How can food security and climate change be addressed together by adopting practices that are climate smart?

Explain some of these practices.

Stop burning food to make energy.

Crop yields have approximately tripled due to the use of nitrogen fertilizers manufactured from natural gas via the Haber process. Populations growth has followed growth in the food supply. In that respect humans are no different from bacteria. Quite independent of the impact of the consequent carbon emissions on climate, the practice is unsustainable. Fertilizer production is declining in North America and moving offshore due to higher natural gas prices. Fertilizer is the highest single input cost for farmers. New technologies are being developed to make better use of fertilizer by varying application be local soil type and plant cover. As fertilizer costs rise, less will be used and yields will fall. There is a way out of the box, however. It is possible to manufacture nitrogen fertilizer locally by using renewable energy. A fertilizer plant that uses corn cobs as an energy source for fertilizer production has been built, but it supplies only a tiny fraction of total demand. This practice makes the carbon emissions a closed loop and provides a sustainable supply of fertilizer. More are needed.

I know a farmer that uses 3% of his land to grow an oilseed (canola) crop sufficient to run his machinery. His tractors have been modified to run on straight vegetable oil (SVO). He proud of the fact that he grows enough wheat to feed 20,000 people. This is a good practice because his food production is not dependent on increasingly scarce fossil fuels.

Global warming = more food security considering that longer warm seasons means longer growing seasons as well. This is well documented to occur during the warming period during the middle ages.

Also food security is more human controlled than environmental control. The US increased food security by developing a sophisticated agricultural infrastructure and engineering crops for higher yields. That's why less than 5% of the world's land mass (the continental US) can produce more than 25% of the world's food supply. To increase food security humanity needs to invest in developing sophisticated agricultural infrastructure in Africa, South America, and other continental areas of the world.

Food security is a agricultural and financial problem. It has been for years and has gotten worse due to restrictive laws from the UN and other entities. Just look at the San Joaquin Valley in California. It used to be the bread basket of the world. Now look at it. Its unproductive state is undeniably due to government regulation, rather than Climate Change or AGW. Look at Zimbabwe (Used to be Rhodesia). Rhodesia used to be the breadbasket of Africa. Now millions are starving in that country. Was that due to ACC or AGW? Obviously not! It was by government intervention.

Look to governments for the cause of hunger not AGW or ACC.

One way to reduce global warming is to reduce the amount of fuel we use on transportation of goods.

One way to reduce the amount of fuel we use on transportation of goods is to preferentially buy locally-grown foods, instead of foods shipped from half the world away (especially things delicate enough and far away enough that they're shipped by air).

And growing foods locally means that transportation disruptions will not cause significant local food shortages.

A few examples I can think of are Terra Preta soil practices , vertical farming methods, utilizing saline tolerant crops or bacteria to increase crop yields and available land for farming food and carbon neutral energy crops and Aquaponics methods.

Terra Preta soils or biochar are basically partially burned crop residues or burning junk crops that are turned into the soil which makes them retain nutrients better, improves microbial activity, conserves water and it sequesters carbon for centuries. Crop yields can improve up to 3-800 percent over conventional soils based on test plots....and it's scalable technology....backyard farming up to industrial size.

Aquaponics methods and vertical farming bring food production closer to urban areas where the food is needed and reduce fuel costs and CO2 emissions, water use, etc... Countries like Japan with little land available for conventional farming can build high rise buildings to grow crops year round with less waste to insects, disease, bad weather, etc.. We have a local company here in town...Growing Power.. that uses aquaponics to grow over a million pounds of food and 10,000 fish per year among other things from a 3 acre site...far more than conventional farming methods.Vertical farming methods takes that one step further and uses high rise buildings to grow crops year-round in cities or local areas reducing transportation costs and carbon emissions.

Saline tolerant crop methods can also open up an extra half million square miles of once useless land to grow food and energy crops....to feed people or animals or to be used in carbon neutral biofuel production.

All in all, these methods and others can address the need for food security in the world ....with some very low-cost and efficient methods...and at the same time mitigate carbon emissions for those who are concerned about AGW. Even if AGW was not a concern, they still provide a more efficient and effective means to produce food.

Well, worldwide crop production is at an all time high right now so more of the same I guess.

Explain some of these practices.
