根据哪些标准和/或指标（与战略无关），在确定建议的实践和相应的技术是否被认为是“最佳”时，应该基于哪些标准和/或指标（与战略无关）？

production improved during drought season which is unusual.

最佳实践解决的主要问题

Crops and vegetable poor growth and production during drought season.  

概述最佳实践解决的具体土地退化问题

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.

具体说明最佳实践的目标

To improve crops and vegetables production during the drought season

本技术的简要说明和技术规范

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

是

通过什么手段？:

• 参与途径

描述现场影响（按类别划分的两类主要影响）

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.

描述两个主要的场外影响（即不是发生在现场，而是发生在周围区域）

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

对生物多样性和气候变化的影响

解释原因:

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
