这里所描述的技术在土地退化方面是否存在问题,导致无法被认为是一种可持续的土地管理技术?:

注释:

Through this technology, farmers can pump water from shallow wells for agriculture throughout the year: it can lower the groundwater table and reduce salinity. This technology has resulted in reduction salinity in surrounding low land areas. Hence, shallow wells have been accepted by land users.

2. SLM技术的说明

2.1 技术简介

技术定义:

Pumping groundwater from shallow wells for agriculture can control the groundwater table in recharge areas. It helps to manage saline aquifers and reduce soil salinity. Such shallow wells range from 25 to 30 meters deep. This technology is very well-accepted by the land users.

2.2 技术的详细说明

说明:

The shallow well is a structure created in the ground by digging or drilling to access water resources. This example of shallow wells is their use in recharge areas to lower groundwater tables. The technology is a subproject of a larger LDD initiative. The technology has been promoted by the Land Development Department at Bua Yai district Nakhon Ratchasima province since 2014. The objectives of the main project are (1) to provide water resources in recharge areas for agriculture: (2) to reduce the amount of saline groundwater and (3) to set up positive economic impact measures.
The process of technology establishment comprises 1) a recharge area survey in salt-affected areas, 2) drilling shallow wells to 25-30 meters depth, 3) installing 5.5 hp gasoline pumps and testing water quality, 4) pumping groundwater and distributing it to the cultivated areas.
Shallow well technology has been implemented on the fields of Mr. Boonchu Supho, Ban Nong Mek, Moo 9, T.Dan Chang, A. Buayai, Nakhon Ratchasima Province. Mr. Boonchu Supho has 21 rai (approx. 3.4 hectares), undulating area with a 2-5% slope, situated at approx. 200 meters above sea level, with a tropical climate, and soil which is classified as being in the series of Kula Ronghai (Ki). This area is upland, and located in the recharge area. Mr. Boonchu Supho has 13 rai (approx. 2 hectares) of lowland rice fields and one shallow well.
In the past, water scarcity was the main issue with his land. Droughts resulted in water scarcity and low productivity. After excavating a shallow well in 2014, groundwater was used for 19 rai of cultivation. Due to soil salinity reduction, rice yields increased to 590 kg/rai (approx. 3700 kg/ha: an increase of approx. 47.4%). Sugar cane yield increased to 30 ton/rai. Moreover, land users can use land more efficiently with mixed plantations of banana, pineapples, sweet bamboo, chilies, galangal and lemongrass to generate income. Even with a drought in 2018, his land had enough water for cultivation, while rice fields in the surrounding area faced water scarcity problem.
In conclusion, the benefits of the shallow well are 1) lowering the groundwater table and reducing salinity, 2) enhancing rice and sugar cane yields, 3) ability to cultivate throughout the year and 4) better soil properties and a better environment. However, the disadvantage of the shallow well is that farmers have to pay for electricity (around 1,200 THB/ 9 months or 10,800 THB/year).

Moreover, land users have to paid for farm pond construction under farm pond project of LDD about 2,500 THB.

注释:

Nong Mek Village, Moo 9, Dan Chang Subdistrict, Bua Yai District, Nakhon Ratchasima Province located on the recharge area which has totally 1,000 rai. Recharge area is a type of upland where use for cassava and sugar cane planting. Most land users have not much knowledge and motivation on shallow well drilling. Hence, Land Development Department comes to train, solution on salt-affected soil with the project on prevents soil salinity, and to lower the groundwater table on recharge area since 2014. The shallow well technology has been implemented through the demonstration plot, which is the first learning center of salt-affected soil management on the recharge area

6.3 技术对渐变气候以及与气候相关的极端情况/灾害的暴露和敏感性(土地使用者认为的极端情况/灾害)

注释:

An opinion of the land user, there are many situations such as rain delay during 2014-2016, drought during December – April 201 and flood in rainy season while rain delay in 2018 can lead to water scarcity problem. However, that situation cannot impact farmland with shallow wells.

6.4 成本效益分析

技术收益与技术建立成本相比如何(从土地使用者的角度看)?
短期回报:

积极

长期回报:

非常积极

技术收益与技术维护成本/经常性成本相比如何(从土地使用者的角度看)?
短期回报:

积极

长期回报:

非常积极

注释:

Land users to pay a 2,000 baht machinery as a long-term investment to operate for several years and pay the electric fee for water pumping but land users can have 10,800 THB and the revenue daily, monthly and annually and reduce costs in the household

6.5 技术采用

  • 1-10%
在所有采用这项技术的人当中,有多少人是自发的,即未获得任何物质奖励/付款?:
  • 0-10%
注释:

Land user and other farmer have knowledge and understanding on an advantage of shallow well technology implemented. Some of them drill water well by themselves.

6.6 适应

最近是否对该技术进行了修改以适应不断变化的条件?:

其它(具体说明):

changing practice

具体说明技术的适应性(设计、材料/品种等):

Land users have modified water pump machine by use electric pump instead of a gasoline pump

6.7 该技术的优点/长处/机会

土地使用者眼中的长处/优势/机会
Reduce soil salinity
Save money by bringing rice and vegetables grown into household food.
Increase sales revenue, rice, sugarcane, pineapple, Papyrus, banana, lemongrass, galangal, chili, and sweet bamboo.
Save money by bringing rice and vegetables grown into household food.
编制者或其他关键资源人员认为的长处/优势/机会
Pumping water from shallow wells for agricultural use, can reduce groundwater table and prevent salinity that is a great measure on land degradation mitigation
The land user can have food from plant production from their farms. The land user can reduce household expenses. Left to sell, resulting in a daily, monthly and annual income and make a better life.
Biodiversity enhancement, there are many plants and living things such as earthworms, birds, fish, frogs, and insects. This is resulting in a balanced ecosystem.

6.8 技术的弱点/缺点/风险及其克服方法

土地使用者认为的弱点/缺点/风险 如何克服它们?
After one year of shallow wells implemented, land users must take care and maintain shallow wells as usual. Make an agreement on taking care of shallow wells after implemented.
To inform LDD when something is wrong
编制者或其他关键资源人员认为的弱点/缺点/风险 如何克服它们?
Other land users who are not participating. will not get knowledge about the use of shallow well to reduce the level of underground water. LDD staff / Land users participating in the project to advise or educate other farmers on how to join the project.
