Bitter Sweet Dutch Chocolate Industry

Living in a city comes with lifestyles created for the functioning and identity formation of city actors and its citizens. They portray how modern one has become by undertaking that lifestyle. Indeed one such lifestyle is associated with chocolate. Occasions such as Valentine and Easter are linked with the giving of chocolates as signs of showing love.  The celebration of Valentine’s Day, Easter have been synonymous with the use of chocolates within Dutch communities.

Their use has created a certain lifestyle which identifies one as being from a city and also seen as a “modern” citizen. The use of chocolates shows how much you love or care about someone.  The increase of this lifestyle has led to the institutionalization of chocolatier competitions such as Benelux Chocolatier Competition organised in big cities of the North such as Brussels and Amsterdam.

Cocoa also known as Theobroma cacao meaning the ‘food of the gods’, originated from the rainforests of Central America where on “modern maps, southern Mexico Yucatan peninsula, Guatemala, Belize, El Salvador and Honduras are located”(Bond, 2011). Bond explains that “The discovery and early use of cocoa are intimately linked with the ancient cultures of these areas – the Olmec’s (1500–400 bc), Mayans culture (250–900 ad) and later the Aztecs (ca. 800 AD to mid-sixteenth century)”.

The Mayans first started using the cocoa as a drink for its elites to the extent that the beans were used as currency(Bond, 2011). This cash crop has maintained its importance in society from being cultivated in countries in West Africa to importing countries like the Netherlands. Being able to produce much more tonnes a year reflects in the foreign exchange a  country earns. The International Cocoa Organisation (ICCO), 2018 quotes the price of cocoa at $2386.23 per tonne as at the 16 of July 2018.

“The Netherlands used to be the world’s main importer of cocoa beans having lost the spot to Belgium in 2016 and the second largest cocoa grinder” Ministry of Foreign Affairs, CBI 2017.    The Dutch ministry of Foreign affairs states that the Dutch spend around 23 euros per capita on chocolate products in 2015 and the Dutch are noted to have increased exports of semi-finished cocoa products between 2014 and 2015 by 6%. The ministry also reports in 2015 that trend watchers in the Netherlands say ‘the Dutch increasingly want a high-quality chocolate and are willing to pay for that quality”. This makes chocolate making one of the urban lifestyles of luxury in the Dutch society. Being inquisitive enough, I decided to investigate where the cocoa used in Delft comes from. The city of Delft is noted to have some of the best chocolate firms in the Netherlands. Visiting the chocolate firm of Van Der Burgh I asked: “where does your cocoa come from “? The woman happily said “Ivory coast”.  This confirms the information by the Ministry of Foreign Affairs, CBI 2017 that, The Netherlands imports roughly 85% of cocoa beans from West Africa and some from Latin America.

Capture

The city of Delft boasts of one of the best chocolate firms in the Netherlands which is not only handmade and of high quality, but also hand packaged. To Van Der Burgh, ‘chocolate must always be a present”. This ideology has enabled the firm to carve a brand for itself, having evolved from a small beginning to their present-day location in the historic city centre. Being a tourist destination that attracts all kinds of people from different countries.

 

 

Delft is increasingly becoming a market for different nationalities. The historic city centre boasts of hosting social events and markets that invites people of all walks of life. The citing of this small handmaid chocolate firm is not only patronised by the Dutch but all manner of people from different cultures. This brand has catapulted them into having cooperation with Michelin Star Chef Niven Kunz, who is seen as the best ‘vegetable chef” in the Netherlands. Again the company can boast of another cooperation with KLM enabling them to serve passengers with the best of chocolate by Van Der Burgh.

 

 

Africa during the colonial times produced raw materials for industries in the global north and such was Cocoa. As remnants of colonization, West African countries produce two-thirds of the world’s cocoa beans. With the Ivory Coast being the first and Ghana taking the second highest exporter according to the International Cocoa Organisation (ICCO) 2017, cocoa Barometer. For cocoa to be exported, it needs strategic preparation by both farmers and governments of the two countries to ensure maximum yields. In Ghana, the Ghana Cocoa Board borrows to buy the cocoa from the farmers for exports.

