4 LIVELIHOOD STRATEGIES IN SPATE-IRRIGATED AREAS

With crop returns being low even in good years and the likelihood of the absence or failure of a crop always there, spate-irrigated agriculture makes a precarious living. Farming households in spate irrigation systems have, therefore, adopted a number of livelihood strategies to cope with the uncertainties of spate-irrigated agriculture:

  • One strategy is to save the surplus of grains from a bumper year to a next year. A more common method to compensate bad years with good years is to monetise the surplus crop by investing in disposable property, such as livestock in general and draft animals in particular.
  • The most common strategy is the diversification of the household economy, whereby households in spate-irrigated areas generally depend on multiple sources of incomes. The co-existence of livestock keeping and spate irrigation has been noted in various arid regions. Small ruminants in particular are an integral component of the household production system and often serve as a buffer to overcome dry years.
  • Locally available natural resources often play an important role in satisfying various needs of many households.
  • Wage labour and off-farm activities are often other important sources of household income in spate-irrigated areas.
  • A failed flood season often triggers off substantial migration, in particular of able-bodied male family members, in search of labour.
  • Another strategy to survive an adverse year is borrowing money to purchase additional food items or to obtain seeds at the start of the cropping season.
  • Traditional mechanisms of solidarity and mutual assistance still play an important role in the local communities. (Van Steenbergen 1997)

The different livelihood strategies will be described and analysed in the following sections by using information about spate irrigation systems from Pakistan, Yemen, Eritrea, Ethiopia and Tunisia. The names of spate irrigation systems, which are used to illustrate certain aspects of livelihood strategies, are listed in Table 2 in Annex A.

4.1 Livestock

Livestock is an integral component of the livelihoods of most households involved in the cultivation of spate-irrigated crops as it is an important strategy to cope with the risks related to spate irrigation. The importance of livestock may be less if the probability of spate irrigation is relatively high or if there are good opportunities to generate an income outside the agricultural sector.

In general, livestock may have the following important functions in the livelihood strategies of households cultivating spate-irrigated crops:

  • Oxen and to a lesser extent camels are traditionally used for the preparation of the fields and the maintenance of the field bunds as well as the (re)construction of the diversion structures in the riverbeds and the cleaning of the flood canals.
  • Camels and donkeys are used for the transport of crop produce, water and people;
  • Cows, goats, sheep and poultry are raised as a source of food and income, whereby milk, dairy products (i.e. yoghurt, whey and butter), meat, wool and skins are the main livestock products, which are mainly used for home consumption but also sold to raise cash;
  • Small ruminants, such as goats and sheep, are important savings to cope with crisis situations because of their high reproductive rates and high degree of resilience to drought conditions, although oxen are also sold to bridge adverse years; and
  • Cattle, donkeys and camels provide dung, which is used as fuel by making dung cakes and as building material by mixing it with earth and straw.

Role of Oxen
The ownership of at least one pair of oxen is often an indicator of wealth. For many households in spate irrigation systems, it is difficult to support a pair of oxen, because the average farm size is often too small to produce sufficient fodder to feed them in years with normal floods. At times of drought, oxen and other large ruminants are a risk and many households do not have another choice to sell them or to move to other areas where fodder is available. Due to increasing farm mechanisation, the number of draught animals in spate-irrigated areas in Balochistan has reduced significantly, which has had consequences for the livelihoods of many households and the social organisation of the spate-irrigated communities. The sale of bullocks has lost its importance as a mechanism to cope with a crop failure or any other crisis. The replacement of bullocks by tractors has undermined the traditional organisation of system maintenance, whereby every household was contributing all its labour and animals for the (re)construction of the diversion structure and cleaning of the canal system in accordance with its capabilities. (Halcrow 1993a)

Oxen and draught equipment were commonly exchanged or hired in Wadi Rima (Yemen) as only 40% of the farmers possessed their own oxen. Hire charges for oxen may twice as high in the peak season than during the off-season. Farmers may work for owners of oxen in return for the use of the animals, usually at a rate of 3-day labour for one-day oxen hire. (MOD 1977a)

