Researchers in our documentation centre assign keywords to each article published in Down To Earth. This is done according to the main themes and subject of the article. Using this option in search will help to increase the relevance of the articles found.

Our keywords have been placed under three hierarchical levels, and this feature allows you to select keywords relevant to your search from all the three levels.

To begin with only the first level keywords have been displayed and the subsequent levels will be displayed on selection of keywords.
