Abstract
Water stress assessments on basin level of 96 SCA sites and global water issues affecting industry are presented. Four tools are evaluated with the aim to find indices that measure water stress, i.e. lack of water of good enough quality for humans and the ecosystem. Water indices, developed through research, become more accessible when they are in water tools, developed by non-governmental organisations, corporations or financial institutions. Two indices in WBCSD’s Global Water Tool and three indices in WWF-DEG’s Water Risk Filter totally give each site five assessments. Both tools give assessments without showing the level of certainty, which makes it difficult to evaluate reliability without more local knowledge. Baseline Water Stress,... (More)

Baseline Water Stress, one of the indices in the study, estimates the level of water stress in the basin. The index shows 47 SCA sites in basins with indications of water stress. Presumably, several sites are affected by water stress. (Less)
Popular Abstract (Swedish)
I uppdrag av SCA gjordes en studie om vattenstressbedömningar för avrinningsområden där SCA har massa- pappersbruk, pappersbruk eller fabriker. Fyra vattenverktyg undersöktes i syfte att hitta index som mätte vattenstress, d.v.s. bristen på vatten av tillräckligt bra kvalitet för att kunna användas av människor och ekosystem. Vattenstressindex, som tagits fram genom forskning, blir mer tillgängliga när de finns i vattenverktyg, som utvecklats av NGOs, företag eller finansiella organisationer. Två index i WBCSDs Global Water Tool och tre index i WWF-DEGs Water Risk Filter resulterade i fem bedömningar för varje anläggning i studien. I studien ingick 96 anläggningar. Vattenverktygen ger i nuläget bedömningar för stora områden utan att visa... (More)

Vattenverktygen ger i nuläget bedömningar för stora områden utan att visa konfidens- intervall för de resultat som presenteras. Mer lokalkännedom skulle behövas för att utvärdera om resultaten stämmer med verkligheten. Detta gäller för alla index som beräknas på nivån av avrinningsområden eller länder. (Less)
