“…Our scope encompasses all academic peer-reviewed literature on studies quantifying the impacts of and returns to public expenditures in or for agriculture. 2 These are consistent with earlier meta-analyses (Alston et al, 2000a(Alston et al, , 2000bEvenson, 2001) as well as a more recent review (Alston, 2010) of the returns to public investments in agricultural research, development and extension, which show that internal rates of return are substantial. Recent country-level studies support the findings of the comprehensive reviews (Beninet al, 2011; Suphannachart and Warr 2011).…”

Within a policy environment of greater attention to agriculture following the food price crises in developing countries, this Special Issue is motivated by the importance of bringing to bear new conceptual and empirical research on the determinants, trends and consequences of public expenditures in support of the agricultural sector of developing economies. This introductory article lays the groundwork by first conceptually articulating the rationale for agricultural public investments. The articles in this Special Issue add to past literature in three main ways. First, careful analysis of newly compiled data provides new information on the patterns of agricultural public expenditures across developing regions. Second, the papers provide new insights on the cross-sectoral effects of different types of public spending and their complementarities and substitutability. And third, venturing into the examination of the political economy determinants of agricultural public expenditures opens the door to an important area of sparse research.Dans un environnement politique qui accorde une plus grande attention à l'agriculture, suite aux crises des prix des denrées alimentaires dans les pays en développement, ce numéro spécial est motivé par l'importance de mettre à profit les nouvelles recherches théoriques et empiriques sur les déterminants, les tendances, et les conséquences des dépenses publiques en faveur du secteur agricole dans les pays en développement. Cet article introductif jette les bases en exposant, de façon théorique pour commencer, le raisonnement qui sous-tend les investissements publics agricoles. Les articles de ce numéro spécial viennent s'ajouter au corps d'études existantes de trois façons principales: d'abord, une analyse minutieuse des données nouvellement compilées fournit de nouvelles informations sur les schémas de dépenses publiques agricoles dans toutes les régions en développement. Deuxièmement, les études fournissent de nouveaux aperçus sur les effets intersectoriels des différents types de dépenses publiques, sur leur complémentarité et sur leur substituabilité. Et troisièmement, s'aventurer dans l'exploration des déterminants de l'économie politique de dépenses publiques agricoles ouvre la porte à un domaine de recherche important et bien peu exploré.

“…Agricultural extension agents focus on imparting key messages to farmers with the aim of improving production techniques including land preparation, use of improved crop varieties, crop spacing as well as the timeliness of operations such as weeding, pest control and fertilizer application. According to Evenson (2001) and Gautam (2000), a well-functioning agricultural extension system is pivotal to increasing the productivity of staple food crops and thus presents a credible avenue for moving millions of people out of poverty. The World Development Report (World Bank, 2008) further emphasized the importance of agricultural extension service in the dissemination of technologies adapted to African conditions so as to spur an African green revolution if it is given the necessary institutional support.…”

Abstract-Agricultural research and extension programs have been built in most of the world's economies because agricultural science and technology innovation is the source to push agricultural development. Since 2004 China has increased gradually agricultural research investment, which promoted agriculture to develop rapidly. However, China's agricultural research investment has been lagging behind that of developed countries in proportion of investment or benefit of agricultural programs. In this paper, the factors affecting the Benefit of Agricultural research programs are been studied by Principal component analysis. It showed that research management and production factors are majors factors that impacting benefit of agricultural programs. So, the government should build scientific management system of agricultural programs and improve subsidiarity production factors to ensure the benefits of agricultural research projects could be effectively.
