Abstract This study ascertained the socioeconomic determinants of farmers’ knowledge on soil and water conservation technologies in Dry zones of Central Highlands of Kenya involving 400 farming households. Results showed that the majority of the farmers had inadequate knowledge on the use and benefits of soil and water conservation technologies. The socio-economic factors that influence knowledge levels of the knowledge-intensive technologies were education level, gender, perceptions on so...
Abstract Rainwater harvesting (RWH) is promoted in arid and semi-arid areas for increased yields. Planting pits are RWH systems that are used for collecting rainwater and runoff. Recently, there has been increased interest in economic and environmental benefits of agricultural technologies for sustainable development. To contribute to this knowledge, economics of Chololo and Five by Nine planting pits and sorghum and pigeon pea mulch was investigated at two sites in semi-arid Eastern Kenya f...
Abstract Most countries across the world are still adopting the crisis management approach in their drought management efforts. This approach has been criticized due to its reactive nature. Researchers emphasize the need for a more strategic and proactive drought management approach. In Kenya, the National Drought Management Authority (NDMA) was constituted to manage the persistent droughts that are experienced in the country. However, there is paucity on research focusing on the strategic m...
Abstract Human activities have potential adverse effects on freshwater ecosystems, which sustain a wide range of ecosystem services such as the provision of potable water, nutrient cycling, and a habitat for organisms such as decomposer macro-invertebrates. The effect of these activities with regard to water quality and invertebrates has been established and well documented. However, information on the effect of human activities on leaf litter breakdown as an indicator of river ecosystem int...
Abstract Human-related activities are known to have deleterious effects on the water quality of aquatic ecosystems globally. However, there is limited information on the impact of similar perturbations in tropical regions, especially the River Chania in Kiambu County, Kenya, which is an important source of water for humans and animals and also provides habitat for a variety of flora and fauna along its length. The aim of this study was to determine the spatial and temporal variations of sele...
Abstract The global demand for fresh water resources has been increasing over the years due to population growth, urbanization, industrialization, climate change and the global warming effect. The available water resources have reduced over time leaving a water demand deficit. Recycling and reuse of greywater has been touted as one of the strategies to augment the existing water resources. This study characterized the greywater from students’ hostels and prepared biochar from banana stalks...
Abstract Water insufficiency due to scarcity, poor distribution and high variability of rainfall in the Central Highlands of Kenya (CHK) and a decline in soil fertility have contributed to a continuous decrease in water productivity. To increase food production to match the growing population, soil management practices that ensure improved water productivity should be embraced. The study, therefore, sought to characterize rainfall and to establish the effects of selected soil management prac...
Abstract Drier parts of Kenya’s Central Highlands endure persistent crop failure and declining agricultural productivity. These have, in part, attributed to high temperatures, prolonged dry spells and erratic rainfall. Understanding spatial-temporal variability of climatic indices such as rainfall at seasonal level is critical for optimal rain-fed agricultural productivity and natural resource management in the study area. However, the predominant setbacks in analysing hydro-meteorological...
Abstract This study examined the extent of seasonal rainfall variability, drought occurrence, and the efficacy of interpolation techniques in eastern Kenya. Analyses of rainfall variability utilized rainfall anomaly index, coefficients of variance, and probability analyses. Spline, Kriging, and inverse distance weighting interpolation techniques were assessed using daily rainfall data and digital elevation model using ArcGIS. Validation of these interpolation methods was evaluated by compari...
Abstract Lake Naivasha, Kenya, is a fresh water lake currently experiencing severe environmental problems as result of pollution from agricultural effluents and urban water surface runoff, uncontrolled water abstraction, improper land use practices in the catchment area and proliferation of wetlands’ invasive species. These problems are exacerbated and compounded by changes in climate and inadequate conservation interventions. To deal with the pollution problem, flower farms around the lak...
Abstract/Overview Rainfall variability characterized by intense rainfall, more frequent droughts and unpredictable rainfall has devastating effects on rain-fed agriculture and dairy production in particular. Over the years, dairy cattle farmers in Keumbu Division have experienced fluctuations in milk production. The purpose of this study was to assess the coping and adaptation strategies employed by small-scale dairy farmers to counter the effects of climate change induced rainfall variab...
Abstract/Overview Different scholars have looked at the general economic impacts of the land reforms and legal implications at national level. However, a few studies have been done on economic history in Gusiiland. This study aimed at analyzing the impact of the colonial land tenure reforms on the Abagusii customary land tenure practices in Gusii, Kenya. This study used the articulation of modes of production theory to analyze the effects of land reforms on the Abagusii community from 189...
