Abstract: | The demand for rice (Oryza sativa) in Ghana is increasing at a rate of 11.8% from 939, 920 t in 2010. Though
there has been some increase in production it does not match the increase in consumption. This study seeks to determine
the most suitable areas for inland valley rice cultivation using computer based models for selected sites (15km by 15km) in
the Brong Ahafo Region (BAR) and Western Region (WR) of Ghana. A sensitivity analysis was carried out by excluding
the least contributing parameters and varying their weights to determine highly suitable areas. Finally, 12 most sensitive
input parameters were identified from the original 22. These were used to model for five suitability classes (highly suitable,
suitable, moderately suitable, marginally suitable and not suitable). The model results based on parameters having equal
weights showed that 0.5% and 11.8% (BAR); and 1.4% and 21.4% (WR) of the area were highly suitable and suitable
respectively. Using unequal weights, 0.8% and 7.6% (BAR); and 0.9% and 13.6% (WR) of the area were highly suitable
and suitable, respectively. The study successfully mapped out suitable areas for rice cultivation using spatial models based
on limited data set, which can be adopted for use elsewhere. |
