The value of virtual conferencing for ecology and conservation

The objectives of conservation science and dissemination of its research create a paradox: Conservation is about preserving the environment, yet scientists spread this message at conferences with heavy carbon footprints. Ecology and conservation science depend on global knowledge exchange—getting the best science to the places it is most needed. However, conference attendance from developed countries typically outweighs that from developing countries that are biodiversity and conservation hotspots. If any branch of science should be trying to maximize participation while minimizing carbon emissions, it is conservation. Virtual conferencing is common in other disciplines, such as education and humanities, but it is surprisingly underused in ecology and conservation. Adopting virtual conferencing entails a number of challenges, including logistics and unified acceptance, which we argue can be overcome through planning and technology. We examined 4 conference models: a pure‐virtual model and 3 hybrid hub‐and‐node models, where hubs stream content to local nodes. These models collectively aim to mitigate the logistical and administrative challenges of global knowledge transfer. Embracing virtual conferencing addresses 2 essential prerequisites of modern conferences: lowering carbon emissions and increasing accessibility for remote, time‐ and resource‐poor researchers, particularly those from developing countries.     

Still falling short: protection and partnerships in the Lebanon emergency response

The Israeli–Hezbollah conflict in the summer of 2006, although brief, had a lasting impact on the region and prompted an intense humanitarian response. The conflict raised challenging questions for the United Nations (UN) about how to assist a middle‐income yet extremely vulnerable population in a context where global and local relations are highly politicised. This paper focuses on two key questions that emerged from the humanitarian response. First, how can humanitarian agencies, and particularly the UN, improve the protection of civilians, and was what they did in Lebanon enough? Second, how can humanitarian agencies create partnerships with local actors and still remain true to core humanitarian principles when local actors are fiercely divided along confessional lines and influenced by external actors, and when some, such as Hezbollah, are parties to the conflict? This paper argues that despite the importance of protection and partnerships to the humanitarian response, their role in the UN emergency response still falls short.     

Optimal Reorganization of NASA Earth Science Data for Enhanced Accessibility and Usability for the Hydrology Community

A long‐standing “Digital Divide” in data representation exists between the preferred way of data access by the hydrology community and the common way of data archival by earth science data centers. Typically, in hydrology, earth surface features are expressed as discrete spatial objects (e.g., watersheds), and time‐varying data are contained in associated time series. Data in earth science archives, although stored as discrete values (of satellite swath pixels or geographical grids), represent continuous spatial fields, one file per time step. This Divide has been an obstacle, specifically, between the Consortium of Universities for the Advancement of Hydrologic Science, Inc. and NASA earth science data systems. In essence, the way data are archived is conceptually orthogonal to the desired method of access. Our recent work has shown an optimal method of bridging the Divide, by enabling operational access to long‐time series (e.g., 36 years of hourly data) of selected NASA datasets. These time series, which we have termed “data rods,” are pre‐generated or generated on‐the‐fly. This optimal solution was arrived at after extensive investigations of various approaches, including one based on “data curtains.” The on‐the‐fly generation of data rods uses “data cubes,” NASA Giovanni, and parallel processing. The optimal reorganization of NASA earth science data has significantly enhanced the access to and use of the data for the hydrology user community.

Drought,water access,and urban agriculture: a case study from Silicon Valley

In California, the growing popularity of urban agriculture (UA) has unfolded against a backdrop of historic drought. While UA is often celebrated as an urban sustainability strategy, it must be able to persist during drought if it is to perform these functions. Using Santa Clara County – the geographic core of Silicon Valley – as a case study, we use interviews and surveys to explore the implications of drought for UA. We show how developing an understanding of water access for UA during a drought requires examining the social and institutional context of water management and use. In metropolitan California, the highly decentralised water supply system combined with the diverse institutional arrangements that support UA create an uneven landscape of water access. Consequently, the pressure to change water-consuming practices – that is, the stress that institutional drought responses place on different water users – is geographically and socially differentiated. Among UA water users, responses to drought have also varied, in part because the possibilities for change are constrained by the sociotechnical arrangements of UA sites and the different purposes of UA.     

