Urban expansion and its impact on urban agriculture – remote sensing based change analysis of Kizinga and Mzinga Valley – Dar Es Salaam, Tanzania

Urban agriculture is a phenomenon that can be observed world-wide, particularly in cities of devel-oping countries. It is contributing significantly to food security and food safety and has sustained livelihood of the urban and peri-urban low income dwellers in developing countries for many years. Population increase due to rural-urban migration and natural, coupled with formal as well as infor-mal urbanization are competing with urban farming for available space and scarce water resources. A multitemporal multisensoral urban change analysis over the period of 25 years (1982-2007) was performed in order to measure and visualize the urban expansion along the Kizinga and Mzinga valley in the South of Dar es Salaam. Airphotos and VHR satellite data were analyzed by using a combination of a composition of anisotropic textural measures and spectral information. The study revealed that unplanned built-up area is expanding continuously and vegetation covers and agricultural lands decline at a fast rate. The validation showed that the overall classification accuracy varied depending on the database. The extracted built-up areas were used for visual in-terpretation mapping purposes and served as information source for another research project. The maps visualize an urban congestion and expansion of nearly 18% of the total analyzed area that had taken place in the Kizinga valley between 1982 and 2007. The same development can be ob-served in the less developed and more remote Mzinga valley between 1981 and 2002. Both areas underwent fast changes where land prices still tend to go up and an influx of people both from rural and urban areas continuously increase density with the consequence of increasing multiple land use interests.

Decision-Support tools for assessing land degradation and realising sustainable land management, Study Case of El Mkhachbiya Catchment, Northwest of Tunisia

Land degradation is intrinsically complex and involves decisions by many agencies and individuals, land degradation map- ping should be used as a learning tool through which managers, experts and stakeholders can re-examine their views within a wider semantic context. In this paper, we introduce an analytical framework for mapping land degradation, developed by World Overview for Conservation Approaches and technologies (WOCAT) programs, which aims to develop some thematic maps that serve as an useful tool and including effective information on land degradation and conservation status. Consequently, this methodology would provide an important background for decision-making in order to launch rehabilitation/remediation actions in high-priority intervention areas. As land degradation mapping is a problem-solving task that aims to provide clear information, this study entails the implementation of WOCAT mapping tool, which integrate a set of indicators to appraise the severity of land degradation across a representative watershed. So this work focuses on the use of the most relevant indicators for measuring impacts of different degradation processes in El Mkhachbiya catchment, situated in Northwest of Tunisia and those actions taken to deal with them based on the analysis of operating modes and issues of degradation in different land use systems. This study aims to provide a database for surveillance and monitoring of land degradation, in order to support stakeholders in making appropriate choices and judge guidelines and possible suitable recommendations to remedy the situation in order to promote sustainable development. The approach is illustrated through a case study of an urban watershed in Northwest of Tunisia. Results showed that the main land degradation drivers in the study area were related to natural processes, which were exacerbated by human activities. So the output of this analytical framework enabled a better communication of land degradation issues and concerns in a way relevant for policymakers.

Emerging Identities in Colonial Tunisia: "Alliancist" and Zionist Representations in Tunis prior to World War I

By 1900 the Jewish community of Tunisia witnessed the emergence of new competing identities: “assimilationist” of the Alliance Israelite Universelle, termed “Alliancist,” and Zionist. Strikingly, two members of the same family in Tunis, Raymond Valensi, President of the AIU Regional Committee, and Alfred Valensi, President of the Zionist Federation, led the struggle for their separate causes. In his discussion of identity in the modern world, Homi Bhabha asks, "How do strategies of representation or empowerment come to be formulated in the competing claims of communities…where, despite shared histories of …discrimination, the exchange of values, meanings and priorities…may be profoundly antagonistic…?" It is in this context that the claims of the Alliance and Zionism will be examined prior to World War I, based on the Archives of the AIU and on such secondary sources as the indispensable work of Paul Sebag. The tensions between the Alliancists and Zionists continued until the outbreak of World War II, as the French-speaking Jews of Tunisia sought to define their individual and collective identities.

