The two variables of population and development affect each other in an indirect manner in which when population increase happens, development is reduced. The two effectively impact quality of life. It is strongly recommended to control population in order to achieve development. Sociologists are widely responsible to create the balance of population and development. As resources are limited in each country, an organized and planned population is needed towards any development. The phenomenon development being multi-lateral, needs an appropriate population size. It is worth mentioning that population naturally grows, but resources for development do not. Overall, Asia, Africa, and Latin America had very high population growth rate of 2.1% between 1955 and 1975. Fortunately, increase of literacy and education has caused population growth rates to decline in the past two decades in many parts of the developing countries. The only part of the developing world with high population growth rate is Africa in which the population will increase to over 4.2 billion by the year 2100; threatening other parts of the world. Such a situation will widely endanger quality of life.

High Population Growth

Bengkulu City is the center for almost all activities and has a high population growth rate. Because of the high population growth rate, human needs for space and land will increase. Land availability will continue to decline, while it cannot increase the existing area. This will impact the carrying capacity of the environment, so it needs predictions for land availability. This study used a spatial dynamics model which is an analysis of the dynamic system model and the suitability of the built-up area. The carrying capacity to reach excellent quality when the length of the built-up area is 30-70% of the total area that can be used. The results showed that the built-up area will reach 70% in 2030, which means it will exceed the environmental carrying capacity threshold. The results showed there were differences between the distribution patterns of built-up area in the spatial dynamics model and Spatial Planning Bengkulu City in 2032 at Kampung Melayu Subdistrict, Selebar Subdistrict, Singaran Pati Subdistrict, and Sungai Serut Subdistrict.

Number Of Individuals

Translocation—moving individuals for release in different locations—is among the most important conservation interventions for increasing or re-establishing populations of threatened species. However, translocations often fail. To improve their effectiveness, we need to understand the features that distinguish successful from failed translocations. Here, we assembled and analysed a global database of translocations of terrestrial vertebrates (n=514) to assess the effects of various design features and extrinsic factors on success. We analysed outcomes using standardized metrics i.e. a categorical success/failure classification, and population growth rate. Probability of categorical success and population growth rate increased with the total number of individuals released but with diminishing returns above about 20-50 individuals. There has been no increase in numbers released per translocation over time. Positive outcomes—reported success and high population growth—were less likely for translocation in Oceania, possibly because invasive species are a major threat in this region and are difficult to control at translocation sites. Increased rates of categorical reported success and population growth were found for Europe and North America, suggesting the key role of historical context in positive translocation outcomes. Categorical success has increased throughout the 20th century, but that increase may have plateaued at about 75% since about 1990. Our results suggest there is potential for further increase in the success of conservation translocations. This could be best achieved by greater investment in individual projects, as indicated by total number of animals released.

Large Response

Recent research in Kenya shows that, although there is still a high population growth rate, there is increasing interest among men as well as women in family planning and in limiting family size. Vasectomy, however, is little known and practiced in Kenya. A major reason for this is a general lack of knowledge about the procedure and where it may be obtained. Little effort has been put into addressing the barriers to vasectomy acceptance in Kenya, partly because of the commonly held assumption that Kenyan men would not be interested in the method. Innovative Communication Systems, with the support of the Association for Voluntary Surgical Contraception, implemented a study using the print media to examine this perception. Advertisements providing information about the method were placed in newspapers and a magazine. An unexpectedly large response was received—over 800 written requests for information from all parts of the country. The majority of inquiries were from rural areas, and there was a high proportion of requests from the coastal district, a Muslim area generally considered to be extremely resistant to family planning. A large proportion of inquiries came through a Kiswahili newspaper appealing to lower socioeconomic groups.
