Monitoring our changing planet
By Houlin Zhao – The Earth is a fragile planet with finite resources to sustain the world’s growing population. As we work together to build a sustainable global economy, spaceborne remote sensors are poised to play an increasingly important role in achieving the United Nations’ Sustainable Development Goals (SDGs).
Indeed, ITU Member States and the global community now see the potential for using Earth observations and geospatial information as fundamental inputs for achieving the SDGs. Remote sensing provides critical information across a wide range of applications, including air quality, disaster management, public health, agriculture, water availability, coastal zone management, and the health of the Earth’s ecosystems.
For example, spaceborne sensing data is used to assess the impact of natural disasters and to be better prepared for hazardous events around the globe. Data from spaceborne remote sensors is also increasingly used to guide efforts to minimize the damage that urban growth has on the environment.
These are just a few examples of how remote sensing measurements — and the science they enable — provide a great service to humanity. This edition of the ITU News Magazine provides more such examples and a wealth of insight into how ITU’s work helps realize the social and economic benefits of Earth observation from space. more (pdf)>
