The 4.0 revolution

Citrus is India's third-largest fruit crop, boosting production of 1.07 million hectares to 10.48 million tonnes (2013-14). Therefore, yields of 20-25 tonnes/ha have been recorded by some progressive growers, but average productivity is 9.78 tonnes/ha. In other countries where citrus is grown, these numbers are 40-50 tonnes, and the production life in orchards is much longer. High-strength cultivation with automatic fertilization has contributed significantly to the commercial citrus cultivation revolution in many countries.

Climate change is a serious environmental challenge that could undermine the drive for sustainable development. The global mean surface temperature has increased by an average of 0.6° Celsius (°C) over the last 100 years, largely due to the accumulation of greenhouse gases in the atmosphere (IPCC, 2002). Most of this change has occurred in the past 30 to 40 years, and the rate of increase is accelerating. These rising temperatures will have significant impacts at a global scale and at local and regional levels.

Optical Networks: A Practical Perspective - Part 40. This book describes a revolution within a revolution, the opening up of the capacity of the now-familiar optical fiber to carry more messages, handle a wider variety of transmission types, and provide improved reliabilities and ease of use. In many places where fiber has been installed simply as a better form of copper, even the gigabit capacities that result have not proved adequate to keep up with the demand.
