The neotropical savanna is the second largest biome in South America, with significant potential for agricultural development. In Colombia, this biome is experiencing rapid land-use change leading to the conversion of seminatural landscapes into to intensive agricultural systems. Our Dataset Paper documents the emerging intensive grain production systems. Between 2011 and 2013, we established 336 observatory plots within farmer’s maize, rice, and soybean fields along a 200 Km transect from Puerto Lopez (Meta) to Viento (Vichada). From each of these plots, we submit 184 descriptors or variables capturing their location, rotation history, management, and environment. Our specific objective in collecting the data was to identify key factors explaining yield variation, with emphasis on interactions between management and environmental factors potentially informing the development of site-specific management protocols. Beyond this objective, the dataset submitted here is intended to support additional inquiries contributing to the sustainable development of agriculture in the neotropical savannas.

AbstractThe global agenda for livestock research must be led by the requirements for agricultural development, recognizing the integral and complementary rôle livestock play in sustainable agricultural systems. Demand for meat and milk will increase by more than 150 per cent over the next three decades, fuelled by the combination of income growth, population increase and urbanization. Increased demand will be primarily in developing regions, where current consumption per capita is low and livestock production systems are inefficient relative to those in developed countries. This situation encourages development to increase supply of livestock product. Research can facilitate sustainable livestock development to serve the needs of both producers and consumers.The benefits already realized from past investments in research, primarily in developed countries, help make the case for investing in livestock research. Nevertheless, the resources available for research are limited; choices must be made and expected benefits and costs should guide priorities. These benefits and costs should take into account social and environmental as well as financial values. Procedures for valuing the contribution of livestock research to sustainable development are inadequate and, in themselves, are a priority in the global agenda.Priorities for research differ but are generally linked across the levels of agricultural systems: household, community, landscape, national, regional and international. Specific priorities in the global agenda vary with livestock species (ruminant, non-ruminant), production systems (grazing, mixed, industrial), agro-ecological and socio-economic factors (especially, those differing for developed and developing regions) and whether research will be supported by public or private sector funding. The priorities for developing countries emphasize increasing productivity and efficiency; whereas for developed countries, more emphasis is given to food safety, zoonotic diseases and environmental issues. Non-traditional, but increasingly important priorities derive from the need for information and technologies to improve soil and water management to ensure long-term sustainability of livestock production systems and for socio-economic analysis to provide policy options for decision makers.The global agenda for livestock research is broad, embracing the full spectrum from basic to adaptive research. The traditional animal sciences will continue to be important but there is increasing need to draw from crop and environment research, from human health and genetics research, inter alia. Results from research in developed regions can be adapted to the needs of livestock systems in developing regions. In return, research on genetic resistance developed through natural selection in livestock populations in developing regions, may provide environmentally friendly means to control livestock disease and parasites in developed regions. The challenges posed by the global agenda are considerable. To meet these challenges, partnerships are required, linking skills, capacities and access to problems. The successes of these research partnerships will meet the requirements for sustainable agricultural development and ensure support for livestock research in the future.

Subject. A considerable amount of agricultural innovation pursues to create sustainable production systems, including land and water resource management, the development of agri-environmental approaches to using ecological and biological processes to reduce the consumption of non-renewable resources. Despite the apparent importance of the issue, the national agriculture still scarcely uses innovation. Objectives. We investigate the enhancement of the sustainable development in agriculture through innovation. Methods. The study relies upon proceedings of foreign and Russian scholars on theoretical and practical aspects of the sustainable development in agriculture, official statistical data and documents of governmental and special-purpose programs for agricultural development in the Russian Federation. The study is methodologically based on the systems approach. Results. Agriculture is found to be in transit to the sixth wave of innovation, with its core comprising NBICS-technologies and synthesizing nano-, bio- and computer technologies, genetic engineering and cognitive ties. Biological innovation and land cultivation innovation are the most popular and sought-for, since they ensure the prolonged economic effect. We determine factors impeding the innovative development in agriculture. Computer systems and public-private partnership are supposed to be the main tools for activating innovation. Conclusions and Relevance. I conclude that, despite some disputable aspects of some innovative solutions in agriculture, sustainable development in agriculture is undeniably impossible without such innovative solutions. Rising controversies can only be resolved through further and more profound research. The State should assist in the emergence of the effective innovative environment, which would allow all agricultural market actors to actively implement innovation.

