Claroscuros del desarrollo sustentable y la lucha contra la desertificación: las racionalidades económicas en el ojo de la tormenta : Estudio de caso con productores caprinos de tierras secas (Mendoza, Argentina)

El trabajo analiza la situación de conflicto que se presenta en las tierras secas de Mendoza, entre productores caprinos y programas de lucha contra la desertificación, a propósito de las prácticas productivas y el uso de los recursos naturales.Se aborda un caso de estudio situado en el extremo noreste de la provincia de Mendoza, polo hiperárido de la región, gravemente afectado por procesos de desertificación, con una extensión de 10.007km2 y poblado por 3015 habitantes, donde dominan las pequeñas explotaciones caprinas. Estudios previos señalan que las principales causas de la desertificación de la zona son la tala de bosque nativo y el sobrepastoreo que ocasionan las inadecuadas prácticas de producción ganadera. En respuesta a ello, las acciones de lucha contra la desertificación se orientan a "concientizar" y "capacitar" a los productores e impulsan procesos de cambio productivo. Las propuestas en curso insisten en que, de mantenerse los actuales niveles de presión sobre los recursos, en el futuro se amplificarán las ya graves condiciones de pobreza y desertificación. Sin embargo, a pesar de los esfuerzos y fondos invertidos los productores parecen obstinados en sus actuales estrategias de producción y en la dinámica de uso de los recursos naturales que de ellas derivan. ¿Cómo explicar que no tomen otras opciones productivas que impliquen mayores beneficios económicos y mejores equilibrios ambientales? ¿Cómo explicar que actúen, al menos en apariencia, en contra de sus propios beneficios? Haciendo crítica de las explicaciones que ubican en el epicentro del problema "la cultura" de los productores, este trabajo busca realizar un aporte a través del análisis de tres dimensiones: 1- La oferta ambiental que es soporte de las actividades productivas, 2- Los ingresos que las unidades de producción alcanzan y 3- Los egresos que enfrentan en concepto de subsistencia.

Feeding parameters of copepods from upwelling areas

Feeding patterns of mass herbivorous copepods in upwelling areas are investigated. Daily rations and aspects of their formation are examined in Calanoides carinatus (Benguela upwelling), Calanus pacificus (off the California coast), and Calanus australis (Peru upwelling). Rations were calculated based on gut plant pigment contents obtained at daily stations using laser spectrofluorometry, experimental data on the rate of gut evacuation and data on the carbon/chlorophyll ratio in phytoplankton and particulate matter at the respective stations. When phytoplankton was abundant, diel feeding rhythms were not pronounced and gut pigment level was high during the entire 24-h period. When phytoplankton biomass was low, distinct feeding rhythms were pronounced with a nocturnal maximum. During active upwelling intensive feeding on phytoplankton supports energy (respiration) and plastic (growth, development, reproduction, accumulation of reserves) metabolism of copepods. When upwelling was inactive, the surface part of the population feeds less actively and is able only partially to cover its energy expenditures. The actively growing and reproducing populations of C. pacificus and C. carinatus may consume close to 20% of primary production, whereas the inactive population of C. australis consumed only 0.2% of primary production when upwelling weakened.

A return-on-investment framework to identify conservation priorities in Africa

Environmental conservation activities must continue to become more efficient and effective, especially in Africa where development and population growth pressures continue to escalate. Recently, prioritization of conservation resources has focused on explicitly incorporating the economic costs of conservation along with better defining the outcomes of these expenditures. We demonstrate how new global and continental data that spans social, economic, and ecological sectors creates an opportunity to incorporate return-on-investment (ROI) principles into conservation priority setting for Africa. We suggest that combining conservation priorities that factor in biodiversity value, habitat quality, and conservation management investments across terrestrial, freshwater, and coastal marine environments provides a new lens for setting global conservation priorities. Using this approach we identified seven regions capturing interior and coastal resources that also have high ROI values that support further investment. We illustrate how spatially explicit, yet flexible ROI analysis can help to better address uncertainty, risk, and opportunities for conservation, while making values that guide prioritization more transparent. In one case the results of this prioritization process were used to support new conservation investments. Acknowledging a clear research need to improve cost information, we propose that adopting a flexible ROI framework to set conservation priorities in Africa has multiple potential benefits.

