Land degradation has become one of the major global environmental problems threatening human well-being. Whether degraded land can be restored has a profound effect on the achievement of the 2030 UN Sustainable Development Goals. Therefore, the ways by which to identify the current research status and potential research topics in the massive scientific literature data in the field of land degradation is a crucial issue for scientific research institutions in various countries.

This study investigates the main threats related to environmental degradation that affect Amazonian Indigenous Lands (ILs). Through a cluster analysis, we group ILs according to the set of common environmental threats that occur within and outside their limits. The results show that most of the 383 ILs are affected internally by a combination of different environmental threats, namely: deforestation, forest degradation, fires, mining, croplands, pastures, and roads.

Aujourd’hui, la périurbanisation est reconnue comme un phénomène mondial animée par différents déterminants (poussée démographique, développement industriel, crise de la ruralité, etc.). En effet, les territoires périurbains sont des espaces qui reçoivent l’excédent de la croissance démographique urbaine et qui accueillent les nouveaux projets d’aménagement et de développement (promotions immobilières, implantations de zones d’activités diverses, développement des réseaux de communication, maintien ou développement de certaines agricultures, etc.).

La pandémie de Covid-19 est sans aucun doute l’événement majeur de santé publique qui a marqué les êtres humains, les sociétés et les esprits dans le monde entier et particulièrement l’Afrique. Tous les gouvernements ont adopté des mesures de santé publique, notamment le confinement et d’autres mesures exceptionnelles dans le cadre de l’état d’urgence sanitaire, pour réduire la propagation du virus. La chute soudaine de l’activité humaine a des conséquences sur l’environnement, et l’utilisation/exploitation des ressources naturelles, notamment la pêche.

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.

Environment statistics enumerate various aspects of the environment and human interactions with it. The scope of environment statistics encompasses all dimensions of the environment, be it Earth, Water or Air, the biotic and abiotiv matter found within the natural environment, and various concerns arising out of impacts of human footprints on it. The objective of environment statistics is to provide information about the environment, its changes over time and across locations, and the main factors that influence them.

Indicator 15.3.1: Proportion of land that is degraded over total land area
 

The habitat of the several territories in Ciudad Real (Castilla-La Mancha, Spain) are studued through the and mapping (scale 1:10.000) and vegetation analysis. The distribution and surface of the habitat presents in the Sites of Community Interest (SCIs), as well as pressures, threats, trends, and state of conservation are described. These site contributes significantly to the maintenance or restoration at a favourable conservation status of a natural habitat type or of a species of community intesess.These specially protected areas are part of the Natura 2000 network.

The establishment of rural settlements in the topographically complex mountainous area of South-Western China is restricted by various geographical features. The fractal characteristics and water-facing distribution of rural mountain settlements and the suitability of spaces for rural mountain settlements were analyzed for a greater scientific understanding of what factors would facilitate a more appropriate selection of residential sites.

Urbanization is changing land use–land cover (LULC) transforming green spaces (GS) and bodies of water into built-up areas. LULC change is affecting ecosystem services (ES) in urban areas, such as by decreasing of the water retention capacity, the urban temperature regulation capacity and the carbon sequestration. The relation between LULC change and ES is still poorly examined and quantified using actual field data. In most ES studies, GS is perceived as lumped areas instead of distributed areas, implicitly ignoring landscape patterns (LP), such as connectivity and aggregation.
