“…The land use alteration has also impacted the ecohydrological processes (Ajanaw, 2021; Simeneh et al, 2023b; Sisay, 2014), the quality and quantity of water (Helnata, 2019; Taye, 2009), and the welfare of downstream water users (Yilikal et al, 2019). Furthermore, it greatly increased soil erosion, resulting in a significant sediment load to water reservoirs (Gebreegziabher et al, 2021; Simeneh et al, 2022), thus considerably reducing the capacity of water reservoirs (AAWSA, 2011).…”

The rapid deterioration of the upper Akaki catchment natural environment has led to an increasing impact not only on the watershed ecosystem but also livelihood and general well‐being of the local community. As a result, the water supply is becoming a problem for Addis Ababa and its surrounding residents. This may lead to a greater willingness to pay and cooperate in initiatives to protect the watersheds. Therefore, a market‐based instrument and participatory arrangements are critical for resolving socio‐ecological problems. Therefore, this research aimed to demonstrate a need for an incentive‐based watershed conservation approach that can be used to support nature conservation through long‐term financial investments in the central watersheds and elsewhere. To support the market‐based intervention sealable ecosystem services and cost‐benefit analysis, as well as relevant stakeholders, institutions, and legal frameworks were assessed. The premise factors for designing market‐based approaches to halt biodiversity loss and reversing ecological processes are discussed. A domestic water tariff increase of ETB 1 per m3 (US$ 0.08) could raise approximately US$ 3.24 million annually for watershed management, which could compensate smallholder farmers' annual opportunity costs for crop and livestock forage loss. Furthermore, the practice could help to abate biodiversity loss and improve the local economy and accelerate the implementation of global biodiversity targets.
