The Effects of Corruption Control and Political Stability on the Environmental Kuznets Curve of Deforestation-Induced Carbon Dioxide Emissions

This article formulates a structural empirical model that measures the short run and long run effect of economic growth, political stability and corruption control on carbon dioxide (CO2) emissions from deforestation. Income has a negative effect on forest cover in the short run but it does not have any long run effect. In contrast, political stability and corruption have relatively smaller effects on forest cover in the short run but they have lingering long run effects. We derive a U-shaped forest-income curve where political stability and corruption control do not significantly affect the income turning point but both variables shift the curve up or down. The resulting CO2 emission-income curve is downward sloping and is based on changes in the levels of variables affecting forest cover. Increased political stability flattens the CO2 emissions-income curve leading to smaller changes of CO2 emissions per unit change in income.Deforestation, Environmental Kuznets Curve, Political stability

Governance and Deforestation Due to Agricultural Land Expansion

This article examines the effect of governance on forest cover in developing countries. We develop a theoretical model that explains how governance, particularly corruption control and politically stability, affects deforestation due to agricultural land expansion. The theoretical model shows the importance of the complementarity or substitutability of technology and land use in determining the effect of governance on agricultural land expansion and, consequently, forest cover. We complement the theoretical model with a structural empirical analysis to measure the effect of corruption control and political stability on deforestation in developing countries through two direct channels of deforestation: agricultural land expansion and road building. We find that political stability has a positive and significant effect on forest cover but corruption control has a negative and significant effect on forest cover due to increased agricultural land expansion.Deforestation, Governance, Corruption, Political stability

How substitutable is natural capital ?

One of the recurring themes in the sustainability literature has been the legitimacy of using an economic framework to account for natural resources. This paper examines the potential for substituting between different inputs in the generation of income, where the inputs include natural resources such as land and energy resources. A nested constant elasticity of substitution (CES) production function is used to allow flexibility in the estimated elasticities of substitution. Also, with this specification, natural resources and other inputs are combined in different levels of the function, thus allowing for different levels of substitutability. Institutional and economic indicators are also incorporated in the production function estimated. Results show that the elasticities derived from functions involving land resources were generally around one or greater, implying a fairly high degree of substitutability. Furthermore, changes in trade openness and private sector investment have a statistically significant and direct relationship with income generation. No statistically significant relationship between income and any of the institutional indicators was found.Economic Theory&Research,Inequality,Economic Growth,Banks&Banking Reform,Climate Change

2010 Estimated Cost of Producing Hops in the Yakima Valley, Washington State

The enterprise budget provides estimates of production costs for a well-managed hop enterprise in Yakima Valley, Washington as of 2010. Three producer scenarios are presented to demonstrate how the enterprise budget can be used to evaluate situations in which the producer may find him/herself. An interactive Excel Workbook is developed and detailed instructions are provided to allow users to input their own data or make changes to the existing spreadsheets.enterprise budget, hops, Washington

Economic Impacts of the Elimination of Azinphos-methyl on the Apple Industry and Washington State

The Environmental Protection Agency has declared the organophosphate pesticide azinphos-methyl (AZM) cannot be used in the production of apples after September 30, 2012. We estimate the change to sales, price, and employment to the Washington State apple industry from using the likely AZM alternative had this ban been in effect in 2007. Furthermore, we estimate the effects of this ban as it ripples through the overall Washington State economy. We find the ban will bring a relatively modest change to sales (-0.8%), prices (0.2%), and employment (0.1%) in the apple industry, with negligible impacts on the overall Washington State economy.apples, azinphos-methyl, economic impact, computable general equilibrium

The Economic Value of Biochar in Crop Production and Carbon Sequestration

This paper estimates the economic value of biochar application on agricultural cropland for carbon sequestration and its soil amendment properties. In particular, we consider the carbon emissions avoided when biochar is applied to agricultural soil, instead of agricultural lime, the amount of carbon sequestered, and the value of carbon offsets, assuming there is an established carbon trading mechanism for biochar soil application. We use winter wheat production in Eastern Whitman County, Washington as a case study, and consider different carbon offset price scenarios and different prices of biochar to estimate a farm profit. Our findings suggest that it may be profitable to apply biochar as a soil amendment under some conditions if the biochar market price is low enough and/or a carbon offset market exists.Biochar, Carbon sequestration, Crop, Farm profitability, Soil amendment

Economic tradeoff between biochar and bio-oil production via pyrolysis

This paper examines some of the economic tradeoffs in the joint production of biochar and bio-oil from cellulosic biomass. The pyrolysis process can be performed with different final temperatures, and with different heating rates. While most carbonization technologies operating at low heating rates result in higher yields of charcoal, fast pyrolysis is the technology of choice to produce bio-oils. Varying operational and design parameters can change the relative quantity and quality of biochar and bio-oil produced for a given feedstock. These changes in quantity and quality of both products affect the potential revenue from their production and sale. We estimate quadratic production functions for biochar and bio-oil. The results are then used to calculate a product transformation curve that characterizes the yields of bio-oil and biochar that can be produced for a given amount of feedstock, movement along the curve corresponds to changes in temperatures, and it can be used to infer optimal pyrolysis temperature settings for a given ratio of biochar and bio-oil prices.biochar, bio-oil, pyrolysis, biomass conversion, economic tradeoff

2022 cost estimates of establishing and producing organic 'Elliott' blueberries in Eastern Washington

The results presented in this WSU publication serve as a general guide for evaluating the feasibility of producing organic 'Elliott' blueberries in eastern Washington in 2022. The primary use of this publication is in identifying inputs, costs, and yields considered typical of well-managed 'Elliott' blueberry fields. This publication is not intended to be a definitive guide to production practices, but it is intended to be helpful in estimating the physical and financial requirements of comparable plantings. Cost estimations in the enterprise budget also vary depending on its intended use. To avoid drawing unwarranted conclusions about any particular farm, readers must closely examine the assumptions made in this guide and then adjust the costs, returns, or both as appropriate for their farm operation

Will Washington Provide Its Own Feedstocks for Biofuels?

The study finds that Washington State’s field corn, sugar beet and canola production could satisfy only a small percentage of the State’s annual gasoline or diesel consumption. Linear programming projections for 2008 showed a relatively close match between projected and actual production. Projections for 2009-2011 showed no increase in the State’s capacity to increase biofuel crop feedstocks. In comparison to crop feedstocks, Washington’s total annual lignocellulosic biomass is abundant. However, only a fraction of the biomass could be converted to biofuel due to high costs of collection and processing, competing markets for some biomass, and limitations in current technology.biofuels, biofuel feedstocks, canola, cellulosic inventories, grain corn, linear programming, Washington State
