“Cotton can be grown using a wide range of cultivation practices determined by climate, soil type, availability of inputs, and possibly most importantly, the knowledge and skills of the farmer.” (The Sustainability of Cotton: consequences for man and environment) The most common systems used in cotton cultivation are conventional, organic, and integrated pest management (IPM). The three systems used in cotton cultivation all engage in applications that are unsustainable for the environment. The Sustainability of Cotton: consequences for man and environment report the following problems in sustainability related to cotton cultivation:
- degraded land as result of salinization and erosion
- water depletion by excessive use of soil and surface water
- natural habitat conversion due to cutting of forests and dam constructions
- eutrophication of surface water
- wildlife contamination by pesticides
- human health due to direct pesticide intake
The irrigation phase of cotton cultivation has significant environmental impacts. The irrigation used for large scale cultivation projects most commonly utilized in the United States, manipulate excessive amounts of water unsustainably. The excessive amounts of water used in the cultivation of cotton has contributed to water shortages that directly impact wildlife and humans. Soil salinization also arises due to land being degrading during the irrigation phase of cotton cultivation. The Aral Sea, is a wonderful example that accurately conveys the detrimental impacts that can result due to excessive water use. At one time the Aral Sea area was the one of the biggest cotton providers for the USSR. The overuse of water has contributed to the Aral Sea experiencing a huge decline in sea area levels, fish and plant species, and the fishing industry. In the United States the High Plains Ogallala aquifer is rapidly becoming the modern day Aral Sea. This aquifer provides water to the majority of the cotton crops that are cultivated in the southern portions of the United States. However, the High Plains Ogallala aquifer is estimated to be “8 times faster than nature is replenishing.” This abuse will not cease until the necessary measures are taken to refine the process of cotton cultivation.
Organic and synthetic fertilizers are used in the cotton cultivation process. The ingredients such as nitrate and phosphorous, commonly found in synthetic fertilizers, easily bind to surfaces, groundwater, and sediments. Ultimately this contributes to eutrophication, which has a “devastating effect on aquatic ecosystems leading to, for example, algae growth, depletion of oxygen and a decline in aquatic plants and animals.” (The Sustainability of Cotton: consequences for man and environment) The usage of synthetic fertilizers in the cultivation of cotton also contributes to global warming. Similar to fertilizers, the application of pesticides in cotton cultivation have highly unsustainable impacts on the environment and humans. The Sustainability of Cotton: consequences for man and environment addresses the “pesticide use in cotton cultivation in developing countries is high: about 50% of pesticides are used in cotton cultivation and the types of pesticides used tend to be highly toxic and, although several developed countries.” It’s also reported “in developing countries much conventional farming is far from sustainable, with demonstrated heavy pesticide impacts on the environment and on people.” Many developing countries are devoted participants in the cultivation of cotton and these regions are the most susceptible to experiencing a larger amount of inequalities and disparities compared to developed countries. The workers in developing countries lack the knowledge and awareness to comprehend the negative side effects associated with the application of pesticides. In addition to the harmful impacts pesticides have on human, they’re also very harmful to the environment. The majority of the environmental damages caused by pesticides are unintentional and often result from poor management practices. “It is estimated that pesticides unintentionally kill 67 million birds each year.”(The Sustainability of Cotton: consequences for man and environment) In Pakistan and Shukla, the groundwater is now contaminated due to the constant use of pesticides in cotton cultivation.
Deforestation often occurs to provide more land specifically to increase the area allotted in the cultivation of cotton. The environmental impacts of deforestation contributes to the loss of biodiversity, soil erosion, and global warming. The Sustainability of Cotton: consequences for man and environment reports “very large cotton fields existing in the USA and Australia may have significant impact on biodiversity.” Many of the contributors to the unsustainable practices utilized in the cultivation of cotton are motivated by the profitability of this supposed ‘cash crop’ and fail recognize the detrimental impacts that their reaping on the environment. Before reading this article I thought the organic cultivation of cotton had far superior sustainable practices compared to conventionally grown cotton. However, organic and conventional systems each posses a significant amount of unsustainable techniques and practices. For example, “when organic growers apply improper amounts of organic/natural fertilizers or apply them when the crop does not need fertilizer, they contribute to the same unsustainable elements as high input conventional systems.” (The Sustainability of Cotton: consequences for man and environment) All production systems, conventional, organic, and IPM, may use different techniques, but all in some way or another actively engage in cultivating cotton through the usage of unsustainable practices that deplete the environment of its natural resources.
