Our Project “Research Network for the Evaluation of Carbon Sequestration Capacity of Pasture, Agro-pastoral and Silvo-pastoral Systems in the American Tropical Forest Ecosystem” is framed under Climate Change research: mitigation alternatives for vulnerable ecosystems in developing countries. It’s main goal is to contribute to sustainable development, poverty alleviation and mitigation of the undesirable effects of greenhouse gasses on climate change, in particular CO2. It combines efforts from the national research community, represented by CIPAV and Universidad de la Amazonia, and the international research community, represented by CIAT, CATIE and Wageningen University and Research Centre.

Evaluate and compare the level of carbon accumulation and the socio-economic benefit to the farmer, of a range of pasture, agro-pastoral and silvo-pastoral systems in small and a medium-size farms in sube-cosystems vulnerable to Climate Change. Sub-ecosystems considered are: Eroded Andean Hillsides in Colombia; Semi-humid and Humid Tropical Forest in Costa Rica; Humid Tropical Forest in Colombian Amazonia; and possibly Well-drained and Poorly drained Tropical Savannah in Colombia.
The different land management systems are compared against two references states: degraded pasture (negative control) and natural forest (positive control).
Research aims at identifying and recommending improved and sustainable pasture, agro-pastoral and silvo-pastoral systems that represent a viable and economically attractive solution to the farmer (alleviating poverty) and offer environmental services, particularly increases in soil organic matter, carbon accumulation and carbon sinks.

We express our gratitude to the Netherlands Ministry of Development Cooperation in the Hague, The Netherlands Embassy in Bogotá, Colombia, and the Netherlands Embassy in San José, Costa Rica for making real this important project.
We are happy to share our experience with other research/development institutions and colleagues from the developed and developing world. Any effort to enhance our network on carbon sequestration research for tropical ecosystems is welcome.
With our best wishes for success,
María Cristina Amézquita
Project Scientific Director
