Counting coconut trees with drones in Western Samoa

On the Pacific islands of Samoa drone technology is used in a coconut tree survey to forecast more accurately yield and production of virgin coconut oil. 

In 2015 the Samoan agricultural non-governmental organisation Women in Business Development Incorporated (WIBDI) realised that it needed a new way to collect and organise comprehensive data from associated farms. The organisation helps local rural families actively engage through fair-trade in the niche market of organic products. They were wondering what would make it easier to carry out organic standards inspections and conduct counts of certain crops, in particular coconut trees.

Coconut is Samoa’s most important renewable resource and export product. The country exports copra coconut oil, virgin coconut oil, coconut cream, desiccated coconut, coconut fibre (coir) and shell products mainly to Australia and New Zealand. WIBDI is the largest exporter of virgin coconut oil in Samoa and its main buyer is The Body Shop, which is based in the United Kingdom.

In search for answers to the data collection problem, WIBDI turned to Samoan tech-services company Skyeye for help. Skyeye’s experts explained to them that the technology of unmanned aerial vehicles (UAVs) – also known as drones – was the perfect solution. It is cheaper than a manned aircraft and capable of collecting higher-resolution imagery than those that are available from a satellite.

Open source server

For its mapping work, Skyeye uses a fixed wing professional mapping UAV, which is capable of covering large areas in a single autonomous flight. ’The drone allows us to capture images of farms that are not easily accessible and it gives us the flexibility to fly whenever we want as long as the weather permits it. Being able to capture up-to-date imagery has been a massive benefit to this digitisation project,’ says Skyeye’s Geographic Information System (GIS) technician Ephraim Reynolds.

After technicians download images from the UAV, they process them into orthomosaics: stitched-together images that have been digitally corrected for distortion, so that they can be overlaid onto a map. They then open these image layers in a free, open source GIS computer programme, known as QGIS. In QGIS, they are able to digitise key farm features – and the high resolution drone imagery clearly shows individual coconut trees, allowing them to conduct a visual count of total tree numbers.

Skyeye uses a GIS feature known as a Web Feature Service (WFS), which allows them to grant users access to its geoserver – an open source server made for sharing geospatial data. With WFS, users are able to download individual layers of information, such as the layer containing information about farm’s coconut trees. With these geospatial data farmers then can make their own changes and updates to the digital map. ‘In this way, Skyeye is able to divide the labour and make the process of analysing the drone imagery faster and more centralised within one system,’ says Reynolds.

Locating landing areas for drones

To further speed up the process of mapping, Skyeye shows farmers images of their farms from the air so they can draw their boundaries. By estimating the age of the palm trees on each of the farmer’s property, WIBDI is able to forecast the yield and production of virgin coconut oil. These estimates can in turn be used to assess the feasibility of future business ventures, and to make more accurate estimates of expected annual profits.

While the drones have been a boon to WIBDI, they have not been entirely trouble-free. According to Reynolds, Skyeye’s biggest challenge has been locating suitable landing areas, as the drone requires an open area free of vegetation to safely land after completing a mission – and such an area can be hard to find on a tropical island. ‘Google’s satellite imagery in Samoa is outdated. Sometimes, we found that the best solution is to ask the locals in the village where we can find suitably clearing,’ he describes.

Maintaining a strong radio link to the drone was another hassle due to tall coconut trees, which can obstruct the signal and result in the drone not capturing images. ’For this, we shortened the range of the drone’s flight path, or found higher ground to launch it from,’ explains Reynolds.

By the end of January 2016, Skyeye had mapped 10,480 hectares by drone and counted 138,180 coconut trees. The drone survey of all 558 farms in WIBDI’s network should be completed by April 2016. In the future, Skyeye Samoa hopes to extend the tree-counting process it has developed for WIBDI.  ’As Samoa and the Pacific continue to realise how drone technology can be used in various industries, especially in agriculture, the region will become better able to reach large markets and keep up with modern advancements,’ says Reynolds.

Djiru Warrangburra Peoples share their traditional knowledge across generations: a P3DM experience in Australia

Attracting approximately 2 million tourists each year, the Wet Tropics region is home to more than 18 distinct Rainforest Aboriginal tribal groups for whom the region holds deep cultural and spiritual significance. Many of these Aboriginal groups deal with multiple threats to their traditional landscapes, due to pressures such as tourism, agriculture and population growth. As some of the most disadvantaged people in Australia, Aboriginal people often do not have the resources to address these threats comprehensively and regularly experience the loss of vital cultural heritage and access to their traditional landscapes as a result of these pressures.

The Djiru Warrangburra people are one of the culturally rich Rainforest Aboriginal tribal groups of the region. They live in and around the rainforests and coastal flats of the Mission Beach area, about 2 hours south of the regional centre of Cairns.

Djiru traditional lands are also home to some of the last remaining numbers of the southern cassowaryCasuarius casuarius johnsonii - a species endemic to the Wet Tropics World Heritage Area and listed as endangered. 

In April 2016 Djiru people began implementing a participatory 3-dimensional model (P3DM) covering close to 60,000 hectares (576 sq km) of land and sea, and including areas such as World Heritage, National Parks, freehold tenure.

At a scale of 1:10,000 the Djiru P3DM exercise is intended to encourage intragenerational sharing of knowledge vital to the longevity of Djiru culture ad the identity of Djiru people. Still in progress the P3DM is expected to be complete by June 2016. The project is being facilitated by the Wet Tropics Management Authority and is funded under the Queensland Gambling Community Benefit Fund.

