Nowadays, children spend less time in direct contact with nature than they did a few decades ago and it is having negative effects on their development and health. There is a growing body of literature showing evidences of these negative effects including physical, psychological and environmental consequences (Ozdemir y Yilmaz, 2008; Wells, 2000). Experiences that imply direct contact with the natural world are essential to people. Not only adults and children prefer to spend time in natural places rather than in urban ones (Castonguay & Juntras, 2009) but they also obtain benefits from the time spent in natural environments. In regard to children, those who have more access to nature show greater self-discipline (Taylor et al., 2002), better cognitive functioning (Wells, 2002) and more adult concern and behavior related to the natural environment (Wells & Lekies, 2006). The present study intends to explore the positive effects that nearby nature has on children, specifically the aim is to search for evidence of how nature increments children´s resilience, and to improve the quality of the urban design. It is known that nearby nature acts as a buffer of the stress produced by daily adversity (Wells & Evans, 2003; Corraliza, Collado & Ferrer, 2008). Children are able to cope with problems better if they have access to nearby nature and therefore their stress level is lower than those who do not have the daily possibility to experience nature. In order to get a better understanding of nature´s buffering effect, the nearby nature of 172 children aged between 10 and 12 was measured by a designed natural scale, as well as the nature they perceive, their frequency of exposure to adversity and psychological distress. Four primary schools were chosen according to the amount of nature present in the school and in its surroundings and the 172 children´s residential areas were visited. Our results support the Buffering Hypothesis showing empirical evidences of higher resilience in children whose access to daily nature is higher. In other words, among children who are exposed to the same frequency of stressful events, those who have daily direct contact with the natural world are able to cope with the stress better and therefore their stress level is lower than children whose daily surroundings are less natural. Furthermore, the protective effects of nearby nature are stronger for the more vulnerable children. The results give us an idea of the profound power of nature as a beneficial factor in children’s health and the importance of taking into account the amount of nearby nature in cities designs.
