Abstract: To attain optimum productivity of the land and ensure sustainability environmental resource suitable land use decisions are vita. The aim of this paper is to evaluate physical land suitability of maize and sorghum crops using GIS by identify areas with physical constraints for maize and sorghum land uses and the management requirements. The quality rating for each crop type was evaluated against the recommended threshold level for rain fed agriculture. Each crop type was rated for rain fed agriculture suitability following standard FAO guidelines. The findings of the study revealed that, The results of the climate considering, temperature suitability of Efa Gudina watershed show that is highly suitable (S1) for both Maize and Sorghum varieties production under rain fed conditions in all mapping unit. But climate considering, rain fall suitability show that marginally suitable (S3) for Maize and permanently not suitable (N2) for sorghum in all mapping unit. In addition, landscape suitability evaluation showed that, soil mapping units (SMU) 0, 1, 2. 3, 4, & 19 is highly suitable and SMU5 to 13 is marginally suitable (S3) for both rain fed maize and sorghum production. On the other hand, soil mapping units SMU14, 15, 16, 17 & 18 and SMU20, 21, & 22 permanently not suitable (N2) for both maize, and sorghum production due to problems related to sever erosion hazard. Therefore the study suggested that most of the limitations can be improved through improving and sustaining soil management so as to attain the potential suitability of the watershed. However, land suitability for growing crop is not only limited by the selected physical constraints but also socioeconomic factors.

Abstract: This study examined the factors affecting the adoption of new farming technique among seaweed farmers in two villages, namely Muungoni and Nyamanzi in Zanzibar. The nature of this study is quantitative. The study was governed by four objectives which were to examined the effect of environmental factors to the adoption of new seaweed farming technique, to examined the effect of social-psychological factors to the adoption of new farming technique, to examined the effect of institutional factors to the adoption of new seaweed farming technique, to examined the effect of economic factors to the adoption of new seaweed farming technique. Survey questionnaire was used as a method of data collection from 45 respondents using simple random techniques. A Descriptive analysis technique was used for data analysis and interpretation using SPSS V.23, and the findings were summarized in percentages and presented in tables and figures. The findings of this study indicated that environmental factors; social-psychological factors; institutional factors; and economic factors have effects on the new seaweed farming techniques in Muungoni and Nyamanzi Zanzibar. Therefore, the study recommended that the use of new seaweed farming technique can be achieved through effectively addressing all challenges, provision of financial assistance to the seaweed farmers, and awareness rising and sensitization through workshop campaigns, conference presentations, meetings, and discussions.
