This paper reviews and synthesizes findings from scholarly work on linkages among rural household demographics, livelihoods and the environment. Using the livelihood approach as an organizing framework, we examine evidence on the multiple pathways linking environmental variables and the following demographic variables: Although the Married for same also bbw in Greenland draws on studies from the entire developing world, we find the majority of micro-level studies have been conducted in either marginal mountainous or arid or frontier environments, especially Amazonia.
Though the linkages are mediated by many complex and often context-specific factors, there is strong evidence that dependence on natural resources intensifies when households lose human and social capital through adult morbidity and mortality, and qualified evidence for the influence of environmental factors on household decision-making regarding fertility and migration.
Two decades of research on lifecycles and land-cover change at the farm level have yielded a number of insights about how households make use of different land-use and natural resource management strategies at different stages. A thread running throughout the review is the importance of managing risk through livelihood diversification, ensuring future income security, and culture-specific norms regarding appropriate and desirable activities and demographic responses.
Recommendations for future research are provided. One of the major areas of population-environment research in the past Fuck my wife in Uruara has focused on household-level population dynamics and their relationship, through livelihood strategies, to environmental change, particularly in rural areas of the developing world.
Studies have sought to go beyond the attribution of environmental degradation to high fertility and associated population increase. Instead, they have investigated the relationships among population variables household size, age and sex composition, fertility, on-farm population density, migration, and mortalitybiophysical variables forest cover, coastal mangroves, and soil qualityand natural resources firewood, timber, non-timber forest products, bushmeat and water in the Amazon Basin, Central America, Southeast Asia, East Asia, Oceania, and Africa e.
The research teams involved in these efforts have spanned the social and environmental sciences and have employed a wide range of methodologies, such as household surveys, participant observation, ground-level analyses of biophysical variables, and integration of remotely sensed imagery. This paper sets out to assess the lessons learned from and fruitful future directions in this large and growing body of research. A focus on household dynamics Fuck my wife in Uruara not imply that smallholders are necessarily the primary nor the ultimate agents of natural resource degradation or rural landscape change.
Industrial agriculture, commercial lumber and mining operations, and Fuck my wife in Uruara development schemes have arguably left a greater imprint on natural ecosystems throughout the developing world.
Further, the very presence of smallholders in biodiverse but agriculturally marginal environments rainforests, savannahs, coastlines is all too often the result of historically produced unequal land tenure regimes and international development policies strongly biased against the poor. In particular, a better understanding of household dynamics can help researchers and policy makers to understand how certain kinds of demographic behavior, especially fertility and migration, relate to livelihood strategies.
From the environmental perspective, household demographic dynamics can affect local environmental outcomes and resource dependence, and these dynamics may have significant repercussions for natural resource management and biodiversity conservation. Conversely, changes in the quality and quantity of natural resources can have important impacts on household fertility, morbidity, mortality, and migration. These multiple and multi-level dynamics between household demographics and environmental variables, mediated by contextual factors such as Fuck my wife in Uruara and regional environmental variability, policies, institutions and markets, makes this a complex area of study, but also one that is ripe for new discoveries and insights see also Zimmerer, The importance of these links is apparent in the outpouring of recent research on this topic.
Yet a comprehensive review of this diverse literature has been lacking. This paper therefore reviews some of the major strands of this research, examines common threads and lessons learned, and identifies some remaining research questions.
We begin with a discussion of the livelihood approach as an organizing framework and the importance of households as Fuck my wife in Uruara units.
Section 3 then describes how we selected the literature for review, and then has four subsections addressing in turn household fertility, morbidity and mortality, migration, and lifecycles in relationship to the environment and natural resources.
We offer some conclusions in Section 4. In this paper, we use the livelihood approach as an organizing framework and focus on demographic and Fuck my wife in Uruara changes as they play out in households.
In most rural areas of the developing world, the household is the basic unit of production and reproduction, 1 and the one at which most rural smallholders would say that critical decisions are made. The studies reviewed below therefore take the locally defined household as the unit of analysis.
In order to engage in these activities, households mobilize the assets at their disposal. A hallmark of the livelihood approach see Reardon and Vosti, ; Carney, ; Bebbington, ; Ellis, is its emphasis on the capabilities of the rural poor, based on the Fuck my wife in Uruara that even the poorest families hold wealth in at least some of the following categories:. The type and amount of each that a household holds is a function of past investment and accumulation strategies, which in turn are shaped by social, cultural, political and economic opportunities and constraints.
