Roughly 5% of global natural gas demand is for the synthesis of nitrogen fertilizers.Many agricultural production areas have good access to solar and wind resources. Most energy used in the food system comes from fossil fuels, although renewable energy’s share is rising.Roughly 30% of global energy consumption comes from the food system. Every part of the food system uses energy. The food system and energy system are deeply intertwined. Deforestation is occurring most rapidly in Latin America, followed by Africa. The vast majority of tropical deforestation (75%–90%) stems from expanding agricultural land for the production of commodities such as beef, soy and palm oil.Overgrazing is the number one cause of land degradation and desertification globally, causing about 35% of human induced soil degradation.Of the total land area used for agriculture, roughly two-thirds are pastures and rangelands for livestock grazing and production.Roughly 35% of the world’s total land area excluding Antarctica is used for agriculture. In 2019, the export value of all food products traded internationally was over $1.8 trillion.In high-income countries, agriculture contributes 1% of GDP on average.In middle-income countries, agriculture contributes 8% of GDP on average.In low-income countries, agriculture contributes 22% of GDP on average.In general, agriculture’s share of the economy declines as countries grow wealthier.The food system supports the livelihoods of over 1 billion people.
It includes food production, transport, processing, packaging, storage, consumption and disposal.įigure 1: A simplified diagram of food system activities Ī 2019 World Bank study estimated that the food system contributes $8 trillion per year to gross domestic product (GDP)-roughly 10% of the global economy. The food system spans a vast array of activities-from land clearing to fertilizer manufacturing to crop growing to livestock production to fish harvesting to meal preparation to landfill management. The final section (Part 5) presents strategies for reducing emissions from the food system and improving the resilience of the food system to climate change. This InfoGuide provides background on the food system (Part 1), climate change (Part 2), the impact of the food system on climate change (Part 3) and the impact of climate change on the food system (Part 4). Food choices play a central role in human health and culture. More than a billion people, mostly women, prepare food as a central part of everyday activities. Hundreds of millions of people work in agriculture and other aspects of food production, with the highest percentages in developing countries. Climate change creates significant risks to the food system, with rising temperatures and changing weather patterns threatening enormous damage to crops, supply chains and livelihoods in the decades ahead. If those emissions continue to increase at their current pace, meeting the Paris Agreement’s 1.5☌ (2.7☏) goal would be impossible even if non-food system emissions fell to zero immediately. Garber, struck a conciliatory tone, mentioning climate change and not coal, and drew polite applause.The food system contributes more than 30% of the heat-trapping gases emitted by human activities globally each year. On Thursday, the top American diplomat at the talks, Judith G.“What is to be gained?” a United Nations official asked. Yet delegates from other countries have refrained from openly criticizing the United States.The Trump administration has sent a delegation to Bonn, but the American negotiators are hashing out the details of a climate deal that President Trump has vowed to abandon - “ like a spouse who demands a divorce but then continues to live at home,” as our reporter put it.The United States is in an awkward position It was a stark reminder that the real action on global warming often does not unfold in international venues. The talks ultimately kicked most of the big issues down the road until 2018.Some island nations, extremely vulnerable and frustrated by the slowness of the United Nations process, have started to look elsewhere for aid.Led by Canada and Britain, 19 countries will end their coal power use by 2030.
