The concept of rangeland carrying capacity in sub-saharan Africa: Myth or reality?

Diciembre, 1989
África subsahariana

Ever since colonial administrators and western trained scientists became involved in sub-Saharan Africa in the early 20th century and were faced with the task of governing countries where livestock production was a major economic enterprise, the proper utilisation of rangelands became a major concern. While during most of the colonial era devastating epidemics (like rinderpest and pleuropneumonia) kept the growth of livestock populations in check, during the 1950s and 1960s regional campaigns of eradicating these major cattle diseases created a continuous increase in livestock numbers.

Planting the foundations of a post-2020 land sector reporting and accounting framework

This paper presents possible elements of a long-term international vision for land sector reporting and accounting. The vision is of a multi-dimensional land sector reporting and accounting framework that is applicable to all countries and increases in comprehensiveness over time. The overarching objective of the framework is to build trust between Parties to the United Nations Framework Convention on Climate Change (UNFCCC) by tracking progress in implementation of mitigation contributions in the land sector.

Land valuation and perceptions of land sales prohibition in Ethiopia

Diciembre, 2013
Etiopía

This study investigates attitudes towards legalizing land sales and Willingness to Accept (WTA) sales prices and compensation prices for land among smallholder households in four different areas in the Oromia and SNNP Regions in the southern highlands of Ethiopia.

Household panel data from 2007 and 2012 are used. The large majority of the sample prefers land sales to remain illegal, and the resistance to legalizing land sales increased from 2007 to 2012. In the same period, perceived median real land values increased sharply but also exhibit substantial local variation.

Tribes, state, and technology adoption in arid land management, Syria

Diciembre, 2000
Siria
Asia occidental
África septentrional

Discusses the widely help conception that arid shrub-lands in Syria and elsewhere in West Asia and North Africa are degraded. A particular characteristic of such areas is a preponderance of unpalatable shrubs or a lack of overall ground cover with a rise in the associated risks of soil erosion.The article finds that:migrating pastoralists have been the scapegoats for this condition of the range.

A review of changes in rangeland vegetation and livestock populations for Northern Kenya

Diciembre, 1998
Kenya
África subsahariana

This review explores environmental change in northern and south-central Kenya, roughly covering three decades from the 1960s to the 1990s. The report answers three questions:has vegetation change occurred in these districts?if vegetation change has occurred, why and how has this happened?what are the trends for livestock populations?The article concludes that:rangeland sites have been fundamentally altered by woody encroachment over the past 40 years.

Land grabbing under the Cover of Law: Are BRICS-South relationships any different?

There is a general consensus among academics, politicians and social movements, that BRICS as ‘new donors’ are increasing both their quantitative and qualitative role in defining what is considered to be ‘the world economic order’.

Carbon, land and water: a global analysis of the hydrologic dimensions of climate change mitigation through afforestation / reforestation.

América Latina y el Caribe
Asia occidental
América Septentrional
África septentrional
Asia oriental
Oceanía
Asia meridional

This report highlights the potentially significant impacts on the hydrologic cycle and the importance of considering secondary effects, particularly with regard to water, resulting from the widespread adoption of global climate change mitigation measures. It is recommended that the implicit hydrologic dimensions of climate change mitigation should be more formally articulated within the international environmental conventions, and recognized within future UNFCCC negotiations on the CDM-AR provisions.

Forests and climate change: role of forest lands as carbon sinks

Diciembre, 1996

Forests potentially contribute to global climate change through their influence on the global carbon (C) cycle. They store large quantities of C in vegetation and soil, exchange C with the atmosphere through photosynthesis and respiration, are sources of atmospheric C when they are disturbed, become atmospheric C sinks during abandonment and regrowth after disturbance, and can be managed to alter their role in the C cycle. The world's forest contain about 830 Pg C (1015 g) in their vegetation and soil, with about 1.5 times as much in soil as in vegetation.

Across vast areas of the world, human activity has degraded once fertile and productive land. Deforestation, overgrazing, continuous farming and poor irrigation practices have affected almost 2 billion hectares worldwide, threatening the health and livelihoods of over one billion people. In this edition of New Agriculturist, a collection of articles explores some of the approaches and policies that can help to successfully rehabilitate degraded land.
