Small town water services sustainability checks: development and application in Ethiopia
With rising coverage figures and the advent of the Sustainable Development Goals, there is increasing attention given to assessing and monitoring the sustainability of water services. Previous efforts in the rural water supply sector have included the development of sustainability checks, while in the urban water supply sector, benchmarking of water services and the performance of utilities has become common practice. This paper argues that neither rural sustainability checks, nor urban benchmarking frameworks,...
How to handle key sustainability issues of products and ingredients in the cosmetics industry

Multi-objective optimization for sustainable groundwater management by developing of coupled ...
This study addresses the issue of optimal management of aquifers using a mathematical simulation- optimization model which relies on the stability of water quality and quantity, considering salinity. In this research first we developed a hydrological model (SWAT) to estimate recharge rates and its spatiotemporal distribution. Then, groundwater simulation of the basin was simulated and calibrated using MODFLOW 2000 and water quality was simulated and calibrated using MT3DMS. Afterwards, a multi-objective optimizatio...
Assessing the influence of social capital on water point sustainability in rural Ethiopia
Despite considerable investment, sustainability of rural water resources remains a critical challenge in Ethiopia. Evidence suggests social capital – the networks, norms, and trust that facilitate cooperative behaviors – influences a community's ability to manage communal water resources. In turn, strong community governance of water resources may lead to sustainable resource management. Existing evidence provides a framework for exploring the relationship between social capital and governance of common-pool...
