Energy efficiency measures were proposed for each agricultural system and presented in an overview report. [6] A synthesis and summary report on drivers and stakeholders of energy efficiency in agriculture, and potential of energy saving hours was produced.
Climate-smart agriculture (CSA) (or climate resilient agriculture) is a set of farming methods that has three main objectives with regards to climate change. [ 1 ] [ 2 ] Firstly, they use adaptation methods to respond to the effects of climate change on agriculture (this also builds resilience to climate change ).
the amount of energy contained in the final ethanol product; the amount of energy directly consumed to make the ethanol (such as the diesel used in tractors) the quality of the resulting ethanol compared to the quality of refined gasoline; the energy indirectly consumed (in order to make the ethanol processing plant, etc.).
It may therefore decrease global food security unless action is taken to 'decouple' fossil fuel energy from food production, with a move towards 'energy-smart' agricultural systems including renewable energy. [69] [70] [71] The use of solar powered irrigation in Pakistan is said to be a closed system for agricultural water irrigation. [72]
There are numerous effects of climate change on agriculture, many of which are making it harder for agricultural activities to provide global food security. Rising temperatures and changing weather patterns often result in lower crop yields due to water scarcity caused by drought , heat waves and flooding . [ 5 ]
The Green Revolution, or the Third Agricultural Revolution, was a period of technology transfer initiatives that saw greatly increased crop yields. [ 1 ] [ 2 ] These changes in agriculture began in developed countries in the early 20th century and spread globally until the late 1980s. [ 3 ]

Energy efficiency—using less energy to deliver the same goods or services, or delivering comparable services with less goods—is a cornerstone of many sustainable energy strategies. [ 36 ] [ 37 ] The International Energy Agency (IEA) has estimated that increasing energy efficiency could achieve 40% of greenhouse gas emission reductions ...
