Full textThe work described in this manuscript concerns four sponges from the South-West Indian Ocean: Plakortis kenyensis, Theonella swinhoei, Haliclona fascigera and Fascaplysinopsis reticulata. The chemical study of the sponges including extraction, isolation and identification of secondary metabolites was undertaken using various chromatographic (MPLC, HPLC ...) and spectroscopic (UV-visible, HRMS, 1D and 2D NMR ...) techniques. Twelve secondary metabolites including six new molecules were isolated from these sponges. The new molecules are: 2,5-époxydocosan-6-en-21-ynoic acid (HF1) an unusual fatty acid isolated from the sponge Haliclona fascigera; 8-oxo-tryptamine (FR2), 6,6'-bis (debromo)-gelliusine F (FR3), 6-bromo-2'-demethyl-3'-N- methyl-1',8-dihydroaplysinopsine (FR6), 5,6-dibromo-2'-demethyl-3'-N-methyl-1',8-dihydroaplysinopsine (FR7) and 5,6-dibromo-3’-deimino-2’-demethyl-3’-oxo-1’,8-dihydroaplysinopsine (FR8), five indole alkaloids isolated from the sponge Fascaplysinopsis reticulata. The biological activities of the isolated molecules were then evaluated. Among the twelve isolated molecules, seven were active against the malaria parasite Plasmodium falciparum, three were identified as inhibitors of the quorum sensing-regulated bioluminescence in Vibrio harveyi and five, showing marine bacterial adhesion and/or growth inhibition, exhibited potential anti- microfouling activity

Full textThe main purpose of this interdisciplinary thesis was to study Biemna laboutei, a sponge from Madagascar, known to have toxic properties (dermatitis-producing). The chemical investigation of this sponge including extraction, isolation and identification of secondary metabolites was first undertaken using several chromatographic (HPLC, MPLC…) and spectroscopic (UV-visible, HRMS, NMR 1D et 2D…) techniques. Eighteen alkaloids belonging to the rare class of tricyclic (5,6,8b)-triazaperhydroacenaphtylene heterocycles (i.e. ptilocaulins, mirabilins, netamines) were isolated and identified. Twelve new alkaloids from this group of guanidine derivatives were named netamine H-S. These compounds were grouped on the basis of unsaturation and double bond regiochemistry, with pyrimidine, Δ8,8a and Δ8a,8b heterocycles. For two compounds, netamine I (58) and J (59), a joint theoretical (Density functional theory) and experimental study of UV and ECD spectra allowed the determination of their absolute configuration: 5aS, 7R, 8R for netamine I and 5aS, 7R, 8S for netamine J. The chemotaxonomic meaning of these alkaloids was discussed. Their biological activities were also evaluated. Netamine M (62) exhibited a cytotoxic activity towards KB cells (IC50 = 1,0 μg/mL) while netamine O (64), Q (66) and K (60) were active against the malaria parasite Plasmodium falciparum with IC50 value of 4,66; 2,53 and 0,62 μg/mL respectively. Finally, this work was also dedicated to the biomimetic synthesis of the tricyclic guanidine skeleton. Three new synthesis routes were explored

Full textThe diversity of cropping systems and varieties plays an important role in the ability of family farms to withstand socio-economic and environmental shocks. For better conservation, this agricultural diversity needs to be characterized and monitored in space and time. While they were dominated by elements of price, area and production until recently, agricultural monitoring systems are beginning to integrate diversity issues. The diversity of cropping systems and varieties plays an important role in the ability of family farms to resist socio-economic and environmental shocks, whereas until the end of the 1990s it was considered as a limiting factor in improving the productivity of farming systems in varietal selection processes. In a situation of uncertain rainfall, to reduce the risk of this hazard, farmers use several species and varieties to survive and produce through all the hazards encountered. The peasant strategy consists in cultivating several varieties with different agronomic characteristics (early maturity, yield, resistance to diseases, parasites and drought, etc.) and culinary in the same field or in different fields. This strategy allows farmers to cultivate the varieties best suited to the soil conditions of their fields and to meet their diverse needs.It is in this context that this thesis focuses on the spatial structuring of agrobiodiversity in the cotton zone. To achieve this objective, several methods and approaches have been used. The approach adopted combines the digital analysis of satellite imagery and the use of data from field surveys. The analysis of these data is based on the spatial distribution of biodiversity and its correlation with agro-ecological practices and conditions, agronomic performance and performance.The main results from the analysis of the study data are:a) There is a great heterogeneity and diversity of landscapes in the cotton zone of Mali-Sud with a total of eleven (11) landscape units;b) There is great diversity at the specific level and in