The population,agriculture, and environment nexus in Latin America: country-level evidence from the latter half of the twentieth century

Unprecedented population growth and migration accompanied equally unprecedented land use and land cover change in Latin America during the latter decades of the twentieth century. Country-level data are examined with bivariate statistics to determine relationships between changes in population patterns and land use (agriculture and forest cover) from 1961 to 2001. In South America, large forest areas were eliminated during the period, while exceptionally high rates of forest clearing were ubiquitous in the Central America/Caribbean region. These environmental changes accompanied dissimilar initial population densities and different effects of population change on agriculture. While interacting with a host of political, socio-economic, and geographic processes, it appears that both Malthusian and Boserupian demographic processes were important drivers of deforestation. Given continued, though slowing, population growth, increased urban consumption, and future land use constraints, policy makers face myriad challenges in advancing sustainable agriculture-population dynamics in Latin America.     

Property Size and Land Cover Change in the Brazilian Amazon

This paper considers the size of a farmer’s property as a key variable influencing land cover and land cover change in rural areas of developing countries. Data from 126 rural familial properties in the region around the city of Santarém, Pará, in the Brazilian Amazon, indicate that property size is important for understanding the trajectories of land cover change. Past research has focused on the distinction between small family farms and large capitalized farms, arguing that family farmers have a higher deforestation intensity, or on estimating the strength of the effect of property size relative to economic or demographic factors. This paper shows that larger familial properties are able both to retain a larger area in forest and to have long enough cycles of use and fallow to allow previously used land to become forested again. Based on these analyses and discussion, we argue that land use and land cover research must consider property size as an organizing principle in order to better comprehend the reciprocal relationship between population and environment in frontier areas of the Brazilian Amazon and other rural landscapes.     

Combining vertical service with horizontal service to promote family planning]

How Bazhong County of Sechuan Province, China, carries out family planning through a combination of what are termed vertical and horizontal services is described. Vertical service refers to assistance such as premarital education, prenatal hygiene, child health care, and family planning, while horizontal service refers to household assistance for married women. Premarital education is designed to help young people acquire sufficent knowledge about family planning, hygiene, and eugenics, and stresses the disadvantages involved in marriages between close relatives. Prenatal hygiene provides safe and convenient medical accommodations for delivery of the child as well as maternal care. Child health services assure that the best facilities are to be made available for physical examinations, vaccinations, and medical treatment. The family planning program involves comprehensive measures such as distribution of contraceptives and safe sterilization. In addition, the county provides medical assistance for couples unable to have children. Horizontal service providing household assistance for married women promotes scientific farming (e.g., how to use fertilizer), helps people increase their income by teaching them skills, and provides social services to improve life style and education. These vertical and horizontal services have brought about substantial improvements in the standard of living, family harmony, and population control.     

Economic development and fertility decline: lessons from Asia's newly industrialized countries

The general thesis that economic development and fertility decline are interrelated is substantiated in literature that discusses the successes of the newly industrialized countries of Hong Kong, Korea, Singapore, and Taiwan. When countries are developing rapidly, family planning accelerates the rate of fertility change, particularly among the poor uneducated rural population. Relying on economic and social development is not enough. National policy in Hong Kong, Singapore, Korea, and Taiwan recognized that population growth drains resources and the family planning programs operating since the 1960s contributed to a drop from 5 children/woman to 2 by 1988, and 70% of married couples used contraception. Coupled with this, age at marriage rose, contraception became more available, and educational and employment opportunities increased. Economically, the growth rate in the 1980's was 6-10% annually, with growth in the manufacturing and service sectors and export trade. Close economic ties evolved between governments and private sectors. Social development programs had been fully funded and gains evident in education, living standards, health care and nutrition, and life expectancy. The success of family planning is attributed to encouraging contraceptive awareness and use. Fertility reduction may occur with social and economic development, but no developing countries have reduced fertility without family planning. The relative importance of family planning may change over time, and reducing the cost through government sponsored family planning programs and encouraging the acceptability of contraceptive usage.     

