Environmental impacts of coronavirus crisis


The United Nations conference on Trade and Development (UNCTAD) noted that As the number of coronavirus infections grew exponentially in Europe and North America in March, restrictive public health measures to stave off a worsening pandemic were put in place.

They included stay-at-home orders, which were first issued in Italy and then in rapid succession in most other countries around the world. With entire populations ordered to stay home, schools, offices and factories limited their activities, road traffic dwindled to a minimum and airlines reduced scheduled flights by 60% to 95%.

The followings are the immediate effects on the environment:
Slashed greenhouse emissions
While consumption and employment levels dropped precipitously, they have also been associated with significant reductions in air pollution and greenhouse gas emissions. As a result, air quality levels in the world’s major cities improved dramatically in March and April. Air quality improved largely because of a reduction in factory and road traffic emissions of carbon dioxide (CO2), nitrogen oxides (NOx) and related ozone (O3) formation, and particulate matter (PM).

During the same period, global air traffic dropped by 60%. Taken together, these emissions reductions have led to a temporary dip in CO2 emissions from their pre-crisis levels, encouraging some to hope that our global society may indeed be able to reduce greenhouse gas emissions substantially over the long term to mitigate impending climate change. Obviously, there are many challenges ahead.

Not all positive
But not all the environmental consequences of the crisis have been positive. Volumes of unrecyclable waste have risen; severe cuts in agricultural and fishery export levels have led to the generation of large quantities of organic waste; maintenance and monitoring of natural ecosystems have been temporarily halted; and tourism activity to natural areas has ceased.

Local waste problems have emerged as many municipalities have suspended their recycling activities over fears of virus propagation in recycling centres. Food retailers have resumed using plastic bags at checkout points citing health concerns over consumers’ reuse of paper bags. In addition, due to stay-at-home policies, many consumers have increased their consumption of take-away food delivered with single-use packaging.

All these developments have created acute challenges for the waste management industry at a time when they are operating with limited capacity due to the coronavirus crisis.

Ecosystems at risk
Natural ecosystems and protected species are at risk during the coronavirus crisis. In many countries, environmental protection workers at national parks and land and marine conservation zones are required to stay at home in lockdown, leaving these areas unmonitored. Their absence has resulted in a rise of illegal deforestation, fishing and wildlife hunting.

Many of the environmental challenges caused by the coronavirus crisis will gradually resolve on their own once the crisis comes to an end and previous levels of economic activity resume. Unfortunately, it is also true that the benefits of air pollution reductions will also be erased. Overall, the crisis may thus have no permanent environmental effects.

However, what we have learned about the environmental benefits and risks of sharp drops in global economic activity will certainly help us to better understand the mechanics of environmental sustainability, societal consumption patterns, and how we can reduce environmental degradation in a future crisis-free world.

Need for action
Attention must be given to threats on the environment and natural resource bases as a result of the coronavirus pandemic and consequential social and economic impacts.

While helping all vested parties to adapt to crisis market conditions and take actions for recovery is seen as a top priority by many authorities, governments should empower the environmentalists and scientists together to work out plans and schedules to protect the environment.