Gender differences in life circumstances, monthly income, risky sexual and drug behaviors among injection drug users in Dar es Salaam, Tanzania

This study investigated the gender difference between male and female injection drug users’ (IDUs) life circumstances, income and risky sexual and drug behaviors. The study sample comprised of 318 male and 249 female injection drug users in Dar es Salaam, Tanzania. There were gender differences between male and female IDUs in terms of life circumstances and sexual behaviors. There were no differences in the drug behaviors among the two sexes. Women were more likely to be 21-25 years of age, have had more sexual partners in the last 30 days, traded sex for money, and have been sexually abused as a child. On the other hand, the males were more likely to be 26-30 years of age and have never used a condom during sex in the last 30 days. Regardless of the differences in sexual risk behaviors by gender, both male and female injection drug users in Dar es Salaam are at risk of HIV/AIDS, blood borne and other sexually transmitted diseases associated with drug use.^

STRATEGIES FOR THE TRANSFER OF APPROPRIATE TECHNOLOGY TO DEVELOPING COUNTRIES: THE IMPLEMENTATION AND DEVELOPMENT OF ENVIRONMENTAL HEALTH PROGRAMS IN TUNISIA

This dissertation focuses on Project HOPE, an American medical aid agency, and its work in Tunisia. More specifically this is a study of the implementation strategies of those HOPE sponsored projects and programs designed to solve the problems of high morbidity and infant mortality rates due to environmentally related diarrheal and enteric diseases. Several environmental health programs and projects developed in cooperation with Tunisian counterparts are described and analyzed. These include (1) a paramedical manpower training program; (2) a national hospital sanitation and infection control program; (3) a community sewage disposal project; (4) a well reconstruction project; and (5) a solid-waste disposal project for a hospital.^ After independence, Tunisia, like many developing countries, encountered several difficulties which hindered progress toward solving basic environmental health problems and prompted a request for aid. This study discusses the need for all who work in development programs to recognize and assess those difficulties or constraints which affect the program planning process, including those latent cultural and political constraints which not only exist within the host country but within the aid agency as well. For example, failure to recognize cultural differences may adversely affect the attitudes of the host staff towards their work and towards the aid agency and its task. These factors, therefore, play a significant role in influencing program development decisions and must be taken into account in order to maximize the probability of successful outcomes.^ In 1969 Project HOPE was asked by the Tunisian government to assist the Ministry of Health in solving its health manpower problems. HOPE responded with several programs, one of which concerned the training of public health nurses, sanitary technicians, and aids at Tunisia's school of public health in Nabeul. The outcome of that program as well as the strategies used in its development are analyzed. Also, certain questions are addressed such as, what should the indicators of success be, and when is the time right to phase out?^ Another HOPE program analyzed involved hospital sanitation and infection control. Certain generic aspects of basic hospital sanitation procedures were documented and presented in the form of a process model which was later used as a "microplan" in setting up similar programs in other Tunisian hospitals. In this study the details of the "microplan" are discussed. The development of a nation-wide program without any further need of external assistance illustrated the success of HOPE's implementation strategies.^ Finally, although it is known that the high incidence of enteric disease in developing countries is due to poor environmental sanitation and poor hygiene practices, efforts by aid agencies to correct these conditions have often resulted in failure. Project HOPE's strategy was to maximize limited resources by using a systems approach to program development and by becoming actively involved in the design and implementation of environmental health projects utilizing "appropriate" technology. Three innovative projects and their implementation strategies (including technical specifications) are described.^ It is advocated that if aid agencies are to make any progress in helping developing countries basic sanitation problems, they must take an interdisciplinary approach to progrm development and play an active role in helping counterparts seek and identify appropriate technologies which are socially and economically acceptable. ^

Investigating the epidemic of heroin use in Dar es Salaam, Tanzania: Recognizing the issues of heroin smokers

Since heroin was introduced to East Africa during the 1980s, heroin use practices have changed rapidly in response to various internal and external pressures. The aim of this study was to identify and describe the population of heroin users and locations of heroin use in Dar es Salaam, Tanzania, in order to understand recent contexts of heroin use. The study took place between June 30 and August 19, 2011, in all three districts (Kinondoni, Ilala, and Temeke) of Dar es Salaam. We mapped sites using a Global Positioning System device, counted numbers of heroin users, and conducted informal interviews with heroin users. The mixed-methods analyses of the data included quantifying the basic demographic and aggregate information about the sites and heroin users, as well as qualitative analysis and coding of fieldnotes from observations and responses to interviews which was used to identify themes and characteristics of heroin users. ^ We identified a total of 150 sites and counted a total of 1046 male and 46 female non-injecting drug users and 78 male and 9 female injecting drug users (IDUs) of heroin. We found that social organization existed at some of the sites, with 31% (n=47) of sites reporting having a leader and 44% (n=66) of sites reporting mutual aid between users frequenting the site. We had difficulty locating IDUs and female drug users, and the majority of users we encountered were heroin smokers of kokteli, a mixture of heroin, cannabis, and/or tobacco which is smoked like a cigarette. ^ This research highlighted heroin smokers’ desire for access to drug treatment services. The current methadone-based medication assisted treatment (MAT) program is funded and operates as an HIV prevention program for IDUs to reduce HIV infection in this population and slow or stop the spread of a second wave of HIV infection in the general population. However, smokers perceived MAT to be primarily a drug use prevention or cessation program and felt unjustly neglected from the intervention, leading to a tense relationship with IDUs. From a public health standpoint, future interventions should include heroin smokers to prevent HIV transmission. ^

