Els esforços de les campanyes fetes per les ONG van portar a un primer plànol internacional els diamants de guerra - els conflictes lligats als conflictes armats -a finals dels anys noranta. Com a resposta, es va formar el Procés de Kimberley (PK), un fòrum negociador entre estats, ONG i indústria, per debatre possibles solucions que posessin fre al comerç de diamants de guerra. Menys de tres anys després es va adoptar un sistema voluntari de certificació internacional anomenat Sistema de Certificació del Procés de Kimberley (SCPK). El SCPK regula el comerç de diamants en brut certificant tots els diamants legals. Aquest article repassa el problema dels diamants de guerra, explica com una campanya internacional va despertar la consciència sobre el problema, i com el procés de recerca de solucions va culminar en el PK. L’ anàlisi es centra en els diferents actors implicats (ONG, estats i indústria) i les seves interaccions canviants al llarg de la campanya i dels esforços realitzats per crear una regulació internacional. Com a conclusió, es destaquen algunes lliçons fonamentals, en termes analítics i d’acció, derivats d’aquest estudi de cas.

Campaign efforts by NGOs initially put conflict diamonds on the global radar screen in the late 1990s. In response, the Kimberley Process (KP), a negotiation forum between states, NGOs, and industry, was formed to discuss possible solutions to curb the trade in conflict diamonds. Less than three years later, a voluntary, global certification named the Kimberley Process Certification Scheme (KPCS) was adopted. The KPCS regulates the trade of rough diamonds by certifying all legitimate diamonds. This paper outlines the problem of conflict diamonds, how a global campaign raised awareness about the issue, and how the process of solution building unfolded in the KP. My analysis focuses on the diverse set of actors (NGOs, states, and industry) and their changing interactions over the course of the campaign and global regulation efforts. I conclude with several key lessons that capture important elements observed in this case study.

Globularia alypum és un arbust termòfil típic de la regió oest del Mediterrani. Aquest nanofaneròfit té un patró de floració molt ampli. Les poblacions primerenques floreixen des del Juliol fins al Desembre i les poblacions tardanes des del Gener fins a l’Abril. L’objectiu del projecte és esbrinar quins factors climàtics determinen la fenologia de la floració de l’espècie a partir de mostres d’herbari i conèixer l’abast geogràfic d’ambdós patrons de floració a la península Ibèrica i França. També l’estudi d’altres característiques fenològiques en relació amb el clima: els braquiblasts i les espigues de capítols. Els plecs d’herbari han estat georeferenciats per ser utilitzats en un entorn SIG junt amb les dades del clima i s’ha realitzat una anàlisi estadística. El resultats mostren que les poblacions primerenques creixen majoritàriament en zones costaneres mentre que les tardanes ho fan en zones continentals. Les poblacions primerenques creixen en àrees on les temperatures (mitjana, mínima, màxima i mínima del mes més fred) són més altes que les tardanes per l’efecte temperador del mar. Al analitzar totes les poblacions, el nombre de mesos des de la transició floral es correlaciona negativament amb la temperatura mínima mensual i la temperatura mitjana mensual en tots els mesos, mentre que amb la temperatura màxima mensual entre Octubre i Abril. Al estudiar sols les poblacions tardanes les correlacions són similars, però no en les primerenques on no se’n troba cap. Les correlacions entre el nombre de mesos des de la transició floral i les variables climàtiques anuals són iguals, a més de trobar-se una correlació negativa amb la temperatura mínima del mes més fred i l’índex tèrmic, i positiva amb l’índex de continentalitat. No s’ha trobat cap diferència en presència de braquiblasts segons la població, però sí en les espigues de capítols, essent més freqüents en les poblacions primerenques. Es suggereix que la temperatura és un factor més determinant per a les poblacions tardanes, mentre que es desconeix si és la precipitació en les primerenques. Tampoc es té coneixement sobre si les diferències entre els dos patrons són genètiques o fenotípiques i quin mecanisme possibilita el desenvolupament de braquiblasts i espigues de capítols.

