台灣土地永續發展目標評估之跨領域模式建立(III)

Land is a vital resource. Improper or excessive use as well as droughts or erosion have caused land degradation. Due to increasing global population, damaging extreme weather events, westernizing dietary habit, non-decreasing food loss and waste, food shortage is very likely to occur in the near future. However, changing natural land into agricultural use may not only intensify land degradation, but also increase greenhouse gas emissions. Since efforts on interdisciplinary research have been made to address proper land use under the goal of achieving global net zero emissions, zero hunger, and maintaining biodiversity, it is necessary that Taiwan also build the capacity to contribute to the global sustainable development goals. The purpose of this study is to establish a systematic approach to support decisions of sustainable land resource utilization and agriculture and livestock production. The schedule of the project is three year. In the first year (2020) , the purpose is an interdisciplinary model LandNET (Land and Nutrient, Emission, Trade) is developed. The achievement progresshas completed the model establishment, and the historical data is used for model verification. In the process of establishing the model, the process of data gap analysis and stakeholder participation will also be completed. The goal of the second year’s (2021) research is to understand the current social and economic conditions in Taiwan, quantify its indicators, and co-produce the model with stakeholders. The input data of the model has been verified in the first year. In the second year, the internal calculation value of the model is mainly verified. Atpresent, 70% of the verification of the top three import and export agricultural and animal products has been completed. The third year (2022), through the integration of natural sciences and social sciences, climate change mitigation and adjustment, and opinions from researcher and stakeholders, the co-designed, coproduced, co-delivered model provide comprehensive implications to sustainable development of land and agriculture. In addition, the results of the study also contribute to the sustainable development goals of Taiwan on greenhouse gas reduction, national land plans, sustainable land use, food security and sustainable food production systems.
