Liberia, located in West Africa, covers an area of 111 370 km2. It borders Sierra Leone to the northwest, Guinea to the north, Cote d’Ivoire to the northeast and east, and the Atlantic Ocean to the south and southwest. Its north-south extent is about 465 km and its Atlantic Ocean coastline is about 520 km long. The terrain comprises mostly flat to rolling coastal plains, rising to rolling plateau and low mountains in the northeast. The coastline is characterized by lagoons, mangrove swamps, and river-deposited sandbars. The country can be divided according to elevation into four main physical regions parallel to the coast: i) coastal plains up to 100 m; ii) hills from 100 to 300 m; iii) plateaus from 300 to 600 m; and iv) mountainous areas above 600 m. In 2002, the cultivated area was estimated at 600 000 ha, of which arable land covers 380 000 ha, while 220 000 ha are covered by permanent crops (Table 1).
Liberia’s climate is tropical hot-humid. Winters are dry with hot days and cool to cold nights; summers are wet and cloudy with frequent heavy showers. The rainy season lasts from April to November and average annual rainfall is estimated at 2 391 mm, with a spatial variation from 2 000 to 5 000 mm. Although this is much higher than the quantity of water required for crop growth, an acute water deficit is experienced anyway during a 3 to 5 month period, particularly in the uplands.
Total population in 2004 was 3.5 million, of which 52 percent were rural. Population density was 31 inhabitants/km2.
Liberia is in a post-war period facing serious political, financial, administrative and organizational problems. Ten years of conflict have led to multiple internal displacements of hundreds of thousands of people, disrupted supply of basic social services, increased the vulnerability of women and children to extreme poverty, hunger, disease and HIV/AIDS. Poverty is widespread.
Access to education is limited. An estimated 80 percent of schools, health service structures, water wells and sanitation facilities have been either destroyed or abandoned since 1998. No up-to-date water supply and sanitation coverage data are available, but those still functioning are in alarming and worrying conditions in almost all counties in Liberia. As a result, morbidity and mortality rates remain high and may possibly deteriorate further as populations returning to these areas are expected to increase and thereby overstretch the already either only partly functioning or malfunctioning health and social infrastructures.
Before the outbreak of civil war, agriculture accounted for about 40 percent of GDP and Liberia had been a producer and exporter of basic products - primarily raw timber and rubber. The rubber industry generated over US$100 million export earnings annually. By the end of 1996, real GDP was as low as 10 percent of its pre-war level. However, from 1997 it increased, reflecting a post-war surge in rice, timber and rubber production, and in 2002, reached US$442 million. Nonetheless, in 2004, a still unsettled domestic security situation was slowing the process of rebuilding the social and economic structure of the country. In 2000, agriculture and forestry contributed over 90 percent of export earnings, mainly from rubber, timber, cocoa and coffee.
Agricultural activities are still considerably reduced and food insecurity is worsening, as the areas considered to be the "food basket" of Liberia are still inaccessible. Rice production in 1995 was only 23 percent of the pre-civil war level. Cassava production has also been falling, possibly by as much as 50 percent. Low productivity of land and labour, shifting cultivation and low livestock production remain the main characteristics of traditional farming in Liberia. Rainfed agriculture is the predominant system. Use of water control technology is exceptional and consists mainly of unregulated manual irrigation, using watering cans.
Liberia is far from being food self-sufficient, with net cereal imports and food aid as a percent of total consumption being 44.1 percent for the period 1998-2000. The variation in domestic cereal production between 1992-2001 (average percent variation from mean) was 44.5 percent.
Liberia can be divided into two kinds of river systems:
Internal renewable surface water resources are estimated to be 200 km3/year and internal groundwater is estimated to be 60 km3/year; all of the latter is believed to be drained by watercourses. Thus, the total internally produced renewable water resources become 200 km3/year, while an additional 32 km3/year comes from Guinea and Côte d’Ivoire, bringing the total renewable water resources to 232 km3/year (Table 2). Liberia is one of the African countries with the highest amount of renewable water resources per inhabitant: more than 71 000 m3/year.
Liberia shares rivers with all its neighboring countries:
Total water withdrawal in the year 2000 was estimated at 106.8 million m3. The main water user was agriculture with 60 million m3/year (57 percent), followed by municipalities with 30.4 million m3/year (28 percent) and industry with 16.4 million m3/year (15 percent) (Table 3 and Figure 1).
The irrigation potential in Liberia is estimated at 600 000 ha, consisting mainly of freshwater swamps. No up-to-date information on irrigated areas in Liberia is available. In 1987, the total water managed area was 20 100 ha (Table 4 and Figure 2), comprising:
FAO’s Special Program for Food Security (SPFS) 2000-2002 had the following aims:
The main irrigated crop is rice. It is grown in the swamps in addition to the upland rice. Shifting cultivation in the uplands is still the main technique: the secondary forest is cleared and burned, and upland rice is cropped during one or two years combined with different food crops (cassava, common groundnuts or vegetables). Afterwards, the area returns to bush fallow for 8-10 years. This system is the preferred mode of farming in Liberia and has the advantage of maintaining the ecological system in equilibrium. However, this system cannot be applied in areas where a higher population density prevents the restoration of soil fertility due to too short a fallow period. In those areas, swamp rice is cultivated in addition to upland crops.
While in the mid-1980s about 235 000 ha of rice were cultivated, this figure dropped to 120 000 ha in 2003, leading to a decrease in total rice production from about 290 000 tonnes in the mid-1980s to 110 000 tonnes in 2003. In 1995, the yield of upland rice was estimated to be 1.3 t/ha, while yields of swamp rice were about 1.6 t/ha, and yields in equipped wetlands and swamps reached more than 2 t/ha.
Gender and land tenure with regard to water management has been a well-known problem for projects in Liberia.
The National Water Resources and Sanitation Board was created in 1981 in order to coordinate the activities of the different institutions or corporations involved in the management of water resources. Before the conflict, the main institutions involved were:
Main environmental problems in Liberia are tropical rain forest deforestation, soil erosion, loss of biodiversity, and pollution of coastal waters from oil residue and raw sewage. Water-borne diseases such as diarrhoea, dysentery, cholera and infectious hepatitis are common.
With only about 3 percent or about 20 000 ha of a potential 600 000 ha of swampland cultivated with rice before the war, water control and soil management measures remain the most suitable vehicle for future development. Water deficiency in the dry season, poor drainage, flooding of lowlands and the hazard of water erosion are all problems that need to be addressed.
The development of swamp rice cultivation will become necessary with increasing population and population density. It has been estimated that with an intensification of swamp rice cultivation, it could be possible for Liberia to become self-sufficient in rice, which is the staple food crop. The urban demand for rice is also rapidly expanding.
Successful swamp rice production development in Liberia requires: i) application of improved swamp rice cultivation technologies; ii) high labour inputs, which can conflict with upland farming needs; iii) availability of modern inputs (improved cultivars, good quality seed, fertilizers); and iv) a change of mentality amongst farmers, who should consider rice as a means of increasing cash income and not just as a subsistence crop.
