Great Genetic Diversity

History of wheat cultivation is as long as history of civilization. Adaptation of nature, animal domestication and plant cultivation, enabled transition from nomadism to sedentism 12,000 years ago, portraying the rise of Homo sapiens of today. First civilization, Mesopotamia aroused around 4000 B.C.E, in the riverbanks of Tiger and Euphrates, where carbon-14 dating revealed that tetraploid wild emmer (Triticum turgidum subsp. dicoccoides) was grown. Due to modest cultivation requirements and high nutritional value, wheat quickly spread from its centre of origin throughout the world. Generations of farmers have chosen seeds from plants with best architecture, adapted to local conditions for sowing, striving toward constant improvement of yields. For centuries agricultural production was based on locally adapted wheat varieties of great genetic diversity. Agriculture completely changed its course in mid-XX century as a result of Green Revolution, introduction of high-yielding cereal varieties, chemical fertilizers and pesticides, irrigation and mechanization replacing traditional techniques. The flourishing of agriculture has drastically changed the course of agricultural development and global society. Improvement of agricultural techniques by integrating scientific advancements and knowledge to assimilate environmental factors has tripled wheat yields in last 50 years. Today, wheat, maize and rice, represent staple food for humanity.

The GREEN REVOLUTION has been offered as an example of both what to do and what not to do as international agriculture development. An appraisal is made of the benefits and consequences of the GREEN REVOLUTION for both wheat and rice. The history of the GREEN REVOLUTION is traced to its origins in pre-war Japan for both its concept and as the source of genetic material. The successful “production technology” approach of the wheat research program in Mexico is compared to the “appropriate technology” of the less successful maize research program. Lessons are drawn from the experience of the GREEN REVOLUTION that may prove helpful when planning or evaluating international agricultural development projects.

Impacts Of Climate Change

Drylands constitute more than 40% of global land and are particularly vulnerable to the impacts of climate change. In many of these drylands, livestock activities are a major form of land-use. In Brazil, the two major dryland biomes, Cerrado and Caatinga, play a key role in the country’s livestock activities. While important economically, these activities also contribute to the emission of high amounts of greenhouse gases. One suggested strategy for mitigating the impacts of climate change is the adoption of silvopastoral systems (SPS) which combine trees, pasture, and animals simultaneously on the same unit of land. Farmers in the drylands of Brazil have a long history of practicing SPS. The practice of silvopasture is relevant to both climate change and the economy, but not necessarily to the issues of biodiversity loss and economic inequality. The lack of interdisciplinarity in rural agricultural development projects in the past, such as those related to the “Green Revolution”, resulted in the aggravation of economic inequalities and biodiversity loss. The present work, focusing on the Brazilian Drylands, reviews these issues to justify the need for interdisciplinary projects considering multiple variables like soil quality, tree density, biodiversity richness, and farmers’ perception.

Winter Wheat Varieties

Owing to the significant differences in the adaptability of state-registered varieties, those which can adapt well to the local conditions should be given preference. There are several high-yielding varieties available in Hungary with excellent agronomic properties, good adaptability and satisfactory baking quality. This study was conducted to analyse the adaptability of 34 state-registered winter wheat varieties tested in the small plot trials of the National Institute for Agricultural Quality Control (NIAQC) at 5–9 locations between 1994 and 1997 based on their gluten quantity and farinographic index. For the comparison of the varieties the evaluation method of Eberhart and Russell (1966) was applied as modified by Bedő and Balla (1977). The qualitative stability and adaptability values of the varieties differ from the adaptability and stability values calculated from the grain yields. Some winter wheat varieties have good qualitative adaptability and stability, while others have special adaptability and poor qualitative stability, but the majority of the varieties do not belong to these groups.

