(CSIS) Seeding Security: Why Agrobiodiversity Loss Threatens National Security

Q1: What is the status of global agrobiodiversity?

A1: Today, biodiversity is being lost faster than at any time on record. Since the turn of the twentieth century, the average abundance of terrestrial native species has declined by at least 20 percent across most ecosystems around the world, while the number of crop varieties grown on farms has fallen by more than 90 percent over the last 100 years. Paradoxically, it is the agrifood system itself that is the primary driver of the ecological disruption and degradation imperiling agrobiodiversity around the world.

The environmental impacts of modern food production are myriad. About half of all habitable land on Earth is used for agriculture, while agricultural practices and other human activities have degraded up to 40 percent of the world’s land. Some industrial agriculture has led to the overexploitation of resources that drives habitat loss, the decline in the number of crop species and erosion of crop genetic diversity, and the introduction of invasive species and pollutants—all of which disrupt fragile ecosystems.

In this context, agriculture faces the opposing challenges of increasing food production to meet the needs of a growing global population, while reducing its ecological footprint to ensure that natural resources required for productive agriculture are sustained. In the absence of policies that safeguard agrobiodiversity, efforts to meet food demands threaten to erode the foundation of food production itself.

Read it all.

Agriculture is increasingly strained by growing food demand, global conflict, and the loss of its most foundational resource, agrobiodiversity. This loss threatens not just food security, but global security writ large.
