Offshore petroleum and minerals: Plugging gaps in the present framework

For twenty years, it has been realized that there is a gap in New Zealand’s environmental law in that there is no general environmental legislation for the exclusive economic zone, and now for the extended continental shelf that includes areas more than 200 nautical miles offshore. The jurisdiction of regional councils under the Resource Management Act 1991 does not extend beyond the 12-mile limit, about 22 km offshore. (The jurisdiction of territorial authorities extends only to the mean low water mark.) That has meant that oil and gas operations beyond the 12-mile limit have not had proper environmental scrutiny. Public concern about such matters has sharpened in the light of petroleum exploration in the Raukumara Basin off the East Cape, although so far it has only reached the stage of seismic exploration. The Deepwater Horizon blowout on the Macondo prospect in the Gulf of Mexico in April 2010 also looms large in public debate. With a lower profile but with a similar potential to cause environmental harm is the possibility of seabed mining operations. A company is gearing up for deep seabed mining off New Britain in Papua New Guinea. Globally, the main targets are cobalt-rich crusts, polymetallic nodules (on the abyssal plain), and massive sulphide deposits (near hydrothermal vents). In New Zealand iron sands are also attractive. Other possible future uses of the offshore are carbon capture and storage and the extraction of gas hydrates. Existing operations such as fishing by bottom trawling present risks of environmental harm to the benthic environment, especially to features such as seamounts. The Minister for the Environment has now announced his intention to introduce a bill to plug this legal gap, at least in relation to petroleum development and seabed mining. Action on this is most welcome. It is desirable to consider the strengths and weaknesses of the proposal, and of the legal framework for oil and gas well drilling in general. Some surprising gaps remain even if the Minister’s proposal is enacted

Intellectual Property and Biodiversity: When and Where are Property Rights Important?

An important issue in the life sciences industries concerns the nature of the incentive mechanism that should govern the production of innovation within this R&D sector. We look at the specific problem of coordinating the supply of inputs across very different agents - North and South - that must each supply inputs in order to generate innovations from the industry. The current arrangement in this industry provides for a single property right at “end of the pipeline”, i.e. where marketing of the innovation occurs. This property rights scenario raises two problems, one of efficiency and one of equity. The key question asked here pertains to the number and placement of property rights that should be instituted to address this property rights failure. Should one establish new property rights in traditional knowledge alone; property rights in genetic information alone; or in both? We demonstrate that in a world in which traditional knowledge and genetic information are complements in the production of R&D, a resolution of the property rights failure in genetic information also may resolve the allocation failure in traditional knowledge even in the absence of a distinct property right. The reason is that traditional knowledge of the nature of private information is comparable to a trade secret. Traditional knowledge holders may use this informational advantage to improve their benefit by capturing some informational rent. A new property right is important to enable bargaining and coordination to occur across the industry, but a single property right is probably sufficient to enable coordination between the two agents.Biodiversity Prospecting, Traditional Knowledge, Genetic Resources, Intellectual Property Rights, Sequential R&D

A Model of Vertical Oligopolistic Competition

This paper develops a model of successive oligopolies with endogenous market entry, allowing for varying degrees of product differentiation and entry costs in both markets. Our analysis shows that the downstream conditions dominate the overall profitability of the two-tier structure while the upstream conditions mainly affect the distribution of profits. We compare the welfare effects of upstream versus downstream deregulation policies and show that the impact of deregulation may be overvalued when ignoring feedback effects from the other market. Furthermore, we analyze how different forms of vertical restraints influence the endogenous market structure and show when they are welfare enhancing

Voluntary Agreements under Endogenous Legislative Threats

The paper analyzes the welfare properties of voluntary agreements (VA) with polluters, when they are obtained under the legislative threat of an alternative stricter policy option. In the model, the threat is an abatement quota. Both the threat and its probability of implementation are endogenous. The latter is the outcome of a rent-seeking contest between a green and a polluter lobby group influencing the legislature. We show that a welfare-improving VA systematically emerges in equilibrium and that it is more efficient than the pollution quota. We also discuss various VA design aspects.Environmental policy, voluntary agreements, bargaining, legislatures, rent seeking, rent-seeking contests

The prefigurative power of urban political agroecology: rethinking the urbanisms of agroecological transitions for food system transformation

In recent years, urban contexts and urban-rural linkages have become central for scholars and activists engaged in agrarian questions, agroecological transitions and food system transformation. Grassroots experimentations in urban agroecology and farmers' engagement with urban policies have marked the rise of a new agenda aiming to bridge urban and agrarian movements. Departing from the work of Eric Holt-Gimenez and Annie Shattuck, this paper argues that the way urban-rural links have been conceptualized is occasionally progressive, and that an agroecology-informed food system transformation needs radical approaches. Acknowledging that processes of urbanization are dynamic, driven by specific lifestyles, consumption patterns, and value orientations - producing ongoing suburbanization, land enclosures, farmers displacement and food-knowledge loss - the paper argues that thinking transitions through new rural-urban links is unfit to tackle the evolving nature of these geographies, and reproduces the distinction between consumers and producers, living on either side of what Mindi Schneider and Philip McMichael have described as an epistemic and ecological rift. Building on insights from four case-studies across global north and south, the paper reframes agroecological transitions as a paradigmatic change in biopolitical spatial relations, economic values and planning agency - what we call an 'agroecological urbanism'. The paper articulates a transformation agenda addressing urban nutrients, peri-urban landuse, community food pedagogies and farmers' infrastructure

Integrating Herbivore Population Dynamics Into a Global Land Biosphere Model: Plugging Animals Into the Earth System

Mammalian herbivores are an essential component of grassland and savanna ecosystems, and with feedbacks to the climate system. To date, the response and feedbacks of mammalian herbivores to changes in both abiotic and biotic factors are poorly quantified and not adequately represented in the current global land surface modeling framework. In this study, we coupled herbivore population dynamics in a global land model (the Dynamic Land Ecosystem Model, DLEM 3.0) to simulate populations of horses, cattle, sheep, and goats, and their responses to changes in multiple environmental factors at the site level across different continents during 1980–2010. Simulated results show that the model is capable of reproducing observed herbivore population dynamics across all sites for these animal groups. Our simulation results also indicate that during this period, climate extremes led to a maximum mortality of 27% of the total herbivores in Mongolia. Across all sites, herbivores reduced aboveground net primary productivity (ANPP) and heterotrophic respiration (Rh) by 14% and 15%, respectively (p \u3c 0.05). With adequate parameterization, the model can be used for historical assessment and future prediction of mammalian herbivore populations and their relevant impacts on biogeochemical cycles. Our simulation results demonstrate a strong coupling between primary producers and consumers, indicating that inclusion of herbivores into the global land modeling framework is essential to better understand the potentially large effect of herbivores on carbon cycles in grassland and savanna ecosystems

Local Networks to Compete in the Global Era. The Italian SMEs Experience

This study is concerned with the factors that influence the cooperation among cluster-based firms. Theorists have consistently demonstrated the role and importance of economic externalities, such as knowledge spillovers, within industrial clusters. Less attention has been paid to the investigation of social based externalities, though it has been suggested that these may also accrue from geographical agglomeration. This study explores the development of cooperation between firms operating in a single industry sector and in close proximity. The results suggest that social networking has a greater influence than geographic proximity in facilitating inter-firm co-operation. A semi-structured questionnaire has been developed and the answers were analysed with a stepwise regression model.Networks, Inter-Firm Cooperation, SMEs
