Natural rangelands occupy about 5.5 million hectares of Tunisia’s landmass, and 38% of this area is in Tataouine governorate. Although efforts towards natural restoration are increasing rapidly as a result of restoration projects, the area of degraded rangelands has continued to expand and the severity of desertification has continued to intensify. Any damage caused by disturbances, such as grazing and recurrent drought, may be masked by a return of favorable rainfall conditions.

According to the United Nations (UN) Refugee Agency, there were 79.5 million forcibly displaced people worldwide by the end of 2019. Evictions from homes and land are often linked to protracted violent conflict. Land administration (LA) can be a small part of UN peace-building programs addressing these conflicts. Through the lens of the UN and seven country cases, the problem being addressed is: what are the key features of fit-for-purpose land administration (FFP LA) in violent conflict contexts?

The importance of studying coastal areas is justified by their resources, ecosystem services, and key role played in socio-economic development. Coastal landscapes are subject to increasing demands and pressures, requiring in-depth analyses for finding appropriate tools or policies for a sustainable landscape management.

Historic urban landscapes (HULs) are composed of layers of history and memories that are embedded in physical monuments, buildings, and memorials. Physical built fabric stores both personal and cultural memory through long association with communities. Rapid changes due to demolition and redevelopment change the nature of these places and, in turn, affect these memory storages. This paper investigates whether historical city inhabitants consider cultural memories important when managing their HULs.

The Re-Greening of the West African Sahel has attracted great interdisciplinary interest since it was originally detected in the mid-2000s. Studies have investigated vegetation patterns at regional scales using a time series of coarse resolution remote sensing analyses. Fewer have attempted to explain the processes behind these patterns at local scales. This research investigates bottom-up processes driving Sahelian greening in the northern Central Plateau of Burkina Faso—a region recognized as a greening hot spot.

Desertification is defined as land degradation occurring in the global drylands. It is one of the global problems targeted under the Sustainable Development Goals (SDG 15). The aim of this article is to review the history of desertification and to evaluate the scientific evidence for desertification spread and severity. First quantitative estimates of the global extent and severity of desertification were dramatic and resulted in the establishment of the UN Convention to Combat Desertification (UNCCD) in 1994. UNCCD’s task is to mitigate the negative impacts of desertification in drylands.

Groundwater resources became a recognized enabler of important rural and socio-economic development in Mediterranean countries. However, the development of this groundwater economy is currently associated with an increased pressure on the available resource and negative implications on the socio-ecological system. Managing complex socio-ecological systems, such as those that occur in water resource management, is a multi-actor, multi-scale and dynamic decision-making process.

Endemic species on mountains often have narrow altitudinal ranges and are more threatened at the higher altitudes, especially with climate changes. However, plants could use special microhabitats at the mountain tops as proper places for surviving the climate change (i.e., refugia). We assessed population attributes of three critically endangered endemic species (Primula boveana Decne ex Duby, Rosa arabica Crep., and Silene leucophylla Boiss.) in two growing seasons (2006/2007 and 2013/2014), differing in the received rainfalls in microhabitats at the high mountains of southern Sinai.

Abu Dhabi, the capital city of the United Arab Emirates (UAE), is one of the pioneering cities in the Middle East and North Africa (MENA) region that have recently prepared urban sustainability agendas for their cities. Nonetheless, the recently developed urban neighborhoods in Abu Dhabi mostly rely on Land Use planning and their urban forms are still missing essential sustainability qualities.

Ecosystem services (ESs) are increasingly being used by many countries around the world as a framework for addressing the United Nations (UN) Sustainable Development Goals (SDGs). This review article of the usability of Libyan soil databases for ESs and SDGs is the first of its kind for North Africa.
