The Clean Energy Dilemma in Asia: Is There a Way Out?

A prominent American geographer and specialist on energy and environmental policies in developing countries assesses the challenge to sustainable development posed by Asia's rapid economic growth and the concurrent need to reduce the environmental impacts of energy production and use. A particular focus is on China and India, as rapidly growing energy consumers and greenhouse gas emitters, and on Russia as a potentially important supplier of natural gas and liquid alternatives to coal use. The author suggests some elements of a strategy to resolve the dilemma of reducing global environmental impacts without penalizing Asia's economic development, although a significant energy transition over the next several decades appears quite difficult.     

Household Incomes in Central Asia: The Case of Post-Soviet Kazakhstan

Two European geographers present the findings of a sizeable survey (n = 7,515) providing a detailed geographical analysis of household incomes and reliance on personal subsidiary garden plots across Kazakhstan. The authors focus on assessing the extent to which Kazakhstan's rising GDP during the post-Soviet period has coincided with an increase in the general population's personal income and ability to secure adequate food supplies for personal consumption. The fine geographical scale of analysis of the survey data (significantly less coarse than oblast-level data) enabled them to identify regions characterized by "trickle-down" income, largely centered on the country's two main urban centers and areas of resource exploitation. The patterns revealed in the paper have relevance to the debate concerning the uneven distribution of benefits from resource exploitation (notably oil and gas) to Kazakhstan's population.

India's Energy Security: Challenges and Opportunities

A noted specialist on India's energy security reviews the range of energy-related issues that will have a bearing on that country's ability to sustain the high current rates of economic growth and development into the future. The author explores the multiple challenges India confronts in securing (through domestic production and external sources) an adequate mix of energy supplies (hydrocarbon fuels, nuclear power, renewable energy sources) and describes as well as analyzes a broad front of actions (both government programs and the activities of private companies) taken to address them. The analysis illuminates India's important role in the production and consumption of several forms of energy.

Some Results and Prospects of Research on the Productivity of Forest Biogeocenoses

A review of Soviet research on the productivity of forest biogeocenoses finds confusion in terminology and urges general agreement on specific concepts and terms. Research has thus far been limited to the plant aspect of the forest communities, ignoring the animal and microbial communities. Changes in the amount of litter fall and phytomass from one natural zone to another are analyzed for spruce and oak communities and for forest biogeocenoses of various ages. A program for future research is outlined.     

Toward an understanding of the exchange in ancient scented oils through organic residue analysis of Bronze Age Near Eastern ceramic bottles by GC-MS

This paper presents a gas chromatography-mass spectrometry (GC-MS) organic residue analysis (ORA) of samples extracted from five Early Bronze Age ceramic bottles excavated at the archaeological site of Küllüoba in Anatolia (modern Turkey), and the first attempt at directly analysing the content of this category of products. Our results show that various types of liquid have been contained in different bottles and identify the presence of dicarboxylic and oleic acids with a large amount of palmitic acid in most samples, suggesting that they may have mostly contained a plant-based oil. The presence of diterpenoids further shows the addition of ingredients such as conifer resin and other plant-derived products. Overall, the analytical results presented here indicate the exchange of scented oils in Anatolia already during the late third millennium BCE. The different organic residue profiles contained in different samples also suggest a range of different recipes for these products.     

Physico‐Chemical Characterization of Pigments and Binders of Murals in a Church in Ethiopia

Here, we report the physico‐chemical characterization of wall paintings from the Petros and Paulos church in Ethiopia. This work represents the first technical study of paintings located in Ethiopia, rather than paintings in museum collections outside the country, using diverse analytical techniques. In situ examination with a portable X‐ray fluorescence spectrometer (pXRF) was followed by analysis of samples using optical microscopy (OM), scanning electron microscopy coupled with energy‐dispersive X‐ray spectroscopy (SEM/EDS), micro‐Raman spectroscopy (MRS), attenuated total reflection – Fourier transform infrared spectroscopy (ATR‐FT–IR), X‐ray powder diffraction (XRD) and pyrolysis gas chromatography – mass spectrometry (Py‐GC/MS). The paint stratigraphy, the compositions of the support material, the preparatory and painting layers were studied, as well as the morphology of the pigment particles. The results revealed the use of earth pigments and carbon black. The preparatory layer was uncommon; composed of dolomite, clay rich in clinochlore and sand, in contrast to the more common gypsum and calcite. The binder and the stratigraphic analyses suggested a distempera technique.     

Applying Policy Termination Theory to the Abandonment of Climate Protection Initiatives by U.S. Local Governments

A considerable amount is known about the factors that influence policy adoption and implementation across different issue areas. Less is known, however, about the factors that influence governments to abandon programs or policies prior to reaching their stated objectives or originally specified end‐points. This article applies termination theory to local climate protection initiatives and examines cities’ withdrawal from the dominant sustainability organization facilitating these efforts. In the face of national government inaction, large numbers of U.S. municipalities voluntarily committed to reduce their greenhouse gas (GHG) emissions and joined the ICLEI's Climate Protection program. After steady membership increases for nearly a decade, ICLEI attained its largest size in 2010 with 565 city members. Over the next 2 years, this number plummeted by 20 percent. Positioned in the literature on policy change, we empirically test three hypotheses for why a substantial portion of cities ended their affiliation with this organization and terminated the explicit climate protection objectives associated with it: (1) political ideology and interest group pressure, (2) fiscal constraints, and (3) perceived program ineffectiveness. Analytical results support the first and third hypotheses. We identify factors that influence the termination of local GHG reduction initiatives and discuss theoretical implications of these findings.

Gas breakthrough experiments on pelitic rocks: comparative study with N2, CO2 and CH4

The capillary‐sealing efficiency of intermediate‐ to low‐permeable sedimentary rocks has been investigated by N₂, CO₂ and CH₄ breakthrough experiments on initially fully water‐saturated rocks of different lithological compositions. Differential gas pressures up to 20 MPa were imposed across samples of 10–20 mm thickness, and the decline of the differential pressures was monitored over time. Absolute (single‐phase) permeability coefficients (k_abs), determined by steady‐state fluid flow tests, ranged between 10^?22 and 10^?15 m². Maximum effective permeabilities to the gas phase k_eff(max), measured after gas breakthrough at maximum gas saturation, extended from 10^?26 to 10^?18 m². Because of re‐imbibition of water into the interconnected gas‐conducting pore system, the effective permeability to the gas phase decreases with decreasing differential (capillary) pressure. At the end of the breakthrough experiments, a residual pressure difference persists, indicating the shut‐off of the gas‐conducting pore system. These pressures, referred to as the ‘minimum capillary displacement pressures’ (P_d), ranged from 0.1 up to 6.7 MPa. Correlations were established between (i) absolute and effective permeability coefficients and (ii) effective or absolute permeability and capillary displacement pressure. Results indicate systematic differences in gas breakthrough behaviour of N₂, CO₂ and CH₄, reflecting differences in wettability and interfacial tension. Additionally, a simple dynamic model for gas leakage through a capillary seal is presented, taking into account the variation of effective permeability as a function of buoyancy pressure exerted by a gas column underneath the seal.