Interactive effects of light, nitrogen source, and carbon dioxide on energy metabolism in the diatom Thalassiosira pseudonana

Due to the ongoing effects of climate change, phytoplankton are likely to experience enhanced irradiance, more reduced nitrogen, and increased water acidity in the future ocean. Here, we used Thalassiosira pseudonana as a model organism to examine how phytoplankton adjust energy production and expenditure to cope with these multiple, interrelated environmental factors. Following acclimation to a matrix of irradiance, nitrogen source, and CO2 levels, the diatom's energy production and expenditures were quantified and incorporated into an energetic budget to predict how photosynthesis was affected by growth conditions. Increased light intensity and a shift from inline image to inline image led to increased energy generation, through higher rates of light capture at high light and greater investment in photosynthetic proteins when grown on inline image. Secondary energetic expenditures were adjusted modestly at different culture conditions, except that inline image utilization was systematically reduced by increasing pCO2. The subsequent changes in element stoichiometry, biochemical composition, and release of dissolved organic compounds may have important implications for marine biogeochemical cycles. The predicted effects of changing environmental conditions on photosynthesis, made using an energetic budget, were in good agreement with observations at low light, when energy is clearly limiting, but the energetic budget over-predicts the response to inline image at high light, which might be due to relief of energetic limitations and/or increased percentage of inactive photosystem II at high light. Taken together, our study demonstrates that energetic budgets offered significant insight into the response of phytoplankton energy metabolism to the changing environment and did a reasonable job predicting them.

Essays on Inequality and Integration

Inequality and integration have been sociology’s two key paradigms since the classics, associated with the names of Marx and Durkheim and Europe’s current economic crisis has forcefully reinvigorated their joint relevance. Above all, the debt crisis has fueled the wheel of social inequality: cash-starved states are further forced to cut back on public expenditures, to minimize the margin for redistribution and to raise new challenges for the integration policies addressing the emerging disparities. At the same time, global environmental and demographic problems, intertwined with escalating migration pressure, tear at the texture of European and all Western societies, in particular, the unequal impact of climate change and the unequal distribution of population growth make migration and integration paramount public policy issues and a soaring source of social conflict. In principle, the inequalities engendered by these cascading processes are also an opportunity. They increase the diversity of society and can bring about innovation and growth. Our desire and ability for social integration depends, above all, on the ultimate balance between these advantages and disadvantages. The chapters in the volume concentrate on the opportunities as well as the risks associated with these social changes from various angles. They are a handpicked set of outstanding contributions from the Congress of the Swiss Sociological Association that took place at the University of Bern, June 26–28, 2013.

Crowding-out and Crowding-in Effects of Government Bonds Market on Private Sector Investment (Japanese Case Study)

This paper reviews the relationship between public sector investment and private sector investment through government expenditures financed by government bonds in the Japanese economy. This study hypothesizes that deficit financing by bond issues does not crowd out private sector investment, and this finance method may crowd in. Thus the government increases bond issues and sells them in the domestic and international financial markets. This method does not affect interest rates because they are insensitive to government expenditures and they depend on interest rates levels in the international financial market more than in the domestic financial market because of globalization and integration among financial markets.

The Impact of Tobacco Production Liberalization on Smallholders in Malawi

Burley tobacco production in Malawi was liberalized to permit production by smallholders in the early 1990s. The purpose of this paper is to show which smallholders began producing burley tobacco after liberalization and which smallholders still continue to produce it. Analysis of the characteristics of burley tobacco producers shows that only smallholders who had adequate farm size and adequate funds could start to produce it. With regard to the farm size requirements, only smallholders who had enough acreage to sell tobacco on the auction floors and who had enough acreage to rotate crops could start to produce. With regard to the financial requirements, only smallholders who could procure funds through informal institutions or who possessed their own capital to meet the necessary agricultural expenditures could start. So, it was only the wealthy households which could start to produce tobacco after liberalization and continue to produce it.

Liability dollarization and fear of floating

This paper explores the idea that fear of floating can be justified as an optimal discretionary monetary policy in a dollarized emerging economy. Specifically, I consider a small open economy in which intermediate goods importers borrow in foreign currency and face a credit constraint. In this economy, exchange rate depreciation not only worsens importers' net-worth but also increases the financing amount in domestic currency, therefore exaggerating their borrowing finance premium. Besides, because of high exchange rate pass-through into import prices, fluctuations in the exchange rate also have strong impacts on domestic prices and production. These effects, together, magnify the macroeconomic consequences of the floating exchange rate policy in response to external shocks. The paper shows that the floating exchange rate regime is dominated by the fixed exchange rate regime in the role of cushioning shocks and in welfare terms.

