30 Years of Macroeconomic Effects in Zambia-VECM, ARDL & IRF Approaches

Purpose: This study examines the impact of selected time series macroeconomic variables on Zambia’s economic progress for thirty (30) years (1992 to 2022) Methodology: The study employs the autoregressive distributed lag (ARDL), vector error correction models (VECMs) and the impulse response functions (IRFs) approaches. Findings: The VECM regression estimates indicate that in the long-run, ceteris paribus, a 1% increase in inflation and population growth rates cause a significant positive impact on economic progress of 0.36% and 0.68 % respectively whereas the total public debt stock causes decrease in economic growth of 0.45%. The ARDL long-run regression estimates indicate that ceteris paribus, a 1% increase in inflation and public debt significantly reduces real GDP by 0.2% and 0.03%, respectively, but a 1% increase in population growth rate increases real GDP by 23.11%. The IRF estimates show that a negative shock to the real GDP causes a mildly negative effect on the inflation rate, causes a significant positive increase in the population growth rate, which dissipates after 9.5 years and causes a significant positive increase in public debt, which dissipates after 10 years. Unique Contribution to Theory, Policy and Practice: Therefore, the study recommends that the Zambian government should prioritize repayment of the outstanding public debt by bringing down the debt-to-GDP ratio to sustainable levels, adhering to prudent public financial management and continuing to grow the domestic revenue base. The policies to promote population growth should be pursued cautiously because rapid population growth rates could erode the future economic growth prospects of Zambia.

STRATEGI PEMERINTAH DALAM IMPLEMENTASI PERDA NOMOR 6 TAHUN 2015 TENTANG PENGELOLAANSAMPAH DI KABUPATEN BUNGO(Studi di Dinas Lingkungan Hidup Kabupaten Bungo)

The research location was carried out at the Bungo Regency Environmental Service. This research lasted for one month, namely August 2019. The research aims to determine the implementation of regional regulations regarding waste management in Bungo Regency based on Regional Regulation Number 6 of 2015 and to determine the obstacles in implementing Regional Regulation Number 6 of 2015 concerning waste management in Bungo Regency. This research uses a qualitative method where this research uses descriptive data in the form of written or spoken words from people and observable behavior.The results of the research show that the Environmental Service Strategy in Implementing Regional Regulation Number 6 of 2015 concerning Waste Management in Bungo Regency, which is described as a program for developing waste management performance as program implementers, is a program that was born to answer waste problems and optimize cleaning services and improve environmental cleanliness. and settlements to public spaces in Bungo Regency. In the explanation of the strategy of the Environmental Service in implementing the regional regulation policy, the program for developing the performance of cleanliness management for communication developed by the Environmental Service of Bungo Regency has not been implemented optimally. The obstacle in achieving the implementation of this policy is the rapid rate of population growth in Bungo Regency so that Waste production also increases. Low public awareness is one of the problems faced in implementing this strategic policy related to cleanliness management and the community's obligations towards the environment, namely the lack of public awareness in practice of always throwing rubbish not in the places provided by the Environmental Service. Furthermore, the obstacle in the Environmental Service's strategy in implementing the regional regulation is the inadequate facilities and infrastructure for cleaning management and the next obstacle is the lack of budget owned by the Bungo Regency Environmental Service so that implementing strategic policies is not yet optimal.

The right banker plant for the right application: Comparison of three candidates for aphid biocontrol, barley (Hordeum vulgare L.), corn (Zea mays L.), and finger millet (Eleusine coracana (L.) Gaertn).

In temperate regions, aphid biological control in greenhouses is mostly achieved by the regular release of biocontrol agents. Due to the rapid growth rate of the aphid population, biocontrol agents must be released frequently in order to be present before pest outbreaks and to act rapidly to prevent exceeding the economic threshold. Banker plants reduce these numerous releases by providing natural enemies with a high-quality environment to develop and reproduce. Optimally, banker plants should be easy to produce, resistant to environmental conditions, provide a large amount of suitable banker prey in order to produce a high number of biocontrol agents, and resist the herbivory pressure of the banker prey. The present study aimed to compare the value of three banker plant candidates of the Poaceae family under laboratory and greenhouse conditions: barley (Hordeum vulgare L.), finger millet (Eleusine coracana (L.) Gaertn), and corn (Zea mays L.). Our results show that the three plants were suitable for different contexts. Finger millet yielded the biggest fresh plant biomass, supported the highest load of banker prey, and resisted aphid feeding longer than the other plant species. Corn was the cheapest to produce, and barley was the fastest to grow. Overall, finger millet could be more fitted for long crop cycles, pests with rapid population growth rates, and voracious or fast-reproducing biocontrol agents. Meanwhile, barley and corn may be better suited for rapid crop cycles, pests with slow population growth rates, and biocontrol agents that are not too voracious or have low reproductive rates. © 2024 The Authors.

