Full textAbstract:
Cultural, ecological, familial and physiological factors consistently influence fertility behaviours, however, the proximate psychological mechanisms underlying fertility decisions in humans are poorly understood. Understanding the psychological mechanisms underlying human fertility may illuminate the final processes by which some of these known predictors have their influence. To date, research into the psychological mechanisms underlying fertility has been fragmented. Aspects of reproductive psychology have been examined by researchers in a range of fields, but the findings have not been systematically integrated in one review. We provide such a review, examining current theories and research on psychological mechanisms of fertility. We examine the methods and populations used in the research, as well as the disciplines and theoretical perspectives from which the work has come. Much of the work that has been done to date is methodologically limited to examining correlations between ecological, social and economic factors and fertility. We propose, and support with examples, the use of experimental methods to differentiate causal factors from correlates. We also discuss weaknesses in the experimental research, including limited work with non-WEIRD (western, educated, industrialized, rich and democratic) populations.

Globalization is the phenomenon that has made quite a loud statement about itself during the last decades of the 20th century and found its representation in the formation of global economic, financial, cultural, legal, and political areas. Having been the conglomerate of various national states for thousands of years, the world’s social, economic, ecological, cultural space is now transforming into space without borders. The formation of global economic relations, ecological, demographic challenges can’t be solved individually, with local measures and means. In the second half of the 20th century, the world faced global problems and crises (ecological, demographic, reorganization of the economic and political world order), which have become the challenges that can’t be solved with the help of local actions. The global community is forced to raise issues about the ecologization of the entire industrial activity taking into account its consequences at all levels: local, national, and international. That’s what common threats and problems require. The sustainable development paradigm requires both reviewing and changing the “human-nature” system and realizing the necessity of preserving nature for ensuring the existence of the next generations. Sustainable development is to provide the transfer to a new economic type – the green economy, which requires significant investments, particularly in the renewable-energy industry, industrial waste treatment, restoration of soil fertility, preservation of forests.

Full textAbstract:
The population problem has always been a fundamental, overall and strategic issue faced by the human society. While China’s family planning policy has promoted China’s economic development and social progress, the “two-child” policy failed to receive satisfactory result. Confronted by China’s low fertility rate, efforts must be done from many aspects to spur population growth: establish the National Population Security Council, strengthen the selection and appointment of population policy makers, strengthen the family values, adopt incentive measures to increase fertility, and so on. The “two-child” policy has been carried out for more than three years, and the policy is still facing the test of time. China’s “two-child” policy is still a transitional policy, and the final solution will be to abandon birth control.

Full textAbstract:
The article is devoted to the characteristics of trends in the accumulation of human capital in Ukraine over the period of independence. The purpose of the article is to study the key factors that caused the existing trends in the accumulation of human capital during the period of independence of Ukraine. The novelty of the study lies in the application of a systematic approach to establishing the influence of the main factors on the accumulation of human capital in the country over the past twenty years.The expediency of the study of factors that directly affect the course of the processes of accumulating human capital at regional and national levels has been substantiated. The relationship between the quality of life of the population, the socio-economic development of the country and the volume of human capital has been established.The conditions (the number and structure of the current population; the number of live births and deaths per year and per 1000 people of the population; natural population decline, the number of marriages registered per year; total annual fertility rate, average life expectancy at birth), typical for Ukraine at the time of its independence in 1991, in the dynamics of demographic and socio-economic processes in Ukraine during the period of its independence have been analyzed.The tendencies that have been achieved by Ukraine in the nineteen years of independence in the field of socio-economic development, such as: the annual decline in the population and the total fertility rate; an increase in the mortality rate of the population; drop in GDP per capita and human development index are established. The key aspects of stabilizing the situation in the field of human capital accumulation in Ukraine, which should be based on the intensive development of the business environment, improving the quality of education, and comprehensive social protection of the population, have been substantiated.

Full textAbstract:
The European research on iron has traditionally focused on the technical and economic aspects of iron production, However, a view of metal working in a wider regional context shows that it is generally entrenched in symbolic meaning and ritual activity. In this paper, the author employs four ethnographic case studies to show the importance of symbolic and ritual aspects of iron working and how these are intertwined with technological factors. What comes across are also the metaphorical links between pottery vessels, food, and furnaces used to produce iron. When looking at the European material, one can discern the same associations in the ftnds of cauldrons used for offerings of food as in the finds of cauldrons used for offerings of iron, such as iron weapons. The former are placed in a context ofnurturing and human reproduction, while the latter are placed in a context of destruction. This indicates the ambiguity of iron as associated with nourishment-fertility and with destruction and death

Full textAbstract:
AbstractThe efforts of rural communities around the world to survive in the face of economic and demographic decline dramatise the bio-cultural processes on which human regeneration routinely depends. This paper explores the very conspicuous symbolic aspects of regeneration in a village in Catalonia, Spain, and traces the long term physical and material processes that underlie them. Scrutiny of two different festivals reveals a passionate concern to renegotiate deeply fractured generational relationships. Having exported its fertility to the towns and cities, the community is now working to incorporate newcomers and devise new livelihoods. Public rituals have done much to sustain these efforts at regeneration, but how they may resist the “sterile growth” of Mieres as a village of mostly empty second homes is a provocative new issue.