For example, a household may be considered wealthy in human capital if all adults have received a secondary education—access to which was Fuck my wife in Uruara in part by state investments in rural schools.
As households build up their stock of one type of asset, they Fuck my wife in Uruara change their stock of, or access to, other forms of capital. For example, a household that liquidates forest resources in order Prostitute in Phan Rang finance education is substituting natural capital for human capital, which may in turn yield employment opportunities that yield a steady stream of financial capital, which may then be depleted in order to invest in physical assets such as cattle.
The relationship that the household has with its environment, and by extension its impact on the environment, is mediated by its mobilization of these five forms of capital. The ability of the household to accumulate and utilize these forms of capital is further mediated by a number of factors. These include institutional factors e. The body of work we review below does much to elucidate the relationships among household demography, household capital, and the environment, most notably through time-intensive, qualitatively rich research typically conducted at the level of villages or small rural regions.
At this scale, contextual factors are very important for interpreting results. As the field moves towards more comparative work, we expect the development and testing of theories about the importance of context and interaction based on the divergent microlevel relationships found across study sites. Household population dynamics encompass several key variables: Given our focus on household-level demographics, we organize our survey of the related literature around these variables, rather than, say, by region, resource type, or bioclimatic zone.
This section is therefore organized into subsections addressing the relationships between forms of environmental change and fertility, morbidity and mortality, migration, and lifecycles. For each, we review recent scholarly work identified through searches of the Science Citation Index and the Population-Environment Research Network PERN eLibrary, as well as book chapters and monographs known to the co-authors, in which the researchers focus on households and give specific treatment to both demographic and environmental variables in their studies.
This paper is thus a research synthesis rather than a meta-analysis. The multiplicity of independent and dependent variables would make a meta-analysis impractical, and a research synthesis allows us to bring together strands of research to advance theory in a more flexible and inclusive way.
One popular theory to explain the existence of sustained high fertility in the face of declining Fuck my wife in Uruara resources is the vicious circle model VCM. High fertility then contributes to population growth which further increases demands for food and resources from an essentially static resource base; the declining per capita resource base reinforces poverty through soil fertility loss, declining yields, and poor environmental sanitation.
Finally, poverty, in turn, contributes to land degradation by increasing incentives for short-term exploitation versus long-term stewardship and because poor farmers lack access to costly fertilizers and appropriate technologies.
Seen from the perspective of the livelihoods framework, the VCM would suggest that households without access to other forms of capital seek to build their human capital and social capital through the marriage and migration of children in order to better exploit natural capital. Of particular relevance here are the studies they Fuck my wife in Uruara that examine the relationship between fertility and farm size, cattle, and access to natural resources.
The VCM would predict that all of these relationships are negative, with poorer households having higher Fuck my wife in Uruara. We summarize here the key conclusions Fuck my wife in Uruara the studies Sutherland et al.
Farm size and Fuck my wife in Uruara tenure are key indicators of the physical capital of households. In contrast to the VCM, the relationship between this key productive asset and fertility related to human capital is expected to be positive under the land-labor-demand hypothesis advanced by Stokes and Schutjer They postulate that a larger farm size creates a demand for children as labor to keep land in production Women online andhra web cam to retain use rights.
Alternatively, it has also been proposed that the effects of land tenure can counteract the relationship Fuck my wife in Uruara farm Women who wanna fuck in Chumbicha and family size. Under this land-security hypothesis, land tenure security creates economic security that lowers the need to invest in large numbers of children Stokes and Schutjer, Greater security is associated with higher living standards, access to health care, and greater educational opportunities, all of which promote lower fertility.
Studies in the Philippines, Egypt, Ecuador, Iran, India and Mexico provide evidence for the negative relationship between tenure security and fertility Hiday, ; DeVaney and Sanchez, ; Vlasoff and Vlasoff,Schutjer et al.
In frontier areas, he argues, land is abundantly available, and therefore parents opt for higher fertility in Fuck my wife in Uruara that Fuck my wife in Uruara will be available for their children. As the Sexy singles in Talas becomes settled it is expected that fertility would decline in response to the perceived scarcity of land to settle.
