Implications of local policies and institutions on the adoption of improved fallows in eastern Zambia

Planted-tree fallows (syn. improved fallows) have demonstrated great biophysical potential for improving soil fertility on smallholders’ farms but efforts to scale up their adoption to more farming households are constrained by lack of permanent ownership rights over land, incidence of bush fires and browsing of tree biomass by livestock. To resolve these institutional bottlenecks, some traditional authorities in Zambia enacted bylaws to prohibit these incursions. Using a combination of village workshops, expert opinion surveys and structured questionnaires, this study assessed the effectiveness of the bylaws across the major cultural communities in eastern Zambia, identified factors that influence the effectiveness of the bylaws and the lessons emanating from the bylaws in the scaling up of improved fallows. The results indicate that fire poses greater risks to the scaling up of agroforestry than does grazing in terms of the risk of occurrence and the extent of damage. Respondents identified mice hunters and `jealous’ neighbors as main causes of fire outbreaks. The effectiveness of the bylaws is influenced by many factors such as ambiguous interpretation of the bylaws, relying exclusively on moral persuasion to enforce the bylaws and lack of well defined responsibilities for enforcing the bylaws, conflict of economic interests among different stakeholders within the communities. Formal documentation of the bylaws will be helpful, but that would not be an exclusive panacea to solve all the constraints. The pattern of distribution of benefits (or costs) of an agricultural technology among various sectors of a community may be important factors that affect widespread adoption of a technology. Technological characteristics are important but not exclusive condition for sustained widespread adoption of soil fertility management options. Privatizing seasonal commons is an important issue in the development of institutional regulations within communities. Policy dialogue among community members, increased awareness and diversification of options appear to be the way forward to improve the effectiveness of the bylaws.
