Tree planting is capturing the minds of those who look for fast climate action. Earlier this month, the Ethiopian Government announced a new world record: thousands of volunteers planted 353 million trees in one single day. This came shortly after a team of scientists identified suitable places in the world where up to 1 trillion new trees could be planted. Such a massive effort could absorb about 20 years’ worth of global greenhouse gas emissions. And on 8 August 2019, the Intergovernmental Panel on Climate Change launched a Special Report on the importance of land use for the climate. About 23 per cent of all emissions come from the agriculture, land use and forest sector. The Intergovernmental Panel on Climate Change outlines land management opportunities with benefits for food security, biodiversity, and the climate, such as agroforestry.

The growing enthusiasm for forests and trees is a good thing. Ecosystem restoration will be critical in turning the tide against climate change, and achieving the Sustainable Development Goals. But we need to be mindful of some pitfalls lurking along the way. We have learned valuable lessons over the past decades in afforestation and other restoration projects across dozens of countries. A few basic principles outlined by the Global Partnership on Forest and Landscape Restoration can help us to reduce costs and minimize future risk as the world embraces the need to plant more trees.

Stop the bleeding

The first rule for ecosystem restoration is to stop the further destruction of forests, wetlands, and other critical ‘green infrastructure’. Conserving natural habitats is always cheaper than restoring it later.

Most new trees do not need to be planted

Most ecosystems in the world have remnant seeds in the soil and natural regrowth can be cheaper and more successful than tree planting. The most cost-effective type of restoration is to work with the forces of nature. For example, across the Sahel, a successful and fast landscape restoration technique is called ‘farmer-managed natural regeneration’. It uses the existence of remnant root stocks below the surface, where the trees above ground have disappeared long ago. Farmers nurture those roots and trees back to life. The results are stunning—within a few years, large trees dot the surface of the once barren and dry savannah, bringing back water, productivity and life.

We don’t need to reinvent the wheel

There is already an impressive body of knowledge on which trees to plant, when and where. Under the Bonn Challenge, a global restoration goal initiated by the International Union for Conservation of Nature and the Government of Germany, 59 governments, private associations and other entities have pledged to bring 170 million hectares into restoration by 2020, and 350 million by 2030. Dozens of countries have already detailed maps of where the best restoration opportunities can be found, and how to restore forests and landscapes. Usually, indigenous tree species are preferable, but in a rapidly changing climate, we need to keep in mind that the natural ranges of trees are shifting.

Social inclusion is essential

Forest and landscape restoration is mostly about social transformation, rather than technological solutions. However, this transformation is hard work and requires patience. It is tempting to just stick a few tree seedlings in the ground and hope for the best, but real restoration across an entire landscape is the work of years or even decades. Large-scale restoration successes such as the Shinyanga landscape in Tanzania or the Loess Plateau in China have shown that results of well-planned restoration can yield very high returns for society over a long time.

We must remove the bottlenecks

Some ingredients for success are essential, and their availability varies across countries. The most important one is political will. Fortunately, political will is now growing as protests for more climate action are spreading.  Another major ingredient is clarity over ownership and management rights. The estimated 1 billion smallholder farmers in the world will be key. We need to empower them, and give them access to the tools and the finance for improved farming, such as agroforestry. A third key ingredient is availability of a variety of high-quality tree seedlings, in particular for planting trees on farms.

Finally, perhaps the most critical ingredient are massive public and private investments into land restoration. We need to achieve a similar trajectory for a shift in agriculture and forestry as is happening in renewable energy. And just like the shift in renewables, it will take a massive push from both public and private actors to establish restoration as a new financial asset class. It is estimated that every dollar invested in ecosystem restoration can yield more than US$10 in return through ecosystem services. Fortunately, we see growing interest from the finance industry to invest in ecosystem restoration and regenerative agriculture.

Ecosystem restoration and other nature-based climate solutions will be highlighted at the UN Climate Action Summit on 23 September. And the UN General Assembly has just proclaimed a UN Decade on Ecosystem Restoration from 2021 to 2030. With the right approach, we can make the conservation and restoration of ecosystems, including the planting of billions of new trees, a major step in building the sustainable future we all want.

Climate Change Problem: an Emerging Threat to Global Security

Published

on

Climate Change is one of the greatest challenges faced by humanity. The Greenhouse–gas emissions and over-exploitation of natural resources result in a rise in temperature which brings floods, droughts, a rise in sea level, and other destructive events. The problem is that climate change is a global bad, and it requires collective efforts and cooperation to limit its effects. One state cannot control Climate change alone because it does not take it into borders. Formally, the climate change issue was a matter of low politics, but the inception of the 21st century brought an understanding that it poses greater threats than traditional ones. The Covid-19 plays a major role in the realization of steps taken towards climate cooperation. States often make climate promises but cannot fulfill these promises because of the fascination with development and ignore climate change. But now world leaders have realized that the lessons of COVID-19 can tackle global climate change problems otherwise it will make this world difficult to live in.