Full textAbstract:
Dependence of damage estimates upon assumptions of economic growth and technological development Greater economic growth could, by increasing emissions, lead to greater damages from climate change. On the other hand, by increasing wealth and advancing technological development and human capital, economic growth would also increase a society's adaptive capacity and reduce those damages. Although analyses of the impacts (or damages) of climate change generally incorporate economic growth into the emissions and climate change scenarios that they use as inputs, these analyses do not adequately account for the increase in adaptive capacity resulting from that very growth. Because of this inconsistency, these analyses generally tend to overstate impacts. For instance, the average GDP per capita for developing countries in 2100 is projected to be $11,000 (in 1990 US$, at market exchange rates) under A2, the slowest economic growth scenario, and $66,500 under A1, the scenario with both the greatest economic growth and largest climate change. By comparison, in 1990 the GDP per capita for Greece, for example, was $8,300 while Switzerland, the country with the highest income level at that time, had a GDP per capita of $34,000. Based on historical experience, one should expect that at the high levels of GDP per capita projected by the IPCC scenarios in 2100, wealth-driven increases in adaptive capacity alone should virtually eliminate damages from many climate-sensitive hazards, e.g., malaria and hunger, whether or not these damages are caused by climate change. Current damage estimates are inflated further because they usually do not adequately account for secular (time-dependent) improvements in technology that, if history is any guide, ought to occur in the future unrelated to economic development. A compelling argument for reducing greenhouse gases is that it would help developing countries cope with climate change. It is asserted that they need this help because their adaptive capacity is weak. Although often true today, this assertion becomes increasingly invalid in the future if developing countries become wealthier and more technologically advanced, per the IPCC's scenarios. Damage assessments frequently overlook this. Are scenario storylines internally consistent in light of historical experience? Regardless of whether the economic growth assumptions used in the IPCC scenarios are justified, their specifications regarding the relationship between wealth and technological ability are, in general, inconsistent with the lessons of economic history. They assume that the less wealthy societies depicted by the B1 and B2 scenarios would have greater environmental protection and employ cleaner and more efficient technologies than the wealthier society characterized by the A1F1 scenario. This contradicts general experience in the real world, where richer countries usually have cleaner technologies. Under the IPCC scenarios, the richer A1 world has the same population as the poorer B1 world, but in fact total fertility rates — a key determinant of population growth rates — are, by and large, lower for richer nations and, over time, have dropped for any given level of GDP per capita (Goklany 2001a). Merits of reallocating expenditures from mitigation to international development Halting climate change at its 1990 level would annually cost substantially more than the $165 billion estimated for the minimally-effective Kyoto Protocol. According to DEFRA-sponsored studies, in 2085, which is at the limit of the foreseeable future, such a halt would reduce the total global population at risk (PAR) due to both climate change and non-climate-change-related causes by 3 percent for malaria, 21 percent for hunger, and 86 percent for coastal flooding, although the total PAR for water shortage might well increase. The benefits associated with halting climate change — and more — can be obtained more economically through “focused adaptation”, i.e., activities focused on reducing vulnerabilities to the above noted climate-sensitive hazards, or through broadly advancing sustainable development in developing countries by meeting the Millennium Development Goals (MDGs) by 2015. In fact, such efforts, which together could annually cost donor countries $150 billion according to UN Millennium Project and World Health Organization studies, should reduce global malaria, hunger, poverty, and lack of access to safe water and sanitation by 50 percent (each); reduce child and maternal mortality by at least 66 percent; provide universal primary education; and reverse growth in AIDS/HIV, and other major diseases. These numbers also indicate that no matter how important climate change might be in this century, for the next several decades it would be far more beneficial for human well-being, especially in developing countries, to deal with non-climate change related factors. Not only would either focused adaptation or adherence to the MDGs provide greater benefits at lesser costs through the foreseeable future than would any emission reduction scheme, they would help solve today's urgent problems sooner and more certainly. Equally important, they would also increase the ability to deal with tomorrow's problems, whether they are caused by climate change or other factors. None of these claims can be reasonably made on behalf of any mitigation scheme today. Accordingly, over the next few decades the focus of climate policy should be to: (a) broadly advance sustainable development, particularly in developing countries since that would generally enhance their adaptive capacity to cope with the many urgent problems they currently face, including many that are climate-sensitive, (b) specifically reduce vulnerabilities to climate-sensitive problems that are urgent today and might be exacerbated by future climate change, and (c) implement “no-regret” emission reduction measures, while (d) concurrently striving to expand the universe of no-regret options through research and development to increase the variety and cost-effectiveness of available mitigation options. Ancillary benefits associated with greenhouse gas (GHG) reductions Some GHG emission control options might provide substantial co-benefits by concurrently reducing problems not directly caused by climate change (e.g., air pollution or lack of sustained economic growth, especially in developing countries). However, in both these instances, the same, or greater, level of co-benefits can be obtained more economically by directly attacking the specific (non-climate change related) problems rather than indirectly through greenhouse gas control. On the other hand, a direct assault on the numerous climate-sensitive hurdles to sustainable development (e.g., hunger, malaria, and many natural disasters) would, as indicated, provide greater benefits more cost-effectively than would efforts to mitigate climate change.

