Short description of the intervention
Iloilo River Esplanade is a promenade and linear park along the Iloilo River, created as part of the Iloilo River Rehabilitation Project. It is the largest linear park in the Philippines and was designed by the landscape architect Paulo Alcazaren. The esplanade is one of a kind in the country that aims to foster biodiversity, store carbon by mangroves and provide protection from possible flood damages. Furthermore, the project aspires to build a lifestyle hub for the locals and promotes educational eco-tourism. The site was an existing dike road devoid of shade and originally built just as a flood control measure. The redesign has showcased its effect on public amenities, received several recognitions and has become a magnet for tourists in this city. [1, 3, 6, 7]

Goals of the intervention
1. To capture and store carbon by mangrove plantation alongside the Iloilo River.
2. To provide an improved flood protection system to the city of Iloilo.
3. To create new habitats and protect the existing ones.
4. To enhance species enrichment, especially native biodiversity.
5. To create an eco-tourism hub for the city. [1, 2, 3, 4, 7]
Quantitative targets
The project is being implemented in many phases. Each phase has its own quantitative targets. The first phase was completed in 2012, which targeted creating the Esplanade for 1.2 km. In later phases, the target was to stretch the Esplanade to 8.1 km in 2019 and to 9 km in 2020. [7]

Implementation activities
The area was previously a dike road, which was built to ease the traffic congestion and to protect the city from any possible flood. In 2010, the Iloilo City government reconsider and decided to convert the area into a linear park. The city government started work on developing the riverside stretch into a public park and launched the esplanade project as a key component of their Iloilo River Improvement initiative. The river banks on both sides of the river were built. Trees were planted, including flowering and ornamental trees. Mangroves were planted along the riversides. Fish and other species were protected and monitored. Different stakeholders were engaged at different levels and phases for the species conservation and mangrove plantation. Eco-trails were also created for the benefit of joggers and other city dwellers. Recently, the authority has started to showcase the area as an eco-tourism hub and an educational centre. [1, 3, 4, 6]

The concept of the park has gained attention nationwide and other cities are taking initiatives in replicating the ideas and creating similar NBS structures. [7]
Impacts, benefits
Description of environmental benefits
1. The promenade along the river provides extra protection from any possible flooding events. The grey structures and the mangroves along the shorelines protect the city from floodwater damage.
2. The mangroves are the natural and native tree and shrub species along the riverside. It is home to 22 of the country’s 35 mangrove species. The plantation of more mangroves has improved the ecosystem of the area as it supports other species and creates habitats where species can thrive. This has improved the overall species diversity in the area and in the river water.
3. The conservation and protection of the river have also rejuvenated the fish species found in the water. The species variety has been improved since the inception of the project.
4. In addition to protecting the city from floods and providing habitats, the mangroves are also very efficient in carbon absorption. This is expected to help the city to fight climate change effects in the long turn.
5. Iloilo City’s growing bird-watching community has also noted that the resurgence of mangroves in the locale has heralded the return of migratory waterbirds to the river, enriching an already diverse population of kingfishers, egrets, herons, “tikling” (buff-banded rail), “maya” (Philippine oriole), “trivis,” “tigbabalang,” and “tarurok,” among others, in the area. [2, 4, 5, 11]
Description of economic benefits
1. The project has turned an area with illegal structures built along the banks, reclamation, congestion at the Iloilo wharf, overfishing and pollution into a lush and exciting linear park for the locals to enjoy. The area received stimulation in development. This has increased the real-estate development and property price to 18,000 pesos or more per square metre from 2-3,000 pesos per square metre.
2. The project has revamped the tourism sector of the city. The esplanade has gained attention countrywide. This has helped the city to get visitors from different regions.
3. It has created more business and employment opportunities in the area. [8, 10]
Description of social and cultural benefits
1. It is a popular tourist spot where visitors enjoy a leisurely stroll and enjoy the serene views along the river. Locals usually go to the esplanade for a hearty jog or to spend with friends and family.
2. The esplanade has become a tourist attraction, which helped the Iloilo City to be identified as a liveable city, among others.
3. The project also removed any kind of vandalism issues along the riverside, which has marked the space as a safe space for people to enjoy.
4. The promenade has provided added safety from climate change disasters such as floods.
5. As the space is open for all, this has improved the connection between people and nature. The place has become very popular and gets routine visitors regularly. They use the space for jogging, running or other kinds of exercises.
6. The project has created an educational ecotourism hub, which promotes awareness related to NBS and its benefits. Collaboration with the University of the Philippines Visayas is supporting scientific research on a GIS-based App development with tagged locations of mangrove species. [1, 2, 3, 5, 8, 9]

The esplanade has provided a good relaxing area in the difficult times during the COVID pandemic. Locals reported that the visits helped them to soothe their minds. For many locals, who lost their jobs during the pandemic, the river has provided a good fish catch for the family to consume and sell at the local market. People got benefited from the project in many aspects during the pandemic. [5]
