While existing scholarship has documented flood impacts and theorized governance deficits, few studies have traced the precise causal pathways through which institutional pathologies—fragmentation, spatial mismatch, and perverse incentives—produce recurrent disaster outcomes. This study addresses this gap by diagnosing the systemic governance failures that amplified the 2025 floods. Employing a Diagnostic Policy Analysis Framework for Recurrent Disasters through mixed-methods analysis of 27 official documents captured during the acute crisis phase, we demonstrate that the flood’s magnitude resulted from three interconnected governance failures: (1) institutional fragmentation that crippled coordination and response; (2) spatial mismatch between uniform national policies and Pakistan’s diverse hydro‑geographical regimes; and (3) perverse incentives that reward visible post‑disaster relief over proactive prevention. Our findings trace these failures to specific institutional mechanisms: irregularities in infrastructure contracting documented in audit reports, political interference in relief distribution, and the systematic disempowerment of district‑level disaster authorities. We further identify three transferable diagnostic pathways—fragmentation, spatial mismatch, and perverse incentives—that offer an analytical template for analyzing recurrent disasters in other complex governance contexts. The study concludes that building resilience requires confronting these specific institutional pathologies. For Pakistan, this means empowering district disaster authorities with mandated minimum budgets and evacuation authority under the NDMA Act, enforcing existing floodplain zoning regulations against politically connected developers, and restructuring disaster financing to pre‑position funds for pre‑emptive action triggered by meteorological forecasts.</p></div>","PeriodicalId":543,"journal":{"name":"Environmental Management","volume":"76 7","pages":""},"PeriodicalIF":3.4,"publicationDate":"2026-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148443686","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study delivers the first assessment and projections of spatial habitat quality in the basin and its KBAs from 2017 to 2031 by integrating the InVEST habitat assessment model with land-use change predictions from the MOLUSCE-QGIS model to understand habitat quality status, the impacts of land-use dynamics, vulnerability hotspots, drivers of change, and needs to be addressed in the basin’s conservation. The results reveal widespread habitat vulnerability, particularly impacting rangelands, which are projected to decline by 9.4 percentage points. Basin-wide habitat quality is expected to decrease from 93.5 to 88%, with KBAs experiencing a decline from 95.1 to 90.1%. Specific KBAs, such as Virunga, Kibira, Rusizi, and Itombwe National Parks, show substantial declines, with 35 to 50% of their habitats in vulnerable conditions. Other KBAs, including Nyungwe, Kahuzi-Biega, and Gishwati-Mukura National Parks, are expected to face additional threats, particularly from roads and built-up infrastructure. Threat extent and intensity analysis revealed complementary threats with diverse impacts: deforestation, mining, and agriculture dominated by spatial coverage (78.5% of total impact; deforestation alone >40%), while mining and urbanization showed the strongest per-unit impact (β = −8.20 and −5.48; <i>p</i> < 0.001), with odds ratios near zero (OR = 0.0003 and 0.004), indicating that the presence of these drivers almost entirely eliminates the probability of suitable habitat quality at their operational sites.

To resolve this tension in the Sudanese savannah of North Cameroon, systematic sampling of 4,166 individuals across 68 species quantified avian responses to landscape conversion into Mixed Rural Habitats, Rice Paddies, and Annual Crop Fields. Although aggregate species richness and abundance remained invariant across these land-use types, pairwise comparisons confirmed that each habitat supports a distinct avian signature, driving systematic community turnover rather than taxonomic attrition. Community identity partitioned decisively by land-use, with Annual Crop Fields supporting 39.7% of unique species, Rice Paddies at 26.5%, and Mixed Rural Habitats at 7.4%. Furthermore, 13.23% of recorded species were exclusively restricted to these agricultural systems, establishing land-use type as a statistically significant predictor of community assembly and confirming that each habitat contributes a unique structural component to the regional species pool. Functional organization mirrored this targeted reconfiguration; while most feeding guilds exhibited resilience to modification, Aquatic predator and Omnivore abundances proved highly sensitive to land-use variation, identifying these specific guilds as critical functional sentinels of anthropogenic disturbance. Ultimately, these dynamics fundamentally reframe the conservation value of agricultural savannahs, shifting the primary metric of success from gross species counts to the preservation of compositional turnover and functional integrity. The persistence of these diverse assemblages remains strictly contingent upon the structural complexity of the land-use mosaic rather than the mere localized absence of human activity. Consequently, effective conservation in the Sudano-Sahelian biome necessitates management frameworks that transcend simple habitat preservation to actively integrate native vegetation within productive agricultural systems, ensuring that unchecked agricultural expansion does not precipitate silent functional homogenization across the rapidly transforming African tropics.</p></div>","PeriodicalId":543,"journal":{"name":"Environmental Management","volume":"76 7","pages":""},"PeriodicalIF":3.4,"publicationDate":"2026-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148417500","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study explored trade-offs between profitability and biodiversity conservation across heterogeneous Estonian agricultural landscapes to support the development of economically effective grassland conservation schemes. To this end, we selected twelve ‘landscape windows’ in a grassland-rich region that represent a gradient of several biodiversity-related landscape factors (semi-natural grassland share, yield potential and landscape complexity). Profitability was assessed using total gross margins derived from a bio-economic model, while biodiversity was evaluated through habitat values for different bird species, based on model outputs. We found that landscapes with higher complexity, which currently maintain higher biodiversity levels, had a corresponding lower farm profitability. In particular, landscape windows dominated by semi-natural grasslands with low grass yields showed the lowest profitability, largely due to limited capacity for feeding beef cattle. In contrast, arable land-dominated landscapes (i.e. those with higher yield potential) demonstrated considerable potential for enhancing biodiversity outcomes while minimising profitability losses. Therefore, conservation policy faces two main challenges: 1. preserving landscapes with high biodiversity value against further decline in profitability, 2. highlighting the need to explore and design biodiversity measures in arable-dominated landscapes that could improve biodiversity outcomes while limiting impacts on farm profitability.

Then, we compared the directions observed in the sampling with hypothetical directions measured from a hypothetical route that birds may use, defined from the spatial arrangement of THG cover in the village, the surrounding forest fragments, and the location of the sampled THG. Our results show that most birds departed in the opposite direction from which they arrived, suggesting that THG act as biological stepping stones, forming corridors that enhance connectivity between fragmented habitats. This pattern was consistent when analyzing the complete assembly and across most trophic guilds, except for granivorous birds. Comparing observed arrival and departure directions with hypothetical directions shows that birds move through the THG along routes connecting the forest fragments surrounding the village.