Solutions are being developed in cotton cultivation that are more sustainable for the environment. The video Cotton & Water: white, blue, and green on the Cotton Inc. website gives us hope that in the future cotton will be cultivated using more sustainable farming techniques and practices. Over the past thirty years, many experts have predicted global water shortages to worsen. This has now become a reality and due to the increase of global water shortages more sustainable practices in water conservation are being developed and administered in the cultivation of cotton. Similar reports, from Cotton Inc. and The Sustainability of Cotton: consequences for man and environment, agree that cotton can be cultivated by using less water and the quality will not be sacrificed. Cotton Inc. has begun to implement new procedures to address the unsustainable impacts that cotton cultivation contributes to soil erosion. Conservation tillage is a newly developed method that helps reduce soil erosion. The Sustainability of Cotton: consequence for man and environment also attributes the method of conservation tillage as a promising technique in cotton cultivation to help minimize soil erosion. Conservation tillage protects the soil enabling it to soak up more rainfall and produces more CO2 into the atmosphere. I’m hopeful that further techniques will be developed to ensure more sustainable practices in cotton cultivation.
Hi, Bree! Wow, I can always count on you for an entertaining intro and an exceptionally thorough blog! So, when you boil it all down, do you think the cultivation of cotton is sustainable?
ReplyDeleteThank you Professor Armstrong!
ReplyDeleteNo I think it's very unsustainable and it's mind blowing that many of these unsustainable practices have went centuries going unnoticed. People are realizing that the world doesn't have infinite resources. If only people could've realized this sooner than we wouldn't be in such a serious position. I found the videos on Cotton INC. very informative, this company is truly doing some great things.
Hey, Bree; What do you think was the tipping point? In other words, at one point in time, these practices may not have been an issue, but a number of factors have contributed to significant turn of events just in the last 50 years.
ReplyDeleteYou're right, Cotton, Inc. does a lot to support the cotton industry (not necessarily organic cotton) as well as education. I think it is important to keep in mind that their sole purpose is to sell more cotton, so though they do a lot for that industry, they are not entirely open to "material diversity," and taking pressure off of cotton and on to textile alternatives. We'll look deeper at the stakes that influence perspectives next week!
Dr. Armstrong:
ReplyDeleteThe factors that I think ultimately contributed to the turn of events are mechanization, an increase in cotton yields, intensified levels of consumer consumption, and increasing demand for 'fast fashion' products. One word that truly sums up these four contributing factors is 'demand'. The "I want more" mentality that many consumers possess increased the demand of cotton, thus increasing the practices of cotton cultivation. Great strides towards technological advancements have occurred over the last 50 years and this has simplified the cultivation of cotton making it easier and more accessible. More people participating in production sequentially led to more environmental damages therefore, becoming unmistakably visible to the public. Wow, I never looked at it through that perspective and it really causes me to reconsider classifying Cotton Inc. as one of the "good guys" in this situation!
Hey, Bree -- great response and reflection! Yes, the technology we use (tools) have contributed greatly to this spike in environmental impact. Perhaps, we can create new technology (tools) to lessen it . . . I'm not necessarily saying Cotton, Inc. is not part of the good guys, just pointing out that their perspective is a unique one and it's important for us to scrutinize what influences these perspectives about sustainability when we are determining the truth for ourselves. Great work this week! Keep it up!
ReplyDeleteHi Professor Armstrong-
ReplyDeleteThank you, and I agree with you concerning the importance of looking at a variety of perspectives!