The purpose of the work is to identify the problems of forming the human potential of rural areas of the country and substantiate strategic guidelines and promising areas and means of solving them to ensure its growth and sustainable development. Methodological basis of the article is the use of modern theoretical provisions of the economy of the national economy, rural territories, the reproduction of human potential; General scientific and special methods of knowledge: demographic, statistical-economic, economic-mathematical, graphic. Results of work. It is determined that the human potential of rural areas of Ukraine is formed by demographic factors, employment and employment, income level, quality and social and environmental conditions of life. However, it is the narrowed natural reproduction, high unemployment and low incomes of rural residents that cause its deterioration and degradation. It is found that these and other problems should be solved by implementing state programs to support rural fertility, developing alternative activities and increasing employment, social and environmental development of rural areas. The field of application of results. The conclusions and suggestions of the article can be used by local governments, rural communities, public organizations, charitable foundations in solving problems of human development in rural areas, educational and scientific institutions in educational and scientific activities. Conclusions. Financial sources for the implementation of proposals can be monetary and other resources of agricultural enterprises, rural residents, rural communities, targeted state programs, public organizations and charitable foundations. Public-private partnership, social responsibility, social innovation, information and digital technologies should be used as tools for achieving these goals. When determining priorities for implementing these measures in practice, it is necessary to take into account the specifics of each locality, the region where they are located, as well as the decisions of rural communities. This will contribute to the revival of rural areas, increase the prestige of rural life, preserve the rural way of life, expand the reproduction of human capital and personal growth of human potential.

Full textAbstract:
Health is an important aspect of human life. In general terms, better health status of individuals reflects reduced illnesses, low level of morbidity, and less burden of disease in a given population. It is widely recognised that improved health not only lowers mortality, morbidity and level of fertility, but also contributes to increased productivity and regular school attendance of children as a result of fewer work days lost due to illness, which in turn have implications for economic and social well-being of the population at large. Hence investing in health is vital for promoting human resource development and economic growth in a country [World Bank (1993)]. A view of Pakistan’s health profile indicates that the sector has expanded considerably in terms of physical infrastructure and its manpower in both the public and private sector. This has contributed to some improvement in selected health status indicators over the years. However, the public health care delivery system has been inadequate in meeting the needs of the fast growing population and in filtering down its benefits to the gross-root level. As such, Pakistan still has one of the highest rates of infant and child mortality, total fertility and maternal mortality when compared with many other countries in the Asian region [UNDP (2000)]. Due to low priority given to social sector development in the past and low budgetary allocations made to the health sector, the evidence shows that mortality and morbidity indices have not reduced to the desired level and large gaps remain in the quality of care indicators, especially in rural areas [Federal Bureau of Statistics (2000)].

The article notes that humanity has realized the need for changes in the social paradigm, in particular in the context of the transition to sustainable development. In this regard, the theoretical and methodological aspects of social safety in the context of sustainable development are investigated; reveals the essence of the category "social safety" and its components. It is emphasized that social safety, which covers all spheres of human life – social, economic, environmental and guarantees the safety of society from various types of threats. The most important factors affecting the provision of social safety are also considered, the leading place among which is occupied by those that are of a socio-economic nature. These factors ensure the avoidance of social deformations and imbalances in human life, the infringement of his vital interests. An assessment is made of the situation in Ukraine regarding social safety, and in this regard, possible threats are identified. Among these threats, it is especially noted that Ukraine stands out for its low birth rates and a high mortality rate, that is, it has a significant excess of mortality over fertility. An important statement is that the formation of social safety is not only the overcoming of existing problems and threats, but, above all, the formation of tools to prevent and protect society from their onset. Considerable attention is paid to the substantiation of approaches to the formation in our country of conditions for ensuring social safety, taking into account the principles of sustainable development of human civilization and its scientifically sound balance. Among these principles are noted – the acquisition of new knowledge by employees; priority development of the social sphere; implementation of an active regulatory policy of the state to ensure social guarantees, which should take into account the concentration of state resources on the satisfaction of priority social interests; creating an effective mechanism for achieving social safety. All this should contribute to sustainable socio-economic development.

Full textAbstract:
Mycotoxins are ubiquitous and unavoidable harmful fungal products with the ability to cause disease in both animals and humans, and are found in almost all types of foods, with a greater prevalence in hot humid environments. These mycotoxins vary greatly in structure and biochemical effects; therefore, by better understanding the toxicological and pathological aspects of mycotoxins, we can be better equipped to fight the diseases, as well as the biological and economic devastations, they induce. Multiple studies point to the association between a recent increase in male infertility and the increased occurrence of these mycotoxins in the environment. Furthermore, understanding how mycotoxins may induce an accumulation of epimutations during parental lifetimes can shed light on their implications with respect to fertility and reproductive efficiency. By acknowledging the diversity of mycotoxin molecular function and mode of action, this review aims to address the current limited knowledge on the effects of these chemicals on spermatogenesis and the various endocrine and epigenetics patterns associated with their disruptions.

