THE AGE OF HYPERCHANGE •Our world is transforming around us quickly. •Entire new industries and technologies are now regular parts of our lives. •Technology, globalization, and limiting natural resources are changing the way we make decisions. •We can Ignore them at our own risk

Weather Monitoring

GCMs are constantly improving, and converging to observations. Reichler and Kim , BAMS

Temperature projections are much better than precipitation projections. Climate Impacts Group

Due to model uncertainty, an ensemble of models is more accurate than any single model. Climate Impacts Group (2007)

Operational Use Technology

  

Let us clearly identify what these gaps are? What needs to be done to bridge these gaps? What kind of procedural changes, platforms, mechanisms and institutions are required? How do we augment the existing capacities to take the technology from research labs to farms and operational managers’ desk? How do we optimally use the financial resources available, and at the same time leverage these resources? What kind of policy changes do we require?

Change of perception

Building a culture of decision making on scientific principles

Greater emphasis on inter-institutional collaboration

Continuous capacity development: at all levels including: in service trainings and at farm level

Greater interaction with international community

Review of the curricula at the graduate level

Knowledge Intensive Development

Knowledge Extensive Development

Ignore Technology at your own RISK Convergence through Collaboration and effective Coordination is IMPARATIVE
