5. Self-Reported Job Stress and Personality in Teachers of Students with Emotional or Behavioral Disorders.

Author

Center, David B. and Callaway, John M.

Abstract

A study of 149 teachers of students with emotional/behavioral disorders (E/BD) found that the higher the teacher's susceptibility to occupational stressors, the more willing the teacher was to leave the E/BD teaching field. Only 3 of the top 10 stressors were student-related. Results found an injury rate of one in five. (CR)

Abstract

Planting trees to sequester carbon has broad political appeal. However, effects of a major tree planting program on the agricultural sector and on timber markets are unclear. This paper examines social costs of sequestering carbon in tree plantations on U.S. agricultural land and investigates harvesting's effects on timber prices and on private timber producers' welfare. The analysis links a model of the U.S. agricultural sector that includes the land base in major production areas with a model of the U.S. softwood economy. Using current data on planting, maintenance, and harvesting costs for tree plantations and carbon sequestration rates, the models estimate the price and welfare effects of alternative carbon sequestration goals. Results indicate a range of outcomes. Consumers pay higher prices for food as farmers divert land from crops to trees. However, wood products consumers gain from falling timber prices if the trees enter commercial markets. Agricultural producers and landowners gain from higher commodity prices, but private forest owners lose. Large tree planting programs imply that policymakers must compensate private commercial tree planting to prevent farmers from displacing present tree plantations.

Abstract

The broad objective of AIACC project 47 was to develop the capacity to estimate and compare the benefits and costs of projects in natural resource sectors that reduce the expected damages from climate change in Southern and West Africa. There are two parts to this project. The first consists of using well-established principles from economic benefit-cost analysis to develop a framework to estimate the economic benefits and costs associated with the expected climate change damages avoided by a development project that does not take climate change into account. Then, these benefits and costs can be compared to the case where planners incorporate expected climate change into the project assessment. The second part consists of demonstrating this methodology in two project case studies, one in The Gambia and the other in South Africa. The South African case study examines the benefits and costs of avoiding climate change damages through structural and institutional options for increasing water supply in the Berg River Basin in the Western Cape Province. The Gambian study, on the other hand, focuses on the agricultural sector, particularly on millet, the predominant crop in the country. To facilitate analysis, the Gambian study uses a detailed water–crop model, defines and explores adaptation strategies with the model and uses the results to carry out an economic analysis. The South African project develops and applies a Berg River Dynamic Spatial Equilibrium Model as a water planning and policy evaluation tool to compare benefits and costs and economic impacts of alternatives for coping with longterm water shortages due to climatic change. Results from the study will contribute to the development of international climate change policies and programs, particularly in regard to adaptation activities in developing countries under the United Nations Framework Convention on Climate Change (UNFCCC).

Abstract

Chapter 7 of the book "Climate Change and Adaptation" is presented. It highlights the use of the SWAP-WOSOFT model in combination with CEREAL to investigate the impact of climate change on the cereal balance under different management options in Gambia. It aims to look into the economic efficiency of specific management options that are subject to social and political acceptability.

Abstract

Chapter 3 of the book "Climate Change and Adaptation" is presented. It explores the elements in the analysis of water planning and management at Berg river, in Western Cape Region of South Africa. It examines the development of policy-planning model that can be used to evaluate a wide range of structural, non-structural and technological measures for coping with basin water shortages due to demand growth, climate variability and climate change.
