Investments in Biodiversity Prospecting and Incentives for Conservation AgEcon
Sedjo, Roger A.; Simpson, R. David.
There is considerable interest in biodiversity prospecting (the search for valuable new products from natural sources) as a conservation strategy. In an earlier paper, we have argued that the value of the marginal species (and, by extension, the incentives for the conservation of the habitat on which it is found) is small. In this paper, we show that investments in biodiversity prospecting are unlikely to increase incentives for conservation by much. If the value of the marginal species were appreciable, researchers ought already to have made investments to exploit it. If it is not, it is doubtful that additional investments will generate any substantial increase. It is important to be clear about our findings: we are not saying that none of the myriad...

Productive Water Uses at Household Level in Rural Kenya: Case Study of the Ukambani District AgEcon
Speelman, Stijn; D'Haese, Luc; Ochieng, Cosmas M.O.; Vandermeulen, Valerie.
As a result of the growing world population and enhanced by the rising of living standards, competition for water is growing and this causes increased pressure on water resources worldwide. This tendency gave rise to the development of the integrated water resources management approach (IWRM), acknowledging the need to manage water resources in a holistic and integrated way. The IWRM objective to optimize economic, social and environmental outcomes of water management, can however only be reached if impact of water uses is correctly assessed. Nevertheless, often multiple uses of water within sectors are insufficiently recognized in planning and management. One of these neglected uses is the productive water use by households. Nonetheless, this use is...

Valuation Methods for Environmental Benefits in Forestry and Watershed Investment Projects AgEcon
Cavatassi, Romina.
The understatement or omission of the environmental costs and benefits associated with forest management options results in project evaluations and policy prescriptions that are less than socially optimal. The aim of this paper is to examine the full range of costs and benefits associated with forests, distinguishing between how these should, and actually are, included in economic analyses. The paper first describes the economic analysis undertaken in the project evaluation procedure of the World Bank. The second section deals with all costs and benefits that typically occur in forestry projects. Costs and benefits are classified as on-site private, on-site public or global according to their nature and area of impact and according to the Total Economic...

Muddling Through while Environmental Regulatory Capacity Evolves: What Role for Voluntary Agreements? AgEcon
Blackman, Allen; Sisto, Nicholas.
The city of Leon, Guanajuato, is Mexico's leather goods capital and a notorious environmental hotspot. Over the past two decades, four high-profile voluntary agreements aimed at controlling pollution from Leon's tanneries have yielded few concrete results. To understand why, this paper reconstructs the history of these initiatives, along with that of local environmental regulatory capacity. Juxtaposing these two timelines suggests that the voluntary pollution control agreements were both motivated by-and undermined by-gaps in the legal, institutional, physical, and civic infrastructures needed to make regulation effective. Our analysis offers a concrete definition of environmental regulatory capacity, provides insights into how it evolves, and demonstrates...

CURRENT STATE OF THE COTTON AND TEXTILE INDUSTRY IN KAZAKHSTAN AgEcon
Azhimetova, Gulfari.
The textile industry of Kazakhstan is presented basically by enterprises created in period of centrally planned economy and as consequence. Low labor productivity, lacking equipment base and technologies, poor marketing are problems of the current state of industry. But, there are also advantages as a vicinity of potential cotton manufacturers - Uzbekistan, Tajikistan, Turkmenistan. A free economic zone (FEZ) “Ontustik” has been established and a program of “Ontustik” FEZ development has been adopted for developing the cotton and textile cluster in Kazakhstan. The law “About development of the cotton branch” has been adopted in Kazakhstan to provide the textile enterprises with necessary raw material and to develop the domestic cotton growing.

Abatement and Transaction Costs of Carbon-Sink Projects Involving Smallholders AgEcon
Cacho, Oscar J.; Lipper, Leslie.
Agroforestry projects have the potential to help mitigate global warming by acting as sinks for greenhouse gasses. However, participation in carbon-sink projects may be constrained by high costs. This problem may be particularly severe for projects involving smallholders in developing countries. Of particular concern are the transaction costs incurred in developing projects, measuring, certifying and selling the carbon-sequestration services generated by such projects. This paper addresses these issues by analysing the implications of transaction and abatement costs in carbon-sequestration projects. A model of project participation is developed, which accounts for the conditions under which both buyers and sellers would be willing to engage in a carbon...