What is property, and why does our species happen to have it? The Property Species explores how Homo sapiens acquires, perceives, and knows the custom of property, and why it might be relevant for understanding how property works in the twenty-first century. Arguing from some hard-to-dispute facts that neither the natural sciences nor the humanities—nor the social sciences squarely in the middle—are synthesizing a full account of property, this book offers a cross-disciplinary compromise that is sure to be controversial: All human beings and only human beings have property in things, and at its core, property rests on custom, not rights. Such an alternative to conventional thinking contends that the origins of property lie not in food, mates, territory, or land, but in the very human act of creating, with symbolic thought, something new that did not previously exist. Integrating cognitive linguistics with the philosophy of property and a fresh look at property disputes in the common law, this book makes the case that symbolic-thinking humans locate the meaning of property within a thing. The provocative implications are that property—not property rights—is an inherent fundamental principle of economics, and that legal realists and the bundle-of-sticks metaphor are wrong about the facts regarding property. Written by an economist who marvels at the natural history of humankind, the book is essential reading for experts and any reader who has wondered why people claim things as “Mine!,” and what that means for our humanity.

AbstractDespite harsh climate, agriculture on the northern margins of Russia still remains the backbone of food security. Historically, in both regions studied in this article – the Republic of Karelia and the Republic of Sakha (Yakutia) – agricultural activities as dairy farming and even cropping were well adapted to local conditions including traditional activities such as horse breeding typical for Yakutia. Using three different sources of information – official statistics, expert interviews, and field observations – allowed us to draw a conclusion that there are both similarities and differences in agricultural development and land use of these two studied regions. The differences arise from agro-climate conditions, settlement history, specialization, and spatial pattern of economy. In both regions, farming is concentrated within the areas with most suitable natural conditions. Yet, even there, agricultural land use is shrinking, especially in Karelia. Both regions are prone to being affected by seasonality, but vary in the degree of its influence. Geographical location plays special role, and weaknesses caused by remoteness to some extent become advantage as in Yakutia. Proximity effect is controversial. In Karelia, impact of neighboring Finland is insignificant compared with the nearby second Russian city – Saint Petersburg.

This paper describes the morphology of a small piece of the Chalk escarpment near Brook in east Kent, and reconstructs its history since the end of the Last Glaciation. The escarpment contains a number of steep-sided valleys, or coombes, with which are associated deposits of chalk debris, filling their bottoms and extending as fans over the Gault Clay plain beyond. Here the fans overlie radiocarbon-dated marsh deposits of zone II (10 000 to 8800 B.C.) of the Late-glacial Period. The debris fans were formed and the coombes were cut very largely during the succeeding zone III (8800 to 8300 B.C.). The fans are the products of frost-shattering, probably transported by a combination of niveo-fluvial action and the release of spring waters; intercalated seams of loess also occur. The molluscs and plants preserved in the Late-glacial deposits give a fairly detailed picture of local conditions. The later history of one of the coombes, the Devil’s Kneadingtrough, is reconstructed. The springs have effected virtually no erosion and have probably always emerged more or less in their present position. In the floor of the coombe the periglacial chalk rubbles of zone III are covered by Postglacial deposits, mainly hillwashes. They are oxidized and yield no pollen, but contain rich faunas of land Mollusca, which are presented in the form of histograms revealing changing local ecological and climatic conditions. During most of the Post-glacial Period, from the end of zone III until about the beginning of zone VIII, very little accumulation took place on the coombe floor. But below the springs there are marsh deposits which span much of this interval. They yield faunas of considerable zoogeographical interest. The approximate beginning of zone VII a (Atlantic Period) is reflected by a calcareous tufa, which overlies a weathering horizon, and represents an increase in spring flow. Two clearance phases are deduced from the molluscan record. The first may have taken place at least as early as the Beaker Period (Late Neolithic/earliest Bronze Age); the second is probably of Iron Age ‘A’ date. In Iron Age times the subsoil was mobilized and a phase of rapid hillwashing began. As a result the valley floor became buried by humic chalk muds. The prime cause of this process was probably the beginning of intensive arable farming on the slopes above the coombe; a possible subsidiary factor may have been the Sub-Atlantic worsening of climate. The muds yield pottery ranging in date from Iron Age ‘Kentish first A’ ( ca . 500 to ca . 300 B.C.) to Romano-British ware of the first or second centuries A.D. Evidence is put forward for a possible climatic oscillation from dry to wet taking place at about the time of Christ. In the later stages of cultivation, possibly in the Roman Era, the valley floor was ploughed and given its present-day form.

