“…Apart from a technology's complexity, the heterogeneity of response to inputs, itself a potential important characteristic of a technology, may further complicate the social learning process (Munshi 2004). This could, for instance, explain slower diffusion in places with larger soil heterogeneity (Assunção et al 2014. A number of studies investigate how to optimize targeting in village economies starting from a better understanding of social network structures and find that the social identity of the communicator influences others' learning and adoption , Emerick 2018).…”

Farmers’ Demand and the Traits and Diffusion of Agricultural Innovations in Developing Countries

International agricultural research is often motivated by the potential benefits it could bring to smallholder farmers in developing countries. A recent experimental literature has emerged on why innovations resulting from such research, which often focuses on yield enhancement, fail to be adopted due to either external or internal constraints. This article reviews this literature, focusing on the traits of the different technologies and their complexity and distinguishing between yield-enhancing, variance-reducing, and water- or labor-reducing technologies. It also discusses how farmers’ reallocation of inputs and investments when external constraints are lifted suggests that they often do not seek to increase yield or input intensity. The article further reviews evidence indicating that a technology's potential as observed in agronomical trials is not necessarily a good predictor for smallholder farmers’ demands for the technology in real-life conditions. The last section derives conclusions for the research and policy agenda.

“…The practice of fluctuating between pasture and agricultural land use in Brazil is an established and documented technique, which is used by farmers to maintain the greatest gains from the land [45,85]. Newer and more sustainable techniques for cultivation, which result in less land degradation [86,87], and the increased profitability of agriculture compared to pasture lands [45,79,80,88] likely contributed to these land use changes. Additionally, of all the agricultural crops identified in the classification, sugarcane and soybeans are the most profitable [47].…”

“…In Brazil, sugarcane is an important agricultural product as a food product and a major source of ethanol alcohol, which has increasingly more uses including as a sustainable alternative fuel source. It is reported that conversion of cattle pasture and other land to cropland in Brazil is due not only to rising domestic and international food demand but also to rising ethanol production for fuel, food, and fibers, expanding demand for sugarcane [68,90], and was influenced by several government driven initiatives to increase engagement in sugarcane cultivation [64,79,88,91].…”

This study investigated the land use and land cover changes in the state of São Paulo, Brazil, for the period of 2002 through 2017, to determine if forested areas were burned or converted to other land uses, to analyze the use of fire as a catalyst and mechanism for land cover change, and to determine if there was a relationship between land use changes and gross domestic product (GDP). MapBiomas classifications and MODIS data were analyzed using the Google Earth Engine. The results of the analysis found that there were minimal changes in the forested areas in São Paulo during the study period; however, there was a 5% increase in natural forest and a 75% increase in planted forest cover. On the other hand, there was a 128% increase in sugarcane, and nearly a 50% decrease in pasture land coverage, suggesting that land was converted from pasture to more profitable agricultural land. Finally, there was a strong positive correlation (r = 0.96) between the increase in sugarcane and the GDP, and a negative correlation between the frequency of fire events and economic production (r = −0.62). Overall, there was a decline in fire events in São Paulo, with fire events occurring in less than 2% of the total observed land area by 2017. This overall declining trend in fire events are likely the direct result of increases in green harvest methods, which prevent the need for pre-harvest burning.
