The paper analyzes the state and dynamics of key actors and institutions that regulate the use of resources within the protected areas of the North Caucasus, using the examples of the Teberda Biosphere Reserve and the Elbrus National Park. The network of protected areas created in the North Caucasus during the Soviet period relied on government support, and the participation of the local population in nature conservation was very limited. After the collapse of the Soviet Union and the demonopolization of state land laws, new actors emerged, such as the local population and business.

Rural community tourism initiatives in developed nations share most positive and negative characteristics with community-based tourism (CBT) initiatives in developing nations. They also share many barriers and conditions for tourism development. What makes them different is the context in which they operate. This paper identifies the main conditions that explain these differences through a review of findings from 103 location-specific case studies and other available literature that provides empirical evidence. The paper also explores the usage of the concepts of CBT and rural tourism.

For almost two decades, the Lake Chad Basin (LCB) in general and northeast Nigeria in particular have been subject to the insurgency of the Islamist terrorist group Boko Haram. This region is also known for its poor environmental conditions that mostly manifest in land desertification and water scarcity. We analyze the impact of the insecurity and conflict on migration from the most affected rural areas of northeast Nigeria to Maiduguri. We also explore the role that water scarcity and land desertification play in the decision of local people to migrate.

Land degradation affects a significant portion of the Earth’s ice-free land area and several countries have embraced the challenge of restoring large parts of their degraded lands. Success in these efforts depends on various factors, including the amount of resources invested, the technical capacity available and the degree of involvement of stakeholders. Burkina Faso has committed to restoring 5 Mha of degraded land by 2030.

Climate change has strong impacts on soil conservation and agricultural productivity, with severe consequences on smallholders in developing countries, but virtually no research has been carried out so far on this issue. Therefore, it is necessary to foster the implementation of participatory projects to help communities deal with new difficulties. Sustainable soil management can reduce and even reverse land degradation, helping farmers to adapt to climate change effects.

Understanding the interactions of the social and biophysical drivers of land degradation is crucial for developing adaptive management actions for future sustainability. A research-praxis project, the ‘Tsitsa Project’ (TP), applies a social-ecological systems (SES) approach where researchers, natural resource managers, and residents collaborate to support sustainable livelihoods and improved natural resource management for the degraded Tsitsa River Catchment (TRC) in South Africa.

Mapping and quantifying land degradation status is important for identifying vulnerable areas and to design sustainable landscape management. This study maps and quantifies land degradation status in the north Gojjam sub-basin of the Upper Blue Nile River (Abbay) using GIS and remote sensing integrated with multicriteria analysis (MCA). This is accomplished using a combination of biological, physical, and chemical land degradation indicators to generate a comprehensive land degradation assessment.

Wind erosion desertification is the most serious type of land degradation in Northwest China, so it is an important task for ecological management in the region. As the core of ecological management, soil quality is mainly affected by the presence of silt–clay content. Therefore, the grasp of its occurrence regularity is the key to controlling wind erosion desertification. At present, research on silt–clay contents is mainly independent in each local area and lacks integrity, which makes it difficult to meet the overall evaluation and planning requirements.

Widespread interference of human activities has resulted in major environmental problems, including pollution, global warming, land degradation, and biodiversity loss, directly affecting the sustainability and quality of the environment and ecosystem. The study aims to address the impact of the extraction of natural resources and globalization on the environmental quality in the South Asian countries for the period 1991–2018. A new methodology Dynamic Common Correlated Effects is used to deal with cross-sectional dependence.

Land desertification is a global environmental problem, leading to the deterioration of the ecological environment and is an issue that threatens humans. Hongsibu, located in Ningxia, northwest China, is a semi-desert area with the largest domestic single-site ecological resettlement area for poverty alleviation based on the wine industry. Here, we quantified the value of the ecosystem services of the wine industry in Hongsibu and used the analytic hierarchy process (AHP) to quantitatively evaluate the comprehensive benefits of the wine industry for resolving desertification.
