Each measurement was made on plants under monitored control conditions i.e. in the absence of drought constraint.
Cassava is an important root crop to resource-poor farmers in marginal areas, where its production faces drought stress constraints.
The study highlights the importance of supplemental irrigation, even in a humid climate, and the risks that future droughts and/or constraints in water resource availability might have on agricultural systems, livelihoods and the rural economy.
Low phosphorus (P) availability and drought are primary constraints to common bean and cowpea production in developing countries.
Despite the importance of drought as a constraint, efforts need to be accelerated to develop drought-tolerant rice cultivars.
This biotechnological strategy combined with conventional genetic breeding approach should contribute to overcome the serious constraint – drought stress – for soybean production.
These physical and mental health co-morbidities are exacerbated by environmental constraints including drought, flood and bushfires, access to rural healthcare, geographic and social isolation, costs of health service access and the distance-decay effect [ 11].
Drought is the major constraint to productivity and the cause of yield instability in rainfed lowlands.
