CIRAD Coconut GIS training in Vietnam: summary and planning

Dr Roland Bourdeix (CIRAD) was invited by the Department of Perennial Crop from the Research Institute for Oil and Oil Plants (IOOP) to organize a training on Geographical Information Systems (GIS) applied to coconut research and development.

Fourteen IOOP researchers and technical staff participated the training. The programme was intended to provide a global overview of the use of GIS in coconut research, and more specifically on the following points: 1) Multi functional landscape management and new trends in coconut conservation and breeding 2) collecting germplasm and integrate geographical and other data using the CGRD (Coconut Genetic Resources Database) and Kobotool box which allows to collect data from cell phones; 3) Managing ex situ genebank accessions and field’s experiment using CDM (coconut data management) and Microsoft Foxpro; 4) the Qgis and Diva-GIS software for managing geographical information. 5) Maxent to predict favorable cultivation zones and 6) Google Earth and other online tools for making interactive geographical representations. All the cited software except Bandicam and Foxpro are free or kindly provided by CIRAD; most of them are open source. Researchers were also trained to video making using Bandicam and Microsoft Movie Maker. Field visits were conducted in research centres and farmer's fields to test the gathering of data with android cell phones, and to prepare a project on assessing a traditional technique from Mekong farmers for reducing the vertical growth of coconut palms. About 10 GB of HD video shootings has been taken and a copy was let to IOOP. A short movie was co-produced during the training. Most of collected information was released online at the URL: http://coconutvietnam.blogspot.fr. Many of the new concept and ideas presented during this training comes from a recent book chapter (1) of an Indian CPCRI book and from the compilation of the Global Strategy for Conservation and Use of Coconut Genetic Resources, all in press. The training was prepared with the help of Dr Geo Coppens and Gaëlle Viennois, CIRAD researchers, and following a dedicated training provided by the CMAEE Join Research Unit in Montpellier, France.

    "Coconut bonzai": reducing the vertical growth of Tall-type coconut palms

    A traditional practice from farmers of the Mekong Delta

    This video can be see in HD or any lower resolution, please choose the best option according to the quality of your connection. Also available on the website of Diversiflora International

    In 1998, in the framework of an expertise on collecting strategies (Bourdeix et al, 1999[i]), the island of Hung Phong (01008N 10622E) in Mekong Delta was visited. While interacting with farmers, it appeared that what farmers called “Dwarf’ and “Tall” coconut palms did not fit with what was described in all other countries. More precisely, some coconut palms described by farmers as “Tall-types” had the typical stem of what is normally called “Dwarf”: a thin stem without any basal bulb, and very short internodes.
    We finally find an explanation (see fig. 1 and 2). In this island, farmers had a very special traditional practice, never described before (as far as we know).  

    Figure 1. View of different coconut stems. From left to right: Malayan Dwarf, Compact Dwarf, Indo-Atlantic Tall, Asian-Pacific Tall types of coconut varieties (Photos R. Bourdeix, Côte d’Ivoire).
    When 2 years old, the young tall coconut palm is removed from the ground, its roots and leaves are cut and, after that, the palm is planted again in the ground. Such palm will develop stem similar to those of Dwarf cultivars: no bole, very short internode distance and slow vertical growth. Farmers said that this practice causes a delay of about one year on the starting of production but does not affect the future performance of the palms.

    Figure 2. View of different coconut stems in Mekong Delta. Normal stem of a Tall-type coconut palm (left) in comparison with same variety treated for reducing growth (Photo R. Bourdeix, Vietnam).

    It could be very useful to to scientifically assess this traditional practice, for both extending the lifespan of accessions in ex situ Coconut field genebanks, and for proposing a new ways of cultivation making harvest and field management more convenient and safe.

    Entrance of Dong Go Research Centre
    The centre was visited on 22 and 23th January 2016. It hosts the National Coconut Genebank of Vietnam.

    Each tall-type coconut accessions is composed of palms of different ages; the palms are progressively replaced when the first palms dye. The technique to replace the missing palms is based on open pollination within a block composed of different populations of the same variety (for instance Ta Tall). Inter cropping is conducted with various other crops, such as Jack fruit, Papaya, etc... Palms are numbered by a number of row, and a number of palm in the row painted on the stem.

    We made an almost complete tour at the borders of the gene bank. At North the centre is delimited by a road and a fence with some open entrance; at South is is delimited by a canal with no fence. At the east side, it is delimited by a small road with no fence, so people may easily come in  the gene bank and take coconuts. At the west side it is delimited by house, some of them used by the employees of the gene bank. Land tenure could become a problem. In the  past, about a sixth of the available land of the centre (on the West side) was already taken back by the local government  to conduct other activities.

    The centre presently serves as a gene bank only for coconut palm. It is advised to strengthen the involvement of the centre in conserving other tree crops. This option has several advantages, including to:
    •           Increase the global commitment to promote the importance of the gene bank. If more than one crop is conserved, gene bank will become increasingly mandatory and committed places for conservation of genetic resources. 
    •           Increase the visiting frequency to the gene bank. Researchers working in genetic resources of different crops will meet more frequently, exchange more information, and cooperate more closely.
    •           Make at least part of the gene bank closer to the planting systems used locally by farmers, as many of them practice inter cropping.
    •           Ensure a better agronomic management, especially for inter cropped fields that often require irrigation facilities and higher fertilization and will serve as demonstration fields.
    •           Benefit from the multi functional use of the landscape. Some coconut plantations, especially seed gardens, are generally surrounded by other tree crops for pollen isolation purposes. Instead of planting any tree crops, these buffers areas can also conserve genetic resources of appropriate species.

    A good opportunity could be to extend conservation activities in Dong Go to many other palm species. A large plot and part of the swampy areas could be planted with at least 20 other palms species. When adult, part of these palms could be sold to city and tourism landscaping units who generally buy such palm at a very good price (about 100 USD per meter of stem), and regularly replaced.
    Conversely, coconut conservation could also be integrated into many other agricultural research centres’ programmes within the tropics. Thousands of coconut palms are planted in these research centres without considering genetic resources and diversity aspects. Thus, developing multi functional land use is one of the highest priorities, and hence has thus recently been included as a new theme of the CGIAR research programme Forests Trees and Agroforests (FTA).
    For instance, in Côte d'Ivoire, West Africa, the CNRA is starting to implement this last approach by duplicating accessions of the International Coconut collection in Côte d’Ivoire. Simulated “coconut islands” will be planted in five of the 13 CNRA research centres scattered around the country. Coconut germplasm will be planted in isolated small units of about one hectare, each conserving only one Tall-type accession and each planted in reproductive isolation in the middle of other tree-crop plantations.

    Controlled Pollination Technique

    During the past 5 years, the technique of controlled pollination with bagging was not applied in Dong Go Research Centre. Some material remains, such as aluminium isolation box and green bags (French type). All experimentation were conducted using the techniques of open (natural) pollination and assisted pollination (emasculation of dwarf inflorescence in the seed garden and pulverization of pollen coming from another palm). The seed gardens, both in Dong go and Trang Bang, are not isolated by a sufficient buffer zone preventing pollen from outside to reach emasculated inflorescences. So it is advised to use the controlled pollination technique with bagging for research and rejuvenation purposes and to isolate the seed garden with large tree crops for improving the quality of the hybrid seed nuts.
