On that respect, the procedure of Community Health Impact Assessment (HIA) in Thailand could serve as a model articulating participatory methods with science and policy to improve knowledge and foster its implementation through co-designed and evidence-informed policies (Lajaunie, 2014). In the perspective of the ASEAN (Association of Southeast Asian States) Economic Community to be built by the end of 2015, it became necessary to prevent transboundary health impacts by integrating surveillance and alert systems. ASEAN member states charged Thailand to develop the framework of HIA in ASEAN and to foster its implementation. Thailand’s leadership resides in the fact that the country acknowledged a constitutional value to HIA and proposed to institutionalise HIA at the regional level. 7KH&KLDQJ0DL'HFODUDWLRQRXWFRPHRIWKHƬUVW $VLD 3DFLƬF +,$ FRQIHUHQFH KHOG LQ 7KDLODQG DƯUPV WKDW +,$ LV pRQH RI WKH FULWLFDO WRROV IRU developing healthy public policies that intend to provide an enabling social and physical environment that promotes having a healthy OLIHDQGRƪHUVSROLF\RSWLRQVSHRSOHFDQDFFHVVq (Chiang Mai Declaration, 2008).

Participatory studies on rodentborne diseases and communities assessments ,IWKH&RQVWLWXWLRQGHWDLOVGLƪHUHQWW\SHVRI+,$ the Community HIA is remarkable as it empowers communities: communities can conduct HIAs and use information in order to share, discuss and negotiate during public policy making SURFHVVHV ZKLFK FDQ OHDG WR WKH PRVW EHQHƬFLDO development for community’s well-being. Rodents are particularly appropriate biological models to investigate the relation between humans and their environment, while assessing health through rodent-borne diseases. On a research project aiming to understand the consequences of environmental changes on the evolution of communities of rodents, their parasites and their pathogens in South-East Asia (CERoPath project), interviews about knowledge and perception regarding rodents have been conducted in several villages of Thailand and Northern Lao PDR where rodent trappings have been organised. The Community HIA is considered as a joint learning process in the society.

The HIA responded to a participatory learning process for local people having as objectives: to investigate socioeconomic and population changes due to the introduction of orange plantations as commercial crops, to explore local people’s health problems related to the orange crops, to identify the scope of HIA of the orange plantations in the three districts concerned.

The HIA underlined the great importance of the learning process as the local community learnt how to comprehend a holistic approach of health (Sabrum, 2008). Local people participated in the design of the study method, and in the data investigation, collection and processing. We can underline that it was a real participatory study: it appeared that the issues related to the deterioration of the watershed ecosystem were until then ignored. They found the evidences of the link between the health impacts and the orange plantations while no key stakeholders DFDGHPLFVSODQWDWLRQVRZQHUVRUKHDOWKRƯFHUV  accepted to join the study.

The interviews also aimed at determining information that could have an implication for conservation or diseases risks and then at developing questionnaires for a quantitative approach. They could also contribute to assess the impacts of public health policies or prevention campaigns in helping to determine the evolution of risks perception whether it is related to zoonotic diseases or other kind of risks (Della Rossa, 2013). As we have seen, in Thailand the Community HIA can be launched by any academic institute and such interviews reveal the need to conduct HIAs integrating the concern of zoonotic diseases into the assessment of policies having indirect impact on the emergence or spread of those diseases. +,$KDVEHHQGHƬQHGDVDpPXOWLGLVFLSOLQDU\SURFHVV within which a range of evidence about the health HƪHFWVRIDSURSRVDOLVFRQVLGHUHGLQDVWUXFWXUHG framework.

Scientists working on zoonotic diseases with a holistic approach in ASEAN countries could seize the opportunity to include their concerns into the Community HIA legal framework, using its GLƪHUHQW SKDVHV VFUHHQLQJ VFRSLQJ DSSUDLVDO reporting, monitoring). The interest of using HIA resides in the fact that WKHLGHQWLƬFDWLRQRILVVXHVOLQNHGZLWKSROLFLHVZLOO command the intervention of decision-makers to solve those issues as HIA is legally binding and at the same time it will allow the citizens to be involved into the decision-making process. It would then respond to the need of evidencebased policies regarding emerging diseases (WHO SEARO/WPRO, 2005). HIA in Thailand is not originally focusing on zoonotic diseases. Nevertheless, in the context of zoonotic diseases, integrating this health concern into HIA seems relevant and as the drivers and the GLPNEWS | APRIL 2015 32 Figure 1: )UDJPHQWHGIRUHVWLQWKHVWXG\DUHD transmission dynamic of zoonotic diseases need a better understanding (Cosson et al., 2014), the cooperation of scientists and decision-makers IURPGLƪHUHQWVHFWRUVDQGGLVFLSOLQHVFRXOGKHOSWR design innovative strategies (Jancloes et al., 2014).
