It is shown that if ,u(x,t) , is a solution of the initial value problem\nfor the Camassa-Holm equation which vanishes in an open set ,\Ω\⊂\n mathbb R\× [0,T], then ,u(x,t)=0, ,(x,t)\∈ mathbb R\× [0,T]. This\nresult also applies to solutions of the initial periodic boundary value\nproblems associated to the Camassa-Holm equation. The argument of proof can be\nplaced in a general setting to extend the above results to a class of\nnon-linear non-local 1-dimensional models which includes the Degasperis-Procesi\nequation.\n
