The United Nations has set a Sustainable Development Goal to end world hunger by 2030. Increasing crop yields is necessary to achieve this goal. However, intensive irrigation practices can also increase the uptake of ozone by plants, damaging sensitive leaf tissues. Lack of ozone pollution mitigation efforts may prevent future progress towards global food security.
On a quest to find examples of food-secure islands, Sara Santiago interviewed Dr. Natalie Kurashima, who studies traditional agriculture practices in Hawaiʻi. With kindness, humility, and dedication, Natalie shares her experience of tying her research to her indigenous roots in Hawaiian land and agriculture.
The world’s growing population will place ever-greater demands on agricultural lands. A recent study suggests that a diversified approach to farming can promote conservation without sacrificing production.
Island peoples are at the frontlines of climate change. They are also often isolated and dependent on imports, especially for food. New research in Hawai’i investigates how indigenous agricultural systems may support food security, indigenous sovereignty, and climate change adaptation.
Climate change has started to impact agriculture, and therefore our ability to maintain food production for the future. Food security is a complex issue that should be tackled from various fronts. As a recent article points out, developing and widening the production of crops that can resist environmental stressors can be an essential part of the solution.
A shift towards plant-based diets could bring health and environmental benefits to the world. However, strong beliefs and psychological attachments to meat complicate this shift. Are we really willing to eat less meat?
Can recalling environmentally friendly behavior stimulate you to buy low-carbon emission supermarket products? Recent research analyzes strategies to decrease the carbon footprint of supermarket shopping, revealing that both remembering pro-environmental actions and carbon taxation policies stimulate sustainable consumption choices.
In the San Joaquin Valley of California, approximately 1 million people rely on groundwater for drinking. This high reliance on groundwater has resulted in overpumping of this resource, which leads to subsidence, or massive compression of the ground and arsenic contamination of the water. Arsenic is deadly to human health; therefore, it is imperative that California water agencies and individual water-users pump less groundwater and closely monitor arsenic levels.
Meat consumption in China is on the rise. This trend carries significant environmental implications. Despite environmental concerns, Chinese consumers continue to seek out meat. To keep the increase in meat demand from threatening global sustainability, the country will need to manage its livestock feed sourcing and manure in creative new ways.
