Deforestation: Converting natural areas into terraced farmland often requires deforestation. This can reduce habitat for forest-dwelling species, fragment populations, and disrupt food chains.
Habitat Fragmentation: Terracing can create physical barriers that divide natural habitats, making it more difficult for animals to move, find food, and reproduce. Fragmented habitats can also lead to increased competition between species for limited resources.
Increased Sedimentation: Terracing can lead to increased soil erosion, which can result in sedimentation of waterways. This can affect aquatic habitats, smothering fish eggs, clogging gills, and reducing water quality for aquatic species.
Changes in Water Availability: Terracing can alter water flow patterns, affecting the availability of water sources for wildlife. This can be particularly detrimental during dry seasons when water is scarce.
Loss of Biodiversity: The combination of habitat loss, fragmentation, and changes in water availability can contribute to a loss of biodiversity in areas where terrace farming is practiced. This can disrupt ecosystem dynamics and reduce the resilience of natural communities to environmental changes.