Participatory Variety Selection

Impacts of participatory variety selection in wheat on agro-economic changes like adoption of new wheat varieties and production technologies, income and attitude change of the wheat farmers, etc. are presented in the paper. Participatory variety selection was conducted at 12 villages of four districts in Bangladesh. Base line information from the villages was collected through participatory rural appraisal and household survey in 2002. Data on agro-economic changes were collected through household survey in 2005. Impacts were assessed from the difference of the data of two surveys. The area of the check variety Kanchan came down from 97.8% (covered in 2002) to 57% in the working villages in 2005. Varietal diversity was increased remarkably and seven varieties were found to cultivate in 2004-05. The new varieties occupied 43% of the wheat areas. Seed preservation by farmers was increased remarkably and 208 tons seeds of new varieties were preserved by them in 2004-05. When 60% seeds of their total requirements were collected from Bangladesh Agricultural Development Corporation in 2002, then, 100% seeds were used from farmers’ own source in 2004-05. There were remarkable changes in production technology adoption, sources of agricultural knowledge, attitude and income changes. Farmers’ income was increased to Tk. 11148/ha due to cultivation of new varieties and use of recommended production technologies. Participatory variety selection approach in wheat was found very useful to increase wheat production in the working villages. Widespread use of this approach may be useful throughout the county in other crops also.DOI: http://dx.doi.org/10.3329/bjar.v32i3.462Bangladesh J. Agril. Res. 32(3) : 335-347, September 2007

In the proposed article, on the basis of the materials of the Moscow Society of Agriculture identified in the fund of the Central Scientific Agricultural Library. With the involvement of the developments of researchers on the history of agrarian thought in Russia in the 19th and early 20th centuries, forms of communication between the scientific and professional communities are determined for the modernization of the agricultural sector of agriculture after the peasant reform of 1861 of the year. The publication highlights the main forms of communication: the publishing activity of the Society, the organization of exhibitions and congresses. To assess the large-scale activities of the Moscow Society of Agriculture for 110 years, a brief overview of its practical work is presented, and the role in the agrarian rationalization of agriculture in Russian historiography is revealed. Members of the Moscow Society have made a significant contribution to the study of the state of agriculture, ways of evolution and methods of increasing its productivity. On the example of materials from three All-Russian congresses on agronomic assistance to the population, the organizational aspects of resolving issues of agricultural management in the regions of Russia. The role and significance of the public initiative is especially valuable today, when the problems of innovative renewal and modernization of the agricultural sector are becoming a national task. For its successful solution, the documents of the congresses can be useful, since they make it possible to trace the genesis of the processes of agricultural development in various thematic areas and economic zones in historical terms and to avoid possible mistakes in decision-making.

Hunger and malnutrition are today associated with the capitalist system. The evidence points to a further deterioration of the food situation in the Third World in the foreseeable future, as a result of massive capital and technology transfers from the rich capitalist countries to the underdeveloped agricultures operated by transnational concerns or private investors, with the active support of development assistance agencies such as the World Bank. Contrary to the superficial predictions of the World Bank, for example, poverty is bound to increase and the purchasing power of the masses must decline. Particular attention must be paid to the supply of staple foods and the proletariat. This is threatened by a variety of factors, attributable to the operation of the capitalist system. Among them are the senseless waste of Third World resources caused by the foreign investors' insatiable thirst for the quick repatriation of super-profits and the increasing orientation of Third World agricultures toward high-value or export crops (which are usually the same), an orientation which is imposed upon them by the industrial countries' agricultural development strategies. Even self-sufficiency programs for more staple foods, such as the ill-reputed Green Revolution, predictably cannot be of long duration.