EXPLORING THE PARADOX OF POPULATION GROWTH AND FOOD RESOURCES IN PUNJAB – PAKISTAN: REASSESSMENT IN THE LIGHT OF MALTHUSIAN THEORY

The correlation between population growth and economic development has been a persistent subject of inquiry among demographers and development economists. While some academics assert that population growth impedes economic development, others contend that it is advantageous due to the expansion of the workforce. Thomas Robert Malthus posited that population increases surpass the growth of food resources, resulting in food shortages and a diminished standard of living. The Neo-Malthusian theory advocates for the implementation of population control measures. This research delves into the connection between population growth and economic development in Pakistan, examining the validity of Malthus' assumptions. As the sixth most populous country with limited land area, Pakistan's largest unit, Punjab, holds a substantial portion of its population and food production. Through the analysis of data spanning from 1971 to 2017, despite experiencing a rapid population growth rate of 2.4% in 2017, a positive association between population growth and food resources was identified throughout the studied period.

Native amphibian toxin reduces invasive crayfish feeding with potential benefits to stream biodiversity

BackgroundBiodiversity is generally reduced when non-native species invade an ecosystem. Invasive crayfish, Procambarus clarkii, populate California freshwater streams, and in the Santa Monica Mountains (Los Angeles, USA), their introduction has led to trophic cascades due to omnivorous feeding behavior and a rapid rate of population growth. The native California newt, Taricha torosa, possesses a neurotoxin, tetrodotoxin (TTX), that affects freshwater animal behavior. Given P. clarkii has a limited evolutionary history with TTX, we hypothesized that TTX may affect crayfish feeding behaviors. To determine if TTX affects P. clarkii behavior, we measured cumulative movement and various feeding behaviors of P. clarkii exposed to (i) waterborne, ecologically realistic concentrations of TTX (~ 3.0 × 10− 8 moles/L), (ii) an anuran chemical cue to account for intraguild cues, or (iii) a T. torosa chemical cue with quantitated TTX in it (~ 6.2 × 10− 8 moles/L).ResultsWe found that the presence of TTX in any form significantly reduced crayfish movement and decreased the amount of food consumed over time. Crayfish responses to the anuran treatment did not significantly differ from controls.ConclusionOur laboratory results show that naturally occurring neurotoxin from native California newts limits invasive crayfish foraging and feeding rates, which may play a role in preserving local stream ecosystems by limiting invasive crayfish behaviors that are detrimental to biodiversity.

Assessment of solid waste management in Ota, Ogun State, Nigeria

The rapid rate of population growth and urbanization has impacted the management of municipal solid wastes (MSW) and is increasingly becoming a major concern in many cities in developing countries. Insufficient area coverage for wastes collection, processing system, and unsuitable disposal all appear to be the causal factors. This paper discussed the current situation of solid waste management in Ota municipality as well as the challenges and associated problems. Structured questionnaires, interviews and on-site observations were used for data generation, and subsequently analyzed using descriptive statistics. Results indicated that 28.6% of the respondents incinerate their wastes, while 27.6% of the respondents dispose theirs to public waste bins. About 11.4% deposit their wastes by the road side, while 6.4% dump their wastes in drainages and water bodies. Most respondents incinerate their wastes which would impact negatively on the ozone layer. Results also indicated that 54.3% of the respondents have their wastes disposed regularly, while 66% do not sort their wastes which make them difficult to manage. The city's single dump site was visited in order to have a better understanding of the existing solid waste management measures in place. Other illegal waste dumps in the town were also visited. In order to address the difficulties of solid waste management in the municipality, it is recommended that the state government engage additional Private Service Provider (PSP) operatives to assist with waste collection and transportation, provide suitable facilities, machinery, and equipment, and launch a public awareness campaign

Rapid population growth and high management costs have created a narrow window for control of introduced hippos in Colombia

