Geography, climate and population
Azerbaijan, with a total area of 86 600 km2, is located on the southeastern slopes of the Caucasus Mountains. It is bordered to the east by the Caspian Sea, to the south by the Islamic Republic of Iran, to the southwest by Turkey, to the west by Armenia, to the northwest by Georgia and to the north by the Russian Federation. The Nakhchivan Autonomous Republic of Azerbaijan in the southwest is separated from the rest of the country by Armenia.
About 43 percent of the area of Azerbaijan is situated more than 1 000 m above sea level. The country can be divided into five main physiographic regions:
The cultivable area is estimated to be about 4.32 million ha, which is 50 percent of the total area of the country. In 2005, the cultivated area was 2.06 million ha, or 48 percent of the cultivable area, of which 1.84 million ha were annual crops and 0.22 million ha permanent crops (Table 1). Between 1993 and 2005 the cultivated area increased by 15 percent.
Azerbaijan is situated on the northern edge of the subtropical zone. Its climatic diversity is the result of its particular geographical location and landscape, the proximity of the Caspian Sea, the effect of sun’s radiation and air masses of different origin.
The climate in Azerbaijan is continental. The weather in the lowlands is arid, with average summer temperatures of over 22 °C. In the mountain regions, temperatures can fall below 0 °C in winter and in Nakhchivan severe frost may occur. Humid tropical weather prevails in the coastal zone near the Caspian Sea, mainly in the Lankaran lowlands in the southeast. The estimated average precipitation is 447 mm/year.
The total population is 8.4 million (2005), around 50 percent of which is rural. The average population density is 97 inhabitants/km2.
In 2006, 80 percent of the population had access to improved sanitation (90 and 70 percent in urban and rural areas respectively) and 78 percent had access to improved water sources (95 and 59 percent in urban and rural areas) (Table 1).
Economy, agriculture and food security
Agriculture plays an important role in the Azerbaijan’s development and in guaranteeing the supply of staples and constitutes one of the main sectors of the economy.
In 2007, the Gross Domestic Product (GDP) was US$31.3 billion. The share of agriculture dropped from 39 percent in 1990 to 6 percent in 2007, due to extensive industrial development from 1995 to 2004. Production sharing agreements with large foreign companies regarding oil and gas fields have led to the rapid development of these industries.
In 2005, the total economically active population was 3.98 million, or just over 47 percent of the total population, with some 25 percent employed in the agricultural sector. Women make up about 52 percent of the rural labour force.
Plant cultivation is one of the key sectors of agriculture in Azerbaijan. Its fertile lands, good climate and topography provide opportunities for the production of agricultural products year-round (Heydar Aliyev Foundation, 2008). The most important crops are wheat, cotton, potatoes, vegetables, tobacco, melon, sugar beet, sunflowers and fruit trees.
It is estimated that internal renewable water resources amount to about 8.12 km3/year (Table 2). Annual surface runoff is estimated at 5.96 km3 and groundwater recharge at 6.51 km3, of which 4.35 km3 constitutes the base flow of the rivers. The estimated incoming surface flow is 25.38 km3/year, of which 11.91 km3 from Georgia, 7.50 km3 from the Islamic Republic of Iran and 5.97 km3 from Armenia. The Sumar River, with a total flow of 2.36 km3/year, forms the border between Azerbaijan and the Russian Federation. The total renewable surface water resources (RSWR), including incoming and bordering flows, are therefore estimated at 32.52 km3/year. In the case of the Kura and Araks Rivers, which flow through Turkey, Georgia, Armenia, the Islamic Republic of Iran and Azerbaijan, discussions are under way on a water sharing agreement.
The groundwater resources are famous for their quality as mineral drinking water and are also used for medical purposes. The Nakhchivan Autonomous Republic is especially rich in mineral groundwater.
Azerbaijan has four major river basins, two of which are international:
The total reservoir capacity of Azerbaijan’s dams is around 21.54 km3. Most of this capacity, 21.04 km3, comes from large dams, of more than 100 million m3 each. The four largest reservoirs are the Mingacevir and Shamkir on the Kura River, the Araks dam on the Araks River, and the Sarsang on the Terter River, in Armenia.
