A Green Rise to Energy and Food Security

Print

To address the challenge of sea level rise, we have developed a novel action plan to minimize the effects of RISE on social life and economy, as well as providing tools for energy and food security before the year 2100. The plans include dynamic adjustment of shorelines level to prevent floods and land usage conversion plans for agriculture.

overview of the idea

Several studies have shown sea level rise will increase tremendously in 21st century as a result of continental glaciers retreat and ice caps, and expansion of the upper ocean. The rise in the sea level can cause a catastrophe in the marine cities when added up with flood and tsunami. Therefore, proper adaptation action plans is necessary to encounter this inevitable challenge. Based on the “Sea Level Rise Adaptation Primer” published in Fall 2013, the four groups of adaptation strategies includes “Protect”, “Accommodate”, “Retreat”, and “Avoid”. Our proposed operational plan for encountering the rise challenge by 2100 includes two major tools to be used in “Protect” and “Accommodate” sections.

The first proposed tool is the development of novel dynamic shorelines along with auxiliary dikes, which provides sea level rise protection and tidal/ wave energy generation in the same time. Utilizing floating shorelines the human-sea interaction will remain almost intact, while the auxiliary dikes prevent the shorelines from possible floods and tsunamis. Also, the installation of proper structures enables tidal energy harvesting as an alternative source of sustainable energy if environmental issues are considered.

The second proposed adaptation tool is based on gradual farmland usage conversion from sea-side agriculture to aquaculture in order to adapt agriculture industry with upcoming situations, as well as utilizing modern farming techniques such as multi-level greenhouse farms instead of conventional farms. These approaches decrease the vulnerabilities of the farmers to sea level and climate conditions variability to a high extent. 


how it works

The main previously proposed method of protection is increasing the height of flood defenses, for which the social effects are considerable. In our proposed operational plan, recreational shoreline areas adapt themselves with variations in the sea level dynamically, while preserving human-environment interactions.

In this plan, floating shorelines are pivoted from one end and the floating end uses scour protection from bottom and sides. Moreover, introducing auxiliary dynamic dikes through proper canalling prevents flood risks to a higher level in the case of tsunamis. The non-recreational shorelines will be developed with more freedom in movement based on the tidal waves, which enables tidal energy harvesting. Studies show that the amount of harvested tidal energy can be significant.

Studies have shown that +1 metre rise in the sea level in Greater Vancouver affects up to 30% of the agricultural fields, which eventually affects food availability and cost, as well as life quality of agricultural workers. Our adaptation plans for related industries include farming adjustments and land usage conversions, from seaside farming to aquaculture, and utilizing modern farming techniques as in multi-level greenhouse agriculture.

In these plans, land usage will be converted to aquaculture including fish, algae, marine plants, and hydroponics farms. Therefore, not only agriculture effects of sea level rise will reach to minima, but also the food and biofuel availability challenge is being addressed. Moreover, conversion from traditional fields to modern farming and multi-level greenhouses insulates the farmers from sea level rise issues as well as climate variability.

How communities will adapt and thrive

The preventive dynamic shoreline  level adjustment plan includes both the introduction of dynamically floating recreational shorelines to minimize the effect of sea level rise on human and sea interactions while considering emergency flood situations by utilizing auxiliary dikes, and the introduction of dynamic dikes structures for non-recreational shorelines. In the former plan, the community’s social life with regard to sea will remain intact. The latter plan, not only will dynamically adjust its level such that the flood prevention is performed, but also the installation of proper tidal energy harvesting structure will address the energy challenge, by getting access to a tremendous source of sustainable energy source.

The “Adaptive Farming Adjustment” operational plan includes the tools to insulate agricultural workers from the side effects of sea level rise; hence, preserving the food availability and reasonable price. Land usage conversion from agriculture to aquaculture including marine plants, and hydroponics farms, will enhance the efficiency of traditional crops and will adapt the farm such that they remain almost intact with the sea level rise. The more efficient farming can address food and energy crisis by the year 2100.

Moreover, conversion from traditional fields to modern farming and multi-level greenhouse agriculture insulates farmers from sea level rise issues as well as climate variability. Although, this plan will rise issues such as farmers vulnerability to energy availability and cost, but the issues can be facilitated by proper land usage conversion and government motivate and relief programs such as subsidizations, etc.
