Broad Thematic Area 6: Physical Connectivity

Significance of Physical Connectivity in the India Himalayan Region (IHR)

Good physical transport connectivity is most important infrastructure for country progress. However, in the mountain region, road is the only viable means of transportation. But, construction and maintenance of hill and mountain road are often challenged by its topography, fragile geological conditions, and climate conditions. The conventional road often causes of landslides, deforestation, increase slope instability, air pollution, deterioration ecosystem etc. Additionally, this region has lower population density and lacks basic infrastructural facilities available in plain terrain. Hence, an adequate and long lasting road network is very much necessary in Himalayan areas for overall development of the region as well as fulfilling defence needs. The present specialized techniques such as Safer Road, Green Road can be used to alleviate above problems. These technologies follow the philosophy of promoting energy-efficient and minimum disruption to existing vegetative cover and re-utilization of the excavated materials as construction material. Other advantages are stabilizing the roadside slopes, reduce soil erosion, off-farmer employment opportunities, less transportation cost etc. In this direction, the following 02 projects are ongoing under the NMHS, which aims to directly address alternative transport connectivity in mountain region.

Overall Objectives

Addressing the problem of locally available materials and enhancing their performance by means of geo-synthetics;
Providing satisfactory pavement composition for roads constructed at high altitudes using locally available/marginal materials.
GIS based database with respect to road network, settlement locations with demographic details and crash data of Tripura State
Development of various indices to assess the ease of reaching at various facilities desired by residents within settlement or at nearby major settlements through safe road connectivity.

Ongoing Projects: 2 (MG-02 & SG-01)

FY 2017-18
1 Sustainable road pavements in high altitude regions using geosynthetics.
2 Safe road connectivity for Tripura State of north region of India..
3 Hyperspectral imaging for sharper definitions of Himalayan ecosystems and its high value plant species under climate uncertainties.

Measurable Targets up to 2020

Safe road connectivity in at least two (2) IHR States of the IHR as pilot project
