Somewhere in the Caribbean, Natural Girl realizes she has been in a toxic relationship for too long and decides it's time for a long overdue break-up.
Reduce and reverse land degradation at selected Quarry site(s) in the North East of Trinidad using an integrated water, land and ecosystems management approach.
The Aripo Savannas, located in North Eastern Trinidad, is designated as an Environmentally Sensitive Area (ESA) and Strict Nature Reserve under Trinidad & Tobago’s Environmental Management Act (2000). It includes unique habitats, rare and endemic biodiversity and is of great scientific importance. The Savannas provide important ecosystem services - water resources for both aquifer recharge and direct extraction, high quality sand and gravel deposits for construction, and livelihoods for many associated in the quarrying industry.
Quarrying in this part of Trinidad started in the 1940s to meet national demand for aggregate materials by the building and road construction industries. Poor regulation over the years has led to indiscriminate quarrying, resulting in severe land degradation as existing vegetation and top soil is cleared leading to loss of habitat, wildlife and plants. Watercourses are polluted by large quantities of sediment from erosion and from wash plants, and this eventually is transported to the sea, affecting coastal water quality badly.
Given the sensitivity of the ecosystems within the North East area, focussing attention on the restoration and rehabilitation of the degraded quarry areas was deemed to be of high priority by the Government of Trinidad & Tobago and is the focus of their IWEco National sub-Project.
The overall objective of this sub-project is a reduction in risk posed by land degradation at selected quarry sites in the northeast of Trinidad through the employment of an integrated water, land and ecosystems management approach.
The major two outcomes of this project will be: 1) To reduce the scarring of the landscape through the implementation of appropriate rehabilitation techniques and 2) To reduce the impact on the natural and socio-economic environment through the application and adherence to international best practice for quarry operators and improved adherence to local legislation.
The Project was launched in May 2018 with a 48-month timeline. National Quarries Company Limited (NQCL), the state owned and operated quarry, located in Guaico, was chosen as the pilot training and rehabilitation site. It consists of three areas:
The National Project Steering Committee (NPSC) held its first meeting in August 2018. It is made up of representatives of various ministries and agencies responsible for overseeing and managing sustainable quarrying in Trinidad and Tobago. These include: the Ministry of Energy and Energy Industries; the Ministry of Planning and Development- Town and Country Division and Environmental Division; the Ministry of Agriculture Land and Fisheries- Forestry Division and Commission of State Lands; the Water Resources Agency and the Project’s national executing agency, the EMA.
In September 2018, two non-governmental organizations, the Trust for Sustainable Livelihoods (SUSTRUST) and IAMovement (IAM), in collaboration with the United Nations Development Programme - Small Grants Programme, began developing a quarry rehabilitation training programme as part of the project’s livelihoods programme. Between September and December, twenty-seven persons from surrounding communities underwent a 4-month programme of classroom and field work at the pilot sites. These “Quarry Rehabilitation Champions” were trained in areas such as site preparation and planting, creation of check dams and fire tracing, nursery development, top-soil conservation and management, mulching and implementing vetiver as a rehabilitation intervention. This component aims to develop community capability thereby enabling replication at other, additional sites to be identified under the national sub-project.
In November 2019, Carib Glassworks, a privately managed sand quarry in the lower Matura area, partnered with IWEco.TT to rehabilitate a 2-hectare demonstration site using techniques such as live check dams, the planting of mixed forest species and vetiver grass for soil and slope stabilization. They are committed to matching an additional 1 hectare on site in 2021, using the techniques so far applied.
The establishment and implementation of an effective public awareness campaign to increase voluntary compliance by quarry operators and monitoring of quarries by regulatory agencies is another key activity. A draft document: “Guideline for the Preparation of Rehabilitation Plans” was completed by the EMA in December 2018 and is currently out for stakeholder review before finalization for publication and distribution in July 2019. Since March 2015, the EMA has required that a Rehabilitation Plan be submitted and approved by them prior to the commencement of mining/quarrying operations for which a Certificate of Environmental Clearance (CEC) has been granted. This guidebook is designed to assist applicants in submitting succinct and satisfactory Rehabilitation Plans.
