Attempts to reduce land degradation by influencing the management beha
viour of farmers will be better informed when the relative importance
of factors influencing the use of 'conservation' practices aimed at en
hancing longer-term land productivity can be quantified Land managers'
perceptions of the technical feasibility and profitability of such pr
actices will play an important role in the decisions about their use.
Of particular interest is the relative importance of an individual's p
erceptions of the profitability of conservation behaviours and the ind
ividual's conservation orientation In a pretest-post test study the in
fluence of prior perceptions about two 'conservation' practices, and o
f environmental orientation on the subsequent behaviour of farmers is
investigated A logistic regression model is developed to show the rela
tive influence of perceptions of profitability and technical feasibili
ty and of personal environmental concern on the choice of conservation
practices. Perceived profitability was the most important factor infl
uencing the use of conservation practices.
