Using panel data collected between 2014 and 2015, this study seeks to add to the growing body of literature on the determinants of irrigated agriculture adoption, its effects on child nutrition, and the potential pathways through which irrigation can affect child nutrition outcomes. The results from the inverse probability weighted regression adjustment<span> (IPWRA) estimator suggest that children living in irrigating households have, on average, 0.23 standard deviations of weight-for-age and 0.27 standard deviations of weight-for-height higher than their counterparts; with males and under-five children gaining substantial improvements. Disaggregating irrigation by types, the results indicate that households planting on riverbeds or riverbanks had improved child nutrition.

By exploring water input supply unawareness via alternative states of nature we may identify tipping points where current technology fails, resulting in irreversible losses of private and public capital tied to water inputs. We conclude by discussing the value of quantifying minimum-input requirements and identifying critical tipping-point outcomes in water systems, increased benefits/risks from transformed landscapes chasing higher economic returns, and the need for adaptive public arrangements in response.

However, building-level adaptation measures such as floodproofing or building elevation are often evaluated at aggregated spatial scales, which may result in sub-optimal investment decisions. In this paper, we develop a flood risk model and combine it with a micro-scale CBA at the building level to obtain an optimal mix of adaptation measures per area. We apply this approach to Venice Beach in Los Angeles and Naples in Long Beach. We subsequently compare our results with the conventional, spatially aggregated area-based CBA approach. Our findings show that a mix of 35%–45% dry-floodproofing measures and 55%–65% building elevation measures is optimal. Elevation works best in areas with high inundation depths, while dry-floodproofing is preferable in areas with shallow inundation depths. The optimal mix of measures derived from our micro-scale approach results in an economic efficiency up to 85% higher than that yielded by the commonly applied spatially aggregated approach. We therefore recommend that economic evaluations of building-level adaptation measures are conducted at the smallest possible scale, or that CBAs are performed on disaggregated areas based on inundation depth.</p></div>","PeriodicalId":48644,"journal":{"name":"Water Resources and Economics","volume":"32 ","pages":"Article 100147"},"PeriodicalIF":2.2,"publicationDate":"2020-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.wre.2019.100147","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47324427","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
