The phenomenological case study covers the limited research on Chinese students‟ experiences of nature in a tropical rainforest in Thailand. Macau is a very small place with only 20 % of natural resources remaining but Chinese students are born to be detached from these natural environments. Their comfortable lifestyle leads to a rise of unsustainable behavior such as an increased in consumption and household waste. With numerous researches that review the benefits of nature including an enhancement in environmental friendly behavior, a 7 d self-funded experiential learning program in a tropical rainforest in Thailand in 2015 was initiated in fostering 12 Chinese students‟ pro-environmental identity and behavior. Findings show the majority of students‟ pro-environmental identity and behavior is enhanced and they are trying to reconnect with the natural environment more often than before.

Modelling Methods

Abstract. To evaluate the effects of variations in rainfall on groundwater, long-term rainfall records were used to simulate groundwater levels over the period 1953-96 at an experimental catchment in south-east Zimbabwe. Two different modelling methods were adopted. Firstly, a soil water balance model (ACRU) simulated drainage from daily rainfall and evaporative demand; groundwater levels were predicted as a function of drainage, specific yield and water table height. Secondly, the cumulative rainfall departure method was used to model groundwater levels from monthly rainfall. Both methods simulated observed groundwater levels over the period 1992-96 successfully, and long-term simulated trends in historical levels were comparable. Results suggest that large perturbations in groundwater levels area a normal feature of the response of a shallow aquifer to variations in rainfall. Long-term trends in groundwater levels are apparent and reflect the effect of cycles in rainfall. Average end of dry season water levels were simulated to be almost 3 m higher in the late 1970s compared to those of the early 1990s. The simulated effect of prolonged low rainfall on groundwater levels was particularly severe during the period 1981-92 with a series of low recharge years unprecedented in the earlier record. More recently, above average rainfall has resulted in generally higher groundwater levels. The modelling methods described may be applied in the development of guidelines for groundwater schemes to help ensure safe long-term yields and to predict future stress on groundwater resources in low rainfall periods; they are being developed to evaluate the effects of land use and management change on groundwater resources.

Origin Energy—on behalf of the Australia Pacific LNG Project, the upstream tenures for which occupy some 570,000 ha—has established an offsets project in the Brigalow Belt of Queensland. This belt of Acacia woodland runs between the tropical rainforest of the coast and the semi-arid interior of Queensland, and is one of 15 bio-regions in Queensland. Its reduction to less than 8% of its distribution makes it a significant part of Australia's natural environment. The offsets project has the aim of re-establishing areas of Brigalow and associated vegetation communities and fauna habitats for impacts on matters of federal or state significance. This should result in a long-term reduction in environmental impacts. Given the long-term decline in Queensland's biodiversity, such work is vital and its associated challenges—such as gaining long-term access to and protection of appropriate land, comparatively new and evolving regulatory requirements and, at times, working on the edge of scientific knowledge—requires persistence and innovation. This extended abstract presents valuable lessons learned to help inform future offsetting projects.
