The bujja system is a method of agricultural land reclamation practiced both historically and presently in Cananganam. The system works in conjunction with the Cananganamese long year, and with practices and techniques innovated both locally and from foreign introductions since 1500 BCE.
In Cananganamese, the word bujja derives from either the dative verbal noun form of "to farm", or from a compounding of bud- "to farm" and ya "enclosure".
The first mention of Lunar/Solar crops is in the Apaksratsree era, where it references a dispute between two farmers over damage done to the other's bujja which was brought to the attention of several religious authorities. Depictions of the style of farming is made more prevalent in art as it became more common and typical of Canamic agriculture. The bujja system was advantageous to other systems of agriculture as it reduced the need to water the plants and risk overwatering, provided a healthy fertilizer source from the fish, and with their connections to waterways boats could easily be utilized for transporting collected goods from plot to plot or town to town. These methods of farming, however, were significantly at risk to mismanaged flood seasons as high flood waters could sometimes easily ruin significant tracts of land which could happen usually after cyclones and strong storms.
The method was significant for Naguan civilizations as it removed the need for draft animals for pulling wagons and ploughs, becoming a factor in the rise of Nagu as a primary center of civilization during the early medieval period as a source of wealth and development. The bujja system would suffer during the centuries following the collapse of the Cananganamese empire as the plumbing, damming, and dike systems which had significantly contributed to the control of flood levels fell into disrepair. This disrepair led to massive famines contributing to the collapse of the empire and the rise of city states of reduced size.
Since the mechanization of the farming industry and the limitation of ground vehicles in southern Nagu, the farming methods have seen a revival and play an integral role in the economies of Cananganam and Mujansa especially, which benefit to their status as significant agricultural producers in the region.
Crop rotation plays a significant role in Cananganamese agricultural practices, as in many documents found since the 3rd century BCE make mentions of crop rotation and Moon/Sun crops.
Two Year System
The most common system practiced in the medieval period was the two year field system. This system involved the following variations which would be interchangeably used at the end of the short year:
- Moon Year Crops include: Cardamom - Chia - Lupine - Peanut
- Sun Year Crops include: Amaranth - Asafoetida - Arrowroot - Millet - Taro - Olluco
Some farmers also utilize a three year system where after the planting of the moon year plants, they will fallow the field instead for a year before planting sun year crops.
Three-Four Year System
The three and four year system was built on top of the two year system and matched with the Cananganamese long year. This system is typically some variation of legumes, followed fallowing, and then some variation of the traditional Sun Year crops for two short years.
Orchard farming plays a significant role in Cananganamese farming methods, as the trees add to the stability of the land plots and their survival in times of flooding aiding to their common usage. In addition to this benefit, the trees are routinely cut down when their fruit bearing period ends for use in construction or tool making.