Before the cocoa is being exported, it needs to go through a process of fermentation for some days before drying. This fermentation is important to have a certain quality of beans. Traditionally designed mats made of bamboo serves as driers which makes it easier to fold when the rains are about to fall. The drying takes about two weeks before a farmer can sell it to the cocoa buyers in the various villages.

The coming of such an industry has encouraged migration from the northern part of Ghana to the southwestern region where the climate favours the growing of cocoa plants. The situation has led to the problem of encroaching originally forest and game reserves for the planting of cocoa trees. This region has been the highest cocoa producing region since 1985/86 crop season till date (Ghana Cocoa Board, 2017). This situation led to the involvement of child labour on cocoa farms which surfaced in the 2000s and become a worldwide issue for prominent business firms(Schrage & Ewing, 2005) According to Mighty Earth in 2017 that about 2.1m hectares and 820,000 hectares of forests were cleared in Cote d’Ivoire and Ghana respectively due to cocoa production over the decade.

Creating a city lifestyle in itself creates opportunities not only in that city but also for the countries from which it gets its raw materials.  To be able to maximize the benefits this endeavour brings, Countries in such situations should have had measures to regulate and monitor what happens in this industry. The lifestyle associated with chocolate in cities like Delft should create positive consequences for cities where the cocoa is grown in West Africa. The question is, must this lifestyle be at the expense of Forest and game reserves or innocent children drawn into child labour? After over a century of producing cocoa for this lifestyle living in the global north, should Ghana and Cote d’Ivoire be talking about Forest encroachment and child labour issues at this time?

‘NOT’ MADE IN HOLLAND

 

The tourist guide holding the flag high of his travel agency confidently describes the history of the brick-lined water canal through his rehearsed sermonic narratives in Delft, Netherlands. The flash and the clicks capture the linear canals in the frame, occasionally spotting the ‘Mallard’ and the ‘Ruddy’ Duck. These Mallards swim during summer and skate during winters. Countless videos can be found on the YouTube showing the mother duck waddling with her babies through the Delft houses reaching to the celebrated Dutch network of water canals. The ducks, an intrinsic part of the canal culture, are very much hard to miss. This blog looks at the ‘overseas’ ducks acclimatizing to the Dutch way of life and in turn making the Dutch citizens accustomed to them!

Duck, who tamed the citizens

A foreign student like me, who has been living in Delft for over six months, finds the Mallards homogenous to these brick-lined canals. These ducks not just survive on the bread scraps fed by the people, but they are also familiar with the timing of their masters arriving with food. These wild urbanised ducks have tamed the citizens which keeps up to their meal routines. A quick search of these species throws out information of how they prefer to live in swamps and thrive on slimy worms and plant material from the surface of the pond. The frozen period does not worry them, as they are well taken care of by the citizens themselves. Such is the relation! This ownership, a sense of belonging by the citizens towards the ducks is surprising, especially when one realises that these ducks are not even from Holland, well they came from North America!

Travelling Duck

Duck, who travelled

The Ruddy Duck was introduced into Europe from North America by humans, and the aggressive nature of this duck made it known as an invasive species. The Mallard Duck too travelled to a great extent. Some conjectural history suggests that this duck was first seen in Egypt, later, the Spaniards got it into Europe, and rest is history. The Romans relished the roasted duck meat and continued rearing them. Not until the 19th century did people realize that eggs taste well too!

Today the canals of the Netherlands are incomplete without ducks in it. This invasive species affect the endangered local ‘white-headed’ ducks. It is close to becoming extinct. But many biologists explain that getting extinct is part of nature as well. At present, it is difficult to imagine living with dinosaurs, great mammoths and the dodo. It is actually the static-ness in nature what one must be worried about. There is even a chance of this Ruddy Duck to form a hybrid with the white-headed duck to something that Jelle Reumer coined “Ruddy white-headed duck”. In coming years, we might have an evolved species of the multi-coloured duck waddling fiercely in the man-made canals, while the Dutch citizens feed them with organic wheat bread. This fascinating foreign bird may then again travel around the globe proliferating the wetlands of Sundarbans in Asia to the Amazon Basin in South America. Imagine, this avian Dutch hybrid may soon pursue the route that their colonizer fathers took! Interesting isn’t it?

