Land Use and Land Cover Dynamics in the Weito River Catchment

A new study published in the Discover Sustainability journal has shed light on the spatio-temporal dynamics of land use and land cover in the Weito River Catchment in Ethiopia. The research, conducted by a team from the Addis Ababa Science and Technology University, used remote sensing and CA Markov modeling approaches to classify satellite images from 1986, 2003, and 2023. The study's findings indicate a significant expansion of agricultural land, accompanied by a decline in forest, grassland, and shrubland areas.

Key Takeaways:

• The study assessed the spatio-temporal dynamics of land use and land cover in the Weito River Catchment by classifying satellite images from 1986, 2003, and 2023 using maximum likelihood classification algorithm.
• The research predicted that agriculture would expand by 13% by 2043, while forest, grassland, and shrubland areas would decline by 8, 79, and 21%, respectively.
• The main drivers behind land use and land cover dynamics in the catchment were identified as agricultural expansion, population growth, and charcoal production.
• The study's findings have implications for water resource management, local livelihoods, ecological well-being, climate adaptation strategies, and land policy interventions.
• The researchers used remote sensing and CA Markov modeling approaches to classify the catchment area into six land use and land cover categories: Agriculture, Bareland, Forest, Grassland, Settlement, and Shrubland.

Statistics:

• The accuracy assessments using the Kappa Index revealed classification accuracies of 89, 91, and 94% for the years 1986, 2003, and 2023, respectively.
• The expansion of agricultural land between 1986 and 2023 was 134%, while forest, grassland, and shrubland areas declined by 36, 84, and 29%, respectively.
• By 2043, agriculture is expected to cover 13% more area, while forest, grassland, and shrubland areas are expected to decline by 8, 79, and 21%, respectively.
