“…However, this phenomenon consequently has some effects on hydrological dynamics [8,9]. The sustainability of water resources depends mainly on land use planning and management [8]. Some main West African basins, namely, Volta, Niger and Sassandra have already experienced these changes due to a rapid population growth rate and the transboundary condition of the basins.…”

West African basins play a vital role in the socio-economic development of the region. They are mostly trans-boundary and sources of different land use practices. This work attempts to assess the spatio-temporal land use and land cover changes over three South Western African basins (Volta, Mono and Sassandra basins) and their influence on discharge. The land use and land cover maps of each basin were developed for 1988, 2002 and 2016. The results show that all the studied basins present an increase in water bodies, built-up, agricultural land and a decline in vegetative areas. These increases in water bodies and land use are as a result of an increase in small reservoirs, of dugouts and of dam constructions. However, the decline in some vegetative clusters could be attributed to the demographic and socio-economic growth as expressed by the expansion of agriculture and urbanization. The basic statistical analysis of precipitation and discharge data reveals that the mean annual discharge varies much more than the total annual precipitation at the three basins. For instance, in the entire Volta basin, the annual precipitation coefficient of variation (CV) is 10% while the annual discharge CV of Nawuni, Saboba and Bui are 43.6%, 36.51% and 47.43%, respectively. In Mono basin, the annual precipitation CV is 11.5% while the Nangbeto and Athieme annual discharge CV are 37.15% and 46.60%, respectively. The annual precipitation CV in Sassandra basin is 7.64% while the annual discharge CV of Soubre and Dakpadou are 29.41% and 37%, respectively. The discharge varies at least three times much more than the precipitation in the studied basins. The same conclusion was found for all months except the driest months (December and January). We showed that this great variation in discharge is mainly due to land use and land cover changes. Beside the hydrological modification of the land use and land cover changes, the climate of the region as well as the water quality and availability and the hydropower generation may be impacted by these changes in land surfaces conditions. Therefore, these impacts should be further assessed to implement appropriate climate services and measures for a sustainable land use and water management.

“…For example, Guzha and Hardy (2010) applied the TOPNET model to predict watershed streamflow based on meteorological data. Garg et al (2017) used a three-soil-layer VIC (VIC-3L) hydrological model to study the impact of land-cover change on the hydrological regime. But none of these hydrological models is perfect, mainly because the model parameters have large uncertainties, which are caused by factors such as sparse data and uncertain human activities.…”

a school of environmental science and engineering, chang'an university, Xi 'an, china; b Key laboratory of subsurface Hydrology and ecological effects in arid region of the ministry of education, chang'an university, Xi'an, china ABSTRACT Water resources are the basis for the sustainable development of China. However, the country is currently facing alarming waterrelated problems associated with its fast economic development and climate change. This editorial introduces briefly the status of its water resources research at the national level and the researcher level. It also introduces the research reported in this thematic issue to highlight its role in addressing flood and water-scarcity issues, improving water management in inland plains and supporting the sustainable development of the country. Finally, some further recommendations for improving water resources research in China are offered.

“…In the last 50 years, ever since the launch of Landsat in 1970s, and IRS in 1990s, the efforts are made to include/integrate GST with traditional methods of WRM by, using RS based Land Use Land Cover (LULC) map, generation of soil map and Digital Elevation Model (DEM) for estimating runoff potential and soil erosion of an area (Garg et al, 2012), ground water potential mapping, soil erosion, sediment yield and reservoir sedimentation assessment (Lilhare et al, 2014, Rawat et al, 2017, Foteh et al, 2018Prasad et al, 2018), watershed delineation using DEM, economic and hydrologic evaluation of watershed management plans (Rao et al, 1994;Sharma and Thakur, 2007), flood and drought mapping, monitoring and damage assessment (Thakur and Sumangala, 2006; Corresponding author 2014, 2017), snow cover and glacier mapping and monitoring (Joughin et al, 2010;Kulkarni et al 2010;Bhambari and Bolch, 2011;Kumar et al, 2011;Thakur et al, 2012;Aggarwal et al, 2014;Nikam et al, 2017;Thakur et al, 2017a,b), irrigated area and irrigation infrastructure mapping and monitoring (Roy et al, 2010;Nikam and Aggarwal, 2012;NRSC, 2018), irrigation water and supply requirement (Durga Rao et al, 2001), assessment of land use land cover & climate change impact on water availability (Aggarwal et al, 2012;Aggarwal et al, 2016;Garg et al, 2017;Nikam et al, 2018). Most of these applications are driven by optical RS till mid-1990s, and addition of active Microwave (MW) remote sensing after mid-1990's and early 2000, with launch of ERS-1, 2 and Radarsat series of satellites (Britannica-2018, www.britannica.com/topic/list-of-satellites-2024625).…”

<p><strong>Abstract.</strong> In India, water resources are managed at different levels, i.e. at central level by Ministry of Water Resources, River Development &amp; Ganga Rejuvenation, Central Water Commission and Central Ground Water Board, at states level by state water resources departments, and at local level by Municipal Corporation and Panchayati Raj Institutions (PRIs). As per India’s national water policy of year 2012 focuses on adaption to climate change, enhancement of water availability, water demand management by efficient water use practices, management of floods and droughts, water supply and sanitation, trans-boundary rivers, conservation of water bodies and infrastructure, and finally research and training needs for each theme. Geospatial technology has unique role in all aforementioned themes. Therefore, research and training in use of Geospatial Technology (GST) in water sector is needed for each theme at different levels of water administration and water utilisation. The current paper discusses the existing framework and content of capacity building in water sector and geospatial technology in use at various government organizations and institutes. The major gap areas and future capacity building requirements are also highlighted, along with duration and timelines of training/capacity building programs. The use of distance learning/educations tools, social media, and e-learning are also highlighted in promoting use of GST in water sector. The emerging technological trends such as, new remote sensing sensors for measuring water cycle components, ground sensors based field instruments, cloud based data integration and computational models, webGIS based water information portals and training needs of new technologies are also emphasised.</p>
