Conditioning Factors for Fertility Decline in Bengal: History, Language Identity, and Openness to Innovations

POPULATION AND DEVELOPMENT REVIEW, Issue 4 2000
Alaka Malwade Basu
This article argues that looking solely for the immediate causes of reproductive change may distort our understanding of policy options by failing to take into account the historical and cultural factors that affect not only the impact of policies and programs but their very nature and existence. The article examines the historical origins and spread of "modern" ideas in Bangladesh and the state of West Bengal in India. It concludes that a colonial history in which education and modernization processes took hold very early among the elites in the larger Bengal region was paradoxically accompanied by a strong allegiance to the Bengali language. This strong sense of language identity has facilitated and reinforced the diffusion of modern ideas both within and between the two Bengali-speaking regions. Thus, to understand the fertility decline in Bangladesh, for example, one needs to look also at cultural boundaries. In this case, the cultural commonality through language facilitates the spread of new ideas across the two Bengals. In turn, the strong sense of language identity has facilitated mass mobilization more easily and intensely within the two Bengals. Shaped by these processes, Bangladesh and West Bengal today are more amenable to social change than many other parts of South Asia and the Middle East. [source]

Reproduction, Compositional Demography, and Economic Growth: Family Planning in England Long Before the Fertility Decline

POPULATION AND DEVELOPMENT REVIEW, Issue 1 2000
Simon Szreter
This article offers a radical reinterpretation of the chronology of control over reproduction in England's history. It argues that, as a result of post,World War II policy preoccupations, there has been too narrow a focus in the literature on the significance of reductions in marital fertility. In England's case this is conventionally dated to have occurred from 1876, long after the industrial revolution. With a wider angle focus on "reproduction," the historical evidence for England indicates that family planning began much earlier in the process of economic growth. Using a "compositional demography" approach, a novel social pattern of highly prudential, late marriage can be seen emerging among the bourgeoisie in the course of the eighteenth and early nineteenth centuries. There is also evidence for a more widespread resort to such prudential marriage throughout the population after 1816. When placed in this context, the reduction in national fertility indexes visible from 1876 can be seen as only a further phase, not a revolution, in the population's management of its reproduction.

Spatial Patterns of Fertility Transition in Indian Districts

POPULATION AND DEVELOPMENT REVIEW, Issue 4 2001
Christophe Z. Guilmoto
The article explores the dynamics of Indian fertility at the district level using a child-woman index developed from the four Indian censuses, 1961 to 1991. It employs statistical and geostatistical techniques to assess fertility change across districts and periods. Fertility decline is evident in every region, but sizable regional differentials exist. A cluster analysis of fertility profiles indicates that a clear spatial pattern of fertility in India has emerged and the pattern intensified because of the process of fertility decline. [source]

Erosion and Nutrient Loss on Sloping Land under Intense Cultivation in Southern Vietnam

GEOGRAPHICAL RESEARCH, Issue 1 2008
NGUYEN VAN DE
Abstract To help improve the well-being of the local people, a joint Vietnamese-UK team set out to establish a way of estimating soil and nutrient losses under different land management scenarios, using field data extrapolated through remote sensing and GIS, to obtain catchment-wide estimates of the impact of land cover change. Immigration from remote provinces to the Dong Phu District of Binh Phuóc Province, about 120 km north of Ho Chi Minh City, has led to disruption of soil surface stability on easily eroded clayey sandstones, creating rapid nutrient depletion that affects crop yields and siltation in the channel of the Rach Rat river downstream. The poor farmers of the areas see crop yields drop dramatically after two or three years of cultivation due to the fertility decline. Soil loss varies dramatically between wet season and dry season and with ground cover. Erosion bridge measurements showed a mean loss of 85.2 t ha,1 y,1 under cassava saplings with cashew nuts, 43.3 t ha,1 y,1 on uncultivated land and 41.7 t ha,1 y,1 under mature cassava. The rates of erosion were higher than those reported in many other parts of Vietnam, reflecting the high erodibility of the friable sandy soils on the steep side-slopes of the Rach Rat catchment. However, although the actual measurements provide better soil loss data than estimates based on the parameters of soil loss equations, a large number of measurement sites is needed to provide adequate coverage of the crop and slope combinations in this dissected terrain for good prediction using GIS and remote sensing.

