Climate-smart agriculture (CSA) is a technologically innovative response to the challenges faced by agriculture due to climate change. Its implementation needs a change of mentality in the direction of an approach that takes into account how the increase in technologically induced productivity affects climate change. In the belief that the in-depth analysis conducted by scientific research plays a fundamental role, we explore the characteristics, actors, and pillars of CSA, examining both the scientific literature and financed projects. Specifically, through a systematic review of the literature we address both the application and barriers to implementation at a global level, and then we focus on a case study of the geographical distribution of CSA projects in Europe. Our results show a heterogeneous framework in which we can note discrepancies among countries. Finally, as conclusive remarks, we consider the type of policies that could be implemented to improve the diffusion of CSA in the near future.

This study deals with the debate that took place among Italian economists and statisticians at the turn of the twentieth century on the economic effects of mass emigration. In particular, it is focused on a controversy between Vilfredo Pareto and Alberto Beneduce on the one side, and Francesco Coletti on the other. It analyzes the way these scholars struggled with: (i) the problem of properly elaborating a specific cost-benefit analysis regarding emigration; and (ii), as a consequence, the problem of recognizing a clear set of economic policies designed to manage the complex economic and social processes connected to emigration. The paper demonstrates the enduring character of the problems encountered in the early Italian debates by showing that these questions are similar to those debated in the vast literature developed from the 1950s on the subject of brain drain, and suggests an explanation for the lack of conclusive results in this literature. We think that it is possible to understand this impasse by highlighting that in the analyzed literature, a problem of “fallacy of composition” emerges between the microeconomics and macroeconomics of emigration.
