Role of Remote Sensing for Crop Production, Food Security, and Sustainability of Ecosystems

Abstract

Remote sensing has a vital role in monitoring, analyzing, diagnosing, and predicting the dynamics of ecosystems for food and environmental decision-making at various scales. Spatio-temporal information of ecosystems is the important basis for such as precision crop management, yield assessment, mitigation of greenhouse gas emission, and adaptation to global climate change. Since the issues concerning agriculture, ecosystems and environment are strongly linked each other due to bio-geo-physical processes as well as globalization of market economy, the consistent earth observation is required for such applications. Combination of remote sensing, geoinformation and modeling may be the most promising approach. Inter-disciplinary, inter-agency, and international collaborations are needed towards better solutions for ecosystem problems.