 The newly elected President of the United States (US) Joe Biden inaugurated a virtual climate change summit with 42 world leaders. It includes leaders from Russia, China, Turkey, Israel, India, Bhutan, Bangladesh, and Pakistan. Setting aside all the differences, he invited leaders from those countries that are a major contributor to Greenhouse gas emission and those who are most vulnerable to climate change risk. In this summit, the Biden administration asked the world leaders to take actions to combat climate change collectively as the climate is a global good and requires collective efforts to tackle climate change. Biden has announced an aggressive new goal policy for greenhouse gas emissions. 2030 committed the US administration to reduce its greenhouse gas emission to 50-53%. The National Intelligence Director of President Avril Haines told world leaders that the climate change issue is no longer remains a peripheral issue but at the center of foreign policy. Other states such as France and Russia also promised to limit their greenhouse gas emission to 42-46% by 2030. It also committed China to play its role in the summit by announcing its willingness towards coal reduction. India reiterated its target of 450 GW of non-renewable energy by 2030 and announced to launch the “US-India 2030 Climate and Clean energy Agenda 2030 Partnership”. The Brazilian Environment Minister argued they need funds to enforce their plan to eliminate deforestation and carbon emission from their country. Vice president Harris argued that climate actions are necessary to tackle climate crises and to promote job opportunities. . Now, the US has put climate change at the center of its security and foreign policy because climate change is not only changing the pattern of the environment but it speeds up the geopolitical competition, undermine security and provoking ethnic conflicts. The climate change results in cyclones, floods, the rising temperature that disrupts social and economic conditions that threaten food security and human security.

By exploring the climate solution, the virtual summit announced the need to increase the public finance for mitigation and adaptation in developing countries. Biden emphasized the importance of investment in the public and private sectors to achieve the collective goal of net zero-emission. Further, climate actions require cooperation at the national and sub-national governments to speed up efforts to transform communities in line with limiting warming to 1.5 degrees Celsius. Another change that needs to be highlighted at the national level is that the government must not subsidize renewable energy industries and keep their prices high to contain their over-exploitation.  It is easy to make promises as states do, but the problems emerge in its implementation. For decades, climate change has raised concern but states often prioritize development over the environment. This is real-time for states to limit their emission and comply with the promises they have made in the summit otherwise it will lead to never-ended consequences.

COVID-19, a super-fast placed event that emerged from one part of the world and quickly spread throughout the entire world. By its speed of diffusion, it reduced all the emissions at an expensive cost, thus halting the global economy. So still we have time to think about other efficient means of emission reductions to prevent countries from the intolerable burden of Climate Change. But the challenge is how to keep that emission reduction after the pandemic. Second, just an as sharp and instant change of behavior is possible with COVID-19 so to deal with climate change a behavior change is also possible, thus shifting to the low carbon emission all depends on seriousness and credibility to the mortal threat. Third, a key implication of COVID-19 to climate change is that how to reorganize the economy so, in the post-pandemic world, it is the human interaction that would determine the organization of the economy. Thus future will determine whether a low contact economy with a clean environment would be a lower carbon emission economy or not. Further, states must focus on how to open up the economy in the Green Revolution. Another major issue which the world leaders failed to address is the global problem of Covid-19. Despite the technological advancement and huge development, zoom diplomacy began with a distorted voice from the most advanced countries of the world. There is a need to cooperate on a matter of Covid-19 so that states think on the wider notion of climate actions. Thus we have to use all these lessons in the context of climate change to make this world a better place to live in.

Rails, Roads And Emissions

Published

on

It is common knowledge that emissions affecting climate are least for rail travel in comparison with airplanes or road vehicles.  Consequently the $80 billion allocated to rail in an otherwise laudable budget appears paltry. 

Why is the US not investing in rail?  The usual reason given is that distances are so vast that it’s a no-brainer for business travellers to rely on commercial airlines.  But the way the technology is advancing, and as Europeans (and the Chinese) have demonstrated, a network of high-speed rail can offer a greener alternative. 

Trains are getting faster and new innovations like tilting trains lower the cost of replacement tracks.  If 200 mph is being breached more often, then 250 mph should be in our sights.  And Elon Musk has proposed vacuum tubes to remove wind resistance and reach even higher speeds. 

Yet a 250 mph rail network with average speeds in excess of 200 mph would revolutionize the concept of travel.  New York to Chicago in five hours and east to west coast overnight with the possibility of visiting neglected areas out of reach with expressways and airplanes would bring new growth and dynamism where it is needed. 

A point to note is prevailing interest rates.  They are so low historically that railroad bonds at a competitive interest rate would be snapped up  especially if they were guaranteed by the government. 

While one can agree with the aims and compassion clearly evident in the president’s proposals, the process to achieve them is less clear.  In particular on climate change the goal of net zero emissions within a decade is laudable.  But a speedy switchover to electric vehicles raises questions: Simply, how?