Policy review: thoughts on addressing population and climate change in a just and ethical manner

Many believe that linking population growth to the issue of climate change will help to place family planning back into the political realm as an urgent matter of national and environmental security. Others worry, however, that focusing on the environmental impacts of demographic change places at risk the hard-fought and long-developed global consensus that individual rights and empowerment are what matters most in fostering sustainable development and stabilizing population growth. This paper focuses on United States population policy. It presents a brief historical background and summarizes the state of scientific evidence regarding the impacts of population growth on climate change. It then analyzes some of the underlying ethical issues involved in advancing an advocacy argument around increasing family planning as a way to slow population growth and mitigating climate change. Finally, it recommends a way in which advocates can frame the connections between population growth and climate change in a just and ethical manner.     

Household demographic change and land use/land cover change in the Brazilian Amazon

Demographic interest in population and environment has grown in recent decades. One of the most prominent research areas in this tradition addresses the impact of population on land use and land cover change. Building on this tradition, we examine the effects of household demographic composition on land use and land cover on small farms in two study areas in the Brazilian Amazon. Fixed effects regression models of used area and forested area show few consistent effects of changes in household demography on land use and land cover change. Effects are inconsistent with the household life cycle model that currently dominates the literature on household demographic effects in frontiers. Changes in the number of children and women, particularly young women, have the most significant effects on land use and land cover change. We conclude by arguing that households strategically access cash for investment in agriculture and that specific strategies are determined by economic and institutional context.

China's first family planning publicity month

China conducted its 1st nationwide Family Planning Publicity Month in 1983, from New Year's Day to Spring Festival (February 13). The campaign emphasized the rural areas and focused on explaining why family planning is a state policy. The most noticeable achievements of this campaign were that every household became familiar with the fact that family planning is a basic state policy. The majority of the population take this policy seriously, realizing that strict control of population growth is both a good and imperative policy. More than 1,830,000 propaganda columns and photo exhibitions were displayed, 5,900,000 radio and television programs broadcast, 2,010,000 theatrical performances, movie and slide showings presented, and 97,000,000 copies of materials published for public dissemination. The activities were varied and interesting, vivid and lively, and purposeful and persuasive. 1 of the most effective methods of publicizing population control has been the presentation of comparative statistics. This aspect of the campaign was a specific and lively form of education in population theory and practice. The presentation of statistics that show the relationship among population, land use, grain produce, and income enabled the population to reason out why population growth needs to match economic and social development. Another important accomplishment of the publicity month was that a large number of couples of reproductive age became convinced of the need to use contraception. According to the incomplete statistics, 8,860,000 people had surgical operations for birth control. The universal promotion of ligations by either partner of a reproductive couple who already had given birth to a 2nd child was an important development of family planning technique promoted simultaneously with the promotion of IUDs. The increase in the number of people doing family planning work was another achievement of the publicity month. More than 15,240,000 publicity personnel and 760,000 medical personnel were trained. The enthusiasm of the Party and the people contributed to the success of the publicity month. The success of the publicity month is inseparable from the achievements and experience gained through China's longterm pursuit of family planning.     

Household demographic factors as life cycle determinants of land use in the Amazon

This paper seeks to broaden the application of demographyto environmental studies by complementing existing macro-level approaches, which feature aggregate populations, with a micro-level approach that highlights household life cycles. I take up the case of small farm households in the Brazilian Amazon to present a theoretical framework that identifies demographic characteristics which dispose families to engage in different forms of land use as household age structures change. Empirical models show that net of theeffects of farmer background, neighborhood context, institutional context, and off-farm incomes, demographic variables indicative of the household life cycle exert significant effects on the prominence of land uses with distinct environmental ramifications. The findings not only reveal micro-level demographic factors which affect Amazon land cover, they yield implications forfuture changes in rainforest landscapes in northern Brazil, and suggest household life cycle models as an avenue for further demographic research on environmental change in Latin America and other contexts.     

