Agriculture plays a vital role in African countries, driving economic growth, employment, and non-agricultural sector improvements. However, persistent food insecurity and poverty among smallholder families raise concerns. Land fragmentation compounds these issues, limiting agricultural productivity and pushing farmers towards off-farm activities, despite Africa's potential agricultural markets. The study's focus is Donomadé, a remote village in southern Togo. This study pursues a dual objective. Firstly, it investigates how household characteristics, including family size and resource availability, influence farmers' resource management decisions. Secondly, the research employs serious games to comprehend farmers' livelihood strategy choices within constrained real-world-like conditions. The iterative and participatory Companion Modelling (ComMod) approach was utilized for the co-design and co-development of a serious game. This involved close collaboration with a local research team from the University of Lomé, a local NGO, and Donomadé village farmers. Various farming systems were characterized, and collective insights into Donomadé's agricultural dynamics were gathered through surveys, interviews, and workshops. Regardless of their in-game roles, farmers prioritize fulfilling basic family needs, such as food security and education instead of investing in agriculture. The study underscores the significance of household composition and resource availability when designing technology interventions or support mechanisms for farmers. Aligning interventions with farmers' overarching goals and challenges can enhance technology adoption. Furthermore, addressing food security remains crucial for sustainable development, as it not only improves human welfare and alleviates hunger but also forms the foundation for comprehensive solutions in the face of climate change, resource constraints, and population growth. This research highlights that heavy investment in agriculture is not the priority for many farmers in southern Togo, despite it being their main source of sustenance and income. Addressing immediate family needs, especially food security, education, and housing, takes precedence over long-term agricultural investments. Given the persistent challenge of food security amidst global uncertainties, addressing these priorities is paramount to stimulate more significant interest in agricultural investment.
