Controlled environment in the barns;

Thermal isolation,

Cooling installments (Spraying, chillers ---),

Water treatment.

Feeding efficiency;

Intensive production

Pastures management

Genetic perspective;

Animal genetic resources loss,

Climate variability tolerance animals are required.


10/10

What More Options left ?

Adaptive research;

Work on development of locally adapted breeds;

Investment in adaptation, that we are week;

Systematic approach;

Assessment CC on animal health; relationship between CC &animal health;

Modelling climate related changes to grassland/ forageproduction;

Develop an impact inventory across livestock spec ies and theirvalue in monetary terms;

Disease control and prevention;

Carry out a cost benefit appraisal of adaptation plans.
