Climate change in agriculture
Climate change consists of a series of modifications over time of weather patterns, such as rainfall and temperature, among others. Weather events such as cold fronts, hurricanes, frost, extreme rainfall and also drought or excess humidity occur.
The impact of global warming on agriculture: droughts and extreme temperatures
These changes could have been generated naturally, by variations in the solar cycle or produced by human activity. Due to this, global warming is occurring, generated by the accumulation of gases in the earth’s atmosphere, as a consequence of deforestation and large CO2 emissions.
Increased drought and extreme heat are some of the climatic changes that most affect agriculture and are probably the greatest threat to crops and civilization.
Strategies for sustainable agriculture in the face of climate change
However, the demand for food is constantly growing, as the population is expected to grow and climate change is precisely the cause of decreasing yields in agriculture.
There are currently many initiatives in the agricultural sector to adapt current agriculture to the impact of climate change. The main strategy is the reduction of greenhouse gas emissions (CO2, CH4 and N2O) common in the energy, mining, agricultural and livestock industries, through renewable energies, thus reducing gas emissions.
Agricultural practices to mitigate climate change
There are also other strategies which are taken into consideration to reduce gas emissions, such as the conservation of agricultural ecosystems as CO2 sinks, also the optimization of water resources by rotating crops and finally the use of disease resistant crops, leading to less use of agrochemicals.
