ການກຳໜົດຄວາມໝາຍ ຂອງເຕັກໂນໂລຢີ:

The technology combines the integration of native tree species into rubber monocultures with changed weed management to mitigate negative environmental impacts and to provide alternative income options for farmers.

2.2 ການອະທິບາຍ ລາຍລະອຽດ ຂອງເຕັກໂນໂລຢີ

ການພັນລະນາ:

Natural rubber is a crucial renewable resource produced from the tree Hevea brasiliensis. Production is largely based on monoculture, often associated with chemical-based clean-weeding. This causes environmental problems such as loss of biodiversity, pesticide pollution and erosion of topsoil. The SLM-technology aims at mitigating negative impacts by interplanting the rubber with native tree species which have economic potential of their own. Changes in weed management are part of the package also.

Native (indigenous) tree species are integrated into mature rubber plantations. Criteria for species selection are: a) adapted to environmental conditions; b) shade tolerant; c) vertical growth not affected by light; d) conservation value; e) economic potential; f) easy to manage. Rubber trees are usually planted in rows at a spacing of 6-8 m, and an intra-row distance of 2.5 to 3 m. The native trees are planted between the rubber rows. The plantation should be mature as the canopy will have reached its highest density, and weed competition is naturally suppressed. The spacing of the native trees needs to be adapted to their growth potential and intended usage. After planting, regular monitoring is necessary to identify pests or diseases. The following species were selected for demonstration sites: 1) Parashorea chinensis, a valuable timber tree, 2) Taxus mairei, a multi-purpose tree, providing good timber but also an anti-cancer drug, taxol, and 3) Nyssa yunnanensis, selected for its conservation value. At the end of the economic life span of the rubber trees (about 30 years) there will be several options, but there are three main ones. First the rubber plantation can be replanted, although the harvest of the Parashorea chinensis trees would be premature. The Taxus mairei trees could be maintained through a new plantation cycle. Second, both, the rubber and the intercropped trees could be maintained for future timber and taxol production. Third, the plantation could be transformed into a sustainable forest managed scheme where the rubber trees are extracted step by step and the intercropped trees maintained for their intrinsic value.

Procedures for the selection and planting of the indigenous tree species are crucial. Identification should be based on suitability for the climate and soil as well as economic potential. The raising of tree seedlings requires experience and nursery propagation by experts might be required. Only healthy seedlings should be used. Planting should take place during rainy periods. Potted seedlings are better than bare-rooted seedlings since they establish better. Generally, weed management (if necessary) should shift from herbicide application to mechanical weeding. Grass competition needs to be avoided in any case! Controlled cover of natural undergrowth will reduce erosion and promote water infiltration.

The implementation site for the trials is located in Xishuangbanna Prefecture, Yunnan Province, SW China. The original vegetation was tropical rain and monsoon forest, but now there is a rich mosaic of different land-use and vegetation types. The whole region is exceptionally species rich and part of the Indo-Burma-Biodiversity Hotspot.

3.2 ປະເພດການນໍາໃຊ້ທີ່ດິນ ໃນປະຈຸບັນ() ທີ່ເຕັກໂນໂລຢີ ໄດ້ຖືກນໍາໃຊ້

ຄວາມຄິດເຫັນ:

Major land use problems (compiler’s opinion): Large-scale expansion of rubber monocultures results in the loss of topsoil and siltation of streams with respective consequences for CO2 emissions (increased), soil degradation, water quality and stream ecology. The excessive application of agrochemicals adds to these problems. The monoculture practice combined with clean weeding results in plant biodiversity loss. The related simplification of habitat structures also leads to a considerable decline in animal biodiversity.

Major land use problems (land users’ perception): The focus of land users is primarily on sustainable income, and their environmental concerns mainly relate to water provisioning (land user's point of view). In the farmers view: “The biggest environmental problem is water quantity. Rubber sucks out a lot of water, therefore we do have a water scarcity problem”. Farmers are aware of the contamination of drinking water due to the use of pesticides and herbicides in the rubber plantations.

Future (final) land use (after implementation of SLM Technology): Mixed: Mf: Agroforestry

Type of cropping system and major crops comments: The majority of farmers shifted to pure rubber growing, although many villages still have paddy rice fields.

ຄວາມຄິດເຫັນ:

Main causes of degradation: deforestation / removal of natural vegetation (incl. forest fires) (Replacement of forests by monocultures.), poverty / wealth (Older people still have the memory of extreme poverty. Rubber was the main driver to reduce poverty; high profit gained by rubber encouraged people in pursuit of large scale monoculture.), inputs and infrastructure: (roads, markets, distribution of water points, other, …) (A tremendously improved infrastructure allows the establishment of plantations even in previously remote areas.), governance / institutional (Strong support from government in terms of subsidy and other incentives from 1980s to 2000s; subsidies are more recently reduced)
Secondary causes of degradation: crop management (annual, perennial, tree/shrub) (Clear-weeding, mainly with herbicides.), disturbance of water cycle (infiltration / runoff) (Removal of natural vegetation leads to higher runoff), land tenure (Introduction of Household Responsibility System in 1980s gave use-right to farmers. This pushed decisions on transformating natural forests to monocultures. No full property rights could hinder could), labour availability (Compared to the traditional agricultural system, rubber monocultures require less labour. Recently, there is even less labour available due to the relatively low income gained by rubber), education, access to knowledge and support services (The awareness about ecosystem services and functions is still poorly developed.), war and conflicts (Chinese government´s objective to be independent on important strategic resources such as rubber)

4.2 ການແຕ້ມແຜນວາດອະທິບາຍເຕັກນິກ

The concept is based on the commonly suggested planting scheme of rubber with a row distance of ca. 7 m and a spacing of trees within the rows of ca. 2.5 to 3 m, resulting in ca. 450 to 500 trees/ha. The intercropping will take place between the rubber rows, on terraced slopes between the rubber terraces. Planting takes place after the plantations have reached half of their economic life span, which is ca. 15 years. It is important to consider that farmers often plant much denser than suggested by official guidelines, which needs an assessment of the light / shade conditions. With a too high rubber density the resulting light conditions might be too poor for intercropping even for forest trees. In our case the distance within a row of the intercropped trees has been set at 6 m, due to the (known) ecological characteristics of the selected 4 tree species. But the decision needs to be taken specifically for each new site, the potential tree species and the intentions of the land-user. Thus, in our case, we opted for a higher density of Taxus (bold circles) which is well known for its slow growth. and integrated the two other tree species at a wider distance (dotted circles).

Seedling costs are by far the major cost factor. Since the selected species are very unusual and don't have a considerable market they were extremely expensive. Since Taxus is also a reputed medicinal plant, it might also have influenced the price. All other costs are actually negligible compared to the costs of the seedlings. In this case the establishment of an own nursery might considerably reduce the costs, since propagation at least of Taxus and Parashorea is easy if the seeds can be acquired.

The technology is based on a long-term perspective and thus favours farmers who have a such an outlook. But farmers with little land usually think short-term.	The current trend of rural-urban migration will support the technology since it can be easily combined with off-farm work. According to SURUMER findings off-farm income already contributes about one third of the overall household income in the rubber growing areas.
Current establishment costs are very high due to the lack of a seedling market.	If the technology becomes known and popular, more nurseries will produce seedlings which will reduce costs. Alternatively, farmers might establish their individual (or community) nurseries.
The technology requires considerable knowledge about tree ecology and tree breeding.	There should be extension officers at the local agricultural or forestry bureaus supporting farmers.
