    Factors Influencing Adoption of Woodfuel Energy Saving Technologies in Nakuru County, Kenya
    (2013) Kung'u, J.B.; Njogu, Paul K.
    There have been efforts to promote use of woodfuel conservation technologies. These technologies include the improved charcoal stoves, the improved fuelwood stoves and the fireless cookers that can save woodfuel of upto 50%. This study was carried out to determine the social economic factors influencing adoption of these technologies. Income of the household and level of education were positively correlated to acquisition and use of the energy saving technologies. While the numbers of dependants and cost of improved woodfuel energy saving technologies were found as some of the social economic factors influencing adoption of these technologies

    The Potential of Zai Pit Technology and Integrated Soil Fertility Management to Enhance Crop Productivity in Semiarid Regions of Sub-Sahara Africa: A Review
    (Infogain Publication, 2023) Kebenei, Mercy Cheruto; Mucheru-Muna, Monicah; Muriu-Ng’ang’a, Felista
    Low and continuously deteriorating soil fertility coupled with frequent droughts and extended mid-season dry spells scenarios brought about by low and unreliable rainfalls have had a significant negative influence on agricultural productivity in most semi-arid regions of the world. The farmers' limited capacity to change their farming practices and adjust to the changing climatic circumstances further exacerbates these effects. Various in-field rainwater collection techniques, including Zai pits, have been promoted in recent years to assist farmers, particularly in dry and semi-arid locations, to harvest, store, and use rainfall for increased crop productivity. Zai pit is a form of dryland farming technique that involves the unitization of holes or troughs aimed at ensuring soil maintenance, soil erosion control and water preservation in agricultural fields. Additionally, combining effective soil fertility management strategies, such as integrated soil fertility management, with rainwater harvesting methods has the potential to further boost crop yields. Integrated soil fertility management involves the combined use of inorganic fertilizers and organic fertilizers such as cattle manure with the aim of improving soil fertility. Zai pit technology and integrated soil fertility management techniques have been utilized as climate smart agricultural approaches to reduce soil moisture stress and improve crop productivity in arid and semi-arid regions. This paper reviews previous research results on crop productivity as influenced by Zai pit technology and integrated soil fertility management techniques
