Abstract The use of recreational ecosystem services is highly dependent on the surrounding environmental and climate conditions. Due to this dependency, future recreational opportunities provided by nature are at risk from climate change. To understand how climate change will impact recreation we need to understand current recreational patterns, but traditional data is limited and low resolution. Fortunately, social media data presents an opportunity to overcome those data limitations and machine learning offers a tool to effectively use that big data. We use data from the social media site Flickr as a proxy for recreational visitation and random forest to model the relationships between social, environmental, and climate factors and recreation for the peak season (summer) in California. We then use the model to project how non-urban recreation will change as the climate changes. Our model shows that current patterns are exacerbated in the future under climate change, with currently popular summer recreation areas becoming more suitable and unpopular summer recreation areas becoming less suitable for recreation. Our model results have land management implications as recreation regions that see high visitation consequently experience impacts to surrounding ecosystems, ecosystem services, and infrastructure. This information can be used to include climate change impacts into land management plans to more effectively provide sustainable nature recreation opportunities for current and future generations. Furthermore, our study demonstrates that crowdsourced data and machine learning offer opportunities to better integrate socio-ecological systems into climate impacts research and more holistically understand climate change impacts to human well-being.

Does the Past Influence the Present or the Future? Deep Time, Land Use, and Remote Sensing in Southern Mexico
This paper reports the initial results of a pilot study investigating the relationships among long-term land use, settlements, historic population, and their potential influence for understanding and evaluating current and future land use. Most of our work to date has been focused on evaluating chang- ing patterns of historic settlement and its relationship to what we know about the historic environment and landscape. Here, we instead rely on remotely-sensed big data as a first step to see how patterns of past land use are correlated with what we know about current land use and land cover. The pilot study initiates a broader research agenda that better incorporates what we know about past landscapes into contemporary land use decisions and to offer critical insights into how the future could be shaped by integrating information about the past. As a first step, the analysis is intentionally broad so that our next steps can provide the fidelity and resolution to offer place based information for design and planning. Nevertheless, it offers a unique window of perception into current land use and a platform for operationalizing evolutionary uses of the past for better managing, designing, and planning complex land systems and moving beyond analogic uses.

The Southeastern United States has high landscape heterogeneity, with heavily managed forestlands, developed agriculture, and multiple metropolitan areas. The spatial pattern of land use is dynamic. Expansion of urban areas convert forested and agricultural land, scrub forests are converted to citrus groves, and some croplands transition to pine plantations. Previous studies have recognized that forest management is the predominant factor in structural and functional changes forests, but little is known about how forest management practices interact with surrounding land uses at the regional scale. The first step in studying the spatial relationships of forest management with surrounding landscapes is to be able to map management practices and describe their proximity to various land uses. There are two major difficulties in generating land use and land management maps at the regional scale by any method: the necessity of large training data sets and expensive computation. The combination of crowdsourced, citizen-science mapping and cloud-based computing may help overcome those difficulties. In this study, OpenStreetMap is incorporated into mapping land use and shows great potential for justifying and monitoring land use at a regional scale. Google Earth Engine enables large-scale spatial analysis and imagery processing by providing a variety of Earth observation datasets and computational resources. By incorporating the OpenStreetMap dataset into Earth observation images to map forest land management practices and determine the distribution of other nearby land uses, we develop a robust regional land-use mapping approach and describe the patterns of how different land uses may affect forest management and vice versa . We find that cropland is more likely to be near ecological forest management patches; few close spatial relationships exist between land uses and preservation forest management, which fulfills the preservation management strategy of sustaining the forests, and production forests have the strongest spatial relationships with croplands. This approach leads to increased understanding of land-use patterns and management practices at local to regional scales.more » « less

null (Ed.)This article explores how scientists adapt to a changing climate. To do this, we bring examples from a case study of salmon habitat restorationists in the Columbia River Basin into conversation with concepts from previous work on change and stability in knowledge infrastructures and scientific practice. In order to adapt, ecological restorationists are increasingly relying on predictive modeling tools, as well as initiating broader changes in the interdisciplinary nature of the field of ecological restoration itself. We explore how the field of ecological restoration is shifting its conceptual gaze from restoring to past, historic baselines to anticipating a no-analog future and consider what this means in terms of understanding the adaptive capacity of knowledge infrastructures and epistemic communities more broadly. We argue that identifying how scientists themselves conceptualize drivers of change and respond to these changes is an important step in understanding what adaptive capacity in science might entail. We offer these examples as a provocation for thinking about “adaptive epistemologies” and how adaptation by scientists themselves can facilitate or hinder particular environmental or sociotechnical futures.more » « less

In this paper, we examine private-sector collection and use of metadata and telemetry information and provide three main contributions: First, we lay out the extent to which “non-content”—the hidden parts of Internet communications (aspects the user does not explicitly enter) and telemetry—are highly revelatory of personal behavior. We show that, privacy policies notwithstanding, users rarely know that the metadata and telemetry information is being collected and almost never know the uses to which it is being put. Second, we show that consumers, even if they knew the uses to which this type of personal information were being put, lack effective means to control the use of this type of data. The standard tool of notice-and-choice has well known problems, including the user’s lack of information with which to make a choice; and then, even if the user had sufficient information, doing so is not practical.49 These are greatly exacerbated by the nature of the interchanges for communications metadata and telemetry information. Each new transmission—each click on an internal link on a webpage, for example—may carry different implications for a user in terms of privacy. The current regimen, notice-and-choice, presents a completely unworkable set of requests for a user, who could well be responding many times a minute regarding whether to allow the use of metadata beyond the purposes of content delivery and display. This is especially the case for telemetry, where the ability to understand both present and future use of the data provided from the sensors requires a deeper understanding of what information these devices can provide than anyone but a trained engineer would know. Third, while there has been academic and industry research on telemetry’s use, there has been little exploration of the policy and legal implications stemming from that use. We provide this factor, while at the same time addressing the closely related issues raised by industry’s use of communications metadata to track user interests and behaviormore » « less
