RESUMEN
It is widely understood that nature engagement benefits human wellbeing. Such benefits have been found for real as well as virtual engagements. However, little is known about the role of nature-based videos in social media on wellbeing. With COVID-19 restrictions limiting people's direct engagement with natural environments, this study critically examined people's reactions to nature videos posted on Facebook during the first UK COVID-19 lockdown in 2020. Data consisted of comments on videos containing highlights from the British Broadcasting Corporation's (BBC) Springwatch 2020 television series, and from a UK television presenter and naturalist's (Chris Packham) livestream videos, posted on Facebook from March to July, 2020. Looking at the quantitative profile of a range of videos (i.e. views, likes and shares) and a detailed analysis of the 143,265 comments using thematic analysis, three major themes were generated as: (1) engaging with nature via social media is emotionally complicated, (2) cognitive and reflective reactions are generated from social media nature engagement and (3) engagement with nature-based social media as a mechanism for coping with stress during COVID-19. These findings inform understanding of how nature-related social media content and associated commentary have supported wellbeing throughout the ongoing pandemic and their importance as a means of continued support for wellbeing. 'We feel that the injection of wildlife into people's homes, particularly at this point, would be really valuable and uplifting'. - Chris Packham, 2020.
RESUMEN
Field size distributions and their changes have not been studied over large areas as field size change datasets are not available. This study quantifies agricultural field size changes in a consistent manner using Landsat satellite data that also provide geographic context for the observed decadal scale changes. Growing season cloud-free Landsat 30 m resolution images acquired from 9 to 25 years apart were used to extract field object classifications at seven sites located by examination of a global agricultural yield map, agricultural production statistics, literature review, and analysis of the imagery in the US Landsat archive. High spatial resolution data were used to illustrate issues identifying small fields that are not reliably discernible at 30 m Landsat resolution. The predominant driver of field size change was attributed by literature review. Significant field size changes were driven by different factors, including technological advancements (Argentina and USA), government land use and agricultural policies (Malaysia, Brazil, France), and political changes (Albania and Zimbabwe). While observed local field size changes were complex, the reported results suggest that median field sizes are increasing due to technological advancements and changes to government policy, but may decrease where abrupt political changes affect the agricultural sector and where pastures are converted to arable land uses. In the limited sample considered, median field sizes increased from 45% (France) to 159% (Argentina) and decreased from 47% (Brazil) to 86% (Albania). These changes imply significant impacts on landscape spatial configuration and land use diversity with ecological and biogeochemical consequences.
