The Cetacean Sirenian Indonesia

the Cetasi logo, from

My colleagues and I have been involved in marine mammal conservation in Indonesia for more than a decade now. In addition to our independent works, we have banded together to improve the marine mammal conservation practices. Our first endeavour was the establishment of a mailing list for marine mammal enthusiasts (Marine Mammals Indonesia), created in 2004 when Yahoo was the king of cyberspace. Then, nine years later, we catapulted our joint efforts further by creating an online stranding database ( We have also conducted some workshops (notably, I should say, the November 2013 national stranding workshop, in addition to several local workshops). Those workshops required funding, the proposals of which we wrote either as individuals or on behalf of other institutions (notably the Indonesian Biodiversity Research Center). 

However, we feel that it’s time now to have our own legal vehicle to conduct our conservation programs. At the very least, it would help with grant application. Thus, since the last few months, Februanty Purnomo (Yanti), Adityo Setiawan (Adit) and myself have been discussing the possibility of legally establishing an NGO fully dedicated to the conservation management of marine mammals. The NGO will cover, inter alia, bycatch and entanglement issues, cetacean watching tourism, biological and ecological assessments, marine mammal protected areas, and stranding management.

Paper on expenditures of business visitor at the Great Barrier Reef Australia

The Great Barrier Reef

Another paper published last year at Tourism Economics. Still have not got the online version, let alone the printed copy. But the abstract is below. I will update it once the PDF is available.

Mustika, P. L. K., Farr, M. and Stoeckl, N. (2014b), 'The potential implications of environmental deterioration on business and non-business visitor expenditures in a natural setting: a case study of Australia’s Great Barrier Reef', Tourism Economics.


Nature-based tourism can be an important source of income for regional economies, but relies on a healthy environment. Using data collected from business and non-business visitors to Australia’s coast adjacent to the Great Barrier Reef, the authors generate estimates of the potential financial impact of environmental degradation, demonstrating a novel way of testing and controlling for hypothetical response bias. More than 90% of non-business visitors and 67% of business visitors came to the region for at least one nature-related reason. Average daily expenditure was similar for both visitor segments (about $190), but the determinants of expenditure varied. All visitors reacted much more negatively to the prospect of environmental degradation than to a 20% increase in (local) prices, although business visitors were much less responsive than non-business visitors. Adjusting for hypothetical response bias, the authors estimate that substantial environmental degradation could reduce visitor expenditures (and thus local tourism incomes) by at least 17%.  

Update 3 August 2016:

The article received its issue number etc last June. You can download the copy here through the Tourism Economics website, or email me at putuliza at gmail dot com. The Harvard version of the citation is this:

New paper: Evaluating the potential disturbance from dolphin watching in Lovina

Happy New Year you all! Sorry for the silence, I've been trying to publish more paper since the last two months. Slow progress, but it's getting there. Hey, at least I published two papers last year (two is definitely not a big number, bad Icha, bad...), and one of them is this note on Marine Mammal Science with DOI 10.1111/mms/12188.

Mustika, P.L.K., A. Birtles, Y. Everingham and H. Marsh. 2014. Evaluating the potential disturbance from dolphin watching in Lovina, north Bali, Indonesia. Marine Mammal Science. DOI 10.1111/mms/12188.