Full textAbstract:
The purpose of the article is to study the economic, social and environmental features of the use of land resources of agricultural enterprises, which is one of the determining factors of economic development and environmental safety of the state. Optimization of the use of land resources in ecological, economic and social aspects is the basis for a favourable territorial environment of natural landscapes. The goal of the article is to study the economic efficiency of the use of land resources in modern conditions, their social and environmental basis. Methodology. To write the article, methods of analysis, comparison, and generalization of research results, economic, statistical and graphic methods have been used. It is clear that research on the efficiency of the use of land resources in agricultural enterprises is a complex and lengthy process. Taking this into account, it is impossible to identify a single indicator that can fully reflect the level of efficiency in the use of land resources. For a more complete characterization of the specified process, a system of both natural and value indicators should be used. Results. According to the results of the study, it has been established that the practice of land use and the state of study of certain problems require further study of the prerequisites for the development of processes of soil degradation caused by the main factors: human economic activity, climatic, relief and ground conditions. Attention is drawn to the efficiency of the use of land resources in agricultural enterprises of Ukraine; the distribution of enterprises in Ukraine is carried out by the size of agricultural land. The role of state financing of enterprises in the sector of agro-industrial development is analysed, and the state of financing of programs to support agro-industrial production in 2019 is considered. The social aspects of land use in Ukraine are processed; they are focused on the quality of food, ensuring the welfare of the population and landscaping of rural municipalities. The program of support of the agro-industrial production sector by providing loans to agrarians has been investigated: in particular, it is planned to allocate 1,200,000,000 UAH for a programme to reduce the cost of loans to enterprises engaged in all types of agricultural activities. Practical implications. Since the practice of managing agricultural enterprises in market conditions shows that the most important thing is not the availability of land resources but the efficiency of using its potential; therefore, the need to create a reliable economic mechanism that will ensure the effective use of land resources and preserve their fertility is a priority. The breadth and versatility of land problems, their connection and dependence on socio-economic, political and environmental factors necessitate further research on this issue.

Full textAbstract:
Livestock play a very important role in the agriculture of most developing countries, accounting on average for an estimated half of agricultural output through their direct and indirect contributions. Major functions include: production of human-edible food from human-inedible forages, crop residues and by-products; concentrating nutrients, thus increasing the quality of food and producing high-value products for sale; serving as a source of savings and income for producers who lack access to banks or credit; recycling plant nutrients and improving soil fertility; serving as a food reserve; and providing draft power. Crop-livestock systems are in general more stable and more productive than cropping systems alone. A perceived problem due to livestock is overgrazing and environmental degradation, but these are usually the result of human mismanagement of the animals. Traditional pastoral systems can be not only persistent, but ecologically sound. The currently observed problems associated with pastoral systems in arid and semi-arid lands are more likely to result from breakdown of traditional management practices due to human population increase and external intervention or social changes, or from abiotic factors such as climatic variation, than from flaws in the traditional system. Research and development programs can increase the contributions of animals to the well-being of their owners and to the economies of developing countries. Some areas with high potential include: evaluation of local genetic resources; assessment of feed resources and design of economical, efficient supplementation strategies; and reduction of costs of disease control by development of multivalent vaccines. There are opportunities for large increases in efficiency of resource utilization and animal productivity. However, a more thorough understanding of social and economic as well as biological aspects of production systems than has usually existed in development projects is essential for interventions, where they are indicated, to be effective. Key words: Food quality, efficiency, production systems, sustainability, genetic resources, animal traction

Full textAbstract:
Historically, research in India on early mammalian development had only begun, rather modestly, in the last century, unlike the USA and UK. In India, initial studies were on gonadal and reproductive tissue development and function and they were limited to anatomical and histological characterization. This was followed by research on fertility regulation and contraception. Since the 1960s, a major initiative took place regarding endocrine biochemistry and the use of antifertility agents in inhibiting gonadal function and early development. Post-independence, the Indian government´s funding support enabled universities and institutions to embark on various research disciplines in biology but with no particular emphasis on developmental biology per se. Subsequently, India made significant progress in the area of mammalian reproduction and development, but not specifically in the core aspects of developmental biology. Reasons for this could be due to the nation’s compulsion to invest and embark on socio-economic and infrastructure development and on research involving family planning methods for reversible-affordable contraceptives to curtail population growth. With regard to the latter, biologists were involved in hormone-based contraception research. During this pursuit, insights were achieved into basic aspects of the development of gonads, gametes and embryos. Notwithstanding this, in the post-1980s through to the present time, Indian scientists have contributed to (i) the understanding of the cellular and molecular regulation of early development, (ii) developing genetically modified mouse models, (iii) using assisted reproductive technologies, generating mammalian progeny, including humans and (iv) deriving pluripotent stem cell lines for developmental studies. This article provides a perspective on the past and current status of early mammalian development research in India.

Full textAbstract:
Of the renewable resources of The Biosphere, agricultural land, including its water resources, is very high among the most important, because it is elemental for human and domestic-animal life. The stability and sustained fertility of the soil largely depend on both prevailing soil–climate conditions and on anthropogenic influences.There are strict limits to the human interference which soil substrates, ground, soil, and surface water, flora, fauna, and microorganisms, can tolerate under moderate, let alone subtropical and tropical, soil–climate conditions. Economic, social, and aesthetic, yield of agricultural resources is limited even where economically and technically optimal use is made of capital and labour. A ‘maximum sustainable yield’ varies as a function of the soil–climate location, the established land-use system, and the technology applied, but only as long as this yield is not exceeded is the enduring availability of the resource ensured.With the demand for land and energy to produce food and agricultural raw materials rising throughout the world, per caput food production continuing to fall (especially in Africa), and the cultivated area per caput declining worldwide, the urgent question for the long term is how to preserve the natural resources of water, soil, and vegetation cover, and how to arrest desertification, deforestation, salinization, soil degradation, and soil erosion.These reflections centre on the call for farming systems which are suited to given locations and do no harm to the environment, and also for sustainability of agricultural production—two aspects which have been badly neglected in the past. The necessary simultaneous tasks of developing farming systems and preserving resources, can be tackled only in relation to specific locations and in a conducive development ‘climate’, where appropriate general conditions prevail. As a rule, the microeconomic development options for coping with these tasks can be improved only at a supra-farm and community level, and require new, environmentally oriented national agricultural and rural development policies.

