Closing yield gaps: how sustainable can we be
WebMay 25, 2024 · In fact, less than one-third of the global population would be capable of meeting its food demand from local crop production (even if food waste is reduced, yield gaps are closed, and diets are adjusted to more efficient crop mixes), and only 11–28% could fulfil their demand for specific crops within a 100-km radius. WebBy closing yield gaps in the current irrigated and rain-fed cultivated land, about 24% and 80% more crop calories can respectively be produced compared to 2000. Most countries will reach food self-sufficiency or improve their current food self-sufficiency levels if potential crop production levels are achieved.

WebYield gap definitions by necessity actually focus on yield potential which Lobell et al.(2009) argued can lead to inconsistencies in analyses and thus a plethora of yield gap ranges. Gomez (1977) divided the yield gap into two types, the gap between experiment station and farmers’ fields and the gap between
WebThe significant benefit of closing the yield gap for maize, rice and wheat is illustrated by the amount of future land area at stake that could be gained by closing yield gaps.