中国各地区人口年龄结构变动的消费效应分析

消费是影响一国经济增长的重要因素,对于影响消费的众多因素研究,大多基于收入分配不均和收入不确定性视角,而忽略了另外一个非常重要的因素,那就是人口年龄结构变化对消费的影响效应。上世纪70年代计划生育政策的推行和人口预期寿命的延长,加快了我国人口转变及老龄化发展的步伐,这一转变必将改变居民的储蓄消费行为,影响储蓄-消费模式和消费率。基于我国2002-2008年省级面板数据,本文研究了各地区人口转变对消费率的影响。研究表明,消费率与少儿抚养比、老年抚养比之间分别存在正相关关系与负相关关系。     

Agricultural production responsibility system and the work of family planning in the rural area]

With the establishment of the agricultural production responsibility system, the entire agricultural management and economic system has undergone great changes, and family planning in rural areas has met with many difficulties. Because of this responsibility system, households with more manpower seem to become wealthy more rapidly than others. An existing belief among the rural population is that more children will provide a larger labor force and thus more income. Birth control and family planning are therefore becoming more difficult. In order to change existing beliefs, a comprehensive ideological education for peasants is needed so that they may understand the question of birth control from the viewpoints of national interests. Economic rewards and administrative restrictions may be used as necessary birth control measures. Agricultural production and family planning can be managed well if there is close contact and cooperation between the cadres and the masses. Extra care and benefits should be given to women of childbearing age who undergo birth control operations and agree to a single child in each household. Welfare programs for the masses, such as kindergartens and nursing homes must be established in order to reduce their worries. In addition, efforts are needed to study the new situation and solve new problems. The goal of controlling the rural population growth should be achiefed through practical work and experience.     

Family planning promotes social and economic development of Dongguan County]

Examination of the effects of family planning indicates 6 major social and economic changes which it has brought about in Dongguan County, China. Peoples' views on family planning have changed: they no longer believe the old notion that "more children guarantee a better life" and have done away with the convention of early marriage and early childbearing. The number of children per household has dropped from an average of 5.9 in the early 1950s to its present average of 2.05. The situation of women has undergone important changes. In the past, women bore many children and few worked outside the household. Today, in the city of Guancheng, 7000 of the 10,000 workers in city-owned factories are women. A 3rd effect of population control is increased production output and a better standard of living. Since 1979 when economic reform began, 90% of the presents built new homes and 70% of the households bought high standard consumer goods. A 4th improvement has been found in the development of education: 99.7% of school-age children attend elementary schools and the rate of graduating students is 98.2%; 92% of preschool children are involved in preschool programs; and 67,000 young women attend various kinds of vocational schools. A more civilized life style and more harmonious family lives have found as a 5th result of family planning measures. Finally, there have also been improvements in welfare and public sanitation facilities. For example, more than 200 water plants have been built in the county and 41% of the population drinks water which meets sanitation standards. It is concluded that the beneficial results of population control reported in this study should be of interest to all those involved in the field of family planning.     

An analysis of the size of the family household and family structure in China]

Since 1949, great social and economic changes have taken place in China. The entire economic structure and social relations are no longer the way they used to be. These changes have also had a strong impact on the size of family households and family structure. Major changes are summarized as follows: (1) The size of the present family household has been greatly reduced from its earlier size. The main reason for this reduction in size is the change of the social system. Under the new social system, the natural population growth rate and family structure have shown the greatest change from the past. (2) The major change in family structure is that small families have replaced the traditional large families. Under the large family system, several generations may stay together as one household, and brothers do not divide the large family even after they are married. Under the small family system, a household is normally limited to the parents and their children. With the gradual disappearance of large families, small families are increasing rapidly. Some households with three generations living together are still in existence, and the young and the old may support each other in their daily life. Both in cities and in rural areas, the traditional custom of respecting one's old parents still exists. There must be a value and necessity for the existence of this particular kind of family structure.     

Population growth and poverty in the developing world

The links between rapid population growth and the absolute poverty currently affecting 780 million people in the developing countries (excluding China and other centrally planned economies) were examined. Absolute poverty is defined as having less than the income necessary to ensure a daily diet of 2150 calories per person ($200 per person a year in 1970 United States dollars). Focus is on poverty and demography in the developing world (defining poverty; income, fertility and life expectancy; demographic change and poverty), effect of poverty on fertility, family planning programs and the poor, and the outlook for the future. Rapid population growth stretches both national and family budgets thin with the increasing numbers of children to be fed and educated and workers to be provided with jobs. Slower per capita income growth, lack of progress in reducing income inequality, and more poverty are the probable consequences. Many characteristics of poverty can cause high fertility -- high infant mortality, lack of education for women in particular, too little family income to invest in children, inequitable shares in national income, and the inaccessibility of family planning. Experience in China, Indonesia, Taiwan, Colombia, Korea, Sri Lanka, Cuba and Costa Rica demonstrate that birthrates can decline rapidly in low income groups and countries when basic health care, education, and low-cost or free family planning services are made widely available.     

