The Management of On-Farm Soil Erosion Using Fanya Juu and Fanya Chini Terracing: A Manual for Farmers provides practical, step-by-step guidance to help farmers prevent and manage soil erosion on sloping land. It begins by explaining what soil erosion is, how it leads to nutrient loss and reduced productivity, and the economic impact of losing topsoil—expressed in terms of fertiliser value and Land Economic Value (LEV). The manual highlights the long-term consequences of erosion, including declining yields, climate change effects, and reduced farm resilience. It then outlines simple soil and water conservation practices, with a strong focus on terracing as an effective method for reducing runoff and soil loss. Detailed technical sections guide farmers on measuring farm slope, calculating vertical and horizontal intervals, determining terrace spacing, and constructing both Fanya Juu and Fanya Chini terraces using locally available tools. The final section covers terrace maintenance, including desiltation and embankment reinforcement, ensuring terraces remain stable and productive over time. Overall, the manual equips farmers with practical knowledge to protect their soil, improve productivity, and sustain their land for future generations.
