The role of agriculture in the country's economy Major food crops, cash crops and trends in production
Livestock production has been holding its own, with poultry production satisfying 10% of domestic demand and near self-sufficiency in pork being achieved. Quantities of fish landed have been falling, but Grenada remains a leading Caribbean exporter, with exports increasing by 14% in 1997 (See Table 1.2.8).
Grenada imports most of its livestock products requirements, mainly from the USA. For example in 1997, 94% of the poultry meat consumed locally, was imported. It is however self-sufficient in egg production, but imports about 94% of the poultry meat consumed locally. The livestock population, with the exception of sheep and goats has declined significantly during the period 1961 to 1995 (See Photo 1.2.1).
Food security and Food Production Declining exports led to an increase in the food supply, but in this case, the increase consists primarily of bananas. While the banana is a staple in the Caribbean, and its uses are many, export earnings are needed to import the protein sources that the country needs. Foods produced domestically included a group of 24 items among which are arroids, green and yellow vegetables, beans an peas, corn, citrus and annonas. Domestic food production, during the period 1987 to 1996, has fluctuated between 12000 and 15000 metric tonnes per annum. The greater proportion of that production is consumed locally. Fish production, for the same 1987 to 1996, fluctuated between a low of 1,289 MT and a high of 2,214 MT. Local fresh fish consumption is also on the decline. Between 1992 and 1996, local fresh fish availability measured on a per capita basis, fell from 18 kilogrammes to 8.3 kilogrammes. Historically, domestic livestock production has contributed significantly to the domestic food basket. However, this significance has declined over the years. Between 1961 and 1995, not only has the number of farms having livestock as part of their operations declined but also the populations of cattle, pigs and chickens have not grown in significant numbers. The five-year average of imported fresh meats and meat products for the period 1987 to 1990 was 10,234 MT. Trade Liberalization Much of the increased demand for fruits and vegetables
originates from the expanding tourism sector. In 1995, Interviews with
farmers in Grenada revealed that they had experienced difficulty competing
with imported fruits and vegetables in the local tourist market. Grenadas
traditional exports have been in decline on account of problems of poor
quality, disease, and rising costs. Non-traditional exports have not
responded quickly to the changing economic environment. Trade liberalization
is yet to make its full impact on the economy. 1.2 > 1. 1.3 Climate
Climate description Grenada has several mountain masses, one rising to 2749ft. (840 m) at Mount St. Catherine, which cause a marked upward deflection of the westerly morning moisture-laden air. The rising sea air is cooled by expansion, and the moisture is condensed so that orogenic cloud formations and often heavy precipitation result. Climate data The extremes of Grenadas wet and dry season rainfall regime and its temporal and spatial pattern create wide variations in annual precipitation at different locations. Grenadas rainfall is highest in the hilly or mountainous part of the country. For example Grand Etang, located at an altitude of 600 m, normally receives about 3880 mm of rain a year. Rainfall intensities are frequently greater than 50 mm/hr, and maximum intensities of 112-132 mm/hr have reported (Eschweiler, 1982a). By contrast, most of the valleys and coastal plains are relatively dry, with annual precipitation averaging about 990 mm at Point Saline.

2.1 Geomorphology and physiographyThe interior of Grenada is dominated by mountain peaks, steep ridges, and deep narrow valleys. The volcanic geology of the interior, is the dominant factor that produced this landscape. A single north-south trending ridge is also the major watershed of the island. Grenadas principal peak, Mt. St. Catherine is 833 m high and is located in the northern half of the island. Carriacou rises to a height of only 297 m at High North, while Petit Martinique attains an altitude of 226 m. The coastal periphery of Grenada presents a landscape which is much more subdued than the interior. The western side of the island displays a more rugged aspect as the central ridge is nearer to the coast on that side; the slopes are gentler on the east, and there are some fairly extensive coastal plains. The topography of the southwestern and northeastern parts of the island consists of low hills. With the exception of the harbour at St. Georges and Halifax, the west coast consists of a series of shallow bays separated by headlands, as do the north and northeast coasts. The southeast coast south of Telescope Point and the south coast westerly to Pt. Salines are deeply indented with many small bays backed by mangrove swamps. 2.1 > 2. 2.2 SoilsAccording to Ternan, et al (1989) the soils of Grenada are dominated by clay loams (84.5%), followed by clays (11.6%) and sandy loams (2.9%). The 3 major types of clay loam are Woburn, Capitol and Belmont. In Grenada, the dominant soil-forming factors are climate and topography. Climate is the most important single factor, specifically differences in total annual rainfall and in the length of the dry season. In some areas, the rocks are geologically young, and soils formed from rocks have not had time to mature. Grenadas soils are mostly well-drained and reasonably fertile. Together with high temperature and rainfall in most areas, the countrys land base has considerable potential for productive crop growth. However, as a mountainous country there is also a high erosion potential, a factor which places substantial constraints on the way the vast majority of the countrys land base can be sustainably utilised (See Photo 2.2.1).
