Balancing economic growth and river protection is a significant undertaking, but not an impossible one. This policy paper addresses the environmental, social, and regulatory complexities surrounding industrial production in Bangladesh. It examines how power dynamics in global supply chains influence state-market regulatory relationships and provides recommendations to strengthen state regulatory capacity, enhance civil society participation in regulatory processes, and strengthen public-private partnerships through global-local alignment.
Water Quality
Ten years of REACH Kenya
A brief overview of work by the REACH programme in Kenya on interlinked groundwater systems, institutions, water quality management and reducing inequalities, illustrating milestones in the Kitui and Turkana Water Security Observatories.
Rethinking responses to the world’s water crises
This perspective paper in Nature Sustainability reframes responses to mitigating the world’s water crises using a ‘beyond growth’ framing. Beyond growth is systems thinking that prioritizes the most disadvantaged. It seeks to decouple economic growth from environmental degradation by overcoming policy capture and inertia and by fostering place-based and justice-principled institutional changes.
Assessing flooding extent and potential exposure to river pollution from urbanizing peripheral rivers within Greater Dhaka watershed
This study looked into the water quality and flooding situation of Greater Dhaka for two successive monsoons through extensive river sampling coupled with the estimation of flooded area and exposed population using remote sensing tools.
REACH Story of Change: Cleaning the tap: Tap hygiene for safer drinking water
Water use behaviour impacts the hygiene of water collection points which can therefore impact water quality. While previous research has focused largely on household hygiene, REACH research has demonstrated how a systematic gap between engineering and hygiene considerations in the water sector is reducing access to safe drinking water. This Story of Change explores how regular cleaning of water point spouts and taps in Bangladesh could substantially reduce the number of people who lack access to uncontaminated drinking water (currently estimated to be between 2-4 billion people worldwide).
Water–Energy Nexus-Based Optimization of the Water Supply Infrastructure in a Dryland Urban Setting
Managing water supply systems is essential for developing countries to face climate variability in dryland settings. However, high energy costs from pumping, water loss due to aging infrastructure, and increased demand from population growth can exacerbate this challenge. In response, this study proposes a methodology that optimizes a Water Distribution Network (WDN) and its management, within the dryland urban setting of Lodwar, Kenya. The findings highlight the potential of WEN-based solutions to enhance the efficiency and sustainability of data-scarce water utilities in dryland ecosystems.
REACH Story of Change: Monitoring and modelling river water quality to protect Dhaka’s river system
This Story of Change describes the establishment of an advanced river water quality modelling system in Dhaka. The system allows decisionmakers to assess the potential impacts of current activities and future growth on river health, and to explore strategies for mitigation such as improved industrial wastewater management and new sewage treatment plants. Ready Made Garment Industry actors have engaged with the model to understand and respond to pollution from their factories.
REACH Story of Change: Improving water security in Ethiopia through integrated use of surface and groundwater resources
As one of Africa’s fastest growing cities, Addis Ababa’s demand for water has sky-rocketed over recent decades due to population growth, increased per capita consumption, rural to urban migration, and growing water demand from industry. Water supplies across the city are already struggling to meet demand, with regularly interruptions to water services exacerbating inequities. This Story of Change explores the range of methodologies that REACH has applied to examine the implications of climate and population growth for Addis Ababa’s water supply. Of particular focus is a first-of-its-kind dynamic water allocation model which integrates both surface and groundwater resources.
Water quality and unseen health outcomes: A cross-sectional study on arsenic contamination, subclinical disease and psychosocial distress in Bangladesh
Health risks from water quality pose a major threat to billions of people globally. Most microbial contaminants have short subclinical periods, compared to chemical contaminants that can take years to manifest, which can translate to less attention in the policy sphere. This paper presents a cross-sectional study of water quality in Bangladesh, assessing both subclinical disease and the psychosocial distress associated with varying water quality issues.
Tracing contaminants of emerging concern in the Awash River basin, Ethiopia
This study focuses on characterization of Emerging Organic Contaminants (EOCs) in the Awash River basin. Characterization of the EOCs was supplemented by chemical analysis of samples from river, boreholes, tap water, and surface water reservoirs. Analyses of environmental isotopes (δ 2 H, δ 18 O, and 222Rn) were used to investigate the exchange of contaminants between surface and groundwater supply sources. The analysis showed new types of contaminants in the water supply sources with potential impact on human and wider environmental health.
