Many policymakers are responding to the Sustainable Development Goals (SDGs) by integrating multiple economic, social and environmental concerns into their development plans. Much of the recent research on SDGs has sought to help policymakers with this cross-sectoral integration by developing evidence-based models and analytical frameworks that can identify linkages across a wide range of issues. Fewer studies have examined the governance arrangements needed to align agency and other stakeholder interests behind integrated solutions. This is a significant gap because policymakers will need to understand both issue linkages and governance arrangements that can help align interests to make integrated solutions effective.

This study has aimed to fill that gap by determining whether and to what extent three different dimensions of governance—horizontal coordination, vertical coordination, and multistakeholder engagement—affected narrowly drawn efforts to mitigate climate change and achieve other development objectives. The study sought to draw lessons from a series of case studies focusing on the governance arrangements that supported 1) co-benefits, 2) sustainable transport, 3) integrated solid waste management and 4) the water-energy-food nexus in the Asia-Pacific region. Overall, the case studies suggest that the greater the number and diversity of issues in an integrated solution, the more countries will need to strengthen institutional structures and enhance decisionmaking processes to advance that solution.

However, more coordination within and engagement beyond government may not be needed for all integrated solutions. Particularly when there are already close relationships between issues and sufficient capacities to manage related interests, less coordination and engagement may save time and resources. This suggests that policymakers and researchers may want to take a step back from advocating for multi-level, multi-stakeholder governance for all integrated solutions. Instead, such recommendations are arguably better seen as contingent, depending on the content of the integrated solution and other factors such as the capacity of relevant agencies to coordinate different interests.

位於屯門環保園的WEEE‧PARK今日開幕,行政長官林鄭月娥主持儀式。她致辭時說,WEEE‧PARK開幕是香港發展「轉廢為材」基建的重要里程碑,顯示政府實踐資源循環的決心。

林鄭月娥表示,WEEE‧PARK投產確保本港有能力妥善回收和處理本地產生的廢電器電子產品,為今年稍後全面實施的廢電器電子產品生產者責任計劃提供所需設施。

WEEE‧PARK採用先進技術和設備,把廢棄的「四電一腦」,即冷氣機、雪櫃、洗衣機、電視機、電腦及其相關產品轉化為有價值物料,並修理仍可運作的電器,轉贈有需要家庭。

由8月1日起,「四電一腦」銷售商須為消費者安排除舊服務。環境局局長黃錦星在開幕禮上說,WEEE‧PARK為日後落實廢電器電子產品生產者責任計劃奠下基礎,當局也歡迎業界推出其他措施處理廢舊電器,適應巿場發展,滿足本地需求。

他又說,WEEE‧PARK是配合香港資源循環藍圖2013-2022的重要基建之一,而位於大嶼山小蠔灣的首個有機資源回收中心O‧PARK也將於今年稍後啟用,進一步落實藍圖。

WEEE‧PARK設展覽廊和導賞服務,團體可於4月3日起致電2290 9500預約參觀。

市民可致電熱線2676 8888,預約WEEE‧PARK營辦商上門回收欲棄置的廢電器電子產品。

渠務署小蠔灣植物苗圃佔地近2,000平方米,環境清幽,綠意盎然,培植50多種本港原生植物。園境師肩負綠化之責,因應品種特性移種於不同設施,既收美化環境、維持生物多樣性之效,也令渠務建設氣象一新。

許樂謙在本港修讀城市規劃和園境建築,加入渠務署近兩年,是該植物苗圃園境師之一。他表示,在美化設施方面,署方近年較多採用原生植物。

「過去不少項目均用外來品種,因為那些花朵比較漂亮;但原生植物對生態有更多益處,部門也鼓勵我們多用。有了這個苗圃,正好研究合適的品種和所需的環境。」

 

原生植物美化環境

苗圃2014年中投入服務,園境師每周視察兩次,紀錄植物生長情況,並研究種植方法。在不同品種中,他們初步選定嶺南山竹子、梭羅樹,青葙、薏苡移植。

許樂謙解釋,四種植物各有特色,可配合渠務設施美化,甚至污水淨化的工作。

「嶺南山竹子是原生常綠喬木,果實是野生獼猴的主要食糧。梭羅樹有香味,蝴蝶和蜜蜂都受吸引,常常飛來採蜜。青葙形態既優美又特別,呈串形,是一種頑強的植物,土壤不佳也能生長。薏苡這品種挺不錯,有淨化污水中氮和磷的作用。」

青葙、薏苡適合在河道栽種,目前遍植於萬屋邊和九龍坑河道;梭羅樹、嶺南山竹子則適合渠務設施,青衣基本污水處理廠、昂坪污水處理廠已經採用。

綠化項目惠及社區

園境師負責綠化項目,由挑選品種、繪圖、規劃設計,以至日後定期護理工作,均一手包辦。

唐翠珊兩年前加入渠務署,參與沙田污水處理廠的綠化工程。她表示,廠房佔地28公頃,三成面積落實園境綠化,相等於半個維多利亞公園。

唐翠珊指,渠務設施進行綠化,有助提升形象、改善環境,惠及整個社區。「沙田污水處理廠是個好例子,道路兩旁有茂密的樹木,並有綠化天台。垂直綠化方面,我們在一些污泥貯存缸上種植,吸引雀鳥昆蟲前來棲息覓食,增加生物多樣性。」

選擇種植品種時,園境師兼顧建築物的結構和安全,會為維修機電設施預留通道。鑑於天台泥層較薄,栽種根淺植物會較合適。倘若建築物的位置較近河邊或山邊,選用的植物則應耐風、耐旱,並能長期承受陽光照射。

為加深市民了解本港污水處理和防洪工作,渠務署1月27至28日於沙田污水處理廠舉行開放日,節目豐富,免費入場。
