Definition for Home Garden1 1. A piece of land which has a dwelling house and some form of cultivation can be considered as a home garden if the total area of the piece of land is twenty or less than twenty perches. 2. A piece of land which has a dwelling house and some form of cultivation, if total land areas is more than twenty perches can also be considered as a home garden if following two conditions are satisfied. a. It is mainly meant for residential purposes. b. A produce of cultivated land in the home garden is largely for home consumption. Examples for Home Garden a) A land of extent 20 perches or less has a dwelling house and a few bearing coconut trees. b) A land of 20 perches or less, has a dwelling house and having extensive cultivation mainly for commercial purposes By definition (1) this land can be considered as a home garden c) A two acre land has dwelling house. Although the extent covered by a house is comparatively small and few crops are grown mainly for home consumption. According to definition (2) this land is also a home garden. d) A small house in a two roods land. But the usable land has been intensively cultivated with vegetable crops which are mainly for sale. Although this land has a dwelling house and also extent is small, as the produce from the land is not mainly for home consumption, it will not be treated as a home garden. However, in this survey cases like (d) have been treated as a home garden by excluding the area under commercial cultivation. For an example a one acre land with cinnamon cultivation (commercial purpose) also having a dwelling house, a small area around the house, may be 20 perches or less was separated out from the total land and considered as a home garden. Rest of the land was not counted to the home garden area and it was treated as land area under commercial cultivation. 1 Department of Census and Statistics, Sri Lanka. 1 Conversion Factors All figures in the data tables are given in hectares. However, only total figures of all tables were converted into acres and given in a separate row at the end of each table. Due to inadequate space of the tables it is not possible to accommodate all figures in both units. The following conversion factors can be used to convert hectares into acres or perches. Metric Conversion factor Equivalent Unit Imperial Unit Hectare Multiply by 2.47 Acre Hectare Multiply by 395 Perches Note: The home garden total extents given in the last two rows of the tables are presented as rounded figures without decimals. In some cases, when you are totaling the extent figures of the tables, total and grand total figures may slightly vary due to the adding of decimals. 2 1.
