Feasibility and competitiveness of intensive smallholder dairy farming in Brazil in comparison with soya and sugarcane: Case study of the Balde Cheio Programme

Journal Articles & Books
Décembre, 2013
Brésil

Technology introduction and the intensive use of resources, particularly in smallholder farming systems, are at the core of debates about future food security and sustainable livelihoods. In Brazil, land use changes promoted by competing agricultural chains require a search for alternative modes of production for family farms. We analyse the technical and economic viability of intensification of dairy farming by smallholders in the “Balde Cheio” (Full Bucket) programme.

États-Unis d'Amérique

Land-cover change in the conterminous United States was quantified by interpreting change from satellite imagery for a sample stratified by 84 ecoregions. Gross and net changes between 11 land-cover classes were estimated for 5 dates of Landsat imagery (1973, 1980, 1986, 1992, and 2000). An estimated 673,000km²(8.6%) of the United States’ land area experienced a change in land cover at least one time during the study period. Forest cover experienced the largest net decline of any class with 97,000km² lost between 1973 and 2000.

Divergent interests and ideas around property rights: The case of berry harvesting in Sweden

Journal Articles & Books
Décembre, 2013
Suède

This paper illustrates the clash between interests and ideas concerning property rights and regulation by analyzing the ongoing debate on the right of public access in Sweden, which has recently intensified due to an influx of foreign professional berry harvesters. The conflicts in Sweden are found to stem from contradictory concepts concerning property (notably, ownership and the right of public access) and ideological differences in terms of whether forest resources should be regulated by government or governance.

How do policy options modify landscape amenities? An assessment approach based on public expressed preferences

Journal Articles & Books
Décembre, 2013
Portugal
France

Facing the changes in the agricultural sector as well as new growing demands from society in relation to the European countryside, new questions emerge as to the management of the agricultural landscapes. The multiple combination of production with the support of multiple functions is a challenge for present day management. Tools are needed that make it possible to assess how a certain landscape can support in particular cultural and amenity functions, those that directly depend on the public preferences.

Valuing ecosystem services for conservation and development purposes: A case study from Kenya

Journal Articles & Books
Décembre, 2013
Kenya

This paper mapped and valued key inter-related drylands ecosystem services of importance to pastoralists, crop farmers, the tourism industry, conservationists, and policy planners in the Ewaso Ng’iro basin, the largest of the five major basins in Kenya. We used an ecosystem services approach where only final benefits are valued to avoid double counting. The final benefits are ecosystem services or commodities which have an economic value.
