World's food supply 'under threat' from loss of biodiversity

The world’s food supplies are increasingly under threat from the ongoing destruction of the planet’s biodiversity, a new report has warned.

The world’s food supplies are increasingly under threat from the ongoing destruction of the planet’s biodiversity, a new report has warned.

Plants, animals and micro-organisms which are crucial to supporting and upholding the human diet are not being protected, the study by the United Nation's Food and Agriculture Organisation found.

It said global shortages would become increasingly likely if steps were not now taken to maintain such natural ecosystems.

“It is deeply concerning that, in so many production systems in so many countries, biodiversity for food and agriculture and the ecosystem services it provides are reported to be in decline,” wrote Graziano da Silva, director general of the organisation.

Some 20 per cent of the world’s vegetated surface had become less productive in the last 20 years, the study – which is based on data from 91 countries – suggested.

It said the decline of hundreds of species of insects, which help pollinate crops, were among the biggest worries. Birds that eat pests, and fish which maintain the ocean’s natural food chains were also found to be in dramatic decline.

“The foundations of our food systems are being undermined, often, at least in part, because of the impact of management practices and land-use changes associated with food and agriculture and the ecosystem services it provides are reported to be in decline,” said Mr da Silva.

Agriculture was often to blame, he said, as over-exploitation of land meant that plants, animals and micro-organisms which would historically help sustain food growth over the long-term were being destroyed.

Other causes include overexploitation of water supplies, pollution, over-harvesting and climate change.
