Au Burkina Faso, le potentiel en terres arables à vocation agricole est épuisé. À l’avenir, la population en rapide expansion ne pourra être nourrie que s’il est possible d’accroître les rendements sur les terres cultivées existantes. Grâce à la construction de cordons pierreux le long des courbes de niveau, il est possible de mieux exploiter l’eau de pluie et de stopper l’érosion.

Les populations vivant aux alentours d’aires protégées doivent développer de nouveaux moyens de subsistance pour assurer leur survie. Les populations riveraines des forêts dépendent souvent de l’utilisation des produits et services que leur offrent les ressources naturelles. L’exploitation de ces produits jadis «gratuits» est aujourd’hui réglementée et limitée, notamment pour des raisons environnementales.

Une équipe de scientifiques de l’International Livestock Research Institute (ILRI) a identifié toutes les zones à haut risque du monde dans lesquelles la famine et les conséquences négatives du changement climatique s’exacerberont particulièrement violemment. Ces régions sont principalement situées en Afrique et en Asie du Sud, mais la Chine et l’Amérique latine pourraient également être concernées. Dans moins de 40 ans, la saison agricole de ces régions sera plus courte, plus chaude et plus sèche, mettant en danger des centaines de millions de personnes déjà très démunies.

Momentum is building to include agriculture in carbon nancing initiatives, and the stakes are large – for climate change mitigation, for food security and poverty alleviation. For many smallholder farmers, insecure land and resource rights are a barrier to participation in mitigation programmes, but there are ways forward

Mongolia has very significant natural resources and a large part of the population is dependent on them for their daily living. The impact of the state of the environment on the living standards of herders is obvious, but also Mongolians living in the capital Ulaanbaatar have learned that air pollution, especially in winter, and other environmental problems have a deep impact on their living standards. The Government of the Netherlands has established a Trust Fund at the World Bank to support environmental activities in Mongolia.

Contains country context, study of land investment, benefits and impacts. Finds wide discrepancies between public positions and laws and what is happening on the ground, an absence of environmental controls, widespread displacement from farmland without compensation, little local benefit, many land deals involve small-scale investors with limited agricultural experience.

Includes Sierra Leone: open for business, land use and land tenure in Sierra Leone, land deal in Sierra Leone: four case studies, responsible agro-investment? Found a lack of transparency and public disclosure in all aspects of the four land deals, an extremely weak regulatory framework, confusion around ‘availability’ of land, lack of environmental protection, conditions ripe for exploitation and conflict.

Includes Mali – a welcoming climate for investors, the regulatory framework – bending it to suit investors?, the Office du Niger, case studies of four investments, large land deals in Mali. Found more than 40% of land deals involve crops for agrofuels, violent and flagrant abuses of human rights in the agricultural zones of the Office du Niger, a serious lack of public disclosure and transparency from government, an alarming lack of environmental protection.

Scientists predict that global warming will cause suitable habitat ranges to shift for many plant species, including blue oak in California. If proximity to particular land cover types significantly affects human welfare, any such shifts will affect household welfare, resulting in an indirect cost that is currently unaccounted for in the climate change literature. Using a hedonic pricing model, the marginal values of blue oaks and the land cover types most likely to replace them are estimated at multiple spatial scales using single family residences sold in Kern County from 1997 to 2003.

This paper analyzes the optimal policy choice for the conservation of privately owned openspace when future land cover types are uncertain. Policymakers must use land use policies tomake conservation decisions under uncertainty over the social benefits of future vegetation, dueto the uncertain effects of climate change on suitable habitat ranges. If policymakers fail toaccount for future information gains when designing land use policies, expected social welfaremay not be maximized.

O Desenvolvimento Agrário tem sido desde sempre uma prioridade para Moçambique. Em 1998, o Governo em colaboração com os principais parceiros desenhou o Programa de Desenvolvimento da Agricultura (PROAGRI I) com o objectivo de melhorar a coordenação das intervenções públicas na agricultura e orientar os investimentos..

Since the publication of the Report of the Brundtland Commission (Our Common Future) in 1987, and the consequent Earth Summit on sustainable development, global attention on natural resource scarcity and degradation has been increasing, because of climate change and rising food and energy prices. This awareness, in turn, has led to growing interest in land investments by the private and public sectors. Despite this interest, however, land degradation has not been comprehensively addressed at the global level or in developing countries.
