Evaluation: an opportunity for improvement
No full textThis chapter addresses the theme of project evaluation. What is the evaluation, when it is performed and what is its purpose? The chapter advances the idea that it is time to stop seeing the evaluation as a mere judgement, and to ponder the true meaning of the evaluation which is: "giving value" to the project. The evaluation is the process recognizing the social value created in the community by the project as external development intervention. The chapter aimed at guiding development actors to "receiving" and evaluation and draw recommendations to improve future interventions
Implementing the Project
No full textImplementing a project requires multiple skills and a strong leadership, capable of providing the team with the proper indications, foreseeing risks, monitoring the development of the activities and maintaining a constructive relationship with the beneficiaries of the project activities and with the donor. This chapter guides migrants' associations towards the project implementation, starting from the leadership and from the composition of the work team, and ending with the project closure
La coopération décentralisée et la gouvernance locale: Analyse comparative au Burkina et au Sénégal
No full textCette étude a pour objectif de faire une analise comparé des parcours de décentralisation administrative en
Sénégal et en Burkina Faso, en mettant en évidence l'aspect de planification territoriale au niveau régional, la concertation et la participation des
collectivités aux processus de développement local. L'étude présente une réflexion sur le rôle que la coopération décentralisée peut jouer en appuiaux processus de décentralisation pour
promouvoir une véritable participation de tous les
acteurs sur la voie du développement local. La
méthodologie de recherche a été basée sur la
participation à l'étude d’«experts» de nationalité
sénégalaise et burkinabè qui ont offert leurs
connaissances du territoire et des processus
politiques en acte, permettant ainsi de tracer un
cadre du parcours institutionnel suivi par le pays dans le domaine de la décentralisation et de la
planification locale
Implications of prolonged ice coverage in the Ross Ssea, (Antarctica) on phytoplankton assemblages

No full textPrimary production processes and photosynthetic performance of a unique periantarctic ecosystem: the Strait of Magellan
No full textDuring the late austral summer and early autumn 1995 (March–April), an oceanographic cruise was conducted along the Strait of Magellan in order to study the photosynthetic performance of phytoplankton assemblages.
The high correlations between the pico–nano fractions and
both the total biomass concentrations (Chla) and primary
production rates emphasized the role of these fractions
in driving the primary production processes. Repeated
P versus E experiments were conducted in the most productive
area of the Strait, Paso Ancho, in order to assess the
influence of the tidal currents on phytoplankton photosynthetic
performance. These data were compared to those
available from a previous cruise (February–March, 1991)
carried out along the Strait. In the Pacific–Andean sector,
the primary production processes were highly controlled by
wind, land forcing, and irradiance availability. In the Paso
Ancho, the observed highest photosynthetic capacity PBm (up to 6.5 mgC mgChla-1 h-1) and the high primary production rates may due to the continuous mixing of the water column forced by the strong tidal currents within the photic layer. The non-limiting, macro-nutrient concentrations in the Strait indicate that the available irradiance and the depth of mixed layer are the main driving factors of the primary production processes. The photosynthetic performance of the phytoplankton assemblages renders the Strait a unique ecosystem, which is more similar to those of the mid-latitudes than to those of the periantarctic areas
Produzione Primaria
No full textIl metodo per la determinazione della produzione primaria fitoplanctonica consiste nell’incubare dei campioni di acqua di mare in due bottiglie chiare ed una scura in cui viene inoculata una quantità nota di soluzione radioattiva (NaH14CO3). Le due bottiglie chiare servono a mediare le eventuali differenze dovute alla non omogeneità del campione e danno, come risultato, la misura della produzione primaria. La bottiglia scura permette di stimare valori di 14C organico di “background” e l’eventuale fissazione di C che può avvenire al buio, principalmente per cause fisiche e chimiche.
Il metodo si basa sull’assunto che l’assimilazione del 14C-DIC è proporzionale a quella del 12C-DIC, tenendo conto di un fattore di correzione che compensi la differente velocità di assimilazione della 14C rispetto al 12C

No full textTROPHIC CHARACTERIZATION OF THE PELAGIC ECOSYSTEM IN VLORA BAY (ALBANIA)
No full textPhytoplankton assemblages were studied to characterize the trophic status of the semienclosed Vlora Bay (Albania) and to evaluate the influence of terrestrial inputs on its pelagic ecosystem. The study was carried out as part of the European Project CISM (INTERREG IIIA Italy–Albania) and conducted during two oceanographic cruises (spring 2007, winter 2008). The size-fractionated chlorophyll a concentrations, primary production rates, and the chemotaxonomic composition (high-performance liquid chromatography) of the phytoplankton assemblages were measured. The spatial variability of primary production rates and chlorophyll a concentrations both showed a pronounced E-W gradient in the surface layer, with the highest values along the eastern coast. In spring, a deep chlorophyll maximum was observed in the central western part of the bay, whereas in winter a homogeneous vertical distribution was observed. The phytoplankton assemblages were quite similar in both seasons and were dominated by the picophytoplankton fraction (<46% and 53% in spring and in winter, respectively). Haptophytes and pelagophytes were the major phytoplankton groups, and accounted, respectively, for 50% and 15% in spring, and 40% and 25% in winter. The results showed that Vlora Bay was characterized by generally oligotrophic conditions and that the influence of the southern Adriatic open waters was negligible. The trophic characteristics of the pelagic ecosystem of the bay were essentially driven by terrestrial inputs
