| Summary/Abstract |
Remotely sensed data can be used to understand and devise measures to address important global issues such as climate change, disaster and disease outbreak. National Aeronautics and Space Administration (NASA) is one of the largest producer and gatekeeper of satellite earth observation (EO) data that plays a crucial role in ensuring that these resources are used for solving global societal problems. However, the extent of remote sensing application is highly disparate in different parts of the world. This paper provides a general overview of key societal applications that have been enabled globally with the use of EO data. It also summarizes the impact of various NASA-supported programs for promoting applications on the targeted beneficiary communities. The themes addressed here are land cover/land use mapping, carbon biomass assessment, food security, disaster management, water resources, ocean management and health and air quality. The paper also argues for capacity building that is crucial to building sustainable solutions when using EO data for science-based decision making.

| Summary/Abstract |
Africa is advancing in research and development (R&D) in space with a growing investment in satellites for communications and Earth observations, astronomical observatories, space launch vehicles, and ballistic missiles. These efforts are designed to develop capacity in space science and to advance human development and security in Africa. Nevertheless, there are emerging concerns within and outside the continent on the cost of R&D in space and the public priority it is receiving, given developmental priorities in Africa. This article examines the state of space-related R&D in Africa, its cost and benefits, and the imperative for a balanced policy priority and investment. Leading African states are encouraged to intensify international partnerships, internalize relevant know-how, improve their competitiveness, and support regional initiatives to minimize the domestic cost of spreading benefits of space technology across the continent.
