The Cost of Biotechnology Regulation in the Philippines

This paper identifies direct costs and opportunity costs of bio-safety regulation for four transgenic products in the Philippines: Bt eggplant, Bt rice, ringspot-virus resistant papaya, and virus resistant tomatoes. It finds that direct regulatory costs while significant, are generally smaller than the research costs for technology development. However, both research and regulatory costs are overshadowed by even a relatively brief delay in product release, which may occur due to unexpected regulatory delays.Food Consumption/Nutrition/Food Safety, Research and Development/Tech Change/Emerging Technologies,

THE DISTRIBUTION OF BENEFITS RESULTING FROM BIOTECHNOLOGY ADOPTION

The purposes of this study are two-fold: (1) to estimate the size of total benefits arising from the adoption of agricultural biotechnology, and (2) to measure the distribution of total benefits among key stakeholders along the production and marketing chain, including U.S. farmers, gene developers, germplasm suppliers, U.S. consumers, and the producers and consumers in the rest of the world. This study focuses on the benefits that resulted from the adoption of herbicide-tolerant soybeans as well as insect-resistant (Bt) and herbicide-tolerant cotton in 1997. In this analysis, various data sources are examined for measuring the farm-level effects of adopting biotechnology and the resulting benefit estimates are compared. The size and distribution of the benefits arising from the adoption of biotech crops vary significantly, depending on the farm-level effects obtained from the various data sources and the supply and demand elasticity assumptions for the domestic and world markets. Estimates of the benefits derived from farm-level impacts that isolate the effects biotechnology appear to be the most plauible. This study does not lend support to the popular belief that U.S. farmers received at least one-half, or as much as two-thirds, of the total benefits realized from the adoption of biotechnology. In contrast, the results of this study indicate that in 1997, U.S. farmers realized considerably less than half of the total benefits. The bulk of the benefits appear to have gone to the gene supplier, seed companies, U.S. consumers, and the rest of the world.Research and Development/Tech Change/Emerging Technologies,

Optimization of Low-Thrust Spiral Trajectories by Collocation

As NASA examines potential missions in the post space shuttle era, there has been a renewed interest in low-thrust electric propulsion for both crewed and uncrewed missions. While much progress has been made in the field of software for the optimization of low-thrust trajectories, many of the tools utilize higher-fidelity methods which, while excellent, result in extremely high run-times and poor convergence when dealing with planetocentric spiraling trajectories deep within a gravity well. Conversely, faster tools like SEPSPOT provide a reasonable solution but typically fail to account for other forces such as third-body gravitation, aerodynamic drag, solar radiation pressure. SEPSPOT is further constrained by its solution method, which may require a very good guess to yield a converged optimal solution. Here the authors have developed an approach using collocation intended to provide solution times comparable to those given by SEPSPOT while allowing for greater robustness and extensible force models

Analysis for biotechnology innovations using Strategic Environmental Assessment (SEA):

" Meeting the food needs of the world's growing population while reducing poverty and protecting the environment is a major global challenge. Genetically modified crops appear to provide a promising option to deal with this challenge. However there is a need to make strategic decisions on how to spend limited agricultural research funds in order to achieve a maximum impact with regard to finding sustainable solutions to end hunger and poverty. In international development institutions, there is growing interest in the potential use of Strategic Environmental Assessment (SEA) as part of a research based Environmental Management System (EMS) to promote mainstreaming of environmental considerations in policy development. SEA was developed as an approach to integrate environmental considerations at a policy level, where alternatives environmental policies can be evaluated. In this paper, we propose using SEA in a policy research and priority setting process regarding new technologies, taking the development of Genetically Modified Organisms (GMOs) as an example. We propose that this method would be a useful tool for the international agricultural research centers of the Consultative Group for International Agricultural Research (CGIAR), streamlining business processes, strengthening accountability, sharpening the research agenda it supports, fostering broader partnerships, and increasing the relevance and impact of CGIAR research in achieving international development goals. Currently international law requires only Environmental Impact Assessments (EIAs) of specific biotechnology projects. The incorporation of environmental considerations only at the level of specific projects precludes the adoption of alternative environmental policies. In this review, we outline an SEA approach currently being considered at the International Food Policy Research Institute (IFPRI) for use in evaluating biotechnology policies. SEA may be a useful tool to inform the evaluation of biotechnology policies and priorities by taking account of information on the economic, social, and environmental benefits, cost and risks of adopting those policies."

