2.1 ពណ៌នាសង្ខេបខ្លីពីវិធីសាស្ត្រផ្សព្វផ្សាយ

Highly organised campaign to assist land users in creating terraces: support and planning from national down to local level.

2.2 ពណ៌នាលម្អិតពិវិធីសាស្ត្រផ្សព្វផ្សាយ

ពណ៌នាលម្អិតពិវិធីសាស្ត្រផ្សព្វផ្សាយ:

Before 1964, the slopes on China's Loess Plateau were cultivated up and down by machinery. Consequently soil and water were lost at high rates, and fertility and yields declined. Accessibility to cultivated land became more and more difficult due to dissection by gullies. The first terraces were established by self-mobilisation of the local land users. However there was no standard design. Furthermore, as the individual plots were very small and scattered all over the village land, terracing needed better coordination. Between 1964 and 1978, the local government at the county level took the initiative of organising farmers and planning terrace implementation according to specific technical design on a larger scale. At that time the land was still communally managed by production brigades. Through mass mobilisation campaigns people from several villages were organised to collectively terrace the land - village by village - covering around 2,000 hectares each year. Labour was unpaid.The Yellow River Conservancy Commission (YRCC) came into being in 1948 - and the Upper and Middle Yellow River Bureau in 1977. This gave greater impetus to the implementation of SWC in the Loess Plateau. After 1978, land use rights were allocated to individuals (though official ownership was still vested in the state). SWC specialists and county level SWC bureaus started to work with groups of farmers who had land use rights within a given area. Survey and design were carried out. The farmers organised themselves, consolidated the parcels of land, and then after the conservation work was done they redistributed the terraced fields.
In the 1980s the government started to financially support land users involved in SWC projects. Subsidies ranged from (approx.) US$* 20/ha in projects at county level, to US$* 55/ha for national projects (eg through the Yellow River Commission), and up to US$* 935/ha when World Bank projects were involved - as in the recent past. Implements were provided by the farmers themselves. Then, in 1988 a nationwide project in SWC - which originally was proposed at county level - was approved by the national government. Furthermore, in 1991 a national law on SWC came into force. Protection of the Yellow River and associated dams became a priority at regional and national levels. In total, within Zhuanglang County, 60 SWC specialists/extensionists cover an area of 1,550 km2, and most of the terraces were built with low levels of subsidies. Annual plans about implementation of new SWC measures were made during summer. Small areas were planned at village or township level, whereas bigger areas (> 7 hectares) were designed at county level. Implementation then took place during winter. Terracing was implemented first where access was easiest and closest to settlements, and only later, further away. * exchange rate: 1 US$ = 8 Chinese Yuan (May 2006).

  • ផ្អែកលើគម្រោង/កម្មវិធី

2.8 គោលបំណង/ទិសដៅសំខាន់នៃវិធីសាស្ត្រផ្សព្វផ្សាយ

Aims of the approach are: - water conservation (this is a semi-arid area), - soil conservation: reduce soil loss on the sloping and erosion-prone land of loess plateau, - enhancing soil fertility, and consequently production, - improve people's living conditions, These primary objectives were to be achieved by building level bench terraces on a large scale through a structured and organised campaign. Finally at the national level, a fourth aim was added: the protection of the Yellow river (avoiding floods and reducing the sediment load)
The SLM Approach addressed the following problems: - lack of organisation, capital and technical knowledge in farmer communities to counter the underlying problems of water loss, soil loss, fertility decline and downstream effects on the Yellow River (floods and sediment) at catchment level, - absence or poor maintenance of erosion control measures

ភាពអាចរកបាននៃធនធានហិរញ្ញវត្ថុ និងសេវាកម្ម
  • រារាំង

Initially farmers were not paid and as they had no immediate benefit from, or security over, the use of the land. The investment in construction was a heavy burden on poor farmers.
Treatment through the SLM Approach: After 1988, labour inputs by farmers started to be partly covered by subsidies provided by local and national government

  • រារាំង

Land users leased the land from the state and land users??? rights were insecure in the long term. Investments in SWC were not encouraged.
Treatment through the SLM Approach: National government persuaded land users to implement terraces by 'selling' the benefits (increased yield and easier workability of the land). After 1978, individual user rights motivated farmers to invest in SWC.
The existing land ownership, land use rights / water rights hindered a little the approach implementation Ownership of land and its resources belongs to state and communities: land users only lease the land for a period of time. Due to uncertainty over future user rights and possible reallocation in response to changes in population and household needs, additional investments into measures may be hindered. 1978 a first major change took place by allocating some individual land use rights.

Poor knowledge of how to reduce water loss, soil loss and fertility loss. Technical solutions were needed at the catchment level, involving the whole population.

មតិយោបល់:

bio-physical aspects were regular monitored through measurements; indicators: runoff loss, sediment load, soil moisture
technical aspects were regular monitored through measurements; indicators: structure of terraced areas, slope of risers, levelness of terrace surface
socio-cultural aspects were ad hoc monitored through observations; indicators: land users' perceptions of terraces
economic / production aspects were regular monitored through measurements; indicators: yield, income of land users
area treated aspects were regular monitored through measurements; indicators: terraced area
land users involved aspects were ad hoc monitored through measurements; indicators: number of farmers directly involved in terracing and farmers benefited directly
management of Approach aspects were ad hoc monitored through observations; indicators: number of small watersheds terraced

As the Zhuanglang area was one of the pioneering areas for the Loess Plateau other regions were able to profit from the approach. But likewise, experiences gained in other counties helped improve the approach, and a basically similar approach has been applied over the whole Loess Plateau - though the level of subsidies for construction is much higher under World Bank projects.

  • មិនប្រាកដ
ប្រសិន ទេ ឬមិនប្រាកដសូមបញ្ជាក់ និងពន្យល់:

Given the recent escalation in payments made to land users for implementation under certain projects it seems that the costs will be too high to sustain. Currently the Ministry of Finance is demanding that in-depth cost-benefit analyses are carried out involving environmental, social as well as economic assessments.

6.4 ភាពខ្លាំង/ គុណសម្បត្តិនៃវិធីសាស្ត្រផ្សព្វផ្សាយ

ភាពខ្លាំង/ គុណសម្បត្តិ/ ឱកាស​ ទស្សនៈរបស់បុគ្គលសំខាន់ៗ
Farmers are getting direct benefits: marked increase in productivity, improved workability of the land, etc.
The collective activities/organisation strengthens the community and enhances social stability and coherence within villages; collective activities are expanded to other sectors, such as road construction, supply of agrochemical inputs, etc.
Heavy investment made by the land users and local as well as national government to reduce land degradation.
Many people involved and trained at different levels (pyramid system; see training/extension); commitment by all stakeholders.
Efficient organisation, planning to cover a large area, which is very susceptible to land degradation.

6.5 ភាពខ្សោយ/ គុណវិបត្តិនៃវិធីសាស្ត្រ និងរកដំណោះស្រាយ

ភាពខ្សោយ/ គុណវិបត្តិ/ ហានិភ័យក្នុងទស្សនៈរបស់បុគ្គលសំខាន់ៗ តើបច្ចេកទេសទាំងនោះបានដោះស្រាយបញ្ហាដូចម្តេច?
High costs: farmers depend on external support from the government, they are not willing to invest their labour without payments (as it used to be in communist times) New approach: give farmers loans for construction as now they use machines to do the work. In addition, search for cheaper SWC technologies and for improving the benefits.
The steeper slopes which are also further away from the village, are now often not cultivated and maintained as they are too far and marginal in production Solutions need to be found for these areas, eg afforestation.
