The global challenges facing our planet are daunting. Climate change is well underway, bringing in its wake natural disasters of an unprecedented scale, The ocean is warming and its health deteriorating with impacts on sea level rise and the livelihoods of millions of people. Biodiversity is dramatically shrinking, while pollution has become ubiquitous. And still today, 32% of the world’s population does not use the internet, as high-speed fixed broadband remains unavailable in remote and sparsely populated regions, including in some OECD countries.
Efforts to respond to these and other challenges have benefited from advances in space technologies:
In OECD countries, space-based systems already support more than half of the most frequently designated critical infrastructures and services, such as transportation, energy, food supply and law enforcement.
Space-based observations provide more than half of the essential climate variables that are used to monitor climate change, with atmospheric observations and ocean observations, such as sea surface temperatures, ocean colour, and land cover with terrestrial vegetation types and ice caps.
In 2022, newly launched satellites detected more than 1 000 human-induced methane super-emitter events in landfills, demonstrating how greenhouse gas emissions could be better monitored globally.
Space applications are also increasingly used in developing countries to monitor the environment, forests and food production, contribute to disaster prevention and emergency response; as well as to provide communication services via satellite TV and radio. Space-related official development assistance accounted for more than 700 million constant USD between 2000 and 2021, with commitments rising significantly recently thanks to targeted efforts by several OECD countries.
This has been achieved thanks to decades of mainly public investment. However, more needs to be done to secure the economic sustainability of critical missions, create the right policy and regulatory environment for innovative solutions and increase user uptake of satellite data for a broader distribution of benefits.
