When talking about animal production, there are many problems caused by the agricultural sector to the environment, which were somewhat ignored until a certain time ago, but nowadays they are part of the main issues related to the production of food animal origin. The productive chain requires that there be adequate management in each of its stages, because any negligence in any of these stages can result in health and / or environmental problems. Therefore, in assessing this context, there is a need for adequate and productive systems that fit the ecologically correct animal production issue, introducing concepts of sustainability in farms, farms, among others. The present work, through an objective review, aims to alert and signal the environmental impacts of animal production, especially to those directly or indirectly related to climate change, and, in addition, believing that the future of the Planet depends on the adoption of sustainable alternatives. Feasible solutions to reverse countless situations that have an impact on the environment

Organic farming is an alternative method for dynamic agricultural system. Products that are obtained from organic farming are referred to as ecological or organic food [1]. These include products of animal origin that come from organic farming [2]. In the case of animal production in organic farming there are particular requirements for breed, animal welfare and feeding. Additionally, the origins of animals is also of crucial importance since, basically, such animals should be purchased from organic farms. However, there can be exceptions to this requirement, for instance, if the number of animals of a particular species or of a specific breed is not sufficient [3]. The main idea behind organic production is obtaining plant or animal products maintaining good soil structure, clean water and adjusting to the natural rhythm of nature. Enhancement of the social status has led to the situation where consumers pay more attention to the quality and origins of the products they choose. Numerous scientific papers from recent years, based on consumer’s opinion, show substantial impact of welfare system on the quality of animal products. Since ‘90s there has been a systematic surge of interest in products from ecological systems and demand for these, which in turn affect the development of this agricultural sector. The aim of the work is to compare the changes in organic production over the last 26 years in Poland with reference to the situation in Europe and whole globe. The research has been done on the basis of statistics since 1990 up till now as well as on scientific studies. Nowadays, there are increasing numbers of farms and redirections of production, as well as changes in the sizes of farms producing organic food.

ABSTRACT Previous studies indicated that Campylobacter has developed several mechanisms that confer resistance to florfenicol, which is used in food animal production. This study describes the coexistence of optrA and fexA in Campylobacter jejuni and Campylobacter coli isolates from pigs and poultry. Moreover, whole-genome sequencing data showed that the two genes are located in various multidrug resistance genomic islands within different regions of the Campylobacter genomes. The emergence of optrA and fexA may support the spread of florfenicol-resistant Campylobacter strains of animal origin. IMPORTANCE Florfenicol is widely used for the treatment of respiratory infections and as a feed additive in food animal production. As a foodborne pathogen, Campylobacter is constantly exposed to florfenicol, and resistance to this antimicrobial agent has increased in recent years. Previous studies indicated that Campylobacter has developed several mechanisms that confer resistance to florfenicol. This study describes for the first time the coexistence of the florfenicol exporter FexA and the ribosomal protective protein OptrA in Campylobacter jejuni isolated from pigs. The two genes were located in various multidrug resistance genomic islands within different regions of the Campylobacter genomes. Although phenicols are not commonly used for the treatment of Campylobacter infections, the extensive use of florfenicol in food animals may play a role in the coselection of multidrug resistance genomic island (MDRGI)-carrying Campylobacter isolates which also exhibited resistance to critically important antimicrobial agents (macrolides, aminoglycosides, and tetracyclines) commonly used for the treatment of human campylobacteriosis.

Irrational and inappropriate use of antibiotics in commercial chicken and aquaculture industries can accelerate the antibiotic resistance process in humans and animals. In Bangladesh, the growing commercial chicken and aquaculture industries are playing significantly important roles in the food value chain. It is necessary to know the antibiotic usage practices and antibiotic resistance in food animal production to design rational policies, guidelines, and interventions. We conducted a narrative review to understand the level of antibiotic usage and resistance in food animal production in Bangladesh. Information about antibiotic usage in different food animal production systems, including commercial chickens and aquaculture in Bangladesh is inadequate. Only a few small-scale studies reported that the majority (up to 100%) of the broiler and layer chicken farms used antibiotics for treating and preventing diseases. However, numerous studies reported antibiotic-resistant bacteria of public health importance in commercial chicken, fish, livestock, and animal origin food. The isolates from different pathogenic bacteria were found resistant against multiple antibiotics, including quinolones, the third or fourth generation of cephalosporins, and polymyxins. Veterinary practitioners empirically treat animals with antibiotics based on presumptive diagnosis due to inadequate microbial diagnostic facilities in Bangladesh. Intensive training is helpful to raise awareness among farmers, feed dealers, and drug sellers on good farming practices, standard biosecurity practices, personal hygiene, and the prudent use of antibiotics. Urgently, the Government of Bangladesh should develop and implement necessary guidelines to mitigate irrational use of antibiotics in food animals using a multi-sectoral One Health approach.

