Late in 2018, a bill was passed in Japan to widen the entry of immigrant workers. The bill was to mitigate severe shortage of labor amidst an aging population and falling birth-rates. Prime Minister Shinzo Abe described the bill as a much-needed reform to ensure the smooth functioning of Japanese  economy. The bill makes it easier for immigrants to work for longer duration in Japan.

More than 20% of Japan’s population is over 65 years old which is the highest proportion in the world. It is projected that by 2030, one in every three people will be above 65 years or older and one in every five will be 75 years or older.

The fertility rate has fallen to 1.4 children per woman in Japan which has been attributed to a host of factors including changing lifestyles, people marrying late, not marrying at all, and the economic insecurity of the younger generation. It is projected that by 2050, Japan’s population will decline by twenty million while the world population is expected to increase by two billion.

Japan has traditionally been quite homogenous with  very little diversity to show. This trend now appears to be changing as today nearly three million migrants live in Japan which is three times more than the figures of 1990. As the country struggles with a rapidly aging population and severely declining domestic labor, the number in all likelihood is only going to increase.

Conservative Prime Minister Shinzo Abe based his support for the reforms in immigration policy on demographic arguments.The conservative section of the parliament has been a staunch supporter but the left opposition has been critical of the bill citing concerns about a lack of regulation on the employers which could lead to over-exploitation of the workers. Prime Minister Shinzo Abe’s government promised to set up a hundred consultation centers nationwide for dealing with issues related to workplace abuse specifically for the migrant workers.

However, that’s as far as those resisting the bill have gone. Nationalist and xenophobic voices protesting the bill have failed to gather steam. In fact, according to a survey by Nikkei in January 2020, almost 70 percent of Japanese said it is “good” to see more foreigners in the country.

Japan’s aging population has made it difficult to find the workers and some companies have more than 120 job openings for every 100 job seekers nationwide. Quite evidently, immigration now appears to be the most feasible solution for Japan- a country that has traditionally been restrictive with its borders when it comes to ethnic diversity.

Plant- Microbial fuel cell: Generating electricity from green, living plants

Humans are capable of discovering and creating great things with the help of science and one such impressive discovery is that green, living plants can generate electricity. It may seem unbelievable, but not impossible.

One must be wondering how this technology works. Well, the answer is quite simple; photosynthesis. Plants excrete organic matter into the soil as a result of photosynthesis. Only some of the organic matter is used by plants and the rest is released in the soil. This released organic matter is broken down by bacteria. In the breakdown process, electrons are released as a waste product. Since the movement of electrons produces electricity, these electrons, which are of no use to the plant, can be harvested. The best part about this innovation is that the plants from which energy is being generated are not affected in any way.

This idea was first put into use by a Dutch start-up called Plant-e. This company was launched in September 2009 and is successful in launching and selling many environment- friendly products like DIY kits to the public for experimentation purposes and modular systems which could be easily installed on green roofs for abundant electricity production. Plant-e is involved in various projects, within The Netherlands, like automatic lighting systems in gardens and many more.

This technology works with the plants which thrive in moist soils and where the water is present in abundance. Therefore marshlands, paddy fields and deltas are some of the most suitable places for setting up plant batteries as a huge amount of water is present in those areas. Hence, the use of this technology is limited to certain geographic areas containing moist soils and cannot be used in arid regions. It may, however, promote the growth of more trees and plants which will gradually reverse the malicious effects of global warming.

Another obstacle in widespread adoption of this technology in today’s time is the high cost of installation of the system. The initial adopters of this technology are those who are attracted by the efficiency and eco-friendly nature of the plant batteries and willing to pay a premium for it.

The concept of plant batteries can be further taken into rural areas where most of the population still does not have access to adequate electricity. It is estimated that plant-MFC technology can cover upto 20% of European Union’s primary future electricity needs. Also, plants are almost 100% efficient at converting photons from sunlight into electrons which indicates a bright future for this technology. However, more research needs to be done in this field.

Another innovation in the field of green electricity is using algae , which often grows in ponds and rivers, for generating electricity. The basic concept which explains the working is similar to the way plants are able to produce electricity; photosynthesis.

Various other ventures in the field of renewable energy also include vegetable batteries, meaning, electric power generated from fruits and vegetables like lemons, tomatoes and potatoes, have been investigated. According to experiments, at least 3 to 4 vegetables are required just to light a small LED bulb. Moreover, it leads to poisoning of the vegetables and those food products need to be thrown away, without being useful for consumption purposes. It is therefore not a viable option for energy production.

Plant based electricity generation is still an evolving technology which has immense potential for producing energy in an environmentally sustainable way. It will realise full potential when the installation cost is attractive enough for the farmers to prefer it over the electricity grids or fossil fuel based personal electricity generator sets.
