      The food status of the world today in relation to the existing population is skewed toward unfavorable balances and therefore food and environmental insecurity. These conditions are magnified in the tropics where natural calamities (drought, typhoons, flooding) appear to be more rampant than in temperate zones. Furthermore, the land suited for crop and animal production has nearly been fully utilized in much of the tropics so there is essentially nowhere to expand terrestrial agriculture. Therefore, the trend is to optimize productivity/unit area/unit time for existing farms. To achieve this goal, there is a need to fully understand the biogeochemical and physical environment of the crops to improve the current level of production. In its modest way, the book Basic Soil Science and Concepts in Tropical Soils written by Dr. Benjamin Mahilum for undergraduate students assists towards accomplishing this objective. It is our hope that it will also stimulate some to pursue careers in tropical soils research in order to better address enhanced food security and environmental quality in the tropics.

      Dr. Mahilum is a retired Professor of Soil Science and a former international agriculture consultant who presently resides on his diversified farm in Honokaʻa, Hawaiʻi. He was a faculty member in the College of Agriculture at the University of Hawai`i at Hilo from 1979 to 1986 and a University of Hawaiʻi at Hilo Affiliate Professor of Agronomy & Soils from 2004 to 2011. He also co-authored a book entitled Organic Compounds in Soils: Sorption, Degradation, and Persistence, Ann Arbor Science Press, 1982.