Full textAbstract:
The paper presents an outline of the relationship between anthropology and demography, sometimes depicted as "long, tortured, often ambivalent, and sometimes passionate." Although early anthropologists (primarily British social anthropologists) routinely made use of demographic data, especially in their studies of kinship, the two disciplines gradually drifted away from each other. The re-approachment took place from 1960s, and the last fifteen years saw more intensive cooperation and more insights about possible mutual benefits that could be achieved through combining of methodologies and revision of some theoretical assumptions, primarily through anthropological demography. As summarized by Laura Bernardi and Inge Hutter, "Anthropological demography is a specialty within demography that uses anthropological theory and methods to provide a better understanding of demographic phenomena in current and past populations. Its genesis and ongoing growth lies at the intersection of demography and socio-cultural anthropology and with their efforts to understand population processes: mainly fertility, migration, and mortality. Both disciplines share a common research subject, namely human populations, and they focus on mutually complementary aspects" (2007: 541). In the first part of the paper, the author presents some general considerations, like the one that "demography is one of the best understood and predictable parts of human behavior, even if demographers still find themselves unable to predict accurately when parameters will change in interesting ways, such as the ?the baby boom? or the shift to later childbeanng in the 1970s and 1980s North America" (Howell, 1986: 219). Nancy Howell also noted the importance of demographic anthropology, because, in her words "if we knew, reliably, the birth and death probability schedules of particular populations, we would know a great deal about their size, age composition, growth rate. And with just a little more information we would know a great deal more such as household and family composition, economic organization, social problems, and something of the political structure. It we knew the schedules for populations in general and could correlate the schedules with the causes, genetic or environmental, that produce them, we would know a great deal about the possible range of human social structure" (Howell, 1986: 219). In the second part of the paper, the author discusses several examples of interplay between anthropology and demography. One of them is Patrick Heady?s study of the shift in ritual patterns, which combines elements of some "classical" anthropological topics (Mauss?s theory of gift exchange and L?vi-Strauss?s concept of kinship) with his own field research in the Carnian Alps. "By marrying and raising children, parents participate in a system of gift-exchange in which the gifts in question are human lives, and the parties to the exchange are the kinship groups recognized in the society concerned. Fertility reflects the attitudes of prospective parents to their place in the existing system of reproductive exchange, and the relationships of cooperation and authority which it implies - as well as their confidence in the system?s continuing viability. It is shown that this view is compatible with earlier ideas about self-regulating population systems - and that changing economic circumstances are an important source of discrepancy between existing exchange systems and the attitudes and expectations of prospective parents" (Heady, 2007: 465). The paper concludes with the discussion of the directions in which relationship between these two disciplines can proceed. Some of the epistemological issues are mentioned, as well as a need to apply different theoretical perspectives to better understand demographic behavior (especially in Europe) and to better understand certain cultural components that shape this behavior. In order to achieve this, most of the scholars whose works are discussed in this paper emphasize "the need for a holistic approach to data collection and the added value of triangulating quantitative and qualitative analyses" (Bernardi, Hutter, 2007: 541).

The goal of this study of community based waste management and utilization was to reduce the major negative impact of environment and health hazards created by improperly managed waste mainly focusing on livestock production system of Bangladesh. The waste amounted 4,78,220 kg annually managed by the community contribute to significant role regarding human and livestock health, sanitation, economic as well as environmental aspects. In terms of economic, the Chadkarim community could earn net benefit of Tk. 2,70,146 in 2012 by selling waste by-products, major earnings come from 95,644 kg of organic fertilizer producing amounting Tk. 1,37,546 The global environmental perspective is to reduce livestock-induced, land-based pollution and environmental degradation. One of the major costs of running an agricultural farm can include buying nitrogen in the form of anhydrous ammonia to fertilize crops. But there are other agricultural costs associated with nitrogen, especially when the nitrogen in livestock waste produces pungent and potentially harmful ammonia emissions. To get expected production and to trap optimum socio-economic benefit from livestock rearing, waste must be managed in proper ways through a community based biogas producing approach of waste management to have sustainable environment. During one year community managed 4,78,220 kg degradable waste and produced about 17,216 m3 of biogas and utilized that gas for cooking and electricity generation. The notable benefits come from womens saved time and money. The 200 households at the community in one year have saved 15,881 working days through reduced time required for managing of fuel and cooking purposes. Most of the saved time is being utilized for household tasks and for education of the children. This is one of the greatest contribution to the nation.

SummaryRecent changes in vital rates in Fiji suggest that the Melanesian (MF) component of the population is growing faster than the Indian (IF) component, thus reversing a long-standing demographic trend.Patterns of family building were studied in the respondent families of 302 MF and 324 IF children at school in the capital, Suva. Melanesian families were larger than IF families, even when corrected for differences in maternal age and social class. Particularly among IF families, there was a significant effect of social class on family size, higher status families having fewer children. Among all groups there was evidence of a secular trend to earlier childbearing and, less clearly, to an earlier cessation of childbearing. Among both races age-specific fertility levels were similar in younger age-groups, but older IF mothers showed significantly lower fertility.It is suggested that among IF families, who form a more urbanized and commercially/industrially oriented segment of the Fijian population, two factors may account for the reduction in fertility: (i) pressure to limit population growth in the interests of racial harmony; and (ii) economic pressure resulting in a demographic transition. The latter suggestion is supported by the fact that the greatest decrease in fertility occurs among high status families. Among MFs the reduction in fertility has been less, due probably to the absence of a ‘racial harmony’ incentive and also to a lesser economic stimulus.

