december, 2009
Central Asia

Based on soil characteristics, watertable level, mineral composition of plant biomass, morphological/reproductive traits and carbon discrimination values, a new concept for the classification of halophytes was developed. Six main groups of halophytes have been described within the desert flora of Central Asia. Significant changes on chemical contents of ions: Cl⁻, SO₄ ²⁻, HCO₃ ⁻, Na⁺, K⁺, Ca²⁺ and Mg²⁺among 23 studied halophytic forage species were revealed.

Land use/cover changes and their implications on rural livelihoods in the degraded environments of central Tanzania

Tanzania

This paper examines the changes in land use/cover types in the degraded environment of central Tanzania over the last 45 years, and how such changes have influenced agricultural and livelihoods sustainability, especially in the Irangi Hills. Changes of land use/cover were measured through aerial photographs interpretations, while local perceptions and description of change were addressed through household interviews and field observations. The results of this study show that there have been variations over the years in terms of both the areas and spatial distribution of cultivated fields.

Critical success factors of a whole of business extension approach for increased capacity of beef producers and improved enterprise profit and sustainability

Journal Articles & Books
december, 2009

The 'Research to Reality Project' assisted beef producers in the Burdekin catchment of north Queensland to develop practical responses to a range of production and grazing land management challenges. The project involved three groups of beef producers encompassing 19 enterprises, 680000ha of land and the management of 162000 cattle. The project was founded on a continuous improvement and innovation approach, and included an employed industry champion and multi-disciplinary project team who used a range of extension methods to identify, develop and implement on-property projects.

Effects of grazing and experimental warming on DOC concentrations in the soil solution on the Qinghai-Tibet plateau

Journal Articles & Books
december, 2009

Little information is available about the effects of global warming and land management on dissolved organic carbon (DOC) concentration in soil solution in the field. Here, for the first time, we used a free-air temperature enhancement (FATE) system in a controlled warming-grazing experiment in 2006 and 2007 to test the hypothesis that grazing modifies the response of soil solution DOC concentration to experimental warming.

Active land use improves reindeer pastures: evidence from a patch choice experiment

Norway

The industrialization of agriculture in western societies has often led to either intensified use or abandonment of farmland and open pastures, but experimental evidence on how the dynamics of farmed ecosystems affect space use by large herbivores is limited. We experimentally manipulated farmland patches with cutting and (early summer) low- and high-intensity domestic sheep Ovis aries grazing according to traditional use in north Norway.

Determinants of access to forest products in southern Burkina Faso

Africa

There is an increasing understanding that forests and the forestry sector are key elements in poverty reduction strategies in Africa. However, issues of equity between various forest users are becoming a major challenge to environmental development, forest management and poverty reduction. This paper presents an analysis of household representatives' socio-economic determinants and other constraints on accessing forest products, based on data collected through a questionnaire survey of 1865 respondents in seven districts of the Sissili province, southern Burkina Faso.

The study was carried out in Metema Woreda of Amhara National Regional State. The objectives of the study were to describe the goat production systems in the study area and to identify major constraints and opportunities of goat productivity; to evaluate the effect of supplementation with different protein sources on live weight gain of grazing goats under farmers management and to evaluate the economic feasibility of the feeding system under farmers condition.

Ethiopia

Transhumance, the seasonal movement of herds occurring between two points and following precise routes repeated each year, is practiced on a broad scale in the open field areas of Tigray (North Ethiopia). This article presents a characterization of the practice, factors that explain its magnitude, and recent changes. Eleven villages were selected randomly, semistructured interviews were conducted, and data on the sites were collected both in the field and from secondary sources.
