The United Nations Office for Outer Space Affairs (UNOOSA) and the Government of Ghana are jointly organizing a Conference with the support of the Prince Sultan Bin Abdulaziz International Prize for Water (PSIPW) to promote the use of space technology in water management to the benefit of developing countries.
The Conference will be held in Accra, Ghana, from 10- 13 May 2022, hosted by the University of Energy and Natural Resources on behalf of the Government of Ghana.
The Conference is the fifth international event focusing on applications of space technology for water in the series of conferences organised with financial assistance of the PSIPW and the Inter-Islamic Network on Space Sciences and Technology (ISNET). The initial event, on the use of space technology for water management, took place in Riyadh, Saudi Arabia, in April 2008, the second conference was organized in March 2011 in Buenos Aires, Argentina, the third conference in Rabat, Morocco in April 2014 and the fourth in Islamabad, Pakistan in February-March 2018.
Water scarcity and water quality degradation interrelate in the major challenge to secure water of good-enough quality to meet human, environmental, social, and economic needs. According to UNESCO (2020), widespread water quality degradation across the world is the most serious water problem. Three in ten people lack access to safely managed drinking water services; water scarcity affects more than 40 per cent of the global population and is projected to rise. Over 1.7 billion people are currently living in river basins where water use exceeds recharge. Among the challenges to water security are climate change (extreme weather such as floods and droughts among others), an increase in population, increase in water consumption due to domestic use, agriculture, and industry. Pollution also adds to water stress. Water is very closely related to the prevention of disease outbreak, but also a factor that can spread diseases further. In addition, groundwater resources, providing for 30 % of Earth's freshwater resources as well as for better protection against drought and microbiological contamination than surface waters, have been rapidly depleted in recent years; this poses a major threat to global water security, agriculture, energy production and global peace.
The conference relates to a key objective of the Decade for Action on Water for Sustainable Development, 2018-2028: the international community shall "energize implementation of existing programmes and projects", such as the 2030 Agenda for Sustainable Development, the 2015-2030 Sendai Framework for Disaster Risk Reduction, and the 2015 Paris Agreement. Furthermore, the Global Acceleration Framework for SDG 6 and the accelerators communicated therein, are taken into consideration for the planning of the conference:
Finally, specific regional contribution from Sub-Sahara Africa will be encouraged.
The expected outcome of the workshop is to make observations and converge on recommendations for the Groundwater Summit which will take place later in 2022, as well as for the 2023 Midterm Review of the Water Action Decade. Round table discussions on water-related extremes, water quality and health, groundwater as well as capacity building and gaps assessment. The Office for Outer Space Affairs will report to the Committee on the Peaceful Uses of Outer Space on conclusions of the conference and recommendations.
Space technologies such as Earth observation and the resulting data, satellite navigation and communication are increasingly important in observing the Earth's water bodies at regular intervals and in the most remote corners of this planet. Moreover, spin-off technologies such as filtering techniques used in space programmes find their application in water management. This conference will include inputs selected through a call for abstract and will aim at exchanges on the themes listed below:
Floods have become the world's deadliest type of disaster in 2019, having caused 43.5% of all deaths related to natural disasters. An increasing number of events compared to previous years is recognisable. Floods furthermore lead to the highest number of people affected compared to other disasters as they affect human activities and the economy. Technical presentations will focus on available methods, models, tools, data and case studies addressing how floods can be detected or monitored from space, as well as all other space-based solutions that contribute to better management of floods. Topics to be addressed can include, but are not limited to any space-based technology or data used in relation to the below listed:
Water scarcity is a major global challenge. While water demand and population rapidly increase, we are faced with consequences of urbanisation, development pressures, and increased industrial demands on the resource. Water use worldwide has been rising at a rate of 1% per year since the 1980's, driven by population growth, socio-economic development and changing consumption patterns. Global demand is expected to continue growing at a similar rate until 2050, with 20-30% of this increase caused by rising demand in the industrial and domestic sectors. The United Nations SDG 6 Synthesis Report 2018 on Water and Sanitation shows that 2 billion people worldwide live in countries experiencing high water scarcity, and four billion people experience severe water scarcity for at least one month per year. Water stress will increase, as demand for water grows, and the effects of climate change increasingly impact life on Earth at an increasing rate. Innovative scientific solutions are needed to help solving the water crisis, and space technology applications provide tools for effective water resources management. Research and further development of these innovative technologies need to be encouraged and supported worldwide.
