Bangladesh is the 2nd largest growing economy in the world in 2016 with 7.1% GDP growth. This study undertakes an econometric analysis to examine the relationship between population growth and economic development. This result indicates population growth adversely related to per capita GDP growth, which means rapid population growth, is a real problem for the development of Bangladesh. Malthus’s prediction is that population increases so rapidly and outstrip the food supply due to the operation of the law of diminishing return, which is proven wrong because of technological improvement, human capital development and so on in Bangladesh. Bangladesh has reduced its population growth by about 67% between 1979 and 2017 using different preventive checks suggested by Malthus and Mill. Bangladesh has been suffering from environmental degradation, loss of arable land, loos of agricultural land biodiversity loss and deforestation.  As a consequence, the climate has changed dramatically, and species are in danger and extinction. Bangladesh Economy is growing with improving living standard at the cost of environmental degradation.

Landscape Transformation

Abstract Studies have shown that information on landscape transformation is an important benchmark data set because of its value as an environmental change indicator. Therefore, dynamism of landscape transformation over a 34-year period are analysed for a case study in Ibiono-Ibom, Akwa-Ibom State, Nigeria. The study adopted a mixed method consisting of remote sensing and GIS-based analysis, and semi-structured interviews covering 400 households while factors contributing to landscape structures and changes are studied. The results point out three main driving factors responsible for the landscape transformation in the study area: agricultural practices which lead to intensification of forest resources, riparian vegetation, vegetated wetlands and non-vegetated wetlands; urbanization which modifies the structure and morphology of the landscape, and finally, population growth directly related to massive infrastructural development which encroached on all other land spaces. GIS-based analysis of remotely-sensed data showed that built-up area had increased by 7535.2 ha between 1986 and 2020; shrub and arable land by 1343.9 ha and light forest decreased by 4998.3 ha. While bare-land reduced by 1522.1 ha; vegetated wetland reduced by 1092 ha; water body coverage reduced by 168 ha and non-vegetated wetland size also reduced by 2029.4 ha. Analysis of household survey results revealed that the perceptions of respondents validate the observed patterns during the remotely-sensed data analysis phase of the research, with 54 % (n=400) of respondents reporting a decline in agricultural land use, and 19.3 % (n=400) observing a decline in forest areas in the study area. Furthermore, agricultural intensification, urban development, timber exploitation, firewood collection and increase in settlements were identified as the proximate drivers of these observed landscape transformation dynamics in the study area. The study concluded that the variation in landscape transformation of the study area are clear indication of the extent of biodiversity loss and ecosystem degradation in the study area.

Abstract While there are enormous studies on climate change in stable countries, climate policy perspectives from conflict-prone regions including Somalia are limited. This study investigates the asymmetric impact of energy and economic growth on environmental degradation in Somalia—by employing nonlinear autoregressive distributed lag model (NARDL) and causal techniques from 1985 to 2017. We find asymmetric long-term cointegration among the variables, whereas energy consumption and economic growth asymmetrically affect environmental degradation. Besides, the causal inferences reveal unidirectional causality from environmental pollution to positive change in energy consumption. Additionally, we find unidirectional causality from negative shock in economic growth to positive shock in economic growth. Moreover, a bidirectional causality is observed between population growth and negative change in economic growth. A unidirectional causality is confirmed from positive shock in economic growth to population growth—from negative change in economic growth to negative shock in energy consumption—from positive change in economic growth to positive shock in energy consumption—and negative change in energy consumption to population growth. This calls for the implementation of clean energy investment policies, good farming methods, and improved grazing land policies. The adoption of these policies will improve both environmental quality and sustained economic development.

The study examined the relationship between agricultural land use and population growth rates from 1961 to 2018 in Nigeria. Secondary data were obtained from Food and Agricultural Organization and the World Bank. Descriptive statistics, trend equation and correlation analyses were used. Findings revealed that agricultural and arable land utilization grew at the rate of 0.62% and 0.72%, respectively per annum; while the total population growth rate stood at 2.57%. Also, urban and rural population grew at a rate of 4.75% and 1.67% respectively. In addition, the agricultural and arable land utilization rates had significant positive correlations with the total population, urban and rural population. Besides, the findings revealed that, agricultural land (to total land ratio) has continued to increase and currently averaged at 68.78% indicating massive land expansion put under agricultural used. Findings revealed that, most arable crop outputs increase majorly from land expansion rather than land productivity, a situation that cannot assure sustainable agricultural land use food security in a near future. Hence, the country needs agricultural land sparing policies and technologies to slow the current agricultural land expansion drive. Besides, the country’s agricultural land policies should focus on achieving land productivity and sustainable land-sharing strategies among major land users in the country. Again, the rural population growth rate is lower than the urban growth rate, implying that, the rural population is deteriorating with its probable negative effect on farm labour. This needs to be addressed urgently if the sustainable agricultural system is to be achieved in the near future in Nigeria.

