Background:
The Cayman Trench, also known as the Cayman Trough, is a deep-sea trench in the Caribbean Sea. It plays a crucial role in marine biodiversity due to its:
- Unique geological features: It is the deepest part of the Caribbean Sea, with depths reaching over 7,500 meters. This extreme depth creates a range of habitats from shallow coral reefs to deep-sea ecosystems. The trench is home to hydrothermal vent systems, particularly at the Mid-Cayman Rise. These vents release mineral-rich water that supports unique biological communities adapted to extreme conditions.
- Diverse marine habitats: The shallower regions of the Cayman Trench support extensive coral reefs, which are home to a wide variety of fish, invertebrates, and other marine life. The trench’s depth and varying conditions foster diverse deep-sea habitats, including abyssal plains and seamounts, which are often less explored and understood but vital for global biodiversity.
- Species richness: The unique environmental conditions of the Cayman Trench support species that are not found anywhere else. Hydrothermal vents, for instance, host endemic species of bacteria, tube worms, and other organisms that rely on chemosynthesis rather than photosynthesis.
- Migratory species: The trench and surrounding waters serve as important migratory routes for large marine species such as whales, sharks, and sea turtles.
- Ecological functions: The trench plays a role in global nutrient cycling. Hydrothermal vents contribute to the distribution of minerals and chemicals in the ocean, which can influence marine productivity. Deep-sea environments like the Cayman Trench are important for carbon sequestration, helping to mitigate the effects of climate change by storing carbon in the deep ocean.
- Scientific research and discovery: The unique ecosystems of the Cayman Trench provide opportunities for scientific research, particularly in understanding life under extreme conditions and the adaptations of deep-sea organisms. Organisms found in the trench, especially those around hydrothermal vents, are of interest for biotechnological applications, such as enzymes that can function under high temperatures and pressures.
- Conservation importance: The unique and often fragile ecosystems of the Cayman Trench are vulnerable to human activities such as deep-sea mining, overfishing, and climate change. Conservation efforts are essential to protect these habitats and their biodiversity. The trench’s biodiversity significance encourages international collaboration for conservation and sustainable use of marine resources, contributing to global efforts in marine conservation.
Protecting this area is crucial for maintaining marine biodiversity and the health of the global ocean ecosystem. Understanding and mapping current and past conservation initiatives in this region is essential for coordinating efforts, identifying gaps, and enhancing the effectiveness of conservation strategies.
Objective
The primary objective of this consultancy is to map and analyze past and on-going conservation initiatives around the Cayman Trench.

- Identify diplomatic limitations/opportunities derived from the multinational character of the possible intervention of the Caribbean Biodiversity Fund (CBF) and the Mesoamerican Reef Fund (MAR Fund) in the Cayman Trench. (e.g. Countries involved, Belize-Guatemala pending marine border definition, Cayman Islands as a self-governing British Overseas Territory, US-Cuba investment limitations, regional treaties, etc.)
- Develop a database of ongoing conservation projects, detailing their objectives, funding sources, political supporters, geographic scope, timelines, and outcomes.
- Analyze the effectiveness and impact of past and existing conservation initiatives, identifying best practices and areas for improvement.
- Identify gaps in research needs and current conservation efforts and recommend strategies to address these gaps.

Assistant for the MAR Fund Small Grants Program
1. Introduction
The Mesoamerican Reef Fund Inc. (MAR Fund) is a regional environmental fund whose main objective is to protect the Mesoamerican Reef (MAR) ecoregion shared by Mexico, Belize, Guatemala, and Honduras. Its mission is to seek, secure and facilitate regional funding, foster partnerships and drive capacity building for the conservation, restoration, and sustainable use of marine and coastal ecosystems in the MAR region.
MAR Fund was established by four pre-existing environmental funds, one in each country of the region: Fondo Mexicano para la Conservación de la Naturaleza (México), Protected Areas Conservation Trust (Belice), Fundación para la Conservación de los Recursos Naturales y Ambiente (Guatemala), and Fundación Biosfera (Honduras).
MAR Fund is incorporated in the United States as a nonprofit organization with 501(c)(3) tax-exempt status. Although it is legally registered outside the region, its purpose is to finance conservation and sustainable development actions in the four countries sharing the MAR ecoregion: Mexico, Belize, Guatemala, and Honduras. Since 2015, it has maintained a branch office established in Guatemala, where the coordinating office is located.
MAR Fund carries out its activities through six programs: 1) Saving Our Protected Areas, 2) Fishing for the Future, 3) Climate Change, 4) Belize Marine Fund, 5) Clean Water for the Reef, y 6) Blue and Regenerative Economy. Additionally, it supports and coordinates regional networks such as the Connectivity Network, the Reef Restoration Network, and the Fish Spawning Aggregation Sites Network.
The MAR Fund Small Grants Program (SGP) is one of its longest-standing and most flexible funding mechanisms. Thanks to its adaptability to regional challenges and threats, the SGP has supported strategic projects linked to all of the organization’s programs. The SGP is currently financed through endowment fund returns provided by German Cooperation through KfW and the French Global Environment Facility (FFEM), as well as programmatic funds from the Paul M. Angell Family Foundation. These resources have made it possible to promote local initiatives that, among other things, contribute to the protection of priority marine and coastal areas and the sustainable use of marine and coastal resources.
The SGP has two financial windows: 1) The Traditional window, which focuses on contributing to the conservation of MAR ecosystem functions and resilience; and 2) The Reef Rescue Initiative (RRI) window, which aims to support the restoration, repopulation, and rehabilitation of coral reefs in the MAR. Once a year, governmental and non-governmental organizations, academic institutions, civil society organizations, and organized community groups from the four countries of the MAR region have the opportunity to submit proposals addressing one or more of the specific objectives established in each request for proposals (RfP).
Since 2006, MAR Fund has launched 18 RfP, through which 159 projects have been supported and implemented by more than 40 civil society organizations, academic institutions, and government sector entities across the four countries of the region.
