2.1 ຄໍາອະທິບາຍສັ້ນຂອງ ເຕັກໂນໂລຢີ

ການກຳໜົດຄວາມໝາຍ ຂອງເຕັກໂນໂລຢີ:

Water retaining polders to reduce flood risk from heavy rainfall or runoff at high tide in coastal lowlands. Alternative production systems will be viable within thesepolders.

2.2 ການອະທິບາຍ ລາຍລະອຽດ ຂອງເຕັກໂນໂລຢີ

ການພັນລະນາ:

In the 19th and 20th century land was reclaimed from the sea to make use of the exposed fertile soils for agriculture through a process known as ‘impoldering’. The reclaimed land is now characterized by intensive grazing and cropland. This is a region where agriculture is the most important form of land use. However, the land needs to be regularly drained. Given the expected increase in precipitation in winter due to climate change, the corresponding increase in freshwater discharge needs to be managed. Furthermore, the periods when natural discharge into the sea oc-curs are likely to decrease – because of rising sea levels also caused by climate change. Consequently, in winter and spring, greater quantities of freshwater will need to be pumped into the sea rather than discharged naturally at the low or ‘ebb’ tide. Specially embanked water retention polders will be required to temporarily impound water as part of a multifunctional approach to coastal zone management.

Purpose of the Technology: These retention polders could be a cost-effective alternative to expensive invest-ments in extra pumping capacities to prevent submergence of low-lying cultivated areas. The primary aim is to restrict floods to the retention polders when the drain-age network is overburdened and cannot deal with the predicted extra demands in the future. The high evapotranspiration from the open waterbody, and the reeds growing within, will also help with reducing the amount of water. During dry sum-mers, the water in the retention polder could also be put to creative use as a source of irrigation. Another potential advantage is that subsurface saltwater intrusion in the region could be prevented by the freshwater-filled polders. During extreme storm surges and in the rare case of breaches in the sea wall, the retention polders would serve as an extra line of defence by holding seawater.

Establishment / maintenance activities and inputs: An embankment enclosing approx. 3,000 ha will be able to store up to 25,000,000 m³ of water. This will improve the drainage of an area of approx. 49,000 ha. The invest-ment for building this water retention area is high – but for the reasons stated it serves a necessary purpose at a cost which is lower than the alternative – increased pumped drainage installations. Maintenance costs will be lower than the drainage alternative as only the integrity of the embankment needs to be monitored regularly. Agricultural land use within the polders is adapted to higher water levels and occa-sional flooding.

Natural / human environment: However within the proposed retention polders – the areas enclosed by the em-bankment - a change from the current intensive grazing for dairy farming and cropland to extensive grazing, open waters and wetlands covered with reeds will take place. The reeds can be harvested for their commercial value as biomass for renewable energy generation, or for other applications (e.g. thatching of roofs or industrial raw material). According to recent investigations, natural reeds growing in brackish water produce as much biomass as maize cultivated for biogas use. In con-trast to maize, no investments in tillage, fertilizer or biocides are necessary for these naturally growing reed stands. Thus the proposed land use provides an economic alternative to the current production system.

ຄວາມຄິດເຫັນ:

Major land use problems (compiler’s opinion): Flood events and droughts may substantially disrupt the current land use system in the future and lead to higher drainage costs and higher economic risks for agricultural production. This will reduce the ecological and economic viability of the current intensive and highly productive land use under a changing climate.

Major land use problems (land users’ perception): There is no awareness of risks due to climate change.

Cut-and-carry/ zero grazing: cows for milk

Improved pasture: cattle for milk and meat

Future (final) land use (after implementation of SLM Technology): Other: Oo: Other: wastelands, deserts, glaciers, swamps, recreation areas, etc

Constraints of infrastructure network (roads, railways, pipe lines, power lines): needs to be adapted to regular flooding

Constraints of recreation (landscape is used for recreation and tourism): change in landscape due to retention area

Constraints of nature conservation area (protected sites): wetter conditions in retention area

4.2 ການແຕ້ມແຜນວາດອະທິບາຍເຕັກນິກ

The figure shows the study region, located on the North Sea coast. The whole area is protected by a sea wall (grey). Crop fields (yellow), grasslands (green) and the drainage system (light blue) char-acterize the region. Large water bodies (blue) sur-rounded by reeds (brown) act as water retention polders. Extensive grazing and reed farming re-places current production systems within the reten-tion polders. The land around the retention area (higher parts of the landscape) profits from the retention areas as the risk of flooding is reduced and can be used for cropland and intensive graz-ing. Depending on the size of the retention polder a huge amount of excess water can be contained. Retention areas of 3,000 ha are able to store up to 25,000,000 m³ water. The height of the dams de-pends on the elevation of the landscape but in general a height of less than 2 m is sufficient.

The establishment costs are for a dam length of 30 km and the enclosed retention area of 3,000 ha. The establishment period will be half a year. The slope in the region determines the costs as the height of the embankments depend on this. Typical heights are from 1 m up to 2 m with a slope of 1:3. . The length of the drainage network for the whole watershed (retention area and the surroundings) is 1,134 km. Maintenance costs of the drainage network are based on long term annual mean cost of 2,270.70 Euro per km including pumping costs. The maintenance cost for the whole retention area will amount to a total of US$ 2,576,200.00.

Prevention of salt water intrusion in the region How can they be sustained / enhanced? Fresh water in the retention polders prevents saline ground water from intrusion. Build polders in areas where saline ground water intrudes.
Endangered species might obtain new habitats in the retention area How can they be sustained / enhanced? Extensive land use can help to optimize the habitats for endangered species and increase attractiveness for tourism.
Through investments in building retention areas the very expensive strengthening of the existing drainage system is not necessary anymore How can they be sustained / enhanced? By increasing the attractivity for touristic use in the retention area benefits for land owner can be generated and the probability to build up retention areas instead of strengthening the existing drainage system is increased.

Retention polders in an important tourism region will change the landscape and this may reduce the value of the region for tourism.	Include tourism concerns in the retention area (access, infor-mation, attractiveness).
Loss of land for agricultural production (highly productive arable land)	Establish retention area in low elevated parts, where there is not a high interest for agricultural production.
Endangered species might lose habitats when building up the retention area	Do not build a retention area where endangered species live.
Loss of livelihoods	Retention areas should be planned for parts of the landscape without settlements.

High water levels (especially with changing water levels) may generate high emission of greenhouse gas	Ground water levels should kept stable near to the soil surface.
