Monitoring, Evaluation, and Learning (MEL) is central to ensuring the sustainability of our tree restoration efforts. This building block allows us to track the progress of tree growth and refine our restoration strategies for better outcomes. We employ drones to capture before-and-after images, providing a clear visual comparison of the impact of our restoration work. By continuously assessing our efforts, we can make data-driven adjustments that enhance the effectiveness of our conservation initiatives.

Environmental restoration initiatives need to report to their donors and other stakeholders the impact of their investments. The TREEO Impact Dashboard is a platform where the results from implementer’s projects are showcased, thereby providing evidence from their planting and monitoring efforts which they can use for further reporting and sharing with their stakeholders. The Impact Dashboard, with single sign-on capabilities, displays the data from tree monitoring, including sequestered CO2, biodiversity monitoring, and data from the socioeconomic surveys if performed. This fosters easy reporting as well as provides interactive and clean visualisation for the implementer’s stakeholders (donors, sponsors, government agencies, and companies). Impact reporting data comes from the TREEO Cloud and can be exported and published based on each project’s needs.

Integrated Land Use Planning involved strategically allocating land for agricultural and conservation purposes to balance human and wildlife needs. This comprehensive approach ensured sustainable land use that supported both community livelihoods and wildlife conservation. The planning was necessitated by the 10% fence plan, where 10% of beneficiaries' land was secured with an electrified short fence. Farmers utilized the secured land to incorporate skills honed from climate-smart agriculture training, maximizing production, while 90% of the land was left fallow for wildlife and livestock. Currently, a total of 129 acres have been secured by the 10% fence plan, with over 1,000 acres (90%) left as room for wildlife to roam. Up to date, there has been zero elephant conflict registered within the fences, securing crops and property with zero crop raids or property damage.

As a key measure to raise transparency within small-scale and artisanal fisheries, a robust registration and licensing system needs to be put in place. It is advised to introduce mobile, and if possible, community-led, on-site licensing initiatives, providing immediate support for licensing with registered tax numbers. This enhances the accessibility of the licensing process and compliance among fishers, due to a sense of community ownership. In cooperation with a dedicated governmental body, such as the Department of Fisheries and the local research institute, a digital management system should be developed. This central database helps to monitor licenses and registrations from multiple locations and thus enables conclusions to be drawn about the status of fish populations.

Controls and inspections are key principles of curbing IUU fishing. Improving the quality of patrols through specialized training for inspectors is essential to monitor fishing activities directly on board or after landing. Additionally, processors are encouraged to conduct self-inspections to prevent the processing of undersized fish and enforcing regulations in their businesses, thereby reducing reputational risks in the industry. The development and / or revision of standard operating procedures for these controls ensures that they remain relevant and effective in the face of changing IUU fishing practices.

To ensure that fish production supported by the GP Fish is an accessible protein source also for the most vulnerable, GP Fish regularly tracks fish prices and the share of total production accessible to the food insecure population. According to the conducted surveys 90 %, 58 %, 84 %, and 99 % of farmed fish is accessible for the food insecure population in Madagascar, Malawi, Zambia, and Cambodia respectively (status 2023). These numbers again highlight the potential of extensive and semi-intensive aquaculture techniques to supply affordable protein and nutrients in areas with a high share of vulnerable people.

Under the application of the trap for intermittent harvest, the best results were achieved with the following combination of variables: maize bran (supplementary feed) x maize bran (trap bait) x O. Shiranus (species) x 2 fish/m2 (stocking density).

The total yields under this combination were 25 percent higher than in the control group with single batch harvest. A higher stocking density (3 fish/ m2) led to a slightly higher total harvest in the control group, but to a lower net profit. The use of pellets reinforced both effects and was the least economical.

Results from the on-farm trials (see Figure 1) have demonstrated the functionality and the excellent catch effect of the traps. Over the three-month on-farm trial period, the trap was used 2 to 3 times a week and a total of 27 times. On average, around 120 small fish – an equivalent of 820 grams – were caught each intermittent harvest. With the use of the trap, all households reported that they now eat fish twice a week. Before that, fish consumption was between one and four times a month.

The benefits:

• Reducing the competition for oxygen and food among the fish in the pond and thus measurable increase in yield.
• Improved household consumption of small, nutritious fish and better cash flow.

Success factors:

• Traps are easy and inexpensive to build (USD 3).
• Traps are easy to use, also for women.
• Directly tangible added value thanks to easy and regular access to fish.

Examples from the field

Overall, the user experience of households engaged in the on-farm trials was very positive:

“As a family we are now able to eat fish twice and sometimes even three times a week as compared to the previous months without the technology when we ate fish only once per month.” (Doud Milambe)

“Catching fish is so simple using the fish trap and even women and children can use it.” (Jacqueline Jarasi)

“It is fast and effective compared with the hook and line method which I used to catch fish for home consumption that could take three to four hours but to catch only three fish and thus not enough for my household size.” (Hassan Jarasi)

The local community was consulted into the spatial planning process. The process involved holding big workshops for local community and inviting several interest groups, especially those of livestock owners, tourism workers, and hunting enthusiasts. The purpose was 2 main things; 1) to collect local data and knowledge into the planning product and more importantly to build a sense of ownership and belonging of the local community to the potential planning product.

Data from various sources were collectively integrated and put into a spatial prioritization and optimization algorithm based on targets stemming out from the Primary Management objectives of the Reser. This Algorithm is known as MARXAN working under a process termed as simulated annealing.  

The resulting planning product is then shared back to the local community and other stakeholders including governmental and non governmental entities to collect thier feedback to further tweak the product for maximum sustainability.

The next city selected was San Mateo del Mar in Oaxaca, this location has multiple current and future challenges regarding the climate crisis, its location and geographical conditions make it a city highly vulnerable to the effects of climate change.

Together with the Municipal Government of San Mateo del Mar, we were able to work closely with the Ikoots community, the Institute of Indigenous Peoples (INPI) and the Indigenous Women's House (CAMI).
