Previous studies have established that the purpose of sustainable natural resource management and development is to ensure that resources are utilised in a way that does not adversely affect their on-going quality for current and future populations. But it is noted that factors such as climate change, population growth, environmental pollution, agricultural intensification, and urban expansion can seriously affect the use and availability of resources for future generations. Therefore, the appraisals of critical
developmental issues call for methodologies and technologies that will enable assessment of current natural resource systems, risks and needs, and provide a means for ensuring sustainability in the future. To this end, Geospatial Science such as spatial
analytical techniques, earth observation satellites (active and passive), Volunteered Geographic Information and crowd sourcing are new and existing technologies to map, monitor and sense our scarce natural resources for environmental sustainability.
