Type 2 diabetes mellitus (T2DM) prevalence is increasing at alarming rates posing significant health problem in Tanzania. Urbanization with economic advancement has led to lifestyle behaviors such as high intake of dense ...
The Role of Response Farming Rainfall Forecasts in improving the performance of Agronomic Adaptation Strategies

Mahoo, H.F.; Tumbo, S. D.; Rwehumbiza, F. B.; Admassu, H. (2016)

Farming by resource-poor and inadequately informed farmers with fixed best-bet strategies under seasonal variability and changing climate in the semi-arid Central Rift Valley of Ethiopia has often proven to be of very ...
Root zone soil moisture redistribution in maize (Zea mays L.) under different water application regimes

Mthandi, John; Kahimba, Fredrick C.; Tarimo, Andrew K.P.R.; Salim, Baandak A. (SciRes, 2013)

Soil moisture availability to plant roots is very important for crop growth. When soil moisture is not available in the root zone, plants wilt and yield is reduced. Adequate knowledge of the distribution of soil moisture ...
ScalA-FS: expert-based ex-ante assessments of local requirements and success potential of upgrading strategies for improving food security in rural Tanzania

Uckert; Graef, G.F; Faße, A; Herrmann, L; Hoffmann, H; Kahimba, F.C; Kissoly, L; König, H.J; Lambert, C; Mahoo, H; Makoko, B; Mrosso, L; Mutabazi, K.D; L. Mwinuka, L; Schäfer, M.P; Schindler, J; Sieber, S; Swai, E; Yustas, Y.M (Springer, 2018)
