“…According to the Bangladesh Water Development Board (BWDB), the groundwater existed beneath 2 to 14 meters of sediment during the pre-monsoon period. While in the dry season, it was found between 4 and 12 meters in the North-Eastern part of Bangladesh (Kutub, 2015). The larger values mostly represent the depletion in urban areas.…”

Groundwater is the major source of water to meet up the vast domestic and agricultural demand in Bangladesh. Additionally, reduction in reliable surface water resources resulting the increased reliance on groundwater day by day. Therefore, monitoring the groundwater fluctuation over time is crucial to ensure the sustainable use of groundwater resources in future. The present study analyzed historical groundwater data to know the behaviour of groundwater at four locations of two districts Pabna and Rangpur in the North-Eastern part of the country. Historical groundwater level data and monthly rainfall data from 1989 to 2017 were collected from Bangladesh Water Development Board and Bangladesh Meteorological Department, respectively. The annual maximum groundwater table depth (MaxGWT) and minimum groundwater table depth (MinGWT) and its trend was analyzed, and positive and negative recharge years were identified from these values. We found the maximum declining rate at 6.6 cm annually and the maximum 205 cm total depletion in the study area. The number of years of negative recharge is more than that of positive recharge for 32 years. As a result, a declining trend in groundwater table was found at three locations of the study area. The maximum groundwater table remains below suction limit at Ishwardi, causes no shallow tubewell (STW) works during that period. A declining trend in annual rainfall is observed in Pabna district. A linear relationship between rainfall and recharge was found at two locations of the study area. Bangladesh Rice J. 25 (2) : 85-95, 2021

“…In Bangladesh, groundwater depth and groundwater-level deficit (drought) has been reported to be continuously increasing [100], and the decline has been linked with urbanization; as a result groundwater extraction in many locations has become unsustainable with predicted catastrophic events such as earthquakes, subsidence, and pollution being highly possible [101]. Due to current challenges related to stream low flows experienced in several countries, recommendations have been made on complementary management for high flows that occur early in the growing season with maintenance of adequate base flows to maintain ecosystem functioning in the face of hydrologic alterations induced by climate change and human water demand [102].…”

Water resource protection is central to sustainable water supply management for human wellbeing and for the ecological ecosystem to flourish. This review paper focuses on highlighting the role of groundwater and surface water protection practice to improve their sustainable utilization in South Africa. Using an integrative approach, this paper initially reflects on the history of water resources utilization, and it examines what is understood by the term “water resources protection”. This review paper then continues by providing an analysis of the current practice at global and local levels. The study found evidence of water resource utilization in the ancient times with limited challenges despite unavailability of regulation mechanisms. However, in recent times water resource availability challenges linked to water availability and water quality deterioration are evident globally despite having policies and regulation in place. Based on the findings of the study, a novel conceptual results-oriented policy monitoring framework is proposed, and it was distinctively designed to address challenges identified in practice in the South African context. The framework is configured on (1) the vision of the catchment protection and sustainable use, (2) water resources protection practices, (3) the state of water resources, and (4) policy evaluation and review processes as the key elements to drive success in policy implementation and monitoring practice. Therefore, this paper provides a foundation for results-oriented policy monitoring for water resources protection to improve sustainable water resources utilization in the country. The proposed framework can be considered as a reference guide that can be used to monitor policy practice for water resources protection by following a result-oriented monitoring approach

“…Sumaiya & Khatun (2016) examine groundwater variability as it relates to precipitation variability. Kutub (2015) focused on groundwater weariness circumstances, but didn't concentrate on controlling factors. As such, more investigations are required for a more signi cant appreciation of groundwater levels and different controlling components.…”

Water insufficiency during the pre-monsoon season and rapidly falling underground freshwater levels is a common scenario in the towns and cities of Bangladesh. The objective of the study is to investigate the spatiotemporal depletion of groundwater levels (GWL) in a drought-prone Rangpur district, northern region of Bangladesh. Groundwater observation well data from 1980 to 2019 was used for this purpose. Rainfall, temperature, irrigation, and land use/land cover datasets are used to assess the factors influencing groundwater level depletion. Linear regression, and the least square regression model were used to identify the trend of GWL depletion. Results show that GWL in drought-prone regions is declining rapidly because of the excessive withdrawal of groundwater and land-based reservoirs for irrigation and household needs. The declining GWL is alarming during the pre-monsoon and post-monsoon seasons due to some disproportional mismanagement in the study area. Among the rates of decline, the trend in maximum depth has a comparatively higher rate than the others. Findings from the study show that severe withdrawal of groundwater in agriculture, a decreasing amount of annual rainfall, and degradation of climatic factors in the area are all attributed to a lowering trend in groundwater level.
