class="richtext"> <p>Alors que 2020 devait être une « année décisive pour sauver la biodiversité » avec de grands rendez-vous internationaux comme le Congrès mondial de la nature et la COP15 Biodiversité, un autre événement planétaire, la pandémie liée au coronavirus elle-même liée à la crise de la biodiversité, a remis en question ce calendrier. Il n’en demeure pas moins que l’érosion de la biodiversité se poursuit : la qualité et les étendues de milieux naturels continuent de baisser et le nombre d’espèces menacées continue à croître.</p> <p>Selon l’IPBES, 75% des milieux terrestres et 66% des milieux marins ont été « significativement modifiés par les activités humaines », « 23% des surfaces terrestres ont montré un déclin de leur productivité du fait de la dégradation des sols » et le taux d’extinction des espèces atteint près d’un million. De même, la Commission européenne constate dans un rapport d’octobre 2020 que l’UE « n’a pas réussi à enrayer le déclin des espèces et des types d’habitats protégés dont l’état de conservation est préoccupant » et que les « principales pressions liées à l’utilisation des terres et des ressources en eau subsistent encore », i.e. agriculture intensive, modification des régimes hydrologiques, urbanisation et pollution. Différents moyens existent pour « ramener la nature dans nos vies » comme le souhaite la stratégie de l’UE en faveur de la biodiversité à l’horizon 2030 : mise en place d’aires protégées, utilisation de solutions fondées sur la nature et lutte contre l’artificialisation des sols (avec, entre autres, le développement de l’agriculture urbaine et de la végétalisation en ville). C’est tout l’objet de l’ingénierie écologique et du génie écologique qui, en plus de travailler à restaurer des milieux dégradés, peuvent contribuer à reconstituer des milieux naturels.</p> </div> </div> </div> <div id="annuaire-list"> <div class="list-item"> <div class="hcontainer"> <div class="clearfix"> <a class="right image" style="background-image:url(https://learnandconnect.pollutec.com/wp-content/uploads/2020/12/agriculture-urbaine.jpg)" href="https://learnandconnect.pollutec.com/categ2/agriculture-urbaine-et-vegetalisation"> </a> <div class="left text"> <a href="https://learnandconnect.pollutec.com/categ2/agriculture-urbaine-et-vegetalisation" class="annuaire-list-h2"> <h2> Agriculture urbaine et végétalisation </h2> <span>2 Fournisseur(s)</span> </a> <p class="catchline">Les projets d’agriculture urbaine sont en plein essor.
