Abstract
This study assessed agro-pastoralists’ adoption of soil and water conservation measures in Aba’alla. A convergent parallel mixed design was used, combining quantitative and qualitative methods. Samples were taken from five selected kebelles of spate irrigation areas in the Woreda. Questionnaires, group discussions, interviews and field observations were used. About 150 households were taken from 2450 households using simple random sampling techniques for administration of the questionnaires. To examine perception of the agro-pastoralists, a five-point Likert rating scale was employed. Moreover, bi-variate and multi-variate statistical analyses were applied. The results showed that adoption of soil and water conservation technologies of agro-pastoralists is significantly and positively correlated with their perception level on soil erosion (r=.308, p<0.01) and its effect (r=.182, p<0.05). Their perception, related with household head’s perception on soil erosion, is positively and significantly correlated with his/her educational status and other factors. The results showed that 35.3, 28.7, 17.3 and 8.7% of sample households are respectively: very low adoption, low adoption, moderate adoption, high adoption; and the remainder are non-adopters. They reported using structural like gabions and bunds and sometimes agronomic methods. Only a few farmers used biological soil conservation methods. Among these methods, soil management methods contour farming and minimum tillage are relatively in wider usage. Factors negatively affecting the farmers’ adoption of SWC included gender, age, marital status, number of children, size of farm, credit and land ownership. However, educational attainment of household, off-farm activity, extension, participation on mass SWC campaign, perceived erosion occurrence, livestock wealth and farming experience are positively affecting it. From these factors, statistically significant ones are educational status (at p<0.01), access to extension (at p<0.01) and credit (at p<0.05), off-farm activity (at p<0.05), and land tenancy (at p<0.05), those factors significantly affecting the adoption extent and behavior of agro-pastoral community of the study area. Key words: Adoption of conservation practices, conservation failures and preferences, demographic factors, flooding, soil and water conservation (SWC) measures.
Highlights
Land degradation has caused a series of environmental problems for a long period of time throughout the world, because it damages and reduces soil fertility
The interview showed us, most of the females who are household heads manage their land through share cropping or renting to families with male household heads and contract with other men from Tigray highland to plough
About 46.26% of the population was in the 36 to 50 age level, and was followed by 36.73% of household heads in the 18 to 35 age level. This indicates that a large number of household heads are in the medium and younger age groups
Summary
Land degradation has caused a series of environmental problems for a long period of time throughout the world, because it damages and reduces soil fertility. It has been the causes for soil fertility reduction, food insecurity, depletion of productive resource, influenced individual production capacity, and led to agricultural land. Land degradation is one of the basic problems the farmers have been facing, which hindered agricultural production and caused food insecurity in Ethiopia (Mengstie, 2009). As Woldeamlak and Sterk (2003) and Bobe (2004), investigated in Ethiopia: about 27 million ha are significantly eroded; 14 million ha are seriously eroded and 2 million ha reached the point of no return with an estimated total loss of about 2 billion meter cube soil per year