Composition and Number
The composition and number of livestock owned by households in spate-irrigated areas reflects their needs (i.e. traction, transport, food) as well as the local environmental conditions, including the availability of forage. In Wadi Rima, the stocking density of oxen is closely associated with cropping intensity. (MOD 1977a) A common strategy among livestock owners is to build up livestock numbers in anticipation of recurrent droughts, so that a minimum herd size is left after a crisis period. In the Shabwah Governorate in Yemen, an average household in the central-northern region owns 10 to 20 small ruminants, 5 to 10 camels and some poultry, whereas a typical household in the central parts possesses 20 to 30 small ruminants and some poultry. In Wadi Zabid, an average household has 2 cows, 2 calves, 5 goats and 4 sheep, while a minority of households owns two oxen. In the spate-irrigated areas of Wadi Rima, most households had on average 1.5 cows, 7.2 sheep, 1.5 donkeys and 6.4 hens, while about a quarter of the households had 2.1 oxen and about 40% had 3.4 goats. (KIT 2002; IIP 2002, MOD 1977a))

In the Sheeb area, about 30% of the farmers do not own bullocks and they have to rent of share a pair of oxen for the preparation of their fields. A typical household has 1.5 to 2.7 dairy cattle and 1 to 2 draught animals. (Hadera 2001) Only 31% of the landowners in the Yandafero scheme in Ethiopia have one or two oxen, whereas the other farmers hire or borrow draught animals or gain access through the exchange of labour. (Farm Africa 2003)

The number of livestock owned by an average household in spate-irrigated areas in Balochistan (Pakistan) varies considerably. In Chandia, Barag, Nal Dat and Marufzai, an average household owns 3 to 6 sheep, 5 to 9 goats, 1.5 to 3.5 cattle and 1 to 4 chickens, whereas one-third of the farmers in Chandia possess bullocks and a number of households in Barag and Nal Dat has a camel. (Halcrow 1993b-e) In other small spate irrigation systems, the number of livestock is considerably higher as 90% of the households in Toiwar have an average number of 62 small ruminants and two cows, whereas an average household in three schemes (i.e. Dudar, Sohar Khor and Sham) in Musa Khel District and one scheme (i.e. Jhalwani) in Barkhan District possesses 29 to 75 small ruminants and 2 to 10 large ruminants. (Halcrow 1998; Ahmad 1998)

The principle of sharecropping is also practiced in the livestock sector, whereby livestock owners place animals in the care of others in return of a proportion of the produce. In the D.G. Khan region and Balochistan in Pakistan, the herder receives 25% to 50% of all new born, surviving lambs and kids. (VBB Viak – NESPAK 1995, Ahmad 1998) Similar sharecropping arrangements for livestock also exist in Wadi Rima in Yemen, whereby the daily management and the costs of maintenance are the sharecroppers’ responsibility, for which he usually acquires half of the offspring and all of the milk in return. (MOD 1977a)

Small ruminants are usually grazed on the rangelands, whereas large ruminants are fed with green fodder and crop residue (i.e. straw and stalks) that are collected from the fields. In Wadi Rima, (store-damaged) sorghum grains are occasionally used for feed as well as surplus cotton seed and cakes, sesame cake and date waste. To cope with shortage of fodder in the vicinity of their villages, livestock-owners have to migrate with their animals to other areas, such as the highlands, where they can find sufficient fodder. In the Sheeb area (Eritrea), all livestock is kept in the village and fed with cut grass during the cropping season in order to prevent livestock from trampling and grazing young growing plant. (MOD 1977a, Hadera 2001, Nawaz 2003)

Revenues
Most households use their livestock products, such as milk, butter, yoghurt, whey, eggs, meat and skins, for home consumption, although some items may be sold locally to raise cash income. In the Sheeb area, an average household with two cows, two goats, one sheep and one chicken has an annual production of 625 litres of milk, 18 kg of butter and 130 eggs in a good year, whereas the production levels are 50% lower in a bad year. The incomes from livestock range from US$ 165 in a good year to only US$ 12 in a bad year. (Hadera 2001) Live animals are usually sold to repay outstanding loans and/or to purchase additional food items. In the spate-irrigated areas of the Shabwah Governorate, an average household generates a revenue between US$ 235 and 470 per year from livestock activities, including the sale of 5 to 15 sheep. (KIT 2002)

