Saving Soil for a Secure Future

CLIMATE CHANGE SERIES

- Krishna Gupta

In the previous article, we had discussed the importance of Adaptation measures in Agriculture, so that food security can be attained and the sector is shielded from the adverse effects of climate change. An important aspect of this Adaptation strategy will include soil conservation and regeneration.

In addition to the long-practiced measures of soil conservation such as afforestation, control of overgrazing, better agricultural practices, contour and strip farming etc., there is a need to look at regenerating eroded soils and saline farmlands created by over-irrigation. Not only does soil conservation and regeneration improve crop yields, it also increases carbon absorption and prevents carbon dioxide emissions. It thus offers Adaptation and Mitigation benefits. Let us discuss this further.

Soil Conservation and Regeneration
With each passing year, climate risks are increasing in general. This is true of climate risks to soil conservation and regeneration as well. In addition to the extreme heat and loss of soil moisture, there are increased instances of water logging, higher salinity, changes in pests and plant diseases, increased wind erosion and more wildfires. Accordingly, farmers have to go beyond the traditional conservation measures outlined above.

Some of the Adaptation measures that need to be taken are:
