The agricultural system in Sub-Saharan Africa is a predominantly small-scale farming system with more than 50% of the agricultural activity performed by women, producing about 60-70% of the food in this region.Gawaya 2008 While women provide the majority of the labor in agricultural production, their access and control over productive resources is greatly constrained due to inequalities constructed by patriarchal norms.Doss 1999

Women’s role in agriculture

Women play a critical role in food security in this region of Africa by fulfilling their role as food providers. They make essential contributions to the agricultural and rural economies in all developing countries. There are 3 basic variants of household food production systems in Sub-Saharan Africa:

Women are responsible for the production of all or most food crops. In this variant, food plots are considered women's plots. Men and women jointly cultivate staple food crops in fields controlled by male household heads. In this type, the male household head controls the output. Men produce food, while women transform the agricultural products into food. This variant is mainly encountered where Islamic practices of female seclusion prevent women from engaging in fieldwork.Koopman 1992

In many countries in Africa, there is a rigid division of labor by gender in agriculture. This division may be based on types of activities performed on the farm or types of crops grown by men and women. The division of labor is based on patriarchal norms that typically require women to care for the needs of the members of the household and men to bring money. Women are also expected to help their fathers and later on their husbands in the fields, which increases women's workload. Sometimes men help women in clearing their plots to prepare the land.Mehra and Rojas 2008

In regions where women and men work on separate plots growing different crops, women are usually engaged in subsistence farming to provide food to fulfill the needs of the members of the household, while men are engaged in the production of a different subsistence crop and/or cash or export crops. Since the early 21st century, this pattern has been prevalent in several Sub-Saharan African countries like Tanzania, Uganda, Cameroon, Burkina Faso, etc. This distinction can be explained as a result of gender norms that assign women with the responsibility of feeding the family and men with the responsibility of providing cash income.Pitcher 1996

In Southeast Nigeria, for example, there exist distinctions between traditionally "male" and "female" crops. "Female" crops are normally ephemeral or short-lived household crops, including cassava, beans, maize, plantains, and cocoyams. "Male" crops, meanwhile, include food staples such as yams, which are also considered the "prestige" crop.

Rural women often manage complex households and pursue multiple livelihood strategies, Although women mainly grow food crops for household consumption, if there is any marketable surplus, they sell it in the market. However, women's primary responsibility is to feed the family and only after that they can engage in other income earning activities. The distinction between crops is sometimes not very clear especially in the case of maize which is a staple crop in several Sub-Saharan African countries as well as a cash crop. With the introduction of high yielding varieties of maize, now the distinction is that the high yielding varieties tend to be men's crop, and local varieties are women's crop. This pattern has been observed in Malawi where local varieties of maize are woman's crop while hybrid varieties are cash crops cultivated by men.Galdwin 1992 The logic is the same: high yielding varieties provide large amount of marketable surplus which allows men to provide cash income while women continue with varieties that provide enough for subsistence consumption.

Women's role is not limited to food production; they are also required to process and prepare the food they grow, perform care work in the household and also help men in their cash crop production.

As for division of labor by tasks, traditionally, men cleared the forests, burned the bush, tended and harvested the fruits of tree crops such as the oil palm, fenced fields against wild animals, and in some regions planted crops. Women are responsible for weeding, post-harvest production, and food preparation. Women are also responsible for transporting and marketing the cash crops with male members of the household. In a study for Kenya in the 1980s, it was reported that women were mainly responsible for hand digging, harvesting and transporting the crops while men were responsible for building the granary.Pala 1983 However, gradually the distinction between men's and women's tasks is becoming quite blurred. There are very few tasks that are done exclusively by men like clearing of field. Women perform most of the tasks on their plots from sowing, weeding to harvesting, and may get some assistance from men in clearing and preparing the land for cultivation. On a man's plot, women may provide help in weeding, harvesting, etc.

