Soil erosion is considered to be one of the greatest environmental problems of sub-Saharan Africa. This paper investigates the advantages and disadvantages of modelling soil erosion at the continental scale and suggests an operational methodology for mapping and quantifying 10-daily water runoff and soil erosion over this scale using remote sensing data in a geographical information system framework.

CONTEXT: Century-long interaction between societies and their environment has shaped the cultural landscapes across Europe. Specific farming systems have persisted for long periods, and their abandonment has led to far-reaching and rapid changes in patterns of land use and land cover. OBJECTIVE: Taking the example of the municipality of Limpach, located in the Swiss lowlands, we studied the dynamics of cultural landscape and related driving forces in a long-term perspective.

The new scenario framework facilitates the coupling of multiple socioeconomic reference pathways with climate model products using the representative concentration pathways. This will allow for improved assessment of climate impacts, adaptation and mitigation. Assumptions about climate policy play a major role in linking socioeconomic futures with forcing and climate outcomes. The paper presents the concept of shared climate policy assumptions as an important element of the new scenario framework.

Livestock-wildlife interactions promote the transmission of a wide range of infectious diseases that constraint livestock production. We used a participatory appraisal approach to find out and rank infectious diseases of concern to pastoralists in a zone of intense wildlife-livestock interaction and another zone with limited interactions. Four villages were selected purposively in areas with intensive cattle-wildlife interactions (zone 1), and another two in areas with low to moderate cattle-wildlife interactions (zone 2).

In several tropical regions of the world, formerly widespread forests have been reduced to scattered remnants, and many tree species are becoming increasingly endangered. Knowledge on the population status of rare species is essential to inform conservation efforts and, in particular, the use of native species for reforestation projects stemming from emerging land-use strategies. We studied 20 mostly red-listed native species in remnant forests on five limestone-, four volcanic- and one ultramafic site(s) across the Visayas in the Philippines, with 40 plots being assessed at each site.

High population density and unscientific land use practices have induced severe land degradation in the fragile Lower Himalayan ecosystem of India. Land cover management has been an effective strategy in managing land degradation through the reduction of water, soil and nutrient losses and improvement in soil fertility and quality.

Meyer’s Parrot Poicephalus meyeri has the widest distributional range of any African parrot. There are six subspecies distributed throughout the African subtropics, all of which manage to breed successfully during the winter dry season when few other cavity-nesting birds are actively nesting. In 2004, we recorded Meyer’s Parrots feeding on four cryptic arthropod larvae incubating inside fruits and pods in their seasonal diet. All of these were previously unknown in the diet of African parrots.

Groundwater vulnerability assessment is an important task in water resources and land management. The most sophisticated among the vulnerability assessment techniques is the GIS-based DRASTIC model. However, despite its popularity, it is marred with excessive subjectivity glitches; little research has been conducted to address the shortcomings associated with this method. This study investigates various issues regarding the application of the GIS-based DRASTIC model through a critical review of relevant literatures.

A conceptual framework is developed and used for improving the livelihood of Sub-Saharan communities faced with multiple stresses resulting from adverse environments, vector-transmitted diseases, and limited food. Ecosocial systems are the units for management. The accumulation of ecological, economic, and social capital is the objective of management, the reduction of maintenance costs is the key strategy, and technologies must satisfy ecological, economic, and social criteria.

An analysis of adaptive landscape amelioration of lands with a geomorphologic classification of characteristic types of agrolandscapes is given. Control of drought and soil-destroying processes is based on a systems approach, including organizational-economic and agro-, phyto-, forest, and hydraulic amelioration measures. The system of ameliorative procedures takes into account the ecological ameliorative requirements and limitations with the developed criteria and standardized evaluation parameters of soils and waters when realizing the concept of adaptive landscape management.
