Having reliable and timely population distribution data can make a life or death difference for individuals facing crises or living in conflict-ridden regions. These data are also essential for development decision-making and planning and for monitoring progress towards the UN Sustainable Development Goals (SDGs) established by the international community. We need to know where people are located, what conditions they are facing, what infrastructure is available, and what basic services they can access. We also need to ensure that no one is left off the map in pursuit of meeting the SDGs.
Gridded population data, which often use remote sensing inputs to improve the spatial allocation of population within a country, are vital for all these purposes. Together with the growing variety of applications that require spatial population data, there is now a bewildering array of population grids, and users need to know which ones are most suitable for their applications…
read moreThe United Nations Office for Outer Space Affairs (UNOOSA) and the National Aeronautics and Space Administration of the United States Government (NASA) signed a landmark Memorandum of Understanding (MoU) on 17 December 2020 pledging cooperation in areas of science and technology to support the peaceful uses of outer space.
The MoU brings together NASA's wealth of open-source spacecraft data, tools, and expertise and UNOOSA's unique position as the only UN entity dedicated to outer space affairs, to expand global opportunities to leverage the benefits of space. The partners will design capacity-building programmes, particularly for institutions in countries that do not yet have or that are developing space capabilities, to help them access space.
Together, UNOOSA and NASA will develop ways to leverage the Artemis programme as part of UNOOSA's Access to Space 4 All Initiative, which offers opportunities for international researchers and institutions, especially in…
read moreIn collaboration with the National Commission for Space Activities (CONAE) of Argentina, the Mexican Space Agency (AEM) recently launched a digital platform to improve the integration of satellite data for environmental monitoring in Latin America. The Comprehensive Regional Satellite Information System (SIRIS) provides access to satellite information in order to enhance decision-making and facilitate disaster management.
The SIRIS platform provides access to satellite imagery for different areas. The platform supplies information on the agriculture and forestry sector to better monitor the impact of natural disasters on agricultural production and woodland. It also offers up-to-date and archived data on fires to strengthen early warning and build long-term resilience. On floods, information provided by SIRIS indicates the water level to improve damage evaluation of the impacted area and facilitate humanitarian relief. In…
read moreA new report by the world’s largest humanitarian aid network highlights global disasters, populations most vulnerable to them and the efforts of local institutions in preventing, preparing for and responding to them. The 2020 edition of the World Disasters Report, “Come Heat or High Water”, was launched virtually from the offices of the International Federation of Red Cross and Red Crescent Societies (IFRC) in Vienna on November 16. This year’s report discusses climate- and weather-related disasters and their humanitarian impact. It argues for the usefulness of smart financing and space-based information in disaster management support.
The report warns that the global effort to address climate change is leaving behind countries…
read moreOfficially launched in 2015 by the National Aeronautics and Space Administration (NASA), the SMAP mission is an orbiting satellite that measures the amount of wetness in the top layer of soil incrementally every 2-3 days. These Soil Moisture Active Passive (SMAP) measurements rely on radiation frequencies that point to different levels of moisture on the surface of earth’s soil and are useful for scientists because it allows them to construct maps indicating the level of soil moisture globally. Acknowledging the relevance and usability of this data for the field of disaster management, NASA recently integrated the SMAP data into its Disasters Mapping Portal.
The Disasters Mapping Portal has been developed by the Geographic Informations Systems (GIS) Team at NASA in an effort to make their satellite data…
read moreThe European Commission plans to rapidly expand its environmental monitoring programme Copernicus. For this purpose, the European Space Agency (ESA) recently pledged 2.55 billion Euros towards contracts to advance the production of six new Copernicus satellite missions. The final of the six contracts was signed last Thursday between ESA and Thales Alenia Space for a mission that will provide new and important information to climate research and disaster management.
The high-priority Copernicus Radar Observation System for Europe in L-band (ROSE-L) mission is planned to launch in 2028 for a period of 7.5 years. The ROSE-L mission will orbit Earth every few days at an altitude of 690km and will carry a L-Band synthetic aperture radar (SAR). With a wavelength of approximately 23cm, an…
read moreA new report outlines the impact of Global Human Settlement Layer (GHSL) data on various policy areas. The 2020 edition of the “Atlas of the Human Planet”, recently published and launched virtually by the Joint Research Centre (JRC) of the European Commission as a deliverable to the Group on Earth Observations (GEO) Human Planet Initiative, explores the impact of GHSL data on various policy areas, including disaster risk management.
GHSL data refers to “global spatial information, evidence-based analytics and knowledge describing the human presence on the planet”. This data relies on spatial information from Landsat 8, Sentinel-1 and Sentinel-2. It is mainly cost-free and…
