Rehabilitation of Quarries (ROQ) with IWEco-TT

A project which played a critical role at kickstarting and learning the lay of the land for sustainable quarry rehabilitation efforts in Trinidad & Tobago

Degraded quarries are a long-standing and well-known scar on our landscape and local conscience in Trinidad & Tobago. The GEF IWEco Trinidad and Tobago Sub-Project was part of a larger regional effort aimed to rehabilitate and heal local degraded quarry sites. With a focus on northeastern Trinidad this project started with two strong partners, IAMovement (IAM) and the Trust for Sustainable Livelihoods (SUSTRUST) who joined with the EMA to work on regenerating the landscapes within the northeastern quarries, primarily at the National Quarries Company Ltd sand and gravel site in Sangre Grande. There were two (2) Phases, where Phase I in 2018 undertook the critical effort of onboarding members of local communities and equipping them with the know-how for land regeneration and biodiversity conservation efforts – and getting these activities going on the ground. This project was a lot of tough, hard work, working in challenging terrain, but at the heart of this project there were the brave heroes – these determined and interested community members who eventually evolved to become our first cohort of Quarry Rehabilitation Champions. This first group of 22 women and 8 men were pioneers and became experts at sustainable rehabilitation practices, using Nature-based (or natural) Solutions to address land degradation at the local quarries.

In phase II IAMovement scaled former activities and explored new approaches that supported land regeneration. The overall effort resulted in 35 ‘quarry champs’ being enabled to work on the fight against land degradation, having assisted with 25+ Acres of quarried land enriched and/or rehabilitated. Other key accomplishments of the project included over 900 cubic meters of organic matter diverted from landfills and used for topsoil rebuilding; 20,000+ vetiver plants installed for erosion control and revegetation; and 1500+ trees replanted to support Land Degradation Neutrality. In this project we explored a variety of organic waste materials for use in vital topsoil rebuilding activities, which included sargassum seaweed, spent grain, rice straw, chipped Acacia wood as well as grass and tree cuttings.

Thanks to good guardianship of National Quarries Company Limited (NQ), the regenerated lands now have long-term stewardship with IAMovement, and its key continuity project and partner Close The Loop Caribbean. Increased biodiversity has been observed revisiting and returning to these areas. IWEco is a project that tells a story of tenacity, and a valuable truth which was unearthed through some of the academic research also undertaken on the project has stuck with us and carried forward into all subsequent quarry rehabilitation activities by IAMovement – which is that the most effective quarry rehabilitation approaches for severely degraded land should focus on improving soil health first.

Compost, organic mulch and sprinkle of good science were some of the secret ingredients to the success we experienced with this project. With this experience we know now that when life is returned to the soil in our severely degraded quarries, Life on Land can experience a burst of regeneration, and quarried lands can thrive again.
