Survival in the Sahel an Ecological and Developmental Challenge Survival in the Sahel An ecological and developmental challenge Edited by Klaus M. Leisinger and Karin Schmitt and the International Service for National Agricultural Research (ISNAR) Ai-n " islnur The mandate of the International Service for National Agricultural Research (ISNAR) is to assist developing countries in bringing about lasting improvements in the performance of their national agricultural research systems and organizations. It does this by promoting appropriate agricultural research policies, sustainable research institutions. and improved research management. ISNAR's services to national research are ultimately intended to benefit producers and consumers it developing countries and to safeguard the natural environment for future generations. ISNAR offers developing countries three tynes of service, supported by research and training: " For a limited number of countries, ISNAR establishes long-term, comprehensive partnerships to support the development of sustainable national agricultural research systems and institutions. * For a wider range of Lountries. ISNAR gives support for strengthening specific policy and nmanagement components within the research system or constikdent entities. * For all developing countries, as well as the international development community and othcr interested parties. ISNAR disseminates knowledge and information about national agricultural research. ISNAR was established in 1979 by the Consultative Group on International Agricultural Research (CGIAR), on tie basis of recominendations from an international task force. It began operating at its headquarters in The II ague, [he Netherlands. on September I, 1980. ISNAR is a nonprofit. autonoous institute, international in character and apolitical in its illluingelinent. stal fing. and operations. It is financially supported by a [umber of the menbers ot the CGIAR, an informal group of donors thait includes countries, development banks, international organi/ations, and foundations. Of the 16 centers in the CGIAR system of interiiational centers, ISNAR is the only one that focuses specifically on instiltitional development within national agricultural research systems. The CIBA-GEIGY Foundation for Caoperation with Developing Countries was established in 1979 to channel and strengthen the efforts ofthe CIBA-GEIGY corporation ir: humanitarian assistance and to consult CIBA-GEIGY management on sustainable development issues. The Foundation's charity activities focus on the poorest segments of the population in dCveloping countries and include leprosy control and rehabilitation projects, agricultural rea:arch anild sustainable ari cultural devclopment projects, as well as gender-orie nted social developnent projects in Asia, Africa, and Latin A merica. To he able to deliver up-to-date consulting on development issues, the Foundation has established a development policy data base, does its own research on issues of sustainable development, and regularly takes part in developmient dialogues with nongovernmental organizations (NGOs). international organizations, and scientific institutions. The CIBA-GEIGY Foundation operates independ, Jy from the CIBA-GEIGY commercial enterprise. Survival in the Sahel An ecologicaland developmental challenge Edited by Klaus M.

The case of the Sahel, plagued by civil strife, poverty, and hunger and natural calamities such as deser­ tification and droughts, has become a major challenge facing humankind today. The environment and the living conditions have continued to deteriorate in spite of heavy investments, in­ numerable plans of action, and new organizations and institu­ tions-a baffling puzzle, considering that worldwide our genera­ tion has experienced more technoiogicaJ breakthroughs than ever before. It may seem to those interested in the development of the Sahel that there has been only bad news about the region over the past two decades. This has led some to believe that there have been no success stories. Obviously, in spite of the overall gloomy picture, there have been successes. The question is why these cases, rare though they may be, have not been reported and shared among the African countries and the international com­ munity. Today's situation, the result of a combination of human behavior, poverty, illiteracy, rapid growth in populations,

  • Decomposing Gender and Ethnic Earnings Gaps in Seven West African Cities

Analysing gender and ethnic earnings gaps in an African context raises a number of important issues that our paper attempts to address, notably by taking into account labour allocation between public, private formal and informal sectors which can be expected to contribute to earnings gaps. Our results show that gender earnings gaps are large in all the cities of our sample and that gender differences in the distribution of characteristics usually explain less than half of the raw gender gap. By contrast, majority ethnic groups do not appear to have a systematic favourable position in the urban labour markets of our sample of countries and observed ethnic gaps are small relative to gender gaps.

  • Analysis of `Miholjday Summer' for Belgrade and Serbia Region
    INTERNATIONAL JOURNAL OF CLIMATOLOGY Int. J. Climatol. 26: 1489–1499 (2006) Published online in Wiley InterScience (www.interscience.wiley.com) DOI: 10.1002/joc.1390 ANALYSIS OF ‘MIHOLJDAY SUMMER’ FOR BELGRADE AND SERBIA REGION NEDELJKO TODOROVIC´ a* and DRAGANA VUJOVIC´ b* a Hydrometeorological Service of Serbia, Belgrade, Yugoslavia b Department of Meteorology, Faculty of Physics, Belgrade, Yugoslavia Received 30 May 2006 Revised 14 February 2006 Accepted 11 April 2006 ABSTRACT Typical weather conditions with dry and warm features occur in autumn months, with temperatures above the normal temperatures for this period of the year for the Belgrade and Serbia region. Temperatures have values like the ones for the end of summer. That period of fair weather is called Miholjday (St Michael) summer (MS). An analysis of temperature has been the most important criterion for defining MS. Synoptic situation and temperature conditions during that period are analyzed and typical and atypical MSs are defined for Belgrade and Serbia region. The frequency of MS in the period 1946–2004 for Belgrade region is also analyzed. The general definition (Glossary of Meteorology) is assumed and we gave the specific definition of MS for Belgrade and Serbia region on the basis of real weather for longer series of observations. Copyright 2006 Royal Meteorological Society. KEY WORDS: summer climate variability; weather singularity; weather classification; synoptic climatology 1. INTRODUCTION Miholjday summer (MS) appears in autumn, in the period from the middle of September to the beginning of November. The name is related with Miholjday, the Christian feast celebrated on 12 October in the Orthodox Church (29 September in the Catholic Church).

