2 The Problem: Environmental degradation in the developing world impacts political and social instability Rwanda, 1994 -Population explosion -Shortage of cultivatable land -Heavy deforestation -Poor soil conservation  Food production shortage  Food-energy deprivation coincides with ethnic strife  Hutu refugees have devastating environmental, social, and political impact on the Democratic Republic of Congo. (Gasana 2002)

5 The Solution: Sustainable Agriculture We must meet the needs of the present without compromising the ability of future generations to meet their own needs. Three Goals: - Environmental health - Economic Profitability - Social and Economic Equity Requires: - Stewardship of both natural and human resources - Interdisciplinary efforts in research and education - Participation of farmers, farmworkers, consumers, policymakers, etc. (University of California 1997)

6 Agricultural Biotechnology: Potential Component of a Sustainable System? Understanding Agricultural Biotechnology HT crops – herbicide tolerant varieties genetically engineered to resist certain weed killers. Bt corn – varieties engineered to be resistant to certain insects by expressing a natural toxin in plant cell tissues. Source: (Benbrook 2002)

7 Does agricultural biotechnology fulfill the goals of sustainability? Goal #1: Environmental Health Potential Benefits  HT crops may reduce herbicide use  Roundup is one of the safest herbicides for mammals  Roundup-Ready soybeans increase adoption of no-tillage planting systems, which reduces soil erosion  Bt corn may reduce pesticide use  Bt toxins safer than conventional insecticides for mammals Risks  HT crops actually increase herbicide use  Roundup decreases nitrogen fixation  Genetically modified plants may be more vulnerable to certain diseases and insects  Increased “selection pressure” increases possibility of new genetically resistant pest population  Increased chance of harm to non- target species  Gene flow may yield new virus resistant weeds  Human health risks  Reduced crop diversity (Thrupp 1997) (Benbrook 2002)

8 Does agricultural biotechnology fulfill the goals of sustainability? Goal #2: Economic Profitability Potential Benefits  There is little evidence to suggest that biotechnology could be implemented cost efficiently in the developing world. Risks  Developing countries lack the resources to support GMO’s: - high chemical inputs - market factors  The high variation in crop yields produced by genetic modification hurts subsistence farmers the most (Gould and Cohen 1999) (Rosset 2000)

9 Does agricultural biotechnology fulfill the goals of sustainability? Goal #3: Social and Economic Equity Potential Benefits  Greater food security  Increased social and political stability Risks  Concentration of the tools of biotechnology in the hands of a few powerful corporations may restrict market access and increase economic disparities (NPR 2000)  Small farmers lack bargaining power (Rosset 2000)

10 Lessons from the Green Revolution: Agricultural trends in the Developing World India – adoption of high yield seeds increased fertilizer use per acre by six-fold. So far, 6% of agricultural land has been rendered useless. Philippines – During the 1980’s, rice yield increased by 13%, fertilizer use by 21% following the adoption of high-yield seeds.  High volumes of fertilizer causes long-term soil degradation followed by decreased yields

11 Sustainable Alternative: Agroecology “Alternative farmers often produce high per acre yields with significant reductions in costs per unit of crop harvests.” National Research Council Crop Rotation - suppresses certain pests - replenishes soil nutrients Soil covers - may attract good insects, repel bad insects - holds soil nutrients in place - increases water infiltration and water holding capacity of soil Tillage reduction - decreases erosion Irrigation management - reduces run-off Source: (Sanet 2000)

12 Agroecology in the Developing World Brazil – Green Manures India – Water-Salt management Kenya – Push-Pull technique Cuba – Small-farm model

13 Conclusion An agroecological approach which utilizes the natural resources already present in a given area is the most efficient long-term approach to the problem of resource management.