Hybrid Ducks

 

Duck, the brand

While we galore at this marvellous species making its presence felt throughout the country, it is interesting to compare this object with the rest that is adding to Dutch imageries, namely – Tulips and the Delftware. The Tulips itself is the reason for many global travellers to visit the Netherlands, and the blue-white porcelain-ware is a preferred souvenir. And like the ducks, these two are also imported! Tulips came from Turkey and Delftware from China, which is now commodifying the global tourism of this country. After some more digging, I found out that the Netherlands does not officially have any national bird, but after a democratic bird poll, the favourite that was picked was (black-tailed) Godwit, which is found in the polders. Once more, a man-made habitat ‘constructing’ the environment for this bird, (and again), not originally from Holland!

Souvenirs

Duck, the language

This American duck does not portray as a misfit to the everyday spectators unless examined by a certain kind of biologist. Biologist, who is fighting against this globalisation wave, and trying to save the indigenous. Ironically, the masses that seem to have accepted the duck as a part of the culture also coined this phrase “vreemde eend in de bijt”, which literally means “a strange duck in the pack”. I suppose it is the adaptability of this foreign ‘strangeness’ that makes Dutch, Dutch, eventually making the Mallard and Ruddy Duck as their own.

i love strange ducks

Duck, the exotic object

K Piël from Amsterdam in his article which was a reply to a feature in the Trouw newspaper explained the Dutch attitude towards the ‘exotics’. The English exterminated the Ruddy Duck from the habitat in order to check the balance of its original species, whereas the Dutch urban ecologist Remco Slder feels we must accept the change in the eco-system along with modified species. He states, “We must accept man as a spread factor”. These contradictory attitudes coming from once-upon-a-time colonizers tells a lot of their current positionalities towards ‘nature’ (and how much the duck has situated itself in their day-to-day life!). The takeaway from this debate is what exactly is nature according to these two countries?

What constructs their imaginations?

Could the duck’s migration to the Netherlands have been avoided?

Is it unnatural for a foreign duck to adapt to manmade (dykes and canals) eco-system?

And then, is it strange for the citizens to celebrate its presence and habituate their life around it?

Evolution

While we ponder at these questions, one thing is sure that these ducks have definitely travelled a long way to become Dutch, and so has the Dutch citizen adapted towards the global culture brought in by these foreign birds!

Car tires as construction material and the emergence of Aedes aegipty in the city of Pemba

->Portuguese

This post is the result of fieldwork carried out in December 2017 in the city of Pemba, in the neighborhoods of Alto-Gingone, Cariacó and Natite. It describes how the socioeconomic characteristics of households, together with the climatic conditions of the city, can contribute to the proliferation of Aedes aegipty mosquitoes.

In recent years the province of Cabo Delgado has been receiving investments in several areas such as tourism and mining. These new investments have contributed to economic growth and improved living standards for some of the province’s population. Meanwhile, at the same pace as the economy of the province grows, the social problems in its capital the city of Pemba are growing too. In search of better living conditions, many families have migrated from the various districts of the province into Pemba, however, due to housing unavailability and lack of quality water and sanitation infrastructure, these families end up living in inadequate conditions. Most of them have to start building informal settlements. New migrants also face economic problems due to the high cost of living, as Pemba is considered the most expensive city in Mozambique.

The conventional building materials such as concrete, stone and adobe, are among the most expensive products marketed in the city. Many households can not afford o build a house with these materials. Alternatively households use available local materials to build their homes, materials such as clay, stones, bamboo and the inner part of car and truck tires.  The inner part of the tire is removed and cut into thin strips (see Fig. 1) which are used in the construction to join the bamboo and lift the walls  that are then coated with clay or cement. After having removed this part, the tires are discarded and they are used by the children as toys with which they play in the streets and in the backyards of the houses. When children get tired of playing the tires are left in the blocks’ backyards (see Fig. 2).

In some homes the tires are also used as locks for doors that give access to the yard as a way to prevent thieves from entering the yard and house. When they go to sleep, the families lean the tires on the doors, standing or lying down, so that whoever is outside the house can not open the door or, in case the person can, the tire makes enough noise to wake them up.

In rainy weeks, which are common in the city throughout the year, the tires dropped in the backyard can become breeding pools for Aedes aegipty . The female mosquitoes can lay their eggs inside the tires, which are filled with water after each rain. During my ethnography I  observed many tires in the streets and backyards of the neighborhoods, with not only water but also mosquito larvae inside (see Fig. 3).

