Hunting, Social Structure and Human–Nature Relationships in Lower Omo, Ethiopia: People and Wildlife at a Crossroads

Dezembro, 2013
Etiópia

Hunting is often either portrayed as the ultimate means to enact a close connection between the human being and nature, or investigated in terms of its contribution to livelihoods. Through in-depth interviews and focus group discussions, we explored the meaning of hunting in the lower Omo valley, Ethiopia, and found that large game hunting was best understood as an activity that served to establish and maintain human–human relationships.

Institutionalization of common land property in Portugal: Tragic trends between “Commons” and “Anticommons”

Journal Articles & Books
Dezembro, 2013
Portugal

The use and exploitation of natural resources is generally structured by institutions, especially by property institutions. The main objective of this paper is to present a diachronic analysis of the institutionalization of common land property in Portugal. The several types of ownership may be largely explained by common land history. We intend to draw an outline of the emergence, evolution and transition of common land from the late nineteenth century to the present day, using the matrix proposed by Heller.

Understanding Variability in Adaptive Capacity on Rangelands

Journal Articles & Books
Dezembro, 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

Estados Unidos

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.

locally designed payment scheme for agricultural landscape services

Traditional nationwide agri-environmental policy measures are not always efficient to ensure the provision of environmental services that would match peoples’ preferences. This study suggests a landscape value trade (LVT) scheme to be locally implemented so as to ensure the supply of agricultural landscape attributes demanded by local citizens. The feasibility of LVT, a ‘user-financed’ payment for environmental services (PES) scheme, is analysed in a local case from the southern part of Finland. We examine the disposition of both landowners (sellers) as well as residents (buyers).

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

Journal Articles & Books
Dezembro, 2013
Quênia

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.

Woody vegetation dynamics in the rangelands of lower Omo region, southwestern Ethiopia

Etiópia

Woody encroachment is one of the several factors aggravating rangeland degradation in arid and semiarid areas. The goal of this study is to improve our understanding about the relationship between woody encroachment and its potential drivers by analyzing the temporal and spatial pattern of land-cover changes in the lower Omo region of southern Ethiopia. We used a combination of multi-temporal images, as well as climatic and demographic data for the analysis.

Regime shift on the roof of the world: Alpine meadows converting to shrublands in the southern Himalayas

China

Worldwide, changing climates and land use practices are escalating woody-plants encroachment into grasslands, reducing biodiversity and altering ecosystem functions. The loss of alpine grasslands is a major conservation concern as they harbor many rare and endemic species. Alpine meadows in Northwest Yunnan, China, represent a global biodiversity hotspot with high species richness, beta diversity, and endemism. Shrubs have expanded greatly in the region and threaten alpine meadow biodiversity.

Conversion of Communal Grazing Lands into Exclosures Restored Soil Properties in the Semi-Arid Lowlands of Northern Ethiopia

Etiópia

In the semi-arid tropics, communal grazing lands provide a livelihood for millions of people. However, it is highly threatened by overgrazing and continuous land degradation and, as a result, proper management is important to improve the livelihood of the people. This study investigated the effectiveness of exclosures established on communal grazing lands to restore soil properties and identified the relationship among soil properties, site and vegetation characteristics, and exclosure age.

Rangeland governance in an open system: Protecting transhumance corridors in the Far North Province of Cameroon

Camarões

The mobile pastoral system in the far north region of Cameroon is an excellent example of the paradox of pastoral land tenure, in that pastoralists need secure access to pasture and water, but also flexibility in resource use, i.e. the ability to move elsewhere because of spatio-temporal variation in resource availability.

What determines soil organic carbon stocks in the grazing lands of north-eastern Australia?

Dezembro, 2013
Austrália

This study aimed to unravel the effects of climate, topography, soil, and grazing management on soil organic carbon (SOC) stocks in the grazing lands of north-eastern Australia. We sampled for SOC stocks at 98 sites from 18 grazing properties across Queensland, Australia. These samples covered four nominal grazing management classes (Continuous, Rotational, Cell, and Exclosure), eight broad soil types, and a strong tropical to subtropical climatic gradient.

Wetland management in New Zealand: Are current approaches and policies sustaining wetland ecosystems in agricultural landscapes?

Nova Zelândia

As a signatory to the Convention on Biological Diversity and to the Ramsar Convention on Wetlands, New Zealand has international responsibilities to protect and restore wetland ecosystems. The New Zealand Biodiversity Strategy also reflects New Zealand's commitment to help stem the loss of biodiversity worldwide, including wetlands. Wetland loss in New Zealand has been more significant than in most parts of the world, and ecosystems in fertile lowlands have been most severely impacted by agricultural development.
