Daily mean surface meteorology and river discharge in Central Sulawesi for the period 2002-2005

The El Niño/ Southern Oscillation (ENSO) phenomenon is the strongest known natural interannual climate fluctuation. The most recent two extreme ENSO events of 1982/83 and 1997/98 severley hit the socio-economy of main parts of Indonesia. As the climate variability is not homogeneous over the whole Archipelago of Indonesia, ENSO events cause negative precipitation anomalies of diverse magnitude and uration in different regions. Understanding the hydrology of humid tropical catchments is an essential prerequisite to investigate the impact of climate variability on the catchment hydrology. Together with the quantitative assessment of future water resource changes they are essential tools to develop mitigation strategies on a catchment scale. These results can be integrated into long term Integrated Water Resource Management (IWRM) strategies. The general objective of this study is to investigate and quantify the impact of ENSO caused climate variability on the water balance and the implications for water resources of a mesoscale tropical catchment.

Abundance and biomass of phytoplankton in the Black Sea near Gelendzhik in 2002-2005

It is shown that in 2002-2005 mass development of coccolithofore Emiliania huxleyi on the Gelendzhik shelf (northeast Black Sea) occurred annually and in May-June its abundance reached 1500000 cells/l. In 2004-2005 bloom of E. huxleyi was accompanied by mass development of diatom alga Chaetoceros subtilis var. abnormis f. simplex (600000-900000 cells/l). For the first time it was registered as a dominating form of Black Sea phytoplankton. Small flagellates and picoplankton algae played a noticeable role in phytoplankton throughout the entire period of the studies. Meanwhile in the early summer period the bulk of biomass consisted of coccolithophores (50-60%), while in the late summer period diatomaceous algae dominated (50-70%). Among ecological factors that favor coccolithophore development one may note microstratification of the upper mixed layer at a high illumination level and high temperature in surface waters (18-21°C). Terrigenous runoff during the rainy period had a negative effect on E. huxleyi development, while storms dispersed the population over the upper mixed layer. A wind-induced near-shore upwelling stimulated development of diatoms.

Barrio La Cecilia, Bogota, Colombia

El barrio de "La Cecilia" es un barrio ilegal por encontrarse en un terreno protegido, por lo tanto es necesario frenar la expansión y generar un nievo límite. En paralelo la ausencia de equipamientos y de espacio público, unido a un saneamiento sanitario existente precario hacen que no se cumplan los criterios de Habitabilidad Básica en el barrio. El proyecto que se propone plantea, aprovechando el plan de intervención en el espacio protegido de los Cerros Orientales, la creación de un nuevo parque lineal de acceso al río que genere un nuevo límite para evitar la expansión. El nuevo equipamiento estará relacionado directamente con las actividades del parque ya que será un reflejo de la percepción de los visitantes del reformado entorno natural. Por otro lado se plantea una nueva ordenanza que regule las futuras construcciones dentro del barrio y se propone una renovación del sistema de saneamiento urbano basado en un biosistema.

A youth vision of the city: The socio-spatial lives and exclusion of street girls in Bogota, Colombia

This dissertation documents the everyday lives and spaces of a population of youth typically constructed as out of place, and the broader urban context in which they are rendered as such. Thirty-three female and transgender street youth participated in the development of this youth-based participatory action research (YPAR) project utilizing geo-ethnographic methods, auto-photography, and archival research throughout a six-phase, eighteen-month research process in Bogotá, Colombia. ^ This dissertation details the participatory writing process that enabled the YPAR research team to destabilize dominant representations of both street girls and urban space and the participatory mapping process that enabled the development of a youth vision of the city through cartographic images. The maps display individual and aggregate spatial data indicating trends within and making comparisons between three subgroups of the research population according to nine spatial variables. These spatial data, coupled with photographic and ethnographic data, substantiate that street girls’ mobilities and activity spaces intersect with and are altered by state-sponsored urban renewal projects and paramilitary-led social cleansing killings, both efforts to clean up Bogotá by purging the city center of deviant populations and places. ^ Advancing an ethical approach to conducting research with excluded populations, this dissertation argues for the enactment of critical field praxis and care ethics within a YPAR framework to incorporate young people as principal research actors rather than merely voices represented in adultist academic discourse. Interjection of considerations of space, gender, and participation into the study of street youth produce new ways of envisioning the city and the role of young people in research. Instead of seeing the city from a panoptic view, Bogotá is revealed through the eyes of street youth who participated in the construction and feminist visualization of a new cartography and counter-map of the city grounded in embodied, situated praxis. This dissertation presents a socially responsible approach to conducting action-research with high-risk youth by documenting how street girls reclaim their right to the city on paper and in practice; through maps of their everyday exclusion in Bogotá followed by activism to fight against it.^
