Importance Of Livestock Production From Grasslands For National And Local Food And Nutritional Security In Developing Countries, Iain A. Wright
Importance Of Livestock Production From Grasslands For National And Local Food And Nutritional Security In Developing Countries, Iain A. Wright
IGC Proceedings (1997-2023)
Grazing lands cover more than a quarter of the world’s land surface, often on land that is unsuitable for other forms of use. Despite the perception that productivity is inherently low, the contribution of grasslands in food security in developing countries is significant. However the challenges of spatial and temporal variability of primary productivity need to be managed and mobility of livestock is key to this. Appropriate land management and governance arrangements are essential for facilitating this mobility and for creating the circumstances in which technical options for reducing variability and risk in livestock keeping can be deployed and to …
Changing Grassland Scenario In Developing Countries--Economical And Social Perspective, Abule Ebro
Changing Grassland Scenario In Developing Countries--Economical And Social Perspective, Abule Ebro
IGC Proceedings (1997-2023)
Grasslands are mainly used for livestock production in developing countries although they have been facing contradictory pressures, i.e., increased demand for natural resources and animal products to cope with rising human populations. On the other, there is a need to preserve the environment and ecosystem. This paper reviewed the causes of grassland changes, the economic and social perspective of changing grasslands with more emphasis on dry lands. Different indicators were used to assess the economic (livestock production, wildlife and tourism, crop production, ecosystem services) and social (traditional institutions, mobility, land tenure and grazing systems) perspectives of changing grassland. The major …

Ecologically And Socially Sustainable Livestock Development In Marginal Areas, Ilse Köhler-Rollefson
IGC Proceedings (1997-2023)
“Marginal areas” are perceived as difficult and unproductive landscapes, always under the threat of drought, desertification and poverty. Yet, both dryland and high altitude marginal areas have an extraordinary output of livestock products; in the efficiency of producing human-edible protein they far surpass more fertile areas. This productivity under adverse climatic conditions rests on sophisticated strategies and social institutions developed by pastoral communities to deal with variability in the availability of resources. It depends on the use of animal genetic resources that are adapted to make best use of local vegetation and can cope with seasonal variations in availability. Livestock …