In 2005, wastewater production totalled some 659 million m3. Most wastewater is produced by the cotton cleaning, cotton oil production, fish-curing and grape processing industries. In 2005, 161 million m3 of wastewater was treated for reuse (Table 2). Although wastewater treatment plants exist in 16 towns and cities, the majority are partly or completely out of operation.
International water issues
Azerbaijan is party to three agreements with its neighbours on transboundary rivers: with the Islamic Republic of Iran on the Araks River, with Georgia on Gandar Lake and with the Russian Federation on the Samur River. No agreement exists regarding the Kura River, the most important transboundary river in the region (UNECE, 2004). Issues of critical importance are the sharing and joint management of the Kura and Araks Rivers and of the Caspian Sea to prevent further pollution and ensure sustainable development of their resources.
In 1997 the Government of Georgia ratified an agreement with Azerbaijan concerning environmental protection, providing for cooperation in the creation of specifically protected areas within transboundary ecosystems.
The Caucasus Initiative, launched by the German Ministry of Cooperation and Development, envisages, among other things, the implementation of the “Ecoregional Nature Protection Programme for Southern Caucasus” covering the three Caucasus countries: Georgia, Azerbaijan and Armenia. It will be implemented in the nearest future and will facilitate to protect and sustainable use of water resources in the region (Tsiklauri, 2004).
A number of international organizations have cooperated on initiatives in Azerbaijan in the field of ecology through the UN mission and the UNDP. Negotiations have been held with representatives of the UN, UNEP, UNESCO, World Bank and environmental protection organizations of the USA, UK, Germany, Turkey, the Islamic Republic of Iran and CIS countries. One of the results has been the adoption of the “Agreement on cooperation in the field of ecology and environmental protection between Azerbaijan and Turkey” (UNEP/GRID-Arendal, 2005).
From 2000 to 2002, USAID, in collaboration with Development Alternatives Inc. (DAI), implemented the South Caucasus Water Management project. Its aim was to strengthen co-operation among water agencies at local, national and regional levels and demonstrate integrated water resources management. In parallel, between 2000 and 2006, the EU and the Technical Assistance Commonwealth of Independent States (TACIS) carried out the Joint River Management Programme on Monitoring and Assessment of Water Quality on Transboundary Rivers for the prevention, control and reduction of the impact of trans-boundary pollution. The programme covered four basins, including the Kura River Basin. In addition, regional organisations such as REC, Eurasia Foundation, and numerous local foundations have promoted national and regional activities concerning water resources management and protection (UNEP, 2002).
Between 2002 and 2007, NATO-OSCE realized the South Caucasus River Monitoring Project. Its general objectives were to establish the social and technical infrastructure for a joint international Transboundary River water quality and quantity monitoring, data sharing and watershed management system among the Republics of Armenia, Azerbaijan and Georgia (OSU, 2008).
The project Reducing Transboundary Degradation in the Kura-Araks River Basin, implemented by the UNDP Bratislava Regional Centre in collaboration with the Global Environmental Facility (GEF), has involved four of the basin countries: Armenia, Azerbaijan, Georgia and the Islamic Republic of Iran. Efforts are being made to involve Turkey in the project as well. The preparation phase, which is co-funded by Sweden, began in July 2005 and will last 18 months. The objective of the project is to ensure that the quality and quantity of the water throughout the Kura-Araks River system meets the short and long-term needs of the ecosystem and the communities that rely upon it. It will be achieved by fostering regional cooperation, increasing the capacity to address water quality and quantity problems, demonstrating water quality/quantity improvements, initiating required policy and legal reforms, identifying and preparing priority investments, and developing sustainable management and financial arrangements.
Currently there are no water treaties between the three south Caucasian countries owing to the political situation in the region. Nagorno-Karabakh is one of the main obstacles, making it difficult for Azerbaijan and Armenia to sign a treaty even one only relating to water resources management (Berrin and Campana, 2008).
