Food security - a global concern

The world’s population is projected to grow to nearly 10 billion by 2050 – an increase of 2 billion people from today – with the population of sub-Saharan Africa alone expected to double. As the global population continues to increase, countries have to find new ways to grow more food. 

The Green Revolution - brought the use of fertilizers and pesticides, irrigation, and high-yield crop varieties into commercial farming. Thanks to these techniques, from the 1960s to the 1990s, rice and wheat yields in Asia doubled. In addition, the New Green Revolution involves using different seeds to help specific areas experiencing the impact of global warming, such as drought and flooding. There is also a focus on improving the nutritional value of crops, rather than just providing more calories. As a result, the New Green Revolution should help the most impoverished areas of the world.

Biotechnology, known as the process of selective breeding or genetic modification(GM) of plants and animals, can help improve crop quality and production. However, these processes must remain ethically and environmentally adequate.