A better future is ahead of us

China's family planning program is implemented under the unified leadership of the Chinese government. The main responsibilities under this program are to set up and strengthen family planning offices at all levels, formulate relevent laws and regulations, work out programs, principles, and policies for population growth, carry out intensive publicity and education, speed up scientific and technological research on family planning, and mobilize all the people and related departments to support the work of family planning. Family planning in China is practised on a voluntary basis. Education on patriotism is conducted among the people to enable them to see that strict control of population growth and conscious practice of family planning according to policy have a crucial bearing on China's prosperity and well being. As shown in practice, China has not only succeeded in maintaining sustained and steady economic growth, but has also succeeded in drastically reducing the population birth rate, death rate, infant mortality rate, and in extending average life expectancy. This demonstrates the superiority of China's socialist system. To control the growth of the population is an extremely arduous task. However, as long as China keeps to a practical and effective policy, the goal of keeping the total population at around 1.2 billion by the end of the century can be attained.     

India's population in transition

This demographic profile of India addresses fertility, family planning, and economic issues. India is described as a country shifting from economic policies of self-reliance to active involvement in international trade. Wealth has increased, particularly at higher educational levels, yet 25% still live below the official poverty line and almost 66% of Indian women are illiterate. The government program in family planning, which was instituted during the early 1950s, did not change the rate of natural increase, which remained stable at 2.2% over the past 30 years. 1993 marked the first time the growth rate decline to under 2%. The growth rate in 1995 was 1.9%. The total population is expected double in 36 years. Only Nigeria, Pakistan, and Bangladesh had a higher growth rate and higher fertility in 1995. India is geographically diverse (with the northern Himalayan mountain zone, the central alluvial plains, the western desert region, and the southern peninsula with forest, mountains, and plains). There are regional differences in the fertility rates, which range from replacement level in Kerala and Goa to 5.5 children in Uttar Pradesh. Fertility is expected to decline throughout India due to the slower pace of childbearing among women over the age of 35 years, the increase in contraceptive use, and increases in marriage age. Increased educational levels in India and its state variations are related to lower fertility. Literacy campaigns are considered to be effective means of increasing the educational levels of women. Urbanization is not expected to markedly affect fertility levels. Urban population, which is concentrated in a few large cities, remains a small proportion of total population. Greater shifts are evident in the transition from agriculture to other wage labor. Fertility is expected to decline as women's share of labor force activity increases. The major determinant of fertility decline in India is use of family planning, which has improved in access and use during the 1980s. If India is to keep a stable population under 1.6 billion in the future, Indians may have to accept only one child per family.     

The international family planning movement

Over the past 3 decades, the number of women using family planning has increased 6-fold to over 400 million married women of childbearing age. The evolution of behavior and attitudes toward using birth control among third world couples reflects the goals and hard work of an international network of individuals, governments and organizations. This article follows the progression of this movement, from early opposition in developed as well as developing countries, to the present day, when birth control is practiced by a slight majority of the world's women of childbearing age. Among world regions, contraceptive use ranges from about 17% in Africa to 75% in Asia. In some African countries, however, family planning is still a foreign concept, and fewer than 5% of women use any birth control. International organizations played a crucial role in spread of family planning by providing training for developing country professionals, funding actual family planning programs and helping to evaluate programs. But the success of a country's family planning program also was dependent upon a national commitment, and often on a strong socioeconomic setting. The private sector has had a limited role except in some countries, notably in Latin America, but its involvement is likely to expand in the future. Also, as financial support from the US and international organizations wanes, national governments will cover a larger share of the cost. The worldwide increase in the practice of family planning has led to fertility declines in many third world countries, slowing rapid population growth rates. For individuals, family planning has been a liberating influence, allowing them to participate more fully in the shift from traditional to modern society.     