cropping systems. The mean values of the most specific indicator of diversity are recorded in villages where the mean rainfall is between 700 and 1000 mm of water followed by villages of less than 700 mm;c) The specific pressure indicator shows a geographical distribution of the pressures of the different crop species. Indeed, in villages where cotton is at the head of rotation, it exerts strong pressure on other species. In these villages, the cotton area is much larger than for the other species;d) For yield, most villages have average yields of cotton above the national average in 2015. Analyzing its evolution between 2013 and 2015, there is a decline in yield in most villages if this decline is very often sawtooth with increases in 2013 and 2014.e) The yield stability indicator shows that yields are stable with all species except maize.These results open the way for a greater contribution of geography in agronomic analysis

Full textThe Owen Fracture Zone (OFZ) is a 800 km-long fault system that currently accommodates the dextral strike-slip motion between India and Arabia plates. It closely follows a small circle about a rotation pole determined with GPS and seismicity data, which is consistent with a pure strike-slip motion along the entire fracture zone. As shown by the high resolution multibeam bathymetric map with full coverage (OWEN-1 cruise), it is made up of a series of fault segments separated by releasing and restraining bends, including a major pull-apart basin at latitude 20°N and two stepover basins at its terminations, the Beautemps-Beaupré Basin to the south and the Dalrymple Trough to the north. The OFZ crosscuts the Owen-Murray Ridge, a series of prominent oceanic highs. Offsets of the Owen Ridge observed on the seafloor indicate a finite dextral displacement of 10-12 km along the OFZ. Considering a steady motion of 3 ±1 mm. Y-1 estimated independently from geodetic and geological data, this implies that the present-day trace of the OFZ has been active since at least 3 to 6 Ma. Consistently, the age of opening of the 20°N Basin and the Dalrymple trough is estimated at about 2-3 Ma ago by calibration with DSDP-ODP drillings, coevally with a regional unconformity over the Oman abyssal plain (the M-unconformity). The Owen-Murray Ridge is dissected by complex systems of submarine landslides, which may represent a source of tsunami hazard for the nearby Oman coast according to numerical models. Stratigraphic studies document a recurrence in the order of 105-106 yrs, indicating that such tsunamis are infrequent. The seismic dataset collected during the Owen-2 cruise provides the first identification of the Miocene and Paleogene traces of the plate boundary prior to the activation of the OFZ, and leads to a full revision of the geological history of the area. We highlight the composite age of the Owen Basin basement, made of Paleocene crust drilled on its eastern part, and composed of pre-Maastrichtian crust overlain by Upper Cretaceous ophiolites on its western side (at the edge of the Oman Margin). A major transform fault crossing the Owen Basin juxtaposed these two slivers of lithosphere of different ages. This transform system used to be associated with the Carlsberg spreading center during the Paleogene, which formed most of the Owen Basin basement. The inactivation of the transform system in Late Eocene-Early Oligocene times is marked by the uplift of marginal ridges along the Oman Margin and a regional angular unconformity. The transform system then shifted to a narrow structure located at the edge of the present-day Owen Ridge in Late Oligocene times, shortly before seafloor spreading began at the Sheba Ridge. This migration of the plate boundary involved the capture of a part of the Indian oceanic lithosphere accreted at the Carlsberg Ridge (in Paleocene-Eocene times) to the Arabian plate. The Owen Ridge uplifted much latter, in Late Miocene times (8. 2-8. 8 Ma), in response to a kinematic change of the Indian plate. This episode of deformation ultimately led to the inactivation of the Miocene plate boundary and the activation of the OFZ. A major environmental change is recorded over the Arabian Sea coasts in the Siwalik paleosol sequence, coevally with this episode of deformation. This environmental change was previously interpreted as the result of an intensification of the Indian Monsoon at ~8. 5 Ma recorded by a drastic increase in G. Bulloides abundance in the sedimentary cover of the Owen Ridge. In contrast, we propose that the uplift of the Owen Ridge 8-9 Ma ago induced better preservation of foraminifers. Furthermore, this episode of deformation could have also triggered continental uplift along the East Oman and the Dhofar margin, and at the Makran accretionary wedge, leading to a reorganization of the atmospheric circulation that could explain the coeval environmental change recorded in the Siwalik sequence in Pakistan

