2.1 ຄໍາອະທິບາຍສັ້ນຂອງ ເຕັກໂນໂລຢີ

ການກຳໜົດຄວາມໝາຍ ຂອງເຕັກໂນໂລຢີ:

A Terrace is a structural SLM practice with a raised flat platform built on the slope to reduce soil loss and runoff on the slope, increase the rainfall infiltration and yield.

2.2 ການອະທິບາຍ ລາຍລະອຽດ ຂອງເຕັກໂນໂລຢີ

ການພັນລະນາ:

A terrace is a leveled section of a hilly cultivated area, designed as a method of soil conservation to slow or prevent the rapid surface runoff and erosion of topsoil. Often such land is formed into multiple terraces, giving a stepped appearance.

Purpose of the Technology: To change the landform for better agricultural condition of operation of tillage and harvasting, reduction of soil erosion and water loss and finally for higher production.

Establishment / maintenance activities and inputs: The building of a terrace in the loess plateau takes long because loess is very soft and deep and the severe soil erosion and shortage of water in agriculture hinders the process, as well. Previously, terraces were constructed by hand. These terraces weres narrow and damaged by the great storms. Now, the machinery is used to build wide terrace with high bank size in the loess plateau. The establishment of terrace needs a lot of money but it is a long-term investment. The maintenance of terrace is considerable economic because the major efforts are the annually improvment of terrace bunds.

Natural / human environment: The soil erosion is very severe because of the cohesionless loess soil and very intensive rainfall storms in the summer and autumn that would destroy the land surface into broken hilly area. Terrace is a kind of measure to resolve it combining with crops. The human activities here is very intensive because they must plant on the slopes that would make the soil erosion greater.

ຄວາມຄິດເຫັນ:

Main cash crops: Beans, sunflower, apple, Chinese date, alfalfa
Main food crops: Potato, millets, maize, buckwheat
other crops: vegetable

Major land use problems (compiler’s opinion): Soil and water losses are alarming in this region. The loose loess, steep slopes, and intensive storms in the summer and autumn, accelerates this process. Aditionally, the lack of rainfall negatively impacts agriculture and vegatation. Sediment deposition could increase the river bed and diminish capacity of reservoirs. On one hand side floods occur frequently because of fast and large runoff and on other hand side sedimentation in rivers reduce their water carring capacity.

Major land use problems (land users’ perception): The low yield of crops and the low income from land is more important for the local people. It is necessary to improve the agricultural conditions. The land, especially the tableland and gentle slope land could be convert into terrace.

Future (final) land use (after implementation of SLM Technology): Cropland: Ca: Annual cropping

Type of cropping system and major crops comments: The composation of agriculture is very simple here.

Livestock is grazing on crop residues

ຈຸດແຂງ / ຂໍ້ດີ / ໂອກາດໃນການນໍາໃຊ້ທີ່ດິນ
Increase yield and income. How can they be sustained / enhanced? If the terrace is maintained well, the water condition would be better than that on the slope land even in dry year with low precipitation.
Convenient to till and harvest How can they be sustained / enhanced? Tillage and harvesting is much easier on the plain flat land than on the slope. The maintainance of terrace is important.

ຈຸດແຂງ / ຈຸດດີ / ໂອກາດ ຈາກທັດສະນະຂອງຜູ້ປ້ອນຂໍ້ມູນ ຫຼື ບຸກຄົນສຳຄັນ
Reduce soil erosion on the slope. How can they be sustained / enhanced? The loess soil is prone to erosion because of its loose character induced by fine sand content and low soil organic matter. The plain flat makes the dispersion and transportation of soil particls difficult.
Reduce runoff and increase the soil moisture How can they be sustained / enhanced? The runoff generation is smaller on the plain than on the slope. Slow movement of surface water lead to more soil infiltration.
Increase yield. How can they be sustained / enhanced? Water is the limit factor in the loess plateau. The yield would increase if there is enough water available.
Decrease flood risk. How can they be sustained / enhanced? It is a kind of off-site benefits because less runoff generation and gentle process of runoff decrease flooding. Reduction of sediment also diminish flood risk because the drainage capacity of channel and adjusting capacity of reservior increase when sedimentation decrease.