La asunción de lo popular el teatro didáctico anarquista de Alberto Ghiraldo y su programa poético de «dar al pueblo la palabra»

Este trabajo aborda la conexión entre prácticas de comunicación y movimientos sociales a través de la particular asunción de lo popular que realizó el anarquismo en nuestro país a principios del siglo XX. Tomamos como caso particular el teatro didáctico propuesto por Alberto Ghiraldo, para describir algunas de las estrategias comunicacionales puestas en función, en relación con la cultura popular, con el fin de concientizar a las masas de los aspectos ideológicos del anarquismo.

Experiencia y experimentación : Apuntes sobre Me segura qu'éu vou dar um troço, de Waly Salomao

En 1972, en el marco de la dictadura que se lleva a cabo en Brasil, Waly Salomao publica Me segura que eu vou dar um troço, texto que comienza a escribir a modo de diario durante su estadía en la cárcel de Carandiru. Entablando un diálogo tanto con la tradición experimental de la Poesía Concreta como con la nueva sensibilidad que postula el Tropicalismo, Me segura que eu vou dar um troço se constituye como un ejercicio de experimentación formal que involucra tanto una dimensión ética como estética. El objetivo de nuestra exposición será, en este sentido, reflexionar acerca de la posibilidad de leer en el trabajo con las formas presente en Me segura que eu vou dar um troço una crítica a la ideología estética de la racionalidad moderna, en la medida en que pone en tela de juicio la pureza de lo estético y problematiza la relación entre la literatura y la vida

Visualidad y (meta)teatralización del poder en Darlo todo y no dar nada de Calderón

Mucho se ha escrito acerca de la fascinación de Calderón por la pintura, como lo prueban suDeposición en defensa de aquel arte y de sus hacedores, las tramoyas y grandiosas escenografías en los montajes de su teatro palaciego y la incorporación de diversas técnicas de visualización pictórica en la escritura de sus comedias, tal como sucede en Darlo todo y no dar nada (1651). Los cuatro retratos materialmente existentes en su realización escénicainvolucran a Alejandro Magno, Apeles y Campaspe y comprometen la decisiva intervención del filósofo Diógenes, contrafigura del Príncipe. Pero los retratos -más allá de su funciónexplícita en la trama de la comedia- se erigen en claves visualizadoras de las antinomiasrealidad/artificio, verdad/ trampantojo. Estos espejos abreviados del sentido profundo de la comedia, simultáneamente refieren elípticamente al presente histórico del lector/espectadordel Seiscientos y expresan una tendencia innovadora dentro del espectro metateatral barroco. La pintura en el teatro, axis de la comedia, puede ser espejo que duplica el ser o cristalengañosamente transparente, político, cuando el retratado es Alejandro, cuyo poderío convierte al mundo en "línea de su imperio". Parafraseando a Diógenes, deus ex machina ydoble del dramaturgo, es forzoso que la ciencia, "contra los achaques del siglo" acuda al artificio del artificio teatral, esto es, al metateatro, para desenmascarar la paradojal trama del poder imperial de Felipe IV.

"No le vamos a dar voz a los represores" : (Des)autorizaciones y (des)legitimaciones en las audiencias del juicio a Etchecolatz

En 2006 se desarrolló en La Plata un juicio a quien fuera Director General de Investigaciones de la policía de la provincia de Buenos Aires durante la última dictadura, Miguel Etchecolatz. Acusado en esta oportunidad por ocho casos de privaciones ilegales de la libertad, aplicación de tormentos y homicidios, fue condenado a reclusión perpetua. Se trató del primer juicio realizado a partir de la anulación de las leyes de Punto Final y Obediencia Debida y, a diferencia de los procesos judiciales realizados durante la década del ochenta, contó con la figura de querellantes. Así, junto a la fiscalía de Estado participaron de la acusación personas particulares, organismos de derechos humanos y diversas organizaciones sociales. En este trabajo nos proponemos analizar las diferentes estrategias jurídico-políticas que adoptaron los distintos actores sociales durante la etapa de audiencias testimoniales del juicio oral, como parte de las luchas por los sentidos del pasado
