Demand for yellow corn continues to increase every year and one of its main applications today is the biofuel production. Biofuels are a renewable energy source that is promoted as a solution to the problems of energy dependency and climate change. However, this use is generating direct competition with food production, which has raised concerns about its effects on the environment. food safety.
The impact of biofuels on food security
In the FAO report «The Future of Food and Agriculture: Trends and Challenges« FAO makes an in-depth analysis of the impact that the agricultural and energy sectors will have in the future. It is estimated that by 2050, Agricultural production should increase by 50% to meet both food and biofuel demand. In other words, increasing agricultural production for biofuels will inevitably affect food availability.
The effects of allocating large tracts of land to the cultivation of biofuel feedstocks are often negative for food price stability and local ecosystems. Competition between food and fuel production This puts pressure on agricultural markets, directly affecting costs and food security. In the case of corn, which is largely used to make ethanol, this conflict has pushed up prices and reduced the amount of production destined for human or animal consumption.
Deforestation and land use change
default
One of the serious consequences of the increase in biofuel production is the deforestation. In order to make more areas available for the cultivation of biofuel feedstocks, many regions are resorting to clearing forests. This has a counterproductive effect on climate change, since the felled trees no longer absorb carbon dioxide (CO2), a powerful greenhouse gas.
Over the past few years, tropical and subtropical regions have suffered a net loss of 7 million hectares of forest per year, while agricultural land has increased at a rate of 6 million hectares per year, according to FAO data. The land area used for agriculture is largely used for biofuel production rather than food production.
Deforestation to increase biofuel production not only affects forests, but also the biodiversity already water resources, which aggravates agricultural problems and the stability of ecosystems.
Competition between food and biofuel crops
The Committee on World Food Security (CFS) has warned that this growing competition for arable land may have a negative impact on less developed countries, where agricultural resources are limited and people suffer from higher rates of poverty and hunger. The CFS stresses that, especially since 2013, the conversion of land suitable for growing food to biofuel production has generated a unfair competition, which could exacerbate social and environmental problems.
In addition to causing food prices to rise, this competition for land has a direct effect on the rural povertyMany farmers prefer to grow biofuel feedstocks (which can offer higher returns) rather than food, since biofuels are often more profitable thanks to government subsidies. This could lead to a decrease in local food production and increase dependence on imports to meet the population's food needs.
Possible solutions: international policies and new technologies
Not all biofuels are created equal, both in terms of Energy Efficiency as an impact on agriculture and food security. Technologies of second generation, for example, using agricultural waste or non-edible biomass, represent an opportunity to reduce competition between food and energy. However, their large-scale implementation is still in the early stages of development.
To mitigate the impact of biofuels on food security, Strong international policies are needed that regulate land use, promote the development of advanced biofuel technologies and facilitate investment in sustainable agriculture. Some options include the use of degraded lands for growing biofuels or crop rotation that allows farmers to balance food production with energy production.
The future of biofuels must be linked to a combination of cleaner technologies and sustainable agricultural policies that protect global food security. Biofuel promotion must be done cautiously, taking into account both the energy and food needs of a growing global population.
