Short description of the intervention
The marshes in southern Iraq, formed by the Tigris and Euphrates Rivers, are home to one of humanity’s oldest cultures, once the third-largest wetlands in the world. The Eden In Iraq wastewater garden project started as a humanitarian project that has developed as a necessity for the people of Al Chibaish and the localities surrounding the town. This water remediation project holistically looks at wastewater, trying to include this type of water and its nutrients in a sustainable form by using it to create green spaces. The Eden project in Iraq regards human waste as a valuable source of nutrients and freshwater, which can add to local greenery and landscape beauty if properly treated close to its source. From a climate change point of view, the project focuses on the creation of a wetland with wastewater that can support a garden within the marshes of Iraq. Marsh restoration is a powerful tool against warming temperatures and loss of vegetation, especially in arid areas such as Iraq. From a biodiversity point of view, the project bares a great deal of significance as marshes support a myriad of rare wildlife and rich biodiversity. (1,2,3)

Goals of the intervention
The intervention has a strong social component as it responds to the needs of Iraqi citizens to access fresh, uncontaminated water as well as a green space in a climate known for rising temperatures, intense droughts, declining precipitation, desertification, salinisation, and the increasing prevalence of dust storms.

The project aims to fulfil the following goals:
1. To protect the rich cultural heritage and traditions of the marshes of the original Garden of Eden and current and future Marsh Arab communities, one of the world's oldest and most distinctive cultures.
2. To utilise simple and sustainable wastewater recycling technology to support a garden (the very first demonstration Wastewater Garden) that embodies the rich cultural heritage and tradition of the marshes and the Marsh Arab community - to collect waste, treat wastewater, and advocate better health and sanitation practices.
3. To renew environmental stability and conserve a natural environment of Outstanding Universal Value.
4. To safeguard the marshes and their unique ecosystem that sustains the economy and livelihood of the Marsh Arabs.
5. To build a wetland - Wetlands have been aptly called “the kidneys of the planet” for their ability to cleanse water of pollutants and remove carbon from the atmosphere.
6. To offer opportunities for ecological education. (1,2,3,4,5)

Implementation activities
In 2013-2017, the initial phase of the project was funded in Singapore by a $65,000 Ministry of Education Research Grant awarded to Associate Professor Meridel Rubenstein and Assistant Professor Peer Sathikh from the School of Art, Design and Media of Nanyang Technological University, Singapore, in collaboration with Dr. Sander van Der Leeuw, Dr. Mark Nelson, and Dr. Davide Tocchetto. This initial grant allowed their international team to research and design the garden, with numerous trips to the area sites. In addition, the university awarded $36,500 to exhibit all aspects of the project (designs, photographs, videos, and writing) at the National Design Centre in Singapore in 2017. This comprehensive exhibition of the project and its relation to Mesopotamian history is available. (4) Between 2014 and 2016, three of the largest town councils in the region enthusiastically approved of the garden by donating the use of five large sites, each serving 5-10,000 people. They understood that their current situation endangers both their health and the health of the wetlands. (3) The project continues to this day however it is dependent on funding.

This project is a collaboration between co-directors artist/photographer Meridel Rubenstein and environmental engineer Dr. Davide Tocchetto, with environmental engineer Dr. Mark Nelson and engineer and managing director Nature Iraq NGO, Jassim Al-Asadi. This project, sponsored by NGO Nature Iraq in Iraq and the Institute of Ecotechnics in both the UK and USA, responds to decades of conflict in this region and continued tension due to climate change, external water rights violations, and social upheaval. Initial support since 2011 spans from Iraqi municipalities, the region and State, to international sources. (2)

The intervention was not created as a response to a local strategy; however, local authorities participated in different stages of the action. It is however unclear if the local authorities have indeed a strategy that focuses on green spaces or wastewater treatment. This certainly is an effect of the long years of the Iraq war. (2)

Which of the involved actors was motivated by this model?
Please specify technological innovation
The Eden In Iraq water remediation project aims to use simple, sustainable wastewater recycling technology to support a garden that embodies the rich cultural heritage of the Marsh Arab community. The wastewater will go into a “subsurface flow wetland” that transforms organic material into mineral substances using bacteria. This cleans the wastewater while simultaneously providing nutrients for the plants and fruit trees.(5)
Please specify novelty level of the innovation
Sources mention that the team that works for the Eden in Iraq project has been implementing wastewater gardens in Algeria, Africa, Mexico, and Indonesia, also helping the local communities of these countries.(4)

Impacts, benefits
Description of environmental benefits
The project is ongoing, and some reports have been issued. According to a study the vegetation of constructed treatment wetlands is selected from two main types: free floating plants (e.g., Eichhornia spp., Lemna spp., Pistia spp.) and emergent plants, rooted in soil, usually called emerged macrophytes (e.g., Phragmites australis, Canna spp., Scirpus spp., Typha spp., Iris spp., Carex spp.) (1)

Regarding the impacts, the implementation of the project will result in:
-Creation of green, vegetated garden areas which will absorb carbon dioxide and other atmospheric trace gases, thus improving air quality and providing net carbon storage.
-Permanent improvement of water quality in the nearby environment and in the receiving water environment compared with the current discharge of raw, untreated sewage.
-An increase in floral diversity and the creation of newly vegetated areas are expected. All the species are either native or already found in the area and either collected in the wild or grown in local plant nurseries. Thus no exotic plants are used.
-The project will produce new green areas – both the treatment wetlands and the subsurface irrigation gardens. The creation of a garden will help maintain local and migratory bird populations since additional habitats and food sources will be created. (6)
Description of economic benefits
The project aims to work with the local community as an important step to safeguard the marshes and their ecosystem that sustains the livelihood of the region's inhabitants. Investing in Eden in Iraq – the wastewater garden in the Marshlands – is expected to generate immense spillover to the country’s economy. In 2011, the United Nations Integrated Water Task Force for Iraq estimated that an investment of $33,000 to restore 2.5 acres of the marshes would result in an economic benefit value of $171,300 over 40 years. (3)
Description of social and cultural benefits
The Marsh Arabs have maintained a traditional water-based way of life, including distinctive reed architecture, weavings, and water buffalo trade. Their architecture appears unchanged on cylinder seals and stelae dating over 5,000 years old. (3)

Between 2014 and 2016, three of the largest town councils in the region enthusiastically approved of the garden by donating the use of five large sites, each serving 5-10,000 people. They understood that their current situation endangers both their health and the health of the wetlands.
During the design and planning process throughout the past 5 years, the project has been received and approved by local, provincial, state and environmental authorities. (3)

Comments and notes
Additional insights
The Marsh Arabs developed their unique way of life around the resources of the marsh, once the third-largest wetlands in the world. The Tigris and Euphrates Rivers cross on the eastern edge of the marshes at the Shatt al-Arab, and this intersection is thought to be a possible site of the historical Garden of Eden.
