Abstract:

The application of computer science has led to advancements in various sectors of economies including agricultural production, manufacturing and marketing. Computer algorithms have been used for prediction. There has been immense interest and research on meteorological prediction aimed at addressing drought. This has been achieved through the development of various drought indices. Some researchers have studied drought prediction by applying computer science solutions. However, critical issues related to agricultural drought have not been well addressed. This study looked at issues related to agricultural droughts, with the aim of developing an efficient and intelligent agricultural drought prediction system. By using a case study approach and knowledge discovery data mining process this study was preceded by literature review, followed by analysis of daily 1978- 2008 meteorological and annual 1976-2006 maize produce data in Voi Taita- Taveta (Coast province, Kenya). The design and implementation of an agricultural drought prediction system for meteorological data preprocessing, classification algorithms for training and testing as well as prediction and post processing of predictions to various agricultural drought aspects is presented. To overcome the problem of geographical differences the solution allows choice of area latitude during the preprocessing. To come up with the agricultural drought meteorological data relationships, the study was forced on the two different datasets. Meteorological data is on daily basis while maize produce data is on annual basis. The datasets difference constraint was overcome by performing analysis of metrological data on monthly, seasonal and yearly basis so as to properly relate the two data sets. Further to overcome the limitation of data incompatibility the analysis of each dataset was done independently. Literature review on drought occurrences verified the results of associated maize produce and meteorological data analysis. Maize was used as a study crop since it is the staple food and also most sensitive to agricultural drought compared to other seasonal crops. The solution was evaluated by comparison of predicted to actual 2009 data and Kenya Meteorological Department (KMD) records. The evaluation of our study results indicated consistency with the KMD 2009 outlook. The report concludes that the application of classification algorithms together with past meteorological data can lead to accurate predictions of future agricultural drought. The recommendation is that future study can be based on designing a solution for multiple regions with multiple crops as well as integration of indigenous knowledge in designing a solution to agricultural drought problem.