Technical presentations in this session shall address how water scarcity is measured, monitored or managed with assistance from or based on space-based technology and data. Presentations will focus on available methods, models, tools, data and case studies to understand water scarcity, its causes and effects, as well as the identification of gaps and needs. Topics to be addressed can include, but are not limited to, any space-based technology or data used in relation to the themes below:
In 2017, 71% of the global population (5.3 billion people) used a safely managed drinking-water service - that is, one located on premises, available when needed, and free from contamination. 785 million people lack even a basic drinking-water service, including 144 million people who are dependent on surface water (WHO, 2020). Furthermore, water quality is a key ingredient to maintaining biodiversity and overall, for sustainable ecosystems and habitats.
Water quality can be measured from space due to specific reflectance characteristics, based on the optical scattering and absorbing properties of their active constituents. These are directly or indirectly related to relevant water quality parameters (indicator) such as turbidity and suspended matter, phytoplankton and its main pigment chlorophyll, detritus, salinity, total phosphorus (TP), Temperature, pH and dissolved coloured organic matter. With the knowledge of their optical characteristics, it is possible to retrieve quantitative values of the concentrations for these water constituents, solely based on the reflectance of light measured by satellite sensors. Different sensors mounted on satellites and other platforms, such as airplanes, measure the reflection of electromagnetic waves by the water's surface (UNSPIDER, 2020 and Graf, 2020).
Technical presentations in this session should cover the methods, tools, variables, observable parameters and data related to water quality monitoring from space, as well as on the ground. Data on the ground is important due to the need for training and validation/verification data, to test new models of space-based water-quality assessment. Themes of the presentation can include, but are not limited to
Globally, at least 2 billion people use a drinking water source contaminated with faeces. Contaminated water can transmit diseases such diarrhoea, cholera, dysentery, typhoid, and polio. Contaminated drinking water is estimated to cause 485.000 diarrhoeal deaths each year. By 2025, half of the world's population will be living in water-stressed areas. In least developed countries, 22% of health care facilities have no water service, 21% no sanitation service, and 22% no waste management service (WHO, 2020). Climate change will cause an additional 250,000 deaths from infectious diseases, including water-borne diseases, in the year 2030 (WHO, 2017).
For cholera, a study from NASA has shown how using precipitation data can help assess the risk of outbreaks (NASA, 2020). But, according to Colwell (2020), what is very much needed besides space-based data is to obtain ground truth measurements, with water samples collected at the time of high risk of cholera, to correlate the presence of cholera bacteria with the agent causing outbreaks. This requires cooperation with meteorological departments of countries concerned to provide data on water, weather, and climate. Technical Presentations in this session on space-technologies contribution to the water-health nexus could cover, but are not limited to, the following themes:
Groundwater accounts for 30% of Earth's freshwater resources provides for about 36% of potable water, 42% of irrigation water, and 24% of industrial water - indicating its significant value. It provides for better protection against drought and microbiological contamination than surface waters. However, a global groundwater depletion in recent years threats global water security, agriculture, energy production and global peace.
Space-based methods for monitoring groundwater, ranging from remote sensing to Geographic Information Systems (GIS) and Global Navigation Satellite Systems (GNSS) for positioning, provide a rapid and cost-effective tool for detecting, extracting, conserving, and testing the vulnerability of groundwater across space and time. Technical presentations in this session can cover, but are not limited to, the following themes:
On one day of the conference, UNOOSA organises a participatory workshop for Indigenous women or female Indigenous communities' gatekeepers and community activists as a side event, to make Indigenous women's voices heard. The aim is to collect indigenous communities' user needs in terms of water resources management and the protection of the water cycle towards the space sector. Participatory design thinking methods and rapid prototyping will be used to ease communication and knowledge exchange between indigenous women, the workshop hosts and supportive community stakeholders. Such rapid prototyping techniques have proven to be successful in eliciting implicit knowledge and manifesting in the prototype. This can aid to overcome potential language barriers. The working language of the workshop will be English.
To re-empower and support Indigenous women in their role as water stewards, as well as to learn from them and include them into the water governance dialogue UNOOSA invites them to this participatory workshop to address challenges. Read more
