The FAO's comprehensive report The State of Biodiversity for Food and Agriculture highlights the critical role that diverse ecosystems play in sustaining agricultural productivity and resilience. Alongside this, the UK Government's report Balancing Nature and Agriculture emphasises the urgent need to reconcile these two priorities to ensure food security, as well as recognising that agriculture is dependent on biodiversity and that agricultural intensification is a major driver of biodiversity decline.
However, current arguments from some quarters seek to frame this issue as a polarised choice between food production and nature. This perspective suggests that efforts to protect biodiversity, restore ecosystems and make space for nature in our landscapes could undermine agricultural productivity.
The well documented loss of bees and other insect pollinators, which are vital for the pollination of most of our food crops, is just one factor. The loss of abundance of once common farmland birds that eat crop pests, the debilitating loss of soil and changes to soil biodiversity can all have a huge impact on food production. The decline of natural ecosystems and processes leads to a vicious circle of ever-increasing application of often chemical-based fertiliser and pesticides, which cause yet more damage to the natural environment. Inputs of fertilisers and pesticides will reach more than their intended target, and lead to the pollution of waterways with nitrates, phosphates, and chemicals toxic to aquatic life and ultimately our seas, damaging marine habitats and the species that depend on them, many of which are also important human food sources.
