This study investigates multi-dimensional impacts of adopting new technology in agriculture at the farm/village and watershed scale in sub-Saharan Africa using the Integrated Decision Support System (IDSS). Application of IDSS as an integrated modeling tool helps solve complex issues in agricultural systems by simultaneously assessing production, environmental, economic, and nutritional consequences of adopting agricultural technologies for sustainable increases in food production and use of scarce natural resources. The IDSS approach was applied to the Amhara region of Ethiopia, where the scarcity of resources and agro-environmental consequences are critical to agricultural productivity of small farm, to analyze the impacts of alternative agricultural technology interventions. Results show significant improvements in family income and nutrition, achieved through the adoption of irrigation technologies, proper use of fertilizer, and improved seed varieties while preserving environmental indicators in terms of soil erosion and sediment loadings. These pilot studies demonstrate the usefulness of the IDSS approach as a tool that can be used to predict and evaluate the economic and environmental consequences of adopting new agricultural technologies that aim to improve the livelihoods of subsistence farmers.
本研究使用综合决策支持系统（IDSS），在撒哈拉以南非洲的农场/村庄和流域尺度上，调查采用农业新技术的多维度影响。将IDSS作为一种综合建模工具加以应用，通过同时评估采用农业技术对粮食产量可持续增长和稀缺自然资源利用的生产、环境、经济和营养后果，有助于解决农业系统中的复杂问题。IDSS方法应用于埃塞俄比亚的阿姆哈拉地区，那里资源稀缺和农业环境后果对小农场的农业生产力至关重要，以分析替代性农业技术干预措施的影响。结果表明，通过采用灌溉技术、合理使用化肥和改良种子品种，在保持土壤侵蚀和沉积物负荷等环境指标的同时，可以显著提高家庭收入和营养水平。这些试点研究证明了IDSS方法作为一种工具的有用性，该工具可用于预测和评估采用旨在改善自给农民生计的新型农业技术的经济和环境后果。
