Fiji is a country in the South Pacific Ocean composed of 332 islands of which only 110 are inhabited. The country has total area of 18 270 km². The two major islands, Viti Levu and Vanua Levu, with total areas of 10 429 km² and 5 556 km², represent 57 percent and 30 percent of the total area of the country respectively. Two smaller islands, Taveuni with a total area of 435 km² and Kadavu with a total area of 408 km², account for a further 4.6 percent of the land area, and most of the remaining islands are very small. For administrative purposes, the country is divided into 14 provinces and 1 dependency (Rotuma). The capital city is Suva.
The agricultural area, which is the sum of arable land, permanent crops and permanent meadows and pasture, is estimated at 425 000 ha, which is 23 percent of the total area of the country. In 2013, the total physical cultivated area was estimated at 250 000 ha, of which 66 percent (165 000 ha) consisted of temporary crops and 34 percent (85 000 ha) of permanent crops (Table 1).
The islands form a group of high islands of volcanic origin, with barrier reefs, atolls, sand cays and raised coral islands. Both Viti Levu and Vanua Levu are mountainous, with peaks rising to 1 323 m and 1 032 m above sea level respectively. The uplands of both islands were formerly covered in tropical rainforest, but much of this has now been replaced with secondary forest and grassland on the lower slopes. Farmland occupies most flattish lowland, and large areas on both islands are under cultivation for sugarcane. In fact, more than half of the cultivated area consists of three crop types only: coconuts (26 percent), sugarcane (17 percent), roots and tubers (10 percent) (FAO, 2015).
The different geological origins and climates of the islands and their isolation from other islands have all contributed to provide Fiji with a large number of different ecosystems with a very rich diversity of flora and fauna (SOPAC, 2007).
Fiji has a tropical marine climate. The wet and tropical cyclone season are from November to April. The dry season is from May to October. Only 20 percent of the rain falls during this period, unevenly distributed over time and location. The average annual temperature in the country is 27°C, while the highest temperature is 32°C and the lowest temperature 18°C (WAF, 2015). Average annual rainfall ranges from 1 500 mm on the smaller islands to over 4 000 mm on the larger islands.
In 2015, the total population was about 892 100, of which around 46 percent was rural (Table 1). Population density is 49 inhabitants/km². The average annual population growth rate in the 2005-2015 period was 0.8 percent. The two major islands, Viti Levu and Vanua Levu, account for 87 percent of the population (WAF, 2015). The two major urban areas are Nadi and its peri-urban area in the west of Vita Levu and the Suva-Nausori corridor in the southeast of Viti Levu (SOPAC, 2007).
In 2014, the Human Development Index (HDI) ranks Fiji 90 among 188 countries, while the Gender Inequality Index (GII) ranks it 87 among 155 countries, for which information was available. Life expectancy is 70 years and the under-five mortality is 22 per 1000 births, both progressing from 66 years and 27 per 1000 in the 1990s. With no significant distinction between boys and girls, around 97 percent of the children in 2012 are enrolled in primary education and 83 percent in secondary education (World Bank, 2015). In 2015, 96 percent of the population had access to improved water sources (100 and 91 percent in urban and rural areas respectively) and 91 percent of the total population had access to improved sanitation (93 and 88 percent in urban and rural areas respectively) (JMP, 2015).
In 2014, the gross domestic product (GDP) was US$ 4 030 million and agriculture accounted for 12 percent of GDP, while in 1994 it accounted for 21 percent.
Subsistence farming and sugarcane production have traditionally been the pillar of Fiji’s agriculture. Over the past ten years, these subsectors have shrunk while the shares of other crops, livestock, and the public sector have increased. The “other crops” subsector is mainly driven by the root crops and horticulture industry.
Fiji’s export of sugar, fish, crude coconut oil, root crops, and horticultural crops is facing international competition. The country is still importing many of its basic food requirements such as rice, meat and milk. The country’s transformation from subsistence to commercial agriculture is slow. The government is working to generate the fund and attract investment necessary to finance the modernization of Fiji’s agriculture (MoA, 2014). The Ministry of Agriculture identifies fruits and vegetables amongst the priorities for export promotion (Fink et al, 2013).
Beef and dairy production dominates the livestock subsector. Both industries have been in decline in the past decade due to low private sector investment, diseases, and poor quality breeding and milking stock.Pork, poultry and goat production, on the other hand, have performed reasonable well (MoA, 2014).
In recent years, a strong tourism industry has driven the economic growth in Fiji (PACC, 2015).
Fiji’s islands have considerable differences in their water resources. The large islands are mountainous and have significant permanent surface water sources, while many small islands with low elevation have little or no permanent surface water and rely on groundwater and rainwater only.
The major river on Viti Levu is Rewa river which originates in Tomanivi, the highest peak in Fiji, and flows southeast for 145 km to Laucala Bay, near Suva. The Rewa river is fed by two large tributaries, the Wainibuka and the Wainimala. Other important rivers on this island are the Nadi, Navua, Ba, and Sigatoka. The main river on Vanua Levu is the Dreketi river.
Total renewable surface water resources are estimated at 28 550 million m³/year. The renewable groundwater resources are estimated at about 5 273 million m³/year, which are considered to be drained entirely by the surface water network (overlap). The total annual renewable water resources in the country are thus estimated at 28 550 million m³ (Table 2).
There are no important natural lakes in Fiji.
The most important dam in the country, constructed to produce hydroelectric power, is the Monasavu dam on the Nanuku river. It was completed in 1983 with a total capacity of 133 million m³. It is located just above the Monasavu Falls. Water from the dam is diverted through nearly 5.4 km of tunnels to the Wailoa Hydro Power Station on the Wailoa river, which supplies up to 60 percent of the country’s energy needs.
