In addition to its economic viability, small-scale aquaculture is usually more environmentally friendly compared to industrial production systems based on industrialized feeds. Fish feed usually includes a certain ratio of fishmeal and fish oil and these ingredients are produced mainly from small pelagic fish from capture fisheries, which put an additional burden on the marine environment. It also affects the food insecure population because small pelagic fish are highly nutritious and help to combat food and nutrition insecurity directly. Fish feed also includes agricultural products like corn and soya, thus competing with food production for human consumption. Despite the negative externalities on ocean biodiversity, research has also shown that intensive aquaculture systems contribute more to global warming through automated processes and high demand for production inputs. Additionally, these systems cause habitat destruction and introduce alien species, which further affect the indigenous biodiversity. In contrast, extensive and semi-intensive small-scale aquacultures requires little external inputs and have less environmental impact. For this reason, GP Fish supports small-scale aquaculture farming of omnivorous fish species such as Carp and Tilapia. The aim is to empower producers technically and economically by optimizing pond productivity and integrating fish production into agriculture activities. This approach uses the natural environment sustainably to promote fish production.

This block focuses on the support and incentive structure for participants. It includes providing seedlings, technical advice, and capacity-building. Payments are performance-based, tied to tree survival and the presence of indigenous and long-rotation species, encouraging long-term forest establishment.

Sensor alert system will be activated after sensor installation and software platform development phase till the end of data collection phase. A trial-based action response plan for each type of sensor is listed below. For long run, an action response plan will be developed through fine tuning after the completion of review and evaluation of IoT system phase. 

Hack The Planet acknowledge that our partnerships allow us to combine strengths, resources, and expertise, amplifying the impact and fostering innovative solutions. Collaborating creates shared value and builds networks, enabling mutual growth and sustainability.

Scanneredge is a collaboration with Tech for Conservation organisation Smartparks, Management of national parks like Gonarezhou - Zimbabwe, park technicians, rangers(QRU) and the local community. Through this cross-sector partnership, we have demonstrated that ScannerEdge is ready for broader deployment, increasing the number of active national parks and total scanners in use.

Leveraging real-time alerts from ScannerEdge, a response unit can quickly assess and mitigate potential threats, such as poaching or other illegal activities.

Inclusive and participatory mapping of all stakeholders in the mangrove space in the five counties of Kwale, Mombasa, Kilifi, Tana River and Lamu. A series of meetings for sensitization on the National Mangrove Management Plan, and later facilitated formation of the national and five county committees. The committees were then facilitated in developing their workplans and executing some of the activities. This has since been picked up. 

The debriefing occurs both during and after the game. Brief debriefs can take place after each session to gauge participants’ feelings about the game at individual and territorial levels. These are kept light to maintain the game’s flow.

Once the game is over, a more in-depth debriefing can take place. It doesn’t necessarily have to happen immediately after the game; it could be scheduled for the following day. Some preparation is required for this discussion. The facilitator should bring a list of prepared questions and a printed map of the territory. During this debriefing, participants will identify the challenges they faced regarding land use, as well as the causes of those challenges. Key actors needed for resolution and potential solution ideas will also be discussed. The map serves as a visual aid to guide the discussion. Some basic questions that could be asked include:

• What happened during the game? How much, how quickly, and why did the soil degrade?
• What were the main conflicts that arose during the game? Between which actors?
• Did you find any solutions?
• Did you try to implement them? What was the outcome?

Of course, the questions can be more specific and adapted to the participants and the situations that arose during the game. 

Early warning messages are primarily distributed through channels such as the early warning app, intelligent broadcasting, phone calls, and SMS. Among these, the early warning app is the most widely used method, covering the largest population. Monitoring personnel can also share messages from the app to WeChat groups or personal networks, enabling multiple rounds of dissemination and further extending the reach of early warnings. Expanding the user base of the early warning app is therefore critical. To maximize coverage among residents in elephant-affected areas, the monitoring teams have conducted in-village promotional campaigns to encourage app adoption. As of now, the early warning app has been downloaded by 246,661 users.

Our modular drones are designed for accessibility, adaptability, and sustainability. Initially crafted using wooden components with fewer than six screws and zip ties, they are simple to assemble, repair, and replicate using local materials, empowering communities to lead restoration projects independently.

As we’ve advanced, we’ve integrated hydrogen fuel cells and hybrid-electric propulsion systems, enhancing flight endurance, energy efficiency, and environmental sustainability. These innovations enable drones to cover larger areas and operate in remote environments while reducing their carbon footprint.

The modular design ensures flexibility for continuous adaptation, allowing communities to upgrade drones with tools like cameras or sensors for monitoring. This approach combines simplicity and cutting-edge innovation, bridging grassroots empowerment with scalable, impactful environmental restoration.

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)
