This study aimed to evaluate the impact of climate change on the geographical distribution of selected native species from two areas from West Asia and North Africa. Three species representing two genera were selected for assessment of their vulnerability to climate change. The first species was Salsola vermiculata L. which is common to both study areas. The second genus was represented by two species, Haloxylon salicornicum (Moq.) Bunge from the Syrian rangelands and H. schmittianum Pomel from southern Tunisia.

La investigación buscó explicar cómo, a través de los siglos, la noción y las características de la propiedad, que actualmente leyes y manuales nos delimitan con meridiana claridad, no fue estática ni congelada en el tiempo.

Rural and livelihood studies, alongside development organisations, are stressing the importance of gender awareness in debates over food security, food crises and land tenure. Yet, within the Socialist Republic of Vietnam, these gender dynamics are frequently disregarded. In Vietnam, rice is intimately linked to the country’s food security. Over the last decade, rice export levels, production methods, and local and global market prices have remained constant preoccupations for governmental and development agencies.

Since the early 1960s, notwithstanding dire predictions of agricultural theorists and colonial observers, agricultural growth has been strong among most Southeast Asian countries. More recently, this expansion has reached the maritime domain, with the rapid development of aquatic production through sea-based aquaculture among others. In recent territorial expansion and increase in yields for export crops has been faster than for food crops.

Production of commodities for global markets is an increasingly important factor of tropical deforestation, taking over smallholders subsistence farming. Measures to reduce deforestation and convert shifting cultivation systems towards permanent crops have recently been strengthened in several countries. But these changes have variable environmental and social impacts, including on ethnic minorities. In Vietnam, although a forest transition - i.e.

In the context of Knowledge for Climate programme, an expert pool was requested from Theme 6 (high quality climate projections) to provide data and information to study the future impacts of climate change on the agricultural land-use patterns in the Netherlands. More specifically, a number of questions were posed in regard to: 1) representing and explaining the spatial distribution of different types of farming; and 2) simulating with Land Use Scanner the future developments of agricultural land-use while taking into account effects of climate change and changes in (agricultural) policy.

Other papers concerning agricultural economics frequently emphasise a problem of low resource productivity. However, the measuring methods are controversial, because they do not consider a progressive depreciation of fixed assets in agriculture and the new utilities of land on the conditions of sustainable development. These preconditions entitle to formulate a hypothesis that a productivity of capital in agriculture in Poland is increasing because of intrinsic values of agricultural areas. This implies a need of rethinking the neoclassical land rent theories.
