                       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).



               Property characteristics of the natural environment


                       The mentioned area, the Annual Mean rainfall is 2,778.30 mm., which is at the moisture

               level.

                       The area is flat and 1 meter from the mean seal level. The soil is very deep with the depth

               more than 120 centimeters. The top soil texture is fine clay and the bottom soil texture is clay. The
               level of soil organic matter is high (>3%). The ground water cannot be utilized. The water at the

               soil surface is at the level which is more than enough. Regarding the water quality (not treated

               yet), the water can be used for agriculture only. The salinity value of soil is between 2-8 dS/m.
