March 6, 2019 In order to obtain relevant information on the ecosystem services generated by silvopastoral practices in livestock landscapes, the Biodiversity and Sustainable Agro-silvopastoral Livestock Landscapes project, known as BioPaSOS, implemented by CATIE (Tropical Agricultural Research and Higher Education Center), supported the development of a research thesis by a master's student at the Autonomous University of Chiapas (UNACH, its Spanish acronym), which studied carbon storage in tree biomass and soil silvo-pastoral practices at La Sepultura Biosphere Reserve in Chiapas, Mexico.
The research was carried out by the student Alejandra Lara, under the advice of DebRajAryal, professor of chairs of the National Council of Science and Technology (CONACYT, its Spanish acronym) attached to the Faculty of Agronomic Sciences of the UNACH; René Pinto, professor-researcher and leader of the Academic Body of Livestock Agroforestry (CAAP, its Spanish acronym); and José Antonio Jiménez, local coordinator of BioPaSOS project in Chiapas.
For the research, we worked with 30 producers who carry out silvo-pastoral practices inside their cattle ranches, located in 16 communities, distributed in the municipalities of Villaflores, Jiquipilas, Arriaga and Tonalá.
Lara was able to demonstrate with precise data how silvo-pastoral practices (living fences, trees dispersed in paddocks and protein fodder banks) contribute to storing carbon in the tree biomass and in the soil. For example, it found that within silvopastoral practices, dispersed trees and live fences (6.8 and 3.0 Mg C ha--1,, respectively) are the practices that perform the greatest carbon storage compared to other silvopastoral practices.
Jiménez explained that the information generated in this research will be very useful for BioPaSOS project to know the contribution of greenhouse gas (GHG) mitigation in a ranch that develops and implements silvo-pastoral practices within the territory of Chiapas.
The development of this thesis strengthened the collaborative work that has been carried out as part of the research agenda of BioPaSOS project with academic and research institutions in Chiapas.
