Abstract. Droughts continue to affect ecosystems, communities and entire economies. Agriculture bears much of the impact, in many countries it is most heavily affected sector. Over past decades, efforts have been made assess drought risk at different spatial scales. Here, we present for first time an integrated assessment both irrigated rainfed agricultural systems global scale. Composite hazard indicators were calculated separately using indices based on historical climate conditions...
The devastating impacts of drought are fast becoming a global concern. Zimbabwe is among the countries more severely affected, where have led to water shortages, declining yields, and periods food insecurity, accompanied by economic downturns. In particular, country’s agricultural sector, mostly comprised smallholder rainfed systems, at great risk drought. this study, multimethod approach applied, including remote sensing-based analysis vegetation health data from 1989–2019 assess hazard, as...
Droughts are complex, multifaceted hazards that affect multiple regions of the world and cause severe environmental social impacts. The vulnerability to droughts, however, is complex assess strongly depends on sectoral focus as well geographical context assessment. This report presents results an expert survey was conducted weigh drought indicators according their relevance for agricultural systems domestic water supply. Indicators originate from dimensions (social, economic, infrastructure,...

<p>Drought is a recurrent global phenomenon considered one of the most complex hazards with manifold impacts on communities, ecosystems, and economies. While many sectors are affected by drought, agriculture’s high dependency water makes it particularly susceptible to droughts, threatening livelihoods many, hampering achievement Sustainable Development Goals. Identifying pathways towards more drought resilient societies analyzing drivers spatial patterns risk...
