Development of an Environmentally Advanced Basin Model in Asia

The second issue is environmental problems resulting from the spread of modern agricultural methods. Since the Green Revolution, Asian nations have greatly increased land productivity through the widespread use of modern agricultural methods such as the adoption of highyielding varieties and chemical fertilizers, in response to population growth. However, modern agricultural methods that promote uniform cultivation simplify ecosystems and are harmful to regional biodiversity. This in turn erodes regional characteristics and weakens the ability of regions to adapt to external change, which carries the risk that a major environmental change could result in catastrophic damages.

Contribution of ICT Monitoring System in Agricultural Water Management and Environmental Conservation

Recently, ICT based monitoring system is popularized in some agricultural areas. In such area, farmers can obtain their paddy conditions by using smart phone without going to the paddy. In this study, the effect of ICT based monitoring system on water and labor saving, and nutrient loads reduction was evaluated. Then, cost/benefit of monitoring system installation was compared. Finally, how to promote ICT systems in agricultural engineering field was discussed based on the characteristic of agricultural water management system.
