Red Sea Mangroves Fight Back in the Face of Global Decline

Excerpts;

Mangroves are superheroes on both land and sea, storing carbon and providing protection for coasts.

The Red Sea is one of the world’s saltiest and warmest seas. It is an extremely harsh environment, surrounded by desert and subject to very high temperatures. No rivers empty into the sea, which, along with the warm conditions, give it its high salt content. The mangroves found along the Red Sea coasts are some of the northernmost in the world.

However, there has been no decline in mangrove stands in the Red Sea – the body of water that runs between Africa and the Arabian peninsula.

The extreme conditions mean that the mangroves of the Red Sea have been subjected to much lower levels of human activity than elsewhere.

Cost-effective solutions to sediment runoff and other land-based pollution affecting West Maui reefs


Photograph: © SAF — Coastal Care

Excerpts;

Land-based pollutants have been linked to the degradation of several Hawaiian reefs.

Between 2000 and 2015, coral cover on West Maui’s northern reefs has dramatically declined from 30 percent to 10 percent. The likely culprit: sediment runoff during rain events. Corals’ ability to photosynthesize and grow is compromised in the presence of sediment, which in turn allows for algae to take over…

Original Study: “Where Land Meets the Sea: A Global Review of the Governance and Tenure Dimensions of Coastal Mangrove Forests,” Center for international forestry research; (2016)
This report provides a synoptic analysis of the legal and governance frameworks that relate to the use and management of mangrove forests globally. It highlights the range of challenges typically encountered in the governance and tenure dimensions of mangrove forest management. This assessment forms part of a broader study that includes national-level assessments in Indonesia and Tanzania. It was carried out under the USAID-funded Tenure and Global Climate Change Program. The report provides information on the challenges for mangrove rehabilitation and restoration, legal frameworks for the governance of mangroves, mangrove governance and tenure in practice, and lessons in mangrove governance for policy and practice. Primary findings from this assessment show that authority over mangrove forest management is overwhelmingly vested in state institutions and that mangrove protection is a central objective. Given the ambiguous role of mangroves situated between the land and sea, the configuration of state authority for mangrove management is quite complex. In some countries, there is fragmentation of responsibilities across two or more agencies such as forests, fisheries, environment, and wildlife. This contributes to a high level of segmentation and jurisdictional ambiguity. Frameworks and mechanisms for enabling multi-sectoral coordination across agencies and governance levels are uncommon, and where they exist, they are difficult to put into practice…

The Human Element of Mangrove Management

Excerpts;

As global climate change continues to threaten coastal communities in the tropics, governments have increasingly focused on the promotion and conservation of mangrove forests for their protective qualities.

Mangroves — trees and shrubs that grow in tropical estuaries — are among the world’s most productive ecosystems and, compared to other forest systems, have an impressive capacity to sequester and store carbon at high rates. They also serve as an important physical buffer, protecting coastal areas from storm surges and acting as “bioshields.” Despite these clear benefits, since 1980 the world has lost approximately 20 percent of its mangrove forests. With this in mind, there is a growing need to understand the factors, both biophysical and societal, that contribute to sustainable mangrove management.

To date, discussions around mangrove forest conservation and rehabilitation have been highly technical, and focused primarily on ecological conditions under which mangroves can be planted and promoted. Lacking from this conversation is a more robust analysis about the ways land governance, resource rights arrangements, and land use planning — the social aspects of the conservation challenge — affect mangrove conservation and rehabilitation…

A blob of a coral has been caught violently pulsating, with tentacles wriggling every which way, as it ejects its algal residents in a time-lapse video of the phenomenon called bleaching.

The video revealed for the first time how the mushroom coral Heliofungia actiniformis, which is a single polyp, physically reacts to heat stress. The results gave scientists more information about how corals will respond to warming seas that are associated with climate change, the researchers said…
