Este trabajo tiene por objetivo el análisis de la calidad del agua del arroyo Langueyú para determinar el estado de situación y su relación con la gestión de los recursos hídricos superficiales a nivel local. Se tuvieron en cuenta antecedentes hidrológicos regionales. Se efectuaron recorridos siguiendo el cauce del arroyo desde la cuenca alta, al Sur de la ciudad de Tandil incluyendo sus tributarios Blanco y Del Fuerte, hasta la intersección con la Ruta Provincial Nº 30. Se seleccionaron 9 sitios en los que se realizaron muestreos de calidad de agua en el período 2009-2011.

A Amazônia brasileira, que detém grande parte da maior floresta tropical do mundo, está ameaçada pela exploração descontrolada de seus recursos naturais. Mais de 750.000 km² de florestas já foram desmatados por atividades econômicas em escala industrial como a produção agropecuária, mineração, exploração ilegal de madeira e grandes projetos de infraestrutura, especialmente usinas hidrelétricas –, colocando em risco a biodiversidade incomparável da região, forçando o deslocamento de comunidades tradicionais e povos indígenas de suas terras e agravando as mudanças do clima global.

Safeguarding the world’s remaining forests is a high-priority goal. We assess the biophysical option space for feeding the world in 2050 in a hypothetical zero-deforestation world. We systematically combine realistic assumptions on future yields, agricultural areas, livestock feed and human diets. For each scenario, we determine whether the supply of crop products meets the demand and whether the grazing intensity stays within plausible limits. We find that many options exist to meet the global food supply in 2050 without deforestation, even at low crop-yield levels.

Framework and Guiding Principles for a Land Degradation Indicator to monitor and report on progress towards target 15.3 of the Sustainable Development Goals, the strategic objectives of the Rio Conventions and other relevant targets and commitments

The city of Dar es Salaam, Tanzania has undergone a period of unprecedented urbanization that has contributed to the degradation of the city’s natural environment. With a growth rate above or near 5% for the past three decades, it is the fastest growing city in East Africa. The arrival of thousands of in-migrants year after year has overwhelmed the city’s ability to deliver adequate public services, housing and jobs. Unplanned, densely populated informal settlements that lack basic water, sewer, and waste services now cover much of the city’s land area.

The study assessed the socio-economic impact of the project supported by UNDP and the Government of Madhya Pradesh to support local communities in rehabilitating degraded forest, generating sustainable livelihoods and protecting the areas rich ecosystem. The project was supported by the Global Environment Facility.

Le présent décret détermine la procédure de délivrance des actes d’urbanisme. Ces actes sont constitués des décisions des autorités publiques compétentes qui autorisent la réalisation d’opérations immobilières (certificat d’urbanisme, du permis de construire, de la déclaration de travaux et du certificat de conformité) qui consacrent des règles d’urbanisme, de construction, d’hygiène, de protection de l’environnement, de l’habitat et de sécurité incendie. En outre, Il organise un régime de répression des violations du règlement d’urbanisme.

Despite their ecological, economic and social importance, Mediterranean grasslands continue to receive limited scientific, political and media attention. Grasslands are typically viewed as underutilized space, able to be transformed into more “valuable” land by placing it under cultivation, transforming it into forest land and/or privatizing it. This paper synthesizes a number of pertinent issues in relation to social and economic systems on grasslands within the southern Mediterranean region.

Land degradation is a major challenge for agricultural and rural development
in Uzbekistan. Our research findings indicate that the costs of land
degradation in Uzbekistan are substantial; reaching about 0.85 billion USD annually
resulting from the loss of valuable land ecosystem services due to land use and
land cover changes alone between 2001 and 2009. On the other hand, economic
simulations also show that the returns from actions to address land degradation can
be four times higher their costs over a 30-year planning horizon, i.e. every dollar

At the request of the Sri Lankan Government an assessment was designed and conducted as part of the development of the country’s national strategy on REDD+.  The assessment involved applying criteria from the Voluntary Guidelines on the Responsible Governance of Tenure of Land, Fisheries, and Forests (VGGT) to analyze the tenure implications for a wide array of proposed policies and measures (PAMs) to address deforestation and forest degradation.  The assessment will help Sri Lanka to prioritize and make investment decisions among the PAMs.
