1. General information
2. Objectives of the intervention
Goals of the intervention
The goals of the project include:
-To retain rainwater and thus improve infiltration [1].
-To enhance storm-water drainage systems [1].
-To reduce soil erosion, stabilize and regenerate soils on slopes and at the same time improve crop productivity, increase biodiversity and reduce risks from landslides, erosion and flood risk [1].
-To improve water flow and stabilize creek slopes while simultaneously reducing the risk of flooding and improving the connectivity of green areas in the city [1].
-To create a resilient community garden and school gardens as an ecosystem-based Adaptation (EbA) capable of meeting the needs of a community [1].

Implementation activities
1. 36 farms are applying a system of live and dead barriers to prevent erosion and ditches in the middle of the coffee plantations to help retain rainwater and thus improve infiltration [1,2].
2.Implementation of 5 school gardens and community gardens with drip water system [1,2].
3. Restoring coffee plantations, forest, and digging infiltration ditches [7]. The project has already made progress, some of the data on their web page include [1,2]:
- 432 hectares have been restored on 36 coffee farm
-34,217 linear meters of infiltration trench.
-4,790 m3 of water infiltrated in the ditches,
- 49,875 trees, of which 46,850 are coffee trees and 3,125 are fruit trees,
- number of beneficiaries: 2,811
- 280,190.07 m3 of potential infiltration during 1 year (considering 147.7 days of rain)
4. Restoration of urban and peri-urban streams-connectivity. 5,183 linear meters of urban streams, 4,565 plants between forest and fruit trees, number of beneficiaries 11,639 [1].
5. Of the 30 absorption wells, 7 wells have been built. An infiltrated volume is estimated 28,117 m3 [1].
6. Restoration of 150 hectares of critical ecosystems. 17.93 ha have been sampled for the identification of flora and fauna. A nursery has also been created for the restoration of flora and fauna [1,2].
7. Community harvest water system and ecological sanitation systems in schools and communities. 10 harvest systems and 2 ecological sanitation systems have been created [1,2].
8. Construction of drinking water well [2].

5. Innovation
Type of innovation
Please specify technological innovation
The project is considered an infrastructural innovation process due to the construction of water retention structures, community harvest water systems, and digging infiltration ditches to reduce the impacts of flooding [1].
Novelty level of the innovation
Please specify novelty level of the innovation
"The term ‘sponge city’ is used to describe an urban area that is creating green spaces to tackle flooding. Cities around the world, from Berlin to Wuhan, are now pursuing this innovative strategy. Globally, the use of nature-based solutions for adapting to climate change is known as Ecosystem-based Adaptation" [4].
Replicability/Transferability
Please specify Replicability/Transferability
City Adapt project advocates creating green spaces to tackle flooding and strengthen local resilience and adaptation to climate change. Cities worldwide, from Berlin to Wuhan, are now pursuing this innovative strategy with The term ‘sponge city’. City Adapt adopted this idea to be replicated in El Salvador, Mexico, Jamaica, Bhutan, Cambodia, Myanmar and Laos. However, It is unclear if the model has been adopted elsewhere in El Salvador yet [1,4].
