Parientes silvestres, transgénicos y la conservación de los recursos genéticos

Journal Articles & Books
Décembre, 2016
Colombie

El propósito de este documento es fortalecer la capacidad de agentes públicos y privados para la aplicación de la PNGIBSE, que constituye en sí misma una apuesta de interfaz entre ciencia, política y sociedad en la perspectiva de construir sostenibilidad en el desarrollo. Además de ello, representa un insumo para el seguimiento a los compromisos del país frente a convenios e iniciativas internacionales (CDB, IPBES, OCDE), así como un mecanismo pedagógico para generar interés, conciencia y apropiación de las diferentes dimensiones de la biodiversidad del país.

Participating in REDD+ Measurement, Reporting, and Verification (PMRV): Opportunities for Local People?

Journal Articles & Books
Décembre, 2014

Assessing forest changes is the baseline requirement for successful forest management. Measurement, Reporting, and Verification (MRV) are three essential components for achieving such assessments. Community participation in resource monitoring and management is increasingly seen as a scientifically efficient, cost-effective, and equitable way to employ such practices, particularly in the context of REDD+. We developed a multidisciplinary approach to study the feasibility of Participatory MRV (PMRV) across three sites along a forest degradation gradient in Indonesia.

Mud, muddle and models in the knowledge value chain to action on tropical peatland issues

Journal Articles & Books
Décembre, 2014

Tropical peatlands are known not only for their high, area-based, carbon emissions in response to land-use change but also as hot spots of debate about associated data uncertainties. Perspectives are still evolving on factors underlying the variability and uncertainty. Debate includes the ways of reducing emissions through rewetting, reforestation and agroforestry.

Methods to investigate the hydrology of the Himalayan springs: a review

Reports & Research
Décembre, 2016

Springs are the major source of freshwater in many small mountainous watersheds within the Himalayan region. In recent years, their flow rates have diminished, but the reasons for this are not self-evident, and hence this paper reviews the methods to investigate Himalayan springs. The review reveals that chemical and isotope analyses – mostly water dating and stable isotope (e.g., d18O) analyses – could be an appropriate entry point to commence field investigations, because of their potential to map complex spring pathways, including linkages between aquifers.

Mapping gender preferences for tree and shrub forages

Journal Articles & Books
Décembre, 2014

The book is structured to cover a range of gender issues in various forest, trees and agroforest management areas from tree species identification to landuse decision-making. Participatory research tools are featured such as ranking, mapping, modeling, participatory GIS; and other tools that can aid in looking at gender issues, roles and preferences primarily but not limited to agroforestry research and development.

Managing Semi-Arid Rangelands for Carbon Storage: Grazing and Woody Encroachment Effects on Soil Carbon and Nitrogen

Journal Articles & Books
Octobre, 2015
Afrique
Afrique orientale

High grazing intensity and wide-spread woody encroachment may strongly alter soil carbon (C) and nitrogen (N) pools. However, the direction and quantity of these changes have rarely been quantified in East African savanna ecosystem. As shifts in soil C and N pools might further potentially influence climate change mitigation, we quantified and compared soil organic carbon (SOC) and total soil nitrogen (TSN) content in enclosures and communal grazing lands across varying woody cover i.e. woody encroachment levels.

Mapping adaptive capacity and smallholder agriculture: applying expert knowledge at the landscape scale

Journal Articles & Books
Septembre, 2016
Costa Rica
Guatemala
Honduras
Amérique centrale
Amérique du Sud

The impacts of climate change exacerbate the myriad challenges faced by smallholder farmers in the Tropics. In many of these same regions, there is a lack of current, consistent, and spatially-explicit data, which severely limits the ability to locate smallholder communities, map their adaptive capacity, and target adaptation measures to these communities.

Land Rights and Women's Empowerment in Rural Peru: Insights from Item Response Theory

Journal Articles & Books
Juin, 2016
Amérique centrale
Amérique du Sud

Women’s land rights are increasingly advocated as an empowerment tool to spur development outcomes. However, empirical evidence of this relationship is limited. In this study we use data from peasant communities in rural Peru to explore the effect of the intra-household allocation of inherited land on women’s empowerment. Empowerment is modeled as a latent variable measured by different influence indicators using a Generalized Structural Equation approach.
