Influence of social-economic factors, gender and the Fish Farming Enterprise and Productivity Project on fish farming practices in Kenya

Fish contribute 7 billion shillings to the Kenyan economy annually and fish processing, value addition and marketing provide excellent opportunities for the development of Public-Private partnerships. Government intervention in fish farming in Kenya started in 1921 when the colonial government introduced trout, common carp and black bass into the country. Despite many government initiatives, fish farming has not been fully integrated with other farming systems and its contribution to the national economy is small.

A Review of Some Methods Used in Determining Actual Evapotranspiration in East Africa

A brief review of some of the methods used in East Africa for determining actual evapotranspiration/evaporation is presented. The methods reviewed include: empirical methods, atmospheric water balance method, and the energy budget method

Department of land resource management & agricultural technology annual report 2012/2013

The Department of Land Resource Management and Agricultural Technology (LARMAT) through training, research and community service, aims at enhancing sustainable natural resource management and development of technologies suitable for sustainable livelihoods, and informing policy. The department offers b oth undergraduate and postgraduate programmes in soil, water, range, agroforestry and environmental management. The department also offers consultancy and advisory services in soil survey, soil fertility and water management, land use planning, and bio - fer tilizer producti on among others.

Application of Geographic Information Systems in irrigation development case study lower kuja irrigation development project, Nyatike district, Kenya

Assessing available land and water resources for irrigation is important for planning their use. The study area, Lower Kuja, Nyatike District like most parts of Kenya lacks soil information at sufficient detail for proper land use planning. The study involved quantitative investigations of soil properties, inventory of land use systems and an assessment of the potential of the study area for paddy rice cultivation land use requirements. This study was conducted to estimate paddy rice irrigation potential in Lower Kuja using the GIS technique.

Assessment of farmers’ perceptions of health risks of untreated wastewater used for crop production in Maili Saba, Nairobi - A gendered perspective.

The use of untreated wastewater for crop production poses serious health risks to the farmers. The greatest risk is from helminth infections and as a result of repeated exposure, the farmers are likely to build up high infection doses. The purpose of the research was to generate gender disaggregated data and document health risk perceptions of farmers exposed to untreated wastewater used for crop production in Maili Saba, Nairobi.

Effects of crop residue management practices on soil moisture conservation and validation of cropwat model for predicting water use requirements for tomato crop in Kabete, Kenya

The frequent drought due to climatic change poses a major challenge to food security and incomes to the rural farming communities. Therefore, there is need to develop technologies that can increase crop yields with the low available water through improved water use efficiencies that are sustainable without posing land and environmental degradation. Dependence on rainfed agriculture in Kenya leads to very low yields especially in years when rains are insufficient to support normal growing period for most crops.

Scheduling for supplemental irrigation in Mwala, Machakos district

This study focuses on supplemental irrigation in Mwala area of Machakos District. 1 he area is classified as Arid and Semi-Arid land (ASAL) where rainfall is unreliable in both time and space. This has often led to crop failure that results to famine in the area. Rainfall analysis was done to determine onset, cessation, length of the rainy season and occurrence of in-season drought spells. Early onset resulted to more seasons’ rainfall.

Factors influencing farmers' participation in operation and maintenance of smallholder irrigation projects in Gichugu Division, Kirinyaga East District, Kenya

Smallholder irrigation .development in Kenya has gained momentum over the last decade due to support from both the government and development partners. There has also been growing interest in this sector on the part of farmers due to sensitization by stakeholders on the need for intensification of agricultural production. However the major challenge has always been poor performance due to inadequate farmer participation, low level of government support services, weak Irrigation Water Users Associations (IWUAs) and inability of the beneficiaries to raise required funds.

Crop yield and water use in smallholder irrigated Agriculture: a case study of Nyanyadzi (Zimbabwe) and Matanya (Kenya) irrigation schemes

The performance of most smallholder irrigation schemes has been disappointingly low. This study aims at establishing the causes of low crop yield in Nyanyadzi and Matanya irrigation schemes and to identify possible interventions. Nyanyadzi irrigation scheme was developed in 1938. Maize crop yields are between 0.86-2.5 t/ha compared to a potential of 4-5 tons/ha. Matanya irrigation scheme was developed in 1940 and its crop yields for maize are between 0.5-1 t/ha compared with a potential of 5-6 t/ha.

The effect of irrigation management on crop water requirement and crop water productivity of tomato and sweet corn in Kibwezi, Kenya

Research on crop water requirement and productivity is important to reduce agricultural water use in arid and semiarid areas (ASAL), where water is a limited resource. A study was conducted to determine crop water requirement and evaluate crop water productivity of tomato (Lycopersicon esculentum L. var. M82) and sweet com (Zea mays L. var. Renat) under drip and sprinkler irrigation systems, respectively, in Kibwezi.
