Agriculture

Every year, global food systems produce, process, transport, and market the food and agricultural products on which the world relies. However, these same global food systems also play a big role in—and face pressures from—climate impacts, environmental damage, food insecurity and malnutrition, public health problems, and food loss and waste. To tackle these challenges, we must urgently transform food systems. True food system transformation will have to go beyond the agricultural policy reforms enacted during the past 50 years.

New technologies like remote sensing, digital advisory services, and digital financial tools have the potential to dramatically transform agricultural value chains in low- and middle-income countries (LMICs). But are these countries able to truly take advantage of this potential? Not without further investment, says a chapter in the recent book titled Science and Innovations for Food System Transformation.

With global population expected to reach 10 billion by 2050, the world’s ability to nourish its inhabitants is under threat if current trends continue.

As the world grapples with the increasing impacts of climate change, global policymakers need to take much stronger action to reduce the emission of greenhouse gases (GHG). This is the message from the recent UN Environment Programme’s Emissions Gap Report 2022. The report provides the stark conclusion that current national climate change pledges can only limit global warming rises by 2.4-2.6°C by the end of the century – far from the 1.5°C goal set forth by the Paris Agreement. To stand a chance of reaching that ambitious goal, global GHG emissions need to be cut by 45 percent by 2030.

Mitigating climate change and the degradation of natural resources while increasing the production of safe and nutritious food to eradicate hunger and ensure food security for a rapidly growing population is the most important and urgent challenge facing humanity today.
