ການກຳໜົດຄວາມໝາຍ ຂອງເຕັກໂນໂລຢີ:

Repair of ancient stone wall bench terraces, and of an associated irrigation and drainage system.

2.2 ການອະທິບາຍ ລາຍລະອຽດ ຂອງເຕັກໂນໂລຢີ

ການພັນລະນາ:

The level bench terrace system in the Colca valley of Peru dates back to 600 years AD. Since then the terraces have been continuously used for crop production, but due to lack of maintenance they have deteriorated, and the population has lost its traditional knowledge of repair.
The rehabilitation of the terraces recreates their original structural design. Broken sections are cleared and the various materials - stones, topsoil, subsoil and weeds - are removed and separated. The foundation is re-established, followed by construction of the stone wall (the ‘riser’). Backfilling with subsoil then takes place; this is consolidated and finally covered with topsoil. Simultaneously the complementary irrigation and drainage systems are reconstructed.
The rehabilitated terraces efficiently conserve soil and water on steep slopes, and they create a favourable microclimate for crops, reducing loss of stored heat at night by minimising air movement (preventing frosts) and mitigating dry conditions through moisture conservation. The main economic benefits are from increased yields and crop diversification.
Terraces are spaced and sized according to slope, eg on a 50% slope, terraces are 4 m wide with a 2 m high riser between terrace beds. Stones of ancient terraces had been widely used to build walls for boundary marking after privatisation of land, therefore a large amount of stone had to be provided by splitting rocks and transporting from other locations.
The area is characterised by steep slopes with loamy-sandy, moderately deep soils (on the terrace beds). Most of the annual precipitation (ca. 350 mm) falls within a period of 3 months, which makes irrigation necessary. The farmers in the area own, on average, 1.2 hectares of arable land, divided into around six plots in different agro-ecological zones. Production is mainly for subsistence. Important supportive technologies include agronomic measures such as improved fallow, early tillage, ridging, and intercropping. Tree and shrub planting at the base of terrace walls is an optional measure with the aim of stabilising the walls, diversifying production and again ensuring a good microclimate. On average
250 trees/ha are planted; these are mainly native species such as c’olle (Buddleia spp.), mutuy (Cassia sp.), molle (Schinus molle: the ‘pepper tree’) and various fruit trees including capulí (Prunus salicifolia).

ຄວາມຄິດເຫັນ:

Major land use problems (compiler’s opinion): - Loss of productive capacity: 30% of the agricultural land lost due to degraded terraces, severe deforestation (through
cutting for fuelwood), overgrazing and burning of grazing areas.
- Inefficient irrigation practices (flooding) due to poor maintenance of irrigation system (and drainage system in poor
condition), flood irrigation leads to deterioration of terraces.
- Loss of traditional knowledge of ancestral crop management practices (abandonment of appropriate rotation practices, lack of residue incorporation/recycling, unsystematic crop layout).

Person days needed for rehabilitation of 1 ha of ancient terrace system depend on degree of deterioration, the
dimensions of the wall, slope angle (the steeper the more terraces) and availability of stones. In the case of the project, under a typical situation, for physical rehabilitation of 1 ha with 6 terraces, each ca 600 m long, 3–4 m wide and 2 m high, with one third of the main structures in disrepair, 18 men and 7 women work for 5 days; shrub planting is extra. Land users bear 35% of the overall costs: they also provide food for the group during work. The programme pays the rest. 450 m3 of additional stones are required to repair the broken parts, the cost includes blasting/splitting rocks and transport to the construction site.
Supportive agronomic measures and agricultural inputs (seeds and manure) are not included. Maintenance costs vary considerably, depending on the specific situation: an average is taken here.

Editors’ comments: Terracing systems on hillsides date back to the beginning of agriculture. Often these feature walls (‘risers’) built of stone, and sometimes they are used for irrigation – as in this case from Peru. While many ancient systems have fallen into disrepair with out-migration of rural populations, this is an example of project-based rehabilitation.
