“…Desertification is activated by climate change, inducing water scarcity and land degradation. The recent negative impacts of climate change are confirmed in multiples oases over the world (Imaz-Lamadrid et., 2020). Verstraete et al (2008) consider climate change to be a factor in the future degradation of drylands.…”

The study apprehends modern versus traditional land-use changes in the Moroccan oases. The traditional local knowledge and land-use that ensured ecological equilibrium for centuries is decreasing. Modern entrepreneuship practices are increasing and have risky environmental impacts. By using the spatial and factor analyses, we confirm the spatial disparities in the region and distinguish four different groups of communes (in high mountain communes, traditional agriculture favors resources’ conservation; downstream communes experience greater changes and ecological ruptures). The recommendations of the study include the need to rethink adopted development models and elaborate new actions that respect local specificities, consider environmental equilibrium and rehabilitate local ecosystems.

“…Similarly, oasis expansion was also found in the arid areas of other countries in the past few decades, such as the oasis in the Manas River Basin [6], the middle reaches of the Qinghai Tibet Plateau [7], and Al-Aba Oasis (Kingdom of Saudi Arabia) [8]. Especially, the area of artificial oases dominated by cultivated land and construction land has increased, such as the oasis of Middle Draa Valley (Morocco) [9] and Todos Santos Oasis (Mexico) [10]. The oasis expansion provides more opportunities for human survival and development [11].…”

“…In recent years, researchers have carried out a lot of research on the spatial and temporal changes of the oasis in arid zones [7][8][9][10][11][12][13][14][15][16][17][18], greatly advancing our knowledge on the vegetation coverage change [19], land use change [11], landscape pattern of oasis [20], the driving forces of oasis change [4], oasis stability [21], and oasis land-use change prediction [17]. The research areas of the oasis in China are mostly concentrated in the main distribution areas of the oasis such as Xinjiang [22,23] and the Hexi Corridor of Gansu Province [24][25][26][27].…”

Oasis Change Characteristics and Influencing Factors in the Shiyang River Basin, China

et al. 2022

The variability of the natural environment and the complexity of human activities result in dynamic changes in oasis areas, which is directly related to the sustainable development of arid and semi-arid areas. In order to better balance economic development and environmentally sustainable development, based on land use data and social and economic data from 1980 to 2015, this paper analyzed the oasis change characteristics under natural and human factors in the Shiyang River Basin in Northwest China. The results indicated that the oasis in the Shiyang River Basin showed an expansion trend from 1980 to 2015, with the expansion mainly occurring in the diluvial and alluvial fan, and along the middle and lower reaches of the river. The oasis changed actively in areas at an elevation of 1350 m, with a slope of 2°, at the distance of 1500 m to rivers, and with precipitation of 120 mm and temperature of 15 °C. Furthermore, the oasis mainly evolved towards gentler slopes and lower altitudes, and migrated closer to rivers before 1992 and farther away from rivers afterwards. Population growth and economic development were the important inducers of oasis change, and government policies on agricultural benefits and ecological conservation also influenced the oasis change, especially after 2000. The evolution patterns of oasis distribution revealed in this study can provide a reference for promoting oasis ecological restoration and sustainable development.

“…The average annual rainfall is 200 mm/year in the valley and over 400 mm/year in the mountainous area [40]. Summer rains tend to be of great intensity and short duration, especially in August and September [41], due to the approach of tropical cyclones to the southern part of the Baja California Peninsula [42][43][44]. La Paz is also a municipality that is one of the most frequently impacted by tropical cyclones, with a return period of 5.6 years for category 1 hurricanes (according to the scale Saffir-Simpson) [27,45].…”

Integrated Runoff-Storm Surge Flood Hazard Mapping Associated with Tropical Cyclones in the Suburbs of La Paz, Baja California Sur, México

Floods are amongst the most frequent and destructive type of disaster, causing significant damage to communities. Globally, there is an increasing trend in the damage caused by floods generated by several factors. Flooding is characterized by the overflow of water onto dry land. Tropical cyclones generate floods due to excess water in rivers and streams and storm surges; however, the hazard of both phenomena is presented separately. In this research we present a methodology for the estimation of flood hazards related to tropical cyclones, integrating runoff and storm surge floods. As a case study, we selected the south-western suburbs of the city of La Paz, the capital of the state of Baja California Sur in northwest Mexico. The city has experienced in recent years an expansion of the urban area. In addition, there is an infrastructure of great importance such as the transpeninsular highway that connects the capital with the north of the state, as well as the international airport. Our results indicate that urban areas, agricultural lands, as well as the air force base, airport, and portions of the transpeninsular highway are in hazardous flood areas, making necessary to reduce the exposure and vulnerability to these tropical cyclone-related events. A resulting map was effective in defining those areas that would be exposed to flooding in the face of the impact of tropical cyclones and considering climate change scenarios, which represents an invaluable source of information for society and decision-makers for comprehensive risk management and disaster prevention.
