    • Malnutrition in all forms, ranging from undernourishment to obesity and associated diet-related diseases, is one of the leading causes of death worldwide, while food systems often have major environmental impacts. Rapid global population growth and increases in demands for food and changes in dietary habits create challenges to provide universal access to healthy food without creating negative environmental, economic, and social impacts. This article discusses opportunities for and challenges to sustainable food systems from a human health perspective by making the case for avoiding the transition to unhealthy less sustainable diets (using India as an exemplar), reducing food waste by changing consumer behaviour (with examples from Japan), and using innovations and new technologies to reduce the environmental impact of healthy food production. The article touches upon two of the challenges to achieving healthy sustainable diets for a global population, i.e., reduction on the yield and nutritional quality of crops (in particular vegetables and fruits) due to climate change; and trade-offs between food production and industrial crops. There is an urgent need to develop and implement policies and practices that provide universal access to healthy food choices for a growing world population, whilst reducing the environmental footprint of the global food system.

  • Life cycle assessment of a cement plant in Naypyitaw, Myanmar

    • Cement production accounts for about 5% of the total anthropogenic CO2 emissions and 12–15% of the global energy use from the industrial sector. The impact on climate change and natural resource depletion are among the key concerns of the cement industry. Cement demand has been growing rapidly in many developing countries due to a booming construction sector spurred by rapid urbanization. Myanmar is one of these countries and has started to privatize its cement industry to meet the growing domestic demand. This study aims to assess the environmental impacts of Ordinary Portland Cement (OPC) production in Myanmar using Life Cycle Assessment (LCA) for the Max Myanmar Cement Plant in Naypyitaw. The LCA examines the entire cement production chain, using two alternative scenarios for fuel substitution. The results suggest that conventional cement production has adverse environmental impacts, with the calcination stage being responsible for most impacts. Calcination accounts for 89%, 95% and 97% of the effect for the climate change, acidification, and eutrophication impact categories respectively. Fuel switching from the coal dominating mix to 100% natural gas can decrease environmental impacts for most mid-point impact categories, such as climate change (68% reduction), acidification potential (83% reduction), and eutrophication potential (96% reduction).