Data on L. hardjo infection of dairy cows in the world pint out its important role in the occurrence of health and economic problem. L. interrogans serotype hardjo has been described as the cause of miscarriages, stillbirts, or the birhs of poorly vital calves, agalactia, mastitis, and low fertility in cows. Two L. hardjo genotypes have been identified in cows, namely, hardjopraitno and hardjobovis. Serological investigations have established a drastic increase in this leptospiral infection in cows. L. hardjo has become adapted to cattle as the primary host, so that an infection is maintained in herds and becomes deeply rooted because of the permanent presence of the source of infection. It was believed that sheep were accidental hosts, but the latest research suggest that they are yet another, transitory, host for maintining this leptospira serotype. L. hardjo is also important from the aspect of human health, especially of persons who are professionally exposed to this infection. L. hardjo infection is detected using serological tests and by proving the presence of leptospira. The medicine of choice in the therapy of leptospiral infections is streptomycin (DSM). Therapy using oxytetracyclines for clinical mastitis was also proven effective. Treatment is most successful in the early stage of the disease. A single dose of streptomycin administered in infected herds reduces the duration period of leptospira excretion through urine, thus preventing the spread of infection thorugh contaminated urine. The basic components of the plan to contain leptospira are the following: serological investigations, sanitary-higiene measures, the elimination of animals which excrete leptospira through urine, therapy, vaccination, quarantine.

This paper considers differential fertility and analyzes how the fertility of people caught in poverty disturbs their escape from poverty. For escape from poverty, it is necessary that the average human capital stock exceed certain thresholds before the ratio of the number of poor to rich people increases more rapidly than the human capital level of rich people. Thus, the escape depends on a race between the accumulation of human capital by the rich and the accumulation of children by the poor. A high initial ratio of the number of poor to rich people would imply persistent poverty.

The necessity to increase soil fertility by identifying their critical condition, which is associated with developing erosion processes, increasing acidity and decreasing humus, has been proven in the article. The requirement of introducing crop rotations and their legal regulation in Ukraine has been determined. The practice connected with the questions of supporting soil quality and crop rotations in different countries, members of the EU has been presented. The assessment of modern farming systems (intensive, organic, no-till, strip-till, precise, bio-enzyme, biogenic) taking into account economic, ecological, technological-energy, and social factors aimed at determining their impact on the natural soil fertility has been conducted. The expediency of improving soil quality in terms of its evaluation has been revealed. The necessity of introducing economic incentives or penalties to landowners or land users for agro-ecological condition of farmlands basing on the methods of land money value has been substantiated.

