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.
Violets reproduce both sexually, through cross-pollination of the showy flowers we’re familiar with; and asexually, by self-seeding of less noticeable flowers that remain hidden near the base of the plant. This is called “mixed mating.” Although environmental factors drive how much a plant reproduces sexually or asexually, no study had previously looked at the impact of climate change on mixed mating.
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 researchers have evaluated the impact of the effects of climate change on vital parameters of bean varieties, such as their morphology, reproduction, production, and phenology. Thus, they have detected some very sensitive types to variations in their conditions of origin. These others perform better with the increase in temperature, and others are highly resilient to any change.
Low-cost “tree fitbits” can pinpoint the precise timing of tree activities, like spring bloom or autumn leaf change, according to a new study. Researchers outfitted two ash trees with high-resolution accelerometers, efficiently tracking how the trees responded to changing seasons.
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.
First-of-its-kind analysis suggests declines in land suitability in most major producing countries. A new analysis predicts that, as climate change progresses, the most suitable regions for growing coffee arabica, cashews, and avocados will decline in some of the main countries that produce these crops.