Full textThis research is based upon a fieldwork amongst young people in marginalized urban areas in Guadeloupe. Inheriting the political history of slavery, colonization and subsequent dependency, whilst also confronted with stigmatization, violence, unemployment, aimlessness, drugs and poverty, these young people have, nonetheless, established their own culture. In this thesis, I study the conceptions they have about power and politics in an oppressive social context, to understand how daily practices of rebellion and transgression link up with a desertion of politics while preventing any collective action able to question the power relationships in Guadeloupe. Due to the desertion of politics, these conceptions reveal themselves in the culture of young people living in marginalized urban areas. Subsequently, this thesis is an exploration of the daily lives of these young people: street life, dance, music, informal economy, sexuality and violence. The culture of young people in marginalized urban areas is influenced by two dynamics: marginality and the search for power. Marginality comes up from a complex relationship with Guadeloupean society, characterized by transgression, avoidance and interdependence. The search for power is both a way to interact with others and a principle structuring the world representation that young people use to understand the contemporary era and to create compensating values. Marginality and Power are two dynamics that proceed according to hubris: a refusal of one's own weakness which is expressed by a violent passion for excessiveness and outrageousness. In marginalized urban areas, hubris refers to the refusal of both poverty and the inheritance of slavery

Full textThe Hindu-Kush Karakoram Himalayan (HKH) region is the largest snow and ice reservoir on the planet outside the Polar Regions. In the HKH region the mass balance and meteorological observations are sparse and the historical knowledge is mainly concentrated on snout fluctuation records. Hitherto, the understanding of glacier-climate relationship is poor in the HKH region. Therefore, the goal of the present work is to improve the understanding of glacier-climate relationship on a representative glacier ‘Chhota Shigri' in the western Himalaya. A number of in-situ measurements concerning mass balances, surface velocity, ice thickness and meteorology have been collected during and before the present PhD work since 2002. These data sets were first analyzed to understand the glacier behaviour and then used in the models to understand the glacier relationship with climatic variables. Between 2002 and 2013, glacier showed a mass wastage/unsteady-state conditions with a cumulative mass loss of –6.45 m w.e. Further, the ice flux analysis over 2002-2010 suggested that the glacier has experienced a period of steady-state or slightly positive mass balance during the 1990s. We first reconstructed the annual and seasonal mass balances using a degree day model from simple meteorological variables, precipitation and temperature. This reconstruction allowed us to examine the mass balances between 1969 and 2012. Since 1969, Chhota Shigri showed a moderate mean mass wastage at a rate of −0.30 m w.e. a-1. A period of steady-state between 1986 and 2000, already suggested by ice flux analysis and geodetic measurements, was confirmed. The mass balance evolution of this glacier revealed that the mass wastage is recent and provide a very different pattern than that of usually found in the literature on western Himalayan glaciers. The analysis of decadal time scale mass balances with meteorological variables suggested that winter precipitation and summer temperature are almost equally important drivers controlling the mass balance pattern of this glacier. Second, in order to understand the detailed physical basis of climatic drivers, a surface energy balance study was also performed using the in-situ meteorological data from the ablation area of Chhota Shigri Glacier. Net all-wave radiation was the main heat flux towards surface with 80% contribution while sensible, latent heat and conductive heat fluxes shared 13%, 5% and 2% of total heat flux, respectively. Our study showed that the intensity of snowfall events during the summer-monsoon is among the most important drivers responsible for glacier-wide mass balance evolution of Chhota Shigri Glacier. However, due to the lack of precipitation measurements and the strong precipitation gradient in this region, the distribution of precipitation on the glacier remains unknown and needs further detailed investigations

Full textThe Intertropical Convergence Zone (ITCZ) is a feature that results from the ocean-atmosphere interactions in the tropics around the world. The ITCZ is characterized by surface wind convergence, tall storm clouds, and it forms a belt of high time-averaged precipitation around the globe. The ITCZ undergoes seasonal migrations between 5°S and 15°N roughly following the subsolar point on Earth with the seasons, with a mean annual position located slightly above the Equator, between 2° and 5°N.
