Use of genetically modified (GM) crops
One of the most up-and-coming techniques to ensuring global food security is the use of genetically modified (GM) crops. The genome of these crops can be altered to address one or more aspects of the plant that may be preventing it from being grown in various regions under certain conditions. Many of these alterations can address the challenges that were previously mentioned above, including the water crisis, land degradation, and the ever-changing climate. In agriculture and animal husbandry, the Green Revolution popularized the use of conventional hybridization to increase yield by creating high-yielding varieties. Often, the handful of hybridized breeds originated in developed countries and were further hybridized with local varieties in the rest of the developing world to create high yield strains resistant to local climate and diseases.

The area sown to genetically engineered crops in developing countries is rapidly catching up with the area sown in industrial nations. According to the International Service for the Acquisition of Agri-biotech Applications (ISAAA), GM crops were grown by approximately 8.5 million farmers in 21 countries in 2005; up from 8.25 million farmers in 17 countries in 2004.

Opposition to GM crops
Some scientists question the safety of biotechnology as a panacea; agroecologists Miguel Altieri and Peter Rosset have enumerated ten reasons why biotechnology will not ensure food security, protect the environment, or reduce poverty. Reasons include:


 * There is no relationship between the prevalence of hunger in a given country and its population
 * Most innovations in agricultural biotechnology have been profit-driven rather than need-driven
 * Ecological theory predicts that the large-scale landscape homogenization with transgenic crops will exacerbate the ecological problems already associated with monoculture agriculture
 * And, that much of the needed food can be produced by small farmers located throughout the world using existing agroecological technologies.

Based on evidence from previous attempts, there is a likely lack of transferability of one type of GM crop from one region to another. For example, modified crops that have proven successful in Asia from the Green Revolution have failed when tried in regions of Africa. More research must be done regarding the specific requirements of growing a specific crop in a specific region.There is also a drastic lack of education given to governments, farmers, and the community about the science behind GM crops, as well as suitable growing practices. In most relief programs, farmers are given seeds with little explanation and little attention is paid to the resources available to them or even laws that prohibit them from distributing produce. Governments are often not advised on the economic and health implications that come with growing GM crops, and are then left to make judgments on their own. Because they have so little information regarding these crops, they usually shy away from allowing them or do not take the time and effort required to regulate their use. Members of the community that will then consume the produce from these crops are also left in the dark about what these modifications mean and are often scared off by their 'unnatural' origins. This has resulted in failure to properly grow crops as well as strong opposition to the unknown practices.

A study published in June 2016 evaluated the status of the implementation of Golden Rice, which was first developed in the 1990s to produce higher levels of Vitamin A than its non-GMO counterparts. This strain of rice was designed so that malnourished women and children in third world countries who were more susceptible to deficiencies could easily improve their Vitamin A intake levels and prevent blindness, which is a common result. Golden Rice production was centralized to the Philippines, yet there have been many hurdles to jump in order to get production moving. The study showed that the project is far behind schedule and is not living up to its expectations. Although research on Golden Rice still continues, the country has moved forward with other non-GMO initiatives to address the Vitamin A deficiency problem that is so pervasive in that region.

Many anti-GMO activists argue that the use of GM crops decreases biodiversity among plants. Livestock biodiversity is also threatened by the modernization of agriculture and the focus on more productive major breeds. Therefore, efforts have been made by governments and non-governmental organizations to conserve livestock biodiversity through strategies such as cryoconservation of animal genetic resources.

Support of GM crops
Many GM crop success stories exist, primarily in developed nations like the US, China, and various countries in Europe. Common GM crops include cotton, maize, and soybeans, all of which are grown throughout North and South America as well as regions of Asia. Modified cotton crops, for example, have been altered such that they are resistant to pests, can grown in more extreme heat, cold, or drought, and produce longer, stronger fibers to be used in textile production.

One of the biggest threats to rice, which is a staple food crop especially in India and other countries within Asia, is blast disease, which is a fungal infection that causes lesions to form on all parts of the plant. A genetically engineered strain of rice has been developed so that it is resistant to blast, greatly improving the crop yield of farmers and allowing rice to be more accessible to everyone. Some other crops have been modified such that they produce higher yields per plant or that they require less land for growing. The latter can be helpful in extreme climates with little arable land and also decreases deforestation, as fewer trees need to be cut down in order to make room for crop fields. Others yet have been altered such that they do not require the use of insecticides or fungicides. This addresses various health concerns associated with such pesticides and can also work to improve biodiversity within the area in which these crops are grown.

In a review of Borlaug's 2000 publication entitled Ending world hunger: the promise of biotechnology and the threat of antiscience zealotry, the authors argued that Borlaug's warnings were still true in 2010, "GM crops are as natural and safe as today's bread wheat, opined Dr. Borlaug, who also reminded agricultural scientists of their moral obligation to stand up to the antiscience crowd and warn policy makers that global food insecurity will not disappear without this new technology and ignoring this reality global food insecurity would make future solutions all the more difficult to achieve."

Research conducted by the GMO Risk Assessment and Communication of Evidence (GRACE) program through the EU between 2007 and 2013 focused on many uses of GM crops and evaluated many facets of their effects on human, animal, and environmental health.

The body of scientific evidence concluding that GM foods are safe to eat and do not pose environmental risks is wide. Findings from the International Council of Scientists (2003) that analyzed a selection of approximately 50 science-based reviews concluded that "currently available genetically modified foods are safe to eat," and "there is no evidence of any deleterious environmental effects having occurred from the trait/species combinations currently available." The United Nations Food and Agriculture Organization (FAO) supported the same consensus a year later in addition to recommending the extension of biotechnology to the developing world. Similarly, the Royal Society (2003) and British Medical Association (2004) found no adverse health effects of consuming genetically modified foods. These findings supported the conclusions of earlier studies by the European Union Research Directorate, a compendium of 81 scientific studies conducted by more than 400 research teams did not show "any new risks to human health or the environment, beyond the usual uncertainties of conventional plant breeding." Likewise, the Organization for Economic Cooperation and Development in Europe (OECD) and the Nuffield Council on Bioethics (1999) did not find that genetically modified foods posed a health risk.
