Forewarned is forearmed they say and the world cannot get any louder with the warning signs it has been sending. Man is highly likely to find himself in a situation where bare essentials such as shelter, food and most importantly water are unavailable. This calls for action that will see man adapt and be able to survive in the near future.
Climate change has plunged man into a predicament whose ramifications are far reaching. To understand this, one must first comprehend the disparity that now exists between the amount of food needed by the seven billion occupants of earth versus the ability to produce it. For optimum sustenance, the world needs an estimated 12 trillion in calories daily yet the population keeps increasing and the adverse changes in climatic conditions are only aggravating the food situation further. All hope now lies with science and technology to reverse or at least abate the situation.
SHIFT FOCUS TO SEED PRODUCTION
Drastic climate change brings with it undesirable results such as carbondioxide pollution in the air, salty conditions in the soil and destruction to the all important ozone layer. It is almost impossible to imagine anything growing in such conditions yet research can still save mankind. Science and technology can turn to genetically modified seeds designed to withstand harsh climatic conditions such as these. In addition the seeds will also be able to withstand droughts, frost, insect attacks and flooding. Science and technology bears hope for man to survive in coming times but this can only work if the production and distribution of the said genetically modified seeds is governed by stringent policies and laws enacted by international bodies. No single private organization should be given autonomy over this important project as this will present a chance to hoard and exploit farmers for selfish reasons.
It has now emerged that changes in climate will affect different parts of the world differently especially depending on their latitude. Certain parts of the world will end up with rich land that can be harnessed for farming but others will not be so lucky. Russia, the U.S. and China may be among the lucky ones while India, Africa, Europe and South America may end up with deplorable land that is no good for farming. Again laws will be required to control equittable food distribution to all parts of the world. Farmers will be advised to focus more on legumes and other crops with nitrogen fixing properties. Cover crops will be important to help hold and protect the soil during harsh weather. The use of periphery plants or fences will help in keeping away destructive insects and animals. All these methods are natural and eliminate the harmful use of poisons and pesticides which only worsen the environmetal degradation.
WATER HARVESTING AND STORAGE
Water is life. In the harsh climatic times ahead, farmers will have to maximise on whatever little water they have. Rainwater will be instrumental in food production and better water harvesting and storage methods will have to be adopted. Recycling used water will help save on fresh water and irrigation methods will be the best way to nourish growing crops. Technology will play a key role in calculating just how much water is required for specific sizes of land.
STRIKING OUT BIOFUEL AND MEAT
It is no longer economically sensible to produce meat as too much goes into it and very little benefit comes out. Depending on biofuel as an energy source is also an unwise move in such times as it utilises important food sources as its raw materials. The idea that there might be a food shortage in the future has led producers to increase food prices. Internationally recognised rules should be employed to limit the power of banks in as far as predicting and acting on food futures go. With all these controls in place, man’s food security in the future will be ensured.
