Can Invasive Plants Improve Drought Resilience? A Participatory Approach in Northern Nigeria

Abstract

Innovative solutions are needed to fight against the expansion of invasive species worldwide. In Hadejia Valley, in northern Nigeria, cattail (Typha spp.) has colonized vast areas causing environmental and food security problems. Livestock plays a key role in ensuring food security in this region; however, it becomes compromised during the dry season. A nature-based solution is proposed that takes advantage of the invasive plant species to produce silage. To facilitate the adoption of this technology, we employ a participatory approach in which fuzzy cognitive maps are used to enhance adaptation to local conditions and future implementation. We perform focus groups and face-to-face interviews with 312 people. The participants demonstrated a strong willingness to adopt the technology, and our findings indicate positive gender-related impacts on business opportunities. However, we also identify barriers that could be addressed by taking advantage of the social capital in the region and implementing targeted economic subsidies.
