From the article: For all the progress our society has made, we’re still nothing without agriculture. But agriculture has also changed a lot: increasingly, an array of sensors equipped with relatively simple hardware and smart software are being used to make agriculture more efficient and sustainable — and given that agriculture is one of the main contributors to habitat destruction and climate change, this would definitely come in handy.
But unexpected help may come from the internet. The internet you’re using to read this now can be used for a number of different things, including connecting sensors and other objects.
The so-called Internet of Things (IoT) means that you no longer need to go out into a field to inspect it and take samples for analysis — you can leave the sensors in place and they communicate using wireless protocols. These technologies have advanced tremendously in recent years, becoming not only more precise and robust, but also cheaper — a key demand for agriculture.
It works like this: you plant a bunch of sensors to measure things like soil moisture, fertilizer content, and other parameters of interest. You connect the irrigation systems to the sensors and only irrigate when it’s necessary, and where it’s necessary. You can use the same approach for estimating soil nutrient levels and identifying pests, making the entire process as efficient as possible.
The results are, with today’s technology, striking: studies show that between 20% to 72% of water usage can be reduced with this approach, saving money and valuable environmental resources. There’s no doubt that the method has a lot of potential and can be used in most places in the world — although it’s noteworthy that some of the bread baskets of the world still lack access to reliable, high-speed internet.
