ABSTRACT Despite increased understanding and adoption of nature‐based solutions (NBSs) within urban coastal areas, large‐scale NBS for fluvial flood mitigation remain challenging to study implement. A stronger evidence base is needed identify critical research gaps best inform the design deployment on watershed scale. We synthesize performance co‐benefits based a systematic review 131 peer‐reviewed papers worldwide, developing an Ecosystem Focus Type (EFT) compare across NBS. While we find that can mitigate floods all EFTs, our also highlights inconsistencies in measurement methods, dearth empirical case studies, large variability reported values limit generalization comparison Co‐benefits are numerous, but few quantified, methods vary with regard specific Social benefits NBS, including communities most need support, infrequently part these studies. There clear develop common standards guidance which measures key consider monitor co‐benefits. The success will depend practice guided by transdisciplinary systems thinking approaches deliver evidence‐based, community‐driven outcomes.

Empirical evidence suggests that there has been an increasing negative impact of climate change on the production arable crops in Sub-Saharan Africa (SSA), particularly Nigeria. Farmers must critically evaluate and adjust to challenges presented by order build resilience. Global, national, local adaptation efforts have progressed through international debate, national programs, community-based initiatives. Adaptation seen as a vital component all-encompassing, long-term global response change, protecting farmers, livelihoods, ecosystems. However, even though are several studies regarding factors influencing farmers' decisions adapt change. There is still need for present study deeper understanding new knowledge about discourse. Therefore, it critical understand influence guarantee right policies put place support their efforts. In light this, our examined crop adaptation. We made use cross-sectional data from 144 farmers who were chosen farming villages Southeast Nigeria using standardized questionnaire. To choose farmed crops, we used purposive multistage sampling techniques. The approach was employed identify regions with high concentration producing crops. Multinomial logit regression descriptive statistics analyze gathered data. Our found variety strategies manage risks, including migration (Y1), changing dates planting harvesting (Y2), altering tillage operations (Y3), intercropping (Y4), rotation (Y5), mixed cropping (Y6), agroforestry practices (Y7), introducing well-acclimated varieties (Y8), mulching (Y9), livelihood diversification (Y10). also demonstrates following influenced area: sex (X2), age (X1), education (X3), experience (X4), household size (X5), farm income (X6), participation cooperative (X7), extension contact (X8). cost inadequate strategies, among others, barriers facing area. recommended should take advantage various societies so jointly pool productive resources adequately Ultimately, important government strengthen agricultural service system provide up-to-date modern information, training, capacity building improved yield, income, standard living

Abstract A community-driven effort in Cedar Key, Florida, USA, resulted the construction of three living shoreline retrofits intended to bolster failing coastal infrastructure and restore habitat functions Daughtry Bayou. multi-year monitoring program tracked changes elevation vegetation communities across entire profile from lower-intertidal upland/transitional zones measured wave attenuation during typical extreme (hurricane) conditions. Overall, these served soften more than 30% bayou’s shoreline, dramatically reducing extent armored direct contact with tidal influence. The vegetated area has increased at all sites, despite sediment export higher driven largely by repeated impacts hurricanes tropical storms. These shorelines reduced energy 33 79% conditions up 28% hurricane conditions, consistently outperforming shorelines, even an event (Hurricane Idalia). Our efforts were sufficient capture project trajectories assess performance relative goals, but our had limitations that could have been overcome additional resources focus on capturing spillover effects. retrofit projects assessed here persisted through shown signs recovery after multiple storms hurricanes, while providing important reduction services. Thus, continue be a cost-effective management strategy short term for this area. However, analyses suggest persistence threatened combination sea-level rise (by 2040), upland armoring, increasing risk intense systems. Therefore, future interventions should carefully consider threats conjunction enhancement goals.
