The purpose of the research summarized in this paper is to provide policy-relevant knowledge on the governance of rural services in Guatemala and thus to contribute to improving the provision of services that are essential for agricultural and rural development. Based on quantitative and qualitative primary data, we examine how services are actually provided today and how community preferences and participation affect service provision in rural Guatemala. Our main finding is that the provision of formally decentralized services by local governments is incomplete.

Shallow landslides induced by heavy rainfall events represent one of the most disastrous hazards in mountainous regions because of their high frequency and rapid mobility. Recent advancements in the availability and accessibility of remote sensing data, including topography, land cover and precipitation products, allow landslide hazard assessment to be considered at larger spatial scales. A theoretical framework for a landslide forecasting system was prototyped in this study using several remotely sensed and surface parameters.

This paper analyzes the intersection of two parallel developments that have had a curious impact on agrarian politics in Colombia: on the one hand, attempts to appropriate land for ‘green’ ends such as biofuel production, which have become ubiquitous all across Latin America, and on the other, the implementation of multicultural reforms, which in Colombia resulted in the collective titling of more than five million hectares of land for ‘black communities’.

The rising discussion on carbon balance of tropical forests often does not consider the sequestration potential of secondary dry forests, which are becoming an increasing importance due to land use change and reforestation. We have developed an easy applicable tool for the estimation of biomass increment of tropical secondary forest stands on the base of tree ring analysis. The existence of annual rings was shown by a combination of anatomical examination and radiocarbon estimations.

Addressing global fisheries overexploitation requires better understanding of how small-scale fishing communities in developing countries limit access to fishing grounds. We analyze the performance of a system based on individual licenses and a common property-rights regime in their ability to generate incentives for self-governance and conservation of fishery resources. Using a qualitative before-after-control-impact approach, we compare two neighbouring fishing communities in the Gulf of California, Mexico.

Considering the potential of shaded coffee plantations mixed with natural vegetation for promoting biodiversity conservation, this project assessed the utility of multi-date Landsat Thematic Mapper (TM) satellite imagery for the characterization of natural vegetation versus coffee plantations in western El Salvador. For assembling a multi-temporal Landsat TM data set, we applied a regression analysis model to remove cloud cover and cloud shadows. Then, through a hybrid classification approach, a nine-class land use/land cover (LULC) map was generated.

Payment for ecosystem services (PES) has been widely promoted as an effective and efficient model for conservation; however, few studies have empirically examined how the market-based approach interacts with farmer's decision-making processes and their abilities to sustain new conservation practices. This paper examines the sustainability of a PES silvopastoral programme in Colombia from peasant farmersâ perspectives.

Liu, X., Burras, C. L., Kravchenko, Y. S., Duran, A., Huffman, T., Morras, H., Studdert, G., Zhang, X., Cruse, R. M. and Yuan, X. 2012. Overview of Mollisols in the world: Distribution, land use and management. Can. J. Soil Sci. 92: 383â402. Mollisols â a.k.a., Black Soils or Prairie Soils â make up about 916 million ha, which is 7% of the world's ice-free land surface. Their distribution strongly correlates with native prairie ecosystems, but is not limited to them. They are most prevalent in the mid-latitudes of North America, Eurasia, and South America.
