Phase 1 of the project which entails identification of a cluster of community owned farms where manure management is a problem has already been done. This phase ensures that farmers who have a definite need of manure management are identified, selected and educated about biogas production from piggery manure, and hence community participation is assured. Pictures in Figures 3 & 4 were taken on farms owned by participating farmers during the farmer survey activity. Subsequently, a farmer shall be selected using the following criteria, for housing the mobile biogas plant on his/her farm: i) To be eligible for housing and hosting the mobile biogas plant, the farm must bewithin a radius of 100 km from Gaborone, for ease of monitoring by project staff. ii) The farmer must be having a minimum of 15 sows. iii) The farmer must have been in pig production for at least five (5) consecutive years, and still be willing to continue. iv) The farm and all other properties of the owner must not be attached by a third party financier, to ensure that the piggery production is not under threat of liquidation. v) The types of feed used by the farmer must be approved by the project team and the staff of the piggery section of the Ministry of Agriculture. This is to ensure that the farmer feeds only conventional acceptable pig feed for the entire course of the study. vi) The selected farmer must be willing to host farmers when they are brought to his/her farm for biogas technology demonstrations. vii) Equal opportunity shall be given to all farmers irrespective of gender. The second phase shall be the actual generation of energy from biogas, with the objective of ensuring that farmers learn how the technology operates so that they can build their own systems if they so wish. Farmers shall avail their manure to the biogas facility (Figure 6) for conversion into energy and thereby get relieved from having manure heaps and piles on farms.

The initial phase of this project was the identification of the incidence of piggery waste as a problem in the South East Agricultural region. Having positively identified piggery waste as a problem, the second phase is therefore to manage the piggery waste in such a way that it enriches the lives of the pig farming community. The project shall ensure that piggery waste (animal) is quantified and processed in the piggery value chain and ultimately used to save the farmer heating costs. Inevitably, by so doing the project shall also be mitigating the detrimental effects of methane in the environment, and hence removing a greenhouse gas from the atmosphere. Energy generated from piggery waste using biogas technology shall be used by farmers for cooking and space heating, and since piggery waste is a renewable resource, the energy can be generated indefinitely. The anchor of this project is ensuring that farmers know how to manage piggery waste, and even turn it into a valuable resource, which is combustible methane which they can use for cooking and space heating.
