Drought Assessment and Monitoring for Sustainable Production of Tef Crop and Land Management in Ethiopia Using Geoinformation Science

摘要

Agricultural sustainability has the highest priority in all countries, whether developed or developing. Geoinformation Science is gaining importance as useful precision farming Science in sustainable agricultural management and development. This research is intended to demonstrate the applicability of these tools in suitability zoning, information extraction and mapping for agricultural development of tef crops in Ethiopia. The crop species is indigenous and has its centers of both origin and diversity in Ethiopia. The solution for providing food security to all people of the world without affecting the agro ecological balance lies in the adoption of new research tools, particularly from aerospace Remote Sensing, and combining them with conventional as well as frontier technologies. Climate change variability and uncertain rainfall distribution in rainfall-dependent farming areas, especially in arid and semi-arid ecosystems that have drought occurs every two years become one of the most important natural disasters and often results in serious economic, social, and environmental crises. This paper describes the process and purpose of creating these maps is in an attempt to locate regions of Ethiopia that are suited for current tef varieties or improved varieties that mature within a time frame. High spatial resolution has proven to be an important tool for crop discrimination, especially if considered that Geoeye-1 performed better than Rapid eye. This result focuses on identifying drought beginning, end, spatial extent, and severity of the drought in a given region and is based on scientific reasoning. Once the analysis is conducted it is beneficial in developing drought policies, early warning monitoring systems, mitigation strategies, sustainable production management/development and preparedness plans.
