1. Tanzania and Zanzibar: Regional Context

The United Republic of Tanzania is one of East Africa’s most ecologically diverse nations, home to globally renowned landscapes ranging from Mount Kilimanjaro and the Serengeti Plains to the coral-rich islands of the Indian Ocean.

Tourism plays a vital role in Tanzania’s economy, accounting for a significant share of national employment and foreign revenue. Yet, as in many coastal regions, the country faces a growing challenge: how to ensure tourism contributes to long-term environmental stewardship rather than resource depletion.

Zanzibar — a semi-autonomous archipelago within Tanzania — has become an increasingly important focal point for marine conservation, blue economy development, and sustainable tourism initiatives, particularly in the lesser-known island of Pemba.

2. Zanzibar Archipelago Explained

Pemba Island is part of the Zanzibar Archipelago, lying north of Unguja (commonly called Zanzibar Island), but it has a distinct historical trajectory. For centuries, Pemba was deeply integrated into Indian Ocean trade networks, influenced by Arab, Persian, and Swahili cultures. It became a major center for clove cultivation under Omani Arab rule in the 19th century, when Zanzibar emerged as the capital of the Omani Sultanate. Although Pemba was administered together with Zanzibar during the Sultanate and later under British colonial rule, it often remained economically and politically peripheral. After the 1964 Zanzibar Revolution and the subsequent union with Tanganyika to form Tanzania, Pemba was formally incorporated into Zanzibar’s semi-autonomous government, while retaining a strong sense of regional identity shaped by its unique history and social structure.

3. Pemba Island: The Green Heart of the Archipelago

Pemba Island, located north of Unguja (Zanzibar’s main island), is often referred to as “the Green Island” due to its fertile hills, dense vegetation, and agricultural abundance. Historically known for spice production, Pemba is also recognised as one of the most biodiverse areas in the Zanzibar archipelago.

The island is home to the Ngezi Forest Reserve, one of the last remaining indigenous forests in Zanzibar, supporting several endemic species including four endemic bird species.

With a population of approximately 550,000 people, Pemba’s coastal communities rely heavily on marine ecosystems for food security and income. This dependence makes the health of coral reefs, fisheries, and mangrove systems inseparable from long-term community wellbeing.

4. The Pemba Channel: A Global Marine Biodiversity Corridor

Between Pemba Island and mainland Tanzania lies the Pemba Channel, a deep-water marine passage reaching depths of 400–1,000 metres. It is one of the Western Indian Ocean’s most ecologically significant seascapes.

The channel functions as:

• A migratory route for marine mammals
• A refuge for threatened reef species
• A biodiversity hotspot linking coastal and deep-sea ecosystems

Surveys have identified at least 13 cetacean species in these waters, alongside complex coral reef systems and abundant pelagic fish populations.

The wider ecosystem includes:

• More than 40 threatened marine species
• Approximately 10 mangrove species
• Around 12 seagrass species

Together, these interconnected habitats form a highly productive but sensitive marine environment requiring coordinated protection across land and sea.

5. Manta Resort: Conservation-Led Hospitality and the Blue Economy Corridor

Introduction

Manta Resort is a conservation-led hospitality operation situated on the northern tip of Pemba Island. Established with the explicit goal of aligning tourism with long-term ocean protection, the resort functions not as a standalone lodge but as an anchor institution within a wider seascape-scale initiative: the Pemba Channel Blue Economy Corridor.

Through its presence, partnerships, and guest contributions, Manta helps finance marine protection, scientific monitoring, and community-led economic alternatives supporting both biodiversity and livelihoods.

The Pemba Channel Blue Economy Corridor

The corridor represents a large-scale, co-managed conservation and development framework supported by the Zanzibar Ministry of Blue Economy and Blue Alliance, a Zanzibar-based NGO.

Key elements include:

• 27,000 hectares of marine protected area
• 1,300 hectares of coral reef under active recovery
• 1,500 hectares of mangrove forests conserved
• Protection of 40+ threatened species

This governance model combines government authority, scientific management, and community participation.

Manta’s Role

Manta Resort plays a direct financial and operational role in sustaining the corridor. Guest stays contribute to:

• Marine patrols
• Ecological monitoring
• Enforcement of protected areas
• Conservation planning

The resort demonstrates how tourism can function as reef-positive economic activity, helping sustain long-term protection rather than accelerating degradation.

Community Partnerships

Manta’s impact is delivered through collaboration with:

• Blue Alliance / Ministry of Blue Economy – Corridor management, monitoring, reef-positive enterprise development
• DIRA – A community-owned development organisation (“vision” in Swahili)
• Kwanini Foundation – Livelihood diversification, education, alternative income generation

Together, these partnerships ensure conservation outcomes are directly linked to tangible community benefits.

6. The New Underwater Room / Underwater Hotel Concept

Architectural Concept, Engineering and Environmental Design

Overview

The Manta Underwater Room is a standalone underwater unit designed for accommodation and immersive experiences below the sea surface. The structure is developed for permanent placement in a marine environment, with high requirements for safety, durability, and comfort.

The unit represents a next-generation evolution of an established concept, built on more than a decade of documented operational experience. All systems, materials, and design solutions have been refined to deliver a significantly enhanced level of performance, reliability, and guest experience.

Beyond its technical innovation, The Manta Underwater Room is developed as a platform for marine conservation, community engagement, and sustainable coastal development.

Technical Overview

Floating underwater accommodation unit integrating marine structural systems and natural materials across multiple levels

Configuration:
