We propose an ethical analysis as a method to reflect on how companies’ decisions promote sustainable development. The method proceeds by first identifying the choice according to financial business interests, and by then scrutinizing this choice according to consequentialist and deontological ethics. The paper applies the method to the choice of an Environmental Impact Assessment (EIA) that a consortium of Brazilian companies (EGASUR) delivered as part of their project proposal for the realization of the Inambari hydropower dam in the Peruvian Amazon. We show that if an EIA is chosen based on the attempt to maximize the financial bottom line, it raises ethical issues both from a consequentialist perspective by involving negative consequences for various stakeholder groups, and from a deontological perspective by not complying with relevant rules, guidelines, and principles. The two ethical perspectives hence reveal where the consortium faces impediments to a genuine commitment to sustainability. Building on stakeholder interviews, observations of the project developments, and the executive summary of the actual EIA, we provide indications that EGASUR has indeed made a choice that resembles a decision based on financial interests.

It is often said that innovations create winners and losers. All innovations are somewhat disruptive, but some have more distributed effects. We have a sense of who the winners are and how much they gain. Yet, how much do losers actually lose? Organic farmers frequently like to publicly announce that they are the losers following the commercialization of genetically modified (GM) crops, yet consumers in search of non-GM products have helped increase demand for organic products, something that would not have occurred in the absence of GM crops. Are organic farmers really losers? This article lays out the argument that were it not for the commercialization of GM crop varieties in the mid-1990s, organic production and food sectors would not be at the level they enjoy today. That is, the commercialization of GM crops has made the organic industry better off than had GM crops not been commercialized. Theoretical modelling of the organic benefits is complemented by supportive market data. The article concludes that in spite of numerous vocal offerings about the adverse impacts suffered by the organic industry due to GM crop production, the organic industry has gained significantly from that which they vociferously criticize.

Deciding upon optimum planning actions in terms of sustainable urban planning involves the consideration of multiple environmental and socio-economic criteria. The transformation of natural landscapes to urban areas affects energy and material fluxes. An important aspect of the urban environment is the urban metabolism, and changes in such metabolism need to be considered for sustainable planning decisions. A spatial Decision Support System (DSS) prototyped within the European FP7-funded project BRIDGE (sustainaBle uRban plannIng Decision support accountinG for urban mEtabolism), enables accounting for the urban metabolism of planning actions, by exploiting the current knowledge and technology of biophysical sciences. The main aim of the BRIDGE project was to bridge the knowledge and communication gap between urban planners and environmental scientists and to illustrate the advantages of considering detailed environmental information in urban planning processes. The developed DSS prototype integrates biophysical observations and simulation techniques with socio-economic aspects in five European cities, selected as case studies for the pilot application of the tool. This paper describes the design and implementation of the BRIDGE DSS prototype, illustrates some examples of use, and highlights the need for further research and development in the field.

The past two decades have seen an impressive expansion of municipal engagement with climate change. Yet while interest has broadened, actions remain shallow. This is in part because climate policies fit uneasily into existing bureaucratic structures and practices. Effective climate programmes require adaptive and innovative responses that span departmental divisions. This challenges siloised municipal offices that are embedded in their own organisational cultures and technical practices. Understanding those challenges is crucial to understanding urban responses to climate change, but they remain critically understudied. This paper helps to fill that gap by looking at the experiences of two cities, Durban (KZN, South Africa) and Portland (OR, USA) as they attempt to put in place integrated responses to climate change. To do so, it brings together complementary critical perspectives drawn from the study of bureaucracies and complex institutions in sociology and geography. This hybrid critical framework is used to elaborate on both the organisational barriers that inhibit effective responses to climate change, and approaches that can be used to enable change and innovation.

Biofuel plantations have been hyped as a means to reinvigorate Africa’s rural areas. Yet there is still apprehension about the negative environmental and social impacts of large-scale commercial biofuel production around rising food prices, land grabbing, ecological damage, and disruption of rural livelihoods. Given the extent of Jatropha curcas production in Ghana and Ethiopia and Castor bean (Ricinus communis) in Ethiopia, this paper presents the results of a study that assessed the socio-economic implications of industrial Jatropha plantations on local livelihoods in Ghana, and of industrial Jatropha and Castor plantations on local livelihoods in Ethiopia. This study used primary data collected from 234 households in Ghana and 165 in Ethiopia. The cultivation of Jatropha and Castor has had several important effects on local livelihoods in the study sites, most notably decreases in household landholdings due to the arrival of industrial Jatropha or Castor plantations; and the resulting changes these plantations have caused in household socio-economic status, food security, fallow periods, and fodder availability. We consider how a lack of meaningful consultation between local people, their traditional authorities and the biofuel company managers, along with shortcomings in each country’s broader land acquisition process and poor land use information, may have contributed to these overall negative effects on local livelihoods. We conclude by suggesting several ways that emerging biofuel industries could be improved from the perspective of local people and their livelihoods.

The purpose of this paper is to introduce the concept of power density [Watts/m²] into economics. By introducing an explicit spatial structure into a simple general equilibrium model we are able to show how the power density of available energy resources determines the extent of energy exploitation, the density of urban agglomerations, and the peak level of income per capita. Using a simple Malthusian model to sort population across geographic space we demonstrate how the density of available energy supplies creates density in energy demands by agglomerating economic activity. We label this result the density-creates-density hypothesis and evaluate it using data from pre and post fossil-fuel England from 1086 to 1801.

More than40%of US grain is used for energy due to the Renewable Fuel Mandate (RFS). There are no studies of the global distributional consequences of this purely domestic policy. Using micro‐level survey data, we trace the effect of the RFS on world food prices and their impact on household level consumption and wage incomes in India. We first develop a partial equilibrium model to estimate the effect of the RFS on the price of selected food commodities—rice, wheat, corn, sugar, and meat and dairy, which together provide almost70%of Indian food calories. Our model predicts that world prices for these commodities rise by 8–16%due to the RFS. We estimate the price pass‐through to domestic Indian prices and the effect of the price shock on household welfare through consumption and wage incomes. Poor rural households suffer significant welfare losses due to higher prices of consumption goods, which are regressive. However, they benefit from a rise in wage incomes, mainly because most of them are employed in agriculture. Urban households also bear the higher cost of food, but do not see a concomitant rise in wages because only a small fraction of them work in food‐related industries. Welfare losses are greater among urban households. However, more poor people in India live in villages, so rural poverty impacts are larger in magnitude. We estimate that the mandate leads to about 25 million new poor: 21 million in rural and 4 million in the urban population.