There is also some evidence that the roles of men in subsistence agriculture were traditionally somewhat greater in many regions before the period following the introduction of additional New World crops from the Americas such as plantains, maize, and cassava. In contrast to certain older traditional and indigenous staple food crops like yams or millet which tended to, and continued to be, grown mainly by men or with more male involvement (sometimes grown along with, varying by region, supplementary food crops often grown with more female involvement such as cocoyams or sometimes rice), New World crops were often grown with more female involvement. The introduction of cash crops as well as of wage labor during the colonial period (also incentivized partly by colonial-era taxes in cash), and the formation of a more cash-based economy, also tended to further lessen the participation of men in subsistence farming, as they increasingly participated in those newer more lucrative occupations in order to acquire and provide cash for their families at home. Men's traditional involvement in subsistence farming in pre-colonial times tended to be somewhat greater in West Africa than in Central and much of East Africa.Goody, Jack.

Changing roles

The gender roles and responsibilities in subsistence economies of Sub-Saharan Africa are dynamic and change with new economic situations. One of the important change noted in the first decade of 21st century is increased participation of women in agriculture as men migrate to work outside of agriculture. For example, in Kenya, Jolou women in the 1980s performed more tasks that were originally considered ‘male’ tasks. Also when men move to non-farm activities, women become more involved in cash cropping. As a result, the gender division of labor by crop and tasks becomes less rigid.Saito 1994

The change in roles is more uni-directional as when economic situation changes it does not appear that men are taking over household activities or production of subsistence crops. Men will increase their participation in women's activities only if some profitable economic opportunity arises. In Burkina Faso, men are becoming involved in picking of Shea nuts which was traditionally women's activity as in the 1980s the sale of these nuts has become highly profitable.Zuidberg 1994

Female-headed households The proportion of female-headed households surged significantly since the 1990s. However, the majority of those are de facto headed households and arise because male heads migrate in search of other income-earning opportunities. The proportion of female-headed households varies from 12.9 percent in Niger to 39.3 percent in Namibia between 1998 and 2003.Maffioli, Gabrielli and Sacco 2007 The female-headed households tend to be more heterogeneous. On an average, they tend to be small in size, have lower incomes and be less likely to adopt technology.

Household headship plays an important role in agricultural productivity. To the extent female-headed households are smaller, it may be that they are less productive than male-headed households due to shortage of labor especially in peak seasons.Larson and Kanyangwa 1990 The causality may be reversed as well. If the household is poor and has low incomes, the male head will migrate to find other opportunities. Further, as these households have lower incomes, their ability to adopt technology is also restricted. A study in Zambia finds a negative relationship between female headship and fertilizer adoption.Jha and Hojati 1993

Access to land

The land tenure systems in Africa vary across the continent. Both women's access to land and security of women's land tenure affects overall productivity. Traditionally, land may be allocated through lineage or village heads which is a model which still persists despite increasing private or state ownership of land. In patrilineal lineages women have access to land through male relatives. For example, in the Beti of Southern Cameroon, women cannot inherit land. They are granted food plots by their husbands but they are not allowed to plant cash crops.Koopman Henn 1983 When allocations are made by village heads, a lot depends on their perception of different individuals' need for land. To the extent that women are perceived to be less capable of farming their allocations are smaller.

Overall, women's access to land in African societies is quite restricted, even in cases where the law protects women's rights to land, traditional customs inhibit their access and control over land. An example from Mozambique points out that customary law protects single-women and widowed women in access to land. However, there are customs that constrain women's access to land. Single-women can gain access to land through their fathers, brothers or uncles. But, upon marriage in patriarchal communities women's access to land held by these relatives is lost, as they are expected to have access to land through their husbands. Generally, women tend to have smaller land holdings and less fertile plots.

Finally, control over land is an important factor which explains the large differences in investments on land made by men and women. A woman who may have obtained land through her husband may be hesitant to invest in technology if she perceives her marriage to be unstable. In Zambia, if a marriage is dissolved the land reverts to the lineage and woman has only a limited claim on the land.Milimo 1991 Among the Haya of Tanzania, women farm grassland plots but do not have permanent rights to the land.

Technological development

According to the agricultural intensification hypothesis, as the population pressure increases and agricultural production moves away from a more traditional practice to a more tool based or mechanized (use of plough) farming, role of women in agriculture declines. However, this decline in women's role is more in relative terms than in absolute terms.Boserup 1970 With increased capital intensification like increased use of tractors and ox implements, acreage increases and that implies women have to do more weeding and harvesting and increased work of caring for domestic animals, thus, more labor demands from women.Galdwin and McMillan 1989
