Although crimes and the modus operandi of perpetrators across the world change constantly, some policing tools, especially in developing countries, remain the same. This study sought to assess Kenyan police officers’ satisfaction with the use of paper maps and push-pins (manual tools) in crime analysis, and identify challenges to the adoption of computerized tools such as geographical information systems (GIS) at a time when most operations are driven by technology. A descriptive survey targeting 120 Kenyan police officers was carried out at the National Police Service (NPS) headquarters in Nairobi, but only 94 (78.3%) officers responded. The study reveals that 42.3% of respondents found manual tools to be useful in crime mapping and spatial analysis, whereas 67.8% felt that they were easy to use. The study indicates that 55.0% of respondents were satisfied with manual crime mapping and spatial analysis, mainly because it was easy to use. The study also identifies several challenges to the adoption of GIS in crime analysis. The study concludes that majority of respondents found manual crime-mapping tools to be easy to use, but less useful although still usable in the absence of alternatives. The NPS should consider implementing pilot projects of computerized crime mapping and spatial analysis to allow stakeholders to assess police operations against multiple platforms.

Erosion is a global problem that destroys soil and adversely affects ecosystem productivity. Soil erosion generally involves many processes but the major activities involve particles being transported and deposited to another location. With an increasing population, soil erosion, water availability, energy production, and biodiversity loss are some of the most pressing environmental problems around the world. Erosion is a hazard associated with agriculture in tropical and semi-arid areas. Kambiti sub catchment is part of the upper Tana catchment. The upper Tana catchment includes 25% of Kenya gazette forest. A large area of land has been degraded, resulting in a drastic reduction in surface water availability during the dry season and poor-quality water during the wet season caused by high silt levels. The main objective of the study is to assess erosion hazards using RUSLE model in Kambiti sub catchment area, Murang’a County. The specific objectives of the study were to determine the effect of rainfall erosivity and soil erodibility factor in Kambiti Sub catchment area in Murang’a County, to determine  effect of slope factor to soil loss in Kambiti Sub-catchment area in Murang’a County, to determine the effect of crop protection and management factor in Kambiti Sub catchment area in Murang’a County to soil loss and to determine the strategies for management of soil and water in Kambiti Sub catchment area in Murang’a County. Data was collected from the catchment and analyzed using arc Geographical Information System to obtain the specific parameters in the revised universal soil loss equation model. Interpolation method was used to determine the mean annual precipitation. The k factor is a function of soil texture. Shape file for geological structure for Kenya was obtained from Kenya Agriculture and livestock Research Organisation and analyzed by use of arc GIS to obtain soil erodibility factor. The slope factor was analyzed using digital elevation model from arc view. Digital elevation model was gotten from STRM download. The C factor was derived from Landsat imagery from sentinel of 30metres by 30 metres. It was further analysed by unsupervised classification from Arc GIS. The sentinel clip of Kambiti sub-catchment was joined with ground trothing observations. The results were useful in estimation of soil loss therefore profiling the areas prone to soil loss. Study findings indicated rain drop impact and runoff were primarily responsible for causing erosion in Kambiti sub catchment. Anthropogenic factors played an important role in amplifying the severity of the damage, such as persistent vegetative degradation and destruction of soil structure due to organic matter depletion and routine shallow tillage. In recent years, erosion control has been hampered by the occurrence of gaps in knowledge regarding the integrated nature of erosion processes, leading to land damage caused by rill and inter-rill erosion going unaddressed. Poor people and those lacking capital to invest in reclaiming land are the main causes of abandoning degraded land. Through strategic awareness campaigns and education, soil erosion will be assessed and the knowledge gap will be closed. Participation of farmers in land use decisions is inevitable as it ensures that people who utilize land resources are recognized as equal partners in identifying problems and designing solutions. It was also recommended that Identification and operationalization of alternative off-farm income.

Kiladeda River in Pangani Basin, Tanzania, plays a vital role of providing water for agricultural activities of the sub catchment. However, it is experiencing a problem of inequitable distribution of irrigation water among farmers. Cross-sectional data was collected from farmers both in upstream and downstream using questionnaires, while river discharge measurements were conducted in referenced spot gauging stations. WEAP model was used to analyze water demand and allocation among farmers. Furrow irrigation (94%) and plastic buckets (6%) were the main irrigation water management practices. The results of WEAP model revealed a water shortage of about 53.6% of the total irrigation water required. The annual irrigation water demand and unmet demand were 13.93Mm3 and 7.47Mm3 respectively, and are both expected to increase twice in 2020. This high water demand for irrigation could be the main cause of excessive water abstraction. A partnering approach is recommended to improve irrigation water management; reviewing of laws, regulations and water rights.
