Advocacy conducted by the Institute is bringing forward the small-scale producers to speak in their favour, recommends, argues for a cause, supports or defend their land rights. The Institute seeks to ensure that all people in the society can have their voices heard on issues that are important to them concerning land and to protect and promote their land rights. Have their views and wishes genuinely considered when decisions on land are being made. Advocacy has been designed to influence the opinions, policies and decisions to support sustainable land use management that responds to small producers' demands. This is so because the land is a socio-economic resource that is dependent on livelihood. To achieve this the advocacy aims at creating or changing policies, laws, regulations, decisions that affect small producers and to ensure that rights over land are accessible, definite and protected hence “pro-poor advocacy”

Generally, the advocacy is directed at policymakers including politicians, government officials and public servants, but also private sector leaders whose decisions impact upon small producers' lives, as well as those whose opinions and actions influence policymakers, such as the media, development agencies and likeminded non-government organizations. The Institute’s steps in conducting advocacy include but are not limited to the following researches; land and related natural resources law and policy analysis; dialogue and negotiations with policy markers; joint sessions with communities and policymakers; building partnerships and coalition/ alliance; building the advocacy capacity of like-minded organizations and communities; use of media; and monitoring and evaluation.
