Hemp is a non-psychoactive (less than 1% tetrahydrocannabinol) variety of Cannabis sativa L. It is cultivated on hills and used mainly for textiles. Hemp requires less water and pesticides. It grows fast (4-5 meters in 3-4 months) and has a high carbon sequestration rate of 1.36 kgCO 2 e per kg of hemp fiber. This study aims at exploring the potential use of hemp for construction materials. By applying the upcycling design concept, hemp stalks left after fibre harvesting were sun dried before grinding into small pieces of varying sizes. In addition, artificial stones (polyester-resin solid surface material) left over from production processes was also collected. Hemp materials and artificial stone scraps were used at different proportions to develop a new composite called Hempstone. The study found that Hempstone did not require the drying process; hemp fibers helped absorb the moisture. Hemp fibers also offered unique natural aesthetic. Quality tests were conducted to ensure that Hempstone was fit for use in construction. LCA (Life Cycle Assessment) was performed to identify the potential reduction of environmental impacts of typical artificial stone and Hempstone. The results indicated that the Hempstone sheet (0.823.040.012m) with 10% of hemp-stalks (5 mm size) and 7.5% or 10% by weight of artificial stone scraps performed best with the potential reduction of environmental impacts by 40% on climate change, 42% on freshwater eutrophication, 55% on terrestrial ecotoxicity and 60% on terrestrial ecotoxicity. Hence, the Hempstone sheet with 10% of hemp-stalk material and 10% of artificial stone scraps complies with the UPCYCLE Carbon Footprint certification and labelling requirement of minimum scrap content of 20% by weight. With the growing pursuit of green buildings, these reductions

There is no indicator measuring Thailand’s green growth by valuing the resource degradation and environmental damage costs. This article aims to estimate Thailand’s green gross domestic (GDP) that takes into account environmental damage costs with the detailed analysis on the agricultural sector using the Economic Input Output - Life Cycle Assessment (EIO-LCA) approach. The representative product in each sector was selected based on the available life cycle inventory data, economic values and their magnitude of impacts. Here we find that oil palm cultivation (Sector 011 in the economic input-output table), fibre crops (Sector 013), rice cultivation using chemicals (Sector 001), coffee-tea-cocao (Sector 015), and coconut growing (Sector 010), respectively, generated the highest environmental damage value. This study revealed that the total environmental damage costs of agricultural products was $22.05 million per year accounting for only 0.1003 percent of total GDP in agricultural sector while the total environmental damage cost from all sectors is equal to $36,950.79 million accounting for 14.58 of total GDP.

How can shifting diets-the type, combination, and quantity of foods people consume-contribute to a sustainable food future?Building on the United Nations Food and Agriculture Organization's (FAO) food demand projections, we estimate that the world needs to close a 70 percent "food gap" between the crop calories available in 2006 and expected calorie demand in 2050.

SUMMARY Fish—including finfish and shellfish—are an important item in the human food basket, contributing 17 percent of the global animal-based protein supply in 2010. They are an especially valuable food source in developing countries, where more than 75 percent of the world’s fish consumption occurs. In addition to protein, fish contain micronutrients and longchain omega-3 fatty acids that are essential for maternal and child health, but often deficient in the diets of the poor.

Fish—including finfish and shellfish—are an important item in the human food basket, contributing 17 percent of the global animal-based protein supply in 2010. They are an especially valuable food source in developing countries, where more than 75 percent of the world’s fish consumption occurs. In addition to protein, fish contain micronutrients and long- chain omega-3 fatty acids that are essential for maternal and child health, but often deficient in the diets of the poor.\nHowever, the global supply of wild-caught fish has long peaked and is unlikely to rise again unless overexploited stocks are rehabilitated. As world fish consumption continues to grow, aquaculture (fish farming) has emerged\nto meet demand. Already, just under half of all fish that people consume come from aquaculture, which is one of\nthe world’s fastest-growing animal food producing sectors. With the supply of wild-caught fish stagnant, any future increase in world fish consumption will need to be supplied by aquaculture.\nIn a resource-constrained world, aquaculture could be an attractive option for expanding animal protein supply.\nFarmed finfish are similar in feed conversion efficiency to poultry, and much more efficient than beef. Filter-feeding\ncarp and mollusks are even more efficient producers of animal protein, as they require no human-managed feeds\nand can improve water quality. Because the aquaculture sector is relatively young compared with terrestrial live-\nstock sectors, it offers great scope for technical innovation to further increase resource efficiency