In 2005 water withdrawal was estimated at 12.21 km3, of which 76.4 percent for agricultural purposes, 4.2 percent for municipal uses and 19.3 percent for industrial processes (Table 3 and Figure 1).
In 2005, freshwater withdrawal totalled 12.21 km3. It was estimated that primary surface water accounted for 92.6 percent, primary groundwater for 6.1 percent and reused treated wastewater for 1.3 percent (Figure 2).
Irrigation and drainage
Evolution of irrigation development
The irrigation potential is estimated at 3.2 million ha. In the last century, irrigation was concentrated alongside the rivers and it was only at the beginning of this century that the construction of large irrigation canals started. In 1913, 582 000 ha were irrigated. The most intensive development took place after the Second World War and in 1975 the area equipped for irrigation was 1.17 million ha. By 1995 this had become 1.45 million ha, which is 45 percent of the irrigation potential.
In 1995, the total length of all irrigation canals was 65 900 km, of which only 2 400 km, or 3.6 percent, were concrete canals. National irrigation efficiency was estimated at 55 percent. The largest canals are the Upper Garabakh, the Upper Shirvan and the Samur-Apsheron, all earthen. The Upper Gabarakh canal runs southeast from the Mingacevir reservoir to the Araks River. It is about 174 km long and has a capacity of 113.5 m3/s. About 85 000 ha were irrigated by this canal in 1995. The Upper Shirvan canal also starts from the Mingacevir reservoir and runs east to the Akhsu River. It is about 126 km in length and has a capacity of 78 m3/s and in 1995 irrigated about 91 100 ha.
In 1995, almost 90 percent of the irrigation was surface irrigation, mainly furrow and border strip irrigation. Sprinkler irrigation and localized irrigation were used mainly on perennial plantations and vineyards (Table 4 and Figure 3). Surface water was used on 93 percent of the area, mainly from reservoirs and through direct pumping in rivers and canals (Figure 4). About 96 700 ha were irrigated by groundwater through more than 5 000 wells. Private farmers exploit this source intensively as the major irrigation installations are seriously degraded.
In 1995, small schemes (<10 000 ha) covered 5.3 percent of the total area equipped for irrigation, medium size schemes (10 000–20 000 ha) 13.3 percent and large schemes (>20 000 ha) 81.5 percent (Figure 5). Most schemes were state-owned. Farmer-owned irrigation started to appear in 1992 and in 1996 represented 1 percent of the area.
In 2003, the total area equipped for irrigation was about 1 426 000 ha and the power-irrigated area was estimated at 479 249 ha.
Role of irrigation in agricultural production, the economy and society
In 2004, the harvested irrigated area was 1 391 521 ha. Annual crops represent 93 percent of this area and permanent crops 7 percent. The main irrigated crops are wheat (44 percent), barley (11 percent), cotton (5.6 percent) and vegetables (5.6 percent), while the most important permanent crops are tea, bananas, olives, grapes and strawberries (Figure 6).
Status and evolution of drainage systems
The total drainage network covers 608 336 ha, all in the areas equipped for irrigation. In more than half the drained area the installations need to be renovated. In 2003 the area salinized by irrigation was estimated at 635 800 ha (Table 4).
Water management, policies and legislation related to water use in agriculture
The main institutions involved in water management are all state institutions. They are:
The rehabilitation of irrigation and drainage systems to ensure the sustainability of the subsector remains a priority. Major policy changes in land ownership and irrigation management play an important role in improving irrigation performance.
Control of erosion is another major issue as, according to the Ecological Committee’s data, this problem affects almost 43 percent of the country. Effective measures to combat water erosion are the creation of a wood belt to protect fields, as well as wood belts along the banks of large rivers, canals and reservoirs.
There are several problems affecting the irrigation infrastructure (UNECE, 2004). They include:
As a result of recent efforts to improve the situation, institutional mechanisms have been established for the collection and use of water charges and the transfer of responsibility to water users. It is estimated that 40–45 percent of the irrigation infrastructure is in need of renovation. The inefficient use of water and the heavy water losses in irrigation represent major problems for water resources and soils.
