Interview with Hannah Ritchie, PhD student in WASH at Cranfield University

Hannah has always had a love for the outdoors and especially for being by the sea. From her interest in both hydrogeology and development, developed during her undergraduate studies in geology and her travels respectively, she is now undertaking a PhD in WASH, researching water security in rural communities in Kenya. Hannah undertook a six-month internship with Space4Water at UNOOSA in 2021, where she developed her understanding of the importance and application of space-based technologies in the water sector. She believes that groundwater and sanitation are two areas where space technologies are currently under-exploited but in which they hold a lot of potential.

Spin-off technologies for water

Have you ever considered how technological innovations from the space industry can benefit us here on Earth? You might be surprised to hear that non-space applications from space programmes are extensive.

Call for local perspectives: Groundwater challenges

Local perspectives and case studies

The aim of the local perspectives and case studies feature is to learn about gaps in water resource management from affected individuals, communities, civil society, professionals, researchers or organisations in the field to identify needs or potential solutions that space technologies could contribute to.

Can space technologies help improve WASH provision in camps and informal settlements?

The Human Right to water and sanitation

What does your morning routine look like? For most readers I’d assume you use the toilet, wash your hands, and maybe take a shower.  However, do you ever stop to consider the water you use to shower, or the soap you use to wash your hands? Often, especially in developed countries, these things are taken for granted, rightly considering access to adequate water, sanitation, and hygiene (WASH) as basic Human Rights (Figure 1).

The progress and potential of Sustainable Development Goal 6 and how Space Technologies contribute

Transitioning from the Millennium Development Goals (MDGs) to the Sustainable Development Goals (SDGs)

The world of WASH (water, sanitation, and hygiene) has come a long way in 30 years. Between 1990 and 2015, 2.6 billion people gained access to improved drinking water, whilst 2.1 billion gained access to improved sanitation (Unicef and World Health Organisation 2015). That’s a lot of people. But is it enough? 

Water Quality Indicators – an Overview

Clean drinking water is a precious resource. It is the basis of our daily life and decides like no other substance about our health and well-being. It is therefore important to ensure that the water for everyday use meets the highest quality criteria. But what is meant by the term water quality and how can water quality be measured and compared? This question will be addressed and explained in more detail in the following sections.

GEO AquaWatch Stakeholder

GEO AquaWatch

AquaWatch is an Initiative within the Group on Earth Observations (GEO) that aims to develop and build the global capacity and utility of Earth Observation-derived water quality data, products and information to support water resources management and decision making.

Goal

The goal of the AquaWatch Initiative is to develop and build the global capacity and utility of Earth Observation-derived water quality data, products and information to support effective monitoring, management and decision making.

Objectives

The objectives to achieve this goal are:

University of Stirling

The University of Stirling (www.stir.ac.uk) was founded by Royal Charter in 1967 as the first genuinely new university in Scotland for over 400 years and embraces its role as an innovative, intellectual and cultural institution. A research-led university with an international reputation for high-quality research directly relevant to society’s needs, Stirling aims to be at the forefront of research and learning that helps to improve lives.

United Nations Office for Outer Space Affairs

The United Nations Office for Outer Space Affairs (UNOOSA) works to promote international cooperation in the peaceful use and exploration of space, and in the utilisation of space science and technology for sustainable economic and social development. The Office assists any United Nations Member States to establish legal and regulatory frameworks to govern space activities and strengthens the capacity of developing countries to use space science technology and applications for development by helping to integrate space capabilities into national development programmes.

Capacity Building and Training Material

ARSET - Integrating Remote Sensing into a Water Quality Monitoring Program

Overview:

These training webinars will focus on integrating NASA Earth observations into water quality monitoring decision making processes. This will include a brief overview of data products used for water quality monitoring, an overview of aquatic remote sensing-specific criteria, methods and best practices, obtaining NASA Earth observation data for water quality monitoring, and practical skill building in image processing for water quality monitoring of coastal and larger inland water bodies. 

ARSET - Processing Satellite Imagery for Monitoring Water Quality

Overview:

Polluted water influences all aspects of life, including people, animals, and the environment. NASA satellite observations provide near real-time information about water quality. This freely available data can help decision-makers in their work. Satellite data can have applications for managing drinking water, public health, and fisheries.

Water Quality Assessment Capacity Building and Training Material

Water Quality Assessment

Module

This module consists of four Courses with mainly theoretical background and one Course with a final assignment. Following the DPSIR structure (Driving forces, Pressures, State, Impact and Response), we will look first at some causes and consequences of water pollution and then learn how to measure and evaluate water pollution.

Bhuvan Ganga App Software/Tool/(Web-)App

Bhuvan Ganga App

Bhuvan Ganga App is ISRO’s mobile application developed to enable public to collect and report information on various pollution sources that affects the water quality of river Ganga. This mobile app will provide a platform for crowd sourcing to monitor pollution in river Ganga and enable decision makers at National Mission for Cleaning Ganga (NMCG) under Ministry of Water Resources, River Development & Ganga Rejuvenation, Government of India to prioritize interventions.
