In order to sustain the world in the future, we need to increase agriculture efficiency. This means preserving water while ensuring it is high-quality, maintaining soil, and becoming smarter with fertilizer usage. We need to produce just as much if not more food while using less resources. This will lead to there being less land used and therefore less emissions let out into the environment from the agriculture process.
Studies predict that it is possible for farmers to produce more crops than they currently do today, but also show that yield gaps are far from being closed and the yield potential ranges anywhere from 24%-80%. This means that farmers are not currently closing any gaps, and it is unclear whether they will in the future since this depends on a variety of factors including how each individual agriculture system is managed. Not to mention, even a fully closed gap will not be enough to meet the demand for food.
