La synthèse qui en résulte indique la manière dont le changement climatique, la perte de biodiversité et la pollution peuvent être abordés conjointement dans le cadre des objectifs de développement durable. Le rapport a pour but de traduire l'état actuel des connaissances scientifiques en messages factuels clairs et digestes auxquels le monde peut se référer et comprendre.

Selon le WWF, La moitié des sites du Patrimoine mondial sont menacés par des activités industrielles

Selon le dernier rapport du WWF, 114 des 229 sites naturels et mixtes inscrits au Patrimoine mondial sont menacés par des activités industrielles néfastes. Concessions pétrolière, minière ou gazière, surpêche, exploitation forestière illégale, surexploitation des ressources en eau, infrastructures de transport ou de tourisme : les menaces sont nombreuses.

The Regional Assessment Report on Biodiversity and Ecosystem Services for Europe and Central Asia produced by the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) provides a critical analysis of the state of knowledge regarding the importance, status, and trends of biodiversity and nature’s contributions to people.

The Land Use Act of Nigeria, first enacted in 1978 was intended to simplify and standardise land administration systems across the country. It vested the authority to plan, assign and approve certificates of land ownership in the state governors, and all non-urban land in the local governments.

La région Tanger-Tetouan-Al Hoceima située au nord-ouest du Maroc a connu, dans des dernières décennies, différents travaux d’aménagement de territoire qui ont eu, certainement, un impact sur le paysage et l’écosystème de la région. La région a accueilli des infrastructures de grandes tailles telles que le port Tanger Med installé au bord du détroit Gibraltar, la ligne de train à grande vitesse reliant Tanger à Casablanca, réseaux routiers, barrages…etc. L’objectif de cet article est de cartographier les changements du paysage de la région via l’analyse diachronique de l’occupation du sol.

Artisanal and small-scale mining affects the quality and components of the environment in the Batouri area in different ways. Activities interfere with air, soil, water, fauna and forest resources. This study seeks to assess the impacts of mining on the environment using a combination of spatial analysis, questionnaires administration and Leopold’s grid of impact assessment. The impacts of mining on physical environment include air pollution by emission of dusts and fumes from engines, soil and subsoil degradation by earthworks and release of wastewater containing chemicals from companies.

Building on the current international discourse and United Nation's System of Environmental-Economic Accounting (SEEA) this study provides further empirical evidences on how failure to include natural capital resources in national accounting leads to erroneous calculation of macroeconomic estimates. The SEEA methodological framework for integrating natural capital into the System of National Accounts amplifies analytical power of computable general equilibrium (CGE) models and allows to investigate relationship between the economy and the environment.

Agri-environmental schemes have become an effective policy measure to prompt farmers to protect rural farmland and landscapes. In recent years, 17 provincial governments including Sichuan, Jiangsu, Shanghai, Guangxi and Guangdong have shown increasing interest in promoting local experimentation with agri-environmental schemes.

Colombia’s Andean-Amazonian foothills are among the most pressing deforestation hotspots in the country. Yet, the relationships and dependencies of underlying deforestation drivers are not well understood. For an adequate territorial reorganization in the post-conflict era that is sensitive to local context, a targeted analysis of the present situation at the local level is required. This study investigates direct and indirect deforestation drivers, relationships among these and potential measures to lower deforestation post-conflict.

This paper develops a framework for improved mainstreaming of ecosystem science in policy and decision-making within a spatial planning context. Ecosystem science is advanced as a collective umbrella to capture a body of work and approaches rooted in social-ecological systems thinking, spawning a distinctive ecosystem terminology: ecosystem approach, ecosystem services, ecosystem services framework and natural capital.

This research develops the novel concept of an economic ecosystem service sustainability index from the perspective of total income theory, and presents its empirical application at the spatial unit scale of the agroforestry farm. This paper compares the results accrued from applying the refined standard System of National Accounts (rSNA) and the authors’ Agroforestry Accounting System (AAS).

Although many contemporary studies of agriculture associate larger properties with higher relative productivity, this assumption has limited relevancy for the analysis of situations in which property owners profit more from large-scale property accumulation itself rather than any superiority in exploitation opportunities offered by increased size. In Brazil, the efficiency-of-scale paradigm has been used to criticize peasant agriculture as unproductive and hide contradictions deriving from land concentration.
