For decades, increasing land productivity was a major driver of improving food security and reducing rural poverty. However, with increasing water scarcities, competing water demand across different sectors, and increasing cost of investments in water resources development require a paradigm shift. Improving the productivity of water use is emerging as a new way of addressing water scarcity while reducing vulnerability and improving income. Increasing both physical and economic water productivities (quantity per drop and value per drop) are central to this approach. The extent to which physical and economic water productivity should be improved is and area and context specific. However, the approach is especially important in areas that are populated with large agriculturally dependent small-holder rural people and areas that experience recurrent droughts and floods and lack access to proper infrastructure. A major part of the Ganga-Brahamaputra-Meghna (MBG) river basins have such characteristics. This report examines the current situation of poverty, food security and water productivity and their linkages and knowledge gaps in the MBG basins.

Climate extremes such as droughts and intense rainfall events are expected to strongly influence global/regional water resources in addition to the growing demands for freshwater. This study examines the impacts of precipitation extremes and human water usage on total water storage (TWS) over the Ganges-Brahmaputra-Meghna (GBM) River Basin in South Asia. Monthly TWS changes derived from the Gravity Recovery And Climate Experiment (GRACE) (2002–2014) and soil moisture from three reanalyses (1979–2014) are used to estimate new extreme indices. These indices are applied in conjunction with standardized precipitation indices (SPI) to explore the impacts of precipitation extremes on TWS in the region. The results indicate that although long-term precipitation do not indicate any significant trends over the two subbasins (Ganges and Brahmaputra-Meghna), there is significant decline in rainfall (9.0 6 4.0 mm/decade) over the Brahmaputra-Meghna River Basin from 1998 to 2014. Both river basins exhibit a rapid decline of TWS from 2002 to 2014 (Ganges: 12.2 6 3.4 km3 /yr and Brahmaputra-Meghna: 9.1 6 2.7 km3 /yr). While the Ganges River Basin has been regaining TWS (5.4 6 2.2 km3 /yr) from 2010 onward, the Brahmaputra Meghna River Basin exhibits a further decline (13.0 6 3.2 km3 /yr) in TWS from 2011 onward. The impact of human water consumption on TWS appears to be considerably higher in Ganges compared to Brahmaputra-Meghna, where it is mainly concentrated over Bangladesh. The interannual water storage dynamics are found to be strongly associated with meteorological forcing data such as precipitation. In particular, extreme drought conditions, such as those of 2006 and 2009, had profound negative impacts on the TWS, where groundwater resources are already being unsustainably exploited.

This article investigates the motives and incentives that drive countries’ diplomatic efforts in water disputes. It aims to identify links between the formation of water management institutions (WMIs) and the outcomes of such institutional cooperation. Three features have been identified as key to the effectiveness of WMIs: (1) the development of trust; (2) sanctions aimed at curbing cheating; and (3) the balancing of different countries’ interests over shared waters. This article conducts a comparative analysis of the formation of institutional arrangements among three riparian states by focusing on two cases: water interactions between China and India, and between India and Bangladesh. It argues that India, China and Bangladesh have exhibited different preferences in regard to their participation in WMIs. The two cases illustrate how different WMIs are formed and also how, in proportion to variations in the level of competition over water quantity, diplomatic cooperation through environmental agreements can lead to different outcomes with varying degrees of success. This article concludes that in the context of the global South, where foreign relations are unstable and countries’ reliance on river basins varied, building trust and balancing interests over water management are especially important to the formation of effective institutional arrangements.

This article examines the power interplay that shapes the transboundary water interaction in the Brahmaputra River basin. The article provides two key insights based on data sharing and bilateralism aspects. First, the lack of a standard, hydrological data-sharing mechanism has created a sense of mistrust between riparians. Second, bilateralism and power asymmetry between the riparian countries has created a sense of unilateral control over the Brahmaputra River. This article concludes that due to regional geo-politics, issues of sovereignty, and unequal power, negotiation for a multilateral basin-wide treaty at this moment is a non-starter in the Brahmaputra basin.

This article analyzes key factors affecting transboundary water cooperation in the Brahmaputra River basin at multiple scales. The analysis of multi-track diplomacy reaffirms the potential of actor-inclusive approaches, arguing for a need to go beyond purely focusing on formal legal norms and consider the possibilities of cultural norms of informal processes of cooperation. Various ‘windows of opportunity’ exist in the current phase of the Brahmaputra basin’s development, leading to exploration of a Zone of Possible Effective Cooperation, arising from the effort to scale up multi-track initiatives as well as broader geo-political-economic changes happening across and beyond the basin.

Countries sharing the Brahmaputra River have for decades deliberated on formulating and implementing cooperative strategies to develop the potential of the basin. Yet, little progress has been made so far at the government-to-government track 1 level in achieving regional cooperation due to the diverse national interests of the riparian countries. This has led to tension and friction among co-riparian nations and mistrust at political level. Drawing from the Brahmaputra Dialogue, this paper aims to highlight the merit of multi-track and multilateral dialogue processes for building trust and confidence between the riparian countries – paving a way towards transboundary cooperation. The paper concludes that given the geo-politics and the national interests of each riparian nation, negotiation for a treaty for cooperation through track 1 diplomacy, in the Brahmaputra River Basin (BRB), is a non-starter. Multi-track and multilateral dialogues can provide a platform to pursue positive interactions and can be viewed as an extension to existing state-diplomacy in BRB, to bring about sustainable change in the basin management.

