Developing countries in South and Southeast Asia primarily consist of agrarian economies. However, the agriculture sector in this region is vulnerable to climate change and faces increased water scarcity, soil degradation and water pollution, partially due to conventional farming techniques. A significant transformation is needed to (a) achieve food security, (b) meet the projected 70% increase in market demand of agriculture production by 2050, and (c) respond to climate change. Precision Agriculture (PA) would be an appropriate strategy to achieve such a transformation. This project aims to promote PA techniques in proposed countries, where paddy is a common crop. PA techniques, which include technologies like Unmanned Aerial Vehicles (UAVs), can help to improve agricultural productivity through the management of fertilizers and irrigation, pests/diseases control, and yield estimation. Specifically, UAVs provide low-cost, high spatio-temporal data for users to treat a field as a heterogeneous entity and make appropriate interventions to increase productivity. The aim of the proposed project is to (1) develop the technical capacity of multiple stakeholders (Farming Industry-Academia-Government and farming practitioners) to use UAVs for PA; (2) improve the sustainability of paddy cultivation using UAV-based information and decision making. This project will transfer the knowledge about common challenges and effective solutions and lead to best practices for PA using UAVs.
