Richard Waite, associate, Food, Forests and Water Program, World Resources Institute explains: "By intensifying agriculture on existing land and protecting the remaining forests, we can eliminate emissions from land-use change.
Next, it might help the environment: those smallholders manage a disproportionate share of the world's water and vegetation cover, so raising their productivity on existing land would be environmentally friendlier than cutting down the rainforest.
The explanation seems to be that, by killing large numbers of people, AIDS is reducing population pressure on existing land and capital, thus raising labour productivity.However, Clive Bell and Hans Gersbach, both of the University of Heidelberg, and Shanta Devarajan of the World Bank challenge this view.
Therefore, increasing the yield per unit area on existing land is the only way to increase rice production.
Although it is estimated that the costs of such sea reclamation are substantial, in part due to geotechnical concerns for heavy, urban construction, it is still much less expensive than underground construction on existing land.
We define three restoration pathways based largely on existing land use and the degree of modification: restoration for areas of natural ecosystems; repair for production landscapes; and reinvention for urban areas.
Farming system rotations are quantified as a set of continuous spatial probability layers for each phase using a moving window kernel density technique based on existing land use data and these probability layers are used in a weighted allocation of expected profit across the landscape.
The mechanism is based on existing land-tenure management in Mudraw (Papun) District in Karen State, and has brought to light the crucial role that local communities, environmental NGOs, and the de facto ethnic government play in natural resource governance.
These trends may translate to an expansion, rather than a contraction, of the WA-MCF landscape in sub-Saharan Africa, as the present realities of climate change, industrialization and increased pressure on existing land resources portend an inevitable increase in human-wildlife-livestock conflict for the limited pastures, providing ideal conditions for WA-MCF transmission.
