The world is three-quarters water and the Latin American and Caribbean region is considered to have comparatively greater availability of this resource: an estimated 30% of the world's fresh water. But human activities are besieging this wealth of water, threatening both its quality and quantity.
Ecuador is not unfamiliar with this reality. The internal water resources available...
<p>The Sierra Nevada figures boldly in the earliest American articulations of environmental conservation and protection and civil organizing around this concern. The founder of Sierra Club, naturalist John Muir, focused attention on these mountains and since then they have been kept on or near center stage by environmentalists. It is from the early 1990s however, that Californians more...
The high mountains of the world represent one of the most extreme environments on our planet. Yet they are of immense value to mankind as sources of food, fibre, minerals and water; and they are rich in a variety of living natural resources. Though mountainous regions stand above their surroundings, usually more densely populated plains, they are linked to them in numerous ways...
Since 1990 interest in mountains has received an impetus with the establishment of the IUCN Commission on Mountain Protected Areas and the inclusion of Article 13 (Fragile Mountain Environments) of Agenda 21 at the United Nations Conference on Environment and Development (UNCED). Today there is growing awareness at policy, research and activist levels that the well-being of lowland areas is...
The paper describes the goals and objectives for a programme of work on mountain biological diversity.
The planet Earth is able to sustain life because of the existence of water in liquid form on its surface. More precisely, the lifeforms on Earth have flourished because of the simultaneous availability of air, water and soil over large parts of the surface of this planet, which made the-production of biomass possible. Among these three planetary resources, the availability of water, in...
Dr. Miller discussed a draft of his forthcoming World Resources Institute Report "Balancing the Scales - Policies for Increasing Biodiversity's Chances through Bioregional Management." He presented four different approaches to biodiversity conservation, and analyzed their strengths and weaknesses in order to synthesize policy recommendations for managing conservation through...
