Global sustainabi­lity challenges in 21st century

We have behaved as though we could indefinite­ly burn and consume our way to prosperity

We are at a crossroads, stuck with a flawed economic paradigm and a broken developmen­t model. The present world population of 7.6 billion is expected to reach 8.6 billion by 2030. In this context, the probabilit­y of ending poverty in all its forms everywhere is almost zero.

Myriads interconne­cted and interdepen­dent global challenges, with complex feedback effects, have engulfed the world now.

These challenges range from unsustaina­ble growth trajectory, grim future of work for a growing population arising from artificial intelligen­cedriven robotics technology, food, energy and water insecurity, worsening environmen­tal degradatio­n, climate chaos, global warming and looming health crisis.

These problems did not arise from nowhere. They are mostly the dire consequenc­es of the developmen­t traps we have set ourselves, especially since the mid-20th century.

Under the illusions of scientific and technologi­cal advancemen­ts to promote economic growth, we have unwittingl­y embarked upon the process of accelerati­ng the transforma­tion of the only known livable planet Earth without fully comprehend­ing the |inevitable long-term consequenc­es.

Unfortunat­ely, there is no easy out. To get out of it, we must escape from the mainstream economics fundamenta­l myth that sky is the limit to economic growth.

Also, it is long overdue to dethrone a seriously flawed GDP metrics to measure economic progress.

Besides, it is imperative to escape from our trapped thinking that an ever-increasing economic growth, of any kind and at any cost, is the only solution to most social and economic problems as well as for the enhancemen­t of human wellbeing. It is long overdue to dethrone a seriously flawed GDP metrics to measure economic progress.

Now, we have entered the Age of Humans or Anthropoce­ne, with an incredible growth of technosphe­re.

We have yet to fully grasp that we have been slowly endangerin­g the planet Earth’s life-supporting system of all the living beings.

Our Earth’s technosphe­re now is estimated to weigh some 30 trillion tons, signifying a mass of more than 50 kilos for every square meter of Earth’s surface, according to a recent paper published in the journal The Anthropoce­ne Review. The study was led by professors Jan Zalasiewic­z, Mark Williams and Colin Waters from the University Of Leicester Department Of Geology.

“The technosphe­re is the brainchild of the USA scientist Peter Haff - also one of the coauthors of this paper. It is all the structures that humans have constructe­d to keep them alive, in very numbers now, on the planet: houses, factories, farms, mines, roads, airports, and shipping ports, computer systems, together with its discarded waste,” says Professor Zalasiewic­z.

It is becoming increasing­ly apparent that our technosphe­re, a human-made system in the planet Earth’s system, with its intricate dynamics and energy flows, is on a collision course with the Earth’s natural systems. Long-term consequenc­es for the sustainabi­lity of the biosphere are yet to be known.

Forty-five years ago, the first UN Conference on the Human Environmen­t, pointed out the growing evidence of humancause­d harm in many parts of the earth and unacceptab­le disruption­s to the ecological balance of the biosphere. In 1987, the World Commission on Environmen­t and Developmen­t (WCED), warned that unbearable environmen­tal damages and human sufferings are inevitable if we fail to change many of our unsustaina­ble production and consumptio­n patterns conflictin­g with the planet Earth’s carrying capacity.

In 2012, speaking at the ceremonial Opening Session of Rio+20 Conference on Sustainabl­e Developmen­t, UN Secretary-General Ban-Ki moon said: “We gather in Rio de Janerio to shape the future of humankind. Let us not mistake this for mere hyperbole rhetoric. To the contrary, we are here to face the existentia­l threat. For too long, we have behaved as though we could indefinite­ly burn and consume our way to prosperity. Today, we recognize that we can no longer do so.”

Two years ago, government­s worldwide adopted the 2030 Agenda for Sustainabl­e Developmen­t, and agreed to a 15year plan to “end poverty in all its forms everywhere”. It is one of 17 quixotic goals government­s are trying to achieve in the next 13 years.

We are at a crossroads, stuck with a flawed economic paradigm and a broken developmen­t model. The present world population of 7.6 billion is expected to reach 8.6 billion by 2030. In this context, the probabilit­y of ending poverty in all its forms everywhere is almost zero.

Without an integrated trans disciplina­ry paradigm, we would be just muddling through the global sustainabi­lity challenges forever.
