When one first meet the expression Doughnut Economics, he may think of a joke, or perhaps an economic model for managing the supply or the purchase of food. It is not the case! The Doughnut Economic Model proposed by Kate Raworth is a very deep, at the same time philosophic and pragmatic, approach towards the matter of sustainable economy. Thinking that there are 2 lines, 2 limits, 2 boundaries, that, when overpassed, could trigger a serious of nefarious things for human development is very valuable and of practical use for citizens, academics, firms and institutions. Kate Raworth, in her book Doughnut Economics, Seven Ways to Think Like a 21st Century Economis, explains clearly the basics for sustainable development.
Climate Change has given birth to a big, global debate over the past 30-40 years. Although the scientific community, thanks to the numerous reports by the IPCC (Intergovernmental Panel on Climate Change), agrees on the facts that 1) climate change exists, 2) climate change is caused by anthropogenic factors (by humans), 3) Climate change over the last 200 years has accelerated considerably (it is estimated that Cliamate Change is 170 times faster than in pre-industrial times), there are still people who deny these statements; they claims that climate change is natural and we cannot do anything to change the course of events. This article proposes an analysis of the three major measures (consequences/results) of Climate Change (CO2 concentration in the atmosphere, Global temperature, Arctic ice extent). It’s interesting to note that these three measures converge in one direction: Earth moves towards overheating with tight rhythms.
In the 20s, Prof. Simon Kuznet created a measure of the value produced by a single country in a specific year: the Gross Domestic Product (The GDP). Being at the end of the Second Industrial Revolution, and still having much to gain in terms of “material wellness,” the GDP proved to be very useful to measure the development of a Country. Since then the growth of GDP has been the main mission of almost every Country in the world. But now that we are overexploiting our planet and that, at least for some Countries, material wellbeing is too excessive, we need another index, which will help us to put our impact (our footprint) on the environment into control. Increasing GDP is no longer the priority.
As much significant as worrying this indicator, the Fishing Dependence Day, which this year fell on 31st March. In other words, in just three months, we have eaten as much fish as Italy (within its basins) can produce (catch) in a year. This means that Italy produces just 25% of the fish its citizens consume. It is not self-sufficient in terms of fishing! However, it is not just the single data to worry…It is the trend! Italy self-sufficiency in terms of fish has dropped from 50% to 25% in the 1990-2015 period. A more sustainable approach is needed both in the fishing industry and in the consumption of fish. Let’s have a look at data and let’s see what can be done so as to make the fishing industry more sustainable.
What happens if the pesticide used to protect the plant from the pest becomes even more dangerous than the parasite itself to human health and the biological heritage of the area. This is the case of “glyphosate,” an element used in many pesticides since 1974, particularly in the USA, but which, according to some studies, could prove toxicity for the environment and detrimental to health.
