背景情况:
- 调和全球环境目标与日益增长的粮食需求对于AFOLU部门至关重要.
- 在AFOLU实现气候目标对于具有大量反动物牲畜和有限森林碳汇的国家来说是一个挑战.
- 爱尔兰的AFOLU部门面临着平衡气候目标与高牛蛋白生产的挑战.
研究的目的:
- 调查目前的爱尔兰牛蛋白生产水平与2050年净零温室气体 (GHG) 排放的兼容性.
- 使用综合评估模型探索未来的AFOLU场景.
- 评估温室气体减排措施和土地利用变化的影响,以实现净零.
主要方法:

RNA is the Missing Link Between DNA and Proteins
In the early 1900s, scientists discovered that DNA stores all the information needed for cellular functions and that proteins perform most of these functions. However, the mechanisms of converting genetic information into functional proteins remained unknown for many years. Initially, it was believed that a single gene is...
