城市防洪,有許多功夫默默藏在看不見的地下!桃園市政府水務局辦理「平鎮區上海路雨水下水道改善工程」,改善既有雨水下水道箱涵老化、破損情形,完成既有雙孔箱涵修繕,全長約130公尺,透過老舊設施補強延壽,提升排水效能並降低積淹水風險。

水務局長劉振宇表示,此次工程最大的亮點,是不用大規模開挖道路,也能替超過30年的舊箱涵「脫胎換骨」。水務局採用SPR內襯工法,直接在既有箱涵內部進行修復補強,不僅可省去傳統開挖、回填等施工程序,縮短工期,也能大幅縮小施工範圍,減少道路封閉,維持地面交通順暢。工程在去年10月3日開工,今年8月21日順利完工,10個多月的施工期間,上海路排水箱涵仍然堅守崗位維持排水通暢,服務120公頃的集水範圍沒有因為施工造成任何淹水的問題。

請繼續往下閱讀...

劉振宇提到,雨水下水道平時藏在道路之下,看不見卻是豪雨來臨時守住城市的重要防線。此次修繕完成後,可改善既有箱涵破損情形,恢復並提升排水功能,進一步強化上海路周邊地區的防洪韌性。

劉振宇強調,面對短延時強降雨日益頻繁,水務局持續推動雨水下水道建設及老舊設施改善,依不同現地條件導入合適工法,讓地面少一點施工陣痛,地下多一分防洪韌性,一段一段修好城市的排水脈絡,讓下一場大雨來時,水走它該走的路,市民走自己的路。

Keelung Heping Island Geopark Intertidal Zone Ecological Restoration Night Tour to View Rare Species such as Swimming Crabs

Keelung Heping Island Geopark is included in the management of the North Coast and Guanyin Mountain National Scenic Areas. After more than ten years of rest and restoration and no fishing, the intertidal zone is rich in ecology, with swimming paddle crabs, devil sea urchins, bead snails and other species appearing. The park cooperates with Environmentally Friendly Seeds to launch a season-limited night tour "Island Day Tour" from May to October, leading the public to observe intertidal creatures.

Kenting advocates "returning crabs to nature": land hermit crabs cannot be reproduced artificially, and all sold on the market are caught in the wild.

The Kenting National Park Management Office and ecological experts launched the "Return Crabs to Nature" initiative, pointing out that it is extremely difficult for terrestrial hermit crabs to survive in artificial environments. 100% of the individuals sold on the market are caught in the wild. Current laws and regulations are difficult to enforce. Citizen awareness and education are needed to break the chain of harm from trade to protect the coastal ecology of the Hengchun Peninsula.

Diversity of land crabs in Hengchun Peninsula plummets, experts warn of ecological crisis

The Hengchun Peninsula was once a paradise for land crabs with the highest diversity in the world. However, in recent years, due to the invasion of exotic yellow crazy ants, illegal commercial capture and regulatory loopholes, almost all large land hermit crabs have disappeared, and coastal forests have become dead. Scholars have called for the strengthening of habitat conservation and law enforcement.

Bengaluru citizens protest Karnataka law allowing infrastructure in protected parks

Thousands protested in Bengaluru's Lalbagh Botanical Garden against a Karnataka law permitting up to 5% of protected parkland for public infrastructure, which could affect 12 acres of Lalbagh and 15 acres of Cubbon Park. The protest follows earlier opposition to a metro line and now targets a tunnel road project requiring felling of 900 mature trees, reflecting broader global urban struggles over green space as cities face space constraints.
