Optimizing the Spatial Structure of the Agricultural Production Function

Important characteristics of spatial agricultural production functions are derived by introducing a non‐negative curvilinear spatial demand function for production input intensities. Given the usual neoclassical rationale assumptions of spatial demand for capital and labor inputs under competitive environment of farming in developing agricultural economies, the optimal production levels are determined by optimizing spatial demand for production inputs. Decreasing price‐to‐transport costs ratio (that is, decrease in the prices of capital goods or increase in freight rates) and increasing wage‐to‐travel costs ratio (that is, increase in labor wages or decrease in the travel rate) expand the limits of the (spatial) optimal boundary of the demand for agricultural capital goods and labor input respectively. These effects occur on account of the operation of (positive) spatial price gradient and (negative) wage‐gradient in the market region. It may be noted that elasticities of demand for production factors are spatially variant and have significant effects on the alterations in the structure of agricultural production. However, the spatial optimal solution of production has a complicated relationship with them. The price elasticity has negative and wage elasticity has positive spatial gradients in the market region. Farmers located in the periphery of the market region are not much affected by the proportionate changes occurring in the prices of agricultural capital goods but are more sensitive to the proportional changes in labor wages. Because of a decreasing trend in capital input demand and increase in labor input with distance from the market, capital‐product diminishes with a decreasing rate and labor‐product increases with an increasing rate in the spatial structure of agricultural production. As a result, capital‐labor ratio falls toward zero, which raises profit rate per unit of capital investment especially in the outer part of the market region. The equilibria of optimal production with price elasticity as well as of capital intensity with labor employment (that is, capital‐labor ratio as unity) determine spatial limits of the optimal production zone which is shifted outward subject to the provision of cheap transportation, stabilizing market prices and/or increasing wage rate at the market center. It will help in extending outwardly the optimal spatial limits of capital investment and will mobilize capital resources of farmers in the periphery for efficient and competitive capital‐dominated farming.     

Environmental Relations and Biophysical Transition: The Case of Trinket Island

ABSTRACT To what extent is an island economy cut off from the rest of the world? Defined as a mass of land bounded by water, island societies connect and exchange with their surroundings rather intensely. Based on empirical research, this paper explores the role of a ‘remote’ island society on Trinket in generating or sheltering itself from the process of globalisation in which con‐textually given borders are transgressed and displaced. To this end, we apply the concepts of societal metabolism and colonising natural processes operationalised by Material and Energy Flow Analysis (MEFA), and Human Appropriation of Net Primary Production (HANPP) respectively. Using these biophysical indicators, we describe the transition from a metabolism based upon the natural environment to metabolism based on exchange with other societies. Data presented in this paper further reveal a process of industrialisation and integration into the global market of a so‐called ‘closed’ and ‘inaccessible’ island society.     

World Bank‐directed Development? Negotiating Participation in the Nam Theun 2 Hydropower Project in Laos

The omnipotence of the World Bank on a global scale means that it is often regarded as the most influential partner in bringing about transformations in developing countries. This article contributes to ongoing discussions of this issue by examining some effects of the Bank's participatory agenda in one of its flagship projects, the Nam Theun 2 (NT2) hydropower scheme in Laos. Critical accounts suggest that the Bank's promotion of participation in donor‐dependent countries like Laos is either a guise or an imposition. These propositions are considered in two settings where participation was debated around the time of the Bank's loan appraisal for NT2: first, an international stakeholders’ workshop held in Vientiane; and second, some international attempts to identify the concerns of villagers living near the NT2 dam site. In workshops and villages, participation is a negotiated performance whereby competing representations emerge through the interaction between village, state and international actors. More generally, this article shows that a grounded view of development can attend to the practices that constrain the hegemonic tendencies of the World Bank, even while maintaining awareness of the potency of its policies and interventions.     

