In course of agro product, inputs which in the form of material, tekno¬logi, elements and menejemen of agro ecology will be processed to yield outputs which in the form of crop pickings and livestock. Peripheral pickings and waste of the production process can in the form of result of sediment, result of water, and chemical bahan-ba¬han able to become environmental pencemar. This its waste [is] it[him] transported [by] out of system produce and generate the expense of effect and eksternal of eksternalitas ( Soemarno, 1990). Usually agro product system [in] river headwaters of mempu¬nyai effect of eksternal which enough wide [of] and will be suffered by society [in] area under. In a[n drainage basin having irrigating building like bendung¬an, accumulating basin and irrigation network, effect of eksternalitas the become serious progressively, because can menace continuity of buildings.

Various effort have been [done/conducted] to control effect of eksternalitas, but its result still not yet is adequate. This matter because of because market mechanism cannot work for allocation of eksternalitas ( Soemarno, 1990). So that agriculture producer [in] headwaters do not want to account the expense of eksternal which its its[his]. Beside that, expense of to control effect of eksternalitas the relative compared to big sa¬ngat [of] production cost and acceptance of usahatani. In kon¬disi like this needed [by] interference policy of government. Davies and of Kamien ( 1972) telling bebera¬pa kinds of governmental interference for the mengendali¬kan of effect of eksternalitas, that is:

: ( i) the prohibition order,

: ( guidance ii),

: ( iii) activity of sample,

: ( Iease iv) or subsidy,

: ( arrangement v) ( regulasi),

: ( vi) fine or penalization, and.

: ( security action vii)