In addition to spate-irrigated agriculture and livestock, bee-keeping may be another important source of income for households in spate irrigation systems. Many households in the Shabwah Governorate, in particular in the spate-irrigated areas, are engaged in bee-keeping, of which 5% can be categorised as professionals with an average of 150 beehives, 10% as semi-professionals with about 50 colonies and the remaining 85% have a few beehives. It is estimated that small beekeepers could earn between US$ 60 and 295 each year, whereas professional bee-keepers have an annual income of US$ 3,000 and more. (KIT 2002) Bee-keeping is also an important secondary source of income among households in the Konso Special Wadera in Ethiopia, who are involved in spate-irrigated agriculture. (Farm Africa 2003)

4.2 Access to Locally Available Natural Resources

Spate water and land are two natural resources that are essential for the livelihoods based on spate-irrigated agriculture. However, there are also other locally available natural resources that play a very important role in the livelihood strategies of farming households in spate-irrigated areas.

Drinking Water
The access to reliable sources of (ground) water for potable and domestic purposes throughout the entire year is a condition for the permanent settlement of people in an area. In a number of spate-irrigated areas, however, (ground) water is not available permanently and the local population does not have another choice than to leave their villages in search of water for themselves and their animals. For instance, the majority of the local population in the Sheeb area (Eritrea) migrates each year for a number of months to the mountains, because there is not sufficient water for themselves and their animals in the lowlands during the summer months. (Hadera 2001; Halcrow 1997)

A similar situation also exists in the Kachhi Plain in Balochistan (Pakistan), where existing water sources could not supply sufficient water to satisfy the water requirements of the local population for the entire year. As a result, people have to migrate to other areas for a number of months each year. The most important sources for potable water are earthen tanks and low-level sites in the riverbeds. Most of these earthen tanks are located miles away from the villages and they often have insufficient storage capacity, which is further reduced to improper maintenance. To improve the access to potable water for the local population and to reduce the need to migrate temporarily to other areas, a number of newly designed water storage tanks have been constructed under the Pak-German Self-Help Project. The main improvement in the design of the water tanks is its increased depth in order to reduce water losses due to evaporation and seepage. As a result, the newly constructed tanks provide water for eight months, while the traditional tanks could not store water for more than three months. (BRSP 19??)

Due to the installation of an increasing number of tubewells for irrigation purposes, the aquifers in many spate-irrigated areas are seriously over-exploited. Due to this development, households in these areas have less secure access to potable water as the level of the water table is decreasing rapidly and an increasing number of shallow wells in the villages do not supply sufficient throughout the entire year. In addition, the quality of drinking water may be adversely affected as well as it becomes more saline.

Natural Vegetation
In a number of spate irrigation systems, trees play an important role in the livelihoods of the rural households as well. In the central-northern region of Shabwah Governorate in Yemen, each household has an average number of 25 to 50 Ziziphus trees in and around their spate-irrigated fields for bee-keeping, fodder, fruits, timber, fuel wood and medicinal uses. (KIT 2002) A large number of trees, such as acacia, can also be found in the command areas of spate irrigation systems in the Konso (Ethiopia), in which many beehives have been installed. In Pakistan, multi-purpose trees as the Tamarix are common in the spate-irrigated areas of Balochistan and Dera Ghazi Khan. In the Sheeb area in Eritrea as well as in the spate-irrigated areas along the Korakan River in Balochistan (Pakistan), households earn an income with the cutting and sale of (fuel) wood. The production and sale of charcoal is also undertaken by a number of households in Balochistan and the Tihama region in Yemen. (MOD 1977a, Hadera 2001; Halcrow 1993d, 1994)

Charcoal Production in Balochistan

In many spate-irrigated areas of Balochistan and Punjab (Pakistan), the dwarf palm is used by women for making different item, such as mats, ropes and sandals. (Ahmad 1998, VBB Viak – NESPAK 1995, Nawaz 2003) Trees with large spines, such as the acacia, are also used for the construction of fences around fields to protect standing crops from being damaged by roaming animals as well as to form corals where livestock is collected and protected for the night.