Besides water storage containers located in and around households, tires are also contributing to the appearance and proliferation of the mosquito in this part of the country.

Uso de pneus como material de construção e surgimento de focos do Aedes Aegipty na cidade de Pemba

O presente texto é resultante de um trabalho de campo realizado em Dezembro de 2017, na cidade de Pemba, nos bairros de Alto-Gingone, Cariacó e Natite e descreve como a condição socioeconómica dos agregados, aliada às condições climáticas da cidade, pode contribuir para que estes estejam expostos à doenças transmitidas pelo Aedes Aegipty.

Nos últimos anos a província de Cabo Delgado tem vindo a receber investimentos em várias áreas como o turismo e a indústria extractiva, o que contribuiu para o crescimento económico e a melhoria de nível de vida da população daquela província. Entretanto ao mesmo ritmo que cresce a economia da província e, principalmente, da cidade capital, Pemba, agudizam-se os problemas sociais nesta cidade. A procura de melhores condições de vida, muitas famílias migram dos vários distritos da província para o centro da cidade entretanto, devido aos problemas de habitação e a falta de saneamento básico, estas famílias acabam por viver em condições pouco adequadas. Estes problemas agudizam-se devido ao alto custo de vida que a cidade tem, a cidade é considerada a cidade mais cara do país devido ao preço dos produtos que são relativamente maiores.

O material de construção convencional como cimento, pedra e areia, está entre os produtos mais caros comercializados na cidade. Muitos agregados não conseguem dinheiro suficiente para custear a construção de uma casa com esse material. Como alternativa os agregados utilizam o material local para construírem as suas casas, materiais como o barro, pedra, bambú e a parte interna de pneus de carros e camiões que são predominantes naquela cidade. A parte interna do pneu é retirada e cortada em tiras finas (ver Fig. 1) que são usadas na construção para unir o bambú e levantar as paredes e os muros que depois são revestidos por barro ou cimento. Depois de ser retirada esta parte, os pneus são descartados e passam a ser usados pelas crianças como brinquedos com os quais brincam pelas ruas e nos quintais das casas. Quando as crianças se cansam de brincar os pneus largados nos quintais das casas (ver Fig. 2).

Nalgumas casas os pneus são também usados como trancas para as portas que dão acesso ao quintal como forma de evita a entrada de ladrões no interior do quintal e da casa. Quando vão dormir, os agregados encostam os pneus as portas, de pé ou deitados, para que quem esteja do lado de fora da casa, não consiga abrir a porta ou para que, no caso de a pessoa conseguir, a porta faça um barulho suficiente para acordá-los.

Com a chuva e as altas temperaturas que se fazem sentir na cidade, os pneus largados no quintal podem virar criadouros do Aedes Aegipty. A fêmea do mosquito pode depositar os seus ovos no interior do pneu, que depois das chuvas fica cheio de água, pode reproduzir-se e posteriormente infectar os residentes da casa ou do bairro pela dengue através de picadas. Durante a recolha de dados foi possível ver vários pneus nas ruas e quintais dos bairros com água e larvas no seu interior (ver Fig. 3).

No caso da idade de Pemba é necessário que se tenha uma atenção redobrada para a questão do uso de pneus pois estes também podem ser fundamentais para o surgimento e o aumento de focos do Aedes Aegipty, o que pode aumentar e agravar os casos de Dengue naquele ponto do País.

Social and ecological meanings of water-containers

->Portuguese

On the 6th of November 2017 I embarked in a journey to the city of Maputo, Mozambique. I travelled to this emblematic city located in a beautiful bay of the Indian Ocean with the intention of understanding water-storage practices in the city, and researching whether these relate to the re-surgence of Aedes mosquitoes in Mozambique. Since the moment I decided this was going to be my MSc research topic, I read everything I could on the city colonisation, urbanisation, and water-services context. Furthermore, I was also trying to correlate these contexts with certain ideas I had on aquatic habitats for mosquitoes. As much as my head could compile the published information and draw images from the many historical documents of the city, nothing prepared me to the experience of the city, being there, walking, getting lost, talking to people, living the city from a first-hand experience.

