This was especially due to the presence of a large glossoscolecid anecic species, Martiodrilus carimaguensis Jim\233nez and Moreno, which has been greatly favored by conversion of savanna to pasture. Endogeic species were dominant in the natural savanna whereas the anecic species accounted for the 88% of total earthworm biomass in the pasture. Total earthworm density and biomass were significantly different in the two systems studied (t-test).

A global estimate of the potential for rain-fed agriculture could provide an answer to the question "How much irrigation is required?" Global studies done to date have relied on course resolution climate data (0.5-1 degree arc). In this study a high-resolution climate dataset (10-minute arc) was combined with a soil water storage capacity map and a dynamic water and crop model to estimate the potential for rain-fed agriculture.
