Adamorobe Sign Language (AdaSL), Ghana, is an old village sign language used by 33 deaf people. Langue des Signes de Bouakako (LaSiBo), Côte d'Ivoire, is new and used by six deaf people in a village. Língua Gestual Guineense, Guinea-Bissau, is an emerging school-based sign language used by around 500 deaf people.

GGC (Gildas) Assogba: The overall objective of my PHD was to improve food security in semi-arid Burkina Faso through better crop and livestock integration and production. To reach my objective, I developed with farmers several co-learning and co-design tools including: farm monitoring forms, serious games and models. The combination of these tools allowed a participatory description and exploration of the farming system. I showed that the current farming system management was only optimal to guarantee short-term food security considering farmers’ livelihoods and resources (e.g. cropland and grazing areas) available in their environment.
