Developing geographic information infrastructures: the role of access policies

Within societies, information availability is a key issue affecting society's well‐being. For geographic information, a geographic information infrastructure (GII) facilitates availability and access to geographic information for all levels of government, the commercial sector, the non‐profit sector, academia, and ordinary citizens. Although the importance of access policies in the development of a GII is commonly understood, research that has assessed the impact of access policies on this development is scant. This article adds this perspective. Based on information acquired from case‐study and literature research, the author argues that open‐access policies do not always promote GII development and in specific instances are counter‐productive. These findings may explain why many nations still adhere to cost‐recovery policies instead of following access policies recommended by research. The article provides alternatives for changing current policies into new access policies that promote GII development.

More than just access to fish: The pros and cons of fisher participation in a customary marine tenure (Padu) system under pressure

The Padu system of South Asia has received growing attention as an example of customary marine tenure that has survived despite rapid development and change throughout the region’s fisheries. This paper describes the Padu system as it functions at Pulicat lagoon, India, where it has enjoyed decades of legitimacy amongst its members, and has contributed to sustainable fishing. Recently, however, the Padu system has become unstable, driven by pressures of an expanding fishing population, reduced access to fishing grounds and a growing ‘shared poverty’. In spite of this, fisher loyalty to uphold the Padu system remains strong. This raises questions about the broader social, political and cultural meanings of Padu, which extend beyond access to a lucrative fishery. The paper highlights a trade-off between the benefits received through Padu membership at a societal level through collective action, and the individual costs of partaking in ‘shared poverty’, which is inherently distributed unequally amongst fishing families. The paper concludes with a discussion on the future of the Padu system in Pulicat, drawing from evolutionary pathways of other Padu systems in the region. It is suggested that, in the Pulicat case, the high social values attributed to the Padu system, alongside complex power structures, may hinder institutional adaptation.

Access to land reconsidered: The land grab,polycentric governance and Tanzania’s new wave land reform

Inspired by Ostrom’s concept of polycentric governance, this article aims to refine the analytical framework through which contemporary access to land is analysed. By drawing on extensive fieldwork and conducting a review of the existing literature on the making and implementation of Tanzania’s 1999 land reform, it challenges some of the main assumptions behind the land access and land grabbing literatures about the level at which agency is placed. Processes governing access to land are more contingent than they are most often depicted, involving actors at the local, national and international levels. National and local level actors are often more important than, in particular, the land grab literature tends to suggest. This implies that the state should be seen not merely as a site of ‘legitimate theft’, but also as one in which rights may be upheld. Based on the experience of Tanzania, the article suggests that analytical a priori assumptions about where agency is placed should be abandoned and replaced with empirical research into the relations between actors at all levels.