This study was part of broader PhD research which investigated how access to, and use of, information enhances adaptation to climate change and variability in the agricultural sector in semi-arid Central Tanzania. The research was carried out in two villages using Rogers’ Diffusion of Innovations theory and model to assess the dissemination of this information and its use by farmers in their adaptation of their farming practices to climate change and variability. This predominantly qualitative study employed a post-positivist paradigm. Some elements of a quantitative approach were also deployed in the data collection and analysis. The principal data collection methods were interviews and focus group discussions. The study population comprised farmers, agricultural extension officers and the Climate Change Adaptation in Africa project manager. Qualitative data were subjected to content analysis whereas quantitative data were analysed to generate mostly descriptive statistics using SPSS.  Key findings of the study show that farmers perceive a problem in the dissemination and use of climate information for agricultural development. They found access to agricultural inputs to be expensive, unreliable and untimely. To mitigate the adverse effects of climate change and variability on farming effectively, the study recommends the repackaging of current and accurate information on climate change and variability, farmer education and training, and collaboration between researchers, meteorology experts, and extension officers and farmers. Moreover, a clear policy framework for disseminating information related to climate change and variability is required.

Use Efficiency

Coffee (Coffea spp.) represents one of the most important sources of income and goods for the agricultural sector in Central America, Colombia, and the Caribbean region. The sustainability of coffee production at the global and regional scale is under threat by climate change, with a major risk of losing near to 50% of today’s suitable area for coffee by 2050. Rain-fed coffee production dominates in the region, and under increasing climate variability and climate change impacts, these production areas are under threat due to air temperature increase and changes in rainfall patterns and volumes. Identification, evaluation, and implementation of adaptation strategies for growers to cope with climate variability and change impacts are relevant and high priority. Incremental adaptation strategies, including proper soil and water management, contribute to improved water use efficiency (WUE) and should be the first line of action to adapt the coffee crop to the changing growing conditions. This research’s objective was to evaluate at field level over five years the influence of fertilization with calcium (Ca+2) and potassium (K+) on WUE in two coffee arabica varieties: cv. Castillo and cv. Caturra. Castillo has resistance against coffee leaf rust (CLR) (Hemileia vastatrix Verkeley and Brome), while Caturra is not CLR-resistant. WUE was influenced by yield changes during the years by climate variability due to El Niño–ENSO conditions and CLR incidence. Application of Ca+2 and K+ improved the WUE under such variable conditions. The highest WUE values were obtained with an application of 100 kg CaO ha−1 year−1 and between 180 to 230 kg K2O ha−1 year−1. The results indicate that adequate nutrition with Ca+2 and K+ can improve WUE in the long-term, even underwater deficit conditions and after the substantial incidence. Hence, an optimum application of Ca+2 and K+ in rain-fed coffee plantations can be regarded as an effective strategy to adapt to climate variability and climate change.

Benefits And Costs

This experiment examines how framing power plant emissions in terms of air pollution or climate change, and in terms of health or environmental impacts, influences perceived benefits and costs of policies to reduce emissions and intentions to take political action that supports such policies. A moderated-mediation model reveals that focusing on air pollution, instead of climate change, has a positive significant indirect influence on intended political action through the serial mediators of perceived benefits and costs. Political ideology moderates the association between perceived benefits and political action. No framing effects are observed in the comparison between health and environmental impacts.

Attitude Changes

This study set up online virtual communities consisting of farmers and stakeholders involved in agriculture and nonfarmers living in rural areas interested in agricultural production. We conducted a deliberation within the communities for 14 days on identifying important climate change adaptation policies for 30 years later under climate change impacts with the relevant knowledge from experts. During the deliberation, after self-introduction took place including the realization of climate change impacts, the participants were provided with the expert knowledge on impacts of climate change, adaptation policies in agricultural sector and so on, then the following discussions covered issues such as the distribution of agricultural produce, insufficient successors, and support for farmers, such as impacts on crops during disasters concerning future scenarios. Attitude changes before and after deliberation were observed in terms of the pros and cons of climate change adaptation policies in agriculture and rural areas, but statistically significant differences were not observed. On the other hand, a statistically significant change was observed in some determinants of the pros and cons, such as the perceived effectiveness and goal intention. This structural change results from that the participants became aware of a different perspective through deliberation. Thus, the online deliberation process was effective to some extent in increasing knowledge and promoting deeper understanding among participants during inquiry and reasoning was deepened in the process as they listened to the opinions of others in a different position with a different idea as well as read and search for scientific findings and information provided by experts.
