The intensity and frequency of drought periods increased after the 1990 s, especially as measured by the SPEI. Additionally, the results of the present study indicate an increase in the intensity and frequency of dry periods, which is associated with climate change. In the study area, climate change is characterised mainly by an increase in air temperature (0.17–0.39 °C/10 years). The SPEI index is more sensitive to changes in the water balance, as it takes into account the influences of both precipitation and evaporation, in contrast to the SPI index, which considers only the influence of precipitation. Consequently, when drought conditions are analyzed using the SPEI index, a more accurate representation of the depth and severity of drought is obtained. These findings have important implications for the development of adaptation measures in agriculture and water management in the context of increasing drought risk in the Southern Pre-Balkash region.</div></div>","PeriodicalId":101280,"journal":{"name":"Watershed Ecology and the Environment","volume":"7 ","pages":"Pages 11-22"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143158893","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite their importance, global fluctuations in wetland distribution highlight the need for accurate and comprehensive mapping to address current and future challenges. In Argentina, a lack of detailed knowledge about wetland distribution, extent, and dynamics impedes effective conservation and management efforts. This study addresses these challenges by presenting a probabilistic wetland distribution map for Argentina, integrating 20 years of satellite imagery with machine learning and cloud computing technologies. Our approach introduces a comprehensive set of biophysical indices, enabling the identification of key wetland characteristics: 1) permanent or temporal surface water presence; 2) water-adapted vegetation phenology; and 3) geomorphology conducive to water accumulation. Our model achieved an accuracy of 89.3 %, effectively identifying wetland areas and delineating “elasticity” zones that reveal temporal wetland behavior. Approximately 9.5 % of Argentina is classified as wetlands, with the Chaco-Mesopotamia region accounting for 43 % of these areas. The performance of the 42 assessed variables varied across macro-regions, highlighting the necessity for region-specific classification methods. In the Andean region, variables such as the Digital Elevation Model (DEM) and Topographic Wetness Index (TWI) were key predictors, while in the plains, spectral properties including vegetation and water content indices were more significant. Despite challenges in classifying irrigated areas, the model demonstrated considerable robustness. This study not only enhances our understanding of wetland dynamics but also provides insights into how different regions respond to various environmental factors, offering a more nuanced perspective on wetland behavior. These findings pave the way for refined conservation strategies and further research into the impacts of climate change and land use on wetland ecosystems. The precision, scalability, and representation of wetland elasticity emphasize its importance for decision-making and provide a crucial baseline for future research amid ongoing environmental changes.</div></div>","PeriodicalId":101280,"journal":{"name":"Watershed Ecology and the Environment","volume":"7 ","pages":"Pages 144-158"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143816973","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The findings highlight that Ethiopia, with a longstanding history of environmental protection practices such as establishing protected areas, soil and water conservation, and sanitation, has made notable progress, especially since the mid-1990s. The inclusion of environmental rights in the 1995 Constitution led to the development of comprehensive policies, strategies, proclamations, regulations, and guidelines for sustainable development. Despite these advancements, Ethiopia faces numerous environmental challenges, including land degradation, climate change, deforestation, pollution, and inadequate implementation of environmental policies. These issues are further complicated by political instability, financial constraints, a lack of skilled human resources, rapid population growth, traditional agricultural practices, and weak community awareness. However, opportunities for improvement exist. Ethiopia can enhance its environmental goals by utilizing hydropower, investing in solar and wind energy, promoting sustainable agriculture, and accessing international climate finance. Nevertheless, the actions taken by the government and individuals have been inconsistent and scattered, leading to unsuccessful efforts to achieve sustainable development. Moving forward, addressing these persistent challenges requires coordinated efforts, political stability, innovative solutions, and public involvement.

After 2003, significant changes occurred in the “river-lake relationship” between Poyang Lake and the Yangtze River, with intensified dry conditions in autumn and winter leading to a shortened inundation period for sandbanks and significant changes in the community structure and spatial distribution of wetland vegetation. By coupling a Gaussian model with a population dynamics model, this study simulated the response of wetland vegetation to inundation duration under different hydrological year types, revealing the relationship between vegetation distribution and inundation duration. Key parameters, such as growth and mortality rates, were identified, and the vegetation succession and spatial distribution of Poyang Lake wetlands were simulated for five representative years: a wet year (2010), a normal year (2001), a dry year (2006), an extreme wet year (1998), and an extreme dry year (2022). The results showed that the response of wetland vegetation to inundation duration followed a Gaussian curve, with each species exhibiting an optimal range of inundation durations. Mortality rates increased when the duration fell outside this range.

An integrated GIS-based DRASTIC model approach incorporating well logs, precipitation records, geological maps, and land use data assessed and mapped climate-LULC interactions on vulnerability zones across the basins. Results demonstrate significant spatiotemporal variability, with 32 % of the area classified as moderately vulnerable, while high (23 %) and very high (17 %) vulnerability zones concentrate predominantly in the Ankobra Basin, particularly near mining towns like Prestea, Tarkwa, and Bibiani.

Very low vulnerability areas may expand across all periods (near, mid, and far future), while high and very high zones could decline by 9.58 % and 11.93 % respectively by the far future. The findings highlight the need for targeted strategies in mining-affected areas, including stricter environmental regulations, groundwater protection zones, and sustainable land management.

Roadside curb inlets are key components of grey infrastructure that convey stormwater to various drainage systems. Curb inlets for conventional drainage systems are typically long, whereas they are usually shorter for directing stormwater to sustainable green stormwater infrastructures (GSIs), such as a roadside bioretention cell. As shorter curb inlets drain stormwater to GSIs, they have noteworthy advantages over conventional inlets such as environmental sustainability, urban flood resilience, pollution control, improved public health, and mitigating urban heat stress. This perspective aims to present a global outlook on the implementation of sustainable GSI curb inlets while also exploring the transition from conventional to sustainable systems. While some countries such as the USA, Canada, and China have adopted sustainable drainage practices including curb inlets, most regions, such as South Asia, Central America, and Africa are still far from embracing these practices. For the wider implementation of sustainable curb inlets with GSIs, recommendations include framing policies at the ministry level, raising awareness through research institutes, and educating the public on the benefits of sustainable drainage. For efficient design, it’s crucial to understand curb inlet hydraulics, consider various design parameters, monitor for clogging and sediment buildup, and account for climate change impacts.</div></div>","PeriodicalId":101280,"journal":{"name":"Watershed Ecology and the Environment","volume":"7 ","pages":"Pages 199-207"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143934926","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
