“…The Water Evaluation and Planning system (WEAP) developed by the Stockholm Environment Institute (Sieber and Purkey 2011) has been widely used worldwide in many regional water allocation problems, e.g. (Dau et al 2020;Dau et al 2018;Kou et al 2018;Momblanch et al 2019). The model aims at supporting integrated water resources planning and management by representing the water allocations between agricultural, municipal and environment uses, which usually requires a full integration of supply, demand, water quality, and ecological considerations.…”

Climate change in the Indian Himalayan region is being manifested in loss of glaciers and altered patterns of monsoon rainfall. Simultaneously, rapid population growth together with economic development are increasing sectoral water demands and changing land use patterns.This study investigated the impact of this complex interplay on water resources in the Beas-Sutlej water resources system. The GFDL-CM3 model was used to describe RCP8.5 future meteorological conditions throughout the 21 st century. Population and land use changes were projected under the Shared Socioeconomic Pathway-1 (SSP1). The Water Evaluation And Planning (WEAP) system was applied for assessing sectoral water demands. The results showed increasing runoff during the pre-monsoon and monsoon seasons, due respectively to increased glaciers melting and more rainfall. It also emerged that irrigation water demand will decrease moderately in Punjab (8 -13%) and Haryana (1 -9%); however, the situation was reversed in Rajasthan where it increased by 14%. Adaptation strategies were proposed including increased water allocation to Rajasthan and converting lands to cultivating more staple crops in Punjab and Haryana.

“…In this study, a reservoir operation simulation program in WEAP (Water Evaluation And Planning) model, which was developed by the Stockholm Environment Institute (Sieber and Purkey, 2011) and has been widely used in many regional water allocation problems (Dau et al, 2021a, Dau et al, 2018, was applied for determining optimal water allocation for each monthly time step based on demand priorities and supply preference. The optimal rule curves were developed based on Genetic Algorithm (GA), for a multiple purpose and combined within a single objective function (Eq.…”

“…Goyal and Surampalli (2018) stated that current 1.2 billion Indian population have experienced tremendous economic growth in the last 20 years with only 4% and 9% of the world's water resources and arable land, respectively. Such a phenomenal growth of the population can only lead to higher domestic, industrial and agricultural water demands (Dau et al, 2021a).…”

The shifts in socio-economic development and climate conditions currently become the challenge for water resources system security in the Himalayan region. The aforesaid concern was found pertinent to the main objective of this study, which is to evaluate the combined impacts of climate and socioeconomic changes on likely future water security in the Himalayan basin, India. The future climate was projected by Multi-model Ensembles under the Representative Concentration Pathway (RCP) 4.5 scenario. Land use projection under the Shared Socioeconomic Pathway (SSP) 1 scenario was performed using Markov Chain, whose transition probabilities were derived using multi-layer perceptron neural networks. The results showed that future annual precipitation and temperature at the downstream part will increase from baseline by 5% -10% and 1.0 o C -1.55 o C, respectively. The land use projections showed that irrigated areas will decrease for Punjab by 10% -30% and Haryana by 5% -10% due to the increase in urbanisation, whereas it will be increased in Rajasthan by 12% -18%. Consequently, the annual irrigation water demand was found to be decreased by 10% for Punjab and 5% for Haryana, while it will be increased by 13% for Rajasthan. Eventually, the obtained findings will be beneficial for planning strategies to ensure water security in the Himalayan region, in particular the Beas-Sutlej basin.

“…Various studies have been carried out at the basin scale on the impact of climate change on water resources, especially evaluating the reduction of rainfall and flows (Amraoui et al 2019;Mehrazar et al 2020;Dau et al 2021;Maurya et al 2023), extreme events (Suárez-Almiñana et al 2020;Tegegne and Melesse 2020) or sea level rise and its effects in coastal wetlands (Estrela-Segrelles et al 2021). This research stands out for studying the effect of climate change on the ecological status of water bodies at country level, something that had not been evaluated up to now.…”

The Mediterranean is one of the most vulnerable regions to climate change impacts. Climate change scenarios predict that water temperature will increase up to 2.2–2.9ºC by the end of the century in Mediterranean rivers. This will cause an impact on water quality (oxygen dissolved reduction), reduce the available habitat of cold-water fish species and affect macroinvertebrates. Risk assessment methodology develops indicators that integrate hazard, exposure and vulnerability. Risk maps are key tools to prioritize the areas in which adaptation measures should be implemented in order to improve the adaptive capacity of ecosystems. The risk of habitat loss and ecosystem damage is very high in Mediterranean rivers. For RCP8.5, the 80% of the waterbodies that currently have brown trout presence are in High Risk (HR) or Very High Risk (VHR) of disappearing in the long term future (2070–2100) and the 35% in the short term (2010–2040). It will affect the middle sections first and the headwaters of the rivers later. The 92% of the waterbodies are in HR-VHR of macroinvertebrate family’s affection (2070–2100) and dissolved oxygen may be reduced by 0.5–0.75 mgO2/l (2070–2100). The restoration of the riverside vegetation is the main adaptation measure. This reduces significantly the stream temperature. Other measures are the groundwater protection and cold-water discharge from the reservoirs.