219Animal Biodiversity and Conservation 35.2 (2012)© 2012 Museu de Ciències Naturals de BarcelonaISSN: 1578–665XRosell, C. & Llimona, F., 2012. Human–wildlife interactions. Animal Biodiversity and Conservation, 35.2: 219–220. The nature of wildlife management throughout the world is changing. The increase in the world’s human population has been accompanied by a rapid expansion of agricultural and urban areas and infrastructures, especially road and railway networks. Worldwide, wildlife habitats are being transformed and fragmented by human activities, and the behavior of several species has changed as a result of human activities. Some species have adapted easily to urban or peri–urban habitats and take advantage of the new resources available. These data provide the context for why human–wildlife interactions are increasing. At the 30th International Union of Game Biologists Congress held in Barcelona in early September 2011, in addition to two plenary presentations, 52 authors from 12 different countries and three continents presented 15 papers in the Interactions of Humans and Wildlife Session, three of which are included in this volume. To some extent, all the papers reflected the inherent difficulty in solving the complex problems caused either by rapidly increasing species that begin to inhabit urban and agricultural areas in numbers not seen previously (e.g. coyo-tes, Canis latrans, inhabiting big cities; wild boar, Sus scrofa, across western Europe; wood pigeons, Columba palumbus, in France), or species whose populations are threatened by human activities (e.g., Eurasian Lynx, Lynx lynx, in the Czech Republic). Some papers addressed the contentious issue of predator control (e.g., gamebirds in Great Britain), while others presented data regarding how human activities influenced animal behavior (e.g., pink footed geese, Anser brachyrhynchus; and red deer, Cervus elaphus, in Germany). The papers presented at the congress show how human activities affect the distributions and dynamics of wildlife populations and also change the behavior of some species. Wildlife causes social and economic con-flicts by damaging agricultural and forest resources, bringing about traffic collisions, and creating problems for residents in urban areas; while many are increasingly distant from nature and may not accept the presence of wildlife others may actively encourage the presence of wild animals. The first paper in this volume, by Cahill et al. (2012), analyzes the management challenges of the increasing abundance of wild boar in the peri–urban area of Barcelona. This conflict has arisen in other large cities in Europe and elsewhere. The presence of the species causes problems for many residents, to such an extent that it is considered a pest in these areas. Wild boar habituation has not only been facilitated by population expansion, but also by the attitudes of some citizens who encourage their presence by direct feeding. This leads to wild boar behavior modification and also promotes an increase in the fertility rate of habituated females, which are significantly heavier than non–habituated females. Public attitudes regarding the species and harvesting methods (at present most specimens are removed by live capture and subsequently sacrificed) are highlighted as one of the key factors in the management of the conflict. The second paper provides an example of how the distribution of irrigated croplands influences wild boar roadkills in NW Spain (Colino–Rabanal et al., 2012). By modeling the spatial distribution of wild boar collisions with vehicles and using generalized additive models based on GIS, the authors show that the number of roadkills is higher in maize croplands than in forested areas. This factor is the main explanatory variable in the model. The paper provides an excellent example of how the synergies of diverse human elements in the landscape (maize croplands and roads in this case) affect the location and dimensions of these types of conflicts. The third and final paper, by Belotti et al. (2012), addresses the effects of tourism on Eurasian lynx movements and prey usage at Šumava National Park in the Czech Republic. The monitoring of 5 GPS–collared lynxes and analyses of data regarding habitat features suggests that human disturbance (proximity of roads and tourist trails) can modify the presence of lynxes during the day close to the site where they have hidden a prey item, such as an ungulate, that can provide them with food for several days. In such cases, adequate management of tourism development must involve a commitment to species conservation. The analyses and understanding of all these phenomena and the design of successful wildlife management strategies and techniques used to mitigate the conflicts require a good knowledge base that considers informa-tion both about wildlife and human attitudes. The papers presented stress the importance of spatial analyses of the interactions and their relationship with landscape features and the location of human activities. Species distribution and abundance are related to important habitat variables such as provision of shelter, food, comfor-table spaces, and an appropriate climate. Therefore, it is essential to analyze these data adequately to predict where conflicts are most likely to arise and to design successful mitigation strategies. The second key factor for adequate management of human–wildlife interactions is to monitor system change. An analysis of the variety of data on population dynamics, hunting, wildlife collisions, and wildlife presence in urban areas would provide a basis for adaptive management. In this respect, in the plenary session, Steve Redpath mentioned the importance of the wildlife biologist’s attitude when interpreting and drawing conclusions from recorded data and stressed the importance of conducting clear, relevant, and transparent science for participants involved in the management decision process, which often involves a high number of stakeholders. All of the papers addressing the problems associated with human wildlife interactions were characterized by a common theme. Regardless of the specific nature of the problem, the public was generally divided on how the problem should be addressed. A particularly sensitive theme was that of population control methods, especially when conflicts are located in peri–urban areas. Several presenters acknowledged that public participation was necessary if a solution was to be reached. Some suggested, as have other authors (Heydon et al., 2010), that a legislative framework may be needed to reconcile human and wildlife interests. However, each problem that was presented appeared to involve multiple stakeholders with different opinions. Solving these kinds of problems is not trivial. Social factors strongly influence perceptions of human–wildlife conflicts but the methods used to mitigate these conflicts often take into account technical aspects but not people’s attitudes. A new, more innovative and interdisciplinary approach to mitigation is needed to allow us 'to move from conflict towards coexistence' (Dickman, 2010). Other authors also mentioned the importance of planning interventions that optimize the participation of experts, policy makers, and affected communities and include the explicit, systematic, and participatory evaluation of the costs and benefits of alternative interventions (Treves et al., 2009). One technique that has been used to solve problems like these is termed Structured Decision Making (SDM). This technique was developed by the U.S. Geological Survey and the U.S. Fish and Wildlife Service. As described by Runge et al. (2009), the process is 'a formal application of common sense for situations too complex for the informal use of common sense', and provides a rational framework and techniques to aid in prescriptive decision making. Fundamentally, the process entails defining a problem, deciding upon the objectives, considering the alternative actions and the consequences for each, using the available science to develop a model (the plan), and then making the decision how to implement (Runge et al., 2009). Although complex, SDM uses a facilitator to guide stakeholders through the process to reach a mutually agreed–upon plan of action. It is clear that human–wildlife interactions are inherently complex because many stakeholders are usually involved. A rational approach that incorporates all interested parties would seem to be a productive way of solving these kinds of problems

The aim of the study is the formalization of the balance method with respect to the determination of the ecological and economic efficiency of the use of land resources. During the research, the following methods were used: statistical-economic, monographic, balance, computational and constructive. In the sphere of environmental protection, there is usually uncertainty about benefits and uncertainty about costs. Therefore, at the moment, further formalization of the assessment of the processes taking place in the system of interaction between man and land in the process of agricultural production is required. When analyzing the effectiveness of the use of agricultural land, it is important to determine not only economic, but also environmental and economic components. The ecological component of land use can be measured on the strength of the amount of prevented environmental damage applied to soil fertility, and the magnitude of the ecological effect that is created when carrying out measures to reproduce soil fertility. As the studies show, cultivating agricultural crops causes a negative balance of nutrients in the soil, and the calculation of environmental and economic efficiency indicates the need not only for joint application of organic and mineral fertilizers in optimal parameters, but also for finding alternative ways of ensuring reproduction of soil fertility.

Full textAbstract:
The idea that trade-offs between offspring quantity and quality shape reproductive behaviour has long been central to economic perspectives on fertility. It also has a parallel and richer theoretical foundation in evolutionary ecology. We review the application of the quantity–quality trade-off concept to human reproduction, emphasizing distinctions between clutch size and lifetime fertility, and the wider set of forces contributing to fertility variation in iteroparous and sexually reproducing species like our own. We then argue that in settings approximating human evolutionary history, several factors limit costly sibling competition. Consequently, while the optimization of quantity–quality trade-offs undoubtedly shaped the evolution of human physiology setting the upper limits of reproduction, we argue it plays a modest role in accounting for socio-ecological and individual variation in fertility. Only upon entering the demographic transition can fertility limitation be clearly interpreted as strategically orientated to advancing offspring quality via increased parental investment per child, with low fertility increasing descendant socio-economic success, although not reproductive success. We conclude that existing economic and evolutionary literature has often overemphasized the centrality of quantity–quality trade-offs to human fertility variation and advocate for the development of more holistic frameworks encompassing alternative life-history trade-offs and the evolved mechanisms guiding their resolution.

