4. To build economic impact which is useful (Opportunities to increase incomes or
employment)
Incomes from selling products and net incomes
The period in planting to harvesting nipa palm sugar from the first time takes about 6 years.
Therefore, in this first period, farmers do not have incomes from nipa palm plantations and will
start having incomes from the 6th year on. Regarding the period in producing nipa palm sugar,
yields can be given for 4 months in a year.
- In an area of 1 rai, yields of nipa palm sugar can be harvested for 300 kilograms per
rai per year.
- The selling price is 1.76 USD per kilogram. Therefore, the total income: 300*1.76 =
328 USD.
Besides making nipa palm sugar, farmers who grow nipa palms can create income from
other products such as sewing nipa palm leaves for palm leaf thatch roofing, nipa palm vinegar,
nipa palm leaves used to make cigarettes, making distilled liquor and making Nam Tan Tuoy (cup
sugar).
