Rice, a staple for billions, is one of the most resource-hungry crops on the planet—but scientists may have found a way to change that. By applying nanoscale selenium directly to rice plants, researchers dramatically improved nitrogen efficiency, boosted yields, and made grains more nutritious while reducing fertilizer use and cutting greenhouse gas emissions.
Read moreA team at RMIT University has created a cement-free construction material using only cardboard, soil, and water. Strong enough for low-rise buildings, it reduces emissions, costs, and waste compared to concrete. The lightweight, on-site process makes it ideal for remote areas, while its thermal properties naturally cool buildings. Researchers see it as a key step toward greener, more resilient architecture.
Read moreLand is critical to human livelihoods and wellbeing, while actions related to land use also play an important role in the climate system. Researchers have developed a new roadmap outlining actions on deforestation, restoration, and carbon cuts that could lead to the land sector becoming carbon neutral by 2040 and a net carbon sink by 2050.
Read moreThere are many shortfalls in knowledge of the world's biodiversity, and one of the most basic is the lack of knowledge about where species occur geographically. This deficiency has broad ramifications for research and conservation. This study suggests the development of citizen science programs to collect data by volunteers has the potential to reduce this shortfall.
Read moreThe ways climate scientists explain their predictions about the impact of global warming can either promote or limit their persuasiveness.
Read moreScientists have estimated the emissions intensity of carbon dioxide and other air pollutants from a major electricity distributor and highlighted key consequences – essential information for policymakers shaping decisions to reduce electricity system emissions.
Read moreClimate change concerns have largely ignored the importance of universal access to effective contraception, despite the impact of population growth on greenhouse gas emissions, argue experts.
Read moreGiven the alarming pace of climate change, it is increasingly important to understand what factors motivate people to take action – or not – on environmental issues. A recent study shows that deeply held values, which align closely with political leanings, can predict whether someone takes action to protect the environment.
Read moremuch attention has been given to the growth of the 'Blue Economy' — a term which refers to the sustainable use of ocean and marine resources for economic growth, jobs, and improved livelihoods. Ocean resources are viewed as lucrative areas for increased investment, including in fisheries, aquaculture, bio-prospecting, renewable energy, oil and gas, and other businesses. Ensuring that socially equitable and sustainable development occurs should be the mandate of governments and industry, maintain an international group of researchers, led by UBC.
Read moreHydrologic models that simulate and predict water flow are used to estimate how natural systems respond to different scenarios such as changes in climate, land use, and soil management. The output from these models can inform policy and regulatory decisions regarding water and land management practices. Numerical models have become increasingly easy to employ with advances in computer technology and software with graphical user interface (GUI). While these technologies make the models more accessible, problems can arise if they are used by inexperienced modelers.
