This chapter is an introduction to economic appraisal. It explains underlying concepts, describes methods used, and discusses the application to public health. Economic appraisal comprises techniques that weigh up the costs of an action, such as providing a public health intervention to an at-risk population group, against the benefits that it provides. Important underlying principles are opportunity cost, social versus private costs and benefits, marginal costs and benefits, efficiency, and equity. There are different types of economic appraisal, each of which measures the costs and benefits of options being compared. Measuring costs involves identifying and describing resource use changes, quantifying them in physical units and valuing them. Issues in cost measurement include use of macro or micro-costing and dealing with inflation and time preference. There are several approaches that can be used to measure benefits depending on the type of economic appraisal being used; a measure of special interest is quality-adjusted life years (QALYs). Modelling is often used in economic appraisal to combine data on the costs and benefits of an intervention. Given the inherent uncertainties involved in economic appraisal it is good practice to undertake sensitivity analyses that investigate the impact of uncertainty. Methodological challenges in undertaking economic appraisals of public health interventions include the importance of equity and inequality considerations, establishing robust evidence of the effect of public health programmes, the relevance of QALYs, and accounting for multisectoral costs and benefits.

AbstractIn Sri Lanka, the agriculture sector is most vulnerable to climate change and this is increasingly affecting food security. Vegetables, legumes, coarse grains, and potatoes are likely to be adversely affected due to climate impacts. Based on a cross-sectional survey conducted on 150 vegetable farmers in the up-country area of Sri Lanka, this study elucidates farmers’ perceptions of climate change, ongoing adaptation methods, factors influencing farmers’ decisions to adapt, and barriers to adaptation. The study finds that gender, educationlevel, farming experience, income, willingness to take credit, extension on crop, climate change information, farmer-to-farmer extension, rainfall and temperature as the significant factors influencing adaptation. Furthermore, early or late planting, crop or variety switching, and intensive use of inputs are the commonly used adaptation options. Information constraints emerge as a major barrier followed by high costs for adaptation and lack of vigorous planting materials. The study suggests educating farmers about potential adaptation options is pivotal.

Abstract There is a large body of research on conflict in nonhuman animal groups that measures the costs and benefits of intergroup conflict, and we suggest that much of this evidence is missing from De Dreu and Gross's interesting article. It is a shame this work has been missed, because it provides evidence for interesting ideas put forward in the article.
