Making the Link: Climate Change, Water Security and Health

Since arriving in India, one of the things which I have been considering is the links between climate change, the water cycle and health. India suffers both extremes of the water cycle: some areas experiencing many drought years, others experience heavy flooding. The apocalyptic photographs of the flooding in Uttarakhand, with a death toll of at least 1000 people, stands in direct contrast for the area of India, the Thar Desert, that I have experienced.

Last Tuesday (2nd July), the UN’s World Meteorological Organisation (WMO) released its climate report on the last decade which exposed the climate extremes that have occurred between 2001 and 2010. The report recorded an ‘unprecedented’ rise in climate pattern which is estimates has resulted in more that has 370,000 deaths due to heat waves, flooding, tropical cyclones and other phenomena. The most notable of these was the 2010 flooding in Pakistan which affected over 2 million people.

However, what I have begun to notice, living and working in a very arid region, is that the WMO figure is really only the tip of the iceberg when it comes to climate-related, specifically water-cycle related, deaths. The real human cost is much higher.

The effects of events such as flooding are immediate and provide a very visual and panoramic spectacle of a climate-related disaster. In these cases, the links between extreme weather events, and their resulting problems, are easy to make; the immediate evidence is hard to deny.

For example, the link between climate change and increases in cases of malnutrition is evident. A low yield of crops after a failed rainfall is causally linked and the evidence is relatively hard to refute. A change in the rainfall, such as a failed monsoon, creates low soil moisture which affects crop yield, in turn causing farmers to have less access to both the food they grow and the food they can afford. This trend is easy to evidence for several reasons: firstly, it happens in a short, controlled time frame and, secondly, the links between drought and fluctuation in climate are correlative. Therefore, the causal link from poor yield to reduced food security is a logical one.

The problem in recording climate-related deaths becomes more difficult in trying to hold to account the deaths in which the causal link is blurred by other variables and, very importantly, takes place over an extended period of time. There are many examples of these seemingly non-climate­ related events. The one I will use is one which has become increasingly apparent to me through my work with GRAVIS: the occurrence of Occupational Lung Disease (OLD).

The causal link between climate change and Occupational Lung Disease could be seen as the following: the event of poor rainfall results in a poor crop yield, which impacts on the ability to feed a household and livestock. Due to this shortfall in food and income, farmers must seek alternate employment. Often this need requires migration.

One of the most common alternative forms of employment in the Thar is mine work. Workers migrate from rural farms to work in sandstone and marble mining, for example the mines near Jodhpur, where they work long days in the blistering heat with no shelter, little water and no toilet facilities. Further to the lack of provisions for basic rights in a workplace, the employers, through ignorance or negligence, do not provide adequate health and safety in the mines to prevent inhalation of the dust through practices such as wet drilling (as opposed to the prevalent and cheaper dry drilling which creates a lot of dust).

This dust contains crystals of silica which lodge themselves in the lungs and accumulate over time. The initial symptoms are irritation and inflammation of lung tissue which then progresses to fibrosis (scarring) of the lung tissue. The effects of silicosis are the collapse of alveolus (airsacs) in the lung, emphysema and a weakened resistance to secondary lung diseases such as tuberculosis. Silicosis limits life-expectancy by an average 15 years and cause early death through respiratory failure and heart disease.

The problem with linking Silicosis and climate change is that it is not as easily correlative as a problem such as malnutrition or a rise in communicable diseases (such as diarrhea diseases) during flooding. The causal link between the two is more complex and runs through many events such as crop failure and migratory patterns. Furthermore, the variability of employer responsibility regarding healthy and safe practices complicates any direct causal link. If the employer took the legal responsibility for mine workers’ health, it would go a long way to mitigate the effects of Silicosis.

However, currently this protection is not happening; therefore, during years of failed rainfall, farmers become forced environmental refugees who are economically dis empowered. They are living a life of subsistence exacerbated by environmental problems. Therefore, they do not have the economic independence to demand better working conditions or the opportunity of alternative employment. They are working for the continued survival of themselves and their families.

The other issue which causes a difficulty in creating a link between climate change and many deaths, such as those arising from Occupational Lung Diseases, is that they occur over a much longer time period. Therefore, unlike many casualties of climate change, the impacts are not as easily and directly demonstrable.  The problem is one which takes place within a slow time-frame, unlike the rapid human impacts of environmental changes seen in disasters such as flooding.

Climate Change is the most fundamental issue facing this planet, economy and people – particularly the world’s poor – and it is time that global society recognises the full extent of the effects of Climate Change.

These effects are not just the direct and immediate costs of climate change – those easily viewable and provable – but also making the link between the complex and gradual impacts which are just as catastrophic to humanity. In this sense, the loss 370,000 lives to climate change are just the tip of the iceberg: we need to reach deeper into the complexities of our analyses of the human cost of climate change in order to affect action to protect the poorest members of the planet.
