In the traditional perspective, Indonesia is rich in flora or plants. So many tribes and small groups of people use over 6,000 different species of plants for remedies and such. These people also use the flowers to sell to other merchants to make a small profit.
There is also little commercial farming performed on the humus-rich lands of Indonesia. Most people prefer subsistence farming over commercial farming because large groups of workers must clear the forests that keep the land so rich in humus in order to farm over large plots of land. About 45% of people in Indonesia work in an agricultural-based job. This accounts for 17% of the GDP. Since Indonesia has many highlands, the people use terraced farming, which is the farming of products on hills and mountains by creating terraces throughout the different heights of the raised land. This really only helps the family the farmer is working for/with. And the population continues to increase. So the more mouths to feed, the more the country must spend on getting food imports, making them spend less money on the infrastructure. Therefore, the Level of Development, or LOD, is under developed or, in some cases, developing. And the Human Development Index or HDI averages around 0.6%.
