Summary
This study assesses sustainable development in 16 Silk Road Economic Belt (SREB) countries. Israel ranked highest, while India showed the lowest sustainability performance, highlighting regional disparities.
Area of Science:
- Environmental science
- Economics
- Regional studies
Background:
- The Silk Road Economic Belt (SREB) initiative aims to foster connectivity across Asia, Europe, and Africa.
- Participating regions face complex environmental and socio-economic challenges impacting sustainable development.
- Assessing sustainability is crucial for effective regional policy and development within the SREB framework.
Purpose of the Study:
- To evaluate and rank the sustainability performance of 16 countries central to the SREB.
- To identify disparities in sustainable development across South Asia, West Asia, and Africa.
- To provide data-driven insights for SREB regional policy planning.
Main Methods:
- A hybrid multi-criteria decision-making approach was developed.
- The Method based on the Removal Effects of Criteria (MEREC) determined objective indicator weights.
- Operational Competitiveness Ratings Analysis (OCRA) evaluated and ranked countries based on sustainability indicators.
Main Results:
- Significant variations in sustainability performance were observed among the 16 studied countries.
- Israel achieved the highest sustainability ranking.
- India exhibited the lowest sustainability performance, with Sri Lanka and Nepal ranking highly.
Conclusions:
- The study highlights critical sustainability gaps within the SREB regions.
- Findings offer valuable benchmarks for future sustainable development initiatives.
- Strategic policy interventions are needed to address identified disparities and promote equitable growth.

01:17Design Example: Alignment of a Road Line Using GIS
27
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...

177
Designing a structure involves a series of considerations, primarily the material's ultimate strength, calculated through tests that measure changes under increased force until the material reaches its breaking point or limit. The ultimate load, where the material breaks, is divided by its original cross-sectional area, resulting in the ultimate normal stress or strength. The ultimate shearing stress is another significant factor taken into account.
