The adoption of agricultural technologies, whether developed through biotechnology or other methods, depends on social, political, regulatory and biological parameters. This article first presents an example of a low-input, non-biotechnological method of pest control that, while seemingly reasonable to researchers and extension agents, was not adopted by farmers. It then analyses a method for insect management developed through biotechnology that is becoming widely adopted: transgenic plants expressing insecticidal proteins from the bacterium Bacillus thuringiensis (Bt). Globally increasing adoption of Bt plants, by small and large farmers in both low- and high- income countries requires explanation in terms of biological properties of cropping systems and insect populations, alternative control techniques and social policy considerations. 相似文献

Anthony Downs 《Housing Policy Debate》2013,23(2):439-463
Abstract This paper assesses the major forms of federal housing assistance and compares the relative value of each in meeting the housing needs of the nation's low‐ and moderate‐income households. Programs are first identified and described. A ranking system, based on nine criteria of desirability, is then developed and used to compare the programs. The evaluation system presented in this paper represents one method of determining how to allocate scarce federal housing assistance funds. The subjective nature of the evaluation process dictates that other criteria and weighting systems may be legitimately applied. However, to provide a clear decision‐making framework, any such system should clearly explain its assumptions and rationales. 相似文献

Myanmar’s Rohingya conflict is arguably the most sensitive and complex issue facing the country, both in terms of the extent of physical and social destruction, and the impact on Myanmar’s domestic reform and international standing. The scale of human suffering is mind-numbing, the reactions of Aung San Suu Kyi and the Myanmar authorities baffling. However, too much international commentary is reductionist, flattening multiparty and multifaceted sociopolitical dynamics into a simple narrative, which is detrimental to understanding and responding to the conflict. This paper attempts to make sense of some of this complexity, firstly by addressing several common misperceptions of the conflict, then analysing it from a variety of theoretical perspectives. The first misconception is that this conflict is not new, but significant antecedents date back at to at least World War II, if not before. The second is that this conflict is not merely about state oppression of a despised and vulnerable ethno-religious minority, but rather a multipolar conflict with conflict and violence, driven by mutual existential fears and deeply historical grievances on all sides, by at least three key actors. This multipolarity needs to be better understood but outsiders seeking resolution of the conflict. And finally, the third is that this conflict is not primarily about the denial of citizenship and statelessness of the Muslims, as significant as this is, but about definition of the political community in Myanmar and the politics of inclusion/exclusion in governance. Framing this as an ‘intractable conflict’, this paper then examines the drivers of conflict from the perspective of an ethnic security dilemma, a double minority complex, and the political economy, arriving at conclusions about the nature of the conflict and sounding a final warning about a potential moral hazard arising from the way international support is framed and offered. 相似文献