"A contemporary guide to cultural mapping: An ASEAN-Australia perspective" now available!

The cultural mapping process may focus on the past, the present and also the future. Cultural mapping can be used to monitor change in material culture as well as intangible cultural heritage. A cultural map may be created as an end in itself or provide an input into other endeavours.

Many methods and technologies are used to create cultural maps; some are simple and ephemeral such as drawing in the sand. Others use the latest technologies to locate cultural phenomenon spatially using geographic information systems. Whatever methods are used to map culture or cultural products, the map most often takes a physical form (a list, matrix, chart, diagram, design, website, sound recording, video, drawing, painting, textile, sculpture or model) where information is gathered, arranged and presented physically or virtually. In this context the authors use the term map as a mental model and mapping as mental model making as they explore the body of knowledge associated with this expanding field.

The Guide is available free of charge due to the generous support of The Australian National University, the Australian Department of Foreign Affairs and Trade, The National Museum of Australia and The ASEAN Secretariat, Jakarta. It is hoped the Guide will be available online in July/August 2013.

Artlab Australia is co-managing the distribution of hard copies of the Guide. There is a limited print run so if you want a copy we recommend that you place an order immediately. A payment is required to cover the costs of packaging and postage. Postal charges vary enormously depending on destination. To order, please email: artlab@dps.sa.gov.au

Sculpture and Science help in Planning to Preserve The Mutton Hole Wetlands in Australia

A 3D model of the Mutton Hole Wetlands near Normanton has been developed as a starting point for community consultation and discussion about how best to preserve and use the Mutton Hole Wetlands.

The Mutton Hole Wetlands are situated just to the North and West of Normanton, and are a part of the Southern Gulf Aggregation, the largest continuous wetland of its type in northern Australia. Being vital for bird migration routes across northern Australia, the Southern Gulf Aggregation is considered to be of state, national and international significance.

In the past the wetlands formed part of the neighbouring Mutton Hole cattle station, but the area was declared a Conservation Park in 2004. Currently managed by Queensland Parks and Wildlife, Carpentaria Shire Council has been considering managing the park themselves. As a part of this consideration the Northern Gulf Resource Management Group has gained funding to write a management plan for the wetland.

The management plan will highlight Aboriginal culture as well as the environmental values of the wetland in a plan to conserve it for future generations. There is strong support from the scientific and local community for use of the wetlands for bird watching, teaching and eco-tourism. As a step towards greater community consultation a model of the wetland area was built and is now located in the Normanton Visitor Information Centre (Burns Philp Building).

Over six weeks in April and May 2009 students and staff from Normanton State School and the Gulf Christian College worked together with Dr Isla Grundy of CSIRO to construct a 3D model of the Mutton Hole Wetlands, using a technique called Participatory 3D Modelling (P3DM).

The model was made by first tracing the image of the wetlands from a 1:9500 satellite image onto a large piece of cardboard, then other features were added on or cut out. Finally, the rest of the landscape was painted onto the cardboard and the boundary of the Conservation Park marked with thread.

P3DM is a relatively new technique developed in the Philippines to support collaborative resource use and management, aimed to facilitate community participation in problem analysis and decision-making. This is the first time this participatory technique has been used to make a landscape model from cardboard in Australia.

Since mid-May 2009 the model has been displayed at the Normanton Visitors Information Centre and on Thursday 21st May there was a formal public opening when students, parents and interested community members came to see what the schools had been working on. The exhibition was opened by Vicki Jones of Northern Gulf, along with Isla Grundy of CSIRO and Agnes Hughes from Normanton State School. The forty or so people who attended were able to take a closer look at the model and discuss wetland history and potential use. The community at large was invited to give it’s opinions and ideas on how the Mutton Hole Wetlands should be managed and used in the future through individual community consultations and group discussions held at the Information Centre.

Written In the Land, the Life of Queenie McKenzie

This very visual book tells the story of the life of an indigenous ‘law woman’ from the East Kimberley area of Western Australia, Queenie McKenzie. Queenie was recognised as an Australian Living Treasure before she passed away in late 1998 for her cultural leadership and contribution to the arts. What is different with this book is that the story of Queenie’s life is placed within the landscape that she knew as her traditional land. The cover image, is a topographic map of the women’s sacred dreaming site that no longer exists, it is now a diamond mine. Each of the five chapters is spatially located within the landscape of Texas Downs, Queenie and her peoples traditional lands that were ‘settled’ in the late 1880’s by white settlers who claimed the land.
The story is told often in Queenie’s own words and shows the many ways that indigenous people are connected to the land, it discusses issues such as mining of sacred sites, dreaming sites, skin groups - the Australian indigenous governance system, rainbow snake, massacres and parts of the history of growing up as an indigenous child during the impacts of white settlement. As Queenie was an acclaimed artist it also contains many images of her artwork, her maps of her country and sacred sites.When Queenie passed away these traditional ‘law’ practices ceased. Many years before Queenie had revived these annual practices after they were stopped during the settlement time, it was in the 1980’s that she insisted that they begin again. It has been 10 years since her death and the work on the book began between the author and the female elders, to keep Queenie’s legacy strong. Funds from the book are returned to the community for that purpose. It is a tragic reality that Queenie’s generation are the last remaining elders of the area who hold the land based knowledge of sacred sites, these people will all be gone within 2 years yet this is not seen as an urgent need in Australia by the Government, to provide resources and training to indigenous people to map these sacred locations and the associated knowledge.
