Abstract

Many cities in the world are adopting a free paying system to enable them meet up with cost of solid waste management (SWM). The effectiveness of this system is influence by the willingness to pay (WTP) by the community and their level of awareness of environmental issues. This study sought to determine the WTP and the level of awareness of the inhabitants of Mamfe Town, Cameroon for improved SWM. In carrying out the study, 371 households were sampled in a randomly through interviews, guided questionnaires, followed by Statistical analysis by multiple regression analysis in SPSS 21.0 and contingent valuation method (CVM) to identify the determinants of WTP values. The results showed that Mamfe residents had relatively good environmental awareness. With regard to Mamfe environmental quality, 51.5% expressed their satisfactions on current situation. About 74.5% thought that the water pollution caused by poor waste disposal in Mamfe was more serious than other two environmental pollutions. The survey data revealed a positive attitude towards source separation in Mamfe. 73.1% were willing to sort solid waste at home, if the government required them to do so. In addition, on the important of improvement of the solid waste recycling in Mamfe, “enhancing residents’ environmental awareness was considered as the most effective methods, accounting for about 68.6%. Regarding the WTP bid questions, most of our respondent (85.1%), show a positive attitude towards WTP for an improved SWM in Mamfe. Probit and Tobit regression analysis reveal factors such as age, employment type, household type and income of the respondent have a significant relationship with willingness to pay at (p<0.05). The monthly mean WTP was 1000FRS per household and annual WTP was approximately 60 million FRS for all of Mamfe town. The results can be useful for understanding the residents’ attitudes and WTP for solid waste disposal, for the policymakers and managers, and used to promote the recycling of solid waste in Mamfe.

CHAPTER ONE

INTRODUCTION

1.1 Background to The Study

Urbanization process and rapid population growth in many cities and towns in the world have been reported as one of the reasons for the increase in solid waste (SW) generation in developing countries (Ali et al., 2012). According to Hagoset al. (2012), the rapid expansion and diversification of socio-economic activities in these urban and fast growing towns have also contributed to a lot of environmental problems including poor solid waste disposal, poor liquid waste management, and air pollution.

Global solid waste generation in 2012, according to United Nations Environment Programme (UNEP, 2012), was 1.3 billion tones. This amount is estimated to rise to 2.2 billion tons/year by 2025, with much of the increase as a result of rapidly growing cities especially in developing countries. The UNEP indicates that low income countries are expected to generate about 213 million tons of solid waste a day with the population rising to about 676 million by 2025. Lower middle income countries are also projected to generate about 956 million tons of solid waste per day while their population is projected to reach 2.08 billion by 2025 (UNEP, 2012). More so, waste generation is estimated to reach 360 million tons/day by 2025 in upper middle income countries with expected population of 619 million. For high income nations however, waste generation a day by 2025 will be about 686 million tones at a population of 912 million (UNEP, 2012).

Inadequate and ineffective management of wastes worldwide leads to generating a lot of human and environmental problems like ozone layer depletion, acidic rains, greenhouse effects as well as land and epidemic diseases (Ali et al., 2012). Across the African continent, the rate of urbanization is around 3.5% and the rate is expected to rise in the future (UNESCO, 2009). This high rate of unplanned urbanization has a significant negative effects on the environment such as pollution and degradation. Cameroon as one of developing countries with little technological advancement and financially constrained, it experiences severe impacts of poor waste management. According to Kasim and Ali, (2006), the problems come from the little public awareness about the nature and impacts of these solid wastes they produce.

Solid waste management (SWM) is very crucial to households living in rural and urban areas because waste has reported to be directly linked to the development of human activities in terms of technologies and social aspects (Awuyoet al., 2013). Waste are by-products generated as a results of human activities. Since the waste materials produced cannot be used for other things, they need to be disposed of effectively.

In the past, SWM is the responsibility of the government finance by general revenue. However, in recent years, partly as a result of austerity and structural adjustment policies and pressures from multilateral financial institutions, and partly as a result of pressures to limit taxes, various governments have increasingly focused on identifying specific revenue sources for waste management (Longeet al., 2009).

 

1.2 General Context Of Waste Management In Cameroon

In Cameroon, waste management has developed at a gradual pace over the past decades (Din-Louis, 2015). Solid waste management in the past did not receive appropriate public and municipal attention. It is common to see mountains and heaps of refuse in villages and towns. These heaps of waste materials contains toxic substance that are harmful to the human health when come in contact with. The waste materials that usually is risky to the population is sometimes burnt, emitting smoke in to the atmosphere. Meanwhile, heaps of waste constitute enormous wealth that could be recovered, recycled or transformed into economic goods. Waste runoff from waste usually pollute small water bodies, such as streams and springs that provides drinking water for the population.

