Energy Needs and Greenhouse Gas Emissions in Agriculture
While one of the main contributors, agriculture is also majorly affected by the climate crisis, which is why approaches for adaptation and mitigation are urgently necessary. Addressing emissions and global warming potential in agricultural activities is fundamental in order to reduce its impact. While creating new opportunities for food security, seeking clean energy solutions can also help combat climate change. Detecting the gaps for innovative opportunities requires first a thorough knowledge of the fundamentals of energy flows and greenhouse gas emissions (GHG) in 
GHG Emissions in Agriculture
GHG emissions from AFOLU activities have increased by almost 100 percent in the last 50 years, accounting for 25% of the total net GHG emissions between the years 2007-2016. However, if emissions associated with pre-and post-production activities in the global food system are included, the emissions are estimated to reach up to 37 percent of global anthropogenic GHG emissions. CO2 accounts for 13 percent, methane (CH4) for 44 percent, and nitrous oxide (N2O) for 82 percent. The main emitters are livestock-related enteric fermentation (40 percent), manure left on pasture (16 percent), synthetic fertilizers (13 percent), paddy rice cultivation (10 percent), manure management (7 percent) and the burning of savannahs (5 percent).
Energy within Production and Processing
About 30 percent of global energy is consumed in the agriculture, forestry and land use (AFOLU) sector (2011). Energy is necessary at every level of the food value chain including the production of agricultural inputs, agricultural production in the field, food processing, transportation, marketing and consumption.
