The Guardian – Effective policy-making relies on availability of high quality data and nowhere is that more true than in Africa, where a ‘green revolution’ has been spoken about, waited for, but not been realised for decades. Across the continent, national governments and regional planners have never had the data to make proper decisions regarding investment in water resources infrastructure, essential to increase agricultural capacity sustainably.
The main obstacle is Africa’s extremely limited hydro-meteorological observation network. With more measurement stations, and thus better understanding of water availability, and enhanced ability to predict shifting weather patterns, the impact on African harvest predictions and food production could be transformative.