Partnership and Parenthood in Post-transitional Societies: Will Specters Be Exorcised?

INTERNATIONAL JOURNAL OF JAPANESE SOCIOLOGY, Issue 1 2008
Nobutaka Fukuda
Abstract: The purpose of this article is to reconsider partnership and parenthood in post-transitional societies from the viewpoint of sociology. As is well known, after the end of the Baby Boom, albeit with variations in the tempo and the level, a considerable decline in fertility has occurred in industrialized countries. Furthermore, this decline has occurred in tandem with the transformation of partnership such as an increase in the number of cohabited couples. The causes and effects of this decline in fertility have hitherto been studied by social scientists such as economists and demographers. Although the family has been one of the main research interests for sociologists for a long while, the changes in partnership and fertility behavior in developed countries have not been sufficiently argued from the perspective of sociological theory on family. In this article, we will initially compare and contrast two changes in fertility patterns: the first of these is the fertility decline that occurred around the latter half of the nineteenth century; the second is the change that has been observed in industrialized countries since the second half of the 1960s. We will then discuss the difference between economic and ideational approaches in the explanation of partnership and fertility changes. Finally, we will examine the convergence and the divergence theories on family change. This article will conclude with an emphasis on the importance of the middle-range theories. [source]

Intercropping for the Improvement of Sorghum Yield, Soil Fertility and Striga Control in the Subsistence Agriculture Region of Tigray (Northern Ethiopia)

JOURNAL OF AGRONOMY AND CROP SCIENCE, Issue 1 2005
F. Reda
Abstract Striga hermonthica is a major biotic constraint in the dry and less fertile areas of northern Ethiopia. Emphasis is being placed on improved cropping systems to address the interrelated problems of Striga and soil fertility decline. The potential benefits of intercropping were investigated at two sites representing different environments for crop yield improvement, soil fertility maintenance and Striga control. Ten food legume and oilseed crop species were compared in inter-row arrangement with sorghum under non-fertilized conditions. In most cases, there was no significant negative impact of intercropping on sorghum growth and development. Among the intercrops, two cowpea varieties , cv. TVU 1977 OD and cv. Blackeye bean , produced the highest supplemental yield of up to 329 and 623 kg ha,1 grain and 608 and 1173 kg ha,1 biomass at Adibakel and Sheraro respectively. Treatment differences on Striga infestation and measured soil fertility indicators were not significant. Nevertheless, valuable grain and biomass obtained from the legume intercrops, without seriously compromising sorghum yield, could offer multiple benefits as a source of protein, additional income, feeds for animals and manure in the subsistence agriculture regions of northern Ethiopia.

Relay Cropping of Sorghum and Legume Shrubs for Crop Yield Improvement and Striga Control in the Subsistence Agriculture Region of Tigray (Northern Ethiopia)

JOURNAL OF AGRONOMY AND CROP SCIENCE, Issue 1 2005
F. Reda
Abstract Striga hermonthica is a major constraint in the subsistence agriculture regions of northern Ethiopia. Low soil fertility and overall environmental degradation has contributed to the build up of the parasitic weed infestation. Improved cropping systems have to be introduced to address the interrelated problems of Striga and soil fertility decline. Thus, relay cropping of sorghum with legume shrubs was investigated at two locations representing different environments. Results showed that the output of the improved cropping system was dependent on ecological endowments. Relay cropping led to significant improvement in yield at Sheraro, at the site with relatively better weather and soil conditions. The legume shrubs resulted in significantly lower sorghum yield in a dryland location (Adibakel). Overall Striga infestation declined over the 3-year period; however, treatment differences were not apparent. Among the two legume shrubs, Sesbania sesban was better adapted to the dryland areas. Relay cropping could provide a viable option for farmers in both types of environments that are characterized by accelerated decline in natural resource base. However, it could mean compromising the yield of non-fertilized sorghum in the interest of long-term benefits of low incidence of Striga and more rewarding crop enterprise in dry areas. [source]