Since 1997 water used for agricultural purposes is chargeable. Rates were changed in June 2003. The fee is charged for technical-operational costs and not for the use of water as a natural resource.
Charges on wastewater discharge were also introduced in 1992. The rates are very low, as is the collection rate, making the charge system less effective (UNECE, 2004).
The Presidential Decree of 23 October 2004 authorized the establishment of a public corporation “Agroleasing” and a series of measures to develop leasing in the agricultural sector. It was decided to provide AZM100 billion and 150 billion from the state budget in 2005 and 2006 for Agroleasing’s activities (Heydar Aliyev Foundation. 2008).
Policies and legislation
The water sector is regulated by the following legislation:
The Water Code is the basis for water management in Azerbaijan and sets out the following main principles for use and protection:
The Law on Water Supply and Wastewater sets the legal framework for this sector.
The Law on Amelioration and Irrigation regulates the planning, design, construction and operation of amelioration and irrigation systems. Accordingly, design and construction activities require special permits (licences) and systems have to be certified with technical passports.
The Law on Environmental Protection identifies the legal, economic and social bases of environmental protection. It governs the use of natural resources, amongst which water, and protection against domestic and industrial pollution. The Law also sets the basis for economic mechanisms, such as payment for the use of natural resources and for the disposal of domestic and industrial waste and economic incentives for environmental protection.
In July 1996, a land reform law was adopted by the National Assembly (Milli Majlis), establishing private property rights to land. The land is to be transferred to all rural inhabitants free of charge. It can then be sold freely, exchanged, transferred by right of succession, leased or used as mortgage security.
In November 2003, the presidential decree “On intensification of the socio-economic development in the Republic of Azerbaijan” envisioned the start of the second stage of the agrarian reforms and the accomplishment of appropriate activities. It has been followed up by the state programme for socio-economic development of the regions of the Republic of Azerbaijan (2004-2008), adopted on 11 February 2004. The implementation of the programme will create the opportunities for radical changes and wider business development in agriculture. Among other activities, the state programme will restore agricultural processing enterprises, establish new production enterprises, increase the efficiency of local resources, build or modernize the infrastructure for regional development, step up the second stage of agrarian reforms, establish technical service centres in the region, and extend seed depots and other important activities (Heydar Aliyev Foundation. 2008).
Environment and health
Water losses in the irrigation distribution systems, estimated at 50 percent, cause waterlogging and salinization. Moreover, only 600 000 ha of irrigated land, the most naturally saline areas, have drainage. The increased water level of the Caspian Sea has also made land on the coast more saline. Salinization is particularly widespread on the Kura-Araks lowland (UNECE, 2004).
The rapid development of all spheres of economics and human activity has had an increasingly negative impact on the environment, partly due to the inefficient use of natural resources. Like many other countries, Azerbaijan is interested in finding solutions to the problems of environmental protection and rational utilization of natural resources. In support of the country’s environmental protection goals, a number of important laws, legal documents and state programmes, all conforming to European law requirements, have been approved.
Almost 30 percent of the Caspian Sea coastal area is exposed to contamination. More than half of the rivers more than 100 km long are considered to be contaminated. All the lakes of the low-lying parts of the country are exposed to the changes in the thermal, biological and chemical regimes. The lakes of the Apsheron Peninsula and the Kura Araks Lowland, covering a total area of more than 200 km2, are in a critical state. The main sources of contamination of water resources are industry, agriculture, the municipal sector, energy, heating and recreation (UNEP/GRID-Arendal, 2005).
Irrational use of water resources and pollution of water bodies can be put down to the fact that cities, regional centres and other human settlements are poorly equipped with sewerage systems and wastewater treatment facilities, as well as to the obsoleteness of the existing technical facilities. Untreated wastewater released from Baku, Ganja, Sumgayit, Mingacevir, Ali-Bayramli, Nakhchivan and other urban centres significantly contributes to the pollution of the water bodies.
Prospects for agricultural water management
Major positive factors in Azerbaijan’s environmental outlook include the enactment of new legislation and the signing of international conventions. Although economic development is not advanced, the country is moving slowly in the right direction for water resources management.