Determinants of government consumption expenditure in developing countries : a panel data analysis

The paper focuses on the recent pattern of government consumption expenditure in developing countries and estimates the determinants which have influenced government expenditure. Using a panel data set for 111 developing countries from 1984 to 2004, this study finds evidence that political and institutional variables as well as governance variables significantly influence government expenditure. Among other results, the paper finds new evidence of Wagner's law which states that peoples' demand for service and willingness to pay is income-elastic hence the expansion of public economy is influenced by the greater economic affluence of a nation (Cameron1978). Corruption is found to be influential in explaining the public expenditure of developing countries. On the contrary, size of the economy and fractionalization are found to have significant negative association with government expenditure. In addition, the study finds evidence that public expenditure significantly shrinks under military dictatorship compared with other form of governance.

Chapter 6 Economic integration and changes in industrial location in Vietnam

Vietnam has been praised for its achievements in economic growth and success in poverty reduction over the last two decades. The incidence of poverty reportedly fell from 58.1% in 1993 to 19.5% in 2004 (VASS [2006, 13]). The country is also considered to have only a moderate level of aggregate economic inequality by international comparisons. As of the early 2000s, Vietnam’s consumption-based Gini coefficient is found to be comparable to that of other countries with similar levels of per capita GDP. The Gini index did increase between 1993 and 2004, but rather slowly, from 0.34 to 0.37 (VASS [2006, 13]). Yet, as the country moves on with its market oriented reforms, the question of inequality has been highlighted in policy and academic discourses. In particular, it is pointed out that socio-economic inequalities between regions (or provinces) are significant and have been widening behind aggregate figures (NCSSH [2001], Mekong Economics [2005], VASS [2006]). Between 1993 and 2004, while real per capita expenditure increased in all regions, it grew fastest in those regions with the highest per capita expenditures and vice versa, resulting in greater regional disparities (VASS [2006, 37]). A major contributing factor to such regional inequalities is the uneven distribution of industry within the country. According to the Statistical Yearbook of Vietnam, of the country's gross industrial output in 2007, over 50% belongs to the South East region, close to 25% to the Red River Delta, and about 10% to the Mekong River Delta. All remaining regions share some 10% of the country's gross industrial output. At a quick glance, the South East increased its share of the total industrial gross output in the 1990s, while the Red River Delta started to gain ground in more recent years. How can the government deal with regional disparities is a valid question. In order to offer an answer, it is necessary in the first place to grasp the trend of disparities as well as its background. To that end, this paper is a preparatory endeavor. Regional disparities in industrial activities can essentially be seen as a result of the location decisions of enterprises. While the General Statistics Office (GSO) of Vietnam has conducted one enterprise census (followed by annual enterprise surveys) and two stages of establishment censuses since 2000, sectorally and geographically disaggregated data are not readily available. Therefore, for the moment, we will draw on earlier studies of industrial location and the determinants of enterprises’ location decisions in Vietnam. The remainder of this paper is structured as follows. The following two sections deal with the country context. Section 2 will outline some major developments in Vietnam’s international economic relations that may affect sub-national location of industry. According to the theory of spatial economics, economic integration is seen as a major driver of changes in industrial location, both between and within countries (Nishikimi [2008]). Section 3, on the other hand, will consider some possible factors affecting geographic distribution of industry in the domestic sphere. In Section 4, existing literature on industrial and firm location will be examined, and Section 5 will briefly summarize the findings and suggest some areas for future research.

Myanmar's two decades of partial transition to a market economy : a negative legacy for the new government

Despite more than two decades of transition from a centrally planned to a market-oriented economy, Myanmar’s economic transition is still only partly complete. The government’s initial strategy for dealing with the swelling deficits of the state economic enterprises (SEEs) was to put them under direct control in order to scrutinize their expenditures. This policy change postponed restructuring and exacerbated the soft budget constraint problem of the SEEs. While the installation of a new government in March 2011 has increased prospects for economic development, sustainable growth still requires full-scale structural reform of the SEEs and institutional infrastructure building. Myanmar can learn from the gradual approaches to economic transition in China and Vietnam, where partial reforms weakened further impetus for reforms.

Estimating the effect of chemical safety standards on firm performance in Malaysia and Vietnam

This paper uses firm-level data to examine the impact of chemical safety regulations imposed by importing countries such as RoHS and REACH on the production costs and export performance of firms in Malaysia and Vietnam. We find that in addition to the initial setup costs for compliance, EU RoHS and REACH implementation causes firms to incur additional variable production costs by requiring additional labor and capital expenditures of around 12% of the variable costs, respectively. We also find that compliance with RoHS and REACH significantly increases the probability of export. Furthermore, we find that compliance with EU RoHS and REACH helps firms to penetrate into a greater variety of countries. Also, we find that multinational enterprises and firms participating in global value chains generally exhibit better export performance and their costs rise less steeply.
