“…Much attention has being paid to find alternative options for shifting cultivation, including the total abandonment of forest plots, the adoption of productivity increasing green revolution-type technologies, the application of modern ''evergreen'' agroforestry knowledge (Palm et al 2005), and the intensification of land use by improving technical efficiency in farming (Pascual 2005). Research suggests that the adoption of such technologies by farmers is costly in terms of the labor investment (Ramirez and Shultz 2001), and largely depends on factors as diverse as land resources, and the wider institutional, economic, and techno-political context (Bellon and Taylor 1993). Findings from this article suggest that the strengthening of local ecological knowledge could be another option to reduce the area cleared under shifting agriculture through its interaction with agricultural labor.…”

Research on the benefits of local ecological knowledge for conservation lacks empirical data on the pathways through which local knowledge might affect natural resources management. We test whether ethnobotanical skills, a proxy for local ecological knowledge, are associated to the clearance of forest through their interaction with agricultural labor. We collected information from men in a society of gatherers-horticulturalist, the Tsimane' (Bolivia). Data included a baseline survey, a survey of ethnobotanical skills (n = 190 men), and two surveys on agricultural labor inputs (n = 466 plots). We find a direct effect of ethnobotanical skills in lowering the extent of forest cleared in fallow but not in old-growth forest. We also find that the interaction between ethnobotanical skills and labor invested in shifting cultivation has opposite effects depending on whether the clearing is done in oldgrowth or fallow forest. We explain the finding in the context of Tsimane' increasing integration to the market economy.

“…Since the response variables are all positive integers, we can assumed this follows the Poisson process (Cameron and Trivedi 2005;Greene 2011) and can thus be modelled using the basic Poisson model. In the literature, this model has been used to explain the adoption of agricultural and natural-resource management (Ramirez and Shultz 2000), the intensity of adoption of conservation agriculture (Pedzisa et al 2015), and soil-and water-conservation practices (Nkegbe and Shankar 2014).…”

Can Social Capital influence Smallholder Farmers’ Climate-Change Adaptation Decisions? Evidence from Three Semi-Arid Communities in Burkina Faso, West Africa

This study examines the influence of farmers' social capital on their decisions to deal with climate change and climate variability in Burkina Faso. The study is based on a household survey conducted among 450 households, randomly selected from three communities in Burkina Faso. Two indexes were constructed to capture farmers' structural and cognitive social capital; and using generalized Poisson regression (GPR) and a multivariate probit model, the study probes the effect of farmers' social capital on their choice of adaptation alternatives, the number of adaptation practices used, and the extent to which adaptation measures were applied. The results indicated that the effect of social capital depends on the type of indicator used and on the type of adaptation strategies necessary. Farmers' cognitive social capital was significantly and positively related to their choice of soil and water conservation techniques (SWCT), and techniques such as agroforestry and irrigation. Structural social capital, on the other hand, was positively associated with the adoption of new varieties and conservation tillage strategies and negatively associated with the use of a crop-diversification strategy. The results also highlighted that socio-economic, institutional and agro-ecological variables determine farmers' decisions to adapt to climate change.

“…Both of these options rely on univariate probit or logit models. A third approach is to use Poisson count models to explain the number of technologies firms adopt (Ramírez and Shultz 2000). All three approaches have drawbacks.…”

In many developing country cities, clusters of small and medium enterprises create severe pollution problems. Because conventional regulatory approaches are typically ineffective in such situations, policy responses have increasingly focused on promoting voluntary clean technological change. Yet the data and analysis needed to guide such efforts are scarce. This paper uses original firm-level survey data on a cluster of small-and medium-scale leather tanneries in León, Guanajuato -Mexico's leather capital-to econometrically identify the factors that drive the adoption of two clean tanning technologies. Using a multivariate probit model to estimate a system of seemingly unrelated regressions, we find-in contrast to conventional wisdom-that neither firm size nor regulatory pressure is positively correlated with adoption. Rather, the key driver of adoption is the firm's human capital, the same factor that often explains conventional productivity-enhancing technological change. We also find that a private-sector trade association is an important sources of technical information about clean technologies.
