Despite the benefits of rainwater harvesting technologies on enhancing sustainable agricultural production, farmer still face the number of huddles in implementing such technologies like lack of knowledge, limited space, and limited capital and among others. Rain water harvesting technologies were thought of to sustain agricultural production but its relevance among farmers remains un-documented. The study was about the effects of rainwater harvesting technologies on sustainable agricultural production in Ntutsi and Mijwala Sub-counties, Sembabule District. The specific objectives were to; ascertain the methods of rain water harvesting use for sustainable agricultural production, identify the benefits of rain water harvesting technologies on agricultural production, identify the factors influencing the adoption of rain water harvesting technologies and investigate the challenges faced in implementing water harvesting technologies. The study adopted a cross sectional survey design. Data was collected from 248 farmers. Data management and analysis was done using SPSS version 20 to generate both descriptive and regression statistics. The study identified different rain water harvesting methods use for sustainable agricultural production such as; ridges/tied ridges/furrows, water pans/ponds, sand dams and sub-surface dams as well as rooftop catchments. The study also discovered that technologies like ridges/tied ridges/furrows (x² = 8.305, p=0.005), road runoff water harvesting (x²= 6.048, p=0.001), and a combination of practices (x² = 4.120, p=0.042) had a significant influence on agricultural production. The study also confirmed that gender [AOR = 2.569; (95% CI: 1.239 - 5.327); p = 0.011], level of education [AOR = 1.441; (95% CI: 0.656 - 3.164); p = 0.003], and farm size [AOR = 2.060; (95% CI: 1.021 - 4.154, p = 0.044] were the significant factors influencing the adoption of rain water harvesting technology for sustainable agriculture production in the area.

The study further confirmed that unavailability of labour [AOR = 0.978; (95% CI: 0.169 - 54.570, p = 0.001), lack of knowledge on water harvesting [AOR = 0.333; (95% CI: 0.104 - 34.088, p = 0.005], were some of the challenges faced in the implementation of rain water harvesting technologies. It therefore recommends that farmers be linked to financial institutions since they do not have the capital to invest in RWHTs. This will enable farmers to adopt not only one but many RWHTs.

As a very important textural characteristic, grain size has been widely used by geologists to determine the distance a piece of sediment must have taken before coming to a halt.Sediments,be they clastic or chemical, is determined by their methods of erosion. Clastic sediments being broken down through physical means like water, wind, ice by abrasion. These may give rise to pebbles/gravels,sand,silt and clays.So,to interpret the geomorphological settings of the Çiftlik Basin(paleo or present);sediments must have either been transported from regional to local settings or from within the local settings.Natural characteristics of sediments with recognized grain size composition have been classified using the Udden-Wentworth grain size scale(phi= ?).This is the method that facilitates statistical analysis, graphical representation and geological representation of terrestrial sediments of Oval?ba?, Melendiz and Imamhatip of the Çiftlik Basin. A total of 158 samples were investigated and detailed grain size analysis were done on 41 selected samples. The Oval?ba? (750 cm) OVA1 to OVA15 samples, Melendiz (661 cm) MEL1 to MEL10 samples and Imamhatip (860 cm) IMA1 to IMA 16 samples. The Phi (?) values ranges from ?= -3 to ?=5; from very coarse to very fine grains. Most of the grain sizes were coarse skewed and very poorly sorted, indicative of intra-locality origin of most of the sediments. Skewness which is the measure of symmetry and can either be positive (fine), negative (coarse) or symmetrical. The grain-sizes used are as follows;? 0.062mm(?=5)clays and muds,0.062mm(?=4) silt,0.125mm(?=3)fine sand,0.25mm(?=2)medium sand,0.5mm(?=1)coarse sand,1mm(?=0)very coarse sand,?2mm(?=-1)granules,4mm(?=-2)gravels,8mm(?=-3) pebbles. Their sorting results are as follows; very poorly sorted=7 samples and poorly sorted =34 samples while their skewness is; very fine skew=10 samples, coarse skew=3 samples and very coarse skew=28 samples.
