Esse relatório apresenta as conclusões da análise custo-benefício para garantir a proteção das áreas florestais

indígenas na bacia amazônica da Bolívia, Brasil e Colômbia. Esses países foram selecionados principalmente

porque incluem uma significativa porção da bacia da Floresta Amazônica e seus governos reconhecem

formalmente várias terras indígenas. A pesquisa tem por base o documento de trabalho recentemente publicado

pelo WRI, Os custos e benefícios econômicos da proteção da posse de comunidade florestal: Evidências do Brasil

Les terres arides couvrent près de la moitié de la surface terrestre et abritent un tiers de la population mondiale. Elles sont confrontées à des défis hors du commun, notamment ceux posés par la désertification, la perte de biodiversité, la pauvreté, l’insécurité alimentaire et les changements climatiques. Quelque 20 pour cent des terres arides de la planète sont dégradées, et les personnes qui vivent sur ces terres sont souvent piégées dans un cercle vicieux de pauvreté, pratiques destructrices et détérioration de l’environnement.

La publication contribuera à la sortie 3 du plan de travail du Mécanisme de la restauration des forêts et des paysages (RFP) 2015-2016 (par exemple, la poursuite du développement / mise en œuvre des efforts RFP aux niveaux mondial / régional est pris en charge par la gestion des connaissances, la communication et la sensibilisation - mobilisation de ressources financières pour la RFP)

The Conference of the Parties (COP) of UNFCCC is a prime opportunity to communicate FAO’s work on climate change and to liaise with potential partners, at the numerous side events and parallel events organized around the COP. This booklet seeks to raise awareness on the impacts of climate change on food security and nutrition and advocate for the importance of having the agricultural sectors properly considered in climate change mechanisms, policies and finances.

These guidelines are the result a consultative process that involved a large number of practitioners from both developed and developing countries. Two meetings were held in Glasgow and Delhi and a tentative outline was agreed upon. The guidelines are intended to provide a reference framework for decision makers and planners to adequately plan, design and manage the forest and trees in and around their cities.

As atividades relacionadas à produção agrícola estão entre as que mais têm gerado impactos sobre o meio ambiente. A produção intensiva é grande consumidora de energia, além de fonte de contaminação da água, ar e solo, por meio, especialmente, de resíduos de pesticidas e de fertilizantes. A expansão das fronteiras agrícolas aumenta as taxas de desmatamento, agrava os processos de degradação do solo e põe em risco a biodiversidade.

The poverty and environmental degradation vicious circle hypothesis considers the poor as agents and victims of environmentally degrading activities. Despite some studies, however, there still has not been a sufficient empirical examination of the poverty-environment nexus.

This research examines the impact of forest management regimes, with various degrees of restriction, on forest conservation in a dry deciduous Indian forest landscape. Forest change is mapped using Landsat satellite images from 1977, 1990, 1999, and 2011. The landscape studied has lost 1478 km2 of dense forest cover between 1977 and 2011, with a maximum loss of 1002 km2 of dense forest between 1977 and 1990. The number of protected forest areas has increased, concomitant with an increase in restrictions on forest access and use outside protected areas.

New England forests provide numerous benefits to the region’s residents, but are undergoing rapid development. We used boosted regression tree analysis (BRT) to assess geographic predictors of forest loss to development between 2001 and 2011. BRT combines classification and regression trees with machine learning to generate non-parametric statistical models that can capture non-linear relationships.

The nature and significance of China's engagements with African agriculture continues to be hotly debated in the media, academia and policy circles around the world. Although China has been engaged in Uganda’s agriculture for more than 40 years, the recent jostle for agricultural land by private Chinese investors is dystifying and justifies the need to conduct a scientific study to provide clear evidence before the issue gets bundled into the messy anecdotal media inquiry.
