To adapt to climate change and ensure food security, major interventions are required to transform current patterns and practices of food production, distribution and consumption. The scientific community has an essential role to play in informing concurrent, strategic investments to establish climate-resilient agricultural production systems, minimize greenhouse gas emissions, make efficient use of resources, develop low-waste supply chains, ensure adequate nutrition, encourage healthy eating choices and develop a global knowledge system for sustainability. This paper outlines scientific contributions that will be essential to the seven policy recommendations for achieving food security in the context of climate change put forward by the Commission on Sustainable Agriculture and Climate Change. These include improved understanding of agriculture's vulnerability to climate change, food price dynamics, food waste and consumption patterns and monitoring technologies as well as multidisciplinary investigation of regionally appropriate responses to climate change and food security challenges.
This study reported the influence of oxidizer-fuel content and particle size of the fuel on combustion characteristics of the whistling mixture based on potassium perchlorate and sodium benzoate such as heat of explosion, the specific volume of gaseous products, burning rate and intensity of whistling sound. From the analysis of theoretical prediction and experimental data, we selected an appropriate ingredient and particle sizes of components in order to archive the optimal intensity of the whistle. The whistling pyrotechnic has a relatively low sensitivity to friction and could be safely used for several military and civilian applications.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