2.2 > 2. 2.3 Land UseThe agricultural system in Grenada is one of mixed cultivation particularly on small farms. At present, some 90% of the small farms are under 5 ha (12.3 ac) in size (Ternan, et al., 1989) (See Map 2.3.1).
Land use areal trend The figures presented in Table 2.3.1 are based on the Agricultural Censuses of 1961 and 1975 and on air photo interpretation conducted in 1982 by Eschweiler (1982b). The most substantial land use change occurred in the 1970s with an average annual decline of 500 ha in total area under agriculture between 1967 and 1975 (Ternan, et al., 1989). Among the agricultural land uses in Grenada, 10 units
or classifications based on cropping patterns have been identified Eschweiler
(1982b). The following is a brief description of each of these land
use units.
Agricultural land use units
Annandale watershed occupies 202 ha and Concord Watershed 96 ha. Total area for Grand Etang region is 2,046 ha (6.6% of Grenada). The proposed Mt. St. Catherine Park occupies 573 ha, all government owned. The Mt. Hope-Clabony watershed adjacent to Mt. St. Catherine occupies 262 ha. This region encompasses 835 ha (2.7% of Grenada). The proposed Levera Park occupies 220 ha, 48 government owned and 172 privately owned, or 0.7% of Grenada. The proposed three parks, therefore occupy 2.541 ha (8.1% of Grenada). However only 2,147 ha (6.9%) are government owned. Perhaps only 7,000 ha or about 3% of Grenada are comprised of undisturbed climax forests.
2.3 > 2. The most recent land capability study for Grenada was conducted by the Ministry of Agriculture (Eschweiler, 1982a). The methodology used was based on a land unit approach in which a series of units were defined (primarily according to land form, slope and soil characteristics) and subsequently mapped. An earlier land capability study (Vernon et al., 1959) identified seven broad capability classes based on overall suitability, taking into consideration, among other factors, the risk of soil erosion or other damage and the difficulties of management (See Table 2.4.1). Within each class, four (4) possible limiting factors were identified, creating a number of subdivisions within all classes except Class 1 which has no limitations. These limiting factors are: slope and erosion risk; seasonal or permanent excess water (poor natural drainage); edaphic factors (eg. Shallow or droughty soil); and climatic factors (usually low rainfall and a long dry season. Only about 25% and 28% of all land in Grenada and Carriacou, respectively, is considered suitable for cultivation (tillage) a total 9,490 ha (18,500 ac) in Grenada and 931 ha (2300 ac) in Carriacou. However, the vast majority of these cultivable lands (for example, 81% in Grenada) are actually in Class 3 and thus have strong limitations to their use. Given that terrain in Class 3 has mainly D slope[s] of 10-20%, it can be assumed that erosion risk is the most common limitation.
2.4 > 2. 2.5 Natural HazardsVolcanic Activity A submarine volcano, 160 m below sea level, is located about 7 km north of David Point, Grenada. This volcano, called Kick em Jenny is one of the most active in the Lesser Antilles, having erupted at least 8 times this century, and some scientists believe it may emerge above sea level during its next eruption. The last eruption occurred in 1977. Earthquakes Hurricanes and Other Storms Records show that between 1901 and 1964, 21 hurricanes and tropical storms affected the country but only one hurricane since the turn of the century has passed directly over Grenada. The most recent hurricane to strike Grenada was Janet, which caused major destruction in 1955. The hurricane produced winds of up to 130 mph and killed over 100 persons. Hectares of banana, nutmeg, and cocoa and forests were destroyed, while millions of dollars worth of wind and flood damage to property and infrastructure facilities. In order of decreasing impact, the major causes of damage from most hurricanes are: flooding from rainfall, coastal flooding and damage from storm waves, landslides and winds. Floods Landslides and Rockslides Control Methods adopted and their effectiveness The National Emergency Relief Organization is the agency responsible for the preparation of a National Disaster Plan and mobilisation of the countrys human and material resources in planning, training and managing various aspects of a disaster preparedness. A National Disaster Plan was prepared in 1985 but is now out of date. The Plan has never been fully exercised nor tested for effectiveness or response time.

