| dc.description.abstract | The study is an attempt to strengthen the efficacy:ency and effectiveness of the information systems on the protection of the environment against its pollution and degradation due to misuse and abuse of petrochemicals. Its objective is to facilitate the access to timely and correct information for use by decision makers, scientists and researchers, agricultural extension workers as well as by the farmers and others interested in the adverse effects of agrocbernicals to the environment. The study considers the existing information infrastructures within the Tanzanian socioeconomic setup, with a view of exploring how the people could have a better access to information on adverse effects of petrochemicals. The inherent weaknesses in the existing petrochemical infiltration infrastructures have been indicated. In order to overcome the apparent weaknesses, it is proposed to establish a computer-based Information Support System on the Effects of Petrochemicals on the Environment in Tanzania (lSSEAED within the National Environment Management Council (NEMC). The objectives, functions and structure of ISSEAET are elaborated. The justification for the study is the need to improve on the collection, analysis and dissemination of information on the adverse effects of agrochemicals since the latter are playing a significant role in agriCUlture. Agrochemicals are credited for increasing farm yields, but they are also associated with numerous hazards to the health of the people and of the environment. The methodology adopted in the study includes, the use of sets of questionaire for the collection of data which have been used in the designing of different databases. Questionaires have also been used in ascertaining the information needs of the potential users ofISSEAET. Documentary sources, as well as interviews and on-site visits, also have been used for the collection of data. The information system being proposed recognizes, however, the need for flexibility in order to accommodate the changes in Information Technology and in the country's political and sociology-economic orientation. ISSEAET is important in the country's desire to establish a computerized National Petrochemical Information Network System. Access to relevant information on how to use agrochernicals while, at the same time, keeping the environment clean is a challenge which ISSEAET intends to meet by the provision of its information products and services. | en_US |