Problems presently encountered in solid waste management emanate from inadequacies of public service provisions. For example the collection of solid household waste is the responsibility of Municipal authorities, but this responsibility is sometimes limited by technical and financial constraint back by corruption, lack of transparency and accountability (Baboucar, 2015).

Even when these Councils dispose the necessary means to carry out these activities, public collaboration in this domain is sometimes very wanting. The Cameroon private sector HYSACAM, is not yet motivated in these activities and therefore considered environmental protection, a problem of the government to be face along with the waste generators.

These types of residential areas are in most case illegal and hardly benefits from Cameroon Assistance in waste management. Even when they are legal poor municipalities like the Mamfe Rural council do not have the means to put in place an appropriate waste management schemes. Such types of neighborhoods are considered undesirable because they are muddy, constructed in valleys, consequently, even when there is a means to collect waste, they are often left aside because of in accessibility. The poor who live in these types of quarters usually have no choice but to live in harmony with their dirty environment.

 

1.3  Statement of The Problems

Waste is an unavoidable consequence of the consumption and production activities of a society. Proper handling of waste is becoming a serious problem of cities all over the world especially in developing countries where financial and technical scarcity is very serious.

Environmental problems in Cameroon are results of many contributing factors. These include unplanned construction of houses, uncontrolled location of industries and factories, migration of people almost from all corners of the country, and most importantly, of course, is the inability of the government to find efficient ways to manage and finance environment needs of the people.

In this regard, various researchers in different parts of the world conducted their study to identify and analyze the determinants of households’ contribution or WTP for improved solid waste management in their respective countries. Some of the most important works areMuradet al.(2006), Afrozet al. (2009), Banga et al. (2011), Ali et al. (2012), Hagoset al. (2012), Song et al. (2012),  Subhanet al. (2014), Kweteyet al. (2014) and Nkansahet al. (2015).

However, in Cameroon no studies on the demand side of waste management have been carried out that look at household’s WTP for an improved SWM. Most studies carried out, for example, Manga et al (2008) focus on waste management policy perspectives, Mbenget al. (2012) and Tambe et al. (2012) examine waste characteristics in Limbe and Kumba respectively, Din-Louis (2015) look at household waste practices in Limbe and Baboucar (2015) examine community perception of MSW in Buea.

Mamfe is one of the fastest growing town in Cameroon demographically and economically. The production of solid waste in Mamfe town has increase in amount and as well in composition, which ultimately creates a critical issue to waste authorities in Mamfe. According to studies conducted by Arrey (2005), an average person in the town produces 280gramms of waste per day, with no collection and disposal facilities set up in the town for proper waste management. This is likely to cause serious public health problems through possible eruption of diseases, including often fatal water-borne diseases, such as cholera, diarrhea and dysentery, as householders dump their waste on streams, rivers, road sides that eventually lead to health diseases and thus making the environment aesthetically unfriendly.

Despite the critical problem on SWM service, little has been done to examine the households’ WTP for improved SWM services in Mamfe Town. There is a lack of information on household WTP for the services provided. Therefore, this study examined the households’ WTP for improved SWM services in Mamfe town, by examining the extent of households’ participation, their attitudes towards improve SWM action and the factors influencing households’ WTP and the MWTP value. The output of this study will provide useful recommendations to policy makers and other stakeholders to improve SWM system in Mamfe Town and the country at large.

 

1.4  Rationale of The Study

Establishing effective Council SWM services is an important role in protecting the environment to improve sanitary and public health.  Mamfe Town is experiencing rapid urbanization and increasing urban population due to territorial expansion, increased rural-urban migration rate and the increasing per capita incomes in the region. This has led to the increased production of solid waste in the town.

The production has increased rapidly in terms of waste amount as well as composition, which ultimately creates a critical issue for waste management authority. As one of the strategies to improve sanitary services in the town, the Mamfe Town Council decided to contract a private firm which would collects fees for SWM service from the community. There is a presence of uncontrolled wastes on the streets, including Market Centre’s, and homes.

Therefore, the key question here is how much household residents are willing to pay for efficient and cost-effective delivery of SWM services to their households. The aim of this study is therefore to examine the extent of households’ participation, their attitudes towards SWM actions and factors influencing households’ WTP and the MWTP value; and to suggest mechanisms for improving the participation of communities in SWM. The output of this study also provides useful recommendations for future studies to other regions in the country or to other national contexts of a similar set-up to test and extend the generalizations of the findings.
