Observation and monitoring of restored mangrove sites

Four types of action are considered in this building block:

  1. Observation missions by the local community that will consist in assessing if the recruitment of seedlings (propagules) takes place, defining the growth level (height) and evaluating the possible damage caused by the surrounding herds (especially by zebu herds) or climatic hazards;
  2. Mission to monitor the state of the water channels to see if the banks are still stable and discharge (flow-through) is possible, especially during high water tides (02 months after planting);
  3. First estimate of the level of success, e.g. approximate area of seedling settlement (03 months after restoration).
  4. Long-term monitoring (biomass and biodiversity) using drone and satellite imagery; this step will be carried out jointly with the GIZ, the Malagasy Ministry of the environmental and sustainable development (MEDD) and the local community (from 03 months after restoration and onwards).

To protect the young seedlings from zebu migration and illegal logging (mangrove wood is of high value) and other hazards in the reforested sites, two guards from the local community work on a rotating basis for the first 4 months. A motorboat was bought for the guards to allow them easier access the mangrove sites. In general, it is very important that the community is the leading entity in the monitoring process to ensure the sustainablity of the method.

A good and long-term monitoring system needs to be in place to successfully protect the new seedlings from any hazards. Illegal logging and damage caused by zebu herds is very common in our area.

Preparatory meeting, mobilization of the community and implementation

Prior community meetings were organized in the neighbouring village to raise awareness about the importance of mangrove restoration. During these meetings, the community was informed of the principles of the resoration method and the steps involved. Since mangrove restoration does not require any particular technical expertise (know-how), the entire community was targeted (women, men and youth) and mobilized for further actions. Furthermore, local authorities, state technical services, as well as administrative authorities were also involved, so that the method could easily be replicated elsewhere.

In-depth discussions with the local community and technical experts were crucial for a suitable design of the channel system in this area. The channel was dug according to the local topographic context, i.e. depth of the channel, angle of channel site, length, starting point, etc.

 

(1) 50 members of the local community were mobilized to dig the channel; (2) An area of 40 ha of degraded mangroves was identified (3) A channel system with a total length of 2200 m was dug to promote the natural recolonization in the degraded areas.

To motivate the different community groups (women, men and youth) for the restoration work, their interests must be considered. Furthermore, their future benefits (ecosystem goods and services) must be discussed in an understandable and participatory way. This, most importantly, includes food security and income generation.

Community-based identification and validation of the restoration site

The identification and validation of the restoration site was carried out jointly with the local community to promote its adherence to the process. The regional forest service and technicians from the NGO Conservation International (CI) were also included to ensure the technical feasibility of the proposed site.

Local community elders, who know the historical, environmental and topographic context, are usually very good advisers for restoration site choice. They can indicate where degraded mangrove areas (inland) with some remaining plants can be found (the restoration site must have been a mangrove ecosystem in the past). These are usually suitable sites for reforestation/restoration.

The community should be the leading entity in the process, as they are very familiar with the local context and are the beneficiaries. They should have the right to manage the mangrove areas through a formal management contract, because ownership gives the responsibility and commitment to manage the site sustainably.

 

From a technical point of view, the following criteria are crucial:

  • Existing flood zone during low tides and present canals;
  • Soil type (muddy or sandy-muddy) and pH;
  • The salinity of the water must be brackish.

Local knowledge and participation is crucial to ensure the sustainability of the restoration sites. In our case, the identification of the restoration site without the knowledge of the local elders would have been much more difficult and time-consuming, as we are not familiar with the area and little information is available on some areas in Madagascar. 

Community engagement

We involve all stakeholders in all decision-making and invite all community members wo might be affected by projects to community meetings to ensure that there is no misunderstandings. It should be noted that we explicitly expect communities to contribute to the success of projects - be it through digging a well themselves, providing bricks when preschools are built, or taking care of planted trees. 

WfZ is known to be able not only to implement projects but as as well to support them after the initial successful implementation. This means, we do not only install the Zoë-pumps but we also maintain and service them. The same goes for preschools and education projects. We support projects on the long run and the communities are aware of it. Community members value this ongoing support highly and are keen to participate in learning opportunities.

From our experience we highly recommend to be mindful to have some reserves left to maintain projects over a long period of time and to assume that it takes the community some time to get accustomed to manage projects themselves effiiciently. Only then can charitable work coming from outside into a community become successful and truly sustainable

Female empowerment

As women in rural malawian families are usually responsible to cook for their family members, they are also the ones who predominantly collect firewood, as well as to pump and carry water. 
Women are therefore the ones whose training will have the biggest impact on how they perform these practices for example: If a tree is cut off at about 1m height above ground it will coppice, if however the roots are dug out to get more firewood, then a close to irreversible damage will incur, so training is very important. 
By training and hiring mostly women for all steps required to restore a landscape we give them the basic tools and education to bring sustainable change to their landscape - as well as changing the basic income structures as their work often becomes the main source of income for the family.

