About 26% of the Indian population is deficient in calories and 28% in protein (Chand et al. 2003). The deficiency is most acute among the poor. The magnitude of micronutrient [iron (Fe) and zinc (Zn)] deficit is particularly alarming among children, women of reproductive age, and pregnant and lactating women (Sharma 2003). Current efforts to combat micronutrient malnutrition in the developing ...

Although regional climates throughout much of the world appear to have become more arid in late Cenozoic time, sedimentation rates, and therefore presumably erosion rates, have increased. For sustained erosion of elevated terrain, at least where glaciers are not the major erosive agent, rivers must incise. Therefore bed-load transport by rivers should be a rate-limiting process in erosion. Theo...

The Tropical Rainfall Measuring Mission (TRMM) and Global Precipitation (GPM) are the most important widely used data sources in several applications—e.g., forecasting drought flood, managing water resources—especially areas with sparse or no other robust sources. This study explored accuracy precision of satellite products over a span 18 years (2000–2017) using synoptic ground station for thre...

In most soils of the humid tropics, kaolinitic topsoil horizons overlie more gibbsitic horizons. This arrangement cannot be produced simply by leaching. Quantitative measurement of the turnover of chemical elements in the litterfall in an Amazonian ecosystem indicates that the forest cycles a significant amount of elements, particularly silicon. As a result, fluids that percolate through topsoi...
