Resources for evaluating the ecological outcomes of ecosystem restoration projects are often limited, especially within government-funded programs. In order to rapidly assess the ecological outcomes of wetland restoration, an improved approach has been developed, which was applied in the assessment of the ecological outcomes at nine restoration sites of South Africa's Working for Wetlands program. The sites encompass a diversity of restoration problems and land use contexts. The approach begins by distinguishing hydrogeomorphic (HGM) units, for which ecological condition is assessed and reported for hydrology, geomorphology, and vegetation pre-and post-restoration. These three components are closely linked but, as demonstrated at some of the sites, may respond differentially to restoration interventions. For most HGM units, overall ecological condition was improved by between 10 and 30%, with the greatest contribution of restoration generally being to the hydrology component. Having determined the integrity and costs of the interventions, cost-effectiveness is then reported in South African Rands per hectare equivalent restored, which was found to vary by more than an order of magnitude across the HGM units assessed. Cost-effectiveness must be interpreted in the light of the long-term integrity of the interventions, the site's landscape context, and the contribution of restoration to ecosystem services provision. Some sites may be considerably less cost-effective than others, but the cost may nonetheless be justified if the sites make key contributions to ecosystem services provision. The study was conducted in the context of a formative evaluation and the findings are envisaged to improve wetland restoration practice. Implications for Practice• Even when faced with very limited resources for assessment, the contribution of wetland restoration to ecological condition can be tracked using an approach for scoring the hydrology, geomorphology, and vegetation components of ecological condition, which is scientifically defensible but not onerous in terms of data and expertise. • Expressed as costs per hectare equivalent of ecological condition restored, useful comparisons can be made across different restoration sites. • However, results must be interpreted in the light of the site's landscape context, type of restoration problems, and the long-term integrity of the restoration interventions. • The approach has potential to improve future wetland restoration practice, including planning, as well as monitoring and evaluation in relation to specific restoration objectives and ecological condition targets.

“…Green vegetation can increase atmospheric humidity and lower temperatures by transpiration. These two ecological processes together contribute to controlling temperature increases in nearby areas, thus playing a vital role in mitigating and adapting to the impacts of urban heatwaves and UHI [43,44]. Research by Bounoua et al showed that the temperature of impermeable surfaces in summer is, on average, 2 • C higher than permeable surfaces [45].…”

Cities worldwide are facing varying degrees of ongoing threats closely tied to climate change. Research is emerging that addresses climate risks as a pressing issue, especially for vulnerable cities in the Global South; however, there is a significant lack of systematic and application-oriented research on ecosystem-based adaptation to urban climate change. This study uses Shenyang in Northeast China as a case study, employing multisource data and integrated methods to examine and depict the dynamics of urban ecosystem-based adaptation to climate change amid rapid urbanization. The results indicate a decline in capacity for climate change adaptation during the study period. A framework for mainstreaming ecosystem-based adaptation is proposed, identifying specific strategies for climate change mitigation and adaptation in urban policy and planning processes in Shenyang. It also has significance for other cities to draw lessons from. By linking urban ecosystem dynamics, the capacity for urban climate adaptation, and sustainable urban governance, this study bridges the gap between research and practice in urban climate change adaptation, and expands the contribution of geography-based interdisciplinary integration to urban resilience. More practically, it provides references for Shenyang in adapting to climate change and transitioning to sustainable development.
