Could you describe your professional career and/or personal experiences related to space technology and water? Where does your interest in those sectors come from?

I started my research career in 2013, with research interests revolving around various environmental concerns that were deeply rooted in water related issues of Pakistan. Having an educational background in Space Science, it was quite intuitive to possess understanding of the very high potential of applicability of Geospatial technologies in the water sector.

From 10 to 13 May 2022, the United Nations Officer for Outer Space Affairs organized the 5th International conference on the use of space technology for water resources management. The conference was hosted in a hybrid format in Accra, Ghana, by the University of Energy and Natural Resources, Sunyani on behalf of the Government of Ghana. The event was attended by several senior government representatives of the host country including Dr. Mahamudu Bawumia, Vice President of the Republic of Ghana, the Honorary Minister of Education Dr.

Le droit humain à l'eau et à l'assainissement 

À quoi ressemble votre routine matinale ? Pour la plupart des lecteurs, je suppose que vous utilisez les toilettes, vous vous lavez les mains et peut-être que vous prenez une douche. Cependant, vous arrive-t-il de vous arrêter pour réfléchir à l'eau que vous utilisez sous la douche ou au savon que vous utilisez pour vous laver les mains ?

Global groundwater supplies

Groundwater accounts for 30% of Earth’s freshwater resources (Shiklomanov 1993) (Figure 1) and is estimated to globally provide 36% of potable water, 42% of irrigation water, and 24% of industrial water – indicating its significant value (Global Environment Facility 2021). Groundwater affords a host of benefits, from providing better protection against drought and microbiological contamination than surface waters, to being generally low cost and accessible to many users.

Introduction

Land subsidence is a global phenomenon and is defined as:

“a gradual settling or sudden sinking of the Earth's surface due to removal or displacement of subsurface earth materials”  - National Oceanic and Atmospheric Administration (2021)

Les réserves mondiales d'eau souterraine 

Les eaux souterraines représentent 30 % des ressources en eau douce de la planète (Shiklomanov 1993) (figure 1) et fournissent au niveau mondial 36 % de l'eau potable, 42 % de l'eau d'irrigation et 24 % de l'eau industrielle, témoignant de leur valeur considérable (Global Environment Facility 2021).

Continuous and reliable global precipitation information is crucial for myriad of weather, climate and hydrological applications. The importance of precipitation in the form of rain, hail, sleet, snow etc. is known to science and clear to a layman. However, it’s quite tricky to measure past precipitation trends or predicting accurate future forecasts. There are three main categories of precipitation data sets available: ground based, satellite-based and blended products of ground and space data (Climate Data Guide, 2014).

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).

Introduction

L’affaissement de terrain est un phénomène mondial et se définit comme :

    "Un tassement progressif ou un affaissement soudain de la surface de la Terre dû à l'enlèvement ou au déplacement de matériaux terrestres souterrains" - National Oceanic and Atmospheric Administration (2021)

With increasing populations, groundwater abstraction also increased as about half of the global urban population access their water through aquifers (Foster et al., 2020). With 74% of the world population depending on it for safe drinking water services and sanitation (WHO and UNICEF, 2021), groundwater plays a vital role in health.

Short description of the Māori community

Our community is made up of direct descendents from our ancestors; Te Huia and Rangiwherowhero. Our Trust is made up of over 700 beneficiaries and is from the Ngāti Maniapoto and Ngāti Apakura tribes which has over 60,000 overall affiliated tribal members.

I have always had an interest for science and the environment and before starting university I was introduced to hydrology which really caught my interest and led me to studying a BSc Degree in Hydrology and Geography.

Short description of community and hydrogeology of the area

Yucatan is located in the southeast portion of Mexico. The total area of Yucatan is 124, 409 km2 and the population (by 2018) was ca. 2.1 million inhabitants. The landscape of the area is defined by a highly permeable karstic soil, a notable absence of rivers or permanent freshwater resources in the surface, and a high number of natural wells or sinkholes (locally called cenotes, from the Maya word t´sonot).

Short description of the Mikisew Cree First Nation community 

Nestled on the northwest shore of Lake Athabasca, Fort Chipewyan is one of the most northern communities in the Regional Municipality of Wood Buffalo. Isolated by nature, Fort Chipewyan can only be accessed by plane or boat in the summer and by a winter road in the winter.

The SADC Groundwater Management Institute will host its 5th SADC Groundwater Conference on 16, 17 & 18 November 2022.

The conference is held annually, with the primary objective of providing a platform for the advancement of knowledge sharing on sustainable management of groundwater at national and transboundary levels across SADC Members States

This year the event will be physically held in Windhoek, Namibia with an online participation option.

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.

The challenge

Water is one of the most important substances on Earth and covers 70% of the planet. However, freshwater makes up a very small fraction with 97% being saline and ocean-based. While the amount of freshwater on the planet has remained fairly constant over time, the world’s population has exploded, meaning that freshwater is threatened by significant forces, like overdevelopment, polluted runoff, and global warming.
