Developing countries face decreases in both fisheries and agriculture production under climate change

The authors looked at how food production on land and in the sea will be threatened by climate change and what the future effects on biodiversity, livelihoods and food security will be. They adopted the human development index (HDI) — a global index of life expectancy, education and per capita income. They found that all of the low human development index countries will face declines in both agriculture and fisheries production by 2050.

Global change in the trophic functioning of marine food webs

The rapid development of fisheries in the 1950’s facilitated declines in predator biomass, overexploitation, collapse of fish stocks, and degradation of marine habitats. A new PLOS ONE paper investigates past changes in trophic functioning of marine ecosystems cause by human-induced changes in species assemblages by applying an ecosystem approach to fisheries.

Adaptive capacity: from assessment to action in coastal social-ecological systems

Coastal ecosystems are undergoing complex changes caused by both social and ecological drivers occurring at varying scales and speeds, which ultimately act as either risks or opportunities to coastal social-ecological systems. The assessment of adaptive capacity of coastal ecosystems is crucial in understanding the extent to which they will be able to accept and adapt to these social and biophysical drivers.

REPORT – Oceans and Sustainable Development Goals: Co-Benefits, Climate Change and Social Equity

A healthy ocean will benefit global sustainable development in a number of ways, finds a new report published today by the Nippon Foundation-Nereus Program. With climate change and social inequity addressed, restoring the ocean will help alleviate poverty, provide livelihoods, and improve the health of millions around the world.

Solutions to blue carbon emissions: Shrimp cultivation, mangrove deforestation and climate change in coastal Bangladesh

Bangladesh is a world leader in aquaculture production, ranking sixth after China, Indonesia, India, Vietnam, and the Philippines. Due to the nation’s favourable physical characteristics, Bangladesh is highly suitable for coastal aquaculture, especially the tiger shrimp sector. Shrimp culture has diversified livelihood opportunities for coastal communities, as over two million people are involved in fish farming, market, processing, and exporting.
