Australia’s Virtual Irrigation Academy (VIA) was announced as the winner of the Inclusion Award under the Water Changemakers Innovation Awards 2023 held at COP 28 this week.


The Water Changemaker Innovation Awards is a global initiative that recognises high-level commitment and leadership for climate-resilient water investments. The Awards also showcase the most promising climate-resilient innovations with the greatest potential for scale, replication, and further investment to support a water-secure world.


In its second great achievement, VIA was recently selected as a winner of the World Economic Forum's ‘Smarter Climate Farmers Challenge’.


This challenge called for solutions using climate-smart agriculture approaches to improve food production, promote better living standards, respond to climate change and lead to the efficient care of the planet’s resources within food ecosystems. Its focus areas include: knowledge, skills, and education; resource efficiency and sustainability; inclusive technology; and innovative financing.


VIA's world first Chameleon sensor helps small-scale farmers who are the most vulnerable to the effects of climate change to reduce water use while increasing crop yields and food production.


By enabling effective water management, VIA has the potential to transform the lives of millions of the world’s poorest people in the poorest countries that are already stricken by climate change.  VIA is already having a significant impact on farmers in drought-afflicted countries such as Malawi, Mozambique, South Africa, Tanzania and Zimbabwe.  Its application has limitless potential around the world as farming communities adapt to the impacts of climate change.


Revolutionising agriculture technology, farmers simply bury VIA’s soil water sensor in the ground.  Attached to a light, it shows blue when the plants have plenty of water, green when things are ok and red when they need a drink….taking guess work and outdated water usage practices out of the equation, maintaining soil nutrients and increasing yields.


Originally established by CSIRO and Australian Centre for International Agricultural Research (ACIAR), VIA is now a stand-alone not-for-profit, seeking and working with partners around the world to manufacture and distribute this transformative technology.

About us:

The Virtual Irrigation Academy (or VIA) - created by CSIRO in 2015 and funded by the Australian Centre for International Agricultural Research - develops technology specifically for the needs of low-income irrigation farmers.


Over the last 8 years, we have tested a big idea: what if we gave these farmers simple information about whether their crops were thirsty or not. We developed a soil water sensor - buried in the ground and attached to a light - that shows blue when the plants have plenty of water, green when things are ok and red when they need a drink.


We started in Tanzania and the results were extraordinary. Then on to Zimbabwe, Mozambique, Malawi, Ethiopia and into Asia - with much the same result. Farmers were hungry for this kind of information and quickly changed their irrigation practices.  A large majority of farmers substantially increased their yields.


But this was not the most surprising part. Almost all farmers who grew more food used less water to do so. Giving plants more water than they need leaches nutrients out of the soil, wastes energy for pumping and causes environmental problems such as waterlogging and salinity.


Soil water sensors like ours cost tens or even hundreds of dollars each.  Ours can be bought for less than $12 and forty thousand are already in use across 20 countries. Within a few years the sensor will cost half of that, and perhaps half again before the end of the decade.    


Farmers need information about water in their soil and that is what the VIA provides.  Perceived scarcity over water fuels conflict and conflict undermines attempts to equitably govern and share water in the contested world of managing common pool resources.


In 2022 the VIA became a not-for-profit company. The next step is to expand our production capacity and establish strategic knowledge and distribution partnerships in several locations around the world. This is because sensors are not a silver bullet in themselves, and this is not just a tech-fix problem. Growing more food with less water is a people problem.  We are challenging deep-seated traditions around the way things have always been done.


Building local knowledge and in-country capacity is key for farmers and stakeholders to understand how the sensors work, how to troubleshoot and carry our repairs and maintenance. And our quality assurance processes are fundamental in providing confidence around what makes for a low-cost but accurate sensor.

Soil sensors and data systems developed by the Virtual Irrigation Academy are applicable to 150 million of the poorest farming households in the world. It’s the first time in history these farmers have had access to this type of technology.


Irrigation is going to be a major part of adapting to climate change and most of this is going to have to be on small farms in low-income countries. Our technology is designed for these farmers and has been shown to work.  All we need now is the partners to scale.

Study reveals how climate patterns contribute to coral bleaching in the Great Barrier Reef

A new study finds a significant impact of the Madden-Julian Oscillation (MJO) and El Niño Southern Oscillation (ENSO) on coral bleaching events in the Great Barrier Reef (GBR). The GBR, covering almost 350,000 square kilometres along Australia's northeastern coast, is the world's largest coral ecosystem. Renowned for its biodiversity, cultural significance, and economic value, it contributes around $6.4 billion annually to the Australian economy. However, it faces serious threats from increasing ocean temperatures due to climate change. A new paper, Combined Role of the MJO and ENSO in Shaping Extreme Warming Patterns and Coral Bleaching Risk in the Great Barrier…

NSW Environment Protection Authority


The NSW Environment Protection Authority (EPA) has issued BlueScope Steel Pty Ltd a $15,000 fine after allegedly failing to comply with their Environment Protection Licence, which requires activities to be carried out competently. During refurbishment works, 13 cubic metres of industrial grout escaped from a shipping berth and entered Port Kembla Harbour. The incident occurred after containment controls failed, allowing the grout mixture to discharge into the harbour. NSW EPA Executive Director Operations, Jason Gordon emphasised the importance of all licensees carrying activities in a competent manner to prevent pollution incidents. “In February 2024, BlueScope were reinforcing a shipping berth…

Off balance: New studies unravel the climate pattern impacts on the Antarctic Ice Sheet

The Southern Annular Mode andEl Niño-Southern Oscillation are causing large year-to-year variations in Antarctic snow accumulation and surface melt. Findings from two new research papers are supporting efforts to predict how Antarctica will respond to future climate change. Change in the Antarctic creates ripple effects all over the planet, including sea level rise and shifts in weather patterns. New Monash research has untangled the influence of regional climate drivers, including the Southern Annular Mode (SAM) and the El Niño-Southern Oscillation (El Niño), on the Antarctic Ice Sheet. Snow accumulation and surface melting are two important processes that are key to…
