Climate change is expected to alter existing coastal habitats in Grenada, jeopardizing the island's mangroves, such as through the conversion of basin mangroves to fringe habitats as storm surges open barrier beaches, increasing tidal action and flood duration.

Likewise, incremental sea level rise and storm overwash can lead to increased salinity within coastal ponds, backwaters, and estuaries.

Each of these processes, acting alone or in concert, can greatly affect colonization by all mangrove species that occur in the region.

The fifth Global Environment Outlook (GEO-5) analyses the state, trends, outlook and responses to environmental change. It assesses progress towards meeting internationally agreed goals and identifies gaps in their achievement.The outlook examines the drivers of environmental change and the overarching socio-economic forces that exert pressure on the environment.

Using a computable general equilibrium (CGE) model this report identifies the links among economic growth, poverty alleviation, and natural resource degradation in Brazil.

This article provides a review of the past and potential future roles of land tenure reforms and land markets in Sub-Saharan Africa (SSA) as responses to population growth in the process of land use intensification and livelihood transformation.

This paper provides a brief overview of the current knowledge and data on deforestation rates, research on the causes of deforestation and forest degradation and relevant policy options. It highlights issues of particular relevance to new discussions on reduced emissions from deforestation and forest degradation (REDD) in developing countries at different stages of forest transition.

This paper analyses issues that affect the role of agriculture as a source of economic development, rural livelihoods and environmental services. Using experiences of land expansion in Asia, Latin America and the Caribbean, Eastern Europe, and sub-Saharan Africa, it assesses the extent to which recent demand for land differs from earlier processes of area expansion and identifies the current challenges, in terms of land governance, institutional capacity and communities’ awareness of their rights.

Considerable hype and debate are currently surrounding the potential of biochar (charcoal created through the burning of biomass in low oxygen environments) in climate change mitigation and agriculture. This report attempts to summarise the arguments, assumptions and interests in the biochar debate and offer reflections on its prospects. The report begins by outlining what it calls the triple-win of biochar. The production of biochar can be tuned to release bioenergy or biofuels in the form of syngas and bio-oil, thus providing decarbonised biomass fuel.

This paper employs an historical analysis to consider some of the consequences of conflicting resource use and political friction on resource exploitation within and outside Turkana District during this century. Given this historical context, development alternatives tested to ameliorate food insecurity are reviewed.The article proposes that the stage for political conflicts, environmental degradation and food insecurity within the region was set decades ago.

Greening rural development can stimulate rural economies, create jobs and help maintain critical ecosystem services and strengthen climate resilience of the rural poor. This report by the Ministry of Rural Development, India, with support from the United Nations Development Programme, presents strategies for inclusive rural development embodying the principles of environmental sustainability. It defines ‘green’ outcomes for major rural development schemes, reviews the design and evidence from the field to highlight potential green results and recommends steps to improve green results.

This United Nations flagship publication launched at the Rio+20 Conference on Sustainable Development in June 2012 aims to raise awareness on sustainability and green growth. The objective is to show renewed political commitment for sustainable development, while assessing progress to date. Sustainable development, which is seen as the guiding principle for long-term global development, consists of three pillars: economic development, social development and environmental protection.

This paper examines how developing countries have attempted to promote rural development through biofuel production, what social outcomes those strategies have created and what lessons can be learned. This is done by comparing the contexts of Brazil, India and Indonesia; three countries with important agricultural sectors that have put large-scale biofuel programmes in place. The analysis indicates a disparity between the social discourse and the adopted biofuel policy instruments.
