Forest and landscape restoration measures could address landscape degradation, increase ecosystem services, and improve livelihoods. However, mapping potential areas for forest and landscape restoration measures and identifying enabling and constraining factors is crucial for effective implementation. This study was conducted in the western catchment of Lake Ziway, Central Rift Valley, Ethiopia, to identify potential forest and landscape restoration options, map potential areas, assess the benefits and cost of options, and investigate success and failure factors for implementing interventions. The study adopted the Restoration Opportunities Assessment Methodology (ROAM), which enables selecting and mapping forest and landscape restoration options. Data were collected using field surveys, key informant interviews, focus group discussion and literature reviews. We also employed GIS and remote sensing methods to characterize the long-term land use and land-cover dynamics and changes in the status of land degradation. Cost–benefit analysis was conducted to assess the economic viability of identified restoration options. The results suggested that over the last 20 years (2002 to 2022), the western catchment of Lake Ziway experienced severe forest and landscape degradation due to anthropogenic and climatic factors, resulting in multiple environmental and socioeconomic consequences. This study identified seven context-specific forest and landscape restoration measures to address the problem. They vary in cost, trajectory and specific economic and social outcomes. Most options were economically viable with additional environmental and social benefits. For example, the benefit of carbon sequestration for home garden agroforestry was estimated at USD 27,032.5 ha-1 over 20 years. It was also found that a considerable portion of the catchment area was potentially suitable for agroforestry practices (40%), particularly for scattered trees on farmlands. However, the potential areas suitable for full afforestation or reforestation and tree buffers are smaller (6%). Integrating multiple forest and landscape restoration measures in the catchment could maximize the environmental and socioeconomic outcomes. Opportunities to effectively implement and scale up the identified forest and landscape restoration options include the availability of adequate active labor, the diverse benefits of measures, and the existence of supporting policies and strategies, multiple potential financing mechanisms and active development of governmental and non-governmental organizations. However, the absence of guidelines for implementing legal issues, weak coordination among responsible institutions, and inadequate finance and incentives have been identified as major constraints to scale up forest and landscape restoration measures. The findings of this study may serve as a guide for the planning, design and implementation of restoration measures in the study catchment and similar future projects in other catchments.

In Ethiopia, forest landscapes and freshwater ecosystems are important for biodiversity conservation, providing a range of benefits and services that are fundamental to the environment, society and economy. However, human activities such as agricultural expansion, land-use and land-cover changes, together with climate change have impacted these ecosystems and the services they provide. Despite these challenges, 4 years of field studies (2019-2023) of the SaWeL (Safeguarding Sahelian Wetlands for Food Security) project in the western catchment of Lake Ziway, one of the freshwater ecosystems in Ethiopia, demonstrates various opportunities that exist to better manage the forest landscapes and freshwater ecosystems. This brief provides recommendations on how to improve the planning, design and implementation of landscape management practices, and how to use the Ecologically Sustainable Agricultural Water Management (ESAWM) framework. The brief is also intended to help local-level practitioners (government, Nongovernmental organizations [NGOs], and private sectors) realize existing opportunities for sustainable landscape management.
