A picture of a skeleton accessorized with sunglasses and a plastic water bottle, surely, must go down as one of the most terrifying images of last year. Published in “The New York Times Magazine” with the headline “Uninhabitable Earth – Famine, Economic Collapse and the sun that Cooks Us ” gave a very detailed summary of an apocalyptic earth, where it’s not the grand meteor or an alien invasion that kills us, but simply lack of water as a result of climate change.
Whether you find this terrifying or, perhaps, think of it as exaggerated, one thing is certain: the world is getting hotter, a lot hotter, and Sicily is right at the centre of that climate change. Sixteen of the 17 warmest years since we started monitoring temperature all occurred since 2001 according to NASA and it is estimated that half of the world’s population will be living in a water deprived area by 2030.
It is fair to say that Sicily has already started feeling the consequences of this change. This week, we were told that the Palermo region is suffering a water crisis, which has not happened in Sicily for over 70 years and, consequently, the water might be rationed in extreme measurements. Last year, I could barely walk through my village without feeling out of breath, suffocated by the heat. The steamy haze from the sea settled like a blanket, making it impossible to see across the bay to Palermo by 11 am. By midday, we could safely say the village was uninhabitable and the empty streets with everyone passed out under the air conditioning could surely testify to that. When I looked at the statistics for the period, it turned out that the average temperature in August was somewhere between 35-40 degrees – unheard of for the Mediterranean climate.
As unpleasant and unbearable as the heat could be, the real problem arises when it comes to agriculture, and for an island with over 7000 small organic farms, this becomes a challenge for the people. Suddenly, small teams and families have to figure out a way to find enough supply to grow their crop, which is a lot more challenging than for larger corporations. Nevertheless, it is a challenge that has to be solved. Olive, grape and especially citrus all need significant amounts of water and without it, there’s nothing to export or to even put on the table. So, what could be the solution to this increasing problem?
It’s a tricky one, but surely, there’s no steam without water, so someone somewhere must be building something that makes it easier to live tomorrow. In fact, here are just three of the technologies that I picked which are the easiest and the most economic options amongst many solutions.
- A Mexican version of an aqueduct – an “Acequias” is currently being experimented with in some of the driest parts of the world. It’s great for terrain where mountains meet plains, just like they do in Sicily. It’s a simply made pipe that allows water to safely be transported from the mountains to the farm. Currently, such projects are maintained by groups of farmers, so extra facilities might be necessary to guarantee the cleanliness of the water. Luckily, water tests are available to anyone. I normally get mine online and pay just under €10 for a whole lot and with social media, there’s nothing to hide.
- A few years back, the Barbican in London launched an art project called “The Barbican Rain Room” – a rain system that people can walk through without getting wet. It was built on special sensors that track movement and could be programmed to people or objects. So, when the rain falls, or the tree is watered, it can be very specific to the exact areas of need saving up to 80% of the water wastage. As these sensors are flexible, they will develop as the tree grows and yes, you can make it stop raining in parts of your farm.
- Remote crop watering is something definitely on the cards over the next few years. Why go all the way to the farm if you can simply press a button at home? Simple technologies can be at the farmer’s service to make quite advance calculations – for example: how dry the soil is – what sort of insects are likely to occur in these conditions and notify when the crop needs watering, automatically switching off at exactly the right time. It can also act according to the future weather forecast. For example; if we’re expecting a rainy week, it will water the crop for just enough time to get it going.
These are just a few examples of what we can do with the very advanced tech we’ve got today and there’s surely much more to come. While none of these solutions can provide universal answers to all our problems, it is certain that there is a way to make things a little bit easier for ourselves and the planet – and where better to do it than the largest island in the Mediterranean?
