Short description of the intervention
Around 90% of Guyana’s population lives in an area that is below sea level, with many inhabiting flood-prone areas along the coast. The coastal plains are also home to about 75% of the country’s economic activities, including almost all of Guyana’s agricultural production. Over the years, degradation and loss of mangrove forests have resulted in increased coastal flooding and saltwater inundation of agricultural land. Mangroves contribute substantially to sea defence in Guyana by damping wave action and reducing wave energy, trapping sediments and stabilizing shoreline substrates while playing an important role in carbon sequestration.
The Guyana Mangrove Restoration Project was executed during 2010-2013 under the National Agricultural Research & Extension Institute. Following completion of the Project phase and given the importance of mangroves to Guyana’s coastal defences, mangrove restoration and management were integrated into NAREI (the National Agricultural Research and Extension Institute), a national institution that promotes climate-smart agriculture and resilient citizens.

Goals of the intervention
Guyana is particularly vulnerable to sea-level rise stemming from climate change, plus regional shifts in the height of the sea. Close to 80 per cent of Guyana's population lives in the low–lying coastal region. In fact, some of the historically habitable sections are already below sea level and by 2100, scientists project a global sea-level rise of 2.6 feet (80 centimetres)—and as much as 6.6 feet (2 meters). For example, the 2005 flood was concentrated in the most heavily populated regions of the country, resulting in some 274,774 persons or 37% of the national population being severely affected by the floodwaters. The flooding event claimed the lives of 34 persons. The government of Guyana estimated that the mean annual temperature in Georgetown increased by 1.0°C within the last century. Climate change' effects require complex solutions and as such the government's aim was to help build up the coastal nation’s natural sea defences. More precisely the goals of the intervention were:
1. To increase the recovery of the mangroves along the Guyanese coast, including: introducing alternative restoration methodologies, such as planting coastal grass species, constructing fences to control grazing, hydrologic restoration
2. To conduct a biodiversity assessment of mangrove sites that can be used as a baseline for future assessments and as the basis for future management plans for these areas.
3. To develop effective protection and/or rehabilitation of mangrove ecosystems (a soft, low-cost option for augmenting the country’s sea defence system)
4. To increase public awareness and education on the benefits of the mangrove forests
5. To counteract the decrease in the yield of crops as temperature increases in different parts of Guyana
6. To reduce and prevent coastal erosion by implementing mangroves which act as wave breakers to protect coasts, coastal communities and infrastructure from the onslaught of strong waves and winds.
7. To provide excellent habitat for different types of plants and animals and prevent loss of biodiversity
8. To mitigate climate change (carbon sequestration through reforestation and forest preservation) and adapt to its effects (sea defence, biodiversity). (1,2,3,4)

Implementation activities
Prior to the intervention technical research aimed at resolving some of the overall and critical questions underlying the issues of mangrove loss and restoration was essential. Key topics concerning the ecology of Guyana's mangroves, such as the impact of agricultural pollution; the best practices for planting and the causes of sudden erosional loss, pest, and disease among others, have not been answered in the specific context of the Guyana coast. As the project found its feet and technical experts were brought in, better monitoring protocols were introduced and more training carried out. Before a site is selected, research was carried out: the section was measured using GPS and the soil elevation was checked to see if it is conducive to mangrove planting. The work doesn’t end there: measurements were carried out quarterly in the first year of planting, twice in year two, and annually thereafter. A core activity under the Mangrove Management Action Plan is the rehabilitation of mangrove fields. This element of the programme involves selecting existing mangrove forests for protection and identifying sites that are more difficult to rehabilitate but are of high value in terms of sea defence. Mangrove seedlings are being planted along different sections of coastline.(2,3,5)

NBS intervention implemented in response to an Regional Directive/Strategy
Yes
Please specify the "Regional Directive/Strategy"
Under the EU’s Global Climate Change Alliance (GCCA), the Guyana Mangrove Restoration Project (GMRP) supports Guyana’s policies on sea defence, climate change and mangrove management. (1)
NBS intervention implemented in response to a national regulations/strategy/plan
Yes
Please specify the national regulations/strategy/plan
In preparation for the project the Government of Guyana in January 2010, boldly declared all mangroves on State lands as ‘Protected Trees’, following an amendment to Regulation 17, of the Guyana Forest Act. In keeping with this declaration, any unauthorized removal of mangrove forests on State Lands is now considered illegal, and any contravention to this regulation is subjected to prescribed penalties, including monetary fines and/ or imprisonment. Another document the project relied on was: Guyana’s National Mangrove Management Action Plan (NMMAP) where the overall objective of the NMMAP was to:
‘respond to climate change and to mitigate its effects through the protection, rehabilitation and wise use of Guyana's mangrove ecosystems through processes that maintain their protective function, values and biodiversity, while meeting the socio-economic development and environmental protection needs in estuarine and coastal areas(4)