Demography, Education, and Democracy: Global Trends and the Case of Iran

POPULATION AND DEVELOPMENT REVIEW, Issue 2 2010
Wolfgang Lutz
Reconstructions and projections of populations by age, sex, and educational attainment for 120 countries since 1970 are used to assess the global relationship between improvements in human capital and democracy. Democracy is measured by the Freedom House indicator of political rights. Similar to an earlier study on the effects of improving educational attainment on economic growth, the greater age detail of this new dataset resolves earlier ambiguities about the effect of improving education as assessed using a global set of national time series. The results show consistently strong effects of improving overall levels of educational attainment, of a narrowing gender gap in education, and of fertility declines and the subsequent changes in age structure on improvements in the democracy indicator. This global relationship is then applied to the Islamic Republic of Iran. Over the past two decades Iran has experienced the world's most rapid fertility decline associated with massive increases in female education. The results show that based on the experience of 120 countries since 1970, Iran has a high chance of significant movement toward more democracy over the following two decades. [source]

The Sex Ratio Transition in Asia

POPULATION AND DEVELOPMENT REVIEW, Issue 3 2009
Christophe Z. Guilmoto
This article adopts a comparative perspective to review the recent increase in the sex ratio at birth (SRB) across Asia. It first describes and compares the most recent birth statistics in Asia in order to identify commonalities in the gradual rise of SRBs observed from Armenia to South Korea. This comparison provides the basis for identifying specific transition patterns in the changes in SRBs. Their recent rise is then interpreted in a social and historical framework borrowed from fertility decline and based on three preconditions: access to sex-selection technology, preference for male births, and pressure from low fertility. On a broader plane, the process of growing imbalances in the sex composition of the population gives rise to a tragedy of the commons. This article indicates the factors that appear most likely to trigger a turnaround in this transitional demographic situation and to facilitate a return to biologically normal sex ratios in the future.

Spatial Patterns of Fertility Transition in Indian Districts

Fertility, Education, and Development: Evidence from India

POPULATION AND DEVELOPMENT REVIEW, Issue 1 2001
Jean Drèze
Fertility has declined significantly in many parts of India since the early 1980s. This article examines the determinants of fertility levels and fertility decline, using data on Indian districts for 1981 and 1991. The authors find that women's education and child mortality are the most important factors explaining fertility differences across the country and over time. Low levels of son preference also contribute to lower fertility. By contrast, general indicators of modernization and development such as urbanization, poverty reduction, and male literacy exhibit no significant association with fertility. En passant, the authors probe a subject of much confusion, the relation between fertility decline and gender bias. [source]

The Spread of Primary Schooling in sub-Saharan Africa: Implications for Fertility Change

POPULATION AND DEVELOPMENT REVIEW, Issue 3 2000
Cynthia B. Lloyd
In 1980 Caldwell hypothesized that the time of the onset of the fertility transition in developing countries would be linked with the achievement of "mass formal schooling." This article applies Demographic and Health Survey data to assess schooling patterns and trends for 23 sub-Saharan African countries, using the percentage of 15,19-year olds who have completed at least four years of schooling as an indicator of progress in education. As background to that assessment, the article includes a review of the sparse literature on the links between children's schooling and fertility decline. The analysis strongly supports Caldwell's hypothesis with empirical evidence of the much stronger negative relationship between fertility decline and grade 4 attainment in those countries that have attained mass-schooling levels than in those that have not yet achieved such levels.

Uncertain Aims and Tacit Negotiation: Birth Control Practices in Britain, 1925,50

POPULATION AND DEVELOPMENT REVIEW, Issue 2 2000
Kate Fisher
Evidence from oral history interviews is used to suggest the need to reevaluate our understanding of the dynamics of fertility decisions and behavior in the first half of the twentieth century. Those interviewed stressed their vague and haphazard approach to contraceptive use, in sharp contrast to the dominant depiction in studies of fertility decline that emphasize the degree to which individuals made deliberate and calculated choices about family size based on an assessment of the costs and benefits of childrearing. Details of individual contraceptive strategies elucidate the complexities of birth control behavior: couples, lacking explicit aims for family limitation, adopted diverse methods of birth control, using them for different reasons, at different times, with varying degrees of determination and confidence and frequently with very little direct discussion or planning. Explicit articulation of aims was not a necessary prerequisite of the spread of birth control; accepted gender roles meant that responsibilities and obligations emerged gradually and tacitly. As a result, nevertheless, low fertility was effectively achieved. [source]

