Global Overview: Definition
Defined: Various agricultural and food production techniques that aim to improve agricultural conditions and produce better food. Modern : Identification and transfer of specific gene(s) that create(s) a desired quality in a plant. More precise way to produce plants with certain beneficial characteristics such as insect protection or better nutrition. Photos courtesy of Wayne Parrot, PhD, University of Georgia
Global Overview: Adoption
Global : Adoption 60-fold increase in acreage, 1996 to 2006 In 2006: 252 million acres (102 million hectares) 22 countries 10.3 million farmers Traits expressed in crops: Bt (insect protected) HT (herbicide tolerant) VR (virus resistant) %Global Crop Acreage: 64% soybean 38% cotton 18% canola 17% maize
Global Overview: Regulation and Safety
Global : Regulation and Safety Deemed safe by scientific and regulatory authorities globally for food, animal feed, and environmental safety
Global : An Example of Safety Assessment Cooperation Assessing Allergenicity of Genetically Modified Foods 2000: Decision tree adopted 2001: 28 experts reaffirmed and recommended integrating emerging research and modifying, as needed Decision Tree is utilized worldwide

Global : Challenges to Cooperation regarding Trade Regulation Cartagena Protocol on Biosafety Designed to address biodiversity Biotech crops and seeds require approval and notification prior to importation Complexity and extended scope raise interpretation, implementation, and resource challenges 195 nations have ratified the Protocol Critics, including the US, have concerns that the Protocol is not science-based
Understanding Agriculture, Food, and Health in Developing Nations
Agriculture, Food, and Health in Developing Nations AGRICULTURE plays critical role: Engine of ECONOMIC GROWTH Employer to nearly ½ labor force Enhancing agricultural productivity to include better quality, quantity and consistency means: BETTER DIETS HIGHER INCOMES 1% increase in yield can increase income by 100% for 44% of Sub-Saharan Africans
: Impact of Improved Productivity on Human Health REDUCED PESTICIDE USE PRODUCE MORE CONSISTENT FOOD SUPPLY HIGHER FARM/ FAMILY INCOME TRANSITION TO USE OF SAFER PESTICIDES HUMAN HEALTH STIMULATION OF LOCAL ECONOMIES IMPROVED WATER QUALITY IMPROVED AIR QUALITY PRODUCE MORE FOOD/NUTRITIONAL VALUE PER CROP REDUCED SOIL TILLAGE IMPROVED SOIL QUALITY
Hunger, poverty, and disease are interlinked, with each contributing to the presence and persistence of the other two. World Health Organization, 1997 Agriculture, Food, and Health in Developing Nations 854 million hungry people in world with 820 million (96%) of those individuals in developing countries In Africa: 1/3 undernourished 1/4 of children underweight 1/3 of children stunted Population growth compounding problem! 40% more food needed from agriculture to meet needs of projected population
Food, Agriculture, and Health in Developing Nations Many BARRIERS to addressing hunger and malnutrition through increasing agricultural production Failure to address agricultural production, however, would undermine selfsustainability Fortunately biotechnology does not rely on economies of scale. The power of biotechnology is delivered via the seed itself.
Developing Nations: Adoption
Developing Nations: Adoption 2006 11 of 22 countries with biotech crop acreage were developing nations 40% global acreage in developing nations (vs. 14% in 1997) Of 10.3 million farmers who planted biotech crops in 2006: 90% or 9.3 million were small, resourcepoor farmers from developing countries Increased income from biotech crops contributed to poverty alleviation. Most reside and work in China, India, the Philippines, and South Africa.
Developing Nations: Benefits
Developing Nations: Solving Problems is making and has the potential to make further essential contributions to resolving certain food and agricultural issues in the developing world Human Health Environmental Economic Because trace minerals are important not only for human nutrition, but for plant nutrition as well, plant breeding holds great promise for making a significant, low-cost, and sustainable contribution to reducing micronutrient, particularly mineral deficiencies in humans, and may have important spinoff effects for increasing farm productivity in developing countries in a way that is environmentally-beneficial. (Bouis, Graham, and Welch, 1999)
Developing Nations: Human Health Benefits Improved nutrition Golden rice Golden mustard oil Higher protein potato Micronutrient-enhanced cassava, rice, etc.
Developing Nations: Human Health Benefits Reduced toxin formation, in the field and post-harvest Reduced mycotoxin formation in insectprotected (Bt) varieties Varieties developed to produce less naturally-occurring toxin
Developing Nations: Human Health Benefits Increased food production Disease and pest resistance Resulting yield increases
Developing Nations: Human Health Benefits Farmer health Reduced pesticide exposure during spraying Economic gains translate into better diets and health care
Developing Nations: Environmental Benefits Global Reductions in Pesticide Use 224 million kg (6%) active ingredient, 1996-2005 Environmental Impact Quotient (EIQ) 15.3%, 1996-2005 Human health impact? Reduce farmer exposure. Improve air and ground water quality. Improve diets through increased net income to farmer.
Developing Nations: Environmental Benefits (continued) Reductions in Greenhouse Gas (GHG) Emissions Less fossil fuel used to spray pesticides and/or till the soil 962 million kg CO 2 Equivalent to 427,556 average family cars More organic carbon sequestered in soil with no-till and reduced-till systems 8,053 million kg CO 2 Equivalent to 3,579,298 average family cars Human health impact? Improve air quality. Improve diets through increased net income to farmer.
Developing Nations: Economic Benefits 2005 direct global farm income benefit*: $5 billion 2005 direct developing nations farm income benefit*: $2.75 billion Human health impact? Allow farming families to eat better. Channel resources into local economy, allowing non-farming families to eat better. * Farm income benefit accounts for impact on yield, key costs of production (seed, crop protection, fuel, labor), crop quality, facility of planting 2nd crop within a season, price changes
Developing Nations: R&D
The reality is that poor countries have vibrant programs of public biotech research. Joel Cohen, International Food Policy Research Institute, 2004 Developing Nations: Research and Development Research goals relevant to developing nations: Reduce need for agrochemicals Pest and disease resistance Increased tolerance to drought and saline soils Prolonged shelf life and other enhanced product characteristics Improved nutritional value R&D is active worldwide in specific countries, and through international collaborative research groups

Case Study: South Africa ECONOMIC Farm income $76 million, 1998-2005 Makhatini Flats cotton farmer survey ( 98-01) Gross margin increase: $86-93/hectare Revenue, yield, harvest labor, seed cost Pesticide cost, pesticide spray labor Social implications for female farmers supporting families ENVIRONMENTAL EIQ ranged from 7% for HT soybean to 0.44% for HT maize Walking with a knapsack sprayer on his back, a farmer has to cover a distance of 10-20 km to apply pesticide to one hectare of cotton. Water has to be carried by hand from communal water sources, and in dry areas clean water is a very scarce commodity. Illness due to exposure to pesticides is not uncommon among small-scale farmers.
