Dr. Francis Gichuki Brief Bio

Dr. Francis Gichuki is an agricultural and irrigation engineer. He obtained his PhD at Utah State University, USA in 1988. He has taught and researched on soil and water engineering (irrigation, drainage, water harvesting and soil and water conservation), river basin management, modelling, and GIS at the University of Nairobi from since 1978. He is currently the leader of Integrated Basin Water Management Systems theme of the Challenge Programme on Water and Food (www.waterforfood.org).

Gichuki, FN.  2000.  Makueni district profile: soil management and conservation, 1989-1998. AbstractWebsite

The investments in soil conservation made by farmers in Makueni District, Kenya over the period 1950-1998, and the policy and institutional framework under which the investments were made are explored. An assessment of the scale and impact of these measures is presented. In general, very few signs of erosion were observed, so the area is considered to have low erosion status. Soil and water conservation measures include the use of crop residues in trash lines, contour ridging, grass strips, fanya juu terraces and cut-off drains. Crop residue management and tillage are the main practices used to facilitate in situ moisture conservation. Most farmers practise contour ridging. Physical soil conservation measures are used to complement cultural practices that conserve rainwater in situ by trapping and preventing further runoff. A key constraint to the expansion of soil and water conservation measures by households is the shortage of hired and family labour. Grazing land has received very little investment because there farmers perceive a low return. In Makueni District farmers have been able to make long-term investments in soil conservation partly because their land tenure was secure. Training and extension in soil and water conservation has been a major external input.

Allen, RG, Gichuki FN, Rosenzweig C.  1991.  CO2‐Induced Climatic Changes and Irrigation‐Water Requirements. AbstractWebsite

Effects of CO2‐induced climatic changes on irrigation‐water requirements (IR) in the Great Plains region were evaluated using results of global atmospheric‐circulation models with a water balance‐IR model. Increases were predicted for evapotranspiration Et due to predicted increases in air temperature, solar radiation, and wind speed under doubled concentrations of atmospheric carbon dioxide (2×CO2). Predicted increases in humidity under the 2×CO2 scenarios and shifting of crop life cycles to months with lower levels of solar radiation moderated predicted increases in Et. Increases in irrigation requirements were caused primarily by increases in evaporative demands and changes in precipitation patterns. Increases in net seasonal IR for alfalfa were larger due to predicted increases in length of frost‐free growing seasons and higher evaporative demands as compared to winter wheat and corn. Decreases or only modest increases in seasonal irrigation requirements were projected under 2×CO2 scenarios for com and winter wheat due to reductions in length of crop life cycles and projected increases in bulk stomatal resistances.