Fertility transition in Ghana: looking back and looking forward

POPULATION, SPACE AND PLACE (PREVIOUSLY:-INT JOURNAL OF POPULATION GEOGRAPHY), Issue 6 2006
Samuel Agyei-Mensah
Abstract It is widely accepted that while the fertility transition is underway in sub-Saharan Africa, the pattern of change differs widely in both time and space. This paper examines the case of Ghana, regarded as the vanguard in the West African fertility transition. Based largely on analyses of Demographic and Health Survey data as well as localised studies, significant patterns emerge. One puzzling finding is that the increase in modern contraception usage has not kept pace with the declines in fertility. The paper suggests that this mismatch can be explained either by an increase in induced abortions, reduced exposure to sexual relations (perhaps due to HIV), or misreporting of contraceptive use. The paper also highlights the considerable geographical diversity in the ongoing fertility transition. The Northern region is still in the pre-transition stage, with little decline in fertility to date. In contrast, the pace of decline has been very rapid in the Greater Accra region. The factors underlying these patterns and the future trajectory of the fertility transition are discussed. It is argued that the fertility transition may be more leisurely in the near future than in the recent past. Among the factors working against future fertility decline are the stability in the infant mortality rate, the stall in fertility desires, and the low patronage of modern contraceptives especially in rural areas.

High infant and child mortality rates in Orissa: an assessment of major reasons

POPULATION, SPACE AND PLACE (PREVIOUSLY:-INT JOURNAL OF POPULATION GEOGRAPHY), Issue 3 2006
Jalandhar Pradhan
Abstract Infant and child mortality rates in Orissa are the highest among the Indian states. This is surprising, given other demographic indicators, such as the relatively rapid fertility decline and the quite high levels of antenatal care coverage in this state compared with other comparatively poor states. In this article, the macro- and micro-level determinants of high infant and child mortality are assessed using multivariate logistic regression analyses. The results demonstrate that the major contributors to the high infant and child mortality rates are the extremely low levels of health sector investments and the associated quality of care.

The demographic transition revisited as a global process

POPULATION, SPACE AND PLACE (PREVIOUSLY:-INT JOURNAL OF POPULATION GEOGRAPHY), Issue 1 2004
David S. Reher
Abstract With dramatic declines in fertility taking place throughout the world, it is increasingly important to understand the demographic transition as a global process. While this universality was a cornerstone of classic transition theories, for many decades it was largely neglected by experts because fertility in the developing world did not seem to follow the expected pattern. When comparing earlier and more recent transition experiences, important similarities and disparities can be seen. Everywhere mortality decline appears to have played a central role for fertility decline. The differences in the timing of the response of fertility to mortality decline, with very small gaps historically and prolonged ones in more recent transitions, plus the much more rapid decline in vital rates in many developing countries, constitute an important challenge to any general explanation of the process. The specific characteristics of recent transitions have led to decades of higher population growth rates, and promise to give way to much more rapid dynamics of population ageing in many countries. This may limit the ability of newcomers to take full advantage of the demographic transition for the social and economic modernisation of their societies. Copyright © 2004 John Wiley & Sons, Ltd.

Delayed Marriage and Very Low Fertility in Pacific Asia

POPULATION AND DEVELOPMENT REVIEW, Issue 3 2007
Gavin W. Jones
The general decline in fertility levels in Pacific Asia has in its vanguard countries where fertility rates are among the lowest in the world. A related trend is toward delayed marriage and nonmarriage. When prevalence of cohabitation in European countries is allowed for, levels of "effective singlehood" in many countries of Pacific Asia have run ahead of those in northern and western Europe. This raises questions about the extent to which delayed marriage has been implicated in fertility declines, and whether the same factors are leading both to delayed marriage and to lowered fertility within marriage. The article argues that involuntary nonmarriage is likely to be more common in Pacific Asia than in Western countries, and that resultant involuntary childlessness plays a substantial role in the low fertility rates currently observed.
