- Impaired Water Hazard Zones: Mapping Intersecting Environmental Health . . .
This study advanced a rigorous spatial analysis of surface water-related environmental health vulnerabilities in the California Bay-Delta region, USA, from 2000 to 2006 It constructed a novel hazard indicator—“impaired water hazard zones’’—from regulatory estimates of extensive non-point-source (NPS) and point-source surface water pollution, per section 303(d) of the U S Clean
- Soil Salinity: Effect on Vegetable Crop Growth. Management . . . - MDPI
Salinity is a major problem affecting crop production all over the world: 20% of cultivated land in the world, and 33% of irrigated land, are salt-affected and degraded This process can be accentuated by climate change, excessive use of groundwater (mainly if close to the sea), increasing use of low-quality water in irrigation, and massive introduction of irrigation associated with intensive
- Nitrate Uptake by Cellulose-Based Anion Exchange Polymers . . . - MDPI
Nitrate contamination of ground water is a serious problem due to the intensive agricultural activities needed to feed the world’s growing population While effective, drinking water treatment using commercial ion exchange polymers is often too expensive to be employed At the same time, lignocellulosic waste from crop production—an abundant source of the renewable polymer cellulose—is
- A Review of the Water Desalination Technologies - MDPI
Desalination is commonly adopted nowadays to overcome the freshwater scarcity in some areas of the world if brackish water or salt water is available Different kinds of technologies have been proposed in the last century In this paper, the state of the mainstream solutions is reported, showing the current commercial technologies like reverse osmosis (RO), Multi-Stages Flash desalination (MSF
- Water Security Under Climate Change: Challenges and Solutions . . . - MDPI
Different countries face significant challenges in managing water-related natural hazards, such as floods and shortages, while ensuring adequate water quality and quantity to satisfy human needs and preserve ecosystems Climate change projections exacerbate this situation by intensifying the hydrological cycle, resulting in substantial changes in precipitation patterns, evapotranspiration, and
- An Overview of Smart Irrigation Management for Improving Water . . .
Global drylands, covering about 41% of Earth’s surface and inhabited by 38% of the world’s population, are facing the stark challenges of water scarcity, low water productivity, and food insecurity This paper highlights the major constraints to agricultural productivity, traditional irrigation scheduling methods, and associated challenges, efforts, and progress to enhance water use
- Remote Sensing Techniques for Water Quality Monitoring: A Review - MDPI
Freshwater resources are facing increasing challenges to water quality, due to factors such as population growth, human activities, climate change, and various human-made pressures While on-site methods, as specified in the USGS water quality sampling handbook, are usually precise, they require more time, are costly, and provide data at specific points, which lacks the essential comprehensive
