Summary:

More people live close to sea coast than earlier estimated, researchers have concluded after a new study. These people are the most vulnerable to the rise of the sea level, increased number of floods and intensified storms. By using recent increased resolution datasets, researchers estimate that 1.9 billion inhabitants, 28% of the world’s total population, live closer than 100 km from the coast in areas less than 100 meters above the present sea level.

• By 2050 the amount of people in that zone is predicted to increase to 2.4 billion, while population living lower than 5 meters will reach 500 million people. Many of these people need to adapt their livelihoods to changing climate, say Assistant Professor Matti Kummu from Aalto University.The study found that while population and wealth concentrate by the sea, food must be grown further and further away from where people live. Highlands and mountain areas are increasingly important from food production point of view, but also very vulnerable to changes in climate.
• Over the past century there has been a clear tendency that cropland and pasture areas have grown most in areas outside the population hotspots, and decreased in coastal areas. This will most probably only continue in the future, summarises Professor Olli Varis from Aalto University…….http://www.sciencedaily.com/releases/2016/03/160308105053.htm
