About

What is ALTENA?
Asian Long-Term Experimental Network for Agricultural (ALTENA) is a research consortia consisting of individual scientists who are involved in agricultural long-term field experiments with a focus on soil or plant-soil interaction. ALTENA was launched on March 1st, 2017 by the scientists who participated in the NARO-MARCO international symposium on "Soil carbon sequestration: Needs and prospects under the 4 per 1000 initiative" held in Tsukuba, Japan. The member consists of experts from eight countries.

Long-term field experiments have been providing one of the most valuable scientific basis to assess long-term sustainability of agricultural lands. Now, ALTENA has an additional importance to examine the options and the degree of success towards the goals for "The 4 per 1000 Initiative: Soils for food security and climate" established during COP21 (Dec 2015, Paris).

Asia holds more than half of world population and experiences high pressure for agricultural intensification and expansion. Enormous variation in climate, soil type, and cultural practices is present in Asia. We need to account for these factors when assessing soil carbon sequestration potentials and agricultural sustainability. ALTENA is therefore established to promote ALTENA among Asian countries and beyond.

Mission

The mission of ALTENA is to provide scientific basis and management options for soil C sequestration and agricultural sustainability in Asia and beyond. Following is the present goals of our network to accomplish our mission.

  • To facilitate collaboration, exchange of information and scientists, and the formation of joint research
  • To provide long-term dataset to the global science community
  • To show the public and decision makers the importance of long-term field experiment thereby securing funding to maintain and strengthen such programs in Asia.