On the policy and regulatory side, mangrove protection is now considered in the National Forest Act and the Second National Biodiversity Action Plan, which creates a supportive policy framework; it is now also fully considered in the new draft of the Forest Plan. The quality and effectiveness of regulations protecting mangroves are being reviewed.(3)

Which of the involved actors was motivated by this model?
Please specify technological innovation
Parts of the intervention were considered innovative, for example, previously, Guyana built artificial sea walls to protect the coast. These can be very costly to construct and maintain. The project implemented innovative measures designed to increase the recovery of the mangroves along the Guyanese coast, including introducing alternative restoration methodologies, such as planting coastal grass species, constructing fences to control grazing and hydrologic restoration. The propagules were planted in polythene bags. (1,6)
Please specify social innovation
From a policy point of view with the help of local communities, new policies regarding mangroves restoration were included, especially since before the intervention, there was no clear mandate for the management of mangroves. (5)
Novelty level of the innovation
Please specify novelty level of the innovation
It was not clear from the sources if the project was inspired by international or local action. It suffices to say that through 2010-2012 this intervention was unique for the coastal area of Guyana and only after it ended (in 2014) there were other initiatives implemented. (5)
Please specify Replicability/Transferability
The project has many strands which are relevant for the post-2015 Rio, combining budget support with sustainable development (green economy, climate change mitigation), and women's empowerment.(3)
Impacts, benefits
Description of environmental benefits
Under the project’s restoration program (2010-2012) 420 000 black and red mangrove seedlings have been produced and planted with community involvement.
5 km of mangroves have been restored along the East Coast of Demerara, West Coast Berbice and Corentyne Coast. Hard structures have been designed and constructed to increase sedimentation in selected areas.
Some 36.5km of mangroves are now monitored and protected by a newly set up mangrove ranger unit comprising 8 rangers. (3) The black mangrove is locally known as courida or black mangrove. It is the most important and dominant mangrove species in the open mudflats of Guyana. It is tolerant to high saline conditions and the tree grows in the form of isolated groups or woodland formations. The tree is fairly large and may grow up to 20-25 meters in height and 40 centimetres in diameter. This species regenerates and coppices well and can be managed under a coppice system. The red mangrove is an evergreen tree, which grows to about 25 meters in height and 40 centimetres in diameter. The roots systems stabilize the trees and act as the first line of defence against wave action. (6)
Observations indicate that the establishment of hard structures (rip-rap) increases sedimentation and promotes natural regeneration, highlighting the importance of the infrastructure support component (groins and breakwaters). (3)
The black mangrove, or the honey mangrove, has small white flowers that produce abundant nectar and because of the benefits provided by the mangrove forests, particularly sea defence protection, they are being protected by the Government and other stakeholders. Mangroves also produce significant leaf litter that benefits estuarine food chains: many of which depend upon the continuously dropped evergreen leaves from the mangrove vegetation for subsistence. Mangrove creates important protection, foraging and breeding area for birds, fish, mussels and crabs.(7)
Description of economic benefits
A mangrove reserve group composed of women producers has been established to promote alternative livelihoods in communities along the coast. (3)
Description of social and cultural benefits
Several actions have been and will keep being implemented in support of public awareness and community involvement. Participation of communities living close to mangrove fields is indeed very important both for protection and for mangrove monitoring.
A mangrove reserve women producers group has been established to promote alternative livelihoods in communities along the coast. It won the Caribbean Tourism Organisation/Travel Mole Award for Biodiversity Conservation in 2012.
Mangrove protection and rehabilitation is generating significant benefits for local communities, through participation in mangrove seedling production as well as the sale of non-timber forest products, honey from beekeeping and other mangrove-based produce.
A Mangrove Visitor Centre hosting 3 000 students per year and 200 other visitors per month has been established. It is becoming a fixture on annual events such as the Amerindian Pageants as well as Guyana Fashion weekend. The first Guyana Mangrove Forum, entitled “Restoring and managing mangrove ecosystems in a changing world”, was held in Georgetown from 11 to 14 April 2013 to raise the profile of mangroves and build linkages between Guyanese and regional researchers.
