Food versus fuel is the dilemma regarding the risk of diverting farmland or crops for biofuel production to the detriment of the food supply. The biofuel and food price debate involves wide-ranging views and is a long-standing, controversial one in the literature. There is disagreement about the significance of the issue, what is causing it, and what can or should be done to remedy the situation. This complexity and uncertainty are due to the large number of impacts and feedback loops that can positively or negatively affect the price system. Moreover, the relative strengths of these positive and negative impacts vary in the short and long terms, and involve delayed effects. The academic side of the debate is also blurred by the use of different economic models and competing forms of statistical analysis. Biofuel production has increased in recent years. Some commodities, like maize (corn), sugar cane or vegetable oil can be used either as food, feed, or to make biofuels. For example, since 2006, a portion of land that was also formerly used to grow food crops in the United States is now used to grow corn for biofuels, and a larger share of corn is destined for ethanol production, reaching approximately 37% in 2023. Oil price increases since 2003, the desire to reduce oil dependency, and the need to reduce greenhouse gas emissions from transportation have together increased gl…

What Should be Done about the History of British Sociology?. This chapter deals with the writing of the history of sociology as an activity in Britain. Work on the history of sociology is not usually approached through the study of its institutions, but this chapter argues that they deserve much more attention than they have received. The British Sociological Association has not been merely a mirror or consequence of what was happening elsewhere; it has also been a motor of change and development which has had consequences for the history (as well as being of interest as an institution in its own right). This chapter reviews some of the ways in which the British Sociological Association has…
