Over the past 30 years, West Africa's population has more than doubled; growing 2.7% annually and by 2030, 490 million people are expected to live in the region, placing additional demands on natural resources in the agricultural and forestry sectors. The West African Sahel and Sudanian region is an epicenter of land cover change hotspots which have not been sufficiently documented, due to the inability of multi-temporal moderate resolution observations to adequately resolve widespread sub-hectare changes. Documenting the complex transformation of land cover in WA has been of interest to the remote sensing and policy communities for decades, yet understanding underlying drivers has remained elusive due to a lack of adequate fine-scale observations from space. Widespread reforestation in dryland agriculture regions, expansion of irrigated rice cultivation, dryland agriculture extensification and clearing of natural savanna have been reported, but are poorly mapped and quantified.

We contend multi-source land imaging using very-high resolution imagery (VHR), a time series of multi-spectral and SAR data, as well as High-End Computing (HEC), our Team can significantly improve policy-relevant land cover change information in WA. We will inform policy and investment initiatives by quantifying land cover changes due to agricultural extensification of irrigated rice and dryland cultivation, and afforestation or tree cover loss, using VHR imagery, plus a combination of medium resolution optical and SAR time series.
