The Sustainable Development Goals (SDGs) are offered as a comprehensive strategy to guide and encourage sustainable development at multiple scales both nationally internationally. Furthermore, through the of indicators associated with each goal sub-goal, SDGs support notion monitoring, evaluation adaptive management, underpinned by aspirations social justice, equity transparency. As such, ethical intention is well founded. However, possible conflicts trade-offs between individual have received little attention. For example, relating poverty (SDG 1), inequality 10), food security (SDG2), economic 8) life in water on land (SDGs 14 15), potentially competing many circumstances. In social–ecological context, policy formulation increasingly adopting systems approaches, which analyse complex interactions system elements. Adopting such an approach this work, above analysed for coastal Bangladesh. This demonstrates potential SDGs, including agricultural farming approaches light reduction, growth environmental integrity equity. To develop coherent relevant socio-ecological strategies, appropriate decision frameworks need be co-developed across range stakeholders decision-makers. Integrated models great process.

Abstract Snow and glacier melting accumulation are important processes of the hydrological cycle in cryosphere, e.g., high‐mountain areas. Glaciers snow cover respond to climate change notably over Tibetan Plateau (TP) as Earth's Third Pole where complex topography lack ground‐based observations result knowledge gaps large uncertainties model output. This study develops a melt for distributed (Coupled Routing Excess Storage model, CREST) using Upper Brahmaputra River (UBR) basin TP case study.

A progressive two‐stage calibration strategy is developed derive parameters, i.e., (1) (stage I) (2) runoff generation routing multisource data II). Stage‐I performed MODIS area (SCA) product blending water equivalent (SWE) combined with partial situ measurements.

Abstract Satellite remote sensing combined with water balance calculations provides a promising approach to estimating evapotranspiration (ET), critical variable in water‐energy exchange. Here we compare ET estimates from terrestrial and atmospheric balances, multisource (AVHRR, GLEAM, MOD16), land surface model (GLDAS NOAH) for headwaters on the Tibetan Plateau (TP), that is, of Brahmaputra (HBR), Salween (HSR), Mekong (HMR), Yangtze (HYR), Huang (Yellow; HHR) Rivers, 2003–2012 period. Results show (1) estimated balances agrees closely three basins (HMR, HYR, but has large discrepancies other two (HBR HSR), mainly caused by uncertainties balance; (2) agreement between various products balance‐derived baselines is highest GLEAM (HMR HYR) GLDAS NOAH another (HSR HHR); (3) all are found most glacierized HBR, which may reflect importance sublimation process. The decadal mean based HHR (447 mm/year) HSR (430 lowest HBR (238 mm/year), ranging 51% 78% precipitation five TP headwaters. These findings have important implications estimation headwaters, greatly influences downstream availability.
