Since 1986, the Centre for Research on Sustainable Farming Systems (CIPAV) has worked in the south-west of Colombia, conducting participatory research studies with peasant farmers and entrepreneurial producers on different aspects of integrated systems. Presently, much of the progress made in generating, validating and applying new know-how regarding these systems...

The Full Value of Parks is the first comprehensive look at the values associated with parks and other kinds of protected areas. Much has been written about the importance of parks to the tourism industry, yet the reasons why people care deeply about them usually have little or nothing to do with money. Instead, people value parks as sacred sanctuaries and places of spiritual self-discovery, as...

Farming systems can be roughly divided into on the one hand large scale, highly mechanized and energy intensive systems managed as corporate agri-businesses and on the other hand small-scale farms, which employ family labour and use limited external inputs. In the small systems, a closer integration of the different components, recycling and optimized use of local resources can enhance...

As the effects of climate change join and exacerbate the conflicts, natural disasters and development projects that drive displacement, Christian Aid fear that an emerging migration crisis will spiral out of control. Unless urgent action is taken, it threatens to dwarf even that faced by the war ravaged world all those decades ago. Christian Aid predicts that, on current trends, a further 1...

Se presentan registros adicionales de Atelopus nahumae y Atelopus laetissimus en la Sierra Nevada de Santa Marta (Magdalena), Colombia, y una caracterización actual de su ecosistema. Las especies son endémicas del macizo montañoso y están clasificadas en Peligro Crítico de extinción por su vulnerabilidad ecológica y por la ausencia de registros...

A dense Andean forest at 3400-3750m elevation, dominated by Weinmannia mariquitae and Miconia spp. in the Colombia Parque Nacional Natural Los Nevados was studied with aerial photographs and vegetation releves. Five main land use types were distinguished: intact upper-Andean forest, upper-Andean forest with selective cutting, the "socola" system, pasture with scattered trees, and total clearings...
A simulation model is proposed, describing vegetation dynamics in a bunchgrass paramo ecosystem, in relation to cattle grazing and burning. Field-work was conducted in Parque Nacional Natural Los Nevados, Colombia, at elevations of 3900-4200m. Three successive stages of vegetation development are recognised in relation to grazing: an opening phase of the bunchgrass layer, conditionally followed...
This is an account of a flying expedition in the Colombian mountains of the Sierra Nevada De Santa Marta.
The Sierra Nevada de Santa Marta is the highest coastal mountain range in the world and covers an area of 17,000 square kilometres. Its population includes some 32,000 members of the Kogi, Arhuaco, Wiwa and Kankuarno indigenous groups, descendants of the Tayronas and preservers of their ancient traditions. There are also approximately 150,000 peasants, and 1.5 million urban dwellers in the...

Process to measure and interpret physical and chemical characteristics that regulate soil behaviour in relation to water, nutrient storage and infiltration: Case of the Fuquene Lake.

The Fúquene river basin is located in the central part of Colombia near the city of Bogotá and has an area of 187,000 hectares. This watershed was selected because the lake is suffering...