Methodologically, I knew that my thesis would have to consider the social connotations of water storage, alongside the aquatic habitat assessment of water-containers. I am a biologist, so from my ideas of what a habitat is, how it establishes, and the characteristics it may portray I was ready to evaluate these characteristics in the city. However, as I walked the city and started talking to people, communities, researchers, and health-specialists from Maputo, I found that exploring Aedes aegypti’s habitats in a city like Maputo was going to challenge my preconceived ideas of what a habitat is, and how nature occurs in rich social contexts.

Due to water shortages and service challenges faced by small water providers and by the National Water and Sanitation Company FIPAG, intermittence is the common rule, hence water-storage is a collective practice in Maputo. Residents of the city have water readily available in multiple ways, whether it is through direct connections to the water utility, independent water providers, via water-tanks, resale, or communal kiosks. However, as I zoomed in to some particular contexts and neighbourhoods of the city, I found that water availability is experienced and materialised differently. For example, large water tanks found in formal spaces, like Polana cimento, allows residents in these areas to store water in bulk and accumulate it in perpetuity. Conversely, smaller water buckets in informal places like Chamanculo, make water less available throughout the day for the residents of this neighbourhood. This provides an interesting outlook on how formality and informality in the urbanisation process of a city like Maputo, translates to different daily routines of water-storage.

Experiences and materialisation of water service intermittence concur with emergence of aquatic habitats for mosquitoes like Aedes aegypti. While water intermittence determines water-storage practices, water quality parameters like temperature, pH, electrical conductivity, organic material, and light intensity come into place to complicate the water-container. Stored water rapidly transforms into an aquatic habitat not only for mosquitoes, but to a myriad of microorganisms that are harmful for human health.

Significados sociais e ecológicos de recipientes de água

No dia 6 de Novembro de 2017, embarquei numa viagem para a cidade de Maputo, Moçambique. Eu viajei para esta cidade emblemática localizada em uma bela baía do Oceano Índico com a intenção de entender as práticas de armazenamento de água na cidade, e pesquisando se estas se relacionam com a ressurgência de mosquitos Aedes em Moçambique. Desde o momento em que decidi que este seria meu tópico de pesquisa de mestrado, fiz a revisão de artigos sobre a colonização da cidade, a urbanização e o contexto dos serviços de água. Além disso, eu também estava tentando correlacionar esses contextos com certas idéias que tinha sobre habitats aquáticos para mosquitos. Por mais que minha cabeça pudesse compilar as informações publicadas e desenhar imagens dos muitos documentos históricos da cidade, nada me preparou para a experiência da cidade, estando lá, andando, me perdendo, conversando com as pessoas, vivendo a cidade de uma experiência pessoal.

Metodologicamente, eu sabia que minha tese teria que considerar as conotações sociais do armazenamento de água, juntamente com a avaliação do habitat aquático de recipientes de água. Sou bióloga de formação e, por isso, pelas minhas ideias sobre o que é um habitat, como ele se estabelece e as características que pode apresentar, senti-me pronta para avaliar essas características na cidade. No entanto, enquanto caminhava pela cidade e comecei a falar com pessoas, comunidades, investigadores e especialistas de saúde de Maputo, descobri que explorar os habitats do Aedes aegypti numa cidade como Maputo iria desafiar as minhas ideias preconcebidas sobre o que é um habitat, e como a natureza ocorre em contextos sociais ricos.

Devido à escassez de água e aos desafios de serviço enfrentados pelos pequenos fornecedores de água e pelo Fundo de Investimento e Património do Abastecimento de Água FIPAG, a intermitência é a regra comum, pelo que o armazenamento de água é uma prática colectiva em Maputo. Os moradores da cidade têm água prontamente disponível de várias maneiras, seja por meio de conexões diretas com a concessionária de água, fornecedores independentes de água, via tanques de água, revenda ou quiosques comunitários. No entanto, à medida que ampliava alguns contextos e bairros particulares da cidade, descobri que a disponibilidade de água é experimentada e se materializa de maneira diferente. Por exemplo, grandes tanques de água encontrados em espaços formais, como no bairro da Polana cimento, permitem que os moradores dessas áreas armazenem água a granel e a acumulem por muito tempo. Por outro lado, pequenos baldes de água em lugares informais como o bairro de Chamanculo, tornam a água menos disponível durante o dia para os moradores deste bairro. Isto fornece uma perspectiva interessante de como a formalidade e a informalidade no processo de urbanização de uma cidade como Maputo, se traduzem em diferentes rotinas diárias de armazenamento de água.

