Contributions of livestock-derived foods to nutrient supply under changing demand in low- and middle-income countries

For eight, selected low and middle income countries included in a cross-country study of the role of livestock, this dataset shows: (1) assumptions made about household incomes and total population in 2050, associated with four scenarios of global change; (2) scenario projections of household food demand and net trade in 2050; (3) nutrient composition of selected foods of plant and animal origins included in the study; (4) calories and nutrient supply per capita in the study countries in 2010; and (5) the percent contributions of different types of livestock-derived foods to countries' nutrient supply in 2010 and 2050.

本数据集针对一项探究畜牧业作用的跨国研究中纳入的8个中低收入国家，涵盖以下内容：
1. 与四类全球变化情景相关的2050年家庭收入与总人口假设；
2. 2050年家庭粮食需求与净贸易的情景预测结果；
3. 本研究选取的植物源及动物源食品的营养组成；
4. 2010年研究覆盖国家的人均热量与营养素供给量；
5. 2010年与2050年，各类畜源食品对研究国家营养素供给的百分比贡献。
