INTRODUCTION: Insecticide-treated mosquito nets (ITNs) are highly effective for the control of malaria. Yet widely distributed ITNs have been repurposed as fishing nets throughout the world. OBJECTIVES: Herein we present a synthesis of the current knowledge of ITN fishing and the toxicity of pyrethroids and discuss the potential implications of widespread fishing with ITNs. We further review effective management strategies in tropical fisheries to explore a framework for managing potential ITN fishing impacts. DISCUSSION: Pyrethroids are toxic to fish and aquatic environments, and fishing with ITNs may endanger the health of fisheries. Furthermore, although human toxicity to the pyrethroid insecticides that impregnate ITNs is traditionally thought to be low, recent scientific advances have shown that pyrethroid exposure is associated with a host of human health issues, including neurocognitive developmental disorders, diabetes, and cardiovascular disease. Although it is known that ITN fishing is widespread, the implications for both fisheries and human communities is understudied and may be severe.
Anaerobic digestion (AD) on farms is receiving increasing attention as a technology for minimizing greenhouse gas emissions, reducing odors and pathogens, and generating energy. Although AD technology in the U.S. has been considered appropriate only for larger scale, especially livestock, farms, there has been growing interest in adapting the technology for smaller farms and greater variety of feedstocks. A series of three workshops used farmer-participatory research methodologies to assess attitudes and perceptions of small-scale anaerobic digesters in New York State by smaller scale livestock and crop operations. Results indicate a diverse group of farmers are interested in using anaerobic digester systems. Participants who attended the tour and workshop also increased their level of knowledge and understanding of anaerobic digester systems. Participant discussion revealed a need for more information for AD establishment on small farms including detailed economic data and a greater number of example AD systems. Additionally, results showed improved funding sources for adoption of this sustainable technology will likely increase farmer's rate of adoption.
Beginning in 1980, and due to a number of significant court decisions, legislative initiatives and international economic agreements, there has been an increase in the importance and use of intellectual property mechanisms, such as patents, in protecting biological materials, including seeds and engineered crop traits. The trend originated in the U.S. but has since diffused to OECD and non-OECD nations. A parallel but related set of policies designed to promote the patenting of university and federally funded research discoveries has also become evident in the U.S. and globally. In this paper, we discuss the trend toward more restrictive IP protections in agriculture through national-level policies and international economic agreements especially for new plant varieties. We then present the case of plant science research in Taiwan, including interviews with 15 plant scientists, to illustrate how transnational trends can impact and interact with national level policies and practices. And, how research scientists can play critical roles in furthering or retarding the progression of the proprietary research model in plant science.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
