This paper focuses on the causes of ecosystem degradation. Historically, poor communities have been identified as among the key degrading agents. The thesis of this paper is that such communities do not voluntarily destroy the resource base which is the source of their livelihoods and provides them sustenance. Therefore, the damage that they visibly cause is induced by institutional failure.

The potential of grazing lands to sequester carbon must be understood to develop effective soil conservation measures and sustain livestock production.

Methane (CH4) uptake by steppe soils is affected by a range of specific factors and is a complex process. Increased stocking rate promotes steppe degradation, with unclear consequences for gas exchanges. To assess the effects of grazing management on CH4 uptake in desert steppes, we investigated soil-atmosphere CH4 exchange during the winter-spring transition period.

Soil organic carbon (SOC) is the largest among three major carbon pools of global ecosystems. During the past few years, global warming and forcible land-use changes have resulted in a huge loss of this major carbon pool and as a consequence, concentration of atmospheric CO2 has increased. To mitigate the potential risks arising from atmospheric abundance of CO2, adoption of carbon sequestration strategies at different landscape scales is a major option. For this

We assessed a donor-funded grassland management project designed to create both conservation and livelihood benefits in the rangelands of Mongolia's Gobi desert. The project ran from 1995 to 2006, and we used remote sensing Normalized Differential Vegetation Index data from 1982 to 2009 to compare project grazing sites to matched control sites before and after the project's implementation.

Dust is all that's needed to plunge the world into an ice age. When blown into the sea, the iron it contains can fertilise plankton growth on a scale large enough to cause global temperatures to drop. The finding adds support to the idea of staving off climate change by simulating the effects of dust - perhaps by sprinkling the oceans with iron filings.

To convert deserts into arable, green landscapes is a global vision, and desert farming is a strong growing area of agriculture world-wide. However, its effect on diversity of soil microbial communities, which are responsible for important ecosystem services like plant health, is still not known.
