I identify myself as a 'generalist' in that I work across a range of disciplines within agriculture, horticulture and natural resource management. However my focus is primarily agroforestry and then agricultural extension, particularly in the context of developing countries. My work uses both biophysical and social science methods. I have also published in the areas of forest management, tree water use, horticultural plant pathology, agricultural extension, bioenergy, tree genetics and climate change.

As I retired from teaching activities at the end of 2021 I can no longer accept research students. However, I remain in an Adjunct role to undertake research.

Here is a brief pictorial description of our research in Nepal and Papua New Guinea undertaken for the Australian Centre for International Agricultural Research (ACIAR)

The focus of our current research in Nepal is to improve food security and livelihoods through agroforestry and community forest. In Mid-hills of Nepal farmers' livelihoods depend on tree resources both on private farm land (agroforestry) and community forests. 

Here is our EnLiFT project website

 Here is a story "Growing Hope: Australian overseas aid empowering farmers in Nepal" on ABC TVs program Landline. Our project was visited along with two other ACIAR projects in Nepal.  

Here is a related article on  EnLiFT: How Australia is helping Nepalese people rebuild after devastating 2015 earthquake

We are also concerned with finding practical and profitable alternatives for land that is being under-utilised.  Land is being abandonned because of labour shortages arising from young rural males opting for employment in India or the Gulf countries

Livestock are an important component of the mid-hills farming system, both for subsistence consumption and income generation. The major source of livestock nutrition comes from tree fodder from agroforestry trees or community forests.  Note the tree in the distance, how it has been heavily lopped for the fodder.

The major source of crop nutrition in the mid-hills is farm yard manure from the cattle, buffalo and goats fed on the tree fodders.  So the agroforest and community forest trees are indirectly a major contributor to human nutrition and household income.

 In the community forests we are engaged with demonstation trials of different silvicultural options to better match forest management to community needs. Some options are, for example, to open up plantations and plant fodder trees and high-value crops such as cardamon

Our work also involves training in business skills so that farmers and community forest user groups can make the most out of the new commercial opportunities opening up to them.

 

 

 

 

PAPUA NEW GUINEA

The work in Papua New Guinea similarly aimed at improving rural livelihoods by better understanding the fuelwood market, finding the best trees to grow for fuelwood, and facilitating charcoal producer-vendor groups.

FUELWOOD SURVEY

We undertook a comprehensive survey of domestic and commerical fuelwood use and sales in Port Moresby, Mt Hagen and Lae, and the Western Highlands, Eastern Highlands, Morobe and Chimbu provinces.  We interview 3,964 domestic users, 157 fuelwood sellers, 66 commercial / industrial users, and monitored the daily use of 36 households.

We learnt a lot about the fuelwood economy in PNG that will inform public energy policy.  You can read about it here

fuelwood trial
Harvesting short-rotation coppicing fuelwood at Pugamp, near Mt Hagen, Western Highlands Province

Ten fuelwood species were evaluated in short-rotation coppicing (SRC) systems in replicated field sites around Mt Hagen and Port Moresby. They were grown at 2 spacings and evaluated against locally used, but non-coppicing species (e.g. Casuarina oligodon in highlands). Some candidates were also grown in farmer-managed woodlots and alley-farming systems. The evaluation included: growth measurements after 2 years; coppice vigor; burning characteristics as firewood and as charcoal; and consumer and market acceptance.   You can read about it here.

The initial market acceptance of this 2-year old firewood was not strong because it looks so different from what people normally buy.  Fortunately some of the better growing species were well accepted as firewood after people stated trying it.  Nevertheless, we realised farmers would be better off value-adding this wood by converting it into charcoal. So we facilitated the establishment of charcoal producer-vendor groups.  This involved first understanding what group business structures would work best for rural people in PNG. It turnd out that a very different business structure emerged in the coastal city of Lae, than in the highlands city of Mt Hagen.  This reflects the very different cultural settings in the two regions.
