Summary: We characterize, in terms of the Young measures of the sequence $$a_\varepsilon$$, the weak sequential $$\Gamma$$-limit of the functionals $$J_\varepsilon (v)$$, associated to the nonlinear equation $\partial_t u_\varepsilon (t,x)+ a_\varepsilon (x)g \bigl( u_\varepsilon (t,x)\bigr) = f,\quad u_\varepsilon (0,x)=u_0.$ The non-additivity of the limit functional $$J(v)$$ may be seen as a consequence of the nonlocal effect, similar to the one that occurs in the linear case.
