Malawi, South Africa, Zambia, Zimbabwe, Botswana, Lesotho and Namibia have all been affected by the drought. Crop failures in South Africa, Zambia and Zimbabwe – the largest maize producers in southern Africa – have destabilised food security in the whole region.

Maize is the preferred staple of most of southern Africa. In Malawi it supplies two-thirds of national calorie intake. Nine out of 10 farming households produce maize and devote over 70% of their land to growing it. Most farming households are vulnerable to the rainfall patterns. Over 90% of farming households in the country rely solely on rain to irrigate their maize plants.

AbstractNitrogen (N) is an important nutrient for crop growth. However, the overuse of N fertilizers has led to a series of devastating global environmental issues. Recent studies show that multiple datasets have been created for agricultural N fertilizer application with varied temporal or spatial resolutions, nevertheless, how to synchronize and use these datasets becomes problematic due to the inconsistent temporal coverages, spatial resolutions, and crop-specific allocations.
