There are numerous reasons why landusers do not always adopt innovations. F
or different landuse enterprises and for different innovations, different c
onstraints will apply and these can be organised into three broad categorie
s. The first is characterised by the landuser and the adoption process. The
second emphasises the characteristics of the innovation itself and issues
associated with the developers of the innovation. The third area deals with
the role of extension agents and the transfer process. It is apparent that
technology transfer and adoption in sustainable landuse is largely being l
ed by commercial organisations. Landusers are being recognised as key stake
holders in both the adoption and technology development processes. Furtherm
ore, community groups and a range of government and NGOs are becoming invol
ved as major stakeholders in the transfer and adoption of sustainable landu
se practices. The study, however, reveals a shortage of data on the effecti
veness of corporations and other commercial organisations on the technology
transfer and adoption processes. Future research is needed on the followin
g: understanding the effectiveness of group-based approaches to technology
transfer and adoption; determining and predicting rates of adoption of sust
ainable practices; the ongoing effectiveness of different forms of media; e
valuating existing efforts of technology transfer and adoption particularly
related to land management practices; and understanding the constraints to
adoption associated with an aging landusing population. (C) 2000 Elsevier
