University of Maryland at Eastern Shore: Food Preservation Program

The food preservation program was held at the Dominica Grammar School in May 2016 by food scientists from the University of Maryland at Eastern Shore; Dr. Patel and Dr. Nando.

The Dominica Grammar School (DGS) is a public co-education secondary school in Roseau, Dominica, which was established in 1893. It is one of the oldest educational institutions on the island and no longer functions as a traditional grammar school. It has expanded its curriculum beyond its historical scope.

The scientists taught Dominican farmers and entrepreneurs food preservation technology focusing on mango preserves.

Dr. Patel, featured in the above video, can be seen teaching the food processing class in The Commonwealth of Dominica to the attendees at the Dominica Grammar School.

Their program was part of the memorandum of understanding with the University of Maryland at Eastern Shore and Dominica facilitated by Rebuild Dominica, Inc. in collaboration with the Dominica State College, the Caribbean Agricultural Network and the local Global Environment Fund.

Above is an interview feature of one of the attendees during the program, Dylan Williams.

Rebuild Dominica Partners With The Global Breadfruit Institute

As the journey to reconstruction continues, Rebuild Dominica forms a new partnership with the Global Breadfruit Institute to boost recovery efforts. This partnership follows the donation of advanced breadfruit cultivars from Dr. Julius Garvey, the son of the late great Marcus Mosiah Garvey, who also committed to agricultural reconstruction efforts.

The Global Breadfruit Institute advised they were aware of Rebuild Dominica’s international campaign to support The Commonwealth of Dominica following the damage caused by Tropical Storm Erika. To support this campaign, Global Breadfruit was inspired to provide a generous gift of 1,500 breadfruit trees.

The above video provides a glimpse of the breadfruit plants at the Dominica Ministry of Agriculture greenhouse. The video is narrated by Errol Emmanuel, Rebuild Dominica (RD)  member on island and Director of the Caribbean Agricultural Network: a collaborating organization to Rebuild Dominica.

In a statement of support to Rebuild Dominica’s efforts to revive agriculture on-island post Erika, Blair Lampert of Global Breadfruit stated, “This collaboration with Rebuild Dominica is part of a long-term effort, which unites local public and private entities engaged in business, research, agriculture, and welfare that will rely on Rebuild Dominica to proliferate optimal breadfruit varieties island-wide.” A sentiment shared by supporters of Dominica’s recovery.

A previous donation of breadfruit trees by the admirable Dr. Julius Garvey arrived in Dominica in the weeks preceding Tropical Storm Erika. This additional gift from the Global Breadfruit Institute is beneficial in furthering the mission of Rebuild Dominica. To learn more about the initial donation, the following excerpt from the Caribbean Agricultural Network’s (CAN) August 2015 press release is provided below:

According to the CEO of the Caribbean Agricultural Network (CAN) Major Francis Richards, the cultivars (Ulu-fiti) and (Otea) are the donation of New York based General Surgeon Dr Julius Garvey, the last son of Marcus Garvey.

At the end of the hardening process, the objective of the project is to distribute the plants within the seven (7) agricultural regions on island. Upon arrival the cultivars will be transported to the Ministry of Agriculture’s greenhouse facility at Portsmouth where they will be hardened for three months prior to distribution to local farmers. The advanced cultivar types sent to Dominica are fast bearing and will fruit within 2 to 3 years, compared to the standard 3 to 5 years.

Dr. Garvey is a member of the Caribbean Agricultural Network and has dedicated himself to the development of Caribbean food security, in accordance with the principles of self reliance advocated by his father who founded the Universal Negro Improvement Association in the early 1900s. Dominica was a major base of support for the UNIA during its early years and Marcus Garvey himself was invited to Dominica in 1929 with the aid of UNIA representative, noted local poet and self rule activist JR Ralph Casimir.

A Case for Improved Soil and Land Use Management in Dominica

Dominica’s national motto “Après Bondie C’est La Ter” meaning “after God is the land” highlights the importance of the land (the soil) to Island. The amount of precious top soil eroded by the torrential rains during the Erika disaster may never be quantified or featured among all we have lost. Nonetheless, losses incurred due to landslides and soil erosion and the subsequent impact on communities and livelihoods highlight the need to elevate the importance of soil and land use management in Dominica.


The 68th United Nations General Assembly declared 2015 as the International Year of Soil. A primary objective was to raise awareness among civil society and decision makers of the profound importance of soils for human life. As a non-renewable resource, its preservation is paramount for food security and our sustainable future.
Soils are not merely parcels of uniform materials. Instead, they are units with characteristics that change vertically downwards through different layers and horizontally in every direction. Therefore, to describe a soil it is not sufficient to only look at the surface, a vertical cut or boring must be made and the different layers from the surface to the parent material (underlying rock) carefully examined.