Experiências e materialização da intermitência do serviço de água coincidem com o surgimento de habitats aquáticos para mosquitos como o Aedes aegypti. Enquanto a intermitência da água determina as práticas de armazenamento de água, os parâmetros de qualidade da água, como temperatura, pH, condutividade elétrica, material orgânico e intensidade de luz, são utilizados para complicar o recipiente de água. A água armazenada se transforma rapidamente em um habitat aquático não apenas para os mosquitos, mas para uma miríade de microrganismos prejudiciais à saúde humana.

Who is vulnerable to contracting dengue in the neighborhood of Cariacó, city of Pemba?

->Portuguese
Gathering with male community members. Alto-Gingone, November 2017

During the discussions held by the research team of the project, it was suspected that women would be vulnerable to Aedes aegypti mosquitoes. This because these mosquitoes frequently bite inside households and during morning hours and (we thought) many women stay home during the day. However, after traveling to Pemba and conducting house to house ethnographic work in the low-income neighborhood of Cariacó, one of the neighborhoods that was most affected by the dengue epidemic, I was struck by the number of young men who were at home during the day. Young men stayed home during the mornings and afternoons hanging around the house, in the living room watching television or in the small porches sitting on top of the beds (beds made of sisal and wood). These young spent their days chatting and playing on their high-end mobile phones.

On the basis of a conversations with some of these young men, it was possible to know that a large part of the youngsters finished the average level of general education and could not find a formal job. Some of the youngsters engage in temporary jobs that provide immediate cash payments, accompanying tourists in the city and showing them the main sights, especially the beaches. In addition to these young men I also observed the presence of some children who gave up school. In conversations some of them justified their decision arguing that “studying is very difficult”. I also noticed the presence of elderly women sitting in the living rooms or on the porches. Based on these observations, it was possible to reflect on the difference between the ideas we made before going to the field and what was really going on the ground. While most women were outside working, young men were hanging out around the house.

Quem é vulnerável de contrair dengue no bairro de Cariacó, cidade de Pemba?

Durante as discussões da equipe de pesquisa do projecto: “Dengue, Água e Agregados Familiares” suspeitou-se que as mulheres estariam vulneráveis ao mosquito causador da dengue, porque grande parte de mulheres ficam em casa durante o dia. A partir de observações realizadas nos agregados familiares, no bairro de Cariacó, em Pemba, durante o period entre 07-13 de Dezembro de 2017, chamou-me a atenção a quantidade de jovens de sexo masculino que se encontravam em casa durante o dia, na sala de estar a assistir televisão ou nos pequenos alpendres sentados por cima de quitantas (camas construídas de fios de sisal e madeira). Estes jovem mexiam em seus telemóveis que curiosamente são de alta qualidade.

Com base numa rapida conversa com alguns desses jovens foi possivel saber que grande parte dos jovens terminou o nível médio do ensino geral e não conseguiu arranjar emprego formal. Alguns dos jovens fazem biscatos (trabalhos temporários que dão dinheiro imediato) quando aparecem turistas na cidade que os acompanham para mostrar os locais turísticos da cidade de Pemba, especialmente as praias. Para além desses jovens também observei a presença de algumas crianças que desistiram de estudar, que na conversa com algumas delas justificaram que estudar é difícil. Tambem observei a presença de mulheres idosas sentadas na sala de estar ou entao na varanda. Com base nessas observações foi possível reflectir sobre a diferença que existe entre as ideias que elaboramos antes de ir ao campo e o que realmente ocorre no terreno.

Chasing the mosquito

->Portuguese

Aedes aegypti, water, and households: chasing the mosquitos in the Urban South

In 2014 and 2015 various outbreaks of dengue were reported in Mozambique. In countries of Latin America and the Caribbean, such as Colombia, there have also been outbreaks of dengue, zika and chikungunya. High percentages of Aedes aegypti, the mosquito that most effectively transmits these diseases, were found in cities such as Pemba, Maputo, Barranquilla, and Buenaventura. Dengue, zika and chikungunya, and their transmission vector, mosquito Aedes aegypti are tied to water as this mosquito lays eggs in stored water in or around households. After they breed they do not always parade through the city like other mosquitos, but they hide inside households, behind doors and corners (Higa et al., 2015).

