Is soil science in an upswing?

In many countries, soil science has been traditionally associated with agriculture because of the major function of soil as a medium for plant growth. So it was no surprise that the decline in funding for agricultural research worldwide in the last two decades had taken its toll on student enrolment in agricultural sciences including soil science. But there are good signs that soil science is now experiencing an upswing particularly because of its strong link to environmental management and global warming (soil is a major source and sink of carbon) and to recent increased focus on agriculture.

In a recent paper published in Geoderma, Dr. Alfred E. Hartemink of ISRIC in Wageningen, Netherlands, and Prof. Alex McBratney (University of Sydney) think that soil science renaissance (from French word meaning "rebirth") is currentyl taking place "where novel approaches to thought are combined with a revival of ideas from the past." They noted that renewed interest in food, feed, and fuel production and the publication of numerous reports have brought soils back onto the global research agenda.

Recent reports by the United Nations and other international organizations have highlighted the need for up-to-date and fine resolution soil information and the revival of soil research. They cited as examples of key issues that have been discussed in recent publications soil erosion, nutrient depletion, and pollution particularly in relation to environmental degradation, climate change, and world food production. They estimated that about 3.2 billion euro is spent yearly on soil research worldwide. They urge the soil science community to benefit from the current upsurge in soil science.

Tropical soils: some important aspects of these less understood soils

Image
Tropical regions occur between the Tropic of Cancer and the Tropic of Capricorn. The tropics include approximately 40% of the land surface and is the largest ecozone of the earth. According to Köppen (1931), the tropics are characterized by an annual mean air temperature above 18°C through­out the whole year. The largest climatic variation is introduced by the variability of precipita­tion, reaching from nearly 0 mm in the Saharan and Atacama Desert to 11,700 mm on Mt. Waialeala in Hawaii (Eswaran et al., 1992). An Afisol (Luvisol) soil derived from mudstone in Eastern Samar, Philippines According to Uehara and Gillman  (1981), "t ropical soils" is a common name used to identify any soil that occurs in the tropics. They noted that like most common names, the term lacks precision, but it is more readily understood by a larger audience than are the scientific names. In contrast, Sanchez (1976) argued against the use of the term "tropical soils" since it does not accur

The causes of the Guinsaugon landslide

Image
On 17 February 2006, a catastrophic landslide buried the village of Guinsaugon, the second largest village of St. Bernard town (Southern Leyte, Philippines) killing more than a thousand residents and displacing approximately 19,000 people. The landslide originated on an approximately 800 m high escarpment produced by the Philippine Fault that bisects Leyte and the major islands of the Philippines. In a recent article which synthesized the papers presented during an international conference in Leyte 2008 and published in the international journal Bulletin of Engineering Geology and the Environment, Guthrie and co-workers (2009) arrived at the following conclusions: "The approximately 15 million m3 landslide was a result of progressive failures and tectonic weakening in a region made especially vulnerable by the inter-reaction of geological/tectonic, climatic and cultural factors. In southern Leyte, geology and tectonics (including historical seismicity, the progressive disintegr
