Measuring the initial state of fish stocks and regulations will likely highlight imbalances between fish availability and the licensing landscape. Low proportions of legally operating fishers emphasize the need for training to encourage legal fishing practices. The training content includes information on harmful fishing practices, such as the use of fine-meshed mosquito nets or poison. Additionally, the benefits of fisheries management are explained, which promotes the long-term stabilization of fish populations through sustainable fishing methods. To address the causes of IUU fishing, the training should consider the viewpoints and perspectives of fishers, as IUU practices in artisanal fishing often result from a lack of access to appropriate gear: what is needed to resort to legal fishing? This might include adapted regulations or the availability of appropriate fishing gear.

What strategies need to be pursued to make more fish available to consumers in local markets? Because wild fish stocks are generally overfished, and the oceans’ ecosystems experience severe degradation the logical strategy is to increase fish supply through aquaculture. When increasing fish availability, especially for the food insecure population, the approach chosen must be environmentally sustainable, provide fish at an affordable price for this group (e.g., by avoiding additional costs such as for transportation) and should still offer the opportunity for producers to earn a living income.

The approach should therefore be centered around sustainable, decentralized aquaculture adapted to the limited financial and technical capacities of smallholders. Small-scale aquaculture in low-income countries plays already a crucial role in food and nutrition security as well as poverty reduction but still has significant potential to grow. On the one hand, vertically integrated aquaculture farms (companies that expand production to up- or downstream supply-chain activities) make important contributions to a country’s economic growth by increasing export earnings, but they usually have only little impact on the local fish supply and food security. On the other hand, small-scale aquaculture directly contributes to a higher fish consumption by the producers, depending on cultural preference for fish as a source of animal protein and to higher incomes that allow producers to purchase other foods.

When evaluating aquaculture as a source of income, it is important to consider that most small-scale farmers have little technical knowledge and financial capacities. These constraints prevent them from making larger investments for infrastructure and inputs, which are required when operating an intensive aquaculture production system. Formulated feeds, veterinarian products and machinery can significantly increase aquaculture production but are in most cases financially prohibitive for smallholders in remote rural areas. The required investments exceed their financial capacities by far and credits would put the household economies at risk. For this reason, technical and financial capacity development is so important. Optimizing the productivity of earthen ponds with low investments for fertilizer and supplementary feeds generating high profits per kg fish produced seems a workable way forward.

As an example, for a technique increasing production and being adapted to smallholders’ capacities, the GP Fish has introduced intermittent harvesting of Tilapia in Malawi. This practice is applied in mixed sex cultures of Tilapia, based on natural feed supplemented with agricultural by-products. Excess Tilapias, that hatched during the production cycle, are harvested by size-selective traps before reaching reproductive age. These frequently harvested fish are an easy-accessible protein source and nutrient-rich food component for a diversified diet and surplus production is generating additional income. Intermittent harvesting also reduces the economic risk of losing the entire production due to predators, theft, diseases, or natural disasters.

The project strategically allocated land for agricultural and conservation purposes to balance human and wildlife needs. This comprehensive planning ensured sustainable land use that supported both community livelihoods and wildlife conservation. Farmers cultivated their lands using the skills from Climate-Smart Agriculture (CSA) training, resulting in improved harvests with zero threats from elephants and other wildlife, making the 10% fence plans 100% effective. The remaining 90% of the land was used as fallow for wildlife and farmers' livestock, bringing a sense of wildlife-livestock integration. All farmers received dam liners for water pans and collected water for livestock and farming. This model brought a sense of integrated land use with a win-win benefit for both wildlife and communities. Sustainable practices were promoted, and policy support was advocated to back the integrated land use plans legally and institutionally. Continuous monitoring and evaluation systems were implemented to adapt and improve the plans over time.

The project trained farmers in climate-smart agriculture (CSA) and permaculture farming practices to improve yields and sustainability. This involved practical training sessions, demonstration plots, and ongoing support to help farmers adopt and sustain new practices. Training programs were developed and delivered on CSA techniques, including soil conservation, water management, and sustainable crop choices.

Farmers were trained by experts from the Kenya Agricultural and Livestock Research Organization (KALRO), with a deep concentration on dry crop farming such as cowpeas, green grams, millet, and cassava. They were also linked to KALRO for the procurement of certified seeds for planting. The training was conducted before the onset of the long rains season, allowing farmers to apply the skills garnered just in time for planting before the rains started. County Agriculture officers attended the sessions to drum up support from the government.

Demonstration farms were established within the community to showcase best practices and allow farmers to see the benefits firsthand. Support networks and farmer groups were created for sharing knowledge, resources, and experiences, fostering peer learning and support. Necessary resources such as seeds, tools, and organic fertilizers were provided to help farmers implement new techniques.

Electrified "porcupine fences" were installed around 10% of each of the three land plots identified to protect households, crops and property from wildlife. These fences were designed to prevent large wildlife, particularly elephants, from entering 10% protected areas, thereby reducing human-wildlife conflict. Construction began in March 2023, with three plots (totaling 10 acres) being constructed. The fence construction was completed by mid-April 2023, securing over 20 people in the three households. During construction, all casual workers were youths from the Kamungi Conservancy Community, providing an indirect benefit of income and honing skills in fence construction and maintenance. This ensured that knowledge was retained within Kamungi for future maintenance. Skilled technicians oversaw the construction and maintenance of the fences, ensuring they were built to withstand wildlife pressures. Community members were actively involved in the construction process to reduce costs and foster a sense of ownership.

On-station trials

In a series of experiments conducted at the National Aquaculture Center in Domasi, the project team tested the trap for intermittent harvest with different baits in ponds (200 m2) stocked with different species (Coptodon Rendalli vs. Oreochromis Shiranus) at different densities (1 vs. 2 vs. 3 fish per sqm.). In addition, further tests were carried out to determine the time and intervals it takes to catch a certain amount of fish. As a control and for comparison, additional ponds were stocked with O. Shiranus and C. Rendalli fed with maize bran or pellets for single batch harvest to represent customary forms of rural aquaculture in Malawi.

On-farm trials

At the time when the trap was technically functional, households that wanted to test the trap under every day, real-life conditions were identified. Over three months, six households tested the trap and documented the catch.

The trap is made from wire mesh and shaped like a cylinder. Two additional wire mesh pieces shaped like a cone are attached at both ends. The diameter of the narrower end is kept smaller to allow only small fish to enter the trap. To lure them in, bait is placed inside. A piece of a net holds the bait. A string is fixed to the trap so that users can easily sink and retrieve the trap.

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.