In this paper I build a unified model of economic growth to account for the time-series evolution of output, fertility, and population in the industrialization of an economy. Specifically, I merge the unified growth models of Galor and Weil [American Economic Review 90 (2000), 806–828] and Hansen and Prescott [American Economic Review 92 (2002), 1205–1217] to capture the importance of human capital formation, fertility decline, and the transition from agriculture to industry in transition from stagnation to growth. Moreover, I also incorporate young adult mortality into the model. Initially, the aggregate human capital and return to education are low and the mortality rate is high; therefore parents invest in quantity of children. Once sufficient human capital is accumulated and mortality rates are reduced, thanks to increasing life expectancy, with the activation of the modern human capital–intensive sector, parents start to invest in the quality of their children. The simulation of the model economy improves upon the quantitative performance of the existing literature and successfully captures the evolution of fertility, population, and GDP in the British economy between 1750 and 2000.

Agricultural lands of the Russian Federation are intensively subjected to degradation and desertification as a result of irrational economic activity, which, against the background of unfavorable climatic factors, led to the destruction of natural ecosystems, degradation of the soil cover and ultimately to the creation of the unfavorable ecological environment. About 65 % of 130 million hectares of arable land, are exposed to water and wind erosion. Only by water erosion, 10 % of arable land lost 30–60 % of fertility and almost 25 % lost 10–30 %. As a result of deflation 25million hectares of agricultural land in the European part of the Russian Federation are degraded to varying degrees. The concept of the anti-degradation arrangement proposes to use environmental-economic geoinformational monitoring. Within the framework of this approach, the development of cartographic and mathematical models in three time environments is proposed: pre-agricultural, modern degraded, and certainly improved condition. The ecological and economic analysis makes it possible to synthesize information flows and analyze the most important degradation processes. The most important tool for implementing ther adaptive-landscape anti-degradation arrangement of agricultural landscapes is precision farming, which consists of several subsystems: decision-making, monitoring, agronomic techniques, specialized equipment, etc. Computer technologies and telecommunications allow to speed up and optimize production by combining technology and people, which helps reduce costs. Precision agriculture is impossible without using modern advances in collecting, processing and storage of various, often heterogeneous, agricultural information.

Full textAbstract:
The understanding of child sacrifice requires the broader understanding of the history, context of and rationale for the concept of sacrifice in all its forms including human sacrifice. Historically, sacrifices were made to atone for sins or wrong-doing and to ask for blessings. The forgiveness was for or blessings included but were not limited to material wealth (particularly land, domestic animals and other tangible possessions), children, health, and prosperity. In spite of the variations in understanding sacrifice, common to all is the underlying guiding principle of the value for value. It means the higher the value of the blessings to be sought or wrongs to be atoned, the higher the value of the sacrificial item. Overtime, this principle has been expressed in varied forms including human sacrifice, in general, and child sacrifice, in particular. These practices are closely associated with dominant cultural value systems that people hold in relation to what is important in life and how to get it. Despite economic progress of economies characterised by sophisticated wealth computations, predictions and protection through insurance, sacrifices remain part of the social fabric for solicitation, utilisation, maintenance and protection of wealth. This chapter, therefore, broadly analyses and explains the role of economic structures and institutions on society and the influence of society on the nature of economic structures and institutions. Though there is no established scientific basis for a correlation between human sacrifice and wealth acquisition, the sacrificial items are goods of high economic value and they bring economic returns to those involved in their exchange. It is important to explain how economic wealth creates and is further re-created by sacrifices, particularly, human sacrifice. Human sacrifice is strongly dominated by child sacrifices which are believed to be without blemish and of higher atoning value. Any attempt to destroy the practice of human and child sacrifice for wealth acquisition must first destroy the dominant cultural mentalities or values systems on which they are based.

In fact, it improves some clinical aspects of various diseases, such as obesity, tumors, hypertension, Alzheimer’s disease, stroke, cardiovascular diseases, and diabetes mellitus. However, little is known about the relationship between this compound and male fertility and the few available results are often controversial. Therefore, this review evaluated the effects of RSV on human male fertility and the mechanisms through which this polyphenol could act on human spermatozoa.

Full textAbstract:
AbstractThe purpose of this study was to estimate genetic parameters for measures offertility and several health disorders in dairy cows. Data consisted of 33732 records, of which 9163 were on heifers, on 305-day milk yield, health disorders and inseminations. Measures offertility were calculated from calving and insemination dates and included calving interval, days to first service and conception to first service. Health disorders included milk fever, mastitis and lameness. Genetic and phenotypic (co)variances were estimated using restricted maximum likelihood. Heritability estimates for both health disorders and fertility traits were low, ranging from 0·003 to 0·080. All genetic correlations between 305-day milk yield and health and fertility traits, in cows and heifers together, were antagonistic implying that selection for milk yield may have caused a deterioration in health and fertility. The unfavourable correlation between milk yield and health and fertility traits, plus the economic importance of the latter, suggests that future breeding goals should be expanded to include some health disorders and fertility.
