Impact of treadle pump irrigation technology on smallholder poverty and food security in Malawi: a case study of Blantyre and Mchinji districts

The Malawi Government has intensified the use of treadle pump irrigation technology in an attempt to increase agricultural production and also to enrich the livelihoods of resource-poor farmers. As a result, the treadle pump is gaining in popularity among smallholder farmers throughout the country. This study was conducted in the districts of Blantyre in the Southern Region and Mchinji in the Central Region of Malawi. A total of 50 treadle pump and 50 non-treadle pump farmers were interviewed in each district to assess the impact of treadle pump irrigation technology with regard to food security and poverty. Gross margin analysis showed that adopters of the technology had higher net farm incomes per hectare (NFIs/ha) than non-adopters per year. In Blantyre, NFI/ha value for adopters was MK122, 855 (US1007) compared with MK15, 987 (US131) for non-adopters under irrigation conditions. Similar results were found in Mchinji with MK51, 858 (US425) and MK16, 090 (US132) for adopters and non-adopters, respectively. Likewise, under rain-fed conditions, adopters had higher NFIs/ha than non-adopters: in Blantyre, the respective NFIs were MK19, 497 (US152) and MK3344 (US27), whereas in Mchinji the respective values were MK16, 896 (US138) and MK10, 084 (US83). Furthermore, the well-being measurements and analyses of poverty revealed a higher poverty level among non-adopters compared with adopters. The former also had a greater relative risk of falling into deeper poverty than the latter. Transition matrices depicting movement in and out of poverty showed that from 2004 to 2005, some poor adopters moved out of poverty while some non-adopters dropped from being non-poor to poor. No adopter moved from non-poor to poor. From the results, it is concluded that the Government of Malawi should be urged to increase the availability of this kind of technology to the market at a reduced cost by offering tax incentives to local manufacturers and by using an input voucher system to subsidize qualified poor smallholder farmers.