GLOSSARY Chapter 1 Aerosols Tiny suspended solid particles (dust, smoke, etc.) or liquid droplets that enter the atmosphere from either natural or human (anthropogenic) sources, such as the burning of fossil fuels. Sulfur-containing fossil fuels, such as coal, produce sulfate aerosols. Air density The ratio of the mass of a substance to the volume occupied by it. Air density is usually expressed as g/cm3 or kg/m3. Also See Density. Air pressure The pressure exerted by the mass of air above a given point, usually expressed in millibars (mb), inches of (atmospheric mercury (Hg) or in hectopascals (hPa). pressure) Atmosphere The envelope of gases that surround a planet and are held to it by the planet's gravitational attraction. The earth's atmosphere is mainly nitrogen and oxygen. Carbon dioxide (CO2) A colorless, odorless gas whose concentration is about 0.039 percent (390 ppm) in a volume of air near sea level. It is a selective absorber of infrared radiation and, consequently, it is important in the earth's atmospheric greenhouse effect. Solid CO2 is called dry ice. Climate The accumulation of daily and seasonal weather events over a long period of time. Front The transition zone between two distinct air masses. Hurricane A tropical cyclone having winds in excess of 64 knots (74 mi/hr).

Another purpose of the study to identify the duration of demands for the particular design/style. Thus the market value automatically high during the trend season and the merchandising process would across the break even point. Keywords : Color, Material, Market, Season, Stipulation. I. Introduction It's time to wrap up warm for autumn and winter, but there's no need to stop looking fabulous. Fashion trends this winter will let you retain a bit of glam - while also staying warm - and with versatility there's something to suit all styles and body shapes. Fashion trends change frequently keeping retail professionals on their toes. One of the most anticipated fashion trends involves the most popular colors which shift from season to season. Each year Pantone announces its top color often inspiring clothing and accessory designs for winter season, Pantone's top color is emerald green, and the color showed up consistently on the fall and winter runway shows indicating that it will be a mainstay of winter fashion. “During the cold and dark of Arctic winter, sea ice refreezes and achieves its maximum extent, usually in late Feb. or early Mar. According to a NASA analysis, this year the annual maximum extent was reached on Feb.

    INFORMATION TO USERS This material was produced from a microfilm copy of the original document. While the most advanced technological means to photograph and reproduce this document have been used, the quality is heavily dependent upon the quality of the original submitted. The following explanation of techniques is provided to help you understand markings or patterns which may appear on this reproduction. 1. The sign or "target" for pages apparently lacking from the document photographed is "Missing Page(s)". If it was possible to obtain the missing page(s) or section, they are spliced into the film along with adjacent pages. This may have necessitated cutting thru an image and duplicating adjacent pages to insure you complete continuity. 2. When an image on the film is obliterated with a large round black mark, it is an indication that the photographer suspected that the copy may have moved during exposure and thus cause a blurred image. You will find a good image of the page in the adjacent frame. 3. When a map, drawing or chart, etc., was part of the material being photographed the photographer followed a definite method in "sectioning" the material. It is customary to begin photoing at the upper left hand corner of a large sheet and to continue photoing from left to right in equal sections with a small overlap. If necessary, sectioning is continued again — beginning below the first row and continuing on until complete. 4. The majority of users indicate that the textual content is of greatest value, however, a somewhat higher quality reproduction could be made from "photographs" if essential to the understanding of the dissertation.

  • Sub-Saharian Immigration in France : from Diversity to Integration
    Sub-Saharian immigration in France : from diversity to integration. Caroline JUILLARD Université René Descartes-Paris V The great majority of Sub-Saharian African migration comes from West - Africa, more precisely from francophone countries as Senegal, Mali, and into a lesser extent Guinea, Guinea-Bissau, Mauritania. There are also migrants from other francophone African countries such as : Zaïre (RDC), Cameroon, Ivory Coast, Niger. Migrants consist mostly of workers and students. I shall speak principally of West-African migration for which sociolinguistic sources are not many. My talk will have three main parts. I General characteristics of this migration. A/ Census data First of all, I will discuss census data. The major trend of immigration to France nowadays comes from Sub-Saharian Africa ; it has tripled between 1982 et 1990 and almost doubled according to the last census of 1999 (Cf. Annexes). According to 1999 census, this migrant population counts more or less 400.000 persons. Official data are multiple and differ from one source to the other. Variations are important. Children born in France from immigrant parents do not participate to the immigrant population and, so for, are not included in the migration population recorded by the national census. They are recorded by the national education services. Moreover, there might be more persons without residency permit within the Sub-Saharian migration than within other migrant communities. I 2 mention here well-known case of “les sans-papiers”, people without residency permit, who recently asked for their integration to France. Case of clandestines has to be mentioned too. Data of INSEE1 do not take into account these people.
