 Figure SR-TM2. Level playing field.global supply    chains have been far less than optimal [ESAP; NAE; Global]. Building    countervailing negotiating power, such as farmer cooperatives and networks,    will be important to help resource poor farmers increase their share of    value captured.
 Agriculture  generates     large  environmental externalities    including accelerated loss of biodiversity and ecosystem services such as    water cycling and quality, increased energy costs and greenhouse gas    emissions, and environmental health impacts of synthetic pesticides [ESAP    Chapter 3; Global; NAE]. Many of these impacts derive from the failure of    markets to value and internalize environmental and social harms in the price    of traded agricultural and other products, or to provide incentives for    sustainability. AKST has great potential to reverse this trend, aiding in the    improvement of natural resource management and the provisioning of    agroenvironmental services.
