Towards understanding long-term impacts of indigenous agriculture on soils: Hawai`i as a model system


Towards understanding long-term impacts of indigenous agriculture on soils: Hawai`i as a model system
April 22, 2021
Location
Zoom
Growing recognition of the tremendous impacts of our modern agricultural system has spurred an interest in understanding the impacts of agriculture on soils and soil health. Indigenous agriculture, which in many cases has been practiced for centuries or millennia on the same land, provides opportunities to understand the long-term impacts and sustainability (or not) of these systems. Hawai`i in particular is an unparalleled system in which to examine these impacts due to the tremendous and highly organized diversity of substrate age, climate, and the resulting ecologies. This talk covers and overview of the intensive Hawaiian rainfed systems and the previous and ongoing work exploring the interactions between soils, agriculture and society over time. ....

High-tech detection determines pineapple harvest needs | University of Hawaiʻi System News


In a new study funded by the
U.S. Department of Agriculture’s Small Business Innovation Research program, researchers in the University of Hawaiʻi at Mānoa’s College of Tropical Agriculture and Human Resources, IntelinAir, Inc. and Columbia University are investigating whether remote sensing and computer vision can help pineapple growers carry out regular inspection of the field and automated counting of flower intensity.
The natural flowering of pineapple was the basis of the industry up until the 1960s. Now, pineapple fields are forced in blocks to flower, with a chemical that releases ethylene and induces flowering, making the fruit available year-round. Since pineapple is hand-harvested, a grower’s ability to harvest all of the fruit of a field in a single pass is critical to reduce field losses, costs, and waste, and to maximize efficiency. ....
