TL;DR: In this article, the authors present measures of land and labor productivity for a group of ninety-eight developed and developing countries using an entirely new data set with annual observations spanning the past three decades.

TL;DR: In the past three decades, Africa's public agricultural research systems have changed in substantive ways as mentioned in this paper, the total number of researchers increased fourfold, the dependency on expatriate researchers significantly declined, while the education levels of national researchers improved.

TL;DR: For much of the post-WWII period, governments in rich and poor countries alike have increased public spending on, and performance of, agricultural research as mentioned in this paper, focusing on the public and rapidly evolving, private roles in financing agricultural R&D, and the international dimensions of these funding and policy issues.

TL;DR: In this paper, the major policy dimensions of agricultural research, both national and international, with a primary focus on less developed countries, are explored. And the approach is strongly quantitative and presents a synthesis and interpretation of the data.

TL;DR: The authors identified 86 networks, of which 72 involved Africans linked to Africans, a rather parochial strategy in an increasingly interdependent world, a feature of much of the regions's research in earlier, colonial times, as described here.