Furthermore, trees are also intensively used in the maintenance and repair of irrigation structures in traditional spate irrigation systems. Branches and even entire trees are used to strengthen diversion spurs as well as flood protection works. (Scheitz 1987) In Somalia, low dams of wooden poles are used to divert spate flows into the fields or to open ponds and pools for temporary storage. (Hag Nur 1987)

Use of Bushes for Strengthening of Diversion Spur in Eritrea

In addition to the cultivation of fodder crops, in particular sorghum, it is common that bushes and grass growing along flood canals and around the spate-irrigated fields are used to feed animals as well. Normally, small ruminants, such as goats and sheep, graze along the flood canals and the fallow fields in search of edible vegetation, whereby the herdsmen may sometimes cut branches of larger bushes, so that the animals can eat the (new) leaves. During the cropping season, it is not uncommon that women and children cut grass and take it home in order to feed their animals, which are kept within the compound as a measure to prevent damage to standing crops in the spate-irrigated fields.

Pasture
As livestock plays a crucial role in the livelihood strategies of households in spate-irrigated areas, access to sufficient fodder in terms of quantity and quality is conditional. In addition to the cultivation and/or procurement of (irrigated) fodder crops, such as (green) sorghum, and the use of leaves and grass found in the command area of the spate irrigation system, natural pastures are another important source of fodder for livestock. In Wadi Rima in Yemen, sheep and goats graze and browse for much of their feed along canal banks and on fallow fields and bushlands. In sparsely populated areas, such as Balochistan and the mountainous areas of Yemen, livestock owners may find pastures in the vicinity of their villages. In the Sheeb area in Eritrea and the Kachhi Plain in Balochistan, livestock owners have to migrate with their animals to the pastures in the highlands for several months each year due to shortage of fodder in the vicinity of their villages. (MOD 1977a, Hadera 2001, BRSP 19??)

In some (remote) areas of Balochistan (Pakistan), rangeland is communally owned by a tribe and their members have the right to use the resources from these communal lands, such as fuel wood, building materials, wild fruits, honey and edible roots. Outsiders can only graze their animals on the communally owned lands, if they have received permission and paid a grazing tax. In the Barkhan District, outside herders paid Rs 80,000 (US$ 2,330) to graze their 12,000 to 14,000 animals from October to March. In Marufzai, a total amount of Rs 45,000 (US$ 1,800) was raised in 1992 as grazing tax for the use of their communal rangelands by nomadic herdsmen. (VBB Viak-NESPAK 1995; Halcrow 1993d)

In particular in densely populated areas, over-grazing has seriously affected the quality of pastures, while more and more pastures are transformed in arable land for the cultivation of (rainfed) crops due to the increasing population pressure. As a result, livestock owners have to look for alternative sources of fodder for their animals, including the (seasonal) migration to the highlands and/or the use of cultivated fodder crops. However, these two options may not be affordable for poorer households and their only option may be the sale of most of their animals.

4.3 Wage Labour and Off-Farm Incomes

In addition to an income from spate-irrigated agriculture and livestock, households in spate-irrigated areas may have adopted the risk coping strategy to earn an additional income as labourers and/or from off-farm activities. Especially at harvesting time, most households have to hire additional labour as the available family labour is insufficient to carry out all the field activities. The available pool of wage labourers may comprise members of landless households, households with landholdings that are too small to sustain the household throughout the entire year as well as landholding households whose fields could not be irrigated during the last flood season. Wage labour is the second source of income for 25% of the households in the Toiwar scheme in Balochistan. Nomadic tribes and temporary migrants may also come to the spate-irrigated areas during harvesting time in search of wage labour. Wage labourers are often paid in kind, whereby they receive a fixed portion of the harvested crop. In Nal Dat, for example, wage labourers receive one-twentieth of the crop for harvesting, while they get one-tenth of the grain with chaff or one-eight without chaff for threshing. (Halcrow 1993e, 1998) In the Sheeb area in Eritrea, a typical household accrues 25 to 50% of its average annual income from wage labour. (Halcrow 1997) The large majority of households in Chandia have one or more household members in the civil service with low-ranking jobs, such as messengers and workmen. (Halcrow 1993b)

Wealthier households may also be engaged in business, trade and transport, whereas poorer households in Eritrea, Pakistan and Yemen may also earn an income with the production and sale of handicraft products, such as pottery, mats, baskets and sandals (MOD 1977a, Hadera 2001, Nawaz 2003)

