Effects of agricultural mechanization on economies of scope in crop production in Nigeria by Takeshima, Hiroyuki, Hatzenbuehler, Patrick L., Edeh, Hyacinth O.

“…Mechanical technologies may raise EOS between crops that are grown in more heterogeneous environments, even though it may lower EOS between crops that are grown under relatively similar agroecological conditions. To the best of our knowledge, this is the first paper that shows the effects of mechanical technologies on EOS in agriculture in developing countries.…”

Pathways of rural development in Madagascar: an empirical investigation of the critical triangle of environmental sustainability, economic growth, and poverty alleviation by Zeller, Manfred, Lapenu, Cecile, Minten, Bart, Ralison, Eliane, Randrianaivo, Desire, Randrianarisoa, Claude

“…These patterns are consistent with the wide-held belief that rural areas in Madagascar have witnessed increased poverty, economic stagnation, and a continued degradation of the natural resources. Yet, the five agroecological regions in our sample exhibit quite different patterns of rural development, and at least one of them has experienced increases in yields and wages. …”
