TL;DR: In this article, the authors provide a state-of-the-art examination of the rapidly advancing field of extension science, emphasizing a number of subjects, most importantly the concept of the agricultural information system in which agricultural research extension workers and farmers are linked.

TL;DR: The UK Government's Foresight Global Food and Farming Futures project as mentioned in this paper aims to improve dialogue and understanding between agricultural research and policy by identifying the 100 most important questions for global agriculture.

TL;DR: In this article, a review of the evolution of extension science from its beginnings to where it is heading now is presented, starting from its original question (how do I get them where I want them?) and its sequel (why don't they do what I want to do), the article follows the sequence of extension sciences emphases: resistance to change, innovation diffusion, target categories, countervailing utili-ser systems and, presently, knowledge systems which see extension, research and utilisers as a synergetic whole.

TL;DR: In this paper, the authors construct a framework for sustainable agriculture, comprising technology, farmer activity, ecosystem level, extension, diffusion, policy, knowledge system and epistemology, and conclude that the ecological imperative gives rise to a paradigm shift in policy with far-reaching practical consequences.
