The conventional discourse relating climate change to conflict focuses on long term trends in temperature and precipitation that define ecosystems and their subsequent impact on access to renewable resources. Because these changes occur over long time periods they may not capture the proximate factors that trigger conflict. We estimate the impact of both long term trends in climate and short term climatic triggers on civil conflict onset in Sub-Saharan Africa. We find that both...

This study aimes at investigating the level of practice of supervisory competences for the secondary school principals in the light of the variables of: (gender, scientific qualifications, experience, and the directory) from the teachers' perspectives in the northern Governates of Palestine. The study's sample consisted of (250) teachers, selected randomly to represent (5%) of the study population (3913) teachers in the scholastic year 2005/2006. To accomplish the study's objectives, the...

To determine if short-term nutrition education can increase calcium intake or breakfast consumption in African American College Students

Under Ottoman rule, the relations between native Arabs and Jews in Palestine were based on understanding and respect, as was the case between Muslims and Christians. Shared enrolment of Jewish, Muslim, and Christian students in the same schools—either the Jewish Alliance Israelite schools (established in 1882) or in the nizamiyya , the Ottoman public schools first established by the Turkish law of 1869—promoted mutual understanding for a small elite. In contrast, the British Mandate policy...

Abstract A recent study carried out by European and African organizations into the potential for electronic distance training (EDT) on sustainability in African local governments concluded that EDT was both ‘useful and feasible’. This article reflects on some of the theoretical and practical implications of that study. It focuses on the connection between learning and sustainability and how EDT programmes might be designed and promoted. The paper argues that, while resource issues and poor...

In the decades following World War II, access to higher education became an important vehicle for expanding opportunity in the United States. The African American-led Civil Rights Movement challenged discrimination in higher education at a time when state and federal government leaders saw strengthening public higher education as necessary for future economic growth and development. Nationally, the 1947 President's Commission on Higher Education report Higher Education for American Democracy...

This paper measures the economic impact of climate on crops in Kenya. The analysis is based on cross-sectional climate, hydrological, soil, and household level data for a sample of 816 households, and uses a seasonal Ricardian model. Estimated marginal impacts of climate variables suggest that global warming is harmful for agricultural productivity and that changes in temperature are much more important than changes in precipitation. This result is confirmed by the predicted impact of...

No studies have addressed the spatial complexity of Anopheles arabiensis populations in Zambia or the effects of drought on the genetic structure of this species. We genotyped approximately 420 An. arabiensis at 12 microsatellite loci representing 18 collections from the Southern Province of Zambia. Collections spanned three transmission seasons and covered a wet year-drought year-wet year cycle. Anopheles arabiensis within the 2,000 km(2) of the Macha study region were panmictic, with high...

This study examines the impact of climate change on cropland in Africa. It is based on a survey of more than 9,000 farmers in 11 countries: Burkina Faso, Cameroon, Egypt, Ethiopia, Ghana, Kenya, Niger, Senegal, South Africa, Zambia, and Zimbabwe. The study uses a Ricardian cross-sectional approach in which net revenue is regressed on climate, water flow, soil, and economic variables. The results show that net revenues fall as precipitation falls or as temperatures warm across all the...

The objective of this paper is to determine the ability of farmers in Africa to detect climate change, and to ascertain how they have adapted to whatever climate change they believe has occurred. The paper also asks farmers whether they perceive any barriers to adaptation and attempts to determine the characteristics of those farmers who, despite claiming to have witnessed climate change, have not yet responded to it. The study is based on a large-scale survey of agriculturalists in 11...

This paper uses the Ricardian approach to examine how farmers in 11 countries in Africa have adapted to existing climatic conditions. It then estimates the effects of predicted changes in climate while accounting for whatever farmer adaptation might occur. This study differs from earlier ones by using farmers'own perceptions of the value of their land. Previous research, by contrast, has relied on either observed sale prices or net revenues, sometimes aggregated over geographically large...
