In the ten years since it came into being, the United Nations Convention to Combat Desertification (UNCCD) has had little or no effect on the further encroachment of deserts. More than 80 countries have submitted National Action Programmes to combat desertification, but they appear to lack the financial and political commitment to implement them. What are the causes behind the UNCCD's weakness? How can the Convention be incorporated more effectively and efficiently into the architecture of international development?

This study assessed the contribution of Geita Gold Mine (GGM) to the livelihoods of local communities in Geita District. Specifically, it assessed the effectiveness of corporate social responsibility implementation, determined the extent to which GGM has contributed to socio-economic development in the study area, and examined the communities’ perceptions of environmental problems associated with mining activities and their impact on community well-being. A cross-sectional research design was employed, in which qualitative and quantitative methods of data collection were used.

A fact-finding mission team was formed as a result of consultative meetings on the land dispute between the village government and pastoralists in Vilima Vitatu village in Babati district. The team was comprised of the following members: Kassian Mshomba (LHRC), Seif Mangwangi (Majira), Diana Mawalla (PINGOs Forum), Hamadi Sadick, Emmanuel Cornel (PINGOs Forum), Asraji Mvungi (ITV), Rodgers Luhwago (The Citizen), Bakari Mnkondo (Uhuru), Bernard Baha (HakiArdhi) and Chambi Chachage (Independent Researcher).

The world is increasingly encroaching on indigenous peoples’ traditional lands. Around the globe, indigenous communities are forced to cede ground to state development, corporate land grabs, rising sea levels, environmental degradation, and population growth. The right to land provides the basis for access to food, housing, and development. But for indigenous peoples, traditional lands are more than this; they represent essential ties to their ancestors, their culture, and their languages. Losing their land means losing their way of life.

Restoration of mangroves is often considered a way to minimize losses incurred from their decline and to provide additional services to coastal communities. However, the success of restoration programs is often focused on biological or ecological criteria. The situation is no exception in Bangladesh, which houses the world's largest mangrove plantations. This study has been undertaken in a south-central estuarine island (Nijhum Dwip) of the Bangladesh coast and aims to understand societal perception on the achievements of a plantation program.

Stands of quaking aspen (Populus tremuloides) rank among the most biologically diverse plant communities across the intermountain region of western North America. Marked declines of aspen have occurred in recent decades, likely due to a combination of effects from changes in fire regimes, herbivory, climate (e.g. drought), and interspecific competition with conifer species. However, it is poorly understood how the effects of these factors are manifested at a landscape scale over decadal time periods.

Mediterranean agro-forestry systems are undergoing rapid change due to abandonment. This turns formerly cultivated or grazed oak-tree parklands (i.e., savanna-type formations called “dehesas”) into flammable formations of scattered trees within a matrix of shrubs with open spaces. Wildfires can now occur, threatening the persistence of these formations. Fire-prone shrublands commonly regenerate after fire from seeds stored in the soil.

Both fire and conifer encroachment can markedly alter big sagebrush communities and thus habitat quality and quantity for wildlife. We investigated how conifer encroachment and spring prescribed burning affected forage and cover resources for a sagebrush specialist, the pygmy rabbit. We studied these dynamics at spring prescribed burns in southwestern Montana and eastern Idaho during the summer of 2011.

To assess the spatial patterns of forest expansion (encroachment and densification) for mountain pine (Pinus uncinata Ram.) during the last 50 years at a whole mountain range scale by the study of different topographic and socio-economic potential drivers in the current context of global change. The study area includes the whole distributional area of mountain pine in the Catalan Pyrenees (north-east Spain). This represents more than 80 municipalities, covering a total area of 6018 km².

The encroachment of woody species in natural grasslands has recently increased, especially in arid and semi-arid environments. In the Mediterranean region, this is mainly attributed to the dramatic decrease of the traditional human activities such as pastoral management and fuelwood collection, which controlled the encroachment of woody species. The purpose of this study was to investigate the effects of Juniperus oxycedrus encroachment on herbage production and floristic diversity in a natural grassland.

Piñon (Pinus spp.) and juniper (Juniperus spp.) expansion and infilling in sagebrush (Artemisia L.) steppe communities can lead to high-severity fire and annual weed dominance. To determine vegetation response to fuel reduction by tree mastication (shredding) or seeding and then shredding, we measured cover for shrub and herbaceous functional groups on shredded and adjacent untreated areas on 44 sites in Utah.

Ranching generally causes a progressive deforestation. Nevertheless in Mediterranean countries trees are still present in many pastoral systems, here referred to as silvopastoral systems (SPs). Trees provide products as fruits as human food, fruits or leaves as fodder, wood and firewood, environmental services like patches of soil fertility and shelter for animals, and environmental goods such as carbon sequestration, water yield and quality and reinforced biodiversity.
