    The wood preservation laboratory of Cirad is accredited by COFRAC (French accreditation committee – accreditation No. 1-1686) for tests on (1) durability of wood and wood-based products; (2) protective efficacy of wood preservatives; (3) efficacy of termite control products. In order to test the efficacy of wood preservatives, non-durable wood blocks are treated using different product doses and exposed to the attack of xylophageous organisms (fungi, insects). To reproduce the ageing of treated wood blocks, some laboratory procedures are available. Amongst them, there is an evaporation procedure, reproducing the action of a warm air flow onto treated wood. This ageing step is very discriminant, as only the formulations fixing effectively the active ingredients will pass the biological test afterwards. This ageing by evaporation is described in the EN73 standard. Nevertheless, many points remain difficult to overcome. The tunnels used for the evaporation are all prototypes; as such equipment is not available currently on the market. So each laboratory has got its own tunnel device. Moreover the way to measure the temperature and speed of the air flow is very difficult to achieve considering the prescriptions of the EN73 standard. The EN73 standard is being revised by the European standardization group (CEN TC38) and despite the metrological aspects were crucial and inadequate in former version, they were not considered as they should. The wood preservation laboratory has forwarded remarks in order to supersede some points of the revision document in order to consider the metrological aspects. This is of main importance as the ageing procedure is commonly used prior to most of the biological test, and such tested products are put on the market based on the efficacy results

    The costs of raising children and the effectiveness of policies to support parenthood in European countries: a Literature Review

    The purpose of this report is to produce an overview of available knowledge about the following issues:  the costs (to parents) of parenthood and of raising children in European Countries;  the effectiveness, in the short and long term, of various policy measures in avoiding or compensating for those costs; 8  the impact of different policy instruments aimed at supporting families according to various policy objectives, e.g. achieving family projects, reconciling family and working life, reducing child poverty, raising the levels of education and well being of children, and increasing equal opportunities.  the wider economic and social costs and benefits of policy interventions in support of families. The current state of knowledge on the following issues is presented as follows in this review report:  The costs of children and the challenges for public policies supporting parenthood (chapter 1); author: O. ThĂ©venon  The policy instruments used in the EU to support families and reduce the costs of parenthood (Chapter 2); authors: A. Math and O. ThĂ©venon  The impacts of these policies on families: o On fertility and the decision to have children (chapter 3); authors M-Th. Letablier and O. ThĂ©venon o On parents‘ participation in the labour market, gender equality and work-life balance (chapter 4); authors: M-Th. Letablier, A. Luci, O. ThĂ©venon o On children‘s well-being (chapter 5): M-Th. Letablier and O. ThĂ©venon  The wider economic and social costs and benefits of such policies (Chapter 6); author: A. Luci. The review of literature presented in this report attempts to make the tools, goals and impacts of family policies more clear and comparable across countries, in order to facilitate the circulation of knowledge between Member States, notably in the context of the European Alliance for Families and the newly established High Level Experts Group on Demography Issues. The report provides a review of recent literature and available data material on the direct and indirect costs of raising children in the European Union (using international as well as particularly important national studies). Ground breaking studies from countries outside the EU, of particular interest from a methodological point of view, are also included in the review. Focus is on the following kinds of costs of having and raising children over the long and short term: - Direct financial costs, e.g. for housing, health care, education, child care, - Indirect financial costs, e.g. for lost income, lost pension rights, lost career prospects etc. , also taking into account the impact on gender roles and gender equality. The costs of raising children are examined at the different phases of their development, from birth through to the age at which they become autonomous. The overview also summarizes knowledge on the main determinants of costs, including, the effects of the number of children, the socio-economic status of parents, and the family structure. Significant differences in cost levels and structures across Member States are identified. The overview also identifies gaps in the available knowledge, and highlights some issues for future research that have the potential to contribute to a better understanding of the policy impact and to better comparability across the European Union.cost of children; family policies; work and family life reconciliation; fertility; female employment
