Land evaluation – towards a revised framework

invest in improved technologies. In areas
with good access to markets, farmers tend to
invest time and effort in new technologies, particularly in conjunction with high-value
products or crops with a well sustained demand. In isolated areas with poor access to
markets there may be little incentive to produce more than required for subsistence.
In such cases, low yields and low productivity may be acceptable to the farmer, and
introducing technologies for increasing fertility
may be perceived as irrelevant, unless
the farmer is failing to meet subsistence needs.
Globalization or the liberalization of the markets for agricultural products should
be an opportunity for the poor, but markets can confer their benefit only to those with
access to them. The poorest are almost excluded by definition, except at the lowest
level of market operation. Opening markets for agricultural
products has concentrated
economic activities and made subsistence farming uneconomic (UNFPA 2002).
Labour
Labour is a major limiting resource for many farmers, so that they will only change
their practices where the alternatives represent a more rational use of their labour time
(Brown and Schreckenberg 1998). Various demographic changes taking place in rural
areas contribute to labour shortages. Men may be migrating to cities in search of wage
labour, or an increasing proportion of children may be going to school;
both trends
reduce the amount of household labour available for farming operations.
The introduction of a technology that increases the workload but produces benefits
only gradually over months or years, such as increasing soil fertility, is unlikely to be
adopted by a small farmer. Farming operations are hard work, often in difficult physical
conditions, and the wisdom of increasing this burden is questionable
unless the benefits
of the extra labour input are immediately evident to the farmer and are realized within
a season. The additional labour required is a major reason why it is hard to introduce
soil conservation methods based on earth structures in areas where they are not
traditionally practised. Labour was also one reason why the agro-forestry technology
of hedgerow intercropping (‘alley cropping’) was rarely adopted by farmers.