Energy Consumption and Economic Growth: Evidence from COMESA Countries AgEcon
Chali, Nondo; Mulugeta, Kahsai.
This study applies panel data techniques to investigate the long-run relationship between energy consumption and GDP for a panel of 19 African countries (COMESA) based on annual data for the period 1980-2005. In the first step, we examine the degree of integration between GDP and energy consumption by employing three panel unit root tests and find that the variables are integrated of order one. In the second step, we investigate the long-run relationship between energy consumption and GDP. Results overwhelming show that GDP and energy consumption move together in the long-run. In the third step, we estimate the long-run relationship and test for causality using panel-based error correction models. The results indicate that long-run and short-run causality...

Challenges to Producer Ownership of Ethanol and Biodiesel Production Facilities AgEcon
Kenkel, Philip L.; Holcomb, Rodney B..
This study examines the rapidly expanding biofuels industry and identifies challenges for producer-owned biofuel projects. The U.S. ethanol industry has been growing rapidly, and biodiesel production is poised for similar growth. Producer involvement is driven by the desire to add value to farm commodities and the impact of biofuel projects on local grain prices. Local state and federal incentives have also stimulated producer interest. The long-run profitability of biofuel projects is driven by feedstock availability, access to market centers for biofuels, access to markets for coproducts, and utility costs and availability. The rapidly increasing size and scale of ethanol and biodiesel plants make it difficult for producers to fund these projects....

Macro Economic Impacts of Installing Rice Husk Electricity Power Plants in Thailand AgEcon
Kunimitsu, Yoji; Ueda, Tatsuki.
Macro economic impacts of rice-husk power plants (RHPP) in Thailand were analyzed by an Input/Output method. Results show that RHPP decreased sensitivity coefficients especially in the petroleum-sector, economic merits were realized in the agricultural-sector but total induced production effects were lowered, and induced imports by consumption were reduced with RHPP.

Effects of Poverty on Deforestation: Distinguishing Behavior from Location AgEcon
Kerr, Suzi; Pfaff, Alexander S.P.; Cavatassi, Romina; Davis, Benjamin; Lipper, Leslie; Sanchez, Arturo; Timmins, Jason.
We summarize existing theoretical claims linking poverty to rates of deforestation and then examine this linkage empirically for Costa Rica during the 20th century using an econometric approach that addresses the irreversibilities in deforestation. Our data facilitate an empirical analysis of the implications for deforestation of where the poor live. Without controlling for this, impacts of poverty per se are confounded by richer areas being different from the areas inhabited by the poor, who we expect to find on more marginal lands, for instance less profitable lands. Controlling for locations' characteristics, we find that poorer areas are cleared more rapidly. This result suggests that poverty reduction aids forest conservation.

The Niger Food Crisis: Causes and Implications for Research and Development from an Integrated Agricultural Economics Perspective AgEcon
Abele, Steffen; Twine, Edgar.
During the 2004 food crisis in Niger, the weakness of the main production system, millet, to produce enough food to sustain short term crises, has been revealed. Questions arise how the Nigerian smallholder systems can be assisted by research and development policies to intensify production and improve food security. The paper assesses technical options according to their economic sustainability. A sequence of models is applied: On plot level, production functions of inter cropping systems were estimated to determine yields and their variability of the major crops. These data were fed in a nonlinear program to test the inn ovations, first at stable prices, then at declining prices that were obtained from an interregional trade model. The latter was shocked...

Sustainable Development and Intergenerational Equity: Issues Relevant to India and Globally AgEcon
Tisdell, Clement A..
As outlined, recurring concerns have surfaced since the 1700s that economic growth may prove to be unsustainable. These concerns have been expressed again and have intensified in recent decades but their foundation differs from that of Malthus. The rapid economic growth of China and India have added to these worries. Recent discussions by economists of the desirability of achieving sustainable economic development have mainly focused on measures to attain intergenerational equity in resource use and the dominant view is that each succeeding generation should be at least as well-off as its predecessor. While this is said to be an implication of Rawls’ principle of justice, this dominant rule does not fully reflect Rawls’ principle and it also can violate...

Trade and SPS Regulations: The Importance of Being Earnest? AgEcon
Jouanjean, Marie-Agnes; Le Vernoy, Alexandre.
There is a pending question regarding the impact of food safety standards promulgated by governments or imposed by buyers from the private sector. Their effects on the capacity for developing countries to access developed countries’ markets for high value agricultural and food products is a vivid research theme that up-till-now provided mixed results. While some advocates that food safety standards may hamper exporting abilities, others present evidence that they enable competitiveness and act as a pro-poor growth. This paper contributes to this debate. We offer an analysis on how the intensity of trade flows in fruits and vegetables in Central American countries, Dominican Republic and the U.S. respond to both the level of Sanitary and Phytosanitary...