At Wells for Zoë we have women in leadership positions managing several project implementations from the Secondary Girl Student Project, and the Preschool Project where caretakers are being educated. They also visit reforestation and restoration projects and influence our hiring policy of local workers involved in the projects. 

Generally speaking, being able to hire local women and pay them is a majorly important factor to enable female empowerment. 

Female employees and workers are grateful and report that the payment and education they receive, changes their lives to the better as they can pay schoolfees for their children and provide a richer diet for themselves and their family or start small scale businesses with the income earned. 

Interactive technology for conservation

Technology knows no barriers and we are yet to innovate and discover more with a changing world.

 

By using the underwater cameras it has allowed us to bring ahead the live viewing and monitoring where previosuly we were limited. Thus allowing us to better engage with local fisher community, for them to get a sense of ownership and unite to better understand and protect this ecosystem. 

 

This has also facilitated the data sharing of the status of the reef locally and across different channels but also to open the door for more scientific collaboration locally and internationally. 

 

 

  • Local community buy-in
  • Interactive technology 
  • Data sharing

Technology here not only brought live viewing and interaction but a completely new level of underwater restoration. Fish and coral interaction can be securely monitored allowing scientist to discover more about underwater interactions.

Drone mapping and remote sensing

Inspired by our transparent way of GPS-mapping our more than 2000 installed Zoë-pumps we knew we had to apply the same principle and expand it to show and document our tree planting projects. 

Now we have an elegant solution: We create GPS-Polygons of planting sites by walking around it with a simple smart phone app. We then import these boundary files into the drone mission planning app and fly a drone over the planting site capturing thousands of images. 

These are then stitched into a large photogrammetric map that can transparently show and document landscape change through the work happening on the ground. Additionally all workers inspecting the sites take thousands of GPS-photos which are displayed on our custom built map as well. 

We are lucky enough to have a malawian team that is highly skilled and trained well enough so that we can 100% rely on their work and the results they deliver.
Apart of that it is important to have reasonable drone laws in a country, as well as having access to a drone and a pilot. 

In the very beginning of the drone monitoring we had to research the best workflow to map an area with no network terrain-aware. As this took a lot of time and turned out to be actually not even that complicated we wanted to share our knowledge and created a learning series on drone monitoring in cooperation with One Tree Planted and it is now freely available on youtube and covers all there is to know:

Evidence through research

Pathogen and disease detection under the PREDICT and PREDICT-2 projects as well as other research initiatives have generated a strong evidence base on the drivers of zoonotic diseases. In Liberia, the finding of Ebola virus antibodies in a bat provided evidence that Ebola is circulating in wildlife in the West Africa region and signaled that there are ongoing spillover risks requiring public health attention. 

Involvement and partnership of international and national institutions ensured best practices in research activities. The National Public Health Institute provided important leadership to support outreach on the significance of the Ebola finding. Another key factor was the model practices demonstrated by the sampling team, involving safe handling and sampling and attention to animal welfare, which itself helped to increased awareness of these aspects by observant communities.

In the past, communities in Liberia have distrusted foreign researchers and do not typically have direct access to the findings from research activities. Communities were aware of the sampling activities around their villages; by seeing Liberian scientists involved in this work with their own eyes, they were more receptive to the findings. 

Awareness raising

Many people interact with wildlife and domestic animals in Liberia, but overall awareness about zoonotic disease risks is low. Raising awareness involved information about the purpose of the project, as well as dedicated engagement using the 'Living Safely with Bats' visual book. This messgaing integrated biodiversity and health information, in line with a One Health approach. 

Collaboration on an international project allowed for sharing and optimization of materials, including adaptation of the information and visuals in the 'Living Safely with Bats' book to the Liberian context. Holding engagement sessions as a group allowed for questions and norms to be considered in a respectful and open community-led manner. The trust established allowed for the messages to be positively received. 

Changing perceptions and norms takes time and sustained engagement, particularly in settings where health literacy is limited. With accurate information and practical strategies for their context, communities are empowered to take on actions that reduce disease risk and protect animals and ecosystems.

Trust building

Communities were initially concerned about outsiders coming to their villages. Sustained engagement with community leaders, and outreach to community members, helped to establish trust over time. In particular, a key feedback was hearing the appreciation that the team came back to share information.

Implementation by Liberian scientists ensured the local conditions, complexities of the issue, and needs were considered. Building in time and resources to return to communities from the start of the project was important, to be able to honor promises to return to share information from the evidence base. 

Perception and understanding of the issues varies by community. Local leaders, such as Paramount Chiefs, play a crucial role in their communities and are vital partners in trust building.
