The names of many new companies and technologies created to address the impact of climate change on the marine ecosystem can evoke thrilling activities on the high seas. Wave killer Use a compressed air system to create a “wall” of bubbles up to 50 feet thick to prevent erosion and control waste and oil spills.This beginner It is a solar barge deployed by the Dutch non-governmental organization Ocean Cleanup along the rivers of Southeast Asia to collect tons of waste before it enters the sea. Nautical drone with Waste shark Establish and deploy autonomous drone fleets to sail in the ocean. The former collect weather and ocean data, and the latter collect garbage.

This (usually threatening) technical sample represents an increasingly diverse approach to combating ocean degradation-diversity is urgently needed because climate change has waged war on the health of the world’s oceans in many different ways.The level of carbon emissions raises air and water temperatures, which in turn causes the polar ice caps to melt so fast that NASA It is estimated that by 2100, global sea levels will rise by half a centimeter every year.

To cope with the challenge of climate warming, sea level rise is critical to many aspects of global sustainable development, but two aspects are particularly prominent. One is coastal habitats: as the world’s coastlines recede and degrade, the homes and livelihoods of one third of the world’s population living in coastal areas may undergo irreversible changes in this generation. The second is global food supply. Ignoring the economic setbacks caused by the global covid-19 pandemic, exponential growth in global trade and protein consumption has pushed ocean transportation and commercial fishing to increasingly unsustainable levels.

Increasing consumer demand and the systematic failure to recycle and manage solid waste have also increased the 150 million tons of plastic in the ocean today by 8 million tons. Marine Conservation Association. Marine plastic waste is both a direct inherent sustainability challenge-affecting various industries from aquaculture to tourism-and a harmful long-tail threat to the global ecology, as the ocean tide decomposes plastic waste into microplastics and infiltrates the food chain .This is an area where a broad response portfolio of technical support is expanding, from the aforementioned foam walls and waste-eating drone fleets to the creation of New polymer soluble in seawater, To manage information and insights about maritime business activities through sensors and analysis that supports artificial intelligence.

But more is needed-more technology deployment, more investment in innovation, more regulation and government supervision-to effectively alleviate the rise of ocean plastics and countless other threats to the world’s oceans.

In this context, MIT Technology Review’s customized content department, MIT Technology Review Insights, is launching a global research program to evaluate how to deploy new “blue economy” technologies and solutions to clean our oceans and reduce ocean-related issues. Carbon emissions and improve the sustainability of the maritime industry. The project will eventually release the “Blue Technology Barometer”, which will quantify where in the world’s coastal economies are creating and effectively deploying relevant technologies and solutions to address everything from reducing carbon emissions in container shipping and port logistics to addressing climate The challenge of change. Illegal, unreported and unregulated activities.

The barometer will assess these efforts in more than 50 coastal countries and regions around the world and rank them using econometric models based on massive amounts of data and forecasts from dozens of sources.The model and research methods will be created based on MIT Technology Review Insights Green Future Index-Our basic global ranking in terms of progress and potential for decarbonization-will be an important complement to our ever-expanding portfolio of comprehensive research projects on the role of research technologies in promoting sustainable development.

The barometer will also review national and transnational efforts to deploy technical, regulatory, and commercial solutions that can both address climate change and reduce damage to the marine environment and cryosphere. By evaluating this intersection of innovative thinking and action, the barometer aims to highlight which coastal economies are operating most effectively to ensure a blue tomorrow.