The perception of a basic education of the importance of agroecological agricultural systems for human and environmental health is fundamental for changes in consumption habits, the conservation of local biodiversity and long-term social transformation. We analyzed, by utilizing a questionnaire consisting of open and closed questions, the perceptions about agroecological and conventional agricultural production systems in 360 final students of basic education residing in nine Functional Planning Regions of southern Brazil. We used classification categories for answers within thematic axes, expressed in percentages and analyzed by means of Chi-square and Kruskal-Wallis tests. In general, students recognize agroecological systems as healthier for their families and for soil and water conservation, largely because they do not use agrochemicals. However, they demonstrated difficulties when arguing their importance for the conservation of biodiversity, ecosystems and for ensuring the food security of populations. Television was the main source of information related to agroecology, mainly for students residing in rural areas, thus pointing out shortcomings in basic education regarding the approach of the theme in schools. Our results show the need to build a complex network of knowledge and discussions on agroecological agricultural systems in basic education, involving changes in student perceptions, behaviors and sustainable choices.

In December, 1987, the states in the Chesapeake Bay region, along with the federal government, signed an agreement which called for a 40% reduction in nitrogen and phosphorus loadings to the Bay by the year 2000. To accomplish this goal, major reductions in nutrient loadings associated with agricultural management practices were deemed necessary. The objective of this study was to determine if reducing fertilizer inputs to the NT system would result in a reduction in nitrogen contamination of groundwater. In this study, groundwater, soil, and percolate samples were collected from two cropping systems. The first system was a conventional no-till (NT) grain production system with a two-year rotation of corn/winter wheat/double crop soybean. The second system, denoted low-input sustainable agriculture (LISA), produced the same crops using a winter legume and relay-cropped soybeans into standing wheat to reduce nitrogen and herbicide inputs. Nitrate-nitrogen concentrations in groundwater were significantly lower under the LISA system. Over 80% of the NT groundwater samples had NO3-N concentrations greater than 10 mgl-1, compared to only 4% for the LISA cropping system. Significantly lower soil mineral N to a depth of 180 cm was also observed. The NT soil had nearly twice as much mineral N present in the 90-180 cm portion than the LISA cropping system.

Agricultural development is facing two problems: insufficient grain production and low profit of farmers. There is a contradiction between the government’s goal of increasing production and the farmer’s goal of increasing profit. Exploring the appropriate management scale of farmland under different objectives is of great significance to alleviate the conflict of interests between the government and farmers. In this study the Cobb-Douglas production function model was used to measure the appropriate management scale of farmland under different objectives in Shaanxi Province and analyze the regional differences. Under the two objectives, the appropriate management scale of the Loess Plateau was the largest in the three regions, followed by Qinba Mountains and Guanzhong Plain. Farmland area and quality were the main influencing factors for the appropriate management scale of farmland under the goal of maximizing the farmland yield, while the nonagricultural employment rate and farmland transfer rate were the main influencing factors under the goal of maximizing farmers’ profits. It is easy for Shaanxi Province to increase farmers’ profits, but more land needed to be transferred to increase farmland yield. These results suggest that in order to balance the goal of increasing yield and profit, the transfer of rural surplus labor should be promoted, and the nonagricultural employment rate should be improved. In Loess Plateau, restoring the ecological environment and enhancing the farmland quality. In Guanzhong Plain, avoiding urban land encroachment on farmland. In Qinba Mountains, developing farming techniques and moderately increasing the intensity of farmland exploit.

