Is deforestation a necessary evil? Part 2

Back in 2010, there was a huge amount of hype surrounding the finale of the TV series Lost and I would like to think this final post offers a similar amount of suspense in drawing together all the loose ends, questions and arguments formed throughout the past three months in order to answer the important question - is deforestation a necessary evil?
In the second part of this post I will be exploring why we should be stopping deforestation/why are the trees important? and whether we can achieve such as thing  as "sustainable deforestation"? Once again, I will be drawing upon past blogs as well as new academic literature.

I would love to hear your opinion - you can comment on the post or vote in the POLL at the top left of the blog.

Why We Should Stop Deforestation?
From the dark Gothic forests rolling across Siberia to the Kapok trees with their mighty buttresses in Amazonia, trees provide an irreplaceable beauty  that is destroyed by deforestation. No academic study can quantify (or qualify) the uniqueness and brilliance of the natural world held within the planet's forests.
With 70% of the world's land species living in forest biomes, deforestation is an ecological threat. Many of the world's endangered species are threatened with habitat loss due to deforestation:

• The Javan Rhino has been reduced to 60 left in the wild because of the conversion of natural forest to farmland (Fernando et al. 2006).
• Bornean Orangutan is critically endangered due to habitat destruction caused by illegal logging (Curran et al. 2004).
• Golden Lion Tamarin is endemic to the Amazon jungle but is endangered due to agriculture and logging (Keirulff and Rylunds 2003).

Furthermore, as I have mentioned already the natural and the anthropogenic world are consistently interlinked and the destruction of forests would have more than an environmental/ecologically impact but also a human one. Plants and animals provide food, medicine and fuel for indigenous communities and less developed nations around the world and removing this vital resource would limit economic growth (Butler 2012). However, as I pointed out with the case study of Madagascar sometimes local communities exploit the rainforest as much as the developed world to the extent that they see the forest as a source of income rather than a resource to be appreciated. 25% of global medicines are derived from plants found in the world's forests (Kirkman 2014). What would happen if these were no longer available? What about medicines for diseases we have yet to discover?

From a purely ecological/environmental perspective deforestation is dark and evil like the ace of spades. It degrades the environment irreversibly and results in the extinction of priceless plants and animals. However, Part 1 showed that deforestation is crucial for human survival so can we reach a compromise?

Can We Achieve "Sustainable Deforestation"?

David Horsey's "Environment and Climate" cartoons sum up environmental politics nicely (source)

The world watched the COP21 in eager anticipation to see what world leaders would do to tackle global environmental change. There was a pleasing emphasis on deforestation with many countries such as Brazil pledging to reduce net deforestation to 0 under the REDD+ initiative and 42 companies pledging to be sustainable with regards to deforestation.
However, there are real questions about whether this can be achieved or are we heading for a "tree apocalypse"?
I have talked extensively about corruption and problems with political motivation in Brazil and Indonesia but it also goes down to a smaller bureaucratic level. Particularly in developing countries, departments concerned with forestry, agriculture, water, town planning and land use fail to interact ad often work in isolation with a detrimental effect on the environment as each pursues their own aims. Bawar and Siedler (2015) found this to be the case in the Eastern Himalayas where forest conservationist, land-use departments and small-holder farmers failed to interact to address problems associated with deforestation. What about developed nations? How do we manage the bureaucracy and political motivations there? However, education is key in many respects, as illustrated in the Madagascar case study (Dauvergne 1994). Showing local people, as well as governments, the value in preserving forests and the detrimental effects that will happen if deforestation continues  is effective if you show how their actions will adversity effect their lives, and the lives of their children.
Furthermore, a focus on development goals, infrastructural improvements and improving quality of life within countries such as Brazil or Indonesia has put environmental issues on the sideline, in the case of Brazil increased them (Ferraira et al.2014). This paper in Science noted how Brazil's natural resource extraction had increased due to development/urbanization and their growing economy.
We can never fully replace the trees that we have already chopped down, but afforestation and reforestation (discussed on this blog post quite extensively) offers a way to partially restore habitats as well as continue to provide a carbon sink and mitigate against climate change. However, a solution such as this would only be effective if all countries where to monitor deforestation (something that is arguably hard to do) and plant trees to replace the ones that had been felled.

A Conclusion
So that I don't loose track of my conclusions I am going to display them as concise points:

• Whether we like it or not, humans require natural resources (such as wood) to grow and survive and maintain a quality of life that we take for granted. 
• Indigenous people have a right to fell trees and make a living off the land in which they live but at the same time should be educated on the negative impacts deforestation will have on their community and the world. 
• We must learn from the mistakes of past societies (e.g. the Maya) so that we don't repeat them. Although our considerable technological advancements would mean total societal collapse due to deforestation is unlikely. 
• Illegal logging and deforestation is very wrong and tougher penalties should be enforced on those that do not abide by the law. 
• As individuals we can purchase environmentally sustainable products so as not to fuel illegal or unsustainable forestry practices. 
• Deforestation practices need to be altered in order to meet a growing population or population policies must be implemented in order to ensure we have an adequate amount of natural resources. 
• Deforestation can be managed and mitigated in a way that saves endangered species and precious habitats but also provides humans with a source of wood. 
• Deforestation is not a necessary evil but wood is a necessity that humans require. Deforestation is a means by which we get this necessity. However, it can be undertaken in a more environmentally friendly way. We can manage and not waste the natural resources we have at our disposal (e.g. slash and burn methods are extremely wasteful or plant fast growing trees that we can then cut down). 

