“…A few studies have been conducted on the assorted blueprint of groundwater storage, disparity depletion and shortage in India mainly using satellite data [21,22,43,51]. However, using the current RS data by employing the MCDM method at the block or district level, especially on Murshidabad district, considering the significant neighborhood criteria to inspect GWS dynamics covering pre-and post-monsoon seasons over a long episode of 20 years (2000-2020), was our unsullied and remarkable endeavor.…”

“…The study revealed that by 2050, the anticipated food production in India will be 250 million metric tons, which necessitates a sharp demand for water. Apart from this, the changes in the impending terrestrial water, the increasing rate of urbanization and their confrontation with water assets has led to groundwater depletion heterogeneously [20][21][22][23], and sustainable setting up and appropriate supervision of the groundwater must be encouraged to tackle the swelling demand for water for cost-effective advancement.…”

The present study intended to assess groundwater storage dynamics (GWS) and identify potential zones using the Multi-Criteria Decision Making (MCDM) method and geospatial technology in the Murshidabad district of West Bengal, India. The study district is located in the Ganga–Padma–Bhagirathi rivers’ floodplain and covers approximately a 5324 km2 area, comprising 26 blocks in five sub-divisions. The study portrayed a quantitative investigation of the pre-monsoon and post-monsoon season’s variability of GWS from 2000 to 2020, taking Landsat TM/Landsat 8 OLI/SRTM satellite data. The geo-spatio-temporal analysis of groundwater storage variability for 20 years was carried out by such remotely sensed data with the geospatial method to portray the dynamics and uncover the potential zones of GWS using various cartographic and statistical techniques. We determined nine parameters for the study, and the analytical hierarchy process (AHP) method was employed for the computation. The present estimation and assessment include the MCDM method, covering assorted parameters and the variations and aspects of GWS in the pre- and post-monsoon seasons from 2000 to 2020. The outcome illustrates that a decline in water storage has taken place in most of the blocks of Murshidabad district on average during the study period, which indicates a water stress provison in the near future. However, the micro (block)-level scenario of the spatiotemporal dynamics of GWS and the potential zonation in the Murshidabad District were investigated to form a location-specific micro-level arrangement for the sustainable management of water.

“…Nesse aspecto é notado o crescente número de estudos realizados na busca do entendimento dos efeitos referentes às mudanças nas características de cobertura do solo nos processos hidrológicos. A preocupação sobre esse assunto é observada em todo o mundo através de pesquisas desenvolvidas no campo das mudanças climáticas provenientes das alterações nos usos do solo e os efeitos na disponibilidade de água (Siqueira et al, 2021), pelos efeitos da urbanização nos recursos hídricos (Prasood et al, 2021), pelos efeitos decorrentes dos processos de desmatamento e aumentos das áreas de agricultura e pastagens nos regimes hídricos das bacias hidrográficas (Adegboyega, 2021) (Wang et al, 2021) e até mesmo na relação de disponibilidade de água para a geração de energia hidrelétrica (Mello et al, 2021) (Zhao et al, 2021).…”

Tem se tornado comum encontrar trabalhos preocupados em demonstrar os efeitos das expansões urbanas no microclima regional e as alterações dos regimes hídricos nessas áreas, assim como os efeitos dos centros urbanos na qualidade da água e os prejuízos à segurança hídrica relacionado a questões de saúde pública (Alavijeh et al, 2021) (Prasood et al, 2021).…”

O aumento da demanda por água tem agravado os conflitos entre diferentes usuários e cerca de metade da população mundial vive em áreas de potencial escassez hídrica, por pelo menos um mês ao ano, percentual esse que pode se agravar até 2050. Estas duas evidências apontam a dimensão da crise hídrica em uma escala mundial. A ampla literatura sobre o tema destaca que essa crise, está mais relacionada à gestão do que à disponibilidade do recurso. Nesse sentido, existem lacunas em relação ao entendimento e aplicabilidade de instrumentos responsáveis pelo suporte ao processo de Gestão Integrada de Recursos Hídricos - GIRH, assim como, sua importância para a Segurança Hídrica. Neste contexto, o objetivo principal da pesquisa é caracterizar o cenário atual de Segurança Hídrica em uma bacia hidrográfica interestadual, assim como as fragilidades dos instrumentos legais envolvidos nesse processo. Para tanto, foi elaborado um mapeamento de risco demonstrando os pontos de fragilidade à Segurança Hídrica a partir dos dados de consumo da água, uso e ocupação do solo e disponibilidade hídrica da bacia. O estudo foi realizado na bacia hidrográfica do rio Paranaíba, devida sua importância socioeconômica para a região centro oeste do Brasil e apresenta como principais conclusões a necessidade da efetiva aplicação dos instrumentos de gestão da Lei nº 9.433 de 1997, além da demonstração dos riscos elevados à segurança hídrica em regiões à montante de grandes centros urbanos e principalmente em regiões próximas à nascente do rio Paranaíba. Os resultados encontrados refletem uma realidade nacional.Palavras-chave: Segurança hídrica, Instrumentos de gestão da água, Risco hídrico, Usos do solo. Challenges in the Process of Obtaining Water Security Front of Water Management Instruments Application A B S T R A C TThe increase in water demand has aggravated conflicts between different users and about half of the world population lives in areas of potential water scarcity, for at least one month a year, a percentage that could worsen until 2050. These two pieces of evidence point to dimension of the water crisis on a world scale. The extensive literature on the subject highlights that this crisis is more related to management than to resource availability. In this sense, there are gaps in the understanding and applicability of instruments responsible for supporting the Integrated Water Resources Management - IWRM process, as well as their importance for Water Security. In this context, the main objective of the research is to characterize the current scenario of Water Security in an interstate watershed, as well as the weaknesses of the legal instruments involved in this process. To this end, a risk mapping was drawn up showing the weak points in terms of water security, based on data on water consumption, land use and occupation, and water availability in the basin. The study was carried out in the hydrographic basin of the Paranaíba River, due to its socioeconomic importance for the central west region of Brazil, and presents as its main conclusions the need for the effective application of the management instruments of Law nº. 9,433 of 1997, in addition to the demonstration of the high risks to water security in upstream regions of large urban centers and especially in regions close to the source of the Paranaíba river. The results found reflect a national reality.Keywords: Water security, Water management instruments, Water risk, Land use.

“…UNEP (2016) reported that human health and productive activities are severely stressed as a result of point and non-point farm discharge carrying large quantities of agrochemical residues, forever chemicals, organic matter, drug residues, sediments, and saline drainage into water bodies, i.e., into the aquatic ecosystems. Furthermore, the steep rise in water demand/use by citizens is one of the major issues driving water scarcity in many countries, including India ( Prasood et al, 2021 ). Table 1.…”
