Drought tolerance of Acacia karroo, a native tree species to South Africa, in Beijing

Acacia karroo is an indigenous, strong drought-tolerant and widely planted tree in South Africa. In order to match the plant with its adaptation to forest sites in China, it is important to know the drought-tolerance of this species under Chinese forest site conditions. Our study was carried out in cinnamon soils in Beijing and with Platycladus orientalis, the most drought-tolerant tree in Beijing, as control. Physiological parameters of young plants of the trees were measured and divided into three groups in response to soil drying. The first group included root activity, ABA content in roots and peroxidase (POD) activity in leaves. Their values changed similarly to those of P. orientalis and dramatically increased to maximum values when the soil water content (SWC) decreased from its normal level of 20% to 7.6% where the three indices decreased dramatically when SWC was reduced further from 7.6%. The second group of parameters included the contents of proline, soluble protein and malondialdehyde (MDA). Their values showed greater variation than those of P. orientalis and significantly increased when SWC decreased from 20% in response to soil drying. However, the proline and soluble protein contents fluctuated in A. karroo at a lower level than those in P. orientalis. In contrast, the content of MDA in A. karroo was much higher than that in P. orientalis which almost did not increase in the drying soil. The third group of parameters consisted of soluble sugar, superoxide dismutase (SOD) and catalase (CAT). These parameters showed greater diversity and fluctuations among the three varieties of A. karroo compared with the control in response to soil drying. These results suggest that A. karroo is characterized as a strong, drought tolerant species in most of physiological parameters but weaker than P. orientalis in membrane lipid antioxidation.

Farmers’ Willingness to Pay for the Provision of Ecosystem Services to Enhance Agricultural Production in Sene East District,Ghana

This study investigated farmers’ willingness to pay (WTP) by trading food crop as payment for the provision of ecosystem services (ES) to enhance agricultural production and factors influencing their WTP through integrating timber trees on their farmlands in Sene East district, Ghana. A total of 177 farmers were selected from six communities using stratified and simple random sampling. One-on-one interviews were conducted using structured questionnaires. The contingent valuation method was used to gather the data on farmers’ WTP for the provision of ES. A multiple linear regression was run to test factors influencing farmers’ WTP. The results showed that 59% of farmers were willing to pay for the provision of ES. Gender, age, educational status, farmers’ perception to climate change and access to land significantly (p < .001) and positively influence farmers’ WTP. This study identified difficulties in acquiring land, insecure tree tenure and indiscriminate logging as governance challenges that should be addressed to support farmers’ WTP for the provision of ES to enhance agricultural production.