Growing Population

Economic development and population growth in the poor areas of the earth is a subject of an essential concern for the environmental economists. Developing countries are facing and suffering by the serious problem of high population growth which is causing environmental degradation. A rapidly growing population exerts pressure on agricultural land and raises demand for food and shelter which encourages the conversion of forest land for agricultural and residential uses, now we know that growing population is a major cause of air, water, and solid waste pollution. The world population was 2.52 billion in the year 1950, which increased to 6.06 billion in 2000 and is likely to reach 8.3 billion by the year 2030. While the population size will remain almost stationary in the economically developed part of the world, around 1.2 billion, during the same period population is likely to grow in the less developed regions. This is likely to pose challenges for the economic growth and pressure on environmental resources in the developing countries. Furthermore, most of the population growth in the developing countries is likely to be concentrated in the urban areas. This has implication for increased demand for energy and water resources in the urban areas. This will also pose challenges for the management of increased solid waste, air and water pollution. One of the striking experiences of the developing

Abstract Agricultural land use has recently peaked, both globally and across country income groups, after centuries of expansion and intensification. Such shifts in the evolution of global land use have implications for food security, biodiversity loss, and carbon emissions. While economic growth and land use are closely linked, it is difficult to determine the extent to which the relationship is causal, deterministic, and unidirectional. Here we utilize gridded datasets to study long-term global land use change from 1780 to 2010. We find evidence for an economic tipping point, where land use intensifies with economic development at low income levels, then reverses after incomes reach a critical threshold. Cropland peaks around $5000 GDP per capita then declines. We utilize a Markov model to show that this reversal emerges from a variety of divergent land use pathways, in particular the expansion of protected areas and a reduction in land use lock-in. Our results suggest that economic development remains a powerful driver of land use change with implications for the future of natural ecosystems in the context of continued population and income growth.

Most sub-Saharan African (SSA) nations are governed by traditional economic models of using varied varieties of capital (including human), technological and natural approaches to supply goods and services. This has undoubtedly led to annual economic growth of about 3.2% in several African nations and higher per capita income as some of the major benefits, which have improved the standards of living and social wellbeing but conjointly have led to environmental degradation. In response to the environmental degradation problem, while benchmarking against international policies, this article evaluates approaches to economic development, environmental management, and energy production in the context of climate change. Case studies consider the mine-dependent nations of Zambia and the Democratic Republic of Congo (DRC) and the agriculture-dependent nation of Rwanda. In Zambia and DRC, energy efficiency in the mining and metals industries could increase the electrification rate in Zambia and DRC by up to 50%. Additional industrial utilization of solar or wind energy is key to a stable energy supply, economic development and environmental protection. In Rwanda, population growth and land constraints point to economic growth and agricultural improvements as the key to sustainability and sustainable development. These case studies emphasize resource optimization, energy efficiency, renewable energy deployment, strategies to reduce biodiversity loss and environmental degradation, and the improvement of social wellbeing for both present and future generations to achieve an ecologically enhanced sub-Saharan Africa.

Due to alterations in physiographic and social-economic conditions, climatic changes, adaptation and population growth, the land use pattern of Bangladesh is changing very rapidly. Bangladesh is a small country but it bears a huge population, resulting in a very high density of population and very high intensity of land and resource use. Per capita land is estimated to be only about 0.0526 ha. Two significantly prominent phenomena driving country’s overall scenario of economic development and environment imbalance include: (a) the high growth rate of population engulfing precious land for settlement and (b) scarcity of land for ever increasing demand of food. As a result, the land use pattern of the country is changing at a great momentum. Every year the country is losing 1% arable land due to the population growth and its infrastructure development. This study was conducted on Rajshahi District where the major focus was to see the land use pattern of the area, trend in the change of land uses, and in particular, challenges for the agricultural land. For analyses remotely sensed data (Landsat MSS-1977, TM-1990 and TM- 2010) and GIS techniques were used and secondary data were collected from SPARRSO, published and unpublished data regarding crop, population and other ambient information from mostly government sources. Results show that the land use pattern of Rajshahi District is changing, especially the agricultural land is decreasing in an alarming rate and now it is become more and more vulnerable. The agricultural land of the study area is losing 0.46% per year and the area under infrastructure use is increasing 5.86% per year. If this rate continues, the agricultural land will be totally eliminated within the next 217 years. DOI: http://dx.doi.org/10.3329/jles.v6i0.9724 JLES 2011 6: 69-74
