The Climate Justice Movement in Western New York

Although climate change requires an international response and will require national policies and actions, local geographies have to be involved because it that is where the harms are felt. But how can local and regional areas respond to the climate crisis? This article offers a story of the emergence of a climate justice movement in Buffalo and Western New York as an example of how one community is addressing climate change and its unequal impacts

European Transport Policy and Cohesion - An Assessment by CGE Analysis

This paper studies the spatial impact of two main aspects of European transport policy, namely infrastructure investments and pricing. In its "White Paper: European Transport Policy for 2010: Time to Decide" the European Commission has laid down a comprehensive programme of transport policy within the EU, aiming at increasing the efficiency of the transport industry, developing the so-called trans-European infrastructure network and bringing the prices of transport services closer to the true marginal social cost. It is an important political issue whether the policy will enhance spatial cohesion in Europe or run counter the objective of a balanced economic development in the entire area of the EU. For one thing this is because spatial development objectives are themselves prominent goals among the catalogue of objectives to be attained by transport policy. Particularly infrastructure investments which are co-financed by the structural funds, are regarded a means of regional policy supporting less favoured regions. Furthermore, transport policies motivated by efficiency or environmental reasons may have undesired regional side effects, that could generate political backlash, unless one offers some compensation. The spatial impact of the two named policies is studied with the help of a spatial computable general equilibrium model, called CGEurope. It is a static model with a large number of regions covering the whole area of the EU including the new member states, plus neighbouring countries, some of them also subdivided by regions. Regions interact by trade flows. Interregional trade is costly, with trade costs depending inter alia on the state of infrastructure and on gasoline prices and infrastructure charges. Transport policies are simulated by varying the costs of transport and quantifying the impact on the welfare of households brought about by changes in goods and factor prices. We develop a series of policy scenarios and evaluate their impact an spatial equality or inequality using a whole bundle of indicators of spatial inequality. The paper documents theses scenarios, explains the modelling framework in brief, discusses the inequality indicators to be used and maps and tabulates the main results.

Long-term response of corn to limited irrigation and crop rotations

Dwindling water supplies for irrigation are prompting alternative management choices by irrigators. Limited irrigation, where less water is applied than full crop demand, may be a viable approach. Application of limited irrigation to corn was examined in this research. Corn was grown in crop rotations with dryland, limited irrigation, or full irrigation management from 1985 to 1999. Crop rotations included corn following corn (continuous corn), corn following wheat, followed by soybean (wheat-corn-soybean), and corn following soybean (corn-soybean). Full irrigation was managed to meet crop evapotranspiration requirements (ETc). Limited irrigation was managed with a seasonal target of no more than 150 mm applied. Precipitation patterns influenced the outcomes of measured parameters. Dryland yields had the most variation, while fully irrigated yields varied the least. Limited irrigation yields were 80% to 90% of fully irrigated yields, but the limited irrigation plots received about half the applied water. Grain yields were significantly different among irrigation treatments. Yields were not significantly different among rotation treatments for all years and water treatments. For soil water parameters, more statistical differences were detected among the water management treatments than among the crop rotation treatments. Economic projections of these management practices showed that full irrigation produced the most income if water was available. Limited irrigation increased income significantly from dryland management

Creating Learning Environments More Supportive of Diversity: An Ongoing Working Group

At EDRA 31 in San Francisco we convened a working group to discuss issues related to creating learning environments more supportive of diversity. It has been five years since we last met. We believe it is time to revisit the issues of diversity in the leammg environment to see what gains we have made, if any, and what more we can do

Field scale limited irrigation scenarios for water policy strategies

ABSTRACT. Approaches to reducing irrigation inputs to crops have been studied for the past 50 to 60 years in research settings. Fewer efforts have been made to document limited irrigation responses over a number of seasons on commercial fields. This study compared farm−based irrigation management (FARM) with best management practices (BMP), late initiation of irrigation (LATE), and a restricted allocation (ALLOC). These irrigation management strategies each occupied 1/8 of a center pivot system in southwest Nebraska in continuous corn production, on four cooperating farms, which were replicated at the same sites for 3 to 6 years. Irrigation variables were achieved by irrigating or not irrigating, or by speeding up or slowing down the center pivot. When the grain yields and irrigation amounts were normalized each year using the FARM treatment as the basis, on average for three of four locations, the BMP treatment yielded equal to the FARM treatment, the LATE treatment yielded 93 % of the FARM treatment and the ALLOC yielded 84 % of the FARM treatment. At the same time, it took 76 % and 57 % of the water for the LATE and ALLOC treatments, respectively, to achieve these yields. The adjusted gross returns (yield price – irrigation treatment costs) of the irrigation treatments were analyzed for each location. When the gross returns were normalized using the FARM treatment as the basis, FARM and BMP returns were equal across combinations of high and low input commodity prices and pumping costs. The LATE treatment gross return was 95 % of FARM return. The gross return for the ALLOC treatment was 85 % to 91 % of the FARM treatment. The higher the water costs, the lower the difference between the highest and lowest returning water treatments. Relationships between evapotranspiratio