The introduction of hippos into the wild in Colombia has been marked by their rapid population growth and widespread dispersal on the landscape, high financial costs of management, and conflicting social perspectives on their management and fate. Here we use population projection models to investigate the effectiveness and cost of management options under consideration for controlling introduced hippos. We estimate there are 91 hippos in the middle Magdalena River basin, Colombia, and the hippo population is growing at an estimated rate of 9.6% per year. At this rate, there will be 230 hippos by 2032 and over 1,000 by 2050. Applying the population control methods currently under consideration will cost at least 1–2 million USD to sufficiently decrease hippo population growth to achieve long-term removal, and depending on the management strategy selected, there may still be hippos on the landscape for 50–100 years. Delaying management actions for a single decade will increase minimum costs by a factor of 2.5, and some methods may become infeasible. Our approach illustrates the trade-offs inherent between cost and effort in managing introduced species, as well as the importance of acting quickly, especially when dealing with species with rapid population growth rates and potential for significant ecological and social impacts.

Are indicators useful for measuring and supporting the sustainability of forest use? A Zambian case study

Widespread dependence of rural communities on forest products is recognised, however, existing data on forest product use are limited and may not reflect current trends, as dependence patterns change over time. In the context of rapid deforestation, high levels of poverty, and associated reliance on natural resources such as forest products to support livelihoods, it is important to understand the current role of forests for supporting livelihoods so that these can be incorporated into policy and forest management efforts. Effective policies should go a step further and consider attitudes and behaviours of forest product users and attempt to understand linkages between behaviour and forest use. Being able to measure the sustainability of forest use (i.e. the impact of behaviours on the provisioning forest ecosystem) by using a composite indicator approach, is useful if we are to understand the potential impact of changes in behaviour or use patterns and if we hope to make changes that will result in more sustainable use. Here, we assess forest dependence using household interview data collected from 574 households in rural North-Western Zambia. Forest use data were recorded, which we used to inform the development of a forest use sustainability indicator, as were attitudes to forests and forest management, in an area where livelihoods depend on forest resources, with the backdrop of rapid national population growth and deforestation rates. While forest dependence among households was high (97% of households used forest products) and attitudes were generally pro-forest conservation, actual forest use (behaviour) showed signs of being unsustainable, based on the sustainability indicator used to measure forest use sustainability. By using an indicator approach to measure the sustainability of forest use at a household level, we were able to calculate projections of future sustainability based on theoretical future changes in harvesting practices. Local level quantifications of sustainability using standardised tools such as composite indicators could contribute to greater transparency in the process of analysing factors affecting sustainability and the development of appropriate, inclusive, and situation-specific policy to address the sustainability of forest use.

Couple Asymmetries and Modern Contraceptive Use among Young Married Women in Nigeria

Nigeria is faced with high fertility, maternal and child mortality, and a rapid population growth rate. The uptake of modern methods of contraception is crucial to reduce the high fertility rate, halt population growth, lessen child mortality, and enhance maternal health. This study assessed partners' socio-economic and demographic asymmetries as barriers to modern contraceptive use among young married women in Nigeria. This study used data for 5,772 young married women aged 15-34 years from the Nigerian Demographic and Health Survey 2018. Frequency distributions and binomial logistic regression were carried out using STATA v12. Findings show that 20.4% of young married women use modern contraceptives. Respondents whose partners desire more children were less likely to use modern contraceptives (AOR= 0.712, CI 0.603-0.840). Also, contraceptive use is less likely when the respondent's partner is more educated than the respondent compared to if both have the same level of education (AOR= 0.721, CI 0.607-0.857). Differences in partners' fertility desires and educational status are associated with the use of modern contraceptives among married women aged 15-34 years in Nigeria.

Resource mobilization for tetanus vaccination in Vietnam: Uptake, demand and willingness to pay among women of reproductive age.

