This paper analyzes the role of legitimization processes in the struggle ov
er farmland protection policies in Israel. In the early sixties a centraliz
ed farmland protection program was institutionalized, curtailing private la
nd owners' and leaseholders' property rights on farmlands. The legitimacy a
ccorded to such measures is explained as a function of the congruence betwe
en social norms, power structure and dominant ideology at the time. Then, t
he paper follows the changes in power, ideology, social norms, sanctioned d
iscourse and the role of agriculture in the economy. These changes undermin
ed the basis of the farmland protection rationales, and led to a crisis of
legitimacy in the early nineties. As a result of several institutional and
policy shifts in the early nineties, a time of rapid growth, concern shifte
d to the implications of growth for the future of open spaces. This concern
over the loss of positive externalities was shared by environmentalists, u
rban and exurban consumption interests. planners and several elements withi
n the rural establishment. As a result a new set of plans was introduced. F
ocusing on the central district; where the most severe development pressure
s are felt, the paper compares the sanctioned discourse and use of rational
es in the new- plans and documents to those of previous plans. These plans
focus on averting the loss of positive externalities, rather than productiv
e capacity, and are couched in economic terms, rather than ideological term
s, reflecting the shift in language of the sanctioned discourse. It shows t
hat the choice of rationales for legitimizing countryside conservation refl
ects the struggle over rural landscapes, as the rationales are used to cobb
le a coalition of planners, environmentalists, farmers. urbanites and exurb
anites, against a powerful development coalition. (C) 1999 Elsevier Science
