[EN] The concept of sustainability when referring to food production rests, in general, on 3 main aspects: 1) respect for the environment; 2) economic and social benefits for all involved in production; and 3) production of sufficient quantity of quality food at an accessible price. In this contribution we focus on the main aspects of the traditional sheep's milk and cheese production (under the Denomination of Origin Idiazabal Cheese) in the Basque Country that contribute primarily to its sustainability. It is based on the local latxa or carranzana breeds of sheep, adapted to the mountainous terrain. The sheepherder takes advantage of local resources to reduce management costs by combining indoor dry forage and concentrates with outdoor grazing throughout lactation, according to local pasture availability, and thus avoiding having to buy large amounts of feed. This system facilitates recycling of manure, fertilising pastures and forest at the same time. Use of local breeds helps maintain biodiversity of sheep breeds. Cheese is produced industrially (44.5% of the total cheese produced in 2008) from milk of many flocks, or artisanally (38.3%) by the sheepherders with the milk from their own flocks. Transforming their own milk into cheese is advantageous for the following reasons: 1) higher economic returns as compared to selling the milk to cheese factories because cheese price directly sold to consumers is more competitive than industrial cheese sold in supermarkets; 2) increases the value of women's work (over 80% of the cheese makers are women) in the community and their self-esteem; 3) it creates rural jobs and contributes to rural development; 4) we have demonstrated both with experimental and commercial flocks that part-time grazing allows the sheepherder to obtain high yields of milk, and cheese, of high nutritional and functional quality. Currently a less sustainable, intensive sheep's milk production with foreign, imported breeds kept indoors constantly is gaining favour among milk producers because of its perceived higher economic profitability.

[ES]En este proyecto se recoge un análisis de las diferentes tecnologías de centrales termosolares. Las energías renovables tienen un papel fundamental en el abastecimiento energético futuro, ya que son una fuente inagotable con un impacto medioambiental mínimo. Dentro de las renovables, la energía termosolar es una de las más destacables en España, que se ha situado como el país líder en termosolar. Existen cuatro tecnologías diferentes para este tipo de centrales, por lo que el objetivo de este trabajo es profundizar en su conocimiento y proporcionar un criterio objetivo que permita seleccionar la más adecuada en futuras instalaciones. Para ello, se considerarán tanto aspectos técnicos como económicos, con el fin de estudiar las principales ventajas y desventajas de cada tipo.

[EUS] Hiriko ekosistemak garrantzi handiko gune berdeak bilakatzen ari diren honetan, geroz eta gehiago dira eremu naturalen kudeaketarako estrategiak garatzeko biodibertsitatearen eta ekosistemen zerbitzuen balioa kontuan hartu behar dela uste dutenak. Ekosistemen zerbitzuen (gizakiak ekosistematik eskuratzen dituen onurak) kudeaketa jasangarria garatzeko, zerbitzuon eskaintza eta eskaria kontuan hartzen dituzten aspektu biofisiko, sozio-kultural eta ekonomikoak ezagutzea beharrezkoa da. Ikerketa honetan, hiritarrek Bilboko Eraztun Berdeko ekosistemek eskaintzen dituzten zerbitzuen inguruan duten pertzepzioa ezagutu nahi da, jendeak eskaintzen diren zerbitzu guztiak hautematen dituen jakiteko. Horretarako, ikertutako arean ekosistemen hiru zerbitzu kartografiatu dira (aspektu biofisikoa) eta 111 pertsona inkestatu dira euren iritzia ezagutzeko (aspektu sozio-kultural eta ekonomikoa). Hala, ikusi da hiritarrek naturak ongizaterako duen garrantzia ezagutzen dutela, nahiz eta ekosistemen zerbitzuen kontzeptua ez ezagutu. Dena dela, ekosistemak egoera onean mantentzeko prest daude, bereziki garrantzitsuak iruditzen baitzaizkie erregulaziozko zerbitzuak (airearen kalitatea) eta zerbitzu kulturalak (lasaitasuna, aisia, eta naturarekin kontaktua). Beraz, emaitza hauek kontuan hartu beharko lituzkete Bilboko Eraztun Berdeko ekosistemen kudeaketaz arduratzen diren agintariek, etorkizun hurbilean zerbitzuen eskaintza eta eskariaren arteko kudeaketa orekatua garatzeko.