Security analysis for agroterrorism: applying the threat, vulnerability, consequence framework to developing countries

"We examine access to, use of, and participation in decisions on improved water supply in the Volta basin of Ghana, one of the first countries to introduce a community-based approach to rural water supply on a large scale. While 71 percent of the households interviewed have access to improved water, 43 percent of these continue to use unsafe sources as their main domestic water source. Our results indicate that quality perceptions and opportunity costs play an important role in households' choice of water source. The effect of prices and income levels on this choice differs according to the pricing system used. Given that supply characteristics such as the location and pricing system affect household decisions to use the improved source, households may try to influence these characteristics in their favor during the community decision-making process for the improved source. However, less than 40 percent of the households interviewed participated in decisions on location or technology. We argue that the decision whether to participate depends on three main factors: (i) the household's bargaining power, (ii) the potential benefits from influencing outcomes, and (iii) the cost of participation, (mainly opportunity cost of time). Our results indicate that bargaining power matters In some developing countries the potential exists for agroterrorism to cause widespread disruption through loss of sustenance, income and production. Defense of agriculture may also be problematic because of the lack stability and basic biosecurity infrastructure for the detection and prevention of diseases or invasive species. Currently new methodological approaches for terrorism risk assessments are being actively explored for resource prioritization. One such methodology for risk based allocation of resources is Threat, Vulnerability, and Consequence (TVC) Analysis. A qualitative application of the TVC framework is used to analyze the risk of agroterrorism in developing countries relative to industrialized countries. The analysis suggests that evidence exists to demonstrate general terrorist threats, vulnerability of agriculture and, depending on the country, potentially serious consequences arising from argoterrorism. Where specific threats emerge, action may be needed by the international community to strengthen biosecurity systems in developing countries through: increasing global cooperation, capacity building in monitoring, remediation and risk analysis technologies, and the dissemination of novel technologies for control of pests and diseases."

Hydrodynamic interaction in quasi-two-dimensional suspensions

Confinement between two parallel surfaces is found, theoretically and experimentally, to drastically affect the hydrodynamic interaction between colloid particles, changing the sign of the coupling, its decay with distance and its concentration dependence. In particular, we show that three-body effects do not modify the coupling at large distances as would be expected from hydrodynamic screening.Comment: 8 pages, 2 figure

Spatial patterns of the temporal dynamics of three gadoid species along the Norwegian Skagerrak coast

Journal home page: http://www.int-res.com/journals/meps/Time series from an extensive research survey of juveniles of cod Gadus morhua, pollack Pollachius pollachius and whiting Merlangius merlangus sampled from 1919 to 1994 at 38 stations along the Norwegian Skagerrak coast were investigated. Spatial and temporal analyses were performed to study the spatial pattern of the temporal dynamics of the 3 fish species. Spatially consistent variations were detected in abundance, year-to-year fluctuation as well as in periodicity. The spatial heterogeneity occurred at a mesoscale (differences between fjords) and at a local scale (differences between stations within a fjord) for the 3 gadoids. However, the magnitude of the spatial heterogeneity differed between species. Cod and whiting, which were more abundant in sheltered areas, showed higher spatial variability than pollack, which was more abundant in exposed locations. In this way, the spatial pattern of abundance appeared to be linked to the scale of variability of the species. All 3 species exhibit periodic fluctuations of 2 to 2.5 yr in their optimal habitats, which probably resulted from intrinsic interactions in age-structured populations, such as density-dependent competition and cannibalism. In addition, all the species exhibited long-term trends possibly due to extrinsic forces, such as environmental changes or anthropogenic influences