Tetanus vaccine coverage in Vietnam has been declining in recent years due to a rapid population growth rate, shrinking budget, and inefficient resource mobilization strategy. This study examined the uptake, demand, and willingness to pay (WTP) for tetanus vaccines in Vietnamese women of reproductive age as well as determined associated factors and assessed the feasibility of the long-term tetanus vaccine resource mobilization scheme. Cross-sectional data were obtained on 807 women of childbearing age in Hanoi, Vietnam in 2016. Tetanus vaccine uptake, demand, and willingness to pay were collected by using a structured questionnaire. Multivariable logistic and interval regression models were used to examine associated factors with vaccine uptake, demand, and WTP. Of 807 participants, 42.4 and 64.8% had sufficient tetanus vaccination (i.e., received at least three doses of vaccine) and were willing to pay for tetanus vaccination. The mean amount of WTP for one dose of tetanus was US$ 7.3 (95% CI = 6.7-7.9). Having children or being aware that the tetanus vaccine was free-of-charge were negatively associated with WTP for tetanus vaccine. Having a high school education, living in a rural area, and not being aware of vaccine prices or being aware that vaccines were provided freely reduced the amount of WTP. WTP increased among women receiving information from friends and relatives. Despite of exemption from the tetanus vaccination programs, this study indicated a low tetanus vaccination coverage and a moderate degree of WTP for tetanus vaccine among Vietnamese women of childbearing age. Target-specific educational and financial support interventions, along with efforts to reduce vaccination costs are critical to improving the vaccine uptake, demand, and WTP for tetanus immunization among women.

The Relationship in Mothers Between Knowledge Level and Compliance in the Use of Birth Control Pills

The Indonesian Government has used family planning in an effort to suppress the rate of population growth in Indonesia which is considered very fast. A rapid rate of population growth can increase the burden of national development and reduce the quality of family life. Therefore, the Government has attempted to reduce the total fertility rate in Indonesia. The impact of non-compliance in taking birth control pills can cause the hormones contained in the pill to not work optimally, and therefore pregnancy may not be prevented. Non-adherence often occurs in long-term drug consumption, including birth control pills. Compliance in taking birth control pills is a behavior related to a person’s level of knowledge about how to correctly use them. The purpose of this study was to determine the relationship between the level of knowledge and adherence to the use of birth control pills in women of childbearing age in Beru Village, Blitar Regency. Descriptive methods were used with a cross-sectional design. Data were collected using a knowledge questionnaire and a compliance questionnaire filled out by 100 respondents who were reproductive age women in Beru Village, Blitar Regency between June-July 2021. The findings showed that there was a relationship between the level of knowledge of women of childbearing age and the level of adherence to using birth control pills appropriately (p < 0.05).

Monitoring Land Cover Change in Katsina Urban Area, Nigeria (1999 -2017) Associated with Urbanization: A Pixel-based Individuality Forms of Image A nalysis

Objectives: To study the rapidly changing urban area of Katsina in Katsina State; Nigeria, to track Land Cover Changes (LCC) and to identify possible impacts of urbanization. Methods: Landsat thematic mapper (TM), enhance thematic mapper (ETM +) images 30m resolution from the United States Geological Survey (USGS) acquired from Jos National Centre for Remote Sensing (NCRS). Satellite images from 1999 and 2017 were used to create a past and current picture of the LCC in the urban area of Katsina. The images were classified using the pixel identity forms of the digital organization of the monitored images with a maximum-likelihood classifier algorithm based on the multispectral image to understand the spectral data presented in the image of the urban area of Katsina. These images were then compared with the modifications that occurred among the dates of images. Findings: The findings on study area showed that the built-up area had increased and added 4.99 square kilometres (percentage change of 22.22) between 1987 -1999. The class of vegetation/agricultural land cover also increased and added 10.4 square kilometres (percent change of 165.8) between 1987 -1999. The Bare-soil had decreased and lost 15.39 square kilometres (percent change of 25.29) between 1987 -1999. Conclusion: Land cover changes exist, either legal or illegal, which indicate the rapid rate of population growth and urbanization in the urban area of Katsina. It also revealed the capability of RS/GIS for managing large information that made it suitable for these types of study.

Role of Neighborhood Design in Reducing Impacts of Development and Climate Change, West Sherwood, OR

