SUBJECT: Climate Change Impact on Food Security
Introduction and Summary of Recommendation
This memorandum presents options available to you The Climate Change Committee
(CCC) the possible solutions for mitigating climate change impacts on food security. Long-term
changes in weather and temperature are referred to as climate change. It is clear that historically,
those who survive off agriculture have created their adaptations to climatic change. The present
climate change rate will alter recognized variability patterns, putting humans in circumstances
they are not prepared for. We recommend that you take the following steps:
Monitor weather and climate, including variables of climate change and food security
data assessments, and observing climate effects on the rural economy are among scientific
responses to the global warming crisis. Bremer and Meisch (2017) indicate that it is vital that
data from early warning systems including climate change forecasts be made accessible to
disadvantaged groups so they can make informed decisions on such stresses. Leisner (2020)
points that to minimize system failures and severe food security consequences, all participants in
the food supply chain must have access to trustworthy climate change information.
The management of agricultural water is one of the recommendations for mitigating food
insecurity caused by climate change. Bullock et al. (2017) say with or without climate change,
, the water supply globally is in jeopardy. Today, one in three individuals suffers from water
scarcity. Unsustainable usage is straining global supplies while modern lifestyles have raised per
capita water consumption (Bullock et al., 2017). Climate change-induced water scarcity and
variations in water availability threaten both irrigated and rain-fed agricultural productivity
globally. Sorensen et al. (2018) suggest that to increase hydraulic performance and regulate
salinity, agricultural water productivity, and operational storage should be optimized.
Investing in the widespread adoption of best mitigation practices in the agriculture and
food industry could thus have multiple paybacks for food and nutrition security (Clapp, Newell
& Brent, 2018). It also contributes to sustainable food price stability, creating new jobs in the
agricultural industry, and boosting the sustainable development of vulnerable rural livelihoods
(Fouilleux, Bricas & Alpha, 2017). It might be accomplished by lowering CO2 emissions,
slowing deforestation and land conversion, improving wildfire management, and adopting
substitutes to burning crop wastes after harvest. Waldron et al. (2017) say it is feasible to
mitigate the effects of climate change affecting food security when such measures are made.
Another important suggestion is to promote conservation agriculture. By using
mechanical tools to break layers of soil, conventional tillage hand hoes are the simplest. Tractor-
drawn plows, disk harrows, and rotary cultivators are used in mechanized soil tillage. It improves
soil fertility by mineralizing soil nutrients and making them more readily available to plants
(Ujunwa, Okoyeuzu & Kalu, 2018). For long-term soil health, plowing and mechanical
cultivation must be avoided. Soil compaction and crust development occur due to structural
deterioration of soils, making a reduction of tillage the logical solution (Tumushabe, 2018).
Agrochemicals organic nutrients should be delivered at optimum levels, avoiding the disruption
of biological processes.
