    Purpose of the review Resilience is a key concept to deal with an uncertain future in forestry. In recent years, it has received increasing attention from both research and practice. However, a common understanding of what resilience means in a forestry context, and how to operationalise it is lacking. Here, we conducted a systematic review of the recent forest science literature on resilience in the forestry context, synthesising how resilience is defined and assessed. Recent findings Based on a detailed review of 255 studies, we analysed how the concepts of engineering resilience, ecological resilience, and social-ecological resilience are used in forest sciences. A clear majority of the studies applied the concept of engineering resilience, quantifying resilience as the recovery time after a disturbance. The two most used indicators for engineering resilience were basal area increment and vegetation cover, whereas ecological resilience studies frequently focus on vegetation cover and tree density. In contrast, important social-ecological resilience indicators used in the literature are socio-economic diversity and stock of natural resources. In the context of global change, we expected an increase in studies adopting the more holistic social-ecological resilience concept, but this was not the observed trend. Summary Our analysis points to the nestedness of these three resilience concepts, suggesting that they are complementary rather than contradictory. It also means that the variety of resilience approaches does not need to be an obstacle for operationalisation of the concept. We provide guidance for choosing the most suitable resilience concept and indicators based on the management, disturbance and application context

    The aim of this study was to assess associations between the built environment and social environment and excess weight in an urban population. Participants were selected from the Surveillance System for Risk Factors for Chronic Diseases (VIGITEL). The study used data from the city of Belo Horizonte, Minas Gerais State, Brazil. A total of 3,425 interviews from the years 2008 and 2009 were used. Georeferenced data on parks, squares, and locations for physical exercise, population density, and food stores were used to assess the built environment. Description of the social environment used income and homicide rate for the neighborhood. Environmental variables associated independently with excess weight were population density, presence of parks, squares, and locations for physical exercise, and self-reported presence of locations for physical exercise. The findings show that residential neighborhood characteristics are associated with excess weight in urban adults. Os participantes foram selecionados com base no Sistema de VigilĂąncia de Fatores de Risco para Doenças CrĂŽnicas (VIGITEL). O trabalho foi realizado com dados da cidade de Belo Horizonte, Minas Gerais, Brasil. Foram utilizadas 3.425 entrevistas referentes aos anos de 2008 e 2009. InformaçÔes georreferenciadas de parques, praças, lugares para a prĂĄtica de atividade fĂ­sica, densidade populacional e estabelecimentos alimentares foram usadas para avaliar o ambiente construĂ­do. Para caracterizar o ambiente social foi utilizada renda e taxa de homicĂ­dio da vizinhança. As variĂĄveis ambientais associadas independentemente com excesso de peso foram densidade populacional, presença de parques, praças e locais para a prĂĄtica de atividade fĂ­sica e o autorrelato de locais para a prĂĄtica de atividade fĂ­sica. As evidĂȘncias deste estudo mostram que as caracterĂ­sticas das vizinhanças onde as pessoas residem estĂŁo associadas ao excesso de peso de adultos do meio urbano.O objetivo deste estudo foi avaliar as associaçÔes das variĂĄveis do ambiente construĂ­do e social com o excesso de peso em uma população urbana.