Bioeconomic Evaluation of Substitution of Balanced Feed with Chaya (Cnidoscolus Chayamansa) Leaves in Tilapia Production AgEcon
Poot-Lope, Gaspar Roman; Gasca-Leyva, Eucario.
In Mexico, the culture of tilapia has developed in rural areas, where the main problem is low producer income. The state of Yucatan also experiences this situation, and scarcity of money needed to purchase inputs results in complementary feeding with chaya (Cnidoscolus chayamansa), whose leaves are edible for humans and animals. In this situation, CINVESTAV conducted experiments to determine the optimal level of substitution of balanced feed with ray chaya leaves. The test with 25% and 50% reduced balanced feed complemented with chaya (ad libitum) did not show significant differences (P>0.05) in growth compared to fishes fed with a complete ration of balanced feed (100% feed table). A bioeconomic model was developed, including a submodel of growth...

Development Aid and the CDM - How to Interpret "Financial Additionality" AgEcon
Dutschke, Michael; Michaelowa, Axel.
International climate negotiations have specified that projects under the Clean Development Mechanism (CDM) should not lead to a "diversion" of official development assistance (ODA). It is however unchallenged that ODA can be used in capacity building for the CDM. Diversion can be interpreted in financial, sectoral and regional terms. There are possibilities to use ODA benchmarks to define diversion such as the UN 0.7% target but they are unlikely to be politically acceptable. On the project level, three main options exist but none of them is perfect. The value of emissions credits (CERs) could be deducted from ODA. This however leads to a long-term pressure on the ODA level. Differentiating an ODA-financed baseline project and a "piggyback" CDM option is...

The Economic Impacts of Biotechnology-Based Technological Innovations AgEcon
Traxler, Greg.
Global adoption of transgenic crops reached 67.7 million hectares in 2003 from 2.8 million in 1996. Delivery has occurred almost entirely through the private sector and adoption has been rapid in areas where the crops addressed serious production constraints and where farmers had access to the new technologies. Three countries (USA, Argentina and Canada), three crops (soybean, cotton and maize) and two traits (insect resistance and herbicide tolerance) account for the vast majority of global transgenic area. While some farmers in some developing countries are benefiting, most do not have access to transgenic crops and traits that address their needs. This paper surveys the level and distribution of the economic impacts of transgenic cotton and soybeans to...

Modeling International Trends in Energy Efficiency and Carbon Emissions AgEcon
Stern, David I..
This study uses a stochastic production frontier to model energy efficiency trends, in 85 countries over a 37 year period. No structure is imposed on technological change over time, although differences in technology level across the countries are modelled as a stochastic function of explanatory variables. These variables are selected by a literature survey and a theoretical model of energy-efficient technology choice. An improvement in a country’s energy efficiency is measured as a reduction in energy intensity, while holding constant that economy’s mix of inputs and outputs. All other things remaining constant, the country using the least energy per unit output is on the global best-practice frontier. The model is used to derive decompositions of...

Wealth, Living Standards and Perceptions in a Cotton Economy: Evidence from the Cotton Reform in Burkina Faso AgEcon
Kaminski, Jonathan.
The cotton economy of Burkina Faso has been characterized by a changing rural environment for farmers since late nineties, which has come with the cotton reform and the resulting cotton boost. There have been slight improvements in living standards and rural households’ income while the subjective feeling of wealth has significantly increased. In this paper, I explore the channels through which the elements of the changing rural environment can bridge the wedge between subjective and objective measures of wealth. In addition to the basic determinants of subjective welfare that can be found in the happiness economics literature, namely absolute and relative income measures, health and social status (and expectations of future incomes), I investigate the...

Political Economy of Agricultural Distortions in Transition Countries of Asia and Europe AgEcon
Rozelle, Scott; Swinnen, Johan F.M..
The paper analyzes the political and institutional factors which are behind the dramatic changes in distortions to agricultural incentives in the transition countries in East Asia (China and Vietnam), Central Asia (Kazakhstan, Kyrgyz Republic, etc), the rest of the former Soviet Union, and in Central and Eastern Europe. The paper explains why these changes have occurred and why there are large differences among transition countries in the extent and the nature of the remaining distortions.
