This paper focuses on the following areas: reducing methane emissions from ruminant animals (cattle, sheep) by modification of plant composition; reducing nitrous oxide emissions by making the use of nitrogen more efficient both in terms of going from soil to plant and in the animal; plant breeding may also enhance carbon sequestration in grasslands by focusing both on below ground traits of importance and on the composition of material returned to the soil as litter; and the processes involved in fertiliser production, particularly nitrogen fertilisers, result in considerable greenhouse gas
For drylands with low inherent levels of biological productivity, coping with climate change presents particular problems. The world’s drylands cover over 40 % of the global terrestrial area and house more than 2 billion inhabitants MEA, (2005). The world’s poorest people live in these areas and they will be hit hardest by the adverse effects of climate change. The effects will manifest themselves not through increased temperatures per se but rather via changes in hydrological cycles characterised by both increased droughts and paradoxically, increased risks of flooding.
Markets for ecosystem services are being promoted across the developing world, amidst claims that the provision of economic incentives is vital to bring about resource conservation. This article argues that equity and legitimacy are also critical dimensions in the design and implementation of such markets, if social development goals beyond economic gains are to be achieved. The article examines this issue by focusing on two communities involved in a project for carbon sequestration services of forests in the state of Chiapas, Mexico.
Too many people striving for too high a standard of living and purusing the so called "rates of growth" and "aping the unsustainable life styles" of the West are destroying the natural regulatory powers of the Earth.
In the early 1970s, facing overwhelming obstacles, a young visionary named Paolo Lugari set out to build a sustainable village on los llanos, the remote plains of Colombia, some 500 kilometers east of the country
Study focusing on organic agriculture and mitigation and adaptation to predictable and unpredictable impacts of climate change - looks at the general contribution of agriculture to climate change; discusses the considerable potential of organic agriculture for reducing emissions of greenhouse gases, and its contribution to sequestration of CO2 in the soil; outlines weaknesses of organic agricultur
