このレビューは、インド・バンガロールの急速な都市拡大とそれに伴う土地利用変化、エネルギー需要増加が、人為的温室効果ガス排出を通じて都市気候にどのような影響を与えているかを総合的に評価した。衛星データや地上観測から、都市表面温度の上昇、降水パターンの変動、洪水リスクの増大などが確認された。しかし、包括的な都市レベルのGHGインベントリの欠如が正確な排出量推定の障壁となっている。政策枠組みの評価とデータギャップの解消が今後の課題である。
English
This review synthesizes evidence on anthropogenic GHG emissions driving urban climate change in Bengaluru, India. It documents a dramatic expansion of built-up area from 69 km² in the 1970s to 455 km² by 2010, with associated loss of vegetation and water bodies. Findings show measurable warming, increased precipitation variability, and heightened flood and heat stress risks. The review identifies gaps in city-level GHG inventories and recommends priorities for improving climate governance.

日本のGX文脈において
本論文は、バンガロールの事例を通じて、都市拡大に伴う温室効果ガス排出と気候変動の関係を明らかにしている。日本の都市でも同様の課題があるが、特に包括的な都市GHGインベントリの重要性を示唆しており、SSBJや自治体のカーボンニュートラル戦略策定に参考となる。
In the global GX context
This paper contributes to the global literature on urban climate change by providing a detailed case study from a rapidly growing Indian megacity. It highlights the need for better city-level emission inventories and climate observation networks, which are critical for ISSB-aligned disclosure and transition planning.
👥 読者別の含意
🔬研究者:Researchers can use this review as a reference for urban GHG emission attribution studies and for identifying data gaps in developing city-level climate models.
🏢実務担当者:Practitioners in urban planning and sustainability teams can learn from Bengaluru's experience in linking land use change to climate impacts, aiding in climate risk assessments.
🏛政策担当者:Policymakers should note the importance of establishing comprehensive city-level GHG inventories to support evidence-based climate governance and adaptation planning.
📄 Abstract（原文）
Bengaluru, India's foremost technology hub and the capital of Karnataka state, has experienced one of the most rapid urban expansions in South Asian history, transforming its physical landscape, energy demand, and atmospheric composition over barely four decades. This critical narrative review synthesises peer-reviewed evidence on the role of anthropogenic greenhouse gas (GHG) emissions in driving urban climate change in Bengaluru, drawing on published research spanning land use and land cover change, sectoral emission analysis, surface temperature and precipitation trends, urban heat island dynamics, and climate policy evaluation. The review documents a dramatic expansion of Bengaluru's built-up footprint — from approximately 69 square kilometres in the early 1970s to approximately 455 square kilometres by 2010, with continued growth thereafter — accompanied by a precipitous decline in vegetated cover and the loss of many of the city's historically extensive water bodies. A narrative synthesis methodology was adopted for this review. Relevant literature was identified through systematic searches of major scientific databases using predefined search strings combined with Boolean operators. These landscape transformations, combined with emissions from transport, energy consumption, and industry, have contributed to measurable warming of the urban surface, elevated pollutant concentrations, increased precipitation variability, and heightened risks of flooding and heat stress. Whilst precise emission attribution remains constrained by the absence of comprehensive city-level GHG inventories and high-resolution climatic observation networks, convergent evidence from remote sensing, atmospheric science, and surface observations points to a significant anthropogenic contribution to Bengaluru's changing climate. The review critically evaluates national and subnational policy frameworks, identifies key methodological and data gaps, and recommends priorities for strengthening the evidence base in support of equitable and effective urban climate governance.