The soils of Dominica were classified by Mr. David Lang over 40 years ago. His work provides general descriptions of the major soil types, soil forming processes and includes several important recommendations for land use planning and agricultural development. Mostly, the soils are formed by the weathering of volcanic rock. The weathering process results in the formation of clays and secondary minerals. However, the unique properties of the respective soil types are based on the underlying rock and as influenced by environmental factors, rainfall patterns, topography, vegetation and the extent of weathering.


The physical and chemical characteristics of our soils, suitability for agriculture and other land uses are largely dependent on the type and quantity of clay they contain. For example, soils along the west coast between Jimmit and Tarreau dominated by Smectite clay minerals are noted for their shrinking and swelling properties. They shrink and crack considerably when dry and expand when wet. This activity is responsible for the cracks and movement frequently observed in the paved roads in that area. The Smectoid clays differ from soils on the north east, around Marigot, which are dominated by Kandite clay minerals. Kandoid clays are generally highly weathered (older), appear reddish to red-brown, are well-drained and better suited for agricultural development.

Several studies have investigated the mechanics of landslides in Dominica. The steep slopes, high rainfall and high water holding capacity of our soils are some of the factors that predispose many parts of the island to landslides. While heavy rainfalls are common in Dominica, it is the prolonged precipitation at high intensities, as occurred with Erika, which is capable of causing serious destruction from landslides.


Efforts to rebuild Dominica must be focused on building resilience and adapting to climate change impacts. Soil conservation and land use planning based on available technologies and the findings and recommendations generated from scientific studies (most of which already exist) should guide policy decisions and inform activities at the farm and community levels. We must also rely on the practical experience of individuals who have continued in the traditions of our forefathers, by stabilizing slopes with deep rooting crop and forest trees, bamboo and vetiver strips and who willingly adopt the approach that some extra work now can set the foundation for a sustainable future.

Rebuild Dominica and the Effort to Combat Black Sigatoka

Black Sigatoka Disease (BSD) is a fungal infection of the banana leaf which has plagued Dominica’s banana and plantain crops. In the wake of the Erika disaster, it is even more important to support the rebuilding of Dominica’s agriculture sector by such projects inspired and directed by collaboration between Dominicans, and friends of Dominica, at home and abroad.

BSD first identified in Dominica in 2012 is caused by the fungus Mycosphaerella fijiensis similar to Mycosphaerella musicola the cause of Yellow Sigatoka which we have usually called banana leaf spot. BSD affects both highly susceptible Cavendish banana cultivars such as Robusta and Giant Cavendish as well as plantains to a lesser extent. M. fijiensis is more aggressive than M. musicola and replaces it in countries it has invaded.

Infection begins on the young leaves as they emerge at the top of the plant and results in major necroses of leaves, destruction of photosynthetic leaf tissue, early immature ripening, and yield loss.

In our highly humid tropical environment there are two strategies for BSD control, fungicide control and selection of suitable resistant cultivars. Fungicide control is very expensive for cost of fungicides, labour cost as well as frequency of spray cycles. The two strategies can run currently..short term use of fungicides, good agronomic practices (soil testing, fertilizers, drainage, field sanitation, proper calibration of ground mistblowers etc) and longer term field testing and provision of resistant cultivars to farmers. For fungicide control optimal sprays should depend on single fungicides or mixtures of mostly systemic fungicides with different modes of action in banana spray oil or oil emulsions, a workable biological forecast system to reduce number of sprays and laboratory testing to detect early any development of fungicide resistance. Forecasting has been known to reduce sprays from over 40 per year to less than 10. We will need trained field personnel to do forecasts on weekly basis.

So for existing Cavendish and plantain farms and any new plantings. e.g with recently imported tissue culture Cavendish cultivars from VITROPIC in France, fungicide sprays will be necessary. Longer term solution will depend on partially resistant cultivars and/or genetically modified bananas. Dr Clayton Shillingford with collaboration of Errol Emanuel and Dr Davison Lloyd are field testing nine banana and two resistant plantain cultivars obtained from BIOVERSITY INTERNATIONAL, Belgium, the world’s largest Musa collection, to determine suitability for cooking, ripening for domestic and export markets and agroprocessing. The resistant cultivars seen here were weaned and hardened in DAPEX shade house, Fond Cole and are now planted in the field for evaluation..(rate of leaf emergence and total leaves, ratooning rate, measure of BSD compared to Cavendish cultivars, plant height at shooting, bunch weight and configuration, hand and finger size and shape etc). to be followed by cooking and ripening and organoleptic tests for taste, sweetness, texture etc. Water shortage is an important limiting factor in agriculture and the problem is likely to get worse as a result of climate change. Irrigation is routinely used but we will also field test the cultivars by phenotyping for drought.

Rebuild Dominica is supportive of the efforts to combat black sigatoka. We intend to promote the best practices in agriculture and industry. We have made a start. Donate here and help us finish the job!
