When I was in Indonesia, I learned that on the island of Bali alone, the suitability for rice paddy production has decreased 20% in the last 20 years due to changes in the climate.
With climate change comes increased droughts, increased floods, and increased temperature which reduces the harvest’s productivity drastically. In the long term, this leads to increased water vapor in the atmosphere and subsequent heavy downpours. These heavy downpours cause soil erosion which diminishes good soil needed for harvest. This, along with other factors, is impacting our food supply worldwide.
On average, since 1995, grain productivity has come down to about 1.2%, with the world’s population growth also at 1.2%. According to the UNDESA, the world’s population could increase to 9.7 billion people by 2050, compared to today’s 7.5 billion.
We have a growing population who want to eat meat, diminishing agricultural returns, and worldwide erosion taking 1% a year of the global soil and half a percent of our arable land. Then there is urban expansion taking the best arable land and concreting it over. Plus, there are water availability problems. Reservoirs in South Africa, Morocco, Spain, the US, are all shrinking, suffering from the increased heat. We’re depleting our aquifers: in heavily irrigated areas such as Las Vegas or the Central Valley of California, well water levels have fallen by hundreds of feet. In China, parts of Beijing are sinking by four inches a year.
Agriculture is affected by climate change, and it contributes to climate change. It is where climate change has its most consequential effects. Food sufficiency will prove to be one of our civilization’s greatest future challenge.
The Food and Agriculture Organization is promoting sustainable practices in various countries through agroecology. This is a series of social and environmental measures aimed at creating a sustainable agricultural system that optimises and stabilises crop yields. These practices also tackle the effects of climate change, such as desertification, the rise in sea levels, and practices that respect natural cycles while drastically reducing human impact.