This study tested the hypothesis that there was a northward shift in the median position of the ITCZ in the first decade of the 2000’s relative to the 1900’s. This hypothesis has been posed in the literature given a weakening in the intensity of the Trade Winds observed in the southern Caribbean Sea during the first decade of the 2000’s, with concomitant ecological impacts due to weakening in coastal wind-driven upwelling. The hypothesis was tested by analyzing variations in the monthly latitudinal position of the ITCZ over the Atlantic Ocean relative to the median position computed for the period 1987–2011. The position of the ITCZ was derived from satellite-derived ocean surface wind measurements collected from 1987 to 2011. A Mann-Kendall analysis and a Monte Carlo simulation were used to test for trends in the median cross-basin latitudinal position of the ITCZ. The study included an analysis of regional changes across the tropical central Atlantic (50°W to 15°W), the Western Atlantic (50°W to 30°W), and the Eastern Atlantic (30°W to 15°W) within the tropics. The results show a slight southward trend in the median position of the ITCZ over the central Atlantic and also in the Eastern Atlantic in the first decade of the 2000’s relative to the 1990’s. While this trend is barely significant, it is likely simply due to interannual variation in the average annual position of the ITCZ.
The data were also examined for the timing and persistence of a double ITCZ in the Atlantic. The double ITCZ over the Atlantic appeared every year in February or March, with the largest separation between the northern and southern branches of the ITCZ observed in June and July.
The possible effects of changes in the average latitudinal position of the ITCZ on the upwelling in the Cariaco Basin (southeastern Caribbean Sea off Venezuela) were also examined. Anomalies of the median of the latitudinal position of the ITCZ in the Atlantic were compared with anomalies of in-situ temperature collected during the 1990’s and the first decade of the 2000’s by the CARIACO Ocean Time-Series program and with anomalies of satellite SST (from the Advanced Very High Resolution Radiometer satellite; AVHRR) from 1995 to 2016. Correlation analysis were performed between anomalies of water temperatures at various depths and anomalies of satellite SST with anomalies of the monthly mean ITCZ position with lags up to 3 months for the time series, and also just for the Cariaco basin upwelling months (December-April).
For the whole Cariaco time series there were no significant correlations between the anomalies of the ITCZ position and anomalies in subsurface temperatures in the Cariaco Basin. However, during the upwelling period, the central Atlantic and Western Atlantic ITCZ position anomalies were directly correlated with Cariaco Basin temperature anomalies with no-lag (r = 0.20), and the central and Eastern Atlantic ITCZ position anomalies were inversely correlated with Cariaco Basin temperatures (r ~ -0.22 to -0.28) with ITCZ leading Cariaco temperatures by 3 months. However, these correlations were low, indicating that other factors than the position of ITCZ latitudinal position play bigger role on the Cariaco basin upwelling variability.
Interannual variability in oceanographic and meteorological characteristics of the Atlantic Ocean are expected as a result of large-scale changes in other regions of the world, including due to changes such as the El Niño Southern Oscillation (ENSO) and the Atlantic Multidecadal Oscillation (AMO). Six oceanic-atmospheric variables are used to monitor ENSO over the tropical Pacific, while the AMO is determined by monitoring SST over the Atlantic. Correlations with lags of up to ± 6 months were conducted with those climate indices and the anomalies of the median monthly latitudinal position of the ITCZ. Significant direct correlations with ENSO (Multivariate ENSO Index) were seen in the Atlantic and Western Atlantic (r = 0.15), with ENSO leading the position of the ITCZ anomalies by 3 months. This implies that within three months after an El Niño event (warm ENSO anomaly in the Pacific) the ITCZ over the mid-Atlantic and Western Atlantic Ocean tends to shift to a more northerly position. The AMO also had a direct influence on the anomalies of the ITCZ position (r = 0.13) in the Central and the Western Atlantic, with the AMO leading ITCZ anomalies by 1 month (i.e. a warming of the North Atlantic led to a northward shift in the ITCZ one month later). Correlations between AMO and the ITCZ anomalies in the Eastern Atlantic were also direct but with no lag. Although significant, these correlations were low.
