In order to prevent this blog from simply become a glorified encyclopedia page about sustainable development, and of course to keep you (the reader) somewhat interested, I'm hoping this post will be the last 'strictly explanatory' posts about sustainable development. One can talk theory about anything for days, but without practice or real world examples and experience, theory is just that- theory. My goal is to develop these posts into more engaging, open platforms for readers to discuss and debate the issues I put forward, using examples of real world sustainable development practices.
But for now I will present to you the sustainable development Venn diagram (or trifecta). If you Google sustainable development, image results will give you a whole slew of charts and diagrams similar to the one below. Some more simple, others far more complicated. Personally, I find this to be the clearest interpretation of the sustainable development matrix because not only does it shows the intersection where sustainability is carefully achieved, but also the alternative development scenarios that are encounter if you were to neglect one of the other spheres.
As mentioned in the previous post highlighting the Brundtland Report, it is important to recognize that the environment does not exist as a sphere separate from human actions, ambitions, and needs. We cannot make changes or advancements in economics or society without having an impact on the natural world around us. The environment is where we live, and development is what we all do within this environment to progress our situation. There are actions, and there are reactions, and it is impossible for our human activity not to have an impact on the natural world.
Even more important, sustainable development does not advocate solely for the protection of the environment. It is of course a reaction to the recent trend of natural resource depletion, unregulated consumption, pollution, and climate change; but it ties together both the concerns for the carrying capacity of Earth's natural systems while recognizing the social challenges of humanity like poverty and hunger alleviation. The challenges that each sphere faces are not mutually exclusive and neither are the solutions. As the diagram shows, neglecting one sphere creates an incomplete development strategy which will eventually come to a developmental stand still or worse, collapse.
But in order for development to exist at all, there needs to be a fundamental focus on the consumption patterns of Earth's renewable sources. For a steady state economy to be achieved along with environmental equilibrium, our consumption needs to be equal to Earth's ability to replenish the source. Consuming more, as we are now, leads to unsustainable environmental degradation. Consuming less than the replenishable rate will create environmental renewal, although good for the planet, will slow the pace of human growth and development. As a result, we would no longer be able to meet many of the basic needs required of such a large and growing population, with such a high standard of living .
To put the current unsustainable consumption trend into perspective, the Global Footprint Network just announced August 20, 2013 as 'Earth Overshoot Day', or the approximate day in which our resource consumption for the year has surpassed the planet's natural ability to replenish itself. According to these
estimates, our demand for natural resources and CO2 sequestration are
equivalent to 1.5 Earths, a worrying estimate given our accelerating rate of
population growth and economic development.
Although other factors are often included in the sustainable development model like politics, culture, and ecology, these can often be considered sub-categories of the three main spheres; environmental, economic, and social. But to realize the strong link between these three areas is to realize a potential for powerful answers to many of our biggest global challenges. Our way of thinking about issues of environmental conservation, economic stability, class disparity cannot be looked at as isolated issues with unique and singular answers. We need a non linear approach which address the root of all these issues so that common solutions can be formed and steady, yet sustainable progress can be made.
