Complex social-ecological interactions underpin many environmental problems. To help capture this complexity, we advance an interdisciplinary network modeling framework to identify important relationships between people and nature that can influence environmental conditions.
Without drastic efforts to reduce carbon emissions and mitigate globalized stressors, tropical coral reefs are in jeopardy. Strategic conservation and management requires identification of the environmental and socioeconomic factors driving the persistence of scleractinian coral assemblages—the foundation species of coral reef ecosystems. Here, we compiled coral abundance data from 2,584 Indo-Pacific reefs to evaluate the influence of 21 climate, social and environmental drivers on the ecology of reef coral assemblages.
The present study investigated diffusive emissions of methane (CH4) and nitrous oxide (N2O) to the atmosphere from three relatively small (3–120 km2) reservoirs (Masinga, Kamburu and Gitaru) on the Tana River (Kenya). Sampling was conducted biweekly in 2011, 2012 and 2013, at sampling sites upstream and downstream of these reservoirs while five sampling campaigns were carried out in 2011, 2012 and 2013 for different sites within each of the reservoirs.
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.
