| This paper contrasts the successful transformation of the oil palm sector in Malaysia with the stagnation of the oil palm sector in Nigeria, and examines the factors determining the different paths that the oil palm sectors took in these two countries with the aim of drawing lessons for future development and transfer strategy in Nigeria. Comparing two countries in different regions is not easy, especially when Nigeria has been in political chaos and the agro-climatic environments for oil-palm production differ greatly in these two countries. The purpose of this paper is, therefore, not to compare the potential technology frontiers these two countries can reach, but instead to highlight the technological and environmental factors that helped or hindered... |

| This paper investigates the impact of the dissemination of modern irrigation systems, i.e. private wells with pumps, on the livelihood not only among the farmers who have access to wells but also among the farmers who have no access to wells and thus rely solely on traditional irrigation systems called tank irrigation systems. The analysis is based on a village and household data set collected in Tamil Nadu, India where tank irrigation systems have been managed collectively for rice cultivation. Our statistical analyses predict that once declines in collective management occur due to the dissemination of private wells, the rice yield and income of the no-well-access farmers alone will decrease, resulting in increased poverty among them. Our analyses also... |

| Attention to organic fertilizer has been increasing but opinions are mixed as to its impacts. This paper explores the potential and limitations of the use of farmyard manure (FYM) for paddy and upland cereals under different soil conditions in Tamil Nadu, India, using farming households’ three-year rotating panel data from 1993 to 2003. Estimated yield functions reveal that a direct impact of FYM application exists only for upland cereals but not for paddy. Meanwhile, an indirect impact through an increase in the marginal product of chemical fertilizer is observed for both paddy and upland cereals, especially under low inherent soil fertility status. Reflecting the existence of the benefit of FYM application, our factor demand estimation shows that farmers... |

| It is widely believed that not only a Green Revolution in a crop sector but also a White Revolution in a dairy sector has generated the great momentum of agricultural development in India since the late 1960s. However, due to the dominance of sector-specific analyses, the importance of the interaction between these two sectors has been neglected in the existing literature. The interaction is important in that the dairy sector provides manure to crop production while the crop sector supplies fodder to the dairy. Using household data collected in Tamil Nadu, India for three decades from 1971, we show the increase of fodder production as a byproduct of Green Revolution in 1970s enabled subsequent White Revolution in 1980s and the byproduct of the White... |

| The purpose of this paper is to provide a conceptual framework that can be used by agricultural leaders, administrators, policy makers, and seed program managers to (1) understand key factors affecting seed system development; and (2) compare organizational and institutional strategies for increasing seed system effectiveness. A literature review of recent studies on seed system development in Sub-Saharan Africa (SSA) was undertaken to achieve these objectives. The studies reviewed included published and unpublished reports, monographs, and case studies. |
