The global climate system is changing and, until now, the drivers of these shifts have been hotly debated: is it caused by humans or is it normal climate variability? New research confirms that humans are the main cause of climate shifts – which will have important implications in support of swift climate action by managers and political figure.
While meat alternatives are gaining popularity, not all offer the same sustainability gains. In fact, the general perception of their environmental benefits may be skewed by the technological sophistication of their production. Awareness of these factors can positively influence the public to make more sustainable food choices.
Andrew Ofstehage, postdoctoral associate at Cornell University, used his background in agronomy and anthropology to investigate the soy boom in Brazil. In his upcoming book “Welcome to Soylandia!”, Ofstehage shows how transnational North American farmers are managing both soils and investors while creating narratives around their presence in Brazil.
Researchers are trying to unravel the mystery behind salmon size declines in Alaska and estimate their implications for humans and ecosystems. Quantifying these declines and understanding their impacts will be critical for future fishery management.
New research maps the global extent of glacial lakes and shows that climate change is causing an increase in the size of these lakes across the planet. As glacial lakes grow, the likelihood of glacial lake outburst floods (GLOFs) in high altitude areas is increasing. This study highlights the urgent need for adaptation planning in high risk mountainous communities that may be exposed to GLOFs as the planet warms.
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.