The Nadarivatu dam, also known as the Korolevu dam, is located on the upper reaches of the Sigatoka river and has a total capacity of 36 000 m³. The dam diverts water from the Sigatoka river through a 3 225 m long tunnel to a power station along the Ba river to the southwest. The power station was commissioned in 2012.
The Vaturu dam, in the drier west of Viti Levu, has some small hydroelectric energy generation benefits.
In 2015, total dam capacity in the country is estimated at 133 million m³ (Table 2).
In 2005 total water withdrawal was estimated at 84.9 million m³, of which 50 million m3 (59 percent) was for agriculture, 25.3 million m³ (30 percent) for municipalities and 9.6 million m³ (11 percent) for industries (Table 3 and Figure 1).
Surface water is the main source of water supply for all major towns on the larger islands of Fiji that have higher elevation, as well as for industrial and irrigation uses. Groundwater use in large islands is primarily for rural water supply and for increasing some town water supplies. In recent years, some industries have begun to exploit groundwater.
Surface water availability is a problem in some islands with low elevation, which rely exclusively on groundwater and may or may not attempt to use rainwater. Rainwater harvesting using roof catchment systems with a communal standpipe are very popular in rural Fiji. Because of high annual rainfall, installed storage tanks are normally small and do not yet take into account the possibility of extreme climate events and drought.
One commercial use of groundwater has been the water bottling for export that has attained considerable political and public attention (SOPAC, 2007).
In 1998, the area equipped for irrigation was equal to 3 000 ha. In 2003, it was estimated at 4 000 ha, of which 90 percent was irrigated by surface water and the remaining 10 percent by groundwater (Table 4 and Figure 2). Of this area of 4 000 ha, around 3 000 ha or 75 percent is dedicated to rice. The remaining 1 000 ha or 25 percent are upland crops, the majority of which are irrigated by sprinkler systems using both surface water and groundwater resources (Table 4 and Figure 3). It is estimated that all the area equipped for irrigation is actually irrigated.
According to the Ministry of Agriculture (MoA), there is no need to increase the existing rice production areas in Fiji for the country to become self-sufficient in rice. It can be reached through the rehabilitation of existing irrigation systems (MoA, 2014).
In 2014, MoA initiated a project in the Nadroga and Navosa province that should boost potato production in Fiji. The project covers about 64 ha (Chaudhary, 2015).
Several national and local institutions are involved in water resources management:
The Pacific Islands Applied Geoscience Commission (SOPAC) is an intergovernmental, regional organization including 18 Pacific island countries and territories, as well as Australia and New Zealand. SOPAC’s work is carried out through its Secretariat, based in Suva. While the initial focus of its work was on marine mapping and geosciences, during recent years other scopes such as hazard assessment and risk management, environmental vulnerability, oceanography, energy, water and sanitation have been included.
An inadequate legislation, a lack of detailed policy, a lack of coordination and a serious deficit of technical and scientifically qualified staff are a barrier for the implementation of integrated water resources management (IWRM) in Fiji (SOPAC, 2007).
Some conflicts have occurred between different water sectors in some basins, such as the Sigatoka basin. The conflicts arise in part because there is no coordinating mechanism to ensure water use for the different sectors, and especially the agriculture and irrigation sector. Coordinating between the different sectors should be improved, including measures for dealing with low flow and drought conditions, where priorities need to be allocated among various conflicting water users (SOPAC, 2007).
The key political groundwater management issue in Fiji has been the abstraction of groundwater for bottling and export by a private enterprise. There have been conflicts over the potential of other bottling enterprises (SOPAC, 2007).
The Nadi river has been subjected to severe flooding over the past few years, resulting in significant damage. Thus, the Nadi basin has been identified as the first priority for an IWRM demonstration project in Fiji. The basin is an immensely valuable resource for Fiji and sustains the agricultural, drinking water, forestry, and tourism sectors. A catchment management plan to address some of the causes of flooding (e.g. inappropriate land use or tree clearance) has been implemented, which is providing direct protection for the communities affected (UNDP, 2015b).
There are no water charges in Fiji. The water infrastructure installed by government. Once commissioned and operational, the users are responsible for its operation and maintenance.
No overall national policy or legislation that deals with water, its uses and IWRM exists. However, there is a number of jurisdictions related to different aspects of water use and management:
Groundwater is however presently not covered under any specific legislation.
The quality of water in the major rivers and streams is believed to be good, although data are not organized or coordinated. Human activities have affected water quality over the years and sources of pollution are industry, forestry and agriculture, as well as the growth of urban areas. This pollution damages native fisheries and aquatic life in streams and rivers.
Very little data is available for the assessment of groundwater quality. Groundwater may be polluted by the infiltration of chemicals, which are disposed by the sugarcane farmers and other agro-producers. On larger islands groundwater contamination is a major source of concern, but also on smaller islands some problems may occur due to local waste disposal that may pollute groundwater. (SOPAC, 2007).
A close connection exists between waste disposal, water quality and health, especially in rural areas. The most common waterborne diseases in the country are leptospirosis, diarrhoea, dysentery and typhoid (SOPAC, 2007).
Water Authority of Fiji has 43 water treatment plants and facilities throughout the country providing safe and clean drinking water (WAF, 2015).
Fiji has experienced both drought and flooding. Regular drought results from El Niño climate conditions and low-lying islands are particularly susceptible to extended dry periods. Flooding regularly occurs throughout various parts of the country, where some larger towns including Nadi, Ba, and Labasa have developed in highly flood prone areas. Development of agriculture in the floodplain and progressive deforestation for agricultural purposes may cause flood peaking to become more extreme in the future.
Fiji recognizes the importance of improving water management in the country. The implementation of IWRM requires a number of features to be developed simultaneously (SOPAC, 2007):
