Although it may sound like a bit of semantics, the difference between these two terms is quite important when it comes to agriculture and food production.
Since WWII, much progress has been made to increase food production, such as genetic improvement, production techniques and mechanization, use of fertilizers, chemicals and pharmaceuticals, the development of animal nutrition, and of course government incentives. This has resulted in our ability to produce more efficiently and face a previous doubling of the world population. It has helped reduce costs and made food more affordable to more, although unfortunately not to all.
The main driver behind this evolution has been to shift from a mostly labor intensive food production to a mostly capital intensive one, and this why it had to become intensive. The labor force moved to urban centers where they could find jobs in manufacturing and later in services. Thanks to mechanization, less people were needed to work on farms. This has led to a sharp drop of the population active in agriculture from above 50% of all actives to less than 5% in Western countries within 30 years. Moreover, as the standard of living increased, labor costs increased and made a labor-intensive approach too expensive to fit in the type of society that we created, and the only, apparent, solution has been to further intensify and mechanize.
The strong development of manufacturing that went along with the rise of the consumption society increased the standard of living and the disposable income. In the same time, in constant currency, food became relatively cheaper and much more affordable. This led to a change of diet from mostly starch-based to protein-based, and we have seen recently a similar trend in emerging countries.
Clearly, all of this has improved the quality of life, maybe a little too much too fast though. Intensification has brought its share of problems as well, as it always does with progress. For instance, I can mention soil erosion and loss of organic matter, soil fertility and ground water quality affected by manure (especially minerals) surpluses, reduced genetic diversity and possibly lessened resistance to diseases, to name a few. Of course, for each of the problems, we come with a solution mostly based on technology, which usually fits in and reinforces intensification.
Unfortunately, Nature does not work that simply. All it needs is time to process and eliminate problems through its cycles in the soil and in the water. Nature can handle quite a lot, but it can handle only that much. This is where the difference between intensification and efficiency becomes obvious.
Intensification tends to continuously load and overload the system, which is why we hear so much talk about sustainable agriculture nowadays. Food production cannot be sustainable if it does not allow its natural environment to process and eliminate the contaminants. Similarly, Nature cannot replenish on its own what we take out, unless we create the conditions for this.
Efficiency, on the other hand, integrates performance and sustainability. It allows having a high production, not so much by using massive amounts of water, fertilizer, energy or other production inputs, but by using them when needed where need and just as much as needed. This way, we can grow plants or animals with the minimum amount of waste and respect the ecosystem. Efficiency also comes from optimization, and to this extent, efficiency and intensification go hand in hand, up to that particular point when any incremental input does not produce more in the same proportion. More importantly, once we produce beyond the optimum, we take the chance of creating a stress. This is very clear in animal production, when densities exceed a certain point, the animals’ organism defence becomes weak and makes them vulnerable to diseases.

In order to understand what changes are ahead of us, we need to realize that opposite forces are engaged in shaping the world of the future. As we all know, accepting change is always a slow and sometimes a difficult process. There are those who see the possibilities and those who see the drawbacks. The first train was going, supposedly, to get cows stop giving milk, but we now know that cows love to watch trains passing by. Probably, the first caveman who drew a picture of an animal on the wall was considered by some as a great magician and probably by others as pure evil. As such, such a struggle is very useful, as on the one hand it shakes immobility and open new doors, and on the other hand it prevents us to rush into the unknown without thinking first.
More technology to improve efficiency of water use, fertilizer use, animal feed use, land use, energy use (objective: zero waste).
Although some still try to resist and deny the obvious, this system is no longer sustainable and we must rethink what should drive our economy. In an earlier article, I made a reference of how previous generations used to be very cautious about what and how they consumed. The positive side of the last 60 years has been the incredible progress we have made in science, knowledge and technology, which offers possibilities unthinkable for the previous generations I was referring to. We understand our world and how it functions like never before. We have all the technological solutions to solve the climate issue, but the key is the will and the determination to change and to act. This cannot happen as long as we keep thinking the economy in terms of growth only. Growth will not go on for ever, simply because our space and our resources are limited. As there are more and more people needing more and more energy, food and other goods, the law of offer and demand will rule. Prices will inevitably go up and consumption will slow down. A new time has come. The priority must now be quality, not quantity, we must think about having enough, not having always more. This thinking is not a nostalgia to a past that also had its limitations. It is not about rejecting a market-based economy. It is about looking at the market that has always been here, but that has been pushed in the background for the easier approach of just producing more and selling it. What we will have to bring to market is not so much products as services. These services are the ones that are directly related to making all the natural and industrial cycles run harmoniously in a durable way. Just to name a few examples, I would mention all activities that are related to cleaning the damage we have caused, and recycling activities will become more and more important in our whole economy. In the same way, water treatment is going to be a crucial activity, even more so than it has been so far. Clean industries producing durable goods and services will prevail. This change will also make some jobs disappear and some appear or even reappear. As usual change always brings opportunities. It is to us to recognize them and to take them. The time has come to make the transition from this consumption society, based on wasting resources, and with no future, to a maintenance society, where wealth, and not growth, will be the economic success indicator. By acting today, we can ensure this process to happen in a smoother way than if we wait until we have no choice anymore.
With an increasing population that needs more food and more water to live, we can expect that water is going to become a highly strategic and needed resource. As climate changes, the current rain distribution and geographic availability of water is likely to change dramatically, too. This increasing competition between agricultural areas and urban areas will bring major changes on how we use water for both personal use and for food production. On the personal side, we certainly can expect that current bathroom systems to disappear, as they use too much water. Every time we flush a toilet tank, we actually waste the daily drinking water needs of a couple of people, and local water reserves are gradually depleted as well. Clearly, this has no future. Similarly, we can expect the legislation on water use for lawn sprinkling and car washing to change.
More efficient irrigation systems will replace the old ones. Computerized systems are already in use in wine production, using sensors for humidity and temperature, to determine how much water the plants needs at the most optimal time of the day and deliver it at the exact spot. You can expect that such an optimization approach will prevail. The path that Monsanto follows with the production of genetically modified (GM) wheat that needs only a third of regular wheat varieties is quite interesting. The tricky part is the GM part, as on the contrary to natural “mutations”, such a process does not undergo natural selection, and therefore we do not know what possible side effects it might bring. Nonetheless, this is an attempt to deal with future water shortages. Hopefully, other less controversial solutions can be found that will deliver a similar result. Once again, we can shape our future through continuing innovation.