3.1 HydrographyWater resources Approximately 52% of the population receive private water services, 23% use public standpipes, and 22% use rainwater catchments, private springs, streams or ponds. There are, at present, 29 water supply facilities in Grenada; twenty three (23) surface water and 6 groundwater. These facilities provide a total supply capacity of about 7 million gallons per day (gpd) in the rainy season. There are 8 major watersheds on Carriacou. Carriacou and Petit Martinique have no important permanent streams or springs. Household water supplies in these islands depend upon catching rainwater and storing it in cisterns, while water for agriculture and livestock comes mainly from withdrawal of groundwater and surface water stored in ponds. Water use by sector and trends Tentative estimates of the current agricultural water demand are in the neighbourhood of 15% of total demand (Weaver, 1989). While cocoa, bananas, nutmeg and sugarcane do not require irrigation during the dry season, under GOGs agricultural diversification effort, the production of new vegetable crops which do not require dry season irrigation is increasing, and there is potential for further expansion of vegetable production in flatlands in the east and south of Grenada. Surveys have shown that there is good groundwater potential in the Beausejour, Tempe-St. Johns, Woodlands, Chemin, Bailles Bacolet and La Sagesse river valleys in Grenada. There are plans to increase groundwater production by the construction of several new bore-holes in these areas in the near future. Some groundwater is already produced from wells in the Tempe-St. Johns Valley, Chemin Valley and Woodlands Valley. If wastage is not reduced below present levels, overall water demand for Grenada will be about 8.3 m gpd in 1997. Under the assumption that long-term wastage prevention programme will reduce wastage to 25% by the year 2000, overall water demand is projected to be only about 7 m gallons at that time; the slow growth in projected demand is due to the combination of reduced wastage and low projected population growth. If currently proposed production facilities are implemented, island-wide wet season supply will be about 8.7 m gpd in 1997. Dry season capacity in 1997 will reach about 8 m gpd, somewhat short of demand if wastage continues at a constant 40% of supply but more than adequate to meet projected island-wide demand if an effective waste reduction programme is realised. Of this, an estimated 1.7 m gpd (21%) will be produced from groundwater, and the rest from surface water sources (Waal, 1987). In the dry climate of Carriacou and Petit Martinique, an adequate water supply is highly dependent on the timely arrival of the rainy season. Estimates of the water resource availability in Carriacou were made for a 100 Day Critical Period (100 DCP), corresponding to roughly the last 3 months of the dry season. Mentes study indicates that the total sum of water available in Carriacou during the 100 DCP (summing up rainwater, surface and groundwater) is about 9.5 m gallons. Of this total, about 6 m gallons (62%) is groundwater, 3 m gallons (32%) is water in cisterns, and a little more than ½ m gallons (6%) is stored surface water. Rainwater catchments are the most widely distributed type of water supply system, followed by dug wells. Most dug wells are sited along the coast; there are also 3 drilled wells (now in disrepair) and 3 perennial ponds. Existing water demand in Carriacou is about 60,000 gpd; 30,000 is used for human consumption and the other half is needed for livestock watering. The present rate of water consumption is estimated at about 10 g per person per day. Available water storage capacity in the rainwater catchments can just meet the 100-day minimum requirement for dry season demand from the present human population, but the water available from ponds and dug wells can meet only 80% (80 days) of demand from the livestock. Carriacous potential water demand has been estimated at about 1.85 m gpd for the next 5-10 years; 95% of this potential demand will be needed for irrigation in the rural areas. The assumptions used in predicting potential water demand were that:
3.1 > 3. 3.2 Irrigation and drainageIrrigated agriculture is largely undeveloped in Grenada. The irrigation potential has not been quantified and though there is water available from a number of surface and groundwater sources, these sources have not been tapped nor is the extent of this resource known. Currently 218.5 ha, or 1.5% of the total land area under cultivation, is under irrigated compared to 4.8 ha in 1973. The micro irrigation technique is utilised in more than 90% of all irrigated land areas, with the remaining area under sprinkler irrigation. Cost for sprinkler and micro irrigation systems are US$6,175 and US$8,645/ha respectively. Of the agricultural areas irrigated, less than one percent
is sourced from river diversion, 6.5% from reservoirs, while the remainder
is sourced from the direct pumping of rivers. One limiting factor to
the development of irrigation in Grenada is that significant amounts
of arable land are located in areas where there is no available water
source, domestic or otherwise. Costs of sprinkler and micro irrigation
systems are US$6175 and US$8645 /ha respectively. Institutional environment Trends in water resources and irrigation development, constraints to development, institutional changes, and perspectives. There is just one example of the a growing recognition in the importance of irrigation of Grenada's agricultural sector. Within the banana industry, investment in irrigation is being encouraged, with the recognition of a potential average yield increase to 25t/ha under irrigation, compared with 17t/ha in non-irrigated plantations. Similarly, attempts to encourage a more diversified agricultural product have resulted in a number of large estates being subdivided and made available to small farmers. As these farmers increasingly move into vegetable and cut flower production, this will necessarily create a greater need for supplement irrigation to ensure year round productions. 3.2 > 3. |
4. Plant nutrient resources4.1 Plant nutrient use and trends 4.2 Fertilizer production and costs 4. > top |
4.1 Plant nutrient use and trendsIn Grenada all Fertilizers consumed are imported. Although
on a declining trend during the last 6 years the total import of fertilizers
in Grenada lies within the range of 1800-3600 MT (product) per annum.
