An integrated research and extension collaboration between 3 Pacific universities has helped to strengthen biosecurity and plant health for agriculture-dependent countries in the region. 

The ACIAR-supported program, which ended in March this year, has built on an earlier initiative – plant health clinics that worked directly with farmers. The newer project provided revamped university curriculums designed to equip agriculture graduates with biosecurity and plant health research and extension skills. 

Fiji National University (FNU), the University of Goroka (UOG) in Papua New Guinea and Solomon Islands National University (SINU) came together under an ACIAR-supported project to mount a coordinated defence against increasing pest and disease threats.

Multiple training pathways 

As one of the key project participants, Dr Lilly Sar from UOG pointed out that the threat to crops and food security from pest insects goes beyond borders.  

She said the initiative has embedded plant health knowledge and training at different education levels, which would ensure the benefits for crop productivity and to rural communities can be sustained. 

‘For example, UOG has developed 4 capacity-building pathways under this project – training for agriculture teachers, training in agriculture extension for undergraduate and postgraduate students, specific biosecurity and plant health training for extension officers, and also training and support for lead farmers,’ said Dr Sar. 

‘Lead farmers are influential and will have an important ongoing role that the universities will also continue to support.’

The project has been aided by biosecurity and curriculum-development specialists from Australian universities. 

Project leader Professor Michael Furlong from the University of Queensland said the aim was to equip the next generation of agriculture graduates with key plant protection skills. 

He said increased trade and movement of goods and people, plus potential climate change impacts, were increasing biosecurity risks for neighbouring countries, and for Australia. This was compounded by a lack of on-the-ground expertise in the Pacific region to identify, diagnose and resolve pest or disease incursions. 

‘We have also needed to address the disconnect between biosecurity research and local extension, and to raise awareness at government level that a crop pest or disease incursion needs to be given the same priority as natural disasters,’ said Professor Furlong. ‘The outcome for a farming community that loses its crops to a pest is little different to it losing its crops to a cyclone.’ 

Professor Furlong cited a current serious challenge in Samoa where the Asian citrus psyllid – one of the world’s most destructive citrus pests – has become widespread. It is not known how or when the incursion happened and there are fears it may already be undetected in other Pacific region countries. 

‘So our objective has been to develop a whole new framework for integrating research, education and biosecurity training which, through the universities, is also localised,’ said Professor Furlong.

Localised extension 

Different countries face different threats, such as coconut rhinoceros beetle, taro leaf blight, the giant African snail. Each country’s priorities, knowledge and experience has been represented in the application of the curriculum, training materials and the plant health clinics. 

Professor Furlong described plant health clinics as similar to medical clinics. A farmer brings in a plant showing insect or disease damage, a diagnosis is made and a prescription is written for treating the problem. 

These prescriptions also embody an increased emphasis on integrated pest management (IPM), which is a core component of a comprehensive manual that has been produced as part of the enhanced university curriculums. 

‘The manual, Plant health clinics: a trainingmanual for planthealth doctorsin Pacific island countries, covers the knowledge needed to be a plant doctor, to run a clinic, and to methodically diagnose and treat disorders, especially when presented with unfamiliar symptoms,’ said Professor Furlong. 

He added that this frontline capacity was further facilitated by the universities working together, sharing experiences and expertise to build a region-wide knowledge base and capability. 

High-priority pests of concern to Australia include giant African snail and Asian citrus psyllid. Trained extension staff in partner countriescan provide an early warning system, alerting national and international agricultural communities including those in Australia of these and other potential pests and diseases threats.

Tailored training materials 

The project developed curriculums and training materials under the guidance of the University of Tasmania’s Dr Caroline Smith, a specialist in curriculum development and adult learning, in conjunction with crop protection specialist Dr Grahame Jackson, who has more than 50 years experience working in the Asia-Pacific region. 

Dr Smith emphasised the importance of the curriculums and the training manual comprising input from all of the participating countries. ‘It allows training to be customised to a country or community, which is essential for encouraging farmers to use the clinics. And it is farmers who are the biosecurity frontline. If there is a pest or disease incursion it’s usually a farmer who sees it first.’ 

The educational material is complemented by an extensive suite of 500-plus fact sheets developed by Dr Jackson.  

‘There is very little knowledge of pests and diseases [in some communities], and IPM is a complicated concept, so we had to go back to square one,’ explained Dr Jackson. He said that as the plant health clinics become more widespread, they will also collect data that can be used to monitor pests and diseases and the effectiveness of responses.  

 

Targeted chemical use 

Dr Mereia Fong, Associate Dean Research and Innovation at Fiji National University, said another important role of the clinics was to improve farmer health and safety, and to reduce the amount of insecticide used. 

When farmers see crop damage, they tend to apply insecticide without knowing if the problem is a pest or disease. An accurate diagnosis at a clinic will reduce this and benefit farmers and the environment.’

Dr Fong said the integration of biosecurity and the plant health clinics into the university curriculum involved weekly classes, followed at the end of each semester by clinic experience. She said students gained practical experience helping farmers with symptoms and improved management practices. 

She also said the enhanced curriculum was popular with students who would use the additional knowledge and experience in a variety of ways: ‘Some will become extension officers, some will use biosecurity and plant health knowledge in other agriculture careers, while others will use what they have learned to help their families who are farming.’