The system is geared to internal combustion engines.  Mechanics train for years to become proficient.  Aside from that, has anyone wondered what happens to all those large electric car batteries when they have to be replaced?  Since lithium used in them is a finite resource, it would have to be recovered or the 80 million tons estimated to be the world’s store would eventually be depleted.  

Another issue is the electricity used to charge the batteries.  If it comes from a coal-fired plant, are we back to square one?  Currently about a quarter of the electricity generated in the US comes from coal. Of course dealing with pollution at the source (like a coal plant) is easier. 

The number of Americans living paycheck to paycheck (roughly half) is just one more reason the changeover to electric vehicles might take a while; they just don’t have the funds.  Add to these numbers the elderly living on fixed incomes or the ranks of the unemployed and one can understand the scale of the problem.  

One can laud the US president’s goals but we need to see some action (even proposals) to facilitate them.

Global Environmental Governance and Biden’s Administration

Published

on

Being the largest emitter of greenhouse gas in the world, it is the responsibility of U.S to contribute expeditiously to manage the environmental issues at domestic and international level but the previous government, under the leadership of Trump, took back seat and reversed all the decisions of Ex-president Barack Obama to combat the climate change. Unlike this, New Elected President, Joe Biden, who is very enthusiastic and firm to fulfill all the promises regarding climate change which were done during the general election’s campaign. Moreover, he views climate change a thwart to national security. One of the biggest achievements associated with Biden’ administration regarding environmental issues is to bring U.S back into Paris Climate Accord and brought executive order’’ Protecting Public Health and the Environment and Restoring science to tackle the climate crisis’’ on the surface.

A flurry of changes to U.S environment policy is going to play a constructive role in global environmental governance under Biden administration. Even before elections, climate change was one of the top priorities and aimed to put the U.S on a path which leads towards ‘’ Zero Net’’ greenhouse gas emission. In the very early of His office days, He is very committed to deal with the climate change as they hosted ‘’ Climate Day’’ to introduce government climate centric approach to emphasize on the climate change.  Biden administration also ordered to revoke a permanent issued for Keystone XL oil pipeline which trump issued for extraction of oil and energy which is dangerous to national ecosystem. In addition to this, they are also very active to promote US role to tackle the climate change at domestic and abroad. At domestic level, Biden’s actions are speaking louder than the words as he has ascribed the climate crisis with a national emergency. At the time of his inauguration, Biden said: ‘’ A cry for survival comes from the planet itself, a cry that can’t be any more desperate or any clearer’’. He also directed his cabinet to work on the policy of ‘’ social carbon cost’’ to measure the cost of actions and how costs will impact the climate change. He endeavors to control the climate change by keeping a strict eye on the big project’s reviewing process before working under the National Environmental Policy Act which calculates the social costs of greenhouse gas emissions.

On international level, Biden has been striving to improve the spoil image shaped by the previous government regarding global environmental governance as he has declared to rejoin the Paris Climate accord which would help to reduce the greenhouse gas emission. In the result of this action, Biden was welcomed by the General Secretary of the United Nations and French Prime Minister Emmanuel Macron by saying ‘’ Welcome Back to the Paris Agreement’’. Moreover, Biden Administration is very determined to convene a global climate summit on the earth day to encourage leaders to align themselves with scientist to alleviate the impacts of climate change. On international forums, US need to cooperate and compel the economic trade partner to take actions to combat with climate crisis. One of the essential steps taken by the Biden administration is to manage the climate refugees which aim to make strategies to compensate the climate affected migrants.

The thin majority of democratic in the senate does not only limit the possibility for Biden to achieve climate change reforms along strong anti-climate lobbyist business group who are inimical to the reforms particularly relevant to vehicle, power plants and oil and gas drilling industries. Without new climate legislation from congress, it would be not an easy task to implement the climate agenda across the borders. The vocal resistance comes from the coal production sectors which result in burning of fossil fuels and caused of greenhouse gas emissions. Whereas, few sectors are opposing the agenda there are also companies specially electrical vehicles are exclusively offering assistance to Biden for the sustainable development. Undoubtedly, environmental organizations and scientists community applauded the Biden decisions but few business groups have also filed a lawsuit against Biden to not stop the new permit for oil and gas drilling. There are also concerned raised by the community that climate actions will delete many jobs and cause of upsurge in unemployment percentage across the federation.

It is very evident from the ambitions of Biden’s action regarding climate crisis that he is very interesting to mitigate and curb the climate change but it will require highly comprehensive strategy aims to manage the reforms in laws while taking congressmen in confidence because most of them are not in favor of climate actions due to clash of interests. On the other hand, there is need to work on renewable energy resources at domestic and international level and for this US should compensate the companies to compete with the old capitalized firms which do not want safe and peaceful planet. Moreover, there is need to bring reforms in existing environmental treaties and their compliance process which should be strictly followed by the harsh actions against the violators. The process of financing the agendas which are very environment friendly and transforming the resources to the periphery states should be done swiftly to improve the environment across the globe. The aims of achieving sustainable development should be promoted and supported by the US across the world.
