This research examined livestock farmers' intention to move manure waste to an allocated landfill and the impact of financial support by municipalities on farmer's behaviour. The theoretical framework was developed using the Theory of Planned Behaviour and tested the validity of the model. The survey was carried out with 336 farmers in Bursa, Turkey, where animal husbandry is the primary livelihood source. Research results have shown that the developed model proved to be satisfactory in predicting farmers' intentions. The attitude (beta=0.38; p<0.01) variable was the most important determining factor on farmer behaviour, followed by subjective norms (beta=0.30; p<0.01). Local governments' financial support was a strong mediator effect between attitude (beta=0.62; p<0.01) and farmers' behaviour. This study emphasizes that local governments should employ more proactive environmental measures, raise financial support initiatives in animal waste management to ensure farmers' participation in these practices and sustainable agriculture.