Seasonal trends in littertall and potential mineral return were studied in two cork-oak forest sites in the northeastern Iberian peninsula. The estimated average litter production was 3.9.M- gy.e1ahar for one site and 4.6 .M- gy.e1ahar for the other; these figures are similar to those reported for holm-oak (Quercus ilex) forests in the same area. Seasonal litterfall patterns were typical of Mediterranean forest ecosystems. Leaves accounted for 46 to 78% of the total dry matter. Their annual weighted-average mineral composition was low in macronutrients (N 8-9; K 4-5; Mg 0.8-1.3; Ca 9-10 and P 0.4-1 m-)g.1g and relatively high in micronutrients such as Mn (2-2.2 m-)g.1g or Fe (0.3-0.4 m)-g..1g Minimum N and P concentrations were found during the growth period. Estimates of potential mineral return for an annual cycle were N 38-52, P 2.1-5.2, K 20-28, Ca 44-53 and Mg 5.4-5.0 k-,g.1ha depending on the site biomass and fertility

Cork is the bark of the cork oak tree (Quercus suber L), a renewable and biodegradable raw bioresource concentrated mainly in the Mediterranean region. Development of its potential uses as a biosorbent will require the investigation of its chemical composition; such information can be of help to understand its interactions with organic pollutants. The present study investigates the summative chemical composition of three bark layers (back, cork, and belly) of five Spanish cork samples and one cork sample from Portugal. Suberin was the main component in all the samples (21.1 to 53.1%), followed by lignin (14.8 to 31%), holocellulose (2.3 to 33.6%), extractives (7.3 to 20.4%), and ash (0.4 to 3.3%). The Kruskal-Wallis test was used to determine whether the variations in chemical composition with respect to the production area and bark layers were significant. The results indicate that, with respect to the bark layer, significant differences were found only for suberin and holocellulose contents: they were higher in the belly and cork than in the back. Based on the results presented, cork is a material with a lot of potential because of its heterogeneity in chemical composition

Earthquakes represent a major hazard for populations around the world, causing frequent loss of life,human suffering and enormous damage to homes, other buildings and infrastructure. The Technology Resources forEarthquake Monitoring and Response (TREMOR) Team of 36 space professionals analysed this problem over thecourse of the International Space University Summer Session Program and published their recommendations in the formof a report. The TREMOR Team proposes a series of space- and ground-based systems to provide improved capabilityto manage earthquakes. The first proposed system is a prototype earthquake early-warning system that improves theexisting knowledge of earthquake precursors and addresses the potential of these phenomena. Thus, the system willat first enable the definitive assessment of whether reliable earthquake early warning is possible through precursormonitoring. Should the answer be affirmative, the system itself would then form the basis of an operational earlywarningsystem. To achieve these goals, the authors propose a multi-variable approach in which the system will combine,integrate and process precursor data from space- and ground-based seismic monitoring systems (already existing andnew proposed systems) and data from a variety of related sources (e.g. historical databases, space weather data, faultmaps). The second proposed system, the prototype earthquake simulation and response system, coordinates the maincomponents of the response phase to reduce the time delays of response operations, increase the level of precisionin the data collected, facilitate communication amongst teams, enhance rescue and aid capabilities and so forth. It isbased in part on an earthquake simulator that will provide pre-event (if early warning is proven feasible) and post-eventdamage assessment and detailed data of the affected areas to corresponding disaster management actors by means of ageographic information system (GIS) interface. This is coupled with proposed mobile satellite communication hubs toprovide links between response teams. Business- and policy-based implementation strategies for these proposals, suchas the establishment of a non-governmental organisation to develop and operate the systems, are included.

The historical evolution of vegetation in the former Sils Pond (la Selva) during the second half of the 20th century is described through the study of past(Bolòs, 1954; Vilar, 1981) and present-day (Mercadal, 2002) vegetation cartography, the first aerial photographs (1956 and 1980) and current orthophotos (2000). This inland pool was finally drained in 1851 and most of its area was converted into meadows (Gaudinio fragilis-Arrhenatheretum elatioris Br.-Bl. in Br.-Bl., Roussine & Nègre 1952), a semi cultural community which was very distinct florally, for the Mediterranean region. The results demonstrate that in the last 50 years changes in land use have transformed the former landscape, which was prominently meadow-like and grain-producing, into woodlands, wet grasslands, developed areas and sub-Mediterranean forests, with the consequent loss of meadow areas and floristic diversity. In response, based on historical cartography, we propose spaces to prioritize for recovery and management such as meadow areas
