“…Native ecosystems commonly remain or have been rehabilitated within and around Australian cities (Newton et al 2001;Bekessy et al 2012), and while many fauna species have declined or become extinct within these areas (Piper and Catterall 2003;Catterall 2009), many populations of native forest birds, mammals and plants still persist (Brady et al 2011;Moxham and Turner 2011;Shanahan et al 2011a, b;Daniels and Kirkpatrick 2012;Stagoll et al 2012). Thus, tree cover and remnant vegetation cover provide measures respectively of the greenness and the ecological value of parks.…”

Public parks commonly contain important habitat for urban biodiversity, and they also provide recreation opportunities for urban residents. However, the extent to which dual outcomes for recreation and conservation can be achieved in the same spaces remains unclear. We examine whether greater levels of (i) tree cover (i.e. park 'greenness') and (ii) native remnant vegetation cover (i.e. vegetation with high ecological value) attract or deter park visitors. This study is based on the park visitation behaviour of 670 survey respondents in Brisbane, Australia, detailing 1,090 individual visits to 324 urban parks. We first examined the presence of any clear revealed preferences for visiting parks with higher or lower levels of tree cover or remnant vegetation cover. We then examined the differences between each park visited by respondents and the park closest to their home, and used linear mixed models to identify socio-demographic groups who are more likely to travel further to visit parks with greater tree cover or remnant vegetation cover. Park visitation rates reflected the availability of parks, suggesting that people do not preferentially visit parks with greater vegetation cover despite the potential for improved nature-based experiences and greater wellbeing benefits. However, we discovered that people with a greater orientation towards nature (measured using the nature relatedness scale) tend to travel further for more vegetated parks. Our results suggest that to enhance recreational benefits from ecologically valuable spaces a range of social or educational interventions are required to enhance people's connection to nature.

“…En este ámbito donde la periurbanización, acompañada de modificaciones en la fisiografía de su territorio en diferentes escalas espaciales y temporales ha sido un fenómeno secular, la relación entre el territorio y las respuestas que durante el tiempo cada sociedad ha dado ante su crecimiento y las variaciones naturales del ambiente (Bekessy et al, 2012;Schteingart, 1987) ayudan a explicar los procesos de urbanización y sus impactos ambientales. Sin embargo, en Villahermosa existen pocos análisis sobre el estado actual y tendencias de cambio de los usos del suelo por urbanización, a pesar de ser información indispensable para sustentar la planificación ambiental dirigida a restablecer servicios y beneficios Pérdida de humedales y vegetación por urbanización en la cuenca del río Grijalva, México ambientales que se traduzcan en bienestar social.…”

“…Estas condiciones de perturbación ambiental y pérdida de biodiversidad han sido frecuentemente relacionadas con la fragmentación de los humedales urbanos y el manejo inadecuado de las aguas de escorrentía y residuales (Bekessy et al, 2012;Henny y Meutia, 2014;Hettiarachchi et al, 2014), sobre todo en ciudades, como en Villahermosa. A ello debe sumarse, la insuficiencia de servicios municipales en zonas marginadas y asentamientos irregulares con la falta de inversión y actualización del sistema de drenaje para controlar las escorrentías y manejo de aguas residuales.…”

“…Las formas que asume la modificación de los ecosistemas por el medio construido, depende de las características físicas y sociales de los espacios circundantes, el ritmo de la expansión urbana, las formas de producción, y el contexto sociopolítico en que suceden estos procesos (Schteingart, 1987). En este sentido, sus consecuencias son especialmente notables en las zonas marginadas de bajo precio y sin servicios municipales, en poblados dedicados a la economía de subsistencia y en ecosistemas conservados y mínimamente habitados ubicadas en la periferia de las ciudades (Bekessy et al, 2012;Carranza y Ruiz, 2012).…”

The sea-breeze (SB) is an important source of summertime precipitation in North Carolina (NC, southeast United States). However, not all SB events produce precipitation. A climatology of wet and dry SB events in NC is used to investigate the conditions that are conducive to precipitation associated with the sea breeze.Radar imagery was used to detect 88 SB events that occurred along the NC coast between MaySeptember of 2009-2012. The majority (85%) of SB events occurred during offshore flow (53%) or during flow that was parallel to the coast (22%). SB events were separated into dry (53%) and wet (47%) events and differences in the dynamic and thermodynamic parameters of the environment in which they formed were analyzed. Significant differences in dynamic and thermodynamic conditions were found. SB dry events occurred under stronger winds (6.00 ± 2.36 ms -1 ) than SB wet events (4.02 ± 2.16 ms -1 ). Moreover, during SB wet events larger values of convective available potential energy and lower values of convective inhibition were present, conditions that favor precipitation. Overall, the SB wet events accounted for 20-30% of the May-September precipitation along the NC coastal region. The position of the North Atlantic Subtropical High (NASH) controls both moisture availability and winds along the NC coast, thus providing a synoptic-scale control mechanism for SB precipitation. In particular, it was shown that when the NASH western ridge is located along the southeast coast of the United States, it causes a moist southwesterly flow along the NC coast that may favor the occurrence of SB wet events.Keywords: Sea breeze; precipitation; North Carolina; North Atlantic Subtropical High; wind direction; wind speed.

Cities are investing billions of dollars in climate change adaptation to combat the effects of sea‐level rise, temperature extremes, increasingly intense storm events, flooding and water scarcity. Natural ecosystems have enormous potential to contribute to city resilience, and so, actions that rely on this approach could sustain considerable co‐benefits for biodiversity. In this paper we identify the prevalence of key themes of human adaptation response that could have biodiversity conservation outcomes in cities. We then quantify the area of impact for actions that identify specific targets for greening or green infrastructure that could involve natural ecosystems, providing an indicator of potential co‐benefits to biodiversity. We then extrapolate to explore the total area of land that could benefit from catchment management approaches, the area of waterways that could benefit from nature‐based improvement of these spaces, and finally the number of threatened species that could benefit across these cities. From 80 city climate adaptation plans analysed, we found that urban greening plays a key role in most adaptation strategies, and represents an enormous opportunity for biodiversity conservation, given the diversity of animal and plant species in urban environments. We show that the ranges of at least 270 threatened species overlap with the area covered by just 58 city adaptation plans, including watershed catchments totalling over 28 million km2. However, an analysis of 80 city adaptation plans (of a total 151 found globally) shows that this opportunity is being missed. Just 18% of the plans assessed contained specific intentions to promote biodiversity. We highlight this missed opportunity, as climate adaptation actions undertaken by cities represent an enormous incipient opportunity for nature conservation. Finally, we encourage planners and city governments to incorporate biological conservation into climate adaption plans, for the mutual benefit of urban societies and their biodiversity.
