Stop Food Loss to Counter Climate Change

Artificial refrigerant gases cause global warming... and so do gases from wasted food
India has the world’s largest footprint in cold stores. Recent estimates indicate that over the last few decades we have created 130 million cubic metres of refrigerated warehousing space. Most importantly, 97% of these happen to be users of natural refrigerant gases – in effect this is the world’s largest collection of users of ammonia based refrigeration. This is not a petty matter, as most of the developed world has cold stores that deploy artificial refrigerants. Unlike ammonia, these artificial fluids - Hydrochlorofluorocarbons (HCFCs) and Hydrofluorocarbons (HFCs) - either caused Ozone depletion or are negatively impacting Global Warming.

In Europe alone, reports indicate that almost 50% of their food chain refrigeration is using such gases with a thousand times higher global warming potential (GWP) than CO2. Ammonia on the other hand, extensively used in India, has zero GWP.

High Technology in Agriculture

Use of technology in agriculture is normally interpreted as technologies that go into on-farm machinery. However, there are many more high-tech applications, involving various sciences, which have come into regular use in agriculture.
Drones are used in farming for various reasons
For example, India has a program called CHAMAN which uses satellite based remote sensing information or geo-informatics to manage crop forecasting. High tech systems, that use overhead Drones, chemistry labs and spectrograph analytics are part of agriculture and are used to manage crops and diagnose soil health. Spread your gaze wide, and you will find almost every possible form of science being applied in the field of agriculture.
