Water development projects to manage the country's water reserves for flood control, agriculture and energy production have always been part of the Mexican federal government's politics. In southeastern Mexico these projects have been proposed to promote ‘modernization’ in a region characterized by a high level of social marginalization. A prime example of these projects is the Plan Chontalpa (referred to from here on as the Plan), a large-scale, state-led development initiative proposed by the federal government to manage the Grijalva River basin and promote industrial agricultural production and social development in Tabasco (Figure 1). Plan Chontalpa was meant to be a model for development in humid tropical regions. However, it fell short of its original goals of promoting hydroelectricity generation and agricultural production. Plan Chontalpa has been changing through the years and most recently is promoting a "green" development following the guidelines of the Puebla-Panama Plan, a regional development initiative impacting all Mexican states located south of Puebla and all the Central American countries up to Panama.

Abstract Hydropower is the second largest conventional energy resource in China. It is a renewable energy with mature technology, flexible operation, cleanliness and low carbon. A hydropower project has flood control, a water supply, navigation, irrigation and other comprehensive utilization functions. The new era in China is guided by the new energy-security strategy of ‘four revolutions and one cooperation’ and the new development concept of ‘innovation, coordination, green development, openness and sharing’. According to the dual nature of water and electricity, this paper deepens the basic understanding of hydropower from the experience of the world, the difficult problems of hydropower in China and the long-term development of hydropower enterprises. The future direction of hydropower development is explored from the following aspects: high-quality development of follow-up hydropower projects, innovative utilization of existing hydropower value, creative pursuit of hydropower-benefit growth and high-level promotion of hydropower international cooperation.

Water Uses

In this work we study long-term maximization of hydroelectric energy generation from complex multi-purpose reservoir systems, using the reservoir system of the Aliakmon River, Greece, as an application example. This system serves various purposes, like urban water supply, irrigation, hydroelectric energy production, cooling thermoelectric power plants and flood control, while preserving environmental flow. The system operator uses institutional rules for the annual scheduling of the outflows of the 2 largest reservoirs (Ilarion and Polyfyto) for additional safety and smooth distribution of energy production through the year. In this work, we focus on maximization of energy production. We have considered three different hydrological scenarios (dry, average and wet), both for the current and for anticipated future water demand. The multi-reservoir system’s operation was simulated and then optimized using a rather simple form of genetic algorithms, in order to maximize hydro energy production. All other water uses were taken into account as constraints. Our conceptual and computational approach succeeded to identify and quantify hydro energy production increase and to indicate necessary changes to the operating rule curves of the reservoirs. The methodology can be easily adapted to other large-scale multi reservoir systems.

The Second International Symposium on Magnesium was held in São Paulo, Brazil, in November 2014. An overview of the role of magnesium in food production was the theme of the opening session of that meeting. This paper considers agricultural production systems, mainly in terms of sustainability, fertiliser-use efficiency and food security, with emphasis on soils of tropical regions. Magnesium in soils and plants, as well as in relation to other nutrients and to other agricultural production factors, is especially covered. Finally, the role of magnesium is considered in terms of plant and animal health, nutrient management and the need of future research.

The need to ensure energy security, decouple energy production from fossil fuels and reduce greenhouse gas emission are driving the use of renewable energy sources. The purpose of the study is to assess the energy potential of agricultural crops biomass and to indicate its potential for electricity and heat production. The data from the Agricultural Census 2010 were used for analyses. On the basis of the detailed analysis of the changes in agricultural production in the years 2010-2015 the data has been updated. Is was assumed that the changes in communes were similar to those in voivodships. The energy potential of the crop biomass was estimated taking into account surpluses of straw, hay and perennial energy crops biomass. The study shows that energy potential of the biomass without jeopardizing food production amounts at 305,8 thousand TJ per year.

The author develops ideas about the origin of social inequality during the evolution of human societies and reflects on the possibilities of its overcoming. What makes human beings different from other primates is a high level of egalitarianism and altruism, which contributed to more successful adaptability of human collectives at early stages of the development of society. The transition to agriculture, coupled with substantially increasing population density, was marked by the emergence and institutionalisation of social inequality based on the inequality of tangible assets and symbolic wealth. Then, new institutions of warfare came into existence, and they were aimed at conquering and enslaving the neighbours engaged in productive labour. While exercising control over nature, people also established and strengthened their power over other people. Chiefdom as a new type of polity came into being. Elementary forms of power (political, economic and ideological) served as a basis for the formation of early states. The societies in those states were characterised by social inequality and cruelties, including slavery, mass violence and numerous victims. Nowadays, the old elementary forms of power that are inherent in personalistic chiefdom are still functioning along with modern institutions of public and private bureaucracy. This constitutes the key contradiction of our time, which is the juxtaposition of individual despotic power and public infrastructural one. However, society is evolving towards an ever more efficient combination of social initiatives with the sustainability and viability of large-scale organisations.

Role Of The State

In Vietnam, the construction of hydropower projects has contributed significantly in the cause of industrialization and modernization of the country. The place where hydropower projects are built is mostly inhabited by ethnic minorities - communities that rely primarily on land, a very important source of livelihood security. In the context of the lack of common productive land in resettlement areas, the orientation for agricultural production is to promote indigenous knowledge combined with increasing scientific and technical application; shifting from small-scale production practices to large-scale commodity production. However, the research results of this article show that many obstacles in the transition process are being posed such as limitations on natural resources, traditional production thinking or the suitability and effectiveness of scientific - technical application models. When agricultural production does not ensure food security, a number of implications for people’s lives are increasingly evident, such as poverty, preserving cultural identity, social relations and resource protection. Since then, it has set the role of the State in researching and building appropriate agricultural production models to exploit local strengths and ensure sustainability.

The non-black earth zone of Russia is a zone of guaranteed harvest of major agricultural crops. However, at present, the potential of the reclaimed lands of the Non-Black Earth Region remains largely unrealized. In world agricultural practice, land reclamation combined with the use of modern technical means is an important factor in the development of agriculture, a condition for a consistently high level of agricultural production. Therefore, in all countries, reclaimed lands are given a special status, and the necessary amount of reclamation fund of agricultural lands is created.

The article presents the genetic characteristic of the Chukchi reindeer breed. The object of the study was of the Chukchi reindeer. In recent years, the number of reindeer of the Chukchi breed has declined sharply. Reduced reindeer numbers could lead to biodiversity loss. The Chukchi breed of deer has good meat qualities, has high germination viability and is adapted in adverse tundra conditions of Yakutia. Herding of the Chukchi breed of deer in Yakutia are engaged only in the Nizhnekolymsky district. There are four generic communities and the largest of which is the agricultural production cooperative of nomadic tribal community «Turvaurgin», which was chosen to assess the genetic processes of breed using microsatellite markers: Rt6, BMS1788, Rt 30, Rt1, Rt9, FCB193, Rt7, BMS745, C 143, Rt24, OheQ, C217, C32, NVHRT16, T40, C276. It was found that microsatellite markers have a wide range of alleles and generally have a high informative value for identifying of genetic differences between animals and groups of animal. The number of identified alleles is one of the indicators of the genetic diversity of the population. The total number of detected alleles was 127. The Chukchi breed of deer is characterized by a high level of heterozygosity, and the random crossing system prevails over inbreeding in the population. On average, there were 7.9 alleles (Na) per locus, and the mean number of effective alleles (Ne) was 4.1. The index of fixation averaged 0.001. The polymorphism index (PIC) ranged from 0.217 to 0.946, with an average of 0.695.
