Deforestation and Drought

The article discusses the global impacts deforestation and logging are having worldwide. It specially discusses the impacts on the water systems and how reduced forest cover can lead to significant drought worldwide. It points out how researchers are developing a deeper understanding of the earth’s changing bioclimate and the vastly complex global interplay between living organisms and climatic forces. In doing this they are able to get a better understanding of the crucial role that deforestation plays. In addition, it discusses how deforestation can affect climate by absorbing more solar energy than grasslands, for example, or releasing vast amounts of water vapor. Many experts believe that deforestation is taking place on such a large scale, especially in South America and that it has already significantly altered the world’s climate even though its dynamics are not well understood. Cutting down forests degrades these low-pressure systems, essentially turning off the pump that moves water, commonly known as “biotic pumping.” Large-scale deforestation is thus believed to be a major contributor to the extreme drought in Brazil. As well, the article also points out the increasing rate at which deforestation and logging are occurring globally.  In the last year alone some 2,000 square miles of the Amazon were lost to clearing, largely for planting soybeans and raising cattle. A growing number of scientists are warning that wide-scale deforestation may already be directing precipitation away from places long accustomed to it (Robbins, 2015).

 

It is clear globally that there are significant issues when it comes to resource management of forests, further leading to significant consequences as the article pointed out such as drought and fluctuations in precipitation. In addressing these issues of resource management, more effective management approaches need to be put into places in areas that experience rapid deforestation and logging. In Canada we have forest management that involves conservation for habitat and biodiversity as well as climate, pest and disease outbreaks. In addition, in Canada we also have the Canadian Boreal Forest Agreement which outlines commitments in maintaining forest resources, some of which include the protection of species, implement sustainable forest management practices and take action to reduce climate change and GHG emissions.  However, areas such as the Amazon that are getting hit the hardest in terms of deforestation, would significantly benefit from better forest management and would significant help in preserving forest resources. Areas such as the Amazon, especially at a local scale, lack necessary management of resource strategies. By implementing more adaptive management strategies focusing on sustainable practices as well as more sustainable extraction rates would helping in reducing the amount of forest resources being lost in the Amazon As well, its also important to consider the rate of regrowth in these areas. As the article points out, tree regrowth is a significant part when it comes to forestry management and needs to be implemented more aggressively if we are to combat climate change.  In addition, implementing something like what the Canadian Boreal Forest Agreement outlines would also help these areas in combating other significant issues, such as endangered species and unsustainable practices.  Community based management would also be beneficial for areas such as the Amazon as it would get communities  involved in combatting the issue.  Providing local insights into the issues will gain a more in depth perspective on the challenges certain areas may face. In addition, it also encourages communities to take action in forestry management by encouraging more sustainable practices, as they rely on the area for their livelihood.

 

In conclusion, areas such as the Amazon need to implement better adaptive management techniques when it comes to forest management and deforestation. The article demonstrated the impacts the amount of deforestation is having on different parts of the world and the future impacts that will occur if the rate of deforestation continues.