An inverse correlation (~ -0.35) was found between ENSO and anomalies of water temperature of the Cariaco Basin. ENSO lagged ocean temperature anomalies by 3 to 4 months for both the whole Cariaco time series and for the upwelling months of CARIACO data. Correlations with AMO were direct (~ 0.4); for the whole time series AMO led Cariaco temperature anomalies by 3 months, but for the upwelling months AMO lagged Cariaco temperature anomalies by one month.

Full textThe access to the Internet of the Islands of the Indian Ocean Area has the particularity of using two long submarines cables. The routes have in common to go through one of these links and introduce a delay component that can be significant. The performance of TCP is linked to the state of the route and the delay. In the situation of Reunion Island, how does a protocol having a dependence on delay such as TCP behaves? In this thesis, we propose a study of the Internet in Reunion Island. The work aims to be able to take stock of Internet connectivity. They are oriented on the one hand to characterize the connectivity at the level of the network and on the other hand to translate these characteristics at the level of the transport layer. Thus, the works presented are based on two metrology studies on the Reunion network. The first review aims to characterize the delays and the routes taken from and to the island. This work is based on a platform of measures put in place for this purpose. A road identification tool has been developed to analyze roads to and from Reunion Island. This tool uses a geolocation database built from IP addresses encountered, associated delays and information from the Regional Internet Registries. The analysis of the results shows characteristics specific to the Réunion region. The second metrology study aims to analyze TCP flows. Metrics associated with the observation of the catches of traffic are identified in order to establish the performances of TCP but also the types of traffic entering and leaving the island. Since the volume of the intercepts is important, an analysis tool for efficient and rapid treatments has been developed. The contributions of this thesis are first of all related to the Reunionese context and are extrapolated to the Internet of the Indian Ocean Zone. This thesis is meant to be an element for a reflection with all the actors of the Internet in Reunion Island

Full textThe research area is located in tidal zone on western coast of Cotentin. A first approach of the morphological process was done by a followed up of spits variations of “Pointe d’Agon” and the “Pointe du banc” by aerial-photos. The results indicated a cyclical evolution of accretion and erosion process during 40 years at Agon spit then Banc spit which progressed gradually to 500m. An unusual evolution of Agon Point was observed: transversal migration of the bar on the tidal flat by waves which formed a tombolo. The evolution of this tombolo transformed it into a small spit which progressed towards the migrant bar. The two elements will then melt to form a new spit in front of the previous spit. Granulometric index (mean, standard deviation, N index evolution) permitted to explain the different deposit conditions. North-South shore evolution of granulometric facies indicates that small energetical deposits are located on the South and high energetical deposits are located on the North of Carteret. The limit is located on both sides of the delta area of Carteret estuary. Carteret is an excellent site to study solid transport, that is why this site was selected to measure sand movement using the radioactive and fluorescent tracers. The tidal range on the Carteret coast can go up to 12m together with a strong and unidirectional tidal current (1m/s : NW). This current goes in the opposite direction to the longshore drift. The main effect of the waves on solid discharge in winter was measured by two methods: depth curves variations, sand movements by radioactive tracer. The dynamic topographical landmarking carried out using detection tracers is three dimensional and this enabled us to follow up and establish a precise morphological map. The sans movements are followed by radioactive tracers on the tidal zone according to technics used by the S. A. R. Both dynamic methods gave us the same directional transport measured by the movement of sedimentary features and by the sand movement during storm periodes. The estimated annual solid transport of 125000 m3 was computed using the morphogenesis methods after an one experiment. The exceptional hydrodynamical condition during the storm of November covered the radioelement by inactive sand up to a height of 1,25m erosion process counter acted the deposition cycle and the tracers reappeared after 6 months

Until the beginning of the '70, aircrafts of the armee de l'air performed thousands of varied missions : transport, air link, Search and Rescue. Some of them and their crews fought british / South African invaders in 1942 and others took a large part in the campaign against Madagascar! uprising in 1947-48. In 1973, because of the new political orientations in Tananarive, the french forces had to leave Madagascar.

Doctoral thesis, Università degli studi di Trieste, 2008. http://hdl.handle.net/10077/2653.
