By the end of last July, the InfoAg conference took place in St Louis, Missouri. Matt Waits, CEO of SST Software, a conference sponsor, introduced me before my presentation titled “Beyond the Farm of the Future”. In his brief introduction he told the audience that he strongly believes that precision agriculture is the future of agriculture. His statement resonated quite positively with me. I see only advantages in making agriculture more precise. Just for starters, per definition the opposite of precision agriculture would be an imprecise agriculture. That is already reason enough to become a supporter of precision agriculture.
The first reason why a precise agriculture is the way to go is the necessity to manage finite resources more efficiently. Precision agriculture means sustainability. The philosophy behind precision agriculture is to use only what is needed where it is needed when it is needed in the mount that is needed by crops. In practical terms, this means that every molecule of input in agricultural production has to be transformed into food and not end up in the environment. Precision agriculture reduces waste. When I was writing my first book on the future of agriculture in 2009, the estimated worldwide amount of nitrogen loss due to leaching was of about 50%. The example of nitrogen shows what reducing waste can mean. In an ideal world where nitrogen would be used much more efficiently, it could be possible theoretically to use only half of the nitrogen we have been using, or in other terms, the current amount of nitrogen used should help produce twice as much food. Considering that the FAO claims that between 2010 and 2050, agricultural output should increase by 70%, it means that in an ideally precise agriculture, the world could meet the demand for agricultural products by using 15% less nitrogen than it did in 2010, theoretically. Also considering that the production of chemical nitrogen fertilizers represents about half the use of fossil fuels in agriculture, the positive impact on the carbon footprint of agriculture would be substantial. Similar calculations can be done on other inputs, such as water and crop protection products. By bringing just the right quantities at the right time at the right place, the consumption of water and chemicals will be reduced substantially, too. As recent droughts have reminded us how precious water is, precision watering is also becoming more important than ever. Water is precious, but in many cases, its price has not emphasized this enough. The main reason for wasting is always the result of economics. If inputs appear cheap, the low price is always implicitly perceived as a sign of abundance and of negligible value. Such a perception goes against the reflex of sustainability. Our elders did not waste anything (candle bits, soap bits, socks, you name it). They were frugal simply because the cost of replacement was too high, and at least was higher than the cost of repairing and saving. When a government subsidies inputs to make them cheaper, the users end up wasting much more. It is sad because such subsidies always have a well-meant starting point. The idea is to make it affordable to poor farmers so that they can increase their production. The result is when the less poor ones get the subsidies, they do not see the new price as affordable anymore but they see it as cheap instead. Managing for sustainability really is about managing the fine line between affordable and cheap. That is not easy, because the difference is not just about the price of inputs; it is also about the financial situation of the subsidy’s recipient. Subsidies should not be aimed at just price, but at more at efficient use of inputs and should be based on achievable yields. If governments wish to spend money, it should not result in farmers overusing and wasting water and production inputs. That is counterproductive. These governments, which often are in developing countries where resources are scarce and access to inputs difficult, had better spend money on helping farmers being more precise. The math is simple: efficiency is the ratio output/input, and the difference between what comes out and what got in the field in the first place is what is wasted – or lost. A precise agriculture reduces the waste, and therefore increases the ratio. This means that precision is the way toward increased efficiency.
As I mention developing countries, here is another important point to bring up: precision agriculture is not just for large farms but can be implemented everywhere. The development of precision agriculture goes parallel with the development of new technologies. At first, it would seem that such technologies are too expensive for small and/or poor farmers. If the point of view were to be that every farmer should own all the precision equipment, the answer is: yes, it is only for the large and wealthy, but looking at precision agriculture from that angle would be rather dull. Satellite imagery, drones, sensors, robots and other big data software can also be shared. In the era of the cloud and social media which are all about sharing, so can new technologies. Just like ownership of agricultural machine has also been shared through equipment coops for instance, so can these new devices. After all, it does not matter so much who owns them, as long as those who need it to do a good job can have access to them. Mobile communications have changed how farmers everywhere can get the latest information on markets. Smart phones have become affordable to the point that there are about as many mobile phones as people on the planet. Similarly to mobile communications, precision agriculture will also become more affordable in the future. If precision agriculture tools can monitor, map and help make fast decisions on farms of tens – and even hundreds – of thousand acres, they just as well can look after an area of the same size even if it is divided between many farms. It is just a matter of management and coordination between farmers. In poorer regions, it could very well be that the authorities be the owner of the equipment and proactively communicate with farmers through extension services to help the groups of farms manage the region efficiently for higher output. Such tools will help developing agriculture, in a sustainable manner. The benefits will be many. It will help increase farmers revenues, create economic activity, enhance social stability and help reduce the waste of water, energy and all other inputs. It will pay off in the long run and actually probably in the not-so-long run at all. Agricultural development requires financing and investments. Precision agriculture is in my opinion a very good place to put money at work.
In the future, the key for these technologies will be to also help see the bigger picture, not just the field and not just production data. The potential for applications and interfaces seems almost endless. By connecting all the devices and allowing sharing information of all events taking place on farms, these technologies are going to help reconcile the interests of all stakeholders much more effectively than it has been the case in the past. By monitoring production parameters as well as environmental parameters, proactive action will help anticipate instead of reacting. Actions will be targeted timely. One of the difficulties to manage sustainability is one of timelines. It is possible to monitor financial performance on a second to second basis, even faster actually, in the case of financial markets where algorithms can execute millions of transactions in less than a second. Environmental impact does not manifest immediately. It takes decades to notice the impact of a particular type of activity. With this time discrepancy between financial performance and environmental performance, it is only logical that money has trumped environment, even though there is a price to pay some day. That is the dilemma of externalities: how to factor such externalities when the exact cost is unknown. The future generations of technologies to monitor and map agriculture and environment will bring solutions. Once the focus widens from the field to the level of regions, countries and the entire planet, then it is possible to envision monitoring systems for all resources, environmental impact of agriculture and production output. It is only logical to expect dynamic information systems that could look like Google Earth, but with many editions, such as, the aquifer status edition, the nutrient edition, the crop yield edition, the soil erosion/restoration edition, the pest edition, the contaminants edition, and so on and so on. With such dynamic systems, it will be possible to not only monitor but to also produce simulations and test different scenarios. It would become possible to have an idea of how long resources can last, depending on different production techniques. It could be possible to make estimates and develop policies to adapt agriculture timely and ensure that future practices will maintain sustainable production systems. With such tools, precision agriculture, it will possible to develop worldwide policies and strategies to coordinate agricultural production. It also will help make markets much more transparent, as such dynamic systems would take into account consumption demand, worldwide stocks and production updates. Such transparency will reduce risks of speculation as the system would present a continuous update on the most likely scenario. Let’s face it! The computers will eventually replace the market places or agricultural commodities.
I agree with Matt Waits, precision agriculture will be the agriculture of the future. I also believe that the technologies that agriculture will use will play a role at a much larger scale and beyond just agriculture to shape the way we deal with our planet and our societies. Precision agriculture will play a crucial role in ensuring food security and prosperity.