We used the EPA SWMM-5. 1 model to evaluate the relative impact of neighborhood design and constructed Low Impact Development (LID) features on infiltration, evaporation, and runoff for three future scenarios. In the Current Course (CC) future, current regulations and policies remain in place under lower rates of climate change and population growth. In the Stressed Resources (SR) future, rapid rates of population growth and climate change stress water systems, and conventional development patterns and management actions fail to keep pace with a changing environment. In the Integrated Water (IW) future, with the same rapid rates of climate change and population growth as the SR future, informed water management anticipates and adapts to expected changes. The IW scenario retains public open space, extensive use of constructed LID features, and has the lowest proportion of impervious surface. Neighborhood designs varied in the number of dwelling units, density of development, and spatial extent of nature-based solutions and constructed LID features used for stormwater management. We compared the scenarios using SWMM-5.1 for a set of NRCS Type 1a design storms (2-yr, 25-yr, 20% increase over 25-yr, 30% increase over 25-yr) with precipitation input at 6-min time steps as well as a set of 10-year continuous runs. Results illustrate the importance of neighborhood design in urban hydrology. The design with the highest proportion of impervious surface (SR future) produced runoff of up to 45–50% of precipitation for all variations of the 25-year storm, compared to 34–44 and 23–39% for the CC and IW futures, respectively. Evaporation accounted for only 2–3% of precipitation in the 25-year design storm simulations for any scenario. Results of continuous 10-year simulations were similar to the results of design storms. The proportion of precipitation that became runoff was highest in the SR future (33%), intermediate in the CC (16%), and lowest in the IW future (9%). Evaporation accounted for 6, 11, and 14 of precipitation in the SR, CC, and IW futures with LID, respectively. Infiltration was higher in scenarios with LID than for the same scenario without LID, and varied with the extent of LID employed, accounting for 59, 71, and 74% of precipitation in the SR, CC, and IW scenarios with LID. In addition to differences in performance for stormwater management, the alternative scenarios also provide different sets of co-benefits. The IW and SR future designs both provide more housing than the CC, and the IW future has the lowest cost of development per dwelling unit.

Transit-Oriented Development: An Approach to Sustainable Development Locus: Jatinegara Station, East Jakarta

The rapid rate of population growth is a critical problem worldwide. The increase in population causes many problems, especially in the provision of housing with limited land in urban areas. These problems cause disruption of the social environment and reduce the quality of the environment. Transit Oriented Development (TOD) is one of the alternative solutions in solving these problems, with the concept of city development that maximizes diverse and integrated land use by promoting healthy lifestyles through walking and cycling and maximizing the use of mass transportation modes. Therefore, this research was conducted with the aim of knowing the application of TOD development for planning to achieve a sustainable city. This study reveals how transit-oriented development design and policies help in achieving sustainable development despite having to maintain high density. With this research, it is hoped that it can provide input to local governments, especially the East Jakarta City Planning Service in the context of structuring and developing the Jatinegara station area.

Rural-urban disparities in the nutritional status of younger adolescents in Tanzania.

Research on geographic differences in health focuses largely on children less than five years; little is known about adolescents-and even less regarding younger adolescents-a vulnerable group at a critical stage of the life course. Africa's rapid population growth and urbanization rates, coupled with stagnant rates of undernutrition, further indicate the need for country-specific data on rural-urban health disparities to inform development policies. This study examined rural-urban disparities in body mass index-for-age-and-sex (BAZ) and height-for-age-and-sex z-scores (HAZ) among younger adolescents in Tanzania. Participants were randomly selected adolescents aged 10-14 years (N = 1,125) residing in Kilosa (rural) and Moshi (urban) districts of Tanzania. Individual and household-level data were collected using surveys and anthropometric data was collected on all adolescents. Age, sex, household living conditions, and assets were self-reported. BAZ and HAZ were calculated using the WHO reference guide. The prevalence of undernutrition was 10.9% among rural and 5.1% among urban adolescents (p<0.001). Similarly, stunting prevalence was greater in rural (64.5%) than urban (3.1%) adolescents (p<0.001). After adjusting for covariates, rural residence was significantly and inversely associated with BAZ (B = -0.29, 95% CI: -0.52, -0.70, p = 0.01), as well as with HAZ (B = -1.79, 95% CI: -2.03, -1.54, p<0.001). Self-identified males had lower BAZ (B = -0.23, 95% CI: -0.34, -0.11, p<0.001) and HAZ (B = -0.22, 95% CI: -0.35, -0.09, p = 0.001) than self-identified female adolescents. Rural-urban disparities in nutritional status were significant and gendered. Findings confirm place of residence as a key determinant of BAZ and HAZ among younger adolescents in Tanzania. Targeted gender-sensitive interventions are needed to limit growth faltering and improve health outcomes in rural settings.

