In a new study scientists have found that smallholder farmers in Ethiopia grow more of the indigenous crop Ensete ventricosum in the direct aftermath of severe droughts as a means of bolstering food security.
Scientists in Colombia show that well managed pasture can store more soil carbon while reducing nitrous oxide (N2O) emissions to offset the climate impact of livestock.
Researchers have identified a new reason to protect mangrove forests: they’ve been quietly keeping carbon out of Earth’s atmosphere for the past 5,000 years.
The maximum summer temperature and the amount of rainfall in summer are the two climate factors that determine the type of native grass that grows in a region, Australian researchers have found in a recent study.
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.
