Location – Ecosystem

The JOI project is part of Auroville, an international township in Tamil Nadu, India, and lies within the landscape of the tropical dry evergreen forest (TDEF). Its ecological work connects to the larger community’s long-standing reforestation initiatives, which have transformed degraded lands into thriving forest ecosystems. Though modest in scale, our sub-project is part of a larger 3,930-acre Auroville reforestation initiative—a 50-year restoration effort aimed at reviving a desertified landscape that was once a thriving TDEF.
Historical records confirm that this biome supported wildlife such as elephants and tigers (Nagy & Szabó, 2019). However, by 1825, widespread deforestation had cleared much of the land for settlements, while colonial land policies accelerated habitat loss (Blanchflower, 2005; Meher-Homji, 1992; Parthasarathy et al., 2008; Wikramanayake, 2002; Auroville, n.d.; Regenerative Auroville, 2010).

Principles of Reforestation

Auroville’s reforestation ethos is rooted in restoring ecological balance and strengthening resilience. The community focuses on:

  • Biodiversity restoration through the propagation of native TDEF species.
  • Soil regeneration with composting, mulching, and erosion control techniques.
  • Water management via rainwater harvesting, contour bunds, and aquifer recharge.
  • Community participation, engaging residents directly in restoration.
  • Education and awareness to instil ecological stewardship across generations.
  • Renewable energy integration to reduce the footprint of restoration work.

Achievements and Practices

Over five decades, Auroville has demonstrated the transformative potential of reforestation:

  • Protection and propagation of indigenous TDEF flora.
  • Erosion control with bunds, check dams, and vegetated watercourses.
  • Creation of biodiversity parks for conservation and learning.
  • Use of agroforestry systems blending restoration with sustainable livelihoods.
  • Decision-making rooted in ecological feedback and adaptive practice.

Restoration Efforts: Local Solutions to Global Biodiversity Challenges

In six years, our sub-project has created habitat for a range of bird species, including sunbirds, bee-catchers, woodpeckers, and kingfishers. Table 1 outlines the IUCN status, population trends, ecological roles, and restoration benefits of selected resident species, highlighting the impact of community-led initiatives in linking local restoration with global biodiversity goals.

Figure 2: Landscape Restoration Progression in South-East India: A time-series from Google Earth (captured in February to minimise seasonal variation) illustrates our sub-project’s ecological recovery. The left panel shows the site in February 2018, prior to restoration. The middle panel, from February 2024, demonstrates the effects of water catchment techniques and tree planting. The right panel situates our work (south-bottom) alongside the 30-year-old restored site known as Aurodam (north-top), underscoring ecological connectivity.


Table 1: This table lists bird species observed in our restored habitat, detailing their global IUCN status, IUCN population trend, ecological role, and inferred restoration impact. The Population Trend reflects global data and may not represent local changes, as site-specific data is unavailable. Ecological Role highlights each species’ contribution to ecosystem processes and ecosystem services  (e.g., pollinator, insectivore). Benefits from Restoration indicates potential advantages or challenges based on species’ ecological needs. Data sources include IUCN and BirdLife International for global status and trends, while restoration impacts are speculative based on typical habitat requirements.
