The Challenges Posed by Ipomoea kituensis and the Grass-Weed Interaction in a reseeded semi-arid environment in Kenya
Nyariki, Dickson M.; Mganga, K. Z.; Musimba, N.K.R.; Nyangito, M. M.; Mwang’ombe, A.W.; Ekaya, W. N.; Muiru, W. M. (2016)Rehabilitation of denuded patches using perennial grasses has been used extensively in semi-arid environments of Kenya. However, weeds continue to pose an enormous challenge to the success of many rehabilitation programmes. ... -
The choice of grass species to combat desertification in semi-arid Kenyan rangelands is greatly influenced by their forage value for livestock
Nyariki, Dickson M.; Mganga, K. Z.; Musimba, N. K. R.; Nyangito, M. M.; Mwang'ombe, A. W. (2013)Livestock production is the main source of livelihood in the arid and semi-arid lands in Africa. However, desertification characterized by vegetation degradation and soil erosion is a major threat to the sustainability of ... -
Competition indices of three perennial grasses used to rehabilitate degraded semi-arid rangelands in Kenya
Nyariki, Dickson M.; Mganga, K. Z.; Musimba, N. K. R. (2015)Rangeland degradation is one of the most serious environmental challenges in arid and semiarid environments in Africa. Grass reseeding technology, using indigenous perennial grass species has a great potential for restoring ... -
Determinants and rates of land degradation: Application of stationary time-series model to data from a semi-arid environment in Kenya
Mganga, K. Z.; Nyariki, Dickson M.; Musimba, N. K. R.; Amwata, Dorothy A. (Springer, 2018-02)The causes of land degradation in the African drylands have been shown to vary. Some researchers consider climate to be the major contributor to degradation, with anthropogenic factors playing a minor role. Others reverse ... -
Different land use types in the semi-arid rangelands of Kenya influence soil properties
Nyariki, Dickson M.; Mganga, K. Z.; Musimba, N. K. R.; Nyangito, M. M.; Ekaya, W. N.; Muiru, W. M.; Mwang’ombe, A. W. (2011)Rangelands in semi-arid Kenya have recently witnessed extensive land use changes. These changes can mainly be attributed to increased livestock populations and the response of the increased human population to both local ... -
Dry matter yields and hydrological properties of three perennial grasses of a semi-arid environment in east Africa
Nyariki, Dickson M.; Mganga, K. Z.; Musimba, N. K. R.; Nyangito, M. M.; Mwang'ombe, A.W.; Ekaya, W. N.; Clavel, D.; Francis, J.; Kaufmann, R. von; Verhagen, J.; Muiru, W. M. (2010)Enteropogon macrostachyus (Bush rye), Cenchrus ciliaris L. (African foxtail grass) and Eragrostis superba Peyr (Maasai love grass) are important perennial rangeland grasses in Kenya. They provide an important source of ... -
