2. Materials and Methods
Tourism data were obtained by request (collated Oct. 2019) from the Ministère du Tourisme on Madagascar. The Ministry supplied data covering the period 2007-2018 that included the total number of overseas visitors (tourists) each year and estimated income from tourism for each year (
Table 1). Wollenberg
et al.’s [
35] value of 17% (percentage of tourists who were ecotourists) was applied to the yearly tourist num-bers to provide an estimate for the number of ecotourists visiting Madagascar each year (
Table 1).
To estimate the income values generated from ecotourism, the yearly number of ecotourists (
Table 1b) were multiplied with published conversion values presented by both Wollenberg et al. [
35] and Dixon & Pagiola [
26], in each case the published values were adjusted for inflation in US
$ to 2019. Estimation 1 was calculated using Wollenberg
et al.’s [
35] conversion value with yearly ecotourist numbers. Estimation 2 used Dixon & Pagiola’s [
26] conversion values, who provided an upper and lower value. Hence there were two calculations performed and two sets of estimates, upper and lower values, presented.
CITES data were obtained from the CITES Trade database (
https://trade.cites.org/). These data were collated on 23rd Dec. 2019 using the following criteria; export country = Madagascar, source = wild, purpose = commercial, terms = live. These criteria were applied while the ‘Search by taxon’ was left empty to collect trade data records across all CITES listed taxa groups, animals and plants, for the period 2007-2018. These data were downloaded in an excel format for analysis and presentation.
Flora and fauna trade prices were extracted from published literature [
37,
42] and adjusted for inflation, in US
$, for each year over the period. For plants, there were no trade structure price data available other than a single average export price [
49]. The price structure reported for animals displayed a decrease in the order of two magnitude from export to collector, hence, it has been assumed here that a similar price structure would be observed for plants. Thus, the average plant price has been reduced by two-fold to provide a general indicator of price at the collector level.
4. Discussion
Over the whole time period for which data exists (2007–2018), the international live trade in Malagasy herpetofauna generated revenues estimated at a total of US
$401,470 reaching local Malagasy people. Taking just the upper estimate, for the reptile and amphibian focused wildlife tourism, it was valued at over US
$51 million while the general figure was estimated at US
$17-46 million. However, both these revenue estimates were greater than the estimated revenue generated from the wildlife trade, though actually how much flows to reach the local people is unknown. For comparison however, in just 2018, Madagascar’s top revenue generators ranged from; firstly, coffee, tea and spices (valued at US
$1 billion; on its own vanilla was worth US
$855.4 million and cloves US
$149 million) to tenth place, mineral fuels, including oil (valued at US
$51.5 million) [
50]. The vast differences highlighted here between top in-come generators and the trade in wildlife, potentially, offers some justification for the government of Madagascar’s apparent lack of attention and focus to issues raised by this trade type. It can sometimes be forgotten by conservationists that Madagascar’s government are often dealing with perceived greater priorities and with minimal resources.
However, it should also be remembered that this study is presenting wildlife trade data only for CITES listed species. There would also be much trade in non-CITES listed species happening in parallel to these data presented here. Therefore, the monetary values presented should be viewed as minimum values. Furthermore, whilst CITES listed species do have non-detrimental findings (NDFs – albeit NDFs remain highly questionable in terms of population data used and robustness of outputs) that allow quotas to be assigned to a species limiting the number of individuals they are traded in, this is not the case for non-CITES listed species. Thus, questions over the sustainability of trade in all species of flora and fauna remain. However, by presenting both flora and fauna data together within this study does allow for a more complete ‘picture’ of the wildlife trade on Madagascar, whilst highlighting that many questions remain unanswered over the sustainability and management of its wildlife.
Whilst tourism with a herpetological focus was over two magnitudes of difference higher than that generated from the international live trade, the revenue was focused towards local communities located adjacent to NPs benefiting. Conversely, those involved with the live trade were more geographically dispersed and, likely, with no association to a national park. Hence, the two sources of revenue generation were possibly complementary to each other in that they could potentially engage with different sets of local people. Therefore, they should not be seen as alternatives, but rather can operate side by side, as long as it is sustainably conducted. Thus, both avenues to valorisation of wildlife raise not only the levels of revenue generated but also the opportunities to engage in revenue generation for a wide spectrum of local communities. However, one has to be careful of the wider dynamics involved. For example, one hotel Northeast of Mahajunga, Anjajavy, attempted to train individuals from the adjacent, remote, village to work in the hotel (author, pers obs.). However, due to the multiple juxtapositions between the individuals and the western facing hotel, the training of local people to work within the hotel and, thus, provide local benefits had very mixed results. This resulted in the hotel ceased trying to utilize staff from the local village due to several reasons, but instead recruited individuals with more western ‘standards’ exposure from major towns and importing them to work at the hotel but living in the local village. These new recruits were from different tribes with very different social / behavioural mannerisms, outlooks and more western experiences. Yet they were expected to be both located within the local village and welcomed by those living there. The impacts were extremely wide ranging and both negative and positive.
Despite the short-term economic benefits, the long-term conservation impacts re-sulting from the current scope and scale of the consumptive use of wildlife was being increasingly brought into question [
1,
11]. However, the potential negative impacts of unsustainable exploitation are not limited to extractive use of Madagascar’s flora and fauna alone. For example, broad scale issues can arise from ecotourism operators’ environmental responsibility, such as deleterious impacts from the demand for water supplies or waste product disposal [
30]. Alternatively, at a finer scale, irresponsible ecotourism can also bring net negative impacts on both the conservation and welfare of wild animals, including reptiles [
32,
33]. For example, regular, close proximity of tourists with free-ranging wildlife can negatively impact an array of animal behaviors, such as breeding [
51] or foraging [
52]. Direct physical contact with wild caught wildlife can also lead to the unintentional transfer of zoonotic diseases [
35], the death of individual animals or to species, potentially threatened species, being brought into captivity to show-off to tourists. Often these types of negative impacts are difficult to detect, especially by tourists themselves [
32], while different attitudes and societal expectations further complicate such decision-making [
33].
Both trade types reported here, whilst generating income, raise questions over their sustainability, both from direct and indirect effects. However, it is imperative that Madagascar’s authorities seek to implement much more robust and greater detailed reporting of the structures operating within both trade types. For example, taxes are collected from both trade types and there are potential benefits to government, local communities and conservation from implementing better monitoring. However, presently, there is a lack of knowledge and openness as to both the supply chain networks and financial flows operating within the country. Hence, to allow both fuller evaluation and greater management of these income generation types, much greater effort needs to be focused at reporting on and managing both supply chain networks and financial flows. This would permit adjustment of higher financial flows away from wildlife exporters / foreign businesses and more towards government and local communities; importantly raising the benefits gained by local communities from maintaining local wildlife and habitats. Considering local communities are a conservation concern in places, this could be managed to benefit both local people and conservation.
No previous study has sought to estimate and compare such complex scenarios, especially for a country that has such a high conservation profile and in need of such evidence upon which to make more robust and sustainable management decisions for the national good. Ultimately, there are positives and negatives associated with both the live trade in wildlife and ecotourism. However, it will be the long-term sustainability with minimum environmental impacts that follow both activities that managers will need to ensure going forward. These will be multi-dimensional, ranging across species and ecosystems to human dimensions, and spanning both temporal and spatial scales. Hence, balancing social demands with environmental capacity to minimise impacts and maintain sustainability should be the goal of government and managers alike.
