IHE Delft Alumni & Partners Online Seminar by Mr. Benson Mutuma Karimba (new alumnus)

'Dynamics of private smallholder irrigation using sand river aquifers in semi-arid lands'

  • 15 Sep 2020
  • 11:45 - 12:45

IHE Delft Alumni & Partners Online Seminars are designed as a means of providing lifelong learning to the Institute Alumni community and Partners. Since the topics will be of interest to a broader audience, they are open to all interested persons. The Online Seminars are like interactive lectures transmitted over the web, with a duration of one hour including time for discussion. The seminar is organized in collaboration with the WaterChannel, IHE Delft partner.


In many countries of Sub-Saharan Africa, smallholders are increasingly participating in irrigation development using their private capital with minimal government or donor support. This kind of farmer-led irrigation development is crucial in achieving food security and alleviating poverty for millions of smallholders who depend on agriculture for their livelihoods. An important driver for farmers to invest in irrigation is the availability of water and seasonal rivers commonly found in semi-arid areas contain shallow alluvial aquifers that have the potential of supporting smallholder irrigation.

However, private smallholder irrigation takes place in informal settings and the derived benefits, challenges and failures of farmers which shape their development trajectories are not well understood.  Its continued and unchecked spread also raises concerns about sustainable management of land and water resources.

The objective of this research was to therefore assess the characteristics of private smallholder development along a seasonal sand river in Southern Kenya including the drivers, challenges and trajectories of farmers’ development over time. The webinar will present the methodology and findings of the research.  


Mr. Benson Mutuma Karimba is a graduate engineer and researcher from Kenya. He recently graduated from IHE Delft with an MSc specialization in Land and Water Development for Food Security and won the WSE thesis Award 2020 under the theme of sustainability. Benson has an BSc in Soil, Water and Environmental Engineering from Jomo Kenyatta University of Agriculture and Technology and currently works in the Biosystems Engineering Department of Meru University of Science and Technology. He has also worked as a sales engineer in the private sector for 4 years dealing with the supply and installation of water pumps, drip irrigation systems and solar powered equipment. His research interest is in irrigation development and particularly strengthening of adaptability and resilience of smallholder farming systems.
