Hypertargeting Facebook Profiles Vulnerable to ISIS Recruitment with “Breaking the ISIS Brand Counter Narrative Video Clips” in Multiple Facebook Campaigns
Full text linkDespite the territorial demise of Islamic State of Iraq and Syria [ISIS], their cyberoperations continue to entice supporters. In an effort to disrupt ISIS’s appeal, the International Center for the Study of Violent Extremism has produced over 150 short video clips featuring ISIS insiders denouncing the group, published in over 100 Facebook campaigns in multiple languages and regions. This article details 16 campaigns hyper-targeted at profiles that, based on predetermined and assessed indicators, suggested increased risk of exposure to ISIS-related content. Qualitative and quantitative metrics possibly suggest positive changes in online attitudes and behavior, reducing support and incitement to terrorism
Striving for the Impossible? Policing and Territoriality in the Age of the War on Terror
Full text linkThis article asks how variations of state territorial control have influenced police missions in the recent past, and illustrate how recent police reforms were based on the structure of a ‘western’ type state with clearly identifiable formal state institutions enjoying autonomy, that strive for a form of territorial monopoly over violence. The article argues for moving beyond such assumptions by adopting scenarios based on how territory is controlled, developing four scenarios that can enable foreign-backed police missions to adapt to local circumstances. The article draws upon the typology of territorial control developed by Hansen in 2017/2019, amending this model to be adapted for policing. It argues that each of these scenarios require different strategies and compromises in order to create functioning police forces
Carrying Capacity of Traditional Farming in South East England: A Case Study
Full text linkTraditional farming in South East (SE) England is presented as a highly-evolved form of sustain- able farming. The carrying capacity of traditional farming on a 2.75 ha family smallholding in SE England is assessed from production data recorded over a period of 8 years. The key elements of the farming system were mixed farming (livestock, dairy, arable and horticultural), self-sufficiency in terms of inputs and organic principles. Ten types of food were produced with the aim to comprise all the elements of a balanced diet. The holding and farming system are described and an analysis of the food produced is presented, in terms of weight and energy content, for the years 2010 to 2017. An average carrying capacity of 0.64 people ha−1 was demonstrated on the basis of food energy content alone. Carrying capacity increased to 1.09 people ha−1 when production was re-proportioned to align with the UK Government’s currently recommended balanced diet. The latter figure is similar to carrying capacity estimates, derived from national statistics, for the UK’s total farmland in the middle part of the 20th Century but significantly lower than theoretical predictions of national carrying capacity
Socio-Ecological Implications of Soy in the Brazilian Cerrado
Full text linkThis paper summarizes the critical importance of the Cerrado savannah biome