0 a semi-arid area or climate (= general type of weather) has little rain but is not completely dry --
As an example, thin impure coal seams can form in places other than where a permanent water table allows peat accumulation, even in semi-arid conditions.
Climate in the district is semi-arid with bi-modal rainfall.
Such scarcity is typical of arid and semi-arid regions where irrigation projects bring former deserts into agricultural production.
Large-scale simulation of wheat yields in a semi-arid environment using a crop-growth model.
Additionally, 11 similar semi-arid grassland sites in the same study area were selected for an investigation of oviposition height and vegetation structure at different sites.
In-terms of vegetation, 80 per cent of the district can be classified as low savanna and arid/semi-arid (ranching zones).
Such systems are most likely to be found in areas with a high annual precipitation, although some semi-arid regions may also be included.
In the semi-arid areas, where this type is quite frequent, the signal is the wetting of the soil.
