Tree growth and water-use in hyper-arid Acacia occurs during the hottest and driest season
(Springer-Verlag GmbH Germany, 2018)
Drought-induced tree mortality has been recently increasing and is expected to increase further under warming climate. Conversely, tree species that survive under arid conditions might provide vital information on successful ...
Head teacher’s supervision of curriculum implementation: implications on provision of quality Secondary education in Kenya
(society for science and education, 2016)
This study sought to find out how the head teachers’ supervision of curriculum implementation influences provision of quality education in Kisumu East Sub-County Secondary schools, Kenya. The study population consisted of ...
Effect of grazing and canopy on Mediterranean ecosystem functioning: Carbon dioxide exchange and the dynamics of carbon and nutrient pools
(EGU General Assembly, 2010)
Mediterranean ecosystems occupy less than 5 % of the Earth's surface, yet they contain about 20 % of the world's flora, including important components in grasslands. In this study, important ecosystem functions (CO2 exchange, ...
Land use changes across river Nanyuki catchment, Kenya using CLASlite and envi
(International Journal of Advances in Engineering & Technology, 2014)
Land use change is a significant factor in environmental conservation and climate change which may be positive or negative depending on how it occurs. The study aimed at examining the land use changes that took place across ...
Farmers' preferences for methods of receiving information on new or innovative farming practices
(Journal of Agricultural Education, 1989)
Use of downscaled tropical rainfall measuring mission data for meteorological drought monitoring: case study of Narumoru catchment
(International Journal of Advances in Engineering & Technology, 2014)
Remotely sensed satellite rainfall data has gained popularity in the recent past, been especially attractive to ungauged catchments or poorly gauged catchments. Tropical Rainfall Measuring Mission (TRMM) data is considered ...
Patterns of CO2 exchange and productivity of the herbaceous vegetation and trees in a humid savanna in western Kenya
(Springer Science+Business Media Dordrecht, 2015)
Factors governing the dynamics between woody and herbaceous vegetation in the savanna are of ecological interest since they determine ecosystem productivity and stability. Field measurements were conducted in a humid savanna ...
Nutritional and developmental influences on components of rice crop light use efficiency
(Elsevier, 2016)
Light use efficiency (LUE) plays a vital role in determination of crop biomass and yield. Important components of LUE, i.e. canopy structure, nitrogen distribution, photosynthetic capacity and CO2 diffusion conductance ...
The Afro-alpine dwarf shrub Helichrysum citrispinum favours understorey plants through microclimate amelioration
(Taylor & Francis, 2015)
Background: Positive plant–plant interactions similar to specialised plant growth forms are potential strategies to overcome the environmental harshness of Afro-alpine ecosystems. However, knowledge about plant–plant ...
Soil water availability and capacity of nitrogen accumulation influence variations of intrinsic water use efficiency in rice
(Elsevier, 2016)
Leaf intrinsic water use efficiency (WUEi) coupling maximum assimilation rate (Amax) and transpirable water lost via stomatal conductance (gsc) has been gaining increasing concern in sustainable crop production. Factors ...
