1) Fanyajuu terrace is a traditional terrace system used in northern Nigeria for soil and water conservation in agriculture. It is constructed by digging a trench along the contour line, and piling up the excavated soil on the downhill side to form a ridge or bund. This bund acts as a barrier to prevent erosion and retain water on the sloping land. The terrace is then leveled and planted with crops.

2) A soil bund is a barrier made of soil that is constructed to prevent erosion, retain water, or manage flooding. It is usually built perpendicular to the slope of the land to slow down the flow of water and trap sediment. Soil bunds can be constructed by digging a trench and piling up the excavated soil to form a ridge, or by using machinery to shape and compact the soil into a barrier.

3) A stone-faced soil bund is a soil bund that is reinforced with a facing of rocks or stones. This type of bund provides additional stability and erosion resistance. The stones are placed on the outer surface of the bund to prevent it from being washed away by flowing water. Stone-faced soil bunds are commonly used in areas with high rainfall or strong currents.

4) A trench is a narrow excavation in the ground that is typically deeper than it is wide. Trenches can be used for a variety of purposes, such as drainage, irrigation, or burial. An eyebrow basin is a specific type of trench that is designed to collect and store water. It is constructed by digging a shallow basin with raised edges that resemble eyebrows.

5) The function and advantages of all the above-mentioned structures are to improve soil and water management in agriculture. Fanyajuu terraces, soil bunds, stone-faced soil bunds, trenches, and eyebrow basins all help to prevent erosion, retain water, and reduce runoff. These structures can increase crop productivity, reduce soil degradation, and improve overall land sustainability. By retaining water on the land and slowing down the flow of water, these structures can also help to mitigate the impacts of drought and flooding. Overall, these structures play a crucial role in sustainable agriculture practices and environmental conservation.
