The trade-offs

In its favourAgainst it
Kenya's agriculture sector size and productivity challenges create significant research relevance and development fundingAgricultural engineering field research requires extended presence at farms and rural research stations
Agritech is a growing investment area in Kenya attracting innovation funding and startup investmentAcademic agricultural engineering positions are concentrated at a small number of universities
Agricultural biosystems research connects to food security, a top global development funding priorityResearch funding for agricultural engineering, while present, is competitive and project-dependent

Common misconceptions

  • Engineering is only for men.

    Engineering increasingly welcomes women, with initiatives like Women in Engineering (WIE) chapters and institutional support promoting gender diversity.

  • Engineers only work on construction sites.

    Engineers work in design offices, research labs, manufacturing plants, energy companies, and tech firms, with many specialising in software, electronics, or biomedical engineering.

  • Agricultural engineering is just about tractors

    It covers irrigation systems, soil conservation, renewable energy for farms, and food processing.

  • Jobs are only in government or big farms

    Agritech startups, NGOs, and consulting firms hire agricultural engineers for innovative projects.
