Social Campaigning
"Social campaigning (as distinct from campaigns used in warfare, politics or business) covers the very diverse practices used in civil society for advocating change to decision-makers - often through public mobilisations or the staging of popular demands, but also through less obvious processes of lobbying and elite organising. It plays a vital role in publicly identifying social problems, proposing ways of tackling them, staging competing claims for the good society, and encouraging association, volunteering and active citizenship."