Besides being tied to water, Aedes aegypti are also tied to climate change. Studies have warned of the possibility that climate change might increase the likelihood of diseases spread by insects in new areas , as temperature can affect the distribution of the mosquito and the effectiveness of the virus transmission and rainfall can increase surface water (providing breeding sites for more mosquitos) (Hunter, 2003). The pattern of dengue’s spread has changed through the years, as the mosquito has adapted to new processes of economic, political, and social change (Higa et al., 2015; Nading, 2012, 2014).

By staying close to humans and adapting its biting periods to those of human activities, female mosquitoes can develop and lay eggs in aquatic habitats easily found in cities (Beaty et al., 2016; Gubler, 2011). Stagnant or stored water buckets, tanks, drums, cisterns, flower vases, pools, tires, and other man-made containers provide the needed cultivation habitat, where larvae will develop shortly into adult versions of the mosquito. This project uses an ethnographic approach to study households, water supply availability, intermittence and distribution, and document politics and everyday community strategies to obtain and store water. It focuses on the interdependence between intermittent water supply, deficient solid waste collection, and the Aedes aegypti. It also takes into account the different legacies left by civil wars and rural crises on processes of unequal urbanization. It doing so, the project engages with multiple actors: local and national regulators and state officials, water services providers, non-governmental organizations, and the different communities in the cities’ neighbourhoods.

Aedes aegypti, água e Agregados familiares: Perseguindo os mosquitos no Sul Urbano

Em 2014 e 2015, vários surtos de dengue foram relatados em Moçambique. Nos países da América Latina e do Caribe, como a Colômbia, também houve surtos de dengue, zika e chikungunya. As altas percentagens de Aedes aegypti, o mosquito que transmite mais eficazmente essas doenças, foram encontradas em cidades como Pemba, Maputo, Barranquilla e Buenaventura.
Dengue, zika e chikungunya, e seu vetor de transmissão, o mosquito Aedes aegypti estão associados à água, pois este mosquito coloca ovos em água armazenada dentro dos agregados familiares. Depois de porem ovos, os mosquitos nem sempre passam pela cidade como outros mosquitos, mas se escondem dentro dos agregados familiares, atrás de portas e cantos (Higa et al., 2015). Além de estarem associados à água, Aedes aegypti também está ligada à mudança climática. Estudos alertaram sobre a possibilidade de que as mudanças climáticas possam aumentar a probabilidade de doenças transmitidas por insetos em novas áreas, dado que a temperatura pode afetar a distribuição do mosquito e a eficácia da transmissão do vírus e as chuvas podem aumentar a água superficial (criando locais de reprodução para mais mosquitos) (Hunter, 2003).

O padrão de disseminação da dengue mudou ao longo dos anos, dado que o mosquito se adaptou a novos processos de mudança econômica, política e social (Higa et al., 2015; Nading, 2012, 2014). Ao ficar perto dos seres humanos e adaptar-se aos seus períodos de mordida às atividades humanas, os mosquitos femininos podem desenvolver e colocar ovos em habitats aquáticos facilmente encontrados nas cidades (Beaty et al., 2016; Gubler, 2011). A água estagnada, os baldes de água armazenados, tanques, tambores, cisternas, vasos de flores, piscinas, pneus e outros recipientes artificiais fornecem o habitat de reprodução necessária, onde as larvas se desenvolverão em pouco tempo em versões adultas do mosquito.

Este projeto usa uma abordagem etnográfica para estudar os agregados familiares, a disponibilidade de água, intermitência e distribuição e documentar políticas e estratégias comunitárias diárias para obter e armazenar água. O projecto se concentra na interdependência entre o abastecimento de água intermitente, a coleta de resíduos sólidos e o Aedes aegypti. O projecto também leva em conta os diferentes legados deixados pelas guerras civis e crises rurais em processos de urbanização desigual. Ao fazê-lo, o projeto envolve múltiplos atores: reguladores locais e nacionais e funcionários do Estado, provedores de serviços de água, organizações não-governamentais e as diferentes comunidades nos bairros das cidades.
