“…In recent years, alternative regimes (Scheffer et al, 1993;Scheffer and Van Nes, 2007;Yan et al 2021) have emerged as one of the more relevant theories to indicate the critical threshold level of nutrients in the shift to a turbid state . The indication of this theory's main elements by the inhabitants of the Rio Direito showed us the relevance of traditional knowledge incorporation between generations, revealing sophisticated technical expertise and potentially applicable to rock pool conservation.…”

In northeastern Brazil, the drought history has been well documented, reflecting a resilient population with a robust regional identity. Last year, in response to the need to perpetuate water access and reduce scarcity, the Brazilian government implemented a program called the Program One Million Cisterns (P1MC). Considering that the need for water resource perpetuation can impact traditional knowledge transmission between generations, this study aimed to analyze the knowledge regarding rock pools in a small village located in a semiarid region in Brazil. The interviews addressed questions about the traditional knowledge, use, and management of rock pools. The abiotic and biological water variables were collected to establish the population's knowledge status. Our results identified that the use and management of rock pools were reduced after implementing P1MC. Despite the historical relevance of these ecosystems, their use was abandoned by most of the inhabitants, except for domestic use. Therefore, the transmission of traditional knowledge regarding rock pools have decreased between generations, compromising hydric security and representing a serious socioeconomic risk for a region characterized by extreme droughts.

Africa is the cradle of the world’s giraffe species and the sub-species that keep evolving with more conservation approaches. However, the population of Rothschild’s Giraffe (Giraffa camelopardalis rothschildi) has been impacted at different sects in the wild. The aim of this paper was to review the status of Rothschild’s giraffe in Africa. A desktop descriptive review approach was used through perusal of different scholarly articles on giraffes. From the existing literature, this review exposes the effect of human effects on giraffes, climate change extremes on wildlife, ecological and significance of wildlife, and socio-economic impacts of communities on giraffes. The existing literature shows the impact of climate change extremes on giraffe habitats, with notable droughts, triggers of diseases, and unfit habitat migrations. Conservation of wildlife has to deal with socio-economic and ecological issues that are complex and, most of the time, overwhelming. We recommend the need for community engagement in conservation of wildlife resources and the development of climate prediction models to better understand climate extremes that happen and affect giraffe habits and population.

“…Lakes are essential elements for conserving water sources, purifying water quality, regulating ecological environments, and protecting biodiversity in semi-arid regions [1][2][3][4]. Due to low precipitation and intense evaporation, lakes in such regions are sensitive to environmental changes, and recovery from damage is difficult [5][6][7]. Over the past few decades, climate warming and human activities have significantly affected the water supplement and consumption of lakes in semi-arid regions, resulting in the shrinkage or disappearance of lakes, increased salinization, and changes in local ecosystems [8][9][10].…”

Analysis of Detailed Lake Variations and Associated Hydrologic Driving Factors in a Semi-Arid Ungauged Closed Watershed

Lakes are key factors in maintaining ecosystems in semi-arid regions. However, due to data shortage, most studies used remote-sensing data and water-balance models to analyze lake variations in semi-arid ungauged closed watersheds, resulting in the oversimplified assessment of lake variations and their associated hydrologic processes. This study aimed to enhance the understanding of the mechanisms behind the water supplement and consumption of lakes and reveal the influences of hydrological processes on lake variations in such watersheds. Physically based and lake-oriented hydrologic modeling, remote-sensing technology, and results from previous studies were comprehensively integrated to achieve the research objective. The Hongjiannao (HJN) watershed in Northwest China was selected as the study area of this research. The calibration and validation results demonstrated that remote-sensing data and results from previous studies indeed guaranteed the accuracy of the lake-oriented model. Further hydrologic and statistical analyses revealed the linkage between lake variations and their associated hydrologic processes, and the mechanisms behind the linkage. Specifically, rainfall and snowmelt were found to be the most stable sources of HJN Lake, particularly in dry years. Due to the differences in recession rates, groundwater inflow was more stable than upstream inflow and inflow from the contributing area of HJN Lake. The correlations between hydrologic processes and the storage variation of HJN Lake varied significantly at daily and monthly time scales, which can be explained by the generation mechanisms of these processes. This study provided valuable guidance for water resources management and ecosystem protection in the HJN watershed and can be further applied for hydrologic simulations in other similar watersheds.
