Loss of marine ecosystems

Risk of loss of marine ecosystems of great importance to livelihoods in coastal areas

Extinction of coral with 2.5℃ rise in water temperature

Climate change will also wield considerable impacts on sea life. According to the IPCC report, if sea water temperatures rise by 1℃, the bleaching of coral will increase. Likewise, with an increase of 1 to 2.5℃ almost all coral would be bleached, and anything over 2.5℃ would reputedly cause the annihilation of coral over wide areas. Coral and sea grass beds have a high organism productivity and act to filter the sea. As the foundation of ecosystem services from the ocean, these impacts cannot be overestimated. Further, rising concentrations of CO2, the representative greenhouse gas, acidify the oceans, wielding impacts on marine ecosystems.
From the perspective of globally rising demand for food, the preservation of coastal ecosystems for the continued supply of ecosystem services from the oceans, such as supply of marine resources, becomes even more important. While not all the impacts on complex marine ecosystems can be elucidated, we must consistently ascertain changes in key coastal areas, determine their causes, and put in place measures that take into account impacts extending into the future.

What ICT can do for the preservation of marine ecosystems

ICT plays an important role in monitoring changes in the marine environment. When various kinds of sensors are used that measure sea water temperature, acidity, visibility and dissolved oxygen level, measurements can be carried out automatically according to objectives. If measurement data, images, and survey and research results from around the world are shared in the cloud, they will assist in analysis of global current conditions. Further, ICT can also be utilized in aquaculture for the stable supply of declining marine resources. Efficient and effective aquaculture can be supported by accumulating and utilizing a variety of expertise and data on feeding methods, water temperature and salinity concentration.

What NEC can contribute to addressing loss of marine ecosystems

Monitoring of the marine environment

In the preservation of marine ecosystems, it is first important to ascertain the current state of and secular changes to the ecological environment that wield impacts on ecosystems. NEC supports ocean monitoring using underwater sensors. These sensors are unaffected by weather, and can observe 24-hour real time marine information with high precision over long periods of time and wide areas. The creation of observation and monitoring systems of all types is possible by switching sensors and customizing software.

Support for aquaculture management

Concerns have arisen over the depletion of natural marine resources due to increased consumption of marine products along with an increasing global-scale population, changes in ecosystems due to the impacts of climate change, and overfishing. As such, the importance of aquaculture will rise even more into the future. Utilizing ICT, NEC supports daily recording and reporting related to aquaculture work, continuous monitoring of water quality and product raised, and analysis of data collected. In so doing, we contribute to recovery of marine resources and solutions of food problems, as well as the realization of schemes that can provide safe and sound marine products to consumers.
