A three-course action plan that will result in a much healthier planet.

The way we use land has a profound impact on our planet’s health. According to the UN’s Intergovernmental Panel on Climate Change (IPCC), agriculture, forestry, and other land use activities accounted for around 13% of CO2, 44% of methane, and 82% of nitrous oxide emissions from human activities globally during 2007-2016.

As the climate crisis intensifies, it’s clear that we need to rethink our relationship with the land. Protecting natural areas, reforestation, and adopting sustainable agricultural practices, combined with a shift towards plant-based diets, can be a powerful strategy in the fight against climate change.

The current state of land use paints a concerning picture. The World Resources Institute reports that the world has lost one-third of its forests since the last ice age, with an area the size of the United Kingdom disappearing each year. Meanwhile, unsustainable agricultural practices like intensive tillage and overgrazing are degrading soil health, reducing biodiversity, and contributing to greenhouse gas emissions.

Healthy ecosystems are vital for sequestering carbon from the atmosphere. When forests are cleared or wetlands drained, carbon storage capacity is lost, and the carbon stored in the soil and vegetation is released, further exacerbating climate change.

To address this challenge, we need a three-pronged approach:

First, protecting natural areas like forests, grasslands, and wetlands is crucial. The UN’s REDD+ program, which incentivizes developing countries to keep forests standing, has shown promising results. Since 2008, it has helped protect over 6 million hectares of threatened forests.

Secondly, we must actively restore degraded lands through reforestation efforts. Initiatives like the Bonn Challenge, a global goal to bring 150 million hectares of degraded and deforested landscapes into restoration by 2020 and 350 million hectares by 2030, can make a significant difference.

Thirdly, transitioning to sustainable agricultural practices is key. Techniques like agroforestry, where trees are integrated into farming systems, can sequester carbon, improving soil health and yields. Project Drawdown estimates that silvopasture, the integration of trees and grazing livestock, could sequester over 31 gigatons of CO2 by 2050 if adopted on just 25% of global grazing land.

In parallel to these land-use strategies, a shift towards plant-based diets can lessen the pressure on land. Animal agriculture currently uses 77% of global farming land while providing only 17% of humanity’s food supply. As the demand for meat and dairy grows with rising global affluence, so does the need for land for grazing and feed production, often at the expense of forests and other crucial ecosystems.

The good news is that plant-based diets are on the rise. A 2021 Bloomberg Intelligence report projects that the plant-based foods market could grow to $162 billion by 2030, up from $29.4 billion in 2020. If this trend continues and is supported by policy changes, it could significantly reduce the land use and greenhouse gas impacts on our food system.

However, it’s important to acknowledge that a complete global shift to veganism is unlikely. Where animal agriculture continues, it’s crucial to support farmers in adopting sustainable, humane practices like rotational grazing and integrating crop and livestock systems.

The real power lies in combining these approaches. Imagine a future where our plates are filled with diverse, nourishing plant-based foods grown using regenerative practices. The land freed from industrial animal agriculture has been rewilded, reforested, and restored to vibrant ecosystems teeming with biodiversity.

Where sustainable, small-scale livestock farming works in harmony with the environment. This synergistic effect could draw down significant carbon from the atmosphere while providing co-benefits like cleaner air and water, improved public health, and enhanced resilience to climate impacts.

But this vision won’t manifest without action. As individuals, we can make a difference with our food choices, opting for more plant-based meals and supporting local, sustainable farms. We must push for policies that incentivize regenerative land use practices and make healthy, sustainable food accessible to all. We must hold businesses and leaders accountable and demand investment in research and infrastructure to support this transition.

The challenge is immense, but so is the opportunity. We can create a more sustainable, resilient, and just food system by rethinking how we use land and what we put on our plates. We can nourish both people and planet. The choice is on our plate, and the time to act is now.
