This study provides a framework for the joint analysis of long-term land cover changes and climatic variations at regional scale. The land cover distribution observed in Italy in 1960, 1990, and 2006 was compared with trends in annual precipitation and the aridity index estimated during 1951–2007. Annual rainfall decreased by 0.41% per year during the examined period with the consequent increase in the aridity index (0.48% per year). Both rainfall decrease and aridity increase followed a non-uniform spatial distribution impacting differently the Mediterranean landscape mosaic.
Valuing the ‘bundle of land rights’: On formalising indigenous people's (adivasis) land rights in Kerala, India
Indigenous people's struggles in South India for the last four decades have been centred on the general politics of land rights. However, struggles in the recent past have been clearly delineated as striving to not merely gain access to land for cultivation, but also to claim formal individual titles to parcels of land.
Soil erosion under the impacts of future climate change: Assessing the statistical significance of future changes and the potential on-site and off-site problems
Soil erosion by water is a major environmental threat to the sustainability and productive capacity of agriculture in many tropical and sub-tropical regions of the world. In temperate regions, meanwhile, the ‘off-site’ transport of sediment and pollutants into nearby water courses and the ‘muddy flooding’ of properties and infrastructure pose a much greater threat.
Impacts of innovative forestry land use on rural livelihood in a bimodal agricultural system in irrigated drylands
The conversion of marginal croplands to tree plantations, as an option to address climate change, land degradation, and irrigation water scarcity, as well as to improve the welfare of local population requires prior analysis.
Making sense of policy implementation: The construction and uses of expertise and evidence in managing freshwater environments
This paper explores how environmental policy is implemented and enacted through the management of technical and institutional knowledge at the local level. We use the conservation of the freshwater pearl mussel in the River Esk, North Yorkshire, UK, as an empirical case study to examine the interaction that takes place between professionals from different institutional and disciplinary backgrounds as they come together to work on a common problem. We focus on two aspects: the way in which an institutional context was created; and the interaction between the professionals involved.
