Folk classification and traditional uses of Cyperus esculentus,  a neglected and underutilized species in Benin

Abstract. Adjahossou VN, Gbemavo DSJC, Abidja S, Laly J, Gbaguidi AA, Anagonou AD. 2021. Folk classification and traditional uses of Cyperus esculentus, a neglected and underutilized species in Benin. Biodiversitas 22: 2972-2979. The sweet pea or tigernut (Cyperus esculentus L.) has very high potential to be developed but is considered a neglected and underutilized plant in Benin. The current study aims to investigate the indigenous knowledge related to local diversity, production and uses of various landrace types of tigernut grown in its production areas in Benin. Using Participatory Research Appraisal (PRA) method, we surveyed 113 tigernut farmers in different regions of production in Atacora Department, Benin. Univariate statistics were performed to describe and compare tigernut farmers' responses on botanical and agronomic criteria. We found that the tigernut farmers in the studied area distinguished three landraces of C. esculentus. Two landrace types produced yellow-skinned tubers and the other produced black-skinned tubers. Economic value, agro-morphological traits and organoleptic quality were the criteria considered by the farmers when choosing the type of landrace to cultivate. According to the farmers, the attacks of the tubers by earthworms and termites constituted the main constraints of the production of tigernut. Local people used the species mainly for food, while small proportion was for medicine (e.g., for aphrodisiac) and soil fertilization purposes. This study implies that C. esculentus in Benin deserves better attention to be conserved and developed.

In 2008, the first Coal Bed Methane (CBM) PSC was signed in Indonesia. To date, 54 CBM PSCs have been awarded to explore and develop CBM Block in Indonesia. Twelve years later, only one PSC has submitted a Plan of Development but has not yet produced gas commercially. Most CBM PSCs have been struggling during the 10 years’ exploration period and some may receive extensions for 3 years under specific conditions. The lack of integrated authorities’ approval in the overlay of coal mining and natural gas production areas has become a great obstacle for CBM Development. Besides that, the government regulations in CBM activities have defects in PSC contract terms that may lead marginal economic value for contractors, especially due to high investment during the early development (C. Irawan, 2017). On the other hand, drilling regulations, Pipe Classing standards and Testing Standards following the Oil and Gas standards are too expensive for CBM Investment. According to our observations, CBM Regulations in Indonesia should be modified starting from the Exploration period, Production Sharing Contract Terms and Standard Operating Procedures to suit Indonesian CBM characteristics. Good coordination within government departments is a must for the success of CBM Exploration and Development.