This hypothesis has not been tested with household-level data, but macro-level studies have supported this hypothesis in Thailand, the United States and Brazil Easterlin, ; Merrick, ; VanLandingham and Hirschman, Cattle are second only to land as an Fuck my wife in Uruara form of physical capital for rural families worldwide. But unlike land, Fuck my wife in Uruara are portable assets that are easily transported and traded; further, they provide a stream of income from dairy products; and they represent a status symbol Loker, ; Faris, Fuck my wife in Uruara grazing requires little labor and they can be sustained on land that is too poor for crops.
Thus, it could be expected that cattle, like land, might factor into fertility decision making. For example, cattle could be seen as a retirement account Fuck my wife in Uruara could reduce demand for children. However, Perz asserts at least for the Brazilian Amazon that cattle tend to be acquired later in life, after child bearing is completed, when households have acquired sufficient capital to invest in cattle.
In this hypothesis, children are in demand by parents because they provide labor needed for early agricultural production and later, when they migrate out, remittances needed for acquisition of cattle.
More recent work continues to debate the relationships between farm size, farm tenure or cattle and fertility. Ownership of cattle was strongly and positively associated with family size. Here again, reverse causality is more likely, since larger families are presumably older and therefore more likely to have accumulated the resources necessary for cattle Fuck my wife in Uruara. By using longitudinal data they were able to follow families and plots over time and analytically describe the relationship between landholdings and fertility.
The data support the land security hypothesis Stokes and Schutjer,with women in households with secure title having two-thirds fewer Fuck my wife in Uruara then those without such titles. Consistent with the VCM hypothesis, women on the smallest farms in had more than double the number of children than did women on the largest farms.
Large cattle and coffee holdings during the time period were associated with lower fertility. Generally their findings confirm hypothesized links between poverty and fertility: Access to fuelwood and water are everyday challenges for most rural dwellers. In rural areas these tend to be collected from communal lands, such as forests and rivers.
Gathering these resources is often left to women and children. Dasgupta hypothesizes that as these resources become Fuck my wife in Uruara each additional child provides a marginal benefit through his or her labor. This suggests that resource dependency will result in higher fertility. There is empirical evidence supporting this hypothesis from Pakistan, Nepal, and South Africa Aggarwal et al. Two recent studies have focused on the importance of collecting open access resources for fertility preferences and behaviors, showing the value of human capital children as a complement to natural capital open access water, fodder, and fuelwood.
Furthermore, women in households where the time to collect firewood had increased by more than an hour Fuck my wife in Uruara the three years prior to the initial survey were more likely to have had a pregnancy in the three years after that survey. Another study, in Pakistan, found a similarly positive effect of firewood scarcity on the probability of a birth in the past five years - a relationship that varies across regions of the country, and may be partially explained by the evolution of property rights in different provinces Filmer and Pritchett, Much of the research on fertility-livelihood-environment linkages is predicated on the notion that childbearing decisions are largely an economic calculus, and that in rural subsistence-based Fuck my wife in Uruara the returns to childbearing are higher than the net costs.
For example, evidence from Zambia suggests that the age at which children change from net consumers to net producers is about age 12 Barrett and Browne, The theoretical foundation of Fuck my wife in Uruara of the work reviewed in this subsection derives from the household model of fertility Becker ; Becker and Lewis This model has provided useful Fuck my wife in Uruara for empirical work in terms of clarifying the various interdependent and simultaneous decisions facing households in terms of human capital number and quality of childrenproduction, consumption and labor market participation.
This approach helps to identify how households choose different livelihood strategies, given their asset endowments and preferences.
This said, however, the household modeling approach also has several limitations. Among them, the assumption of a unitary household may be misleading in several contexts where different members of the household have divergent preferences regarding family size given the asymmetry in distribution of costs and benefits of children coupled with asymmetric bargaining power.
The household model also fails to take into account the complexity of social, political, cultural and religious context of fertility. A household in a Fuck my wife in Uruara social context may therefore choose to have high fertility because of prevailing social and cultural norms. Since these norms change slowly, there exists the potential for high fertility to be sustained even in the context of a declining resource base.
The major focus of population policies in the developing world is on fertility and family planning. There have also been recent efforts to develop community-based population-environment programs that marry biodiversity and Fuck my wife in Uruara resource conservation with family planning and reproductive health programs Grandia,
