Klima-aldaketaren eraginak euskal kostaldeko mendebaldeko sakonera handiko begetazio azpimarealean

[eus] Euskal kostaldeko mareazpiko begetazioak aldaketa esanguratsuak jasan ditu azken hiru hamarkadetan. Aurretik egindako ikerketek jakinarazi dute aldaketa horiek klima-aldaketak eragindakoak direla. Ikerketa honen helburua inpaktu horri buruzko informazio gehiago lortzea da. Horretarako, sakonera handiko uretako fitobentosaren osaerari eta ugaritasunari buruzko balioespena egin da. 2014. urteko udan 7 trantsektu ezarri ziren, Kobaroneko muturretik Muskizeko muturreraino. Trantsektu horiek aurretik ikertuak izan ziren 1982 eta 2007 urteetan, eta laginketa suntsitzailea egin zen. Analisi estatistikoek aldaketa esanguratsuak erakusten dituzte sakoneko (9-11m) komunitateetan azken 32 urteetan. Uraren tenperaturaren emendioa eta eguzki-erradiazio altuagoa detektatutako aldaketen erantzuleak izan daitezke neurri batean. Pterosiphonia complanata espezie esziafiloaren gainbeherak eta Cystoseira baccata eta Aphanocladia stichidiosa espezieen ugaritzeak hipotesi hori azaltzen dute. Espero genuenaren kontra, Gelidium corneum espeziea, sakontasun gutxiko uretan gainbehera bortitza jasaten ari dena, ez da 9 metrotik beherako sakonerara lekualdatu. Hala ere, ezin da ziurtatu egungo ingurumeneko baldintzak optimoak ez direnik G. corneum espeziearen garapenerako 9-11 metroko sakoneretan. Migrazio bertikal hori ez gertatzearen arrazoi onargarriena C. baccata- rekiko lehiakortasuna dela dirudi. Bestalde, C. baccata hiru dimentsiotako habitatak eratzeko gai den tamaina handiko alga bat da, espezie askorentzat babesleku gisa diharduena. Ondorioz, haren hedapenak G. corneum-ek sakonera txikiagoetan betetzen zuen funtzioa ordezka lezake neurri batean.

Lengua y derecho a la educación en la Comunidad Autónoma del País Vasco : reflexiones jurídicas sobre el tránsito hacia un nuevo modelo

The article analyzes the legal regime of Euskara in the education system of the Autonomous Community of the Basque Country (capv). In the capv, the legislation recognizes the right to choose the language of study during the educational cycle. The students are separated into different classrooms based on their language preference. This system of separation (of language models) has made it possible to make great strides, although its implementation also suggests aspects which, from the perspective of a pluralistic Basque society on its way towards greater social, political and language integration, call for further reflection The general model for language planning in the capv was fashioned in the eighties as a model characterized by the guarantee of spaces of language freedom, and the educational system was charged with making the learning of the region’s autochthonous language more widespread. At this point, we already have a fair degree of evidence on which to base an analysis of the system of language models and we are in a position to conclude that perhaps the educational system was given too heavy a burden. Official studies on language performance of Basque schoolchildren show (in a way that is now fully verified) that not all the students who finish their mandatory period of schooling achieve the level of knowledge of Euskara required by the regulations. When faced with this reality, it becomes necessary for us to articulate some alternative to the current configuration of the system of language models, one that will make it possible in the future to have a Basque society that is linguistically more integrated, thereby avoiding having the knowledge or lack of knowledge of one of the official languages become a language barrier between two communities. Many sides have urged a reconsideration of the system of language models. The Basque Parliament itself has requested the Department of Education to design a new system. This article analyzes the legal foundations on which the current system is built and explores the potential avenues for legal cooperation that would make it possible to move towards a new system aimed at guaranteeing higher rates of bilingualism. The system would be sufficiently flexible so as to be able to respond to and accommodate the different sociolinguistic realities of the region.

Environmental taxes and the Double dividend hypothesis

In this End of Degree Dissertation I built a basic economic model, where two perfectly competitive markets interact, as a tool to understand, illustrate and evaluate environmentalfiscal reforms that have already been implemented or have been announced in many developed countries. Thus, in this dissertation I try to explain as simply as possible the theorical aspects of the “double dividend” hyphotesis and provide a numerical example with illustrative purpose.
