This study assesses the impacts of climate change on water resources over Mbarali River sub-catchment using high resolution climate simulations from the Coordinated Regional Climate Downscaling Experiment Regional Climate Models (CORDEX_RCMs).
Coastal cities are dynamic, complex systems which need energy, water, food and other resources to function and support diverse activities. If managed properly cities have the potential to offer better socio-economic conditions and quality of life to residents as well as the wider nation within which they are situated. The integrated adaptive management and sustainable development of coastal cities is therefore essential.
The Western Indian Ocean contains 16% of the world’s coral reefs, and the region is now thought to host the second peak of coral reef biodiversity globally. Coral reef ecosystems underpin the economies of the countries in the region, particularly fisheries and tourism sectors, and provide livelihood opportunities and income for local communities.
The Northern Mozambique Channel (NMC) area is under the jurisdiction of Madagascar, Mozambique, Tanzania, France, Seychelles and the Comoros, covering an area of approximately 700,000 km2. It is among the world's richest regions for biodiversity. It serves as a biological reservoir for the entire Eastern African coast, in particular for coral reefs and associated ecosystems, and is an important breeding and foraging areas for flagship marine and migratory species.
The United Nations Agenda 2030 further enshrines the central role of the ocean for sustainable development through Goal 14 (SDG14), to "conserve and sustainably use the oceans, seas and marine resources ", to lift millions of people out of poverty. The 2017 United Nations Oceans Conference provided a platform to focus countries' and other stakeholders' attention on commitments to achieving SDG14 at national and regional levels.
Seamounts are active or extinct volcanoes located on mid-oceanic rifts or intra-plate hot spots. Because of their magmatic origin, seamounts contain mineral resources. A crust of ferromanganese oxide enriched with cobalt, copper, manganese and sulphur has accumulated around the oldest reliefs. These reserves could exceed the quantities currently present on the continents, but their extraction cost remains prohibitive to be profitable.
The economic and socio-political interactions between countries can have major impacts on transboundary conservation decisions and outcomes. Here, we examined for 14 Western Indian Ocean (WIO) continental and island nations the extent of their marine coral reef species, fisheries and marine protected areas (MPAs), in the context of their geopolitical and socio-economic connections. We also examined the role of external countries and organisations in collaboration within the region.
Aim To describe, model and assess the relative importance of environmental and climatic factors likely influencing the regional distribution of coral cover and assemblages with contrasting life histories and susceptibilities to bleaching. Location We compiled the first comprehensive empirical dataset for coral communities in the south‐eastern Indian Ocean (SEIO), incorporating information from 392 sites along the western coast of Australia and offshore atolls/islands across ~19° of latitude.