Full textLe comunità planctoniche rivestono un ruolo fondamentale nel funzionamento degli ecosistemi marini, contribuendo in maniera sostanziale ai cicli biogeochimici. Il fitoplancton, in particolare, funge da primo anello della rete trofica in quanto, attraverso la fotosintesi permette l’organicazione del carbonio rendendolo disponibile all’interno delle reti trofiche marine. Questo passaggio può avvenire sia attraverso la rete trofica classica sia attraverso il microbial loop. Lo studio quindi della comunità microfitoplanctonica, sia in termini di abbondanze sia di composizione specifica, è un passaggio obbligato per poter capire ed interpretare l’intero sistema pelagico, per conoscerne le potenzialità dal punto di vista sia ecologico sia produttivo, aspetto maggiormente legato alle attività umane. Nella prima parte di questo studio è stata analizzata una serie storica (da marzo 1986 a settembre 2005) inerente la composizione quali-quantitativa della comunità microfitoplanctonica. I dati sono stati ottenuti dall’osservazione di campioni raccolti in una stazione costiera del golfo di Trieste. La serie è stata utilizzata inizialmente allo scopo di evidenziare gli andamenti stagionali della componente microfitoplanctonica ed inoltre per valutare eventuali alterazioni/ modificazioni della struttura del fitoplancton avvenute nel corso del periodo analizzato. Sono state osservate successioni stagionali influenzate principalmente dagli apporti fluviali che in golfo dipendono essenzialmente dal fiume Isonzo, che garantisce nutrienti nei periodi di fine inverno e primavera dando la possibilità alle Bacillariophyceae (o diatomee) di sviluppare le classiche fioriture, e nel periodo autunnale, quando nuovamente le Bacillariophyceae aumentano in abbondanza. Inoltre l’analisi delle serie temporale proposta in questo lavoro (con l’applicazione dell’indice IndVal) evidenzia importanti modificazioni che hanno interessato la componente microfitoplactonica nel corso dei venti anni di osservazioni. Sono stati principalmente segnalati due momenti importanti nel corso del periodo: • a metà degli anni ’90, con la riduzione delle abbondanze dei piccoli flagellati e delle grandi Dinophyceae, lo spostamento delle tipiche fioriture di Skeletonema costatum (Bacillariophyceae) da inizio primavera ad inverno, • dal 2002 la riduzione delle abbondanze delle Bacillariophyceae con la ricomparsa dei piccoli fitoflagellati e la dominanza di specie quali Prorocentrum minimum (Dinophyceae) e Cyclotella sp.p (Bacillariophyceae). L’ipotesi principale è che nel corso degli anni ci sia stato una modificazione nello stato trofico del sistema legato ad una provata riduzione degli apporti d’acqua dolce. In particolare il fosforo è uno dei nutrienti che maggiormente limitano in questa area la crescita microalgale favorendo la presenza di specie che tollerano meglio la carenza di questo nutriente. Questo studio conferma l’utilità di programmi di monitoraggio a lungo termine che rendono possibile l’osservazione delle modificazioni del sistema nel tempo. Inoltre è stato valutato se un set di dati come quello a nostra disposizione potesse tornare utile al fine di valutare l’eventuale segnalazione di nuovi taxa per il golfo di Trieste. Infatti l’alterazione dei sistemi marino costieri può anche influenzare la distribuzione delle specie e conseguentemente favorire le “invasioni biologiche”, fattore oramai considerato in continua crescita, che contribuisce al global change portando a locali alterazioni dei processi ecologici e ad una omogeneizzazione delle comunità. Dai risultati ottenuti appare evidente che il set di dati non è adatto a trarre conclusioni in tali senso, seppure nel corso dei venti anni siano stati rilevati dei taxa di nuova segnalazione che sono diventati parte integrante della comunità microfitoplanctonica del golfo. A tale scopo risulta necessario mettere a punto strategie di campionamento mirate ad una corretta e completa stima della biodiversità, ampliando l’area interessata e con metodologie di analisi che diano la possibilità di stilare liste floristiche complete. Nella seconda parte del lavoro è stata focalizzata l’attenzione sulle zone portuali in quanto prime zone interessate da un