Which Gridded Population Data Product Is Better? Evidences from Mainland Southeast Asia (MSEA)

The release of global gridded population datasets, including the Gridded Population of the World (GPW), Global Human Settlement Population Grid (GHS-POP), WorldPop, and LandScan, have greatly facilitated cross-comparison for ongoing research related to anthropogenic impacts. However, little attention is paid to the consistency and discrepancy of these gridded products in the regions with rapid changes in local population, e.g., Mainland Southeast Asia (MSEA), where the countries have experienced fast population growth since the 1950s. This awkward situation is unsurprisingly aggravated because of national scarce demographics and incomplete census counts, which further limits their appropriate usage. Thus, comparative analyses of them become the priority of their better application. Here, the consistency and discrepancy of the four common global gridded population datasets were cross-compared by combing the 2015 provincial population statistics (census and yearbooks) via error-comparison based statistical methods. The results showed that: (1) the LandScan performs the best both in spatial accuracy and estimated errors, then followed by the WorldPop, GHS-POP, and GPW in MSEA. (2) Provincial differences in estimated errors indicated that the LandScan better reveals the spatial pattern of population density in Thailand and Vietnam, while the WorldPop performs slightly better in Myanmar and Laos, and both fit well in Cambodia. (3) Substantial errors among the four gridded datasets normally occur in the provincial units with larger population density (over 610 persons/km2) and a rapid population growth rate (greater than 1.54%), respectively. The new findings in MSEA indicated that future usage of these datasets should pay attention to the estimated population in the areas characterized by high population density and rapid population growth.

Review on Determinant of Rural Livelihood Strategy and Household Food Security in Ethiopia

The livelihood of most people in Ethiopia depends on survival agriculture whose carrying capacity has reduced due to rapid population growth rate and farm size reduction. The main objective of this review is to identify the determinant of rural livelihood strategy and household food security in Ethiopia. Data was collected from different research papers that have to do with the determinant of rural livelihood strategy and household food security in Ethiopia. According to the review result disguised agricultural employment, inadequate access to fertile land, lack of access to farm input, markets, deterioration of natural resource base and incomplete credit among others, wage-earning opportunities, investing in children education, Age of the household head, distance from irrigation sources, social status, soil fertility status, education level, distance from DA office, Economical Active members, soil fertility status, soil conservation and transportation services, saving to invest, and availability of growth engines like private investments were the determinant of rural livelihood strategy and sex, ceremonial expense, dependency ratio, marital, land size, education, livestock and pesticide were the determinant of rural household food security in Ethiopia. In addition to these, the review is forward the concrete recommendation, which implies helping to improve rural household livelihood and household food security through basic policy implication and the participation of the rural household.

LAND DEMARCATION AND DESIGNING OF WASTE TRANSFER STATION USING GIS TECHNIQUE FOR LAHORE CITY, PAKISTAN

Rapid population growth and high rate of urbanization make municipal solid waste management a challenging task for municipalities. Lack of sufficient infrastructural facilities worsen this challenging situation. To curb this, transfer stations, which are facilities located close to residential areas and are used to receive and hold waste temporarily until it is transported to distant landfills. It reduces waste transportation cost and provide a place for waste segregation. In Lahore open transfer station is built near river Ravi and residential areas which is creating air and land pollution. This study is carryout to select the suitable location for waste transfer station in Lahore that meets the USEPA criteria. Buffer command of Arc GIS is used for site selection. Best suitable sites selected for Lahore in this analysis are UC Sultanki and UC Chandrai where more buffers are joint during buffer analysis. Furthermore, cost estimation for the construction and operation of both waste transfer stations are done.

Assessment of Public-Private-Participation of Solid Waste Management: A Case Study Warri, Nigeria

The menace of indiscriminately disposed heaps of refuse in most urban centers in Nigeria is a confirmation of the inability of the government to cope with the ills associated with rapid population growth rate and urbanization. This study assessed the participation of the private sector in the management and recycling of solid wastes as they together with the public sector strive to attain healthy and neat cities. The Actor Network Theory (ANT) was used as a framework to illustrate the interrelationship, interdependence and co-existence of the different participants in the management of solid waste. This co-existence was revealed to generate several challenges especially for the major Actors such as that of the preference of informal private waste collectors to the registered contractors assigned by the government to their residential areas and the hindrances posed by community youth on Private Sector Participant (PSP). However, from the study it was revealed that the introduction of Private Sector Participant was not enough to check the problems associated with solid waste management. Rather, a holistic approach where all actors, whether householders, formal or informal waste collector, scrap collectors, NGOs or CBOs should be considered by the Government in the policy formulation and implementation in sustainable solid waste management practices.
