Increased demand for water will be the No. 1 threat to food security in the next 20 years, followed closely by heat waves, droughts, income inequality and political instability, according to a new study which calls for increased collaboration to build a more resilient global food supply.
The effects of drought on major crops that are crucial to achieve both food and energy security. A global, more robust vision of this complex issue to advance the existing knowledge and support better informed, science-based decisions in the future, like fine-tuning crop calendars or implementing other measures as alternative cultivars, additional irrigation, and crop migration.
Science reporting on climate change does lead Americans to adopt more accurate beliefs and support government action on the issue – but these gains are fragile, a new study suggests.
The absence of large herbivores after the extinction of the dinosaurs changed the evolution of plants. The 25 million years of large herbivore absence slowed down the evolution of new plant species. Defensive features such as spines regressed and fruit sizes increased.
Airborne pollen may induce annoying congestion for some, but a new paper shows that these grains may provide a new way of looking at the climate over 300 million years into the fossil record.
Many countries have set carbon neutrality as a policy goal, but according to a new study by an international team of researchers from Austria, Japan, and the US, there are various risks associated with the reduction of greenhouse gases, especially in the agriculture, forestry, and land use sectors, that need to be considered when formulating mitigation strategies.
Local and Indigenous communities warn of a significant decrease in the abundance of wild edible plants and mushrooms that negatively impacts their nutrition and food security, from local to global scales.
Seven to nine percent of all vascular plant species occurring in Europe are globally threatened. The researchers combined Red Lists of endangered plant species in Europe with data on their global distribution. It helps assess the overall level of threat to plant species and thus supports the basis of international nature conservation activities.
A new study provides key insights into how and why tree populations migrate in response to climate change at the continental scale.
Feeling the heat: Steroid hormones contribute to the heat stress resistance of plants. Plants, like other organisms, can be severely affected by heat stress. To increase their chances of survival, they activate the heat shock response, a molecular pathway also employed by human and animal cells for stress protection. Researchers have now discovered that plant steroid hormones can promote this response in plants.
