Opportunities for fire and carbon on pastoral properties in the savanna rangelands: perspectives from the Indigenous Land Corporation and the Northern Territory Cattlemen’s Association

Journal Articles & Books
Diciembre, 2014
Australia

Understanding both the carbon dynamics within Australia’s northern savannas and the opportunities presented through diversification into carbon markets is of relevance to pastoral land managers both in Australia and globally. The Indigenous Land Corporation (ILC), through its role in assisting Indigenous people to acquire and manage land for cultural, social, environmental and economic benefits, has operated in the carbon market and is keen to continue working with its partners to explore the opportunities to develop and broaden this further.

Methods for improving rangelands in the Blacksea region of Turkey

Policy Papers & Briefs
Diciembre, 2008
Turquía

The objective of this study was to determine the most suitable method (or methods) to improve in the rangelands around Samsun-Turkey rangelands between 1993 and 1999. The 12 management treatments in this study included control, aeration, burning, herbicide application, fertilization, over-sowing, ploughing + resowing and a combination of all the treatments. A mixture of seeds consisting of alfalfa, sainfoin, smooth bromegrass, orchardgrass and blue wheatgrass was used for oversowing and in the ploughing + resowing plots.

Determinants of food security under changing land-use systems among pastoral and agro-pastoral households in eastern Ethiopia

Journal Articles & Books
Diciembre, 2015
Etiopía

A number of previous studies have emphasized the determinants of land-use change, as well as the management of communal lands in the pastoral systems, without assessing the effects of such changes on pastoralists/agro-pastoralists’ food security. Therefore, the objective of this paper was to assess the determinants of food security under changing land use and land management systems—from communal to private investment—using household survey data collected from pastoral and agro-pastoral communities. The data were analyzed using ordinary least-square econometric analysis.

Soil carbon and nitrogen across a chronosequence of woody plant expansion in North Dakota

Journal Articles & Books
Diciembre, 2010
América Septentrional

Woody plant expansion has been documented on grasslands worldwide as a result of overgrazing and fire suppression, but changes in ecosystem structure and function accompanying this phenomenon have yet to be extensively studied in the temperate semi-arid grasslands of North America. The primary objectives of this study were to determine the influence of woody plant expansion on soil carbon (C), soil nitrogen (N), and roots to a depth of 15 cm along a 42-year (1963-2005) chronosequence encompassing grassland, woodland, and transition zones in a northern Great Plains grassland.

Understanding Variability in Adaptive Capacity on Rangelands

Journal Articles & Books
Diciembre, 2013

The art and science of developing effective policies and practices to enhance sustainability and adapt to new climate conditions on rangelands and savannas are typically founded on addressing the “average” or “typical” resource user. However, this assumption is flawed since it does not appreciate the extent of diversity among resource users; it risks that strategies will be irrelevant for many people and ignored, and that the grazing resource itself will remain unprotected. Understanding social heterogeneity is vital for effective natural resource management.

Monitoring the status of forests and rangelands in the Western United States using ecosystem performance anomalies

Journal Articles & Books
Diciembre, 2013
Estados Unidos de América

The effects of land management and disturbance on ecosystem performance (i.e. biomass production) are often confounded by those of weather and site potential. The current study overcomes this issue by calculating the difference between actual and expected ecosystem performance (EEP) to generate ecosystem performance anomalies (EPA). This study aims to delineate and quantify average EPA from 2000–2009 within the Greater Platte and Upper Colorado River Basins, USA.

Soil seed bank evaluation along a degradation gradient in arid rangelands of the Somali region, eastern Ethiopia

Journal Articles & Books
Diciembre, 2009
Etiopía

The potential and regeneration capacity of soil seed banks in three eastern Ethiopian rangeland ecosystems (Asbuli grassland or arid grassland, Aydora open savanna or arid bush/grassland and Hurso closed savanna or arid bush land) were determined over a degradation gradient. Soil samples from 0.09m² blocks (100mm deep) were spread evenly in plastic containers in the greenhouse and studied over a 1-year period. The aboveground species composition was also compared. Sampling was from rangelands in excellent, good, moderate and poor conditions for each ecosystem.

Grazing impacts on the susceptibility of rangelands to wind erosion: The effects of stocking rate, stocking strategy and land condition

Journal Articles & Books
Diciembre, 2015
Australia

An estimated 110 Mt of dust is eroded by wind from the Australian land surface each year, most of which originates from the arid and semi-arid rangelands. Livestock production is thought to increase the susceptibility of the rangelands to wind erosion by reducing vegetation cover and modifying surface soil stability. However, research is yet to quantify the impacts of grazing land management on the erodibility of the Australian rangelands, or determine how these impacts vary among land types and over time.

Assessing gender roles in a changing landscape: diversified agro-pastoralism in drylands of West Pokot, Kenya

Journal Articles & Books
Diciembre, 2015
Kenya

Previous studies in drylands have shown that while gender roles are becoming more flexible, privatization and formalization of land tenure tends to marginalize women in drylands while environmental degradation leads to differential changes in gender workload. Chepareria, a ward in West Pokot County, has undergone the above-mentioned tenure and environmental changes and is nowadays dominated by private enclosures as a land management approach.

Valuing ecosystem services for conservation and development purposes: A case study from Kenya

Journal Articles & Books
Diciembre, 2013
Kenya

This paper mapped and valued key inter-related drylands ecosystem services of importance to pastoralists, crop farmers, the tourism industry, conservationists, and policy planners in the Ewaso Ng’iro basin, the largest of the five major basins in Kenya. We used an ecosystem services approach where only final benefits are valued to avoid double counting. The final benefits are ecosystem services or commodities which have an economic value.

Long-term water balance and conceptual model of a semi-arid mountainous catchment

Journal Articles & Books
Diciembre, 2011
Estados Unidos de América

Long-term water balance investigations are needed to better understand hydrologic systems, especially semi-arid mountainous catchments. These systems exhibit considerable interannual variability in precipitation as well as spatial variation in snow accumulation, soils, and vegetation. This study extended a previous 10-year water balance based on measurements and model simulations to 24years for the Upper Sheep Creek (USC) catchment, a 26ha, snow-fed, semi-arid rangeland headwater drainage within the Reynolds Creek Experimental Watershed in southwestern Idaho, USA.

What lies beneath: detecting sub‐canopy changes in savanna woodlands using a three‐dimensional classification method

Journal Articles & Books
Diciembre, 2015

QUESTION: Increasing population pressure, socio‐economic development and associated natural resource use in savannas are resulting in large‐scale land cover changes, which can be mapped using remote sensing. Is a three‐dimensional (3D) woody vegetation structural classification applied to LiDAR (Light Detection and Ranging) data better than a 2D analysis to investigate change in fine‐scale woody vegetation structure over 2 yrs in a protected area (PA) and a communal rangeland (CR)? LOCATION: Bushbuckridge Municipality and Sabi Sand Wildtuin, NE South Africa.
