Background: Africa's drylands have unique food environments and persistently high rates of wasting and stunting. This article documents findings and experiences from Fill the Nutrient Gap (FNG) processes conducted in 7 Sub-Saharan African countries that include drylands.
Objective: This study advocates for a comprehensive consideration of the specific food environments of drylands using a novel analytical framework and shares findings and best practices for improving food and nutrition security in these contexts.
Methods: Three analyses are combined. Analysis 1 re-analyzes cost and non-affordability of nutrient-adequate diets indicators from FNGs by reclassifying areas as drylands and non-drylands. Analysis 2 uses malnutrition estimates in drylands and non-drylands and examines associations with non-affordability of nutrient-adequate diets. Analysis 3 synthesizes evidence from FNG processes to document how those indicators were used to engage stakeholders and inform nutrition policy and practice in drylands.
Results: The nutrient-adequate diet of a 5-person household was 2.60 USD (41%) more expensive in drylands. A nutrient-adequate diet was not affordable to 71% of households in drylands, compared to 55% in non-drylands. Wasting and stunting prevalence and non-affordability of nutrient-adequate diets were simultaneously high in drylands.
Conclusion: The article presents new evidence that contributes to elucidate specific characteristics of the food environment of Africa's drylands and suggests a framework to improve on those factors systematically. The FNG is innovative in combining an analytical framework with multistakeholder review and dialogue, as well as modeling of possible strategies, to build consensus on possible transformation pathways to improve diets in drylands.

Previous research indicates that African savanna elephants change their movements preceding or coincident with local rainfall and it has been suggested that they respond to thunder in remote storms-perhaps reading seismic cues. We therefore aimed to test if elephants in Northern Kenya adhere to distinct daytime movement states between the wet and dry periods, and whether their abrupt movement changes precede local wet periods in response to lightning strikes from a specific compass heading. In our study site, lightning to the North and East often preceded local rainfall and could possibly be used to anticipate local wet periods, but local rainfall appears a more likely trigger of behavioural change.

The importance for multi-dimensional priority-setting of agricultural innovations is growing, given that agricultural technologies usually play multiple roles for smallholder farmers. This study assesses agricultural technologies based on their multi-dimensional impacts in the drylands of sub-Saharan Africa and South Asia. The study applies the Technique for Order Preference by Similarity to an Ideal Solution (TOPSIS) to a set of promising agricultural technologies and uses three outcome criteria: the benefit-cost ratio, poverty reduction, and nutrition security.

Drylands' poly-extreme conditions limit edaphic microbial diversity and functionality. Furthermore, climate change exacerbates soil desiccation and salinity in most drylands. To better understand the potential effects of these changes on dryland microbial communities, we evaluated their taxonomic and functional diversities in two Southern African dryland soils with contrasting aridity and salinity.

This study gives empirical evidence on the drivers of land use change by conducting a qualitative assessment and then using time series data to quantify the relationship between land use land cover change and factors that cause the change. Vector autoregressive models with exogenous variables were used to analyze the time series data. The findings revealed demographic and environmental factors were the primary causes of land use and land cover change.
