Impacts of the technology: This in<strong>for</strong>mation is asked of the specialist under questions<br />

QT 3.1.2 – QT 3.1.5. Categories are then ranked (+=little, ++=medium, +++=high), listed<br />

according to rank and additional comments/specifications given in brackets where available<br />

e.g. crop yield increase (maize +200%; beans +150%).<br />

Assessment<br />

Impacts of the Technology<br />

Production and socio-economic benefits Production and socio-economic disadvantages<br />

increased crop yield<br />

increased farm income<br />

decreased workload<br />

Acceptance / Adoption<br />

The in<strong>for</strong>mation below relates to the spread of the technology.<br />

improved conservation / erosion knowledge<br />

Within the area covered by the case study (the ‘technology area’:<br />

see box on page one) we are considering only those people who<br />

have applied the technology reduced soil (though loss often this means all/ nearly<br />

reduced surface runoff<br />

all the households). The infomation below refers to how the spread<br />

of incentives. The following increased details soil moisture are given:<br />

reduced emission of carbon and greenhouse gases<br />

- % land users / number of families who accepted the technology<br />

without incentives (spontaneous adoption); from QT 3.3.2.1<br />

Off-site benefits Off-site disadvantages<br />

Farm income may increase with up to12%. There is no known effect on education, health etc. The subsidies applied <strong>for</strong> cereal<br />

production in a rotation system of fallow & <strong>for</strong> contour ploughing contribute to improved livelihood of most farmers.<br />

Benefits/costs according to land user<br />

<strong>for</strong> establishment: QT 3.2.1<br />

Benefits compared with costs short-term: long-term:<br />

Establishment slightly negative slightly positive<br />

Maintenance/recurrent slightly positive slightly positive<br />

When a disc-plough was not already used in normal farming operations, this implies a slightly negative influence on farm income during<br />

establishment.<br />

Acceptance/adoption:<br />

There are no subsidies <strong>for</strong> reduced tillage. Nevertheless, 100% of land user families have implemented the technology with external<br />

material support since there are subsidies <strong>for</strong> parts of the technology such as contour ploughing and rotational farming allowing a fallow<br />

period (1-2 years) after harvest. Practically 100 % of farmers use these subsidies; still reduced tillage is implemented 100% voluntary.<br />

There is a little trend towards spontaneous adoption of the technology. There seems to be a growing public awareness of the fact that<br />

frequent deep rotational ploughing is not always necessary and results in higher production costs.<br />

Benefits/costs according land user<br />

Short-term / long-term categories: the land<br />

users’ view of how beneficial the technology<br />

is with respect to establishment and to maintenance<br />

activities, and in the short- term and<br />

the longterm <strong>for</strong> each. Note: this is essentially<br />

a qualitative question, having seven possible<br />

answers ranging from ‘very negative’ through<br />

‘neutral/ balanced’ to ‘very positive’. Another<br />

consideration is that when incentives are used<br />

<strong>for</strong> establishment, land users may view the<br />

benefits <strong>for</strong> establishment as ‘positive’ relating<br />

the benefits to the incentives rather than the<br />

impact of the SWC technology.<br />