4.4 Migration

Different forms of migration can be found in spate-irrigated areas, which are often an integral and crucial component of the livelihood strategies of many households in order to reduce the inherent risks of spate-irrigated agriculture. One reason for migration is to move livestock to other areas where fodder and water can be found, which may take place annually or only in dry years. In the Sheeb area in Eritrea, a large majority of the population migrate every year to the highlands during the summer months (May to October) in search of fodder and water and to escape the harsh climate in the lowlands during this time of the year. Only the male members of each household remain behind temporarily to divert the floods in July and August and to plant their fields in September. Although this livelihood strategy exploits different agro-ecological zones for acquiring water, food and animal feed, certain activities, such as the emergency repairs of the irrigation structures, are not undertaken at the right time due to shortage of labour. In addition, the annual costs of the seasonal migration, both in cash and labour, are substantial and could be as high as one-forth of the annual income of a typical households. (Hadera 2001; Halcrow 1997; Kahsaye 2002)

Another reason for migration is the search of wage labour by male household members as the incomes generated by spate-irrigated agriculture and livestock keeping are not sufficient to sustain the entire household throughout the year. Most commonly, one or more male members of the household migrate for a number of months to other areas, where they may find work as labourers in the agricultural sector, mines or industry. Normally, these seasonal migrants return to their communities before the start of the flood season or cropping season to assist in the irrigation, preparation and/or planting of the fields. Especially small landowners having land with a low probability of irrigation may have to migrate each year for a number of months to other areas in search of labour, because their small landholdings cannot support their households throughout the entire year. Other landowners only have to migrate in search of labour in dry years as their landholdings produce sufficiently in normal years to sustain their households. In the spate-irrigated areas of Dera Ghazi Khan and Balochistan (Pakistan), seasonal migration is common. In Marufzai, for instance, the most common response to cope with bad years is to seek temporary employment in the coal mines around Duki or become tenants where the water source is more reliable. Poor households in Nal Dat migrate to spate-irrigated areas in Las Bela District, in particular during the harvesting season in December. (Halcrow 1993d-e)

Households having spate-irrigated land may also decide to migrate permanently when they have found permanent employment elsewhere. In Chandia, more than 25% of the landholding households live permanently in a nearby town, where most of them work as civil servants. As the existing spate irrigation system cannot support the entire community, more than half of landholding households in Marufzai have migrated permanently to other spate irrigation systems in the Anambar valley, where they work as casual labourers and in some cases as bonded tenants. (Halcrow 1993b+e)

Migration abroad is reported in spate-irrigated areas in Yemen. In Wadi Rima, much of the labour force is underemployed, if not unemployed, for most of the year as employment is limited to short seasons, principally the main harvest from October to December. As a result, a high proportion of the local population (17% of the adult males) left the country in the 1970s, mostly for Saudi Arabia, where employment opportunities are both expanding and lucrative. In the Shabwah Governorate, 10% to 25% of all extended households have a family member in the Gulf States in 2002. (KIT 2002) In the 1970s, migration from the spate-irrigated area in central Tunisia to Libya was important and many farmers in the Nouael II Project area could install shallow wells with the remittances. (Van Mazijk 1988)

Due to permanent migration, depopulation is a constant and self-reinforcing threat to the farming communities in spate irrigation systems as at a certain moment the number of landowners might be too small to reconstruct the diversion structure and to clean the flood canals in time. As a result, the diversion of sufficient spate water becomes more difficult, causing further depopulation as more landowners decide to migrate. Ultimately, the remaining farmers have to abandon the entire spate irrigation system as the critical mass for maintenance is lost, which occurred in a number of areas in the Las Bela plains in the South of Balochistan. (Van Steenbergen 1997; Ahmad 2000)

