KAUST Leads Global Initiative To Combat Land Degradation And Enhance Food Security By 2050

Research led by King Abdullah University of Science and Technology (KAUST), in partnership with scientists from five continents, provides a strategy to counteract the rapid land degradation threatening food and water security, social stability, and biodiversity. The study, published in Nature, suggests three actions to reverse this trend by 2050: boosting sea-based food production and consumption, cutting food waste by 75%, and restoring half of the degraded land.

The study emphasises that sustainable seafood farming is already feasible. It can significantly boost food production while supporting land restoration efforts. By promoting favourable aquaculture policies and development, land stress and deforestation can be reduced. These policies could save 17.1 million square kilometres of land. Combined with land saved from reducing food waste, this equals an area roughly the size of Africa.

Currently, one-third of food produced globally is wasted annually, valued at over $1 trillion. The study's new analysis reveals that food production uses 34% of ice-free land today. If current trends persist, this will rise to 42% by 2050. The scientists suggest simple measures like adjusting economic incentives, encouraging food donations, and promoting smaller restaurant portion sizes to save an estimated 13.4 million square kilometres of land.

More than 90% of farms worldwide are small or family-owned, with many already practising sustainable land management. The study argues for policies that help these small-scale farms increase their production and access sustainable agricultural technologies. This approach will aid in restoring land while preserving farm families' livelihoods.

"By transforming food systems, restoring degraded land, harnessing the potential of sustainable seafood, and fostering cooperation across nations and sectors, we can ‘bend the curve’ and reverse land degradation," said KAUST Professor Fernando Maestre, a global expert on land degradation and lead author of the study.

Reducing Food Waste

The research highlights that reducing food waste is crucial for reversing land degradation. Implementing strategies to cut waste by 75% is one of the key actions proposed. This reduction would not only conserve resources but also contribute significantly to saving vast areas of land from further degradation.

The scientists involved assert that all these approaches are practical and achievable. By focusing on transforming food systems and enhancing cooperation across various sectors and nations, significant progress can be made towards reversing the current trajectory of land degradation.

This comprehensive plan offers a viable path forward to address pressing global challenges related to environmental sustainability while ensuring continued agricultural productivity.
