To call a scholarly volume a handbook conveys a promise ofthe authority, completeness and balance that readers expectfrom a reference work. The editors of the Handbook onAgriculture, Biotechnology and Development have taken onan especially challenging task by attempting to compile areference book on such a politically contentious topic. Sincethe emergence of recombinant DNA techniques in the late1970s,theiruseinagriculturalcropimprovementhascometoappear much more complicated than hoped for or expected.Stabilisinganewgenetictraitinacultivarhasturnedouttobethe easy step. Stabilising the new cultivar within a complexwebofsocial,technical,economicandecologicallinkageshasproved to be something much more difficult to accomplish.Assessing the impact of a new technology on agricultureand fathoming the responses of societal interest groups andstakeholders are equally demanding. Succinctness is not anoption. This book extends to almost 870 pages, including ausefulindex,andcomprisesnofewerthan51chapterswrittenby nearly 90 distinguished contributors. The individual chap-ters are generally concise, coherent and packed with informa-tion, many of them providing the kind of topical overviewsone would expect of a handbook. Does the book as a wholeachieve the same clarity and coherence?Let us first look at what has been done to order the terrain.The editors haveadopted a formalframework based on‘threeinterrelated, three-pronged approaches to assessing the rela-tionships between agriculture, biotechnology and develop-ment’ (p.2). The first and third approaches are fairly clearand straightforward, inviting authors to distinguish betweenaccepted science, current research, and ‘speculative pursuits’(pp.2–3) and to be explicit about the models, methods andmetricstheyused.Sofar,somechanical;andtheseproceduralguidelines at least imply that authors were asked to reviewtheir allotted topics fairly broadly.More central and more normative is the second approach,which was to adopt E. Ostrom’s institutional analysis anddevelopment (IAD) framework (Ostrom, 2011)asa‘super-structure’ for the volume (p.3). We find it hard to understandwhy the editors chose this framework, which implicitly de-fines the book’s topic as an abstract institutional,organisational or policy issue. It also implies that publicchoice theory and institutional economics, in which Ostrom’smodel is rooted, are the key tools with which the topic oughtto be approached. This means filtering out some importantpublic, policy and ethical concerns about biotechnology andits interactions with agriculture and development, and demot-ing other disciplinary approaches to a secondary status.The IAD framework shows its value in the chapters whereit is used, but is much less compelling as a justification fordividing the book into three discrete parts, corresponding tothe framework’s three components: exogenous variables, ac-tion arenas and outcomes. For example, the last part of thebook addresses the ‘outcomes’ component, resulting in aninformative set of chapters on the adoption and impacts oftransgenic technologiesinparticularcropsorclassesofcrops.It is in these chapters that the editors’‘models, methods andmetrics’ template makes most sense, and by and large theauthors in this section have conscientiously applied it. How-ever, this means that each chapter devotes space to a discus-sion of the types of econometric models and methods avail-able to assess the impacts of transgenic crops, those thathappen to have been used by scholars assessing the particularcrop or crops under discussion in that chapter, the character-istics, strengths and limitations of these methods, and techni-cal questions about how to handle particular issues arisingfrom the types of transgenic traits under consideration.
