Nourishing the world of the future | Nature Climate change

Agriculture and food are large economic sectors that support the livelihoods of many people. However, when thinking about food and climate change, the focus is often on the environmental impact of dietary choices. But for many, this is an unthinkable luxury, as food security, or ensuring access to sufficient, affordable and nutritious food, is a major concern.Climate change worsens food security¹which not only impacts production, but also potentially reduces income for producers as a result of addressing the challenges posed by climate change.

As food is transported around the world, we tend to become accustomed to having a full range of produce available throughout the seasons, cutting us off from natural cycles and making us vulnerable to weather and climate change. Data are available on the effects of climate change on many crops, including major crops such as corn, rice, soybeans, and wheat.², around the world, including predictions in various scenarios. However, putting this knowledge into practice to ensure food security for all will require significant efforts.

The ways in which climate change can affect food production include more obvious ones such as temperature extremes (both hot and cold), water availability (too much, too little), and seasonal changes. to potentially less obvious ones such as climate change. The decline of pollinators and their critical role, ocean heatwaves and changes in circulation are altering fish and shellfish stocks.

Most of the world’s farms are small farms, many of which come from the poorest communities.³. These farms have high yields for their small plots of land and often produce a significant portion of the world’s food, but they are labor-intensive, have low profits, and the costs associated with climate change are threatening their survival. It is reducing the ability. A recent study found that all survey respondents, small-scale forestry and agricultural producers with up to 10 hectares of land, were affected by water availability and timing, or whether it was related to increases in pests and diseases. It turns out that we are experiencing some effects from climate change.^Four. As a result, his 20-40% of a person’s annual income will be spent on production and adaptation and maintenance of livelihood. Although the terminology and definitions used when considering food producers may vary, we focus on the important role they play in feeding the world and support the growth of sustainable agriculture. We definitely need to support it.

A United Nations report focusing on the challenges of climate change, poverty and hunger in the Asia-Pacific region finds that as the risks of climate change, such as heat, drought and floods, increase, crops and agricultural production will be directly affected. It turns out that not only are there losses, but there are also losses.Improving labor productivity is essential for the survival of small farms^Five. When extreme events displace people, even for short periods of time, there is no one left to work the land and the loss of income increases vulnerability.

Research is needed on adaptation and innovation to changing temperatures and water availability. We need to develop a better understanding of the factors that can influence yield, such as soil quality.⁶as well as assisting in optimizing agricultural practices, developing crop varieties, and implementing technology where appropriate.⁷. However, identifying and developing climate-resilient crop varieties is not enough, they also need to be accepted and adopted by farmers, which can be difficult due to crop variety availability and information.⁸.
