Various methods and tools have been developed to quantify energy supply security; however, there is no ideal framework to measure energy security, as the concept is multifaceted and context dependent. Energy supply security has always been an extremely important issue for European Union (EU)...

Crop diversification is a farm level strategy to augment income, improve food security, and mitigate risks attributable to climate and market shocks. We use three-waves (2011/12 to 2016/17) of nationally representative repeated cross section surveys to study the impact of crop diversification on...
