Soil microbial biomass in semi-arid-communal sandy rangelands in the Western Bophirima district, South Africa
Soil microbial biomass is considered as an important early indicator of changes that may occur
in the long term with regard to soil fertility and constitutes an important source and sink of nutrients. In
South Africa, rangeland monitoring has mostly focused on assessing changes of aboveground vegetation
in response to land uses effects, but the associated changes at belowground soil level remain a topic of
further research. The aim of this study was to explore soil microbial biomass at three sites under
State of Climate Change Adaptation and Mitigation Efforts for Agriculture in Bhutan
Bhutan is least developed, mountainous and landlocked country in the eastern Himalayan range with a population of over 600,000. However its population and ecosystems are vulnerable to climate change. Despite a high level of environmental protection and awareness, Bhutan has become a victim of the global impacts of climate change caused by emissions in other countries. There is little historical climate data available in Bhutan; current records date back only to 1994. Consequently, the future climate scenario for Bhutan is uncertain.
Spatial and temporal contrasts in the distribution of crops and pastures across Amazonia: a new agricultural land-use dataset from census data since 1950
Soil organic carbon dynamics, functions and management in West African agro-ecosystems
Spatial correlates of land-use changes in the Maasai-Steppe of Tanzania: Implications for conservation and environmental planning
Spatially explicit models are becoming increasingly important tools for simulating land-use change. In this study, we formulated and tested models that incorporated spatial correlates of agricultural expansion and used them to predict local- and landscape-scale patterns of agricultural land-use change and its implications in the Maasai-Steppe of Northern Tanzania. We evaluated the relationship between agricultural land-use and its spatial correlates using Multiple Logistic Regression on data derived from satellite imageries for the year 2000.
Soil organic carbon stocks in semi-arid West African drylands: implications for climate change adaptation and mitigation
In the West African drylands, SOC sequestration is seen as one of the prominent strategies to both enhance the resilience of agro-ecosystems and mitigate global greenhouse effects. However, there is a dearth of baseline data that impede the design of site-appropriate recommended management practices (RMPs) to improve and sustain SOC accrual.
Status, distribution and determinants of poverty in the COMESA region: A review of existing knowledge
Poverty and vulnerability are among the major problems in Eastern and Southern Africa (ESA). To design appropriate poverty reduction initiatives for the region, it is not only important to understand the distribution of poverty but also the determinants. Various reports have documented information on the status, distribution and determinants of poverty in each of the countries.
Spatial planning: Making space for livestock and wildlife
Soil restoration after seven years of exclosure management in northwestern Ethiopia
Ecological restoration through exclosure establishment has become an increasingly important approach to reversing degraded ecosystems in rangelands worldwide. The present study was conducted in northwestern Ethiopia where policy programs are aiming to restore degraded lands. Changes in soil properties following establishing exclosures on communal grazing lands were investigated. A space-for-time substitution approach was used to monitor changes in soil properties after conversion of communal grazing lands to exclosures with ages of establishment ranging from 1 to 7-years.
