Domestic cookstoves in rural India have long been targeted by development programs dedicated to solving a diverse range of problems from deforestation and indoor air pollution to global warming and rural market inefficiencies. Theories on how technologies are mobilized in these design and diffusion innovation projects and what this presages for development outcomes can be improved by explicitly detailing the composition and structure of program governance frameworks. I develop a ‘dual adoption analytic framework’ to interrogate two technology innovation programs in Western India. This framework underscores the collaborative nature of technology mobilizations and, more specifically, how power is distributed across partnerships at different stages of the development process. Local partners are shown to function as influential mediating agents operating between extrinsic agencies and targeted village groups. They reinforce funding agency planning commitments while also activating economic contingencies and generating alternative development pathways. I also reveal how the structure of technology innovation projects—as either administratively heavy handed or committed to free market principles—influences intermediary behavior, intrapartnership structures of control and, ultimately, development outcomes for targeted artisan communities and households.

The application of multi-region environmental input-output (IO) analysis to the problem of accounting for emissions generation (and/or resource use) under different accounting principles has become increasingly common in the ecological and environmental economics literature, with many applications at the international but fewer at the interregional sub-national level. As an accounting framework, IO tables and IO demand-driven multiplier techniques are absolutely appropriate for conventional pollution attribution analyses because they provide all the required information on pollution embodied in intersectoral interactions and interregional trade flows. However, as a model of how the economy moves from one equilibrium to another in response to a marginal change in activity, IO is unlikely to be appropriate because it is only a very special case of a wider set of general equilibrium approaches. Here, we combine IO accounting with interregional computable general equilibrium (CGE) modelling, adopting Scotland and the rest of the UK as an example. We use the CGE framework to model the impacts of a change in activity and IO analysis for the accounting/attribution analysis of pollution embodied in interregional trade flows (and the interregional CO2 „trade balance‟) before and after the change is introduced.

AbstractIs international migration an adaptation strategy to sudden or gradual climatic shocks? In this paper we investigate the direct and the indirect role of climatic shocks in developing countries as a determinant of out-migration flows toward rich OECD countries in the period 1990–2001. Contrarily to the bulk of existing studies, we use a macro approach and explicitly consider the heterogeneity of climatic shocks (type, size, sign of shocks and seasonal effects). Our results show that the occurrence of adverse climatic events in origin countries has significative direct and indirect effects on out-migration from poor to rich countries.

This paper presents an exergy analysis of an actual two-pass (RO) desalination system with the seawater solution treated as a real mixture and not an ideal mixture. The actual 127 ton/h two pass RO desalination plant was modeled using IPSEpro software and validated against operating data. The results show that using the (ERT) and (PX) reduced the total power consumption of the SWRO desalination by about 30% and 50% respectively, whereas, the specific power consumption for the SWRO per m3 water decreased from 7.2 kW/m3 to 5.0 kW/m3 with (ERT) and 3.6 kW/m3 with (PX). In addition, the exergy efficiency of the RO desalination improved by 49% with ERT and 77% with PX and exergy destruction was reduced by 40% for (ERT) and 53% for (PX). The results also showed that, when the (ERT) and (PX) were not in use, accounted for 42% of the total exergy destruction. Whereas, when (ERT) and (PX) are in use, the rejected seawater account maximum is 0.64%. Moreover, the (PX) involved the smallest area and highest minimum separation work.

The Last Mountain is a 2011 Natural Resources Defense Council (NRDC) film. It examines an aggressive form of strip mining in West Virginia known as mountaintop removal (MTR). The Last Mountain was the first of more than 40 MTR films to be distributed nationally and, as such, marks the entry of the issue onto the political scene in the USA. This essay analyses the film’s use of environmental melodrama to define the problems related to MTR and create identification between victims of MTR and viewers. However, the latter portion of the film attempts to scale up from the melodramatic depiction of MTR to advocacy on broader issues regarding renewable energy and global climate change. In doing so, the film breaks with melodramatic form, draining its emotional power, foreclosing systemic political action, and limiting its overall effectiveness as a sustainability narrative.

We reveal properties of electricity spot prices that cannot be captured by the statistical models, commonly used to model financial asset prices, that are increasingly used to model electricity prices. Using more than eight years of half-hourly spot price data from the New Zealand Electricity Market, we find that the half-hourly trading periods fall naturally into five groups corresponding to the overnight off-peak, the morning peak, daytime off-peak, evening peak, and evening off-peak. The prices in different trading periods within each group are highly correlated with each other, yet the correlations between prices in different groups are lower. Models, adopted from the modelling of security prices, that are currently applied to electricity spot prices are incapable of capturing this behavior. We use a periodic autoregression to model prices instead, showing that shocks in the peak periods are larger and less persistent than those in off-peak periods, and that they often reappear in the following peak period. In contrast, shocks in the off-peak periods are smaller, more persistent, and die out (perhaps temporarily) during the peak periods. Current approaches to modelling spot prices cannot capture this behavior either.

Conventional wisdom holds that OPEC is a weakly functioning cartel with non-OPEC producers forming a “competitive fringe.” However, several studies have challenged the cartel hypothesis for OPEC with a few even challenging the competitive hypothesis for non-OPEC producers. In this paper, we test competing hypotheses (which include dynamic optimization, targetrevenue, competition, cartel, and swing production) for production decisions for both OPEC and non-OPEC producers. Recently developed cost data allow these tests to be done on the most general model to date. In our tests, we find no evidence for dynamic optimization. Formal target-revenue models are rejected, but there is some evidence that revenue targeting may influence production for some OPEC countries and a few non-OPEC countries. We find no evidence that any of the OPEC countries behave in a competitive manner. More surprisingly, we find no evidence that the fringe is competitive. Using cointegration tests, we are unable to find formal evidence of coordination in the form of strict cartel behavior or swing production among OPEC countries. Taken as a whole, the evidence suggests that loose coordination or duopoly is most consistent with OPEC behavior.
