Uno sguardo ai cinque fattori principali responsabili della perdita di biodiversità su scala globale La biodiversità sta vivendo una vera ...
forte declino
La biodiversità sta vivendo una vera crisi a livello globale ed è in <anchor>forte declino</anchor>. Il tasso di estinzione delle specie va oggi ad una velocità senza precedenti nella storia dell’uomo, fino a 100 volte più elevato del normale ritmo degli ultimi 10 milioni di anni. L’ambiente sta cambiando così velocemente che molti organismi non riescono ad adattarsi alle nuove condizioni. La perdita di specie comporta gravi conseguenze per gli ecosistemi di cui facevano parte. Infatti, all’interno di un ecosistema tutte le specie sono intrecciate e in equilibrio tra loro, come a formare una rete. Ogni volta che una specie scompare parte della rete si indebolisce. Detto ciò la scomparsa di una specie non comporta necessariamente il collasso dell’ecosistema. Infatti, proprio la diversità biologica e la sua complessità rendono l’ecosistema resiliente e quindi capace di rispondere ai cambiamenti. Purtroppo oggi, molte delle attività umane esercitano una forte pressione sulla natura, mettendo a rischio la sopravvivenza non di una sola specie, ma di migliaia allo stesso tempo. L’ultimo rapporto del IPBES (piattaforma intergovernativa scienza-politica sulla biodiversità e i servizi ecosistemici)  sulla valutazione globale della biodiversità e dei servizi ecosistemici ha stimato che circa 1 milione di specie animali e vegetali è oggi a rischio estinzione.

# Global Assessment Report on Biodiversity and Ecosystem Services

![Cover of the Global Assessment Report on Biodiversity and Ecosystem Services](data:image/svg+xml;charset=utf-8,%3Csvg%20xmlns%3D'http%3A%2F%2Fwww.w3.org%2F2000%2Fsvg'%20viewBox%3D'0%200%2071%20100'%2F%3E)

IPBES is to perform regular and timely assessments of knowledge on biodiversity and ecosystem services and their interlinkages at the global level. Also addressing an invitation by the Conference of the Parties of the Convention on Biological Diversity (CBD) to prepare a global assessment of biodiversity and ecosystem services building, inter alia, on its own and other relevant regional, subregional and thematic assessments, as well as on national reports.

The overall scope of the assessment is to assess the status and trends with regard to biodiversity and ecosystem services, the impact of biodiversity and ecosystem services on human well-being and the effectiveness of responses, including the Strategic Plan and its Aichi Biodiversity Targets. It is anticipated that this deliverable will contribute to the process for the evaluation and renewal of the Strategic Plan for Biodiversity and its Aichi Biodiversity Targets.

The IPBES Global Assessment on Biodiversity and Ecosystem Services is composed of 1) a Summary for Policymakers (SPM), approved by the IPBES Plenary at its 7th session in May 2019 in Paris, France (IPBES-7); and 2) a set of six Chapters, accepted by the IPBES Plenary.
