| 内容記述 | This paper aims to explore factors behind the development of small-scale irrigation in Zambia by tracing the experience of irrigation development among small-scale farmers in a village in central Zambia. The paper also seeks to contribute to a deeper understanding of the environmental implications of irrigation development. Irrigation farming in the village studied began as traditional or informal irrigation, whereby vegetables were grown in dambo gardens with the use of bucket irrigation. By the early 1990s, vegetable production in dambo gardens had become an important source of income for many farmers in the village. The combination of rain-fed maize cultivation in upland fields and vegetable growing in dambo gardens provided farmers with relatively secure and diversified income sources. As economic declines and structural adjustment measures in the 1980s and 1990s adversely affected the livelihoods of urban dwellers, farming of the village came to be economically more attractive. Irrigated vegetable production in dambo gardens became more popular as an additional income generating activity after the mid-1990s when the agricultural marketing was liberalized. In the early 2000s, some farmers in the village shifted from bucket irrigation to treadle pump irrigation with the assistance of an NGO. The introduction of treadle pumps entailed new methods in irrigation agronomy such as the use of furrows and pipes, the cultivation of winter maize, and more intensive use of land. The second half of the 2000s is seeing another development in the use of irrigation technology, with some farmers introducing engine pumps and drip irrigation. As irrigation methods developed from bucket irrigation to treadle pump and engine pump irrigation, water consumption level of each farmer likely increased. The typical farming system found in the study area, which comprises the two practices is an expression of farmer adaptations in the face of uncertainties both in rainfall and market conditions. Introduction of new irrigation practices by some farmers can be considered as an expansion of the dambo gardening component of the system. The development interventions by NGOs played an important role in the adoption and diffusion of new irrigation technologies. Support from NGOs related to irrigation development placed greater emphasis on income generation and market sales. The villagers continuously invested in new agricultural management practices and land-care techniques. However, the investments and technology promoted are mainly associated with income-generating activities, which may undermine the capacity of ecosystems to produce services. The case of the village studied demonstrates that responses of the farmers were not necessarily unified, coordinated responses of the “community”. The responses to the new farming practices and NGO support mainly occurred at the level of individual farmers and farmers groups. As irrigation methods shifted to those entailing more capital intensive technology such as engine pumps, farmers’ responses to new opportunities depended increasingly on their resource or capital base including social capital. The shift from bucket irrigation to treadle pump and engine pump irrigation in the area has likely had a substantial impact on the use of water resources, especially groundwater. Since there are no customary or formal regulations on the use of groundwater, current opportunistic use of groundwater for irrigation can result in overuse of groundwater and might cause its decrease and depletion. It is crucial to introduce some mechanism of control and management of water resources which enables the sustainable use of this important resource. |