Accurate (spatio-temporal) estimation of the crop yield relation to climate variables is essential in the densely populated Indus, Ganges, and Brahmaputra (IGB) river basins of South Asia for devising appropriate adaptation strategies to ensure regional food and water security. This study examines wheat (Triticum aestivum) and rice (Oryza sativa) crop yields’ sensitivity to primary climate variables (i.e., temperature and precipitation) and related changes in irrigation water demand at different spatial (i.e., province/state, districts and grid cell) and temporal (i.e., seasonal and crop growth phase) scales. To estimate the climate driven variations in crop yields, observed and modelled data applying the Lund-Potsdam-Jena managed Land (LPJmL) model are used for six selected study sites in the IGB river basins over the period 1981–2010. Our statistical analysis underscores the importance of impacts assessments at higher spatio-temporal scales. Our grid cell (aggregated over study sites) scale analysis shows that 27–72% variations in wheat and 17–55% in rice crop yields are linked with temperature variations at a significance level of p < 0.001. In the absence of irrigation application, up to 39% variations in wheat and up to 75% variations in rice crop yields are associated with precipitation changes in all study sites. Whereas, observed crop yields show weak correlations with temperature at a coarser resolution, i.e., up to 4% at province and up to 31% at district scales. Crop yields also showed stronger sensitivity to climate variables at higher temporal scale (i.e., vegetative and reproductive phases) having statistically strong negative relationship with temperature and positive with precipitation during the reproductive phase. Similarly, crop phase-specific variations in climate variables have considerable impacts (i.e., quantity and timing) on irrigation water demand. For improved crop water planning, we suggest integrated climate impact assessments at higher spatio-temporal scales which can help to devise appropriate adaptation strategies for sustaining future food demand.

Groundwater plays a major role in human adaptation and ecological sustainability against climate variability by providing global water and food security. In the Indus-Ganges-Brahmaputra-Meghna aquifers (IGBM), groundwater abstraction has been reported to be one of the primary contributors to groundwater storage variability. However, there is still a lack of understanding on the relative influence of climate and abstraction on groundwater. Data-guided statistical studies are reported to be crucial in understanding the human-natural complex system. Here, we attributed the long-term (1985–2015) impact of local-precipitation, global-climate cycles, and human influence on multi-depth groundwater levels (n=6753) in the IGBM using lag correlation analysis, wavelet coherence analysis, and regression-based dominance analysis. Our findings highlight the variable patterns of phase lags observed between multi-depth groundwater levels and precipitation depending on the different nature of climatic and anthropogenic drivers in different parts of the basin. We observed intuitive responses, i.e., rapid response in shallow groundwater and relatively delayed responses to the global climate patterns with increasing depth. However, in the most exploited areas, the hydrological processes governing the groundwater recharge are overwhelmed by unsustainable groundwater abstraction, thus decoupling the hydro-climatic continuum. Our results also suggest groundwater abstraction to be the dominant influence in most of the basin, particularly at the greater depth of the aquifer, thus highlighting the importance of understanding multi-depth groundwater dynamics for future groundwater management and policy interventions.

Irrigated agriculture in South Asia depends on meltwater, monsoon rains and groundwater. Climate change alters the hydrology and causes shifts in the timing, composition and magnitude of these sources of water supply. Simultaneously, socio-economic growth increases water demand. Here we use a high-resolution cryosphere–hydrology–crop model forced with an ensemble of climate and socio-economic projections to assess how the sources of irrigation water supply may shift during the twenty-first century. We find increases in the importance of meltwater and groundwater for irrigated agriculture. An earlier melt peak increases meltwater withdrawal at the onset of the cropping season in May and June in the Indus, whereas increasing peak irrigation water demand during July and August aggravates non-renewable groundwater pumping in the Indus and Ganges despite runoff increases. Increasing inter-annual variability in rainfall runoff increases the need for meltwater and groundwater to complement rainfall runoff during future dry years.

Study region: The Brahmaputra River Basin.
Study focus: The Brahmaputra River Basin (BRB) is the most environmentally fragile and politically unstable transboundary river basin in South Asia. Therefore, incorporating the environmental sector into water-energy-food system analysis is necessary to better serve water resource management in the BRB. Integrated water resources system analysis can provide more perspectives for alleviating political tension and promoting cooperation in the basin. This study proposes a modeling framework to explore the water-energy-food-environment (WEFE) nexus and analyze transboundary cooperation opportunities in the BRB. Employing the framework, we attempt to answer three questions: (1) how can we understand the relationships between various sectors and coordinate their water demands? (2) How do these relationships influence riparian countries’ decisions? (3) What measures can promote the sustainable development of the BRB under climate change and water infrastructure development?
New hydrological insights for the region: The results show that the trade-off curve between economic benefits and environmental costs has declining marginal value in the BRB. When environmental constraints are raised, countries are more inclined to cooperate to obtain more economic benefits. Full cooperation in the BRB increases the economic benefits and prompts riparian countries to take a greener road among the shared socioeconomic pathways (SSP126). Water resource project construction can improve the utility of water resources in a country, thus enhancing its discourse power on benefit reallocation.
