Last November, Maui voters through a ballot initiative passed a ban on the cultivation of genetically engineered crops. And now, a federal judge, Susan Mollway, ruled that the ban on genetically modified crops is “invalid and unenforceable” because it is preempted by state and federal law. The county’s ordinance creating the ban exceeded the county’s authority, she said. The county is a major center for research on GM crops due its year-round warm weather.

A commonly accepted approach for measuring the sustainability of agricultural products is the first step toward treating traded products differentially according to their sustainability. If we were able to measure sustainability, business stakeholders could optimize food production chains, consumers could demand products based on reduced environmental and social impacts, and policy makers could intervene to meet the growing demand for food in a context of environmental conservation, population growth, and globalization. We proposed to measure profit adjusted for the negative externalities of production as a promising single metric for benchmarking products in terms of their relative sustainability. The adjusted profit differences between different products are then assessed by means of the Bennet Total Factor Productivity (TFP) indicator and the Total Price Recovery (TPR) indicator to highlight areas for potential sustainability improvement. To illustrate the usefulness of the indicator-based approach, we assessed the relative sustainability of two Brazilian conventional soybean meal chains, non-genetically modified (non-GM) and genetically modified (GM) chains. Based on the results, we indicated potential areas for sustainability improvement. Sustainability issues included in the assessment were profitability, global warming potential, eutrophication potential, environmental toxicity, farmworker toxicity, consumer toxicity, deforestation, and loss of employment. Results showed that the non-GM soybean meal chain is more sustainable than the GM chain (higher adjusted profit due to higher TFP and favorable prices especially for outputs). However, both chains require joint efforts to address their economic, environmental, and social deficiencies.

The ability of scientific knowledge to contribute to public debate about societal risks depends on how the public assimilates information resulting from the scientific community. Bayesian decision theory assumes that people update a belief by allocating weights to a prior belief and new information to form a posterior belief. The purpose of this study was to determine the effects of prior beliefs on assimilation of scientific information and test several hypotheses about the manner in which people process scientific information on genetically modified food and global warming. Results indicated that assimilation of information is dependent on prior beliefs and that the failure to converge a posterior belief to information is a result of several factors including: misinterpreting information, illusionary correlations, selectively scrutinizing information, information-processing problems, knowledge, political affiliation, and cognitive function.

Here’s a question for our Dispatch readers: When is a GMO not a GMO? A proper science answer would go something like this: all agriculture (and really all life) has been genetically modified at some point either by humans or another species (e.g. bacteria or virus) so therefore everything is a GMO.

However, the world is not run through proper science, it’s run through politics and “concerns,” and this makes having a legal definition of GMOs difficult. Here in America, if a gene could have been introduced into a plant in nature, it can still be considered “organic” even if the process of getting that gene into the plant is highly scientific. A number of products that you are eating (and ironically they can be called organic) are created by a method that would horrify you—far more than what may concern you about GMOs.

China is now the top export market for U.S. agricultural products and is expected to continue growing. .

China has entered a period of transition that has slowed imports of some commodities and increased imports of others..

Future U.S. agricultural exports to China will be influenced by changes in consumption patterns, farm policies, and enforcement of import standards and regulations..

U.S. agricultural exports to China doubled from 2008 to 2012, growing to more than $25 billion in annual sales. China surpassed Japan, Mexico, and Canada to become the top export market for U.S. farm products. The share of U.S. agricultural exports destined for China rose from about 2-3 percent in the 1990s to 16-18 percent during 2012-14.

As a land-abundant country with highly productive farms, the United States is a natural trading partner for China, a country with limited per-capita supplies of cropland and water resources. A number of land-abundant countries export agricultural products to China, but the United States is the top supplier of China’s growing menu of agricultural imports, with a 24-percent share during 2012-13. The United States is China’s top supplier of imported soybeans, cotton, meat, cereal grains, cattle hides, distillers dried grains, and hay.

All genetically modified (GM) crops intended for use in food and feed must be assessed for their safety to humans and animals. The data and methodology used to conduct these assessments has been developed over many years. International organisations like the Food and Agriculture Organization (FAO) of the United Nations, the World Health Organization (WHO) and the Organisation for Economic Cooperation and Development (OECD) have been facilitating the harmonisation of food and feed risk assessment methodologies. The Codex Alimentarius Commission, established by FAO and WHO in 1963, has developed harmonised international food standards, guidelines and codes of practice and promoted coordination of all food standards work undertaken by international governmental and nongovernmental organisations.
