Nagar Van in Odisha: Importance, Benefits, and Landscape Planning
In This Article
What is Nagar Van
From a landscape architect’s perspective, a Nagar Van is more than an urban plantation or a collection of trees. It is a carefully planned ecological landscape that brings the functions of a forest into the urban environment.
The idea of Nagar Van is to transform suitable urban and peri-urban land into biodiverse, resilient and accessible green landscapes. These spaces can be developed on degraded land, unused public land, forest land or other sites where ecological restoration can strengthen the relationship between the city and its natural systems.
A well-designed Nagar Van should not simply focus on the number of trees planted. It should consider existing vegetation, soil, water, biodiversity, topography, microclimate, human movement and long-term ecological succession.
For landscape architects, this makes Nagar Van an opportunity to design landscapes where ecological restoration and public use work together.
Typical components may include:
Native and regionally appropriate tree plantations
Understorey planting with shrubs, grasses and groundcovers
Biodiversity and habitat zones
Nature trails and pedestrian paths
Butterfly and bird habitats
Herbal and educational gardens
Water conservation and rainwater management systems
Open spaces for nature-based recreation and learning
What is the Nagar Van scheme in India?
The Nagar Van initiative is part of the Nagar Van Yojana launched by the Ministry of Environment, Forest and Climate Change in 2020. The scheme aims to create urban forests across Indian cities to improve environmental quality and increase tree cover outside traditional forest areas.
Under this program, the government aims to develop hundreds of Nagar Vans and Nagar Vatikas across cities with municipal corporations and municipalities.
The scheme focuses on:
• Increasing green cover in urban and peri-urban areas
• Protecting local biodiversity and native plant species
• Improving air quality and reducing pollution
• Providing recreational green spaces for city residents
Typically, a Nagar Van covers an area of about 10 to 50 hectares, while smaller green areas called Nagar Vatikas may cover 1 to 10 hectares within city limits. These urban forests are often developed with participation from forest departments, municipal bodies, educational institutions, NGOs, and local communities.
Why Nagar Van Matters in Landscape Architecture
Cities are often planned around buildings, roads and infrastructure, with green spaces treated as leftover areas. A Nagar Van reverses this approach by placing ecology at the centre of landscape planning.
Landscape architects can help integrate ecological processes with human needs. Instead of designing a forest as a decorative green space, the landscape can be structured around existing ecological conditions and natural systems.
For example, an existing tree canopy can become the foundation for a biodiversity zone. Low-lying areas can be used for rainwater harvesting and wetland habitats. Existing contours can guide drainage and trail alignment, while native planting communities can create different layers of vegetation.
The objective is to create a landscape that works as an ecosystem while remaining meaningful and accessible to people.
Environmental and Social Benefits of Nagar Van
Urban forests can significantly contribute to the ecological health of growing cities.
A thoughtfully planned Nagar Van can:
Improve local air quality
Reduce the urban heat island effect
Provide habitat for birds, butterflies and other wildlife
Increase biodiversity within urban areas
Reduce noise and environmental pollution
Improve soil and water conditions
Support carbon sequestration
Provide shaded outdoor spaces
Create opportunities for walking, recreation and environmental education
The benefits are not limited to environmental performance. Access to natural landscapes also creates opportunities for community interaction, learning and everyday contact with nature.
This is particularly important in rapidly urbanising cities where residents may have increasingly limited access to natural ecosystems.
How Should a Nagar Van Be Planned?
Developing a Nagar Van should begin with understanding the site rather than immediately deciding where to plant trees.
A landscape architect typically begins with a detailed site assessment covering existing vegetation, soil conditions, hydrology, contours, drainage, climate, biodiversity, surrounding land use and movement patterns.
The design process can include:
1. Site and Ecological Assessment
Existing trees, vegetation communities, water systems, soil conditions and natural features should be mapped and evaluated. Healthy existing vegetation should be retained wherever possible.
2. Ecological Restoration
Degraded areas can be restored through soil improvement, native planting, removal of invasive species and regeneration of appropriate vegetation communities.
3. Native Planting Strategy
Plant selection should respond to the local ecology. A layered planting system of canopy trees, small trees, shrubs, grasses and groundcovers can create a more functional habitat than uniform tree plantations.
4. Water-Sensitive Landscape Planning
Rainwater harvesting, bioswales, recharge zones, ponds and other nature-based water-management systems can be integrated into the landscape.
5. Nature-Based Circulation
Walking trails should allow people to experience the landscape without fragmenting important ecological zones. Paths can follow existing contours and minimise unnecessary disturbance.
6. Biodiversity Zones
Different habitats can be created for birds, butterflies, pollinators and other urban wildlife. These zones can also become outdoor classrooms for environmental education.
7. Community and Interpretation Spaces
Small gathering spaces, interpretation centres, seating areas and educational installations can help visitors understand the ecological value of the landscape.
The result should be a living landscape that changes and matures over time, rather than a finished landscape dependent on constant beautification and maintenance.
Nagar Van in Odisha
For Odisha, the Nagar Van concept has particular relevance because of the state's diverse ecological landscapes, including forests, wetlands, coastal ecosystems and riverine environments.
Cities such as Bhubaneswar, Cuttack, Sambalpur, Rourkela and Berhampur can benefit from urban forest strategies that respond to their specific ecological and climatic conditions.
In Bhubaneswar, for example, Nagar Vans can become important ecological links between existing green areas and urban neighbourhoods. Rather than introducing a generic landscape character, each site can be designed around its existing vegetation, soil, water systems and local biodiversity.
Potential sites may include:
Degraded public land
Urban forest areas
Peri-urban landscapes
Underutilised government land
Ecologically sensitive areas suitable for restoration
Land along appropriate urban edges and green corridors
FAQs
What is Nagar Van in landscape design?
Nagar Van is an urban forest planned as a functional landscape rather than simply a tree plantation. Landscape design integrates native vegetation, biodiversity habitats, pedestrian trails, water management, open spaces and nature-based recreational areas to create a resilient urban ecosystem.
How does landscape design contribute to Nagar Van development?
Landscape design helps organise the site according to its existing ecology, topography, vegetation, soil and water systems. A landscape architect can develop zoning, planting strategies, circulation networks, habitat areas, water-sensitive landscapes and visitor spaces while minimising disturbance to the existing natural environment.
What plants are suitable for a Nagar Van landscape?
Native and regionally adapted plant species are generally preferred because they support local biodiversity and are better suited to the site's climate and soil conditions. A layered planting strategy using canopy trees, understory trees, shrubs, grasses and groundcovers can create a more natural forest structure.
What landscape elements should be included in a Nagar Van?
A well-planned Nagar Van can include nature trails, shaded seating areas, biodiversity zones, butterfly and bird habitats, herbal gardens, rain gardens, ponds, bioswales, interpretation areas and outdoor learning spaces. These elements should be integrated with the site's ecological character rather than treated as isolated features.
How can landscape design make Nagar Van more sustainable?
Sustainable Nagar Van design focuses on retaining existing trees, using native planting, reducing hardscape, conserving water, improving soil health and managing stormwater naturally. Designing for ecological succession and low-maintenance landscapes can also help the urban forest become more self-sustaining over time.
