In the Luangwa Valley, Zambia, persistent poverty and hunger present linked challenges to rural development and biodiversity conservation. Both household coping strategies and larger-scale economic development efforts have caused severe natural resource degradation that limits future economic opportunities and endangers ecosystem services. A model based on a business infrastructure has been developed to promote and maintain sustainable agricultural and natural resource management practices, leading to direct and indirect conservation outcomes. The Community Markets for Conservation (COMACO) model operates primarily with communities surrounding national parks, strengthening conservation benefits produced by these protected areas. COMACO first identifies the least food-secure households and trains them in sustainable agricultural practices that minimize threats to natural resources while meeting household needs. In addition, COMACO identifies people responsible for severe natural resource depletion and trains them to generate alternative income sources. In an effort to maintain compliance with these practices, COMACO provides extension support and access to high-value markets that would otherwise be inaccessible to participants. Because the model is continually evolving via adaptive management, success or failure of the model as a whole is difficult to quantify at this early stage. We therefore test specific hypotheses and present data documenting the stabilization of previously declining wildlife populations; the meeting of thresholds of productivity that give COMACO access to stable, high-value markets and progress toward economic self-sufficiency; and the adoption of sustainable agricultural practices by participants and other community members. Together, these findings describe a unique, business-oriented model for poverty alleviation, food production, and biodiversity conservation.conservation farming | food security | poaching | carbon | sustainability T he Luangwa Valley exhibits many characteristic linkages between poverty traps and risks to biodiversity. There is heavy reliance of households (HHs) on limited natural resources, shared vulnerability to yearly climatic variability, an absence of strong social/economic institutions, and unintended negative consequences of economic development efforts. The situation has been heading toward a new equilibrium impoverished in both human condition and biodiversity. Positive feedback stemming from trophic disruptions to wildlife populations and habitat, relatively recent shocks such as HIV/AIDS or fluctuations in cotton markets, and the continual shock of variations in rainfall all serve to hasten this change. Given the severity of these interrelated problems, a unique approach has been implemented to preserve biodiversity by focusing on improving livelihoods and food security. The Community Markets for Conservation (COMACO) model uses markets and an adaptive business approach to promote sustainable agricultural practices, rather than base development on natural re...

This paper provides a selective overview of the linkages and complementary topics in behavioral economics and agricultural adoption literatures. The goal of the paper is to identify likely directions for future research at the intersection of behavioral economics and agricultural adoption. This research agenda has potential for providing valuable insight for policymakers, researchers, and stakeholders in agriculture and beyond.

Many technology adoption decisions are made under uncertainty about the costs or benefits of subsequent investments in the technology after the initial take-up. As new information is realized, agents may prefer to abandon a technology that appeared profitable at the time of take-up. Low rates of follow-through (engagement in subsequent investments) are particularly problematic when subsidies are used to increase adoption, in part because they may attract users with a lower value for the technology. We use a field experiment with two stages of randomization to generate exogenous variation in the payoffs associated with taking up and following through with a new technology: a tree species that provides private fertilizer benefits to adopting farmers. Our empirical results show high rates of abandoning the technology, even after paying a positive price to take it up. The experimental variation offers a novel source of identification for a structural model of intertemporal decision making under uncertainty. Estimation results indicate that the farmers experience idiosyncratic shocks to net payoffs after take-up, which increase take-up but lower average per farmer tree survival. We simulate counterfactual outcomes under different levels of uncertainty and observe that subsidizing take-up of the technology affects the composition of adopters only when the level of uncertainty is relatively low. Thus, uncertainty provides an additional explanation for why many subsidized technologies may not be utilized even when take-up is high.

Technology adoption often requires multiple stages of investment. As new information emerges, agents may abandon a technology that was profitable in expectation. We use a field experiment to vary the payoffs at two stages of investment in a new technology: a tree species that provides on-farm fertilizer benefits. Farmer decisions identify the information about profitability that arrives between the take-up and follow-through stages. Results show that this form of uncertainty increases take-up but lowers average tree survival, decreasing the cost-effectiveness of take-up subsidies. Thus, uncertainty offers another explanation for why even costly technologies may go unused or be abandoned.