eventuale introduzione nonché punto di partenza per molti organismi. Infatti la maggior parte delle introduzioni di specie sono veicolate dalle navi attraverso le acque di zavorra delle navi. Le acque di zavorra sono utilizzate da tutte le navi al fine di mantenere la stabilità durante la navigazioni quando queste viaggiano prive di carico ed ogni giorno enormi quantità di acqua e di sedimenti provenienti da porti e mari di tutto il mondo vengono trasportate attraverso gli oceani come acque di zavorra dalle navi mercantili e scaricate in altre aree geografiche. Quest’acqua viene prelevata dalle aree portuali costiere e trasportata nel porto successivo, ove può venir rilasciata o scambiata. A questo scopo sono stati effettuati sia campionamenti di acque di zavorra (in due importanti porti italiani quali Trieste e Napoli) sia campionamenti nell’area portuale stessa (nel porto di Trieste). Nel caso delle acque di zavorra è stato valutata la comunità microalgale presente sia nell’acqua di zavorra stessa sia nei sedimenti che si accumulano sul fondo delle cisterne (con isolamento di microalghe ancora vitali) mentre nella zona portuale è stata fatta una stima qualitativa della comunità microfitoplanctonica e una stima quali-quantitativa delle forme di resistenza (tipiche degli organismi microfitoplanctonici, in particolare delle Dinophyceae) presenti nei sedimenti del porto (con esperimenti di germinazione di cisti di Dinophyceae). I risultati hanno confermato la potenziale pericolosità di trasporto di organismi microfitoplanctonici attraverso le zavorre e anche la presenza di numerose forme di resistenza nei sedimenti portuali. Sicuramente questo studio sottolinea la necessità di predisporre piani di monitoraggio estesi alle zone portuali (sia delle zavorre delle navi sia del porto stesso) al fine di evidenziare la presenza di nuovi taxa. Questo non potrà certamente permettere di evitare l’introduzione di organismi alloctoni, ma avrà la funzione di primo campanello di allerta.

Full textTramite il Programma Man and Biosphere (MAB) l’UNESCO ha incluso il Parco Nazionale Yasuni e la Riserva Indigena Waorani all’interno della rete mondiale delle Riserve di Biofera. La Riserva di Biosfera Yasuni si individua all’interno della Napo Ecoregion nell’Amazzonia Occidentale che costituisce una tra le aree con maggior diversità sia biologica che culturale. In tale area, infatti, ci sono elevati indici di biodiversità per numerosi gruppi tassonomici e, al tempo stesso, è dimora di numerose etnie indigene, tra cui gli ultimi popoli non contattati. Tuttavia, a causa delle ingenti riserve di energia fossile e il ruolo cruciale che gioca il petrolio nell’economia nazionale, lo Stato ecuadoriano ha zonizzato aree specifiche della Regione Amazzonica adibite allo sfruttamento delle riserve energetiche ed alla produzione idrocarburifera. La Riserva di Biosfera Yasuni attualmente presenta una sovrapposizione geografica dell’80% con le concessioni per la produzione petrolifera. In passato lo sviluppo industriale nell’Amazzonia ecuadoriana ha causato importanti impatti ambientali e sociali sui territori amazzonici. Alcuni degli effetti diretti sono deforestazione per le infrastrutture (pozzi, piattaforme, oleodotti), prospezione sismica, sversamenti di idrocarburi, rilascio di gas di scarto e inquinamento chimico dovuto a smaltimento diretto dei reflui industriali nell’ambiente. Gli effetti indiretti si presentano invece principalmente associati alla realizzazione di un sistema di infrastrutture di comunicazione terrestre per la comunicazione ed il trasporto degli idrocarburi che spesso evolvono in vettori dei processi di colonizzazione del bosco primario, rappresentato dal Bosco Umido Tropicale. La colonizzazione dell’Amazzonia, infatti, diventa la principale causa dei processi di deforestazione, estrazione legale ed illegale di legname, attività non sostenibili di caccia dovuti ai nuovi insediamenti delle comunità locali. Al tempo stesso tali cambiamenti costituiscono una minaccia alla stessa sopravvivenza dei popoli indigeni in isolamento volontario (Tagaeri Taromenane). La produzione idrocarburifera ed i suoi impatti diretti ed indiretti sugli ecosistemi tropicali ha fatto diventare