Strategies to avoid impacts of climate change on food crops (ResearchGate / Jayanta Dutta / Willem Van Cotthem / Veeresh Hogarnal)

On August 21, 2012 Dr. Jayanta DUTTA, (Uttar Banga Krishi Vishwavidyalaya · Agricultural Economics) launched an interesting discussion on ResearchGate :

I had the honour of participating in that discussion by posting the following message :

“Decision-makers and responsible authorities, in particular FAO, WFP and the Ministries of Agriculture, should build strategies taking into account the lessons learned in success stories of reducing irrigation of food crops. Moreover, the universal movements of individuals and groups to produce food at the non-industrial level (container gardening, guerilla gardening, vertical gardening, sack gardening in slums and refugee camps, etc. …) show that modern methods and technologies have been developed to minimalize the effects of climate change. Small-scale farmers are often our front-men in adaptation to environmental problems. It suffices to help them to apply “their strategies”.”

A new valuable answer was sent by :

Veeresh Hogarnal · University of Agricultural Sciences, Raichur

“The impact of climate change with reference to rainfall distribution is very much experienced in recent years particularly in India. However, serious attempts should be made to know whether it has made any decline in the quantum of rainfall!!. There is erratic distribution of monsoon rains, I mean decrease in number of rainy days while there is increase in its intensity…this resulted in drought and flood like situations in different parts of the country. Therefore, the urgent need to mitigate the impact of climate change on crop production is to take up large number of soil and moisture conservation measures at micro level. This practice definitely recharge the ground water bodies which significantly benefits small and marginal farmers. They can withstand extreme drought conditions in subsequent years. Next best approach is to introduce Integrated Farming System comprising of agriculture, horticulture, forestry, animal, poultry, fishery etc. to sustain the livelihood of farmers with assured economy even in a small piece of land. After ensuring this to the farmers, they will be in a position to experiment with the different adoption strategies. Scientist will get ample time to develop drought tolerant varieties etc.”


I am looking forward for new contributions to this discussion.
