Item Cactus invasion: A Threat to Biodiversity and Food Security(University of Nairobi, 2020-01) Githae, EuniceThis policy brief: The prickly pear cactus has a negative impact on food security, biodiversity and human well-being. The cactus invades mostly arid and semi-arid lands (ASALs), which form more than 80% of Kenya's landmass. Livestock keeping is the main socio-economic activity in these areas. The plant is hardly appreciated due to the presence of spines and glochids (small spines on fruits) that cause injuries to people and livestock. In Narok County, the cactus invasion has increased rapidly over the last five years and has displaced people and pastures. The plant has been present in Laikipia County for more than ten years and has invaded grazing land, contributing to the death of livestock and wildlife.Item Enhancing Sustainability in African Catfish Seed Supply for Improved Production in Kenya(University of Nairobi, 2020-01) Barasa, JamesIdentification and isolation of high-quality catfish brood stock for use at hatcheries in artificial propagation in combination with improved husbandry for resultant fry could be a suitable strategy to increase the availability of farm-raised catfish seeds to support expanded aquaculture in Kenya. To maintain the quality of such brood stock, nuclei hatcheries should be developed, to manage this stock. Such hatcheries will be charged with artificial propagation of catfish larvae for sale to farmers, who should consistently maintain best management practices on their farms.