l’Ecoregione del Napo uno dei 14 maggiori fronti di deforestazione a livello mondiale. Tra le infrastrutture terrestri la Via Auca rappresenta la spina dorsale dell’industria petrolifera nel settore occidentale della Riserva della Biosfera Yasuní che, alimentando in modo rapido ed intenso i processi di colonizzazione idrocarburifera e agricola, configura differenti territori sovrapposti e tra loro in conflitto. Le problematiche socio-ambientali dell’Yasuní hanno assunto oggi un’elevata visibilità internazionale a causa dell’Iniziativa “Yasuni-ITT” lanciata dal Governo ecuadoriano nel 2007. Tale iniziativa internazionale si inserisce all’interno dei Protocolli di Kyoto e del mercato dei servizi ambientali e si prefigge, con la finalità di proteggere la biodiversità e i territori indigeni da un lato e di contrastare gli effetti dei cambiamenti climatici dall’altro, di lasciare nel sottosuolo amazzonico circa 850 milioni di barili di petrolio greggio. In tale modo si eviterebbe l’emissione in atmosfera di 410 milioni di tonnellate di CO2 in cambio di una compensazione economica da parte dei “paesi sviluppati” sensibili alle problematiche della deforestazione tropicale ed agli impatti dei cambiamenti climatici. In tale ricerca si intende ri-costruire una visione geografica dell’espansione della frontiera petrolifera attraverso analisi spaziali e multi temporali delle infrastrutture terrestri; allo stesso tempo approfondire la dimensione del conflitto ambientale nel contesto dell’Amazzonia ecuadoriana analizzando le dinamiche che configurano i differenti territori. Il primo capitolo affronta i diversi approcci teorici inerenti la conservazione della biodiversità ed i progetti per lo sviluppo sostenibile. Tramite un’analisi comparativa dei diversi strumenti concettuali presenta l’approccio ecosistemico e quello della cartografia critica come chiavi di lettura per analizzare i diversi progetti di territorio nell’area di influenza della Riserva di Biosfera Yasuni. Il secondo capitolo approfondisce la tematica delle informazioni geo-spaziali mettendo in relazione quelle collegate alle fonti ufficiali, con quelle ottenute tramite ricerca geografica: dalle analisi “da remoto” alla verifica al suolo (ground truth) dei dati spaziali. Si illustra inoltre la metodologia del GIS partecipativo e la combinazione degli approcci qualitativi e quantitativi per mettere campo un’analisi di tipo sistemico del territorio. Il terzo capitolo inquadra lo Yasuní come icona dell’Amazzonia. Tramite un percorso di analisi trans-scalare si affrontano le problematiche inerenti all’estrattivismo energetico e alle grandi trasformazioni infrastrutturali dalla scala del bacino del Rio delle Amazzoni, passando per la Regione Amazzonica Occidentale fino ad arrivare alla Ragion Amazzonica Ecuadoriana. In tale maniera si intende decostruire le visioni distorte e semplificate prodotte dalle narrazioni ufficiali e mediatiche, con l’obiettivo di riprendere il ruolo della geografia nella descrizione e nell’analisi delle complessità e molteplicità dei progetti territoriali che coesistono nel medesimo spazio topografico dell’Oriente amazzonico. Il quarto capitolo illustra i risultati restituiti dalla ricerca e dall’elaborazione dei dati spaziali ottenuti sul campo: l’espansione delle vie terrestri; i confini del Parco Yasuní e i conflitti tra i diversi attori, la geografia impossibile della Zona Intangible Tagaeri Taromenane (e lo scontro fra la geometria nazionale e la geografia del nomadismo), il caso “T” (Tiputini) dell’Iniziativa Yasuni-ITT e il suo dibattito artificiale sul pozzo estrattivo che è all’esterno dell’area protetta. Il quinto capitolo presenta la discussione dei risultati affrontando la problematica delle diverse rappresentazioni cartografiche e dei suoi impatti sui territori dello Yasuní. Si approfondisce inoltre la tematica dello Yasuní tra confini includenti ed escludenti, proponendo una prospettiva diversa nell’elaborazione della cartografia critica e di sintesi, con la possibilità di costruire una cartografia che aiuti la comprensione della complessità territoriale di un’icona dell’Amazzonia che non può essere semplificata e amputata da una pura enumerazione della diversità biologica.
