Incentive-based programs to reduce deforestation are expected to play an increasinglyimportant role in global efforts to protect ecosystems and sequester carbon but theirenvironmental effectiveness is not clear. We investigate program effectiveness and slippage in the context of Mexico's national payments for hydrological services program, which pays private and communal landowners to maintain forest cover on enrolled lands. To measure program impacts, we use matched controls drawn from the program applicant pool to establish counterfactual deforestation rates in the absence of payments.

Al igual que el resto de los países centroamericanos, El Salvador es altamente vulnerable a los efectos climáticos. En años recientes este país ha visto aumentar el número y la intensidad de los  desastres naturales, con sus altas repercusiones sobre la economía del país. Un sector que es  fundamental como proveedor de empleos y como impulsor del crecimiento económico es el agropecuario, el cual es altamente dependiente del clima y sobre él se han contabilizado grandes pérdidas ante los efectos climáticos.

El presente estudio estudio muestra cómo el cambio climático ocasiona reducciones en la producción, los rendimientos y el valor de la tierra de los agricultores de Nicaragua. Además, se cuantifica el efecto directo de las variaciones en temperatura  y precipitación sobre la producción, rendimientos y el valor de la renta de la tierra. El documento analiza algunos de los efectos potenciales del cambio climático sobre el sector agropecuario de Nicaragua.

El cambio climático representa una seria amenaza para las sociedades centroamericanas por sus múltiplesimpactos previstos en la población y en los sectores productivos. En términos fiscales constituye un pasivo público contingente que afectará las finanzas públicas de los gobiernos por varias generaciones.

Tenure in Mystery collates information on land under conservation, forestry and mining in the Karamoja region. Whereas significant changes in the status of land tenure took place with the Parliamentary approval for degazettement of approximately 54% of the land area under wildlife conservation in 2002, little else happened to deliver this update to the beneficiary communities in the region. Instead enclaves of information emerged within the elite and political leadership, by means of which personal interests and rewards were being secured and protected.

This paper updates an analysis of returns from major productive land uses in New Zealand carried out in 2008. Trends in profitability over time are shown, and a preliminary investigation of the relationship between land-use change towards forestry (new land planting) and forestry profitability is described.

El cambio climático representa una seria amenaza para las sociedades centroamericanas por sus múltiples impactos previstos en la población y en los sectores productivos. En términos fiscales constituye un pasivo público contingente que afectará las finanzas públicas de los gobiernos por varias generaciones. Se estima que para 2030 Centroamérica aún producirá menos de 0,5% de las emisiones de los gases de efecto invernadero (GEI) del planeta1 , pero al mismo tiempo ya es una de las regiones más vulnerables ante los embates del cambio climático.

A high-speed rail service can deliver competitive advantage over airlines for journeys of up to about 3 hours or 750 km, particularly between city pairs where airports are located far from city centres. One suitable type of corridor is that which connects two large cities 250-500 km apart. But another promising situation is a longer corridor that has very large urban centres located, say, every 150-300 km apart. On these longer corridors, typical of some being built in China, high-speed rail has the ability to serve multiple city-pairs, both direct and overlapping.

Includes land alienation in the case study sites; impacts of land alienation; coping strategies; conclusions and policy recommendations. Found that livestock numbers are declining dramatically in the area, land degradation is increasing, people are becoming more vulnerable to drought and famine, and resource-based conflicts are increasing in severity. The traditional pastoralist way of life is increasingly making way for sedentary farming and enclosed private grazing land.

The estimation of environmental sensibility to desertification at regional scale requires the setting up of elaboration and updating methodologies capable of handling considerable amounts of data in an integrated approach. This would allow evaluating the different stages of environmental degradation as well as the existing interactions among the singular components of the territory. These maps are also strongly related to climate conditions, land use changes and new data availability.

In developing countries, cities are rapidly expanding and urban and peri-urban agriculture (UPA) has an important role in feeding these growing urban populations; however such agriculture also carries public health risks such as zoonotic disease transmission. It is important to assess the role of UPA in food security and public health risks to make evidence-based decisions on policies. Describing and mapping the peri-urban interface (PUI) are the essential first steps for such an assessment.
