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). The implementation site was the Espinal Sports Field, with a shaded and revegetation space, and in the CAMI with a support space to preserve and promote the community's ancestral knowledge.

The first edition of the project took place in Boca del Río, Veracruz, where the logistics and execution of the activities at the selected implementation site were worked out in conjunction with the municipality's City Hall.

The Parque Lineal Dren B, due to its needs related to construction characteristics, dynamism of activities and proximity to school equipment, represented an ideal site. It is composed mostly by a long pavement slab and few tree species that provide shade, when combining these characteristics with the climatic conditions of the area, it potentiates the heat island effect, making its habitability complicated during daylight hours with sunlight due to the high temperatures reached; and due to the high rainfall, accumulation of urban solid waste in the sewage system and high ground surface sealed with pavement, there are usually areas with flooding, promoting the generation of bad odors and affecting the inhabitants of the area.

The solutions for this edition of the project were oriented to generate a water infiltration garden, greater shade spaces and the construction of play options for children, accompanied by color interventions throughout the park.

The results were:

Environmental connectivity device - demonstration project.

• 25m2 infiltrative garden
• Unstructured playground of 42.31m2
• 2 interventions in urban furniture elements, pergolas on two benches (2.16m2 and 1.45m high).
• Installation of informative and environmental education screens on Arroyo Moreno (in collaboration with Ecopil) along the Dren B Linear Park.

• Impact area of 4,248m2

Since 2019, the Fisherwomen and Fishermen Network has promoted effective and collaborative participation in both thematic groups and the core group, ensuring the sharing of knowledge and responsibilities. This participatory, transparent and effective approach has been fundamental to the cohesive functioning of the Network.

Since its inception, each member has actively participated in one or more of the network's activities, fostering the transfer of leadership within the network.

During these years, its members have led various initiatives, such as the development of work plans, organization of trainings, photographic exhibitions and conversations on digital platforms on topics such as gender, fishery management tools and community photography. In addition, they have supported the review of documents and materials relevant to the fishing sector. These activities have been possible thanks to the commitment and collaboration among the members of the different thematic groups, who have designated representatives (men and women of different ages) to form the core group. The representatives play a crucial role in sharing information, objectives and needs of their respective groups, communities and the fisheries sector in general.

In summary, the Network has established a participatory and transparent dynamic that has facilitated the success of its initiatives and strengthened collaboration among its members over time.

During the COVID-19 pandemic, the Fishermen and Fisherwomen's Network was created as a space for collective action with the intention of ensuring a space for participation, organization and representation of the fishing sector. Since its formation, the Network has sought to ensure the representation of the sector by bringing together diverse actors, both individuals and community organizations and groups. Each member voluntarily participates in thematic groups focused on areas such as monitoring of fishery resources and environmental conditions (community monitoring and oceanographic monitoring group), improvement of fishing practices (fisheries group), inclusion of youth and promotion of gender equity in fisheries (youth and gender group), and valorization of the sector through (community photography group).

Each thematic group develops work plans aligned with the Network's mission and values. So far, these groups have played a crucial role in raising the visibility and recognition of the fishing sector, actively participating in national and international meetings to disseminate its values and promote actions in favor of sustainable fishing. In order to join a thematic group, interested persons must fill out a form, which will be evaluated by the core group for integration.

The local residents who were previously excluded from the various cultural tourism activities and festivals centering on the World Heritage property started to independently host village activities and built up their capacities for delivering and managing events. 

The initial residents group started to participate in the operations of the Suwon Heritage Night Walks in 2017 as traffic control staff. As the number of festivals that were hosted to celebrate Suwon Hwaseong as World Heritage increased, such as the Hwaseong by Night, World Heritage Festival, and Media Art Shows, the number of jobs available for the residents also increased. 

The Haenggung Village Cooperative Association was established on 31 May 2021 and it consists of 46 members. The main line of work is creating content and activities for visitors. 
The association is composed of 4 sub-groups each named “jigi”, which in the Korean language means friends: 

• Haenggungjigi, who focuses on providing event support, information, sanitation and the operation of activities; 
• Donghaengjigi, a group that creates the content and stories of the village tours; 
• Surajigi that promotes and shares research and education on food; 
• Cheongnyeonjigi, the group that monitors and conducts evaluations of activities. 

Dissemination and communication of the interventions took place through local press conferences organized by Colectivo Tomate as implementing partner, together with local governments, COMEX, GIZ and other strategic allies.

In addition, microsites were created on Google Sites that serve as hubs of accessible and updated information on the project. These microsites provide details of the interventions, methodologies employed, results obtained and next steps. They also offer educational resources such as guides and tools relevant to urban tree management and reforestation.
