El propósito de este artículo es explorar algunas consideraciones basadas en el criterio de la eficiencia económica pura; necesarias para diseñar una política pública eficiente para la de asignación de activos ambientales de interés público. Se presenta una versión del modelo de Fisher y Krutilla para estudiar el problema de asignación óptima de recursos naturales bajo conflictos del uso entre conservación y desarrollo. El modelo se aplica a un estudio de caso para determinar el mayor y mejor uso de un ambiente natural urbano en Bogotá; Colombia.

Food cannot be grown without water. In Africa, one in three people endure water scarcity and climate change will make things worse. Building on Africa’s highly sophisticated indigenous water management systems could help resolve this growing crisis, but these very systems are being destroyed by large-scale land grabs amidst claims that Africa's water is abundant, under-utilised and ready to be harnessed for export-oriented agriculture.

The focus of the project is on increasing the resistance of the physical environment to landslide activity; and building capacity of the community to decrease their vulnerability to landslides when they do occur. Project activities will include: 1. Identifying critical points of erosion and deforestation in Macacos Hill; 2. Promoting Reforestation of Macacos Hill, with the help of residents; 3.

This policy brief by the Asian Development Bank argues that, given the negative impact of climate change on Mongolia, it is crucial to select mitigation actions that reduce vulnerability to climate change, support the achievement of national development goals, and are feasible given local constraints.

Key messages from the brief include:

• Mongolia’s total emissions are low, but its emissions per capita are relatively high and rising and are produced primarily by the energy and agriculture sectors.

Ever since colonial administrators and western trained scientists became involved in sub-Saharan Africa in the early 20th century and were faced with the task of governing countries where livestock production was a major economic enterprise, the proper utilisation of rangelands became a major concern. While during most of the colonial era devastating epidemics (like rinderpest and pleuropneumonia) kept the growth of livestock populations in check, during the 1950s and 1960s regional campaigns of eradicating these major cattle diseases created a continuous increase in livestock numbers.

This paper presents possible elements of a long-term international vision for land sector reporting and accounting. The vision is of a multi-dimensional land sector reporting and accounting framework that is applicable to all countries and increases in comprehensiveness over time. The overarching objective of the framework is to build trust between Parties to the United Nations Framework Convention on Climate Change (UNFCCC) by tracking progress in implementation of mitigation contributions in the land sector.

This study investigates attitudes towards legalizing land sales and Willingness to Accept (WTA) sales prices and compensation prices for land among smallholder households in four different areas in the Oromia and SNNP Regions in the southern highlands of Ethiopia.

Household panel data from 2007 and 2012 are used. The large majority of the sample prefers land sales to remain illegal, and the resistance to legalizing land sales increased from 2007 to 2012. In the same period, perceived median real land values increased sharply but also exhibit substantial local variation.

Land-use and land-cover change (LULCC) represents one of the key drivers of global environmental change. However, the processes and drivers of anthropogenic land-use activity are still overly simplistically implemented in Dynamic Global Vegetation Models

Land and decentralisation policies in Senegal have been closely linked since the country became independent in 1960. Although local governments manage public lands and participate in the management of special areas, the actual degree popular participation in land and decentralisation policies occurs strongly depends on the rights granted to local communities and governments and the available human and financial resources. This paper explores these issues and discusses their effect on decentralisation and land management in Senegal.

This review explores environmental change in northern and south-central Kenya, roughly covering three decades from the 1960s to the 1990s. The report answers three questions:has vegetation change occurred in these districts?if vegetation change has occurred, why and how has this happened?what are the trends for livestock populations?The article concludes that:rangeland sites have been fundamentally altered by woody encroachment over the past 40 years.

There is a general consensus among academics, politicians and social movements, that BRICS as ‘new donors’ are increasing both their quantitative and qualitative role in defining what is considered to be ‘the world economic order’.

This report highlights the potentially significant impacts on the hydrologic cycle and the importance of considering secondary effects, particularly with regard to water, resulting from the widespread adoption of global climate change mitigation measures. It is recommended that the implicit hydrologic dimensions of climate change mitigation should be more formally articulated within the international environmental conventions, and recognized within future UNFCCC negotiations on the CDM-AR provisions.
