The A·ba Cha·a system is an indigenous regenerative swidden practice in which more than thirty crop varieties are grown together in a single hill plot without industrial inputs, structured by a twelve-month cycle of farming and ritual observance. It starts with A·ba O·pata, the plot selection ritual, and ends with Wangala, the post-harvest thanksgiving to the creator deity Misi Saljong, whose conclusion marks the beginning of the next farming cycle.
Cotton (kil) occupies the crest of the hill; rice is planted at the foot, where moisture is retained - a spatial ordering that reflects a refined indigenous knowledge of hill topography. Cotton in this system is not a commodity: it is invoked in sacred chant, carried as a funeral offering for the deceased to cultivate in the afterworld, and was historically the primary medium of inter-ethnic exchange with plains communities.
The A.ba Cotton - Gossypium arboreum race cernuum is a short staple indigenous fibre which is ginned using a traditional tool, the Kelka, then hand-opened, hand-carded and entirely handspun using a drop spindle Takuri. The spinning tradition survives with a single known practitioner. A revival of the full processing ecosystem is underway.
