This study addresses this critical gap by developing a reproducible geospatial framework that integrates high-resolution Earth Observation (EO) data with spatial econometrics to analyze the direct and spillover effects of infrastructure on socioeconomic outcomes under climatic stress. A Spatial Durbin Model (SDM) integrates two decades of satellite-derived vegetation health (NDVI), economic activity (nighttime lights), and gridded climate records across Tanzanian BRI corridors. The analysis reveals that the poverty-reducing effect of infrastructure is fundamentally contingent on local ecosystem stability, with a 14.2% reduction in poverty observed exclusively in zones with stable NDVI trends. This effect is amplified by significant spatial spillovers, which indirectly reduce poverty by 15% within a 50km radius. A key finding shows a 1°C temperature increase correlates with a $2.30 average per capita income decline, underscoring the climate vulnerability of development gains. Crucially, the findings demonstrate that a conventional development approach would require a 240% increase in investment to achieve outcomes equivalent to a climate-adapted design. This research establishes a transferable paradigm for leveraging open-source EO data within economic and development geography, providing robust evidence to guide resilient infrastructure policy and ensure sustainable development outcomes in a climate-stressed world.

development, yet their interaction with climate risks and ultimate impact on poverty resilience remains poorly understood at a granular, spatial level. This study addresses this critical gap by developing a reproducible geospatial framework that integrates high-resolution Earth Observation (EO) data with spatial econometrics to analyze the direct and spillover effects of infrastructure on socioeconomic outcomes under climatic stress. A Spatial Durbin Model (SDM) integrates two decades of satellite-derived vegetation health (NDVI), economic activity (nighttime lights), and gridded climate records across Tanzanian BRI corridors. The analysis reveals that the poverty-reducing effect of infrastructure is fundamentally contingent on local ecosystem stability, with a 14.2% reduction in poverty observed exclusively in zones with stable NDVI trends. This effect is amplified by significant spatial spillovers, which indirectly reduce poverty by 15% within a 50km radius. A key finding shows a 1°C temperature increase correlates with a $2.30 average per capita income decline, underscoring the climate vulnerability of development gains. Crucially, the findings demonstrate that a conventional development approach would require a 240% increase in investment to achieve outcomes equivalent to a climate-adapted design. This research establishes a transferable paradigm for leveraging open-source EO data within economic and development geography, providing robust evidence to guide resilient infrastructure policy and ensure sustainable development outcomes in a climate-stressed world.","manuscriptTitle":"Geospatial Assessment of Infrastructure and Climate Interactions on Poverty Resilience Along BRI Corridors in Tanzania","msid":"","msnumber":"","nonDraftVersions":[{"code":1,"date":"2025-10-15 08:08:01","doi":"10.21203/rs.3.rs-7744246/v1","editorialEvents":[{"type":"communityComments","content":0}],"status":"published","journal":{"display":true,"email":"[email protected]","identity":"researchsquare","isNatureJournal":false,"hasQc":true,"allowDirectSubmit":true,"externalIdentity":"","sideBox":"","snPcode":"","submissionUrl":"/submission","title":"Research Square","twitterHandle":"researchsquare","acdcEnabled":true,"dfaEnabled":false,"editorialSystem":"","reportingPortfolio":"","inReviewEnabled":false,"inReviewRevisionsEnabled":true}}],"origin":"","ownerIdentity":"da7af8bb-14a2-405a-81f9-b59b83547ea2","owner":[],"postedDate":"October 15th, 2025","published":true,"recentEditorialEvents":[],"rejectedJournal":[],"revision":"","amendment":"","status":"posted","subjectAreas":[],"tags":[],"updatedAt":"2026-02-17T20:23:17+00:00","versionOfRecord":[],"versionCreatedAt":"2025-10-15 08:08:01","video":"","vorDoi":"","vorDoiUrl":"","workflowStages":[]},"version":"v1","identity":"rs-7744246","journalConfig":"researchsquare"},"__N_SSP":true},"page":"/article/[identity]/[[...version]]","query":{"redirect":"/article/rs-7744246","identity":"rs-7744246","version":["v1"]},"buildId":"8U1c8b4HqxoKbykW_rLl7","isFallback":false,"isExperimentalCompile":false,"dynamicIds":[84888],"gssp":true,"scriptLoader":[]}
