Why Agriculture Productivity Falls: The Political Economy of Agrarian Transition in Developing Countries offers a new explanation for the decline in agricultural productivity in developing countries. Transcending the conventional approaches to understanding productivity using agricultural inputs and factors of production, this work brings in the role of formal and informal institutions that govern transactions, property rights, and accumulation. This more robust methodology leads to a comprehensive, well-balanced lens to perceive agrarian transition in developing countries. It argues that the existing process of accumulation has resulted in nonsustainable agriculture because of market failures—the result of asymmetries of power, diseconomies of scale, …

Invasion paradox, a change of direction in native-exotic richness relationships (NERRs) from negative at small scales to positive at large scales, has been shown to exist in many environments. A major explanation for these patterns is environmental heterogeneity, and to a lesser extent, species pool size. It is likely that a combination of these factors is producing these patterns and determines if and how they appear in certain environments. Beta diversity, which describes the heterogeneity of species composition among assemblages and as the scalar between local richness and regional richness (species pool size), could serve as a proxy for these …
