We are pleased to announce that the 24th IHP Training Course on

Forest Hydrology - Conservation of Forest, Soil and Water Resources

Which will be held in Nagoya, Japan from 24 November to 7 December 2014.

UNESCO Office Jakarta, in collaboration with the School of Internet Asia and CONNECT-Asia, will provide e -learning opportunities by broadcasting the whole training courses in numerous video conference spots in the region. This option offers good connection equipped with Video Conference facilities for convenient lectures and interactive sessions.

If you are interested to follow the course through Video Conference, please register through the CONNECT-Asia website. We send you email to inform the nearest Video Conference spot to your location and the procedures.



A short training course "Forest Hydrology -Conservation of Forest, Soil and Water Resources" will be programmed for participants from Asia-Pacific regions as a part of the Japanese contribution to the International Hydrological Program (IHP). The course is composed of a series of lectures and practice sessions.


Incident rainwater is firstly intercepted by foliage and branches and evaporates from their surface to the atmosphere. Following interceptions by plant surfaces, the water is channeled along the plant body. Some of incident rainwater directly reaches the soils without touching foliage and branches. This rainwater infiltrates into the soils and is influenced by the soil pore structure, as it percolates to the groundwater table. Since soil water movement is slow, some of the soil water is absorbed by plant roots, where it is conducted through stem conduits, reaches leaves, and evaporates to the atmosphere through stomata. The groundwater flows to a river. This is an outline of water cycling in the forest ecosystems, and science on this water cycling is “Forest Hydrology”.

As one can see above, Forest Hydrology has two major scientific aspects: (1) discharge from forested watersheds; and (2) water use by trees (evaporation from the forest canopy). Soils in the forested watershed have a high hydraulic conductivity at the ground surface, which prevents soil erosion, and functions to make soil water flow slowly, resulting in a behavior like a dam. Rainfall subtracted by the forest water use denotes the upper limit of available water for the ecosystem including human use. This means that forest management, such as thinning and conversion of forest, can be expected to alter and enhance the forest’s abilities to prevent disasters and preserve water resources. These are the main practical applications of Forest Hydrology.

In this training course, the basics of forest hydrology and its application for conservation of forests, soil and water resources will be introduced. Its global scale implications will also be included. Practices are for understanding hydrological significance of forests and learning skills to manage forests so that managers may optimize their hydrological functions. As an important aspect, this training course will deal with the specific hydrological issues of East Asian countries. For example, many of the forest water use theories assume larger evaporative demand than annual precipitation and an evenly distributed precipitation throughout the year or large precipitation in winter. Scientists from the US and UK devised these theories for application to their familiar hydrologic environment. As such, there is a need for more detailed information of forest water use when precipitation is larger than evaporative demand and when there is greater precipitation in summer conditions, as in most East Asian countries, which would advance knowledge of forest hydrology both locally and globally.


Downloading the Textbook for Participants from the Website

The textbook of “the 24th IHP Training Course”, which is converted in PDF style, will be prepared and will be put on the IHP Nagoya/Kyoto forum website of “www.ihpnagoyaforum.org”. The participants are requested to download such a PDF file from the website in advance as a preparation to the several lectures of the training course. The textbook should be constituted of contents (referred sentence bodies, figures, tables, pictures, equations and observed/calculated results) with authorized copyrights.


The 23rd IHP Training Course is Finished!

The 23rd IHP Training Course on


was organized by the Water Resources Research Center, Disaster Prevention Research Institute of Kyoto University and Institute of Hydrospheric-Atmospheric Sciences of Nagoya University. The training course was held in Kyoto, Japan, from 2 to 13 December, 2013 and attended by 24 participants. The course included 2 keynotes and 9 lectures in English, technical field visit, and practice sessions.


The 23rd IHP training course is focused on three major objectives: (1) to acquire the latest knowledge on hydrological and ecological assessment under climate changes at river basin scale, (2) to make practice for learning the methodologies for assessing the impact of climate change on hydrological and ecological processes, and (3) to discuss the possibility to include the hydrological and ecological responses to climate change into the water resources managements.


All lectures in the 23rd IHP Training Course were also broadcasted through video conference and live streaming in collaboration with the CONNECT Asia and SOI Asia.