Walking in the Irish countryside: landowner preferences and attitudes to improved public access provision

This paper explores the attitudes of landowners across Ireland to the wider provision of public access for recreational walking using a multinomial logit model. The study also investigates the level of compensation required to improve the supply of this public good. Results indicate that 51% of landowners are not willing to provide access (non-providers), 21% are willing to provide access free of charge (free providers) and 28% seek compensation (willing providers). The findings indicate that participation by landowners in a proposed public access scheme is influenced by landowners' experience with walkers, farm type, farm insurance costs, household demographics, regional variations, opportunity cost of land and participation in other agri-environment schemes. Mean willingness-to-accept for landowners willing to facilitate improved public access for walking was found to be €0.27 per metre of walkway.     

A factor analytic study of attitudinal structure and its impact on rural landowners' access policies

Previous research has shown that rural landowners' hunter access policies are determined in large part by their attitudes towards hunters, legal liability, conservation, and economic incentives. The results of this study support this research and indicate that East Texas, USA, landowners' decisions to allow or restrict access are based, in part, on attitudes toward hunter behavior, hunting as a social activity, leasing as a management practice, and a perceived obligation toward wildlife stewardship. Attitude-based profiles of landowners who adopted one of four access policies are compared.     

RIVER RECREATION: PUBLIC ACCESS VS. RIPARIAN RIGHTS1

ABSTRACT: The issues involved in the conflict between the rights of the public and those of riparian landowners are examined by reviewing the public access situation with regard to inland streams in the State of Virginia. Consideration is given to the legal framework defining access rights and to the attitudes of riparian landowners regarding the access question. Existing provisions of law suggest only limited recognition of public rights, but this law is incompletely developed. A considerably broader concept of public rights could be developed within the existing framework due to the existence of unresolved questions. The analysis of landowner attitudes is based on a survey of a sample of riparian owners chosen from throughout the state. The questionnaire used in the survey contained 123 questions in a variety of areas, including landowners' perceptions of public rights, problems encountered as the result of recreational water use, attitudes toward state designation and protection of scenic rivers, and the acceptability of alternatives for increasing public access. Although the survey results indicate substantial acceptance of the concept of public use, the landowners expressed concern over governmental control of land use and did not indicate a generally acceptable means for increasing public use.     

Tribal communities,the forests,the fisher folk and the river: whither water justice?

Excessive exploitation of and skewed access to dwindling water resources raise serious water justice concerns. Environmental justice movements and related literature have raised critical questions regarding the unequal distribution of the costs and benefits of a development paradigm that is founded on excessive exploitation and appropriation of natural resources. This paper explores the growing relevance of a water justice framework that addresses both the social and ecological aspects of water use and appropriation, with reference to a four-decade long water conflict over the Chaliyar River in Kerala, South India. It highlights how ecosystem degradation and denial of justice go hand in hand. The paper argues that the framing and articulation of the conflict in a partisan manner led to the glossing over of certain critical features, thus preventing a full view of water injustices. It also failed to inform subsequent policies and practices in this regard.     

Groundwater resources in India: an arena for diverse competition

There is evidence of a looming groundwater crisis in India. Unlike in the case of surface water, competition around groundwater generally does not result in open conflicts. Measurability and visibility of surface water accord a clearer public perception of water quantities, which leads to conflicts. Groundwater in an aquifer is sourced in a dispersed manner, and boundaries, quantities and interdependencies are less visible or measurable. Hence, groundwater resources go through intense and intricate competition between users and uses before open conflicts begin. Competition occurs with reference to sources rather than around the resource. The interdependency of sources is a function of changing patterns of usage as intricacies of aquifer characteristics come into play. Governance institutions and regulatory frameworks of groundwater need to be sensitive to the various forms in which groundwater competition manifests in different hydrogeological settings, and the consequences of this in terms of access and rights, in relation to issues of equity and justice.
