Abstract Promoting Farmer Managed Natural Regeneration (FMNR) aims to increase the productive capacities of farmer households. Under FMNR, farmers select and manage natural regeneration on farmlands keep them under production. While FMNR contributes wealth farming communities, its contribution household food security has rarely been researched. We, therefore, used a mixed-methods approach address research gap by measuring FMNR’s among households in Talensi district Ghana. We adopted Household Dietary Diversity Score (HDDS) Food Consumption (FCS) estimate status 243 non-FMNR Also, we performed Chi-square test independence compare frequency each group (present vs not present) between adopters establish relationship adopting consuming FCS HDDS groups. Our results reveal that are more secure than The HHDS was 9.6, which is higher target value 9.1. Conversely, 4.3, lower Up 86% 37% fell within acceptable FCS; 15% 17% borderline FCS. none poor FCS, 46% Adopting significantly related all groups promoted benefiting from practices. paper recommends enabling semi-arid environments practice invest for long-term returns security.

Adoption by livestock producers of preventive non-lethal innovations forms a critical pathway towards human and large carnivore coexistence. However, it is impeded factors such as socio-cultural contexts, governing institutions, ‘perverse’ economic incentives that result in ‘lock-in’ lethal control carnivores grazing systems. In Australian rangelands, the dingo dominant predator conflict with ‘graziers’ subjected to measures despite evidence indicating its presence agricultural landscapes can provide multiple benefits. Here we explore barriers uptake through 21 in-depth interviews conducted graziers, researchers, conservation government representatives. Drawing on Donella Meadow’s leverage points for system change framework, focus, primarily, ‘political sphere’ because they appear form greatest impediment adoption tools practices. These are then discussed relation characteristics lock-in traps (self-reinforcement, persistence, path dependencies, undesirability) assess how constrain promotion human–dingo
