L'analyse de données joue un rôle croissant dans la recherche agronomique, l'expertise scientifique et les études prospectives. Des sources de données multiples sont souvent disponibles pour estimer un paramètre clé ou pour tester une hypothèse d'intérêt scientifique ou sociétal. Ces données, obtenues dans différentes conditions environnementales ou basées sur différents protocoles expérimentaux, sont généralement hétérogènes. Parfois même, elles ne sont pas accessibles et il est nécessaire de les extraire d'articles scientifiques ou de rapports. Pourtant, une analyse globale des données disponibles est essentielle pour augmenter la précision des estimations, évaluer la robustesse des conclusions et comprendre l'origine de la variabilité de certains résultats. Une synthèse quantitative de l'ensemble des données disponibles permet de mieux comprendre les effets de facteurs expérimentaux et d'affiner les recommandations agronomiques. Conçu comme un guide méthodologique, cet ouvrage montre les intérêts et les limites de différentes méthodes statistiques permettant d'analyser des données issues de réseaux expérimentaux et de réaliser des méta-analyses. Il s'adresse aux ingénieurs, étudiants et chercheurs impliqués dans l'analyse de données agronomiques. Notre objectif est de présenter les principales méthodes statistiques permettant de réaliser une synthèse quantitative des données issues des réseaux expérimentaux et des publications scientifiques. Chaque chapitre expose une ou plusieurs méthodes et les illustre à l'aide d'exemples traités avec le logiciel R. Les données et les codes R sont fournis et commentés afin de faciliter leur adaptation à d'autres situations pratiques. Ils peuvent être utilisés à partir du « package » R KenSyn associé à ce livre.

This paper presents an overview and meta-analysis of the effects of water, sanitation, and hygiene interventions around the world. It is based on 136 impact evaluations (randomized and quasi-experimental studies) that explore the effects of water, sanitation, and hygiene interventions on health and non-health outcomes, ranging from behavior change-such as the adoption of water treatment-to school attendance rates, to a reduction in diarrhea. The selected impact evaluations were divided into five groups, and meta-regressions with fixed effects (at the regional level) and random effects were performed, controlling for each study's characteristics (implementing organization, sample sizes, type of publication, number of publication views, and so forth). All results are reported as changes in odds ratios, with respect to the standard deviation of reported effects. Water, sanitation, and hygiene interventions were found to increase the likelihood of behavior changes and the adoption of new hygiene practices by 17 percent. The smallest effects were observed from water, sanitation, and hygiene interventions aimed at reducing the rates of child mortality and non-diarrheal disease. Water, sanitation, and hygiene interventions implemented in schools showed statistically significant results in reducing school absenteeism and dropouts. Similarly, the results showed a statistically significant aggregate likelihood of increased access to safe water and improved water quality, as well as increased water treatment options-a difference of one-fifth with respect to the standard deviation of the average effect size reported. Finally, the results showed that water, sanitation, and hygiene interventions reduced the likelihood of the incidence of diarrheal and enteric disease by 13 percent, which is consistent with findings in other meta-analyses of the same subject.

Transport corridors can generate wider economic benefits and costs through their effects on a potentially diverse set of development outcomes, such as economic growth, poverty, jobs, equity, environmental quality, and economic resilience. To advance understanding of how corridors could generate wider economic benefits, this paper undertakes a quantitative review of the literature that estimates the economic benefits of large transport infrastructure projects. It conducts a meta-analysis of 234 estimated impacts found in 78 studies. It focuses on roads, rails, and waterways because transport corridors based on these modes have clearer potential for economic spillovers than, for example, airline routes. The conceptual structure for the review is guided by a simple canonical model describing the policy maker's problem in maximizing the net wider economic benefits of corridors. The meta-analysis confirms that characteristics of individual studies, as well as the placement and design of the transport infrastructures systematically influence the findings of the corridor studies. It also shows that, on average, estimated impacts of corridor interventions on economic welfare and equity tend to be beneficial, while they are often detrimental for environmental quality, and possibly also for social inclusion. Because, around this average, impacts vary widely, policy makers could use complementary policies and institutions to mitigate potential trade-offs and support losers. To clarify the nature and extent of these trade-offs and varied impacts across locales and population groups, much more research is required.

How society's undervaluing of life puts all of us at risk-and the groundbreaking economic measure that can fix itLike it or not, sometimes we need to put a monetary value on people's lives. In the past, government agencies used the financial "cost of death" to monetize the mortality risks of regulatory policies, but this method vastly undervalued life. Pricing Lives tells the story of how the government came to adopt an altogether different approach--the value of a statistical life, or VSL-and persuasively shows how its more widespread use could create a safer and more equitable society for everyone.In the 1980s, W. Kip Viscusi used the method to demonstrate that the benefits of requiring businesses to label hazardous chemicals immensely outweighed the costs. VSL is the risk-reward trade-off that people make about their health when considering risky job choices. With it, Viscusi calculated how much more money workers would demand to take on hazardous jobs, boosting calculated benefits by an order of magnitude. His current estimate of the value of a statistical life is
