|Speech Title: Innovative Irrigation Water without Pesticides for Organic Growers|
Abstract: The PRC calls for new innovations in farming practice while increasing the GDP per acre. The new irrigation water will increase the GDP per acre increase by 3 folds. The open door policy for the last 30 years brought in toxic pesticides and chemical fertilizers from the west and caused serious damages to human health and farmlands.
The new irrigation water consists of nano-bubble gases like activated oxygen, nitrogen and carbon dioxide. These are all natural fertilizers. The nano-bubbles penetrate into seed and plant tissues easily and cause at least 100% increase in crops, vegetables and fruits yields per acre.
The activated oxygen in the irrigation water also remediate residual toxic pesticides. It also kills insect larvae in soil which make the farm products into organic grade which increase the value by 300%.

|Speech Title: Dioxins Abatement of Incinerator Air Emission and Toxic Smog Air Management|
Abstract: The problem of incinerator compliance is the strict emission standards of toxic dioxins at less than 0.1 nano-gram per cubic meter of air emission. There are 2 effective emission abatement methods; soil or ground injection and nano-oxygen bubble air in spray mist countering the off gas emission respectively. Injection of dioxins containing off gas emission into shallow dry ground well (less than 30 meters deep) and relying on the effective porosity of the soil and clay minerals in the ground to adsorb the dioxins and other air pollutants. It is a very cost effective method. The polluted soil can then be remediated in-situ by combination electro-biochemical oxidation at less than $20 per ton of polluted soil. This is a no open air emission method. Also, electric arc carbon incinerators can be powered by clean 4 dimensional thermal solar energy system which are mobile and without fossil fuel burning. Another dioxins air emission control is to counter the off gas emission by spraying nano oxygen bubble containing water in spray mist form. The oxygen in nano oxygen bubbles has very high oxidation potential and stable (better than hydrogen peroxide and less than hydroxyl radicals). It is a very cost effective method to generate large scale nano oxygen bubbles water. The equipment that can generate large quantities of nano bubble water was invented in 2008 and remediated 6 kilometers long black stinking Kaohsiung River in less than 2 months. Subsequently, many polluted ponds and waterways were cleaned up by this type of water. The nano bubble water has numerous other uses in agriculture, cosmetics and medicine. The burning of fossil fuels create the toxic smog syndrome with highly unhealthy PM 2.5 particulates which can penetrate into our respiratory system and cause cancerous cell growth. The most effective measure is not burning fossil fuels. New thermal solar energy systems are more cost effect than fossil fuel power generation. A passive abatement method is to inject large volume of toxic smog into shallow dry wells just like mentioning above. The natural soil pore space and clayey minerals are excellent absorbents. The injected air can then be extracted as clean air and directed into highrise buildings or homes ventilation systems without the unhealthy PM 2.5 particulates. The air can then re-enter the atmosphere as clean air without harmful particulates. The same can apply to various industrial air pollution sources.

|Speech Title: Advances in Seasonal Streamflow Forecasting |
Abstract:Each month, the Australian Bureau of Meteorology issues operational seasonal streamflow forecasts of total water volumes for three months ahead for over 200 locations across Australia (http://www.bom.gov.au/water/ssf/). The forecasts are created using modelling approaches developed by the Commonwealth Scientific and Industrial Research Organisation (CSIRO) and other partners. Forecasts of seasonal streamflow can inform tactical management of water resources, allowing water users and managers to plan operational water management decisions and assess the risks of alternative water use and management strategies.
Forecasting streamflow over the next month, season and multiple seasons is a challenging task, because the predictability of climate over these forecast horizons is low. On the other hand, initial conditions of soil moisture, groundwater and other water stores in a catchment can have some relatively predictable effects on streamflow months ahead. State-of-the-art forecasting methods aim to (1) quantitatively capture, as much as possible, both sources of streamflow predictability and (2) statistically represent the remaining predictive uncertainty in a reliable manner.
In this presentation, I will give an overview of scientific approaches for seasonal streamflow forecasting, research progress made in Australia in improving the skill and statistical reliability of ensemble forecasts, and the HEPEX (https://hepex.irstea.fr/) international testbed initiative. I will also share Australian experience in using seasonal streamflow forecasts for water management.