The Arab Opposition Molehill

Arab Islamic oppositions have proven largely ineffectual in molding regime outcomes since the liberalizations of the 1980s and 1990s, although many continue to overestimate their potential for propelling reform. This article argues that a keen sense of the past is necessary when evaluating whether or not an opposition matters for political reform. Section I introduces noted scholar Juan Linz's notion of “semi‐opposition”—limited and “semi‐free” opposition groups that may sustain authoritarian regimes as much as repression. Using interviews and English and Arabic sources, Section II demonstrates historical correspondences between semi‐opposition and the Jordanian and Egyptian Muslim Brotherhood (MB) organizations concerning origins and support, ideology and approach to politics, regime tolerance and political environment, and political behavior. Section III develops Linz's hypothesis on the links between semi‐opposition and authoritarian persistence by examining how the MB marginalizes and raises the costs of dissent for other opposition groups and actors. The MB is briefly contrasted with the Algerian Front Islamique du Salut (FIS) opposition party of 1989–1992 in Section IV . Decidedly not a semi‐opposition, the FIS proved far more transformative than either the Jordanian or Egyptian MB, inducing centrifugal politics and the collapse of the Front de Libération Nationale (FLN) state that governed Algeria from 1962.     

Spondylodendron pranabii—the dominant lycopsid of the late Mississippian vegetation of the Kashmir Himalaya

Cleal, C.J., Bhat, G.M., Singh, K.J., Dar, A.M., Saxena, A. & Chandra, S., February 2016. Spondylodendron pranabii—the dominant lycopsid of the late Mississippian vegetation of the Kashmir Himalaya. Alcheringa 40, xxx–xxx. ISSN 0311-5518.

The Sepukhovian fossil floras of the northern margins of Gondwana, on the shores of the Palaeotethys, are dominated by remains of an eligulate, mainly monopodial lycopsid with persistent leaves. The stems show considerable morphological and preservational variation that has historically resulted in the fossils having been assigned to many fossil-species and -genera. However, there is now clear evidence that this simply reflects variation within a single fossil-species, reflecting biological variation and the effects of variable taphonomy, for which the correct taxonomic name is Spondylodendron pranabii (Pal) comb. nov. Part of this morphological variation might have been due to variations in growth rate during the life of the individual plants, which in turn might reflect stressed growing conditions in a wetland habitat. The systematic position of Spondylodendron remains uncertain, owing to the lack of unequivocal evidence of reproductive structures, but it might have affinities with the Sublepidodendraceae.

Initial evidence of plant and animal-origin organic additives from the second-century bce earthen plaster of rock-cut caves of Karla,India*

Analytical investigations through phytochemical screening, scanning electron microscope (SEM) and light microscopic observation of the earthen plaster of Karla Caves of western India identified the presence of antifungal, antibacterial and insect repellent Careya arborea stem fibres as a vegetal additive. The scanning electron microscopy with energy-dispersive X-ray spectrometry (SEM-EDX) study also revealed the inclusion of rice (Oryza sativa) husk as a plant additive in the plaster. In the high rain-fed coastal regions of western India, the antimicrobial, antioxidant and termite-resistance properties of C. arborea helped the survival of the plaster in unfavourable climatic conditions. Besides, the C. arborea and rice husk together played a role in reducing cracks, decreasing the density, and imparting a plasticity and a durability to the plaster. The liquid Fourier-transform infrared spectrometer (FTIR) of organic extracts revealed carboxylic acid (fatty acids)-based additives in the earthen plaster. From the gas chromatography-mass spectrometry (GC-MS) analysis of the plaster, the presence of animal milk fat, animal and vegetable fat, and vegetable oil was identified, and probably used to strengthen the earthen plaster for their resistance to tensile stress. The analysis also diagnoses the inclusion of methyl commate B, a resinous material obtained from the Burseraceae plant family, which has antimicrobial properties, through GC-MS analysis.     

The effects of microfinance programs on women members in traditional societies

One of the stated goals of microfinance programs is to increase the bargaining power of women within the household. However, little is known about other ways women in patriarchal communities may be affected by these programs. This study assessed the effects of the membership in a microfinance joint liability group (MJLG) on the lives and social networks of its women members by focusing on the interplay of MJLG practices and gendered cultural practices such as ‘purdah’ (veiling of the face). Using in-depth interviews of 35 women in Lucknow, a city in northern India, the study found that, overall, respondents who were members of an MJLG reported developing new and stronger relationships with other members of the group. These social interactions were found to be deeper among women who were using the microloans for self-employment than among women who were redirecting their loan funds to other family members. The study also found that the adaptability of microfinance organizations to the local culture appeared to enable women to join MJLGs with ease and to contribute economically to their families.
