Abstract:
... Over the past two decades, strategies for sustainable development and water environment governance have become the main ways to improve regional water-use efficiency. However, the evolutionary characteristics and drivers of the regional water-use efficiency remain unclear, and the effectiveness of national strategic instruments must still be evaluated. The study uses the minimum distance to the st ...

Abstract:
... Establishing a holistic approach to manage floods and droughts is essential considering the different hydrological conditions. This work aimed to demonstrate how the integrated management of floods and droughts (IMFD) can increase sustainability and decrease the vulnerability of reservoirs against water-related disasters. To do so, a non-integrated management of floods and droughts (NMFD) is compa ...

Abstract:
... The demand for freshwater resources has increased in recent times and has been exacerbated by escalating global population and increasing drought indices in the world’s agricultural zones. Irrigated agriculture is inevitably a wasteful water user that has deprived other sectors of the scarce resource. Improving water use efficiency in irrigated agriculture is therefore crucial for sustainable agri ...

Abstract:
... This study explores recent changes in evaporative demand and water availability across 100 river sub-basins in India by partitioning the actual evapotranspiration (AET) into green water evapotranspiration (ET-Green) and blue water evapotranspiration (ET-Blue). For computation of ET-Green and ET-Blue, the Budyko framework is applied to long-term scenario (2003–2017) and to intra-annual averaged ser ...

Abstract:
... Stomatal pores facilitate gaseous exchange between the inner air spaces of the leaf and the atmosphere. The pores open to enable CO₂ entry for photosynthesis and close to reduce transpirational water loss. How stomata respond to the environment has long attracted interest in modeling as a tool to understand the consequences for the plant and for the ecosystem. Models that focus on stomatal conduct ...

The study presents the morpho-physiological performance under induced drought condition and molecular marker based genetic variability amongst 13 rice varieties released for cultivation in Uttar Pradesh, India. An attempt was made to identify suitable genotypes for drought affected areas, based on their morpho-physiological characteristics and genetic diversity. The physiological parameters of pho ...

Abstract:
... The security of water resources is of great importance to long-term sustainability. In order to better ensure the security of water resources, a significant link is to conduct water resources security evaluation, which should be considered from many perspectives as it involves natural reserves, social production, the efficiency of use, and environmental protection. In this paper, a fuzzy analytic ...

Abstract:
... Water scarcity is a major problem in the arid climate of Iraq’s Western Desert and people struggle to manage the precarious water supply. Harvesting rainwater is one sustainable method that can be used to increase the supply of water. Rainwater harvesting systems (RWH) are considered to be sustainable “if they can continue collecting, utilising, and consuming natural water resources for maximum li ...

Abstract:
... Nowadays, pressurized irrigation systems have been developing in farms to increase water use efficiency that are successful when the inflow is accurately supplied from water sources. In large irrigation networks, water conveyance and distribution systems are mainly open channels facing several uncertainties. Therefore, water delivery to farms is of the most important tasks that should be done accu ...

Abstract:
... The non-degradability of most plastic packaging materials and the deficiency in recycling infrastructure on a global scale causes huge environmental problems. To address this problem, packaging materials produced from natural macroalgae polymers are a very promising alternative. The cultivation potential for macroalgae is huge and they are not in competition to food crops. Although the basic idea ...

Abstract:
... Carbon dioxide concentration is likely to increase by 2–2.5 fold by the end of 21ˢᵗ century from its current level of 400 ppm due to anthropogenic activities mediated climate change. As yam is an important food and nutrition security crop, it is of paramount importance to assess the effect of climate change on the physiological processes especially photosynthetic efficiency to identify the climate ...

Abstract:
... Intrinsic water-use efficiency (iWUE) is a key physiological trait; however, the spatiotemporal variation in iWUE and which factors affect iWUE in the tropics and subtropics are poorly known. We determined the temporal (1920-2010) and spatial patterns of iWUE using leaf carbon-isotopic composition (δ¹³C) of 1,811 herbarium specimens and associated these patterns with environmental factors across b ...

Abstract:
... Water footprints and virtual water are widely used as essential tools for water use and conservation analysis of basins worldwide. Despite the importance of water-rich basins as the main force for water-saving, water use analysis has been mainly for water-scarce basins rather than water-rich basins in the existing literature. To fill the gap, in this paper, we investigate the water footprint and v ...