环境退化地区家庭人口对土地利用的影响研究——以中国西北毛乌素沙地为例

微观层面模型对于区分不同的人口群体以更好地明确环境退化的责任主体及其原因具有重要价值,对不同的土地利用方式进行经济区分是联接家庭人口特征与土地覆盖结果的重要手段。基于扩展的恰亚诺夫理论框架,文章利用2007—2008年两次调查所获293个农户样本数据,采用OLS和logit多变量模型实证分析毛乌素沙地家庭人口和其他因素对土地利用的影响。研究结果表明:(1)家庭人口因素对毛乌素沙地农户的土地利用产生重要影响;(2)毛乌素沙地主要土地利用的环境影响也遵循家庭生命周期的过程;(3)毛乌素沙地农户在减少有助于土壤修复利用活动的同时面临上升的退化风险。     

A sound population program

A sound population program must respond to real human needs, must be rooted in values, must generate results, must be administered in an integrated manner, must be based on the ethic and goal of self reliance and on the belief that it must operate and grow on its own steam, and must release human resources for productive economic endeavors. To make any sense at all, population must be linked to the gut level needs of the individual. People should not be viewed as demographic statistics, and the word human should be used in the basic sense of hunger and poverty. If the goal is to bring about lasting change in the way that Filipinos manage their lives and their living, it is necessary to probe their values. If social change is the goal, tradition must be challenged. In the area of family planning, persons who can communicate the fact that the program seeks to enrich life more than prevent birth must be chosen. There has been some criticism that the population/family planning program is "too contraceptive oriented" and too mechanistic in the approach to population. Contraception is behavior, a good measure of acceptance and an effective measure of commitment. The delivery of welfare must be horizontally integrated. Thus it is necessary to learn to work in teams, teams of development workers. The value of self determination and the conscious practice of planning and shaping one's life is the very logic of family planning. The program needs to implant the values of family planning firmly in the community, or, more accurately, in the small face to face primary groups where social norms are set and where change must take place if it is to last. The answer to how to achieve a sound population program lies less in what is done than how it is done.     

A preliminary analysis of negative population growth in Taicang County]

This report attempts to analyze the negative population growth and its significance in Tai-Cang County, China. Based on population data provided by local Tai-Cang authorities, family planning effectively lowered the birth rate from 11.9% between 1960-1969 to 3.0% between 1979-1983. The rate of single-child families grew enormously while the number of 2-child families reached a record low. Families with more than 2 children virtually vanished by 1983. Moreover, while a younger marriage age in 1981 and 1982 contributed to a slight increase in the birth rate, new marriage laws in 1983 caused an older marriage age and acted to lower the birth rate due to the fact that mothers were bearing children at an older age. A change in population components also influenced this low birth rate: the county population below the age of 14 is 21.2% compared with 33.6% nationally; however, the percentage of the population in this county over the age of 65 is 8.5% while the national figure is 4.9%. Finally, the marriagable population of females (i.e., 23 years old) was slightly lower between 1982-1984 due to the low birth rate seen from 1959-1961. The findings indicate that family planning is effective in lowering birth rates along with late marriages and older childbearing ages. The negative population growth in Tai-Cang County, however, is a temporary phenomenon. The indications are that the problems and shortcomings of family planning must be overcome, regional population planning must be improved, and the study of eugenics and optimum population reinforced. The report also notes that the population trend is toward aging.     

Survey of the population development of the minority Li of the Hai-nan Island]

Hai-nan Island is under the jurisdiction of Guangdong Province and has a population of 5,520,000, of which 85% belong to the Han ethnic group, and 13.4% to the Li ethnic group, and there are other small minorities. Since 1949, the population of Hai-nan Island has more than doubled, and a serious population problem exists. Among the minorities, the population growth for the Li people in 1 autonomous region of the Island has been very rapid for 2 reasons: 1) the large number of immigrants moving in from other places, and 2) a high fertility rate among the Li people. In order to slow down the rate of population growth on the Island, the 1st step should be to slow down the growth rate of the largest ethnic group, the Han people. The Li people live mainly in rural and poor areas, and their production level has been very low. In the past 30 years, tremendous progress has been made to improve the health care and livelihood of the Li people. Before 1949, the total number of Li people was only 300,000. By 1980, the Li population had increased to more than 740,000, more than doubling the 1949 figure. This rapid population growth has helped economic development in the areas inhabited by the Li people. On the average, each household in the Li autonomous region has 5.3 children. In order to further improve the living standard of the people, family planning is needed for the Li community. The traditional belief of having more children is currently undergoing a change in the minds of the Li people. The policy of offering economic reward to those who follow family planning regulations is working, and more work is needed to curb rapid population growth.