About two billion rural individuals depend on agricultural systems associated with a high amount of risk and low levels of yield in the drylands of Asia, Africa, and Latin America. Human activities, climate change and natural extreme events are the most important drivers of desertification. This phenomenon has occurred in many regions of Iran, particularly in the villages in the periphery of the central desert of Iran, and has made living in the oases so difficult that the number of abandoned villages is increasing every year. Land abandonment and land-use change increase the risk of desertification. This study aims to respond to the research questions: (i) does the planning of green infrastructures on the desert margin affect the distribution and balance of the population? (ii) how should the green belt be designed to have the greatest impact on counteracting desertification?, and (iii) does the design of productive landscape provide the solution? Through a wide-ranging and comprehensive approach, this study develops different scenarios for designing a new form of green belt in order to sustainably manage the issues of environmental protection, agricultural tradition preservation and desertification counteraction. This study proposes a new-traditional greenbelt including small low-cost and low-tech projects adapted to rural scale.

Multimodal freight transport in cities is a complex, valid, and vitally important problem. It is more seldom underlined in scientific studies and included in cities’ strategies that devote more attention to passenger transport than freight transport. The increased utilization of multimodal transport matches current transport policy and at the same time, it is one of the most important challenges put before cities striving to achieve sustainable development. In this case, the paper embarks upon the problem of relations between multimodal transport development and the sustainable development of the cities. The objective of the paper is an analysis of the impact of the selected city of the Upper Silesian metropolis on the development of multimodal freight transport and an assessment of the impact of the development of multimodal transport on the sustainable development of the cities of the Upper Silesian metropolis. The authors developed three research questions in order to implement the adopted objective. The process of looking for the answer included four stages. Within the first and second stages, the literature studies and experts’ research allowed for identifying key factors of the multimodal transport development that a city may have an impact on. In the third stage, the research was two-fold and was based on a questionnaire and scenario analysis. Due to the individual character of each of the cities, scenarios were developed for Katowice, being the main economic center of Upper Silesian and Zagłębie Metropolis. As a result of the research, factors have been identified that must be included in a strategy of a city that strives for sustainable development. The last stage of the research focused on the initial concept of the multimodal transport development impact assessment on sustainable development of the cities. Conclusions developed at individual stages allowed for answering the research questions.

AbstractConventional agriculture often aims to achieve high returns without allowing for sustainable natural resource management. To prevent environmental degradation, agricultural systems must be assessed and environmental standards need to be developed. This study used a multi-factor approach to assess the potential environmental impact risk of six diverse systems: five production systems and a successional system or abandoned agronomic field. Assessment factors were soil quality status, amount of pesticide and fertilizer applied and tillage intensity. The assessment identified the best management practices (BMP)–conventional tillage system as a high-risk system mostly because of extensive tillage. The certified organic system was also extensively tilled and was characterized by P build-up in the soil, but performed well based on other assessment factors. Conversely, the BMP–no tillage and the crop–animal integrated system were characterized as low risk mainly because of reduced tillage. The paper discusses assessment strengths and weaknesses, ways to improve indicators used, and the need for additional indicators. We concluded that with further development the technique will become a resourceful tool to promote agricultural sustainability and environmental stewardship and assist policy-making processes.

Global warming has become international concern, culminating with the ratification of the Kyoto Protocol which includes definitions and objectives of the sustainable development mechanisms and features that make it easier for the industrialized countries to jointly compensate for their polluting greenhouse gas emissions. Porciúncula is a city known for its agricultural development and the lack of characterization of ecosystems associated with the Atlantic Forest biome. Facing this chaotic scenario is Nova Canaã farm located in the Ribeirão da Perdição Environmental Preservation Area its forest ecosystem provides a series of environmental services such as carbon storage and CO2 sequestration. The team of researchers from OM Consultoria Ambiental performed the quantification of the biomass (Bwood) of the bole which resulted in estimates of 398.4753 t.ha-1 corresponding to 199.2377 tC.ha-1. The estimates obtained for the forest ecosystem of the farm can be used as a reference for the establishment of forest restoration projects under the under the sustainable development mechanism established the Kyoto Protocol.
