**4.3 Results of successful land husbandry interventions**

#### *4.3.1 Technical achievements*

Successful results covered more than 19,500 ha with comprehensive land husbandry technologies across the country out of which over 3,400 ha were located on marginal lands. The lands were made productive after land husbandry works. For this particular study cases, bench terraces were established at 2673 (gross area of 4284 ha) and 3212 ha (gross area of 4800 ha) of lands for Karongi 12–13 and Nyanza 23, respectively (**Figures 13** and **14**). Technologies effectively reduced erosion for about 98% of the total soil losses. Other land uses such as forest, settlements, water reservoirs and papyrus were also rehabilitated on about 901 ha.

Besides the use of land husbandry technologies, the sites were restored in terms of soil fertility replenishment through the use of lime (5 t ha−1), compost/manure

(10 t ha−1) and mineral fertilizer (DAP and Urea) inputs accompanied with irrigation in the command area for optimally increasing productivity. Farmers are growing food crops like beans, maize, cassava, sweet potato, sorghum, banana, vegetables (chili, tomato, eggplant, onion, sweet pepper) and various fruit species (watermelon, tree tomato, avocado, macadamia, etc). However, the productivity did not reach the expected optimal yield.
