|Abstract: ||This study evaluates new multi-scale, multi-indicator methods for assessing the vulnerability of crop
production to drought at a national and regional scale. It does this by identifying differences across and
within ten regions of Ghana, a country that faces many climate and crop production challenges typical of
sub-Saharan Africa. In particular, we illustrate how a quantitative national and regional study is a critical
first step in assessing differences in the drought sensitivity of food production systems and show how
such an assessment enables the formulation of more targeted district and community level research that
can explore the drivers of vulnerability and change on a local-scale. Finally, we propose methodological
steps that can improve drought sensitivity and vulnerability assessments in dynamic dryland farming
systems where there are multiple drivers of change and thresholds of risk that vary in both space and
time. Results show that the vulnerability of crop production to drought in Ghana has discernible
geographical and socioeconomic patterns, with the Northern, Upper West and Upper East regions being
most vulnerable. Partly, this is because these regions have the lowest adaptive capacity due to low
socioeconomic development and have economies based on rain-fed agriculture. Within these regions we
find considerable differences between districts that can be explained only partly by socioeconomic
variables with further community and household-scale research required to explain the causes of
differences in vulnerability status. Our results highlight that national and regional scale multi-indicator
vulnerability assessments are a vital (and often ignored) first step in assessing vulnerability across a large
area. These inputs can guide both local-level research and also demonstrate the need for region-specific
policies to reduce vulnerability and to enhance drought preparedness within dryland farming
