Livestock and the rangeland commons in South Africa's land and agrarian reform

Journal Articles & Books
Décembre, 2013
Afrique du Sud
Afrique australe

Land and agrarian reform has the potential to expand South Africa's rangeland commons and enhance their contribution to the livelihoods of the rural poor, yet to a large extent this has been an opportunity missed. Shifting policy agendas have prioritised private land rights and commercial land uses, seeking to dismantle the racial divide between the white commercial farming areas and the ex-Bantustans by allocating former white farms to black farmers. These agendas and planning models reflect class and gender bias and a poor understanding of common property.

Institutions and governance of communal rangelands in South Africa

The creation of local institutions with a mandate over land access and control is seen as a prerequisite for successful decentralisation of land tenure and effective local resource management in sub-Saharan Africa. However, with land tenure reform in South Africa currently at a state of legislative impasse, real uncertainty now exists over land rights and governance of rangeland in many communal areas.

Resolving Range Conflict in Nevada? Buyouts and Other Compensation Alternatives

Journal Articles & Books
Décembre, 2006

To mitigate the adverse effects of reduced access to public forage, ranchers may require financial or other forms of "compensation." In this paper, we use results from a survey of Nevada ranchers to examine their willingness to sell grazing permits and participate in other schemes that enable them to continue ranching in spite of declining access to public forage.

Trends in productivity of crops, fallow and rangelands in Southwest Niger: Impact of land use, management and variable rainfall

Journal Articles & Books
Décembre, 2009
Niger

To document trends in land use and herbaceous production, 71 field sites sampled among cropped fields, fallow fields and rangelands in the Fakara region (Niger) were monitored from 1994 to 2006. The overall trend in land use confirmed the historical increase of the cropped areas since mid 20th century, at an annual rate of 2% from 1994 to 2006. This trend is the result of changes in the relative extent of fields permanently cropped and fields under shifting cultivation, and for the latter, the relative proportion of short (3 years) and long (10 years) duration fallows.

Land use, rangeland degradation and ecological changes in the southern Kalahari, Botswana

Journal Articles & Books
Décembre, 2016
Botswana

Dual‐scale analyses assessing farm‐scale patterns of ecological change and landscape‐scale patterns of change in vegetation cover and animal distribution are presented from ecological transect studies away from waterpoints, regional remotely sensed analysis of vegetation cover and animal numbers across the southern Kalahari, Botswana. Bush encroachment is prevalent in semi‐arid sites where Acacia mellifera Benth. is widespread in communal areas and private ranches, showing that land tenure changes over the last 40 years have not avoided rangeland degradation.

Formalizing expert judgements in land degradation assessment: a case study for Ethiopia

Journal Articles & Books
Décembre, 2003
Éthiopie

Expert judgements are potentially a valuable source of information in land degradation assessment, especially in areas where data paucity impedes the use of quantitative models. However, expert opinions are also much disputed because they are not tested for consistency, abstain from formal documentation, while their quantitative interpretation is inherently unidentifiable. This paper evaluates and formalizes the use of expert judgements to conduct a nationwide water erosion hazard assessment in Ethiopia.

Modeling for Prediction of Land Cover Changes Based on Bio-physical and Human Factors in Zagros Mountains, Iran

Journal Articles & Books
Décembre, 2013
Iran

The rapid population growth and ongoing development activities has resulted in natural resources demolition. However, the dynamics of the natural resources in relation to different biophysical and socio-economic factors are still remains poorly understood. The present study investigates the basic natural resources i.e. forest, rangeland and surface water bodies’ status using satellite data for the years 1990, 1998, and 2006, and their change detection in relation to biophysical and socio-economic factors.

Successful Adaptive Management - The Integration of Research and Management

Journal Articles & Books
Décembre, 2006

Adaptive management is a way for managers to do their jobs in the face of uncertainty and learn by doing. Managers gain greater knowledge of their systems by testing different strategies during the management process. The term “adaptive management” is used often, but there is confusion about exactly what adaptive management is, and managers are hard-pressed to find any clear guidelines for implementing it.

effects of a deferred grazing system on rangeland vegetation in a north-western, semi-arid region of Tanzania

Tanzania

The present study assessed the effects of deferred grazing management on rangeland condition using aboveground biomass, vegetation cover and species composition as indicators of range condition. The experiment was based on traditionally conserved exclosures (ngitili). Data were collected in Shinyanga rural and Meatu districts, Tanzania, from October to November 2011. Five grazing strategies were compared: old private ngitili , young private ngitili , old communal ngitili , young communal ngitili and continuously grazed land.

Willow cover as a stream-recovery indicator under a conservation grazing plan

Journal Articles & Books
Décembre, 2012

Many rangeland streams and associated fisheries have suffered from livestock grazing as a cost of upland-forage utilization. Due to damage from intensive usage, restoration of damaged streams is now a common land-management objective. The Squaw Valley Ranch of Elko County, Nevada, US, in cooperation with the US Bureau of Land Management (BLM) and Barrick Gold Corp., is attempting to improve those portions of the Rock Creek watershed negatively affected by past ranch operations.

effect of development interventions on the use of indigenous range management strategies in the Borana Lowlands in Ethiopia

Journal Articles & Books
Décembre, 2008
Éthiopie

In the last three decades, the Borana rangelands of Southern Ethiopia have been deteriorating due to unsustainable utilization. This paper analyses the changes in indigenous range management among the Borana pastoralists and the role of development interventions.The fieldwork was carried out during 2000-2002, following a severe drought. Two locations, Dida Hara and Web, that once were part of a large grazing system with seasonally distinct herd movements, experienced differences in development interventions.
