Summary
This summary is machine-generated.This study reviewed urban Blue-Green Infrastructure (BGI) research in South Asia, finding a focus on green spaces and sustainability benefits but gaps in holistic implementation strategies and governance.
Area Of Science
- Environmental Science
- Urban Planning
- Sustainability Studies
Background
- Urban Blue-Green Infrastructure (BGI) is crucial for sustainable urban development.
- Research on BGI in South Asian lower-middle-income countries (LMICs) is growing but unevenly distributed.
- Understanding the current research landscape is vital for advancing BGI implementation.
Purpose Of The Study
- To systematically review research on urban Blue-Green Infrastructure (BGI) in South Asian LMICs (India, Bangladesh, Sri Lanka, Bhutan, Nepal, Pakistan).
- To analyze BGI research trends, components, applications for urban sustainability, and identify knowledge gaps.
- To assess regional variations in BGI research focus and implementation challenges.
Main Methods
- Systematic Literature Review (SLR) of 77 publications from 2013-2022.
- Analysis of BGI mentions, components, uses, and research priorities across South Asian countries.
- Identification of research gaps related to BGI scope, creation, management, governance, and integration.
Main Results
- Research is concentrated on green spaces over bluescapes, with common themes including public perception, nature-based solutions, and mitigating urban heat island and air pollution effects.
- Significant disparities in research output exist among South Asian countries.
- Challenges in BGI governance, implementation, and holistic design methodologies were frequently highlighted.
Conclusions
- While research acknowledges BGI's benefits for urban sustainability, a significant gap exists in holistic implementation strategies, encompassing scope, creation, management, and governance.
- Integrating BGI with existing grey infrastructure requires further investigation.
- Future research should focus on developing comprehensive frameworks for BGI implementation and governance in South Asian urban contexts.

Flood risk assessment involves careful planning and analysis to ensure the safety of communities near water retention structures. Capacity contours are a vital tool in this process, as they illustrate the potential spread of water at specific levels in a given area. In the context of building a bund across a small valley, these contours play a critical role in evaluating the safety of nearby residential areas.In this example, the bund is intended to store stormwater in the valley. The engineers...
Water plays a significant role in the life cycle of plants. However, insufficient or excess of water can be detrimental and pose a serious threat to plants.
Under normal conditions, water taken up by the plant evaporates from leaves and other parts in a process called transpiration. In times of drought stress, water that evaporates by transpiration far exceeds the water absorbed from the soil, causing plants to wilt. The general plant response to drought stress is the synthesis of hormone...
The alignment of a road line using Geographic Information Systems (GIS) is a critical process in civil engineering, combining advanced technology with practical decision-making. This methodology begins with the collection of geospatial data, including information on land cover, geomorphology, drainage patterns, slope, and contour details. Such data is typically acquired through satellite imagery and GIS tools, offering a comprehensive understanding of the terrain.Once the data is gathered, it...
Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.
In land plants, the uppermost cell layer of a plant leaf, called the epidermis, is coated with a waxy substance called the cuticle. This hydrophobic layer is composed of the polymer cutin and...
In the past, planning projects such as schools or public facilities required extensive manual effort to gather and compile data. Information such as property boundaries, soil characteristics, road networks, zoning regulations, and flood zones had to be sourced individually from courthouses, utility providers, and registry offices. Assembling these datasets into a coherent format often took several months, delaying project timelines.The introduction of Geographic Information Systems (GIS)...
Geographic Information System (GIS) technology is essential for risk identification, action prioritization, and resource optimization in critical situations like flooding and earthquakes. By integrating spatial and demographic data, GIS provides a comprehensive framework for emergency response.GIS integrates data layers, like rainfall intensity, topography, elevation profiles, and river levels, to model high-risk flood zones. These layers assess areas susceptible to flooding based on their...