In 1989, for example, the total imports reached more than 3600 MT, compared
with 1800 MT in 1995. Until 1992 a number of different fertilizers were
imported, mainly different types of NPKs. Since 1992, however, almost
all the imports have been limited to two types of NPK, namely 16-8-24
(+2MgO) imported by Grenada Banana Co-operative Society, (recommended
for banana) and 12-27-16 imported by Grenada Cocoa Association, (recommended
for cocoa). The demand for fertilizers is spread all over the year with two peaks (May-August) and (November-January). The potential fertilizer consumption has been estimated at approximately 4200MT/year: 2200 MT for cocoa, 725 MT for banana, 145 MT for sugarcane, and 1150MT for vegetables. However, local availability of fertilizers is very inconsistent. The result is farmers generally using whatever fertiliser is available. The procurement of fertilizers is dependent on demand, but is also dependent on the importers' access to sufficient financial resources. At present, the quantities imported seem to be insufficient to cover the present demand, especially for banana fertilizers. There are indications that the types of NPKs currently used as well as the rates recommended have not been tested for their suitability to local soil and environmental conditions thus not supporting optimum yields and best economic returns. Only recommendations for cocoa have actually been tested in Grenada, while others are based on findings from neighbouring countries. 4.1 > 4. 4.2 Fertilizer production and importsIn January 1995, the Government requested FAO for assistance in the improvement of plant nutrition management and of the fertilizer sector. The assistance was approved and the agreement signed on March 1995 under FAOs Technical Cooperation Programme, project TCP/GRN/4552, Improvement of Fertilizer Procurement, Distribution and On-Farm Price for the Increase of Small Farmers Income, with a budget of US$294,000. The Land Use Division of the Ministry of Agriculture
(MOA) was the Government Agency responsible for project implementation.
The project activities started on May, 4 1995, and ended on 30 October
1996. The project staff recruited from the CTA comprised of one agronomist,
a specialist in Fertilizer Procurement (12m/m), one international consultant,
Expert in Fertilizer Cost and Pricing (6 weeks) and one international
consultant, Expert in Fertilizer Logistics and Port Equipment (6 weeks).

5.1 Land-related constraintsLandfills: Properly constructed landfills are required to replace the open dump sites. This should be followed by closure of all previously approved and informal open dump sites. It is recognized that properly designed landfills sites are necessary to serve the islands. However, because of the shortage of suitable land away from existing residential developments, procurement of a suitable site may be problematic. In rural areas it is uneconomical to maintain and operate separate landfills because of the small volume of garbage generated. Other appropriate technologies should be pursued at these locations (See Photo 5.1.1). Coastal Erosion: Coastal erosion was also considered to be an issue of serious concern. Though it was noted that some of that is as a result of natural processes, it is also believed that sand mining is the most identifiable cause of coastal erosion. In the absence of a suitable alternative source of fine aggregate and with the growing demand for sand in an expanding economy, the problem is not expected to be resolved in the near future (See Photo 5.1.2). Most of the Western coastal reefs are covered with solid waste, debris, old vehicles etc. There have also been sightings of reefs being smothered with silt. The main causes of these problems are related to inland development activities, particularly in the building and agricultural sectors, where erosion and other activities pollute the streams and other waterways which lead to the sea (See Photo 5.1.3). Other land-related constraints:
5.1 > 5. 5.2 Water-related constraintsWaste Disposal at Sea: Commercial shipping and cruise ships plying the countrys sea lanes must either dispose of their solid waste in port or at sea. Failure to provide such facilities at ports, increase the probability of disposal of such waste at sea, with the resulting deleterious effects on the marine environment. Port reception and disposal facilities are to be put in place. Wastewater Management: The Government of Grenada intends to implement a policy to ensure that all wastewater is disposed of in a sanitary manner. The operational problems associated with this policy is that less than 7% of all water customers are metered. Even after the connections to the sewerage system was made mandatory, very few of those customers were metered. Encroachment within water catchment areas: The increasing demand for land for agriculture has resulted in many small farmers entering forested areas and clearing lands for small farming. Such encroachments result in deforestation, soil erosion, and pollution of streams, rivers and coastal waters (See Photo 5.2.1). Overfishing: The issue of major concern
to the authorities responsible for the management of coastal resources
is overfishing, particularly of reef fisheries and other exotic species
such as Conch and Lobster. Other water-related constraints:
