คำอธิบายแบบสั้น ๆ ของวิธีปฏิบัติที่ดีที่สุด

during the drought season, crops and vegetables require water and soil moisture.  Drip irrigation, vegetable mulge and screen technologies provide sufficient water and soil moiture throughout the year for crops and vegetables.  its simple and effective where production improved a lot.  |

On the basis of which criteria and/or indicator(s) (not related to The Strategy) the proposed practice and corresponding technology has been considered as 'best'?

production improved during drought season which is unusual.

Main problems addressed by the best practice

Crops and vegetable poor growth and production during drought season.  

Outline specific land degradation problems addressed by the best practice

Water resources scarcity and long drought season.  Vegetables require water to grow and bucket irrigation system provide sufficient water for plants to grow and production improve.

Specify the objectives of the best practice

To improve crops and vegetables production during the drought season

Drip irrigation - bucket water with necessary pipes are extended to crops and vegetables to keep them access to moisture soil.  Drip irrigation technology, to supplement the rainfall in ensuring un-interrupted optimum soil moisture conditions. |

Short description and technical specifications of the technology

To promote favourable growing conditions against the hot humid climate of this period, the use of the vegetative mulch, screen house and drip irrigation technologies are highly recommended for the production of the off-season vegetables.
• Vegetative Mulch technology: reduce the soil temperature (carrots, Irish potatoes, etc.), conserve soil moisture and suppress weeds.
• The screen technology: reduces the amount of direct sunlight necessary for the initial growth transplanted seedlings of the vegetables; enhance the fruit-set of tomatoes, capsicum, etc.,  by reducing the impact of the rainfall
• Drip irrigation technology, to supplement the rainfall in ensuring un-interrupted optimum soil moisture conditions.
Both technologies are recommended for the production of vegetable during the December to May period

Awareness and introduction of the technology to farmers and communit at large

Was the population living in the location and/or nearby involved in the development of the technology?

ใช่

By means of what?

• Participatory approaches

Describe on-site impacts (the major two impacts by category)

simple and efficiency.  not high tech but user friendly and everyone could use.
improve and more revenue collected.  community access to vegetables all year including cultural function. decrease import of vegetables from overseas.
improve production all year round.

Describe the major two off-site (i.e. not occurring in the location but in the surrounding areas) impacts

same as the onsite as technology have been transfered to nearby site

Impact on biodiversity and climate change

Explain the reasons:

maintain biodiversity from threaten and also contribute as an adaptation option especially with crops affected as impact of climate change.  less ans less rainfall in the future so the introduction of such technologies will help crops withstand

Related to technical aspects

Simple and user friendly technology which could make big difference as far as farmers are concern.  Low tech but effective which might have big different in the result.
