Summary: This study quantified the impacts of climate change and agricultural management adaptation on irrigated agriculture in the Indus basin. The results show that by the 2030s, improved nutrient availability and constrained irrigation can achieve sustainable and increased agricultural production. However, by the 2080s, the productivity will strongly depend on worldwide climate-change mitigation efforts.

Summary: The expansion of irrigated croplands has significantly boosted global agricultural productivity throughout the 20th century. However, limited progress has been made in sub-Saharan Africa due to under-delivery of irrigation schemes and policies. This study focuses on the Senegal River Valley, mapping the distribution of croplands under active irrigation between 1986 and 2020. The research reveals two distinct periods of irrigation development, with a stagnant phase until 2008 followed by a boom phase.

Summary: This study investigates the impact of pumping reductions on aquifers and how much data is needed to reliably predict this impact. The results show that accurate estimates of key parameters can be obtained with much sparser data than available in highly data-rich aquifers like the High Plains aquifer in Kansas, as long as the data are not systematically biased.

Summary: Comprehensive information on the past trend of local-level water usage of cultivated crops is important for agricultural planning. However, such information is lacking for the North-West region of Bangladesh. The study found significant decreasing trends in ET for Rabi crops and cropping patterns in all districts, as well as an increase in total volumetric quantities of water due to expanded irrigated area over time.

Summary: The application of excessive nitrogen fertilisers can lead to nitrate contamination in groundwater, which can impact surface water quality. This study in the Emerald Irrigation Area, Australia, investigated the occurrence and controls of denitrification in nitrate-rich aquifers. The results showed that denitrification primarily occurs in anaerobic zones and beneath leaking irrigation channels, leading to significant nitrate reduction. Understanding regional and local hydrogeological processes is crucial for assessing the impacts of nitrate contamination on adjacent ecosystems.

Summary: Traditionally, topographic depressions in Digital Elevation Models (DEMs) were considered as artifacts and removed completely prior to modeling. However, the effects of depression filling on river network structure and surface runoff were not clear. This study used 2D hydrodynamic modeling to evaluate these effects and found that removing depressions from DEMs is unnecessary and they should be taken into account in simulating drainage patterns and hydrologic response.

Summary: Dam construction and streamflow regulation have increasing impacts on impounded aquatic ecosystems worldwide. Hydropower dams, especially those causing hydropeaking phenomena, have various effects on downstream aquatic biota, particularly fish and their habitats. Technological advances in the past decades have allowed for the development of innovative methods and techniques involving technology to evaluate the impacts of hydropeaking on downstream ecosystems from a fish perspective. This paper provides a review of these methods, discussing their fundamentals, advantages, and disadvantages, and presents practical examples and results. The limitations of these methods and potential future technological advancements are also discussed.

Summary: The water-tourism nexus in the Mediterranean requires better knowledge, management, and governance to address environmental and societal challenges. This review analyzes the approaches used from 2000 to 2020, focusing on tourism's impact on water supply, determinants of water consumption, and water-saving mechanisms and technologies. The literature is found to be primarily water-centric and technical, lacking attention towards behavioral change and stakeholder action. Promising avenues for sustainable water use include transdisciplinary approaches and integrated tools such as hydrosocial cycle analysis, concept mapping, and agent-based modeling.

Summary: Individuals and communities socially construct risk, and societies with greater risk perception may be more apt to mobilize or adapt to emergent threats like climate change. Increasing climate change awareness is often considered necessary in the first stages of the adaptation process to manage its impacts and reduce overall vulnerability. This paper aims to identify the current research trends and set the future research agenda on climate change awareness, perceived impacts, and adaptive capacity from farmers' experiences and behavior.

Summary: Mapping river beds to identify water and sandbars is crucial but challenging. Conventional approaches are costly and inflexible, while remote sensing techniques provide a cost-effective solution. This study compared the capabilities of Sentinel-2 and Landsat 9 satellite imagery in mapping water bodies and found them to be consistent and complementary. However, the classification decision values of specific indices are important for accurate information extraction.

Summary: Urban areas are facing increasing extreme weather events, causing significant damage to infrastructure and human lives. Compact cities need to enhance their resilience, particularly in the sustainable design of urban public spaces. However, current public space designs often neglect the intersection of social and political issues. This study examines public space interventions in ten European compact cities over the past 25 years, and proposes an integrated approach. The results indicate progress in the social and environmental dimensions, but improvements are still required.

Summary: This article analyzes the behavior of the food system in the Barcelona Metropolitan Region during the early stage of the Covid-19 pandemic. Interviews were conducted with 11 entities and institutions in peri-urban areas to understand the socio-economic, environmental, and health aspects of food supply during the pandemic. The results highlight shortcomings in the metropolitan food system's operation and logistics, as well as the opportunities for collaboration between local producers and urban consumers. The study emphasizes the importance of peri-urban agricultural areas in ensuring food supply and land preservation, and the need for cooperation and mutual aid among stakeholders in the food system. Furthermore, the article calls for a rethinking of the agroeconomic model to strengthen the producer-consumer relationship and promote local food policies based on sustainability, sovereignty, and governance.
