Investments in irrigation together with farmers’ long experience on rice culture were major factors behind the success of the development and diffusion of MVs in tropical Asia (Hayami and Otsuka 1994). Yet major investments in irrigation took place after the acceleration in MV adoption indicating that MVs had increased the rates of returns to such investments (Fig. 2). In the early phase of GR, the expansion in irrigation system was in the form of large gravity irrigation systems financed mainly by international organizations (Herdt 2010), which was later replaced by privately owned portable shallow tube wells particularly common in South Asia (Hossain 2009).

4 briefly describes Asian GR in rice in terms of the evolution and spread of MVs, changes in irrigation, fertilizer use and trends in rice yield as well the subsequent changes in institutions and policies in Asia. 5 explores the sources of yield growth and describes the evolutionary processes underlying the GR in Central Luzon in the Philippines. 6 describes the current state of rice yield in SSA and the potential of transferring the Asian GR. Finally, Sect. 7 concludes this chapter. 2 Conceptual Framework and Hypotheses The whole evolutionary process of GR in Asia could be best described in a simple schematic diagram shown in Fig.

Our main argument is that the GR in Asia is essentially technology-led and policy-supported, rather than policy-driven as is oftentimes assumed (Djurfeldt et al. 2005). The development of MVs induced subsequent public-sector investments in extension and national research programs, irrigation, and credit programs by increasing the rates of returns to such investments (Fig. 1). Responding to profitable opportunities created by the new technologies, both factor and product markets gradually developed in Asia.