4.5 Credit Facilities

Indebtedness is common in spate-irrigated areas as many farmers usually encounter serious cash deficits at certain times of the year and/or they have to make debts to survive an adverse year. Friends and relatives are usually the first source of credit for many small farmers. Shopkeepers and traders are another important source of credit as many small farmers obtain seeds on credit at the start of the cropping season. The interest charged is often very high, which reflects the risks associated with spate irrigation. In Chandia, for instance, farmers took loans for seeds from shopkeepers against a monthly interest rate of 5 to 10%, whereas farmers in Barag purchased seed on credit and paid an 80% mark-up. Farmers may also be obliged to sell their produce at low(er) prices to traders, from whom they borrowed money or products. In Chandia, farming households also buy a pair of bullocks on credit by paying the due sum after the harvest at 25% higher prices. (Halcrow 1993b-c; Hadera 2001)

In the Tihama region in Yemen, the most common form of credit is the traditional system of delayed payment, acceptable to most merchants, traders and shopkeepers. Interest is not officially charged but different price levels may be negotiated depending on the time delay in payment. Traders in expensive capital equipment, such as tractors and pumps, usually offer credit up to 2 years. Shopkeepers and merchants give credit for shorter periods. However, deposits, security and/or a reserve of capital are required for most forms of public and private credit, but this practice precludes poorer farmers from taking advantage of credit for purchase of equipment. (MOD 1977a)

Remittances from abroad could be another source of capital for households in spate-irrigated area. Due to the inherent risks of spate-irrigated agriculture and the cultivation of mainly low value crops, farmers in spate irrigation systems do not have access to formal credit facilities of banks and financial institutions. In Wadi Zabid (Yemen), only large landlords have access to credits with subsidised interest rates from the Agriculture Credit Bank, which they mainly use for the installation of tube-wells for selling ground water to smaller farmers. The latter do not have access to these cheap credit facilities as the bank requires that at least 50% of the investment shall be self-financed by the farmer. (IIP 2002)

4.6 Solidartity and Mutual Assistance Mechanisms

Traditional mechanisms of solidarity and mutual assistance still exist in the spate-irrigated areas to help people in need, struck by a calamity or during important social events (i.e. wedding). However, households facing a crop failure cannot reckon on any form of solidarity or mutual assistance from fellow villagers as it occurs frequently and affect some landowners more than others due to the location of their fields.

Among the Tigre population living in the Sheeb area of Eritrea, groups of five to ten farmers work together on a rotation basis, whereby the farmer for whom the labour is performed provides food. Labour and oxen are also mobilised to cultivate the land belonging to widows and very poor households. Furthermore, mutual self-help groups are spontaneously formed to help each other during field activities or the construction of houses. (Halcrow 1997)

In Balochistan, it is common that labour and means of production are shared to a certain extent. Although tractors gradually take over the role of draught animals, bullocks are still lent to poor villagers for a number of days without charging a rent. Farmers without seeds at the start of the cropping season may ask their fortunate neighbours to help them out. If a farmer cannot access his field or his field bunds have broken during the flood season, others will come to his aid by either irrigating the field on his behalf or assisting in the repair of the field bund. These forms of mutual assistance are more or less an insurance system, because in other years, given the unpredictability of spate irrigation, the current “haves” may be on the receiving end as they have to ask the assistance from those who they have helped this year. (Halcrow 1993a-e, Van Steenbergen 1997)

The most prevalent solidarity mechanism in the rural areas of Balochistan is the Islamic duty (i.e. Zakat) to give part of the agricultural produce and livestock as alms to the needy, whereby preference is given to members of the same family or clan. The payment of Zakat may also be used to finance local religious institutions, such as the mosque or religious school. Zakat is either given in cash or kind and the prescribed amount is one-tenth of the harvest of rainfed and spate-irrigated crops, one-twentieth of the harvest of pump irrigated crops and one-fortieth to one-fifth of the livestock. However, it seems that the actual donations are usually less than the prescribed amounts and that not all landowners pay their Zakat on a regular basis. (Halcrow 1993b-e, 1998)

Another type of assistance is to allow poor persons to pick small amounts of vegetables (i.e. mustard leaves) and melons for home consumption or to collect wheat kernels left on the threshing floor. A less common practice is to give some land in usufruct to a poor relative. Furthermore, it is common that relatives and neighbours offer gifts in cash and kind during special occasions, such as birth, wedding and funeral. For instance, fellow villagers in Chandia arrange food for the first three days of the condolence period for the family facing a death case. These forms of assistance are reciprocal and often within the own social inner circle. (Halcrow 1993b-e, 1998)