Deforestation is a complicated topic that has been explored within this blog. It is implicated within sensitive issues (e.g. population) and complicated ones (e.g. politics) but it is a very real environmental problem that needs addressing. I will also post the results of the Twitter Poll ("Is deforestation a necessary evil?") once it has closed in 17 hours time. The poll on the side of this blog is open until noon on the 13th January so keep voting!

Thanks to everyone who has commented and read this blog over the past few months. I hope you have enjoyed reading it as much as I have enjoyed writing and investigating deforestation.

Afforestation - a viable solution to the deforestation crisis?

In the majority of previous posts within this blog the word "afforestation" has been thrown around as a potential solution to deforestation. It has crept up in the comments section time after time and in this latest blog post I plan to explore what afforestation actually is, does it work and its impact on the deforestation discourse.

Afforestation  - the planting of trees on non-tree land. It is different from reforestation which refers to the planting of trees on land that previously contained trees. The difference between afforestation and reforestation varies between definition but general concerns the amount of time that has undergone before a portion of land is considered "non-tree" (IPCC).

Afforestation and Global Climate Change
It is well known that the mighty oaks and little saplings act as a major carbon sink for planet Earth removing 3 billion tonnes of carbon each year (Canadell and Raupuch 2008). Therefore, it is vital deforested trees are replaced. Carbon dioxide released through the burning of fossil fuels worldwide is taken up by plants through the process of photosynthesis.

Whilst Canadell and Raupuch praise afforestation/reforestation processes as a solution to the global climate crisis, Bonan (2008) notes a major limit of boreal forest afforestation techniques.They have a positive feedback mechanism due to a low albedo and therefore create a warming process.

Limitations of Afforestation Practices
The main issue that is thrown around in the media is that managed reforestation and afforestation techniques will not restore the same biodiversity of the original forest. In an incredibly dated account by Stirling-Maxwell (1917) he describes the detrimental effects afforestation practices have on the environment. A devote critic of afforestation it appears, he talks about how different types of forest distinguish different regions of the world and that afforestation makes the environment more homogeneous (this opens up a whole new bag of worms surrounding "a flat world" and "the end of geography" - see the works of David Harvey and Doreen Massey). Whilst this may be true to some extent because the land is never fully returned to its original state, the same limitation of homogeneity can be applied to deforestation and Stirling-Maxwell (1917) offers no opinion on that. Wallace and Good's (1995) research into the North East of England supports Stirling-Maxwell's account of afforestation in that afforestation leads to a single more dominant species with other co-existing vegetation not being replaced.
However, Day et al. (2010) looked into afforestation on agriculture in Eastern America and noted that vegetation complementary to the dominant species (in this case oak) was grown as well to increase biodiversity. The research showed that because the seedlings and trees required consistent management for survival and growth that it was only realistic on a small scale.
The effects of afforestation vary between locations and are dependent on the techniques employed.

The Green Wall of China
Most of China's trees have been destroyed, devoured by the imperial juggernaut of urbanization, pollution and babies. The Chinese government set targets for the next 80 years but as of 2008 had made no progress in meeting them. With the help of Shanghai Roots and Shoots, a division of the Jane Goodall Institute, a total of 1 million trees have been planted to date to stop the expansion of the Gobi Desert.
China's problems do not stop there, however, as the detrimental impacts of non-native species is starting to have an effect with the non-native species removing excessive amounts of the water from groundwater causing the water table to be reduced (Window of China News)
Lets put this in perspective though - the Trees for the Future foundation has planted 35 million trees worldwide whilst the Green Belt Movement in Kenya has planted 47 million trees.

Is Afforestation a viable solution to our deforestation problems?
This blog post is clearly summative in its analysis of the major limitations and benefits of afforestation/reforestation with whole books dedicated to just the biodviersity impacts of these techniques. Afforestation, like most solutions, is not without its limitations. Taking away productive land from other sectors such as food production and housing for trees is clearly an issue with much debate surrounding it as we constantly fight for space. Other than reducing deforestation (a post about deforestation, policy and politics is on the horizon) afforestation and reforestation is one of the most viable and popular solutions to deforestation. Furthermore, significant afforestation could have a noticeable impact on our climate system that may have beneficial impacts on climate change - although research into this is vague and poorly understood. I see afforestation and reforestation techniques as a policy that most governments should implement on some level - Brazil's afforestation policies is shocking! - because the benefits outweigh its limitations.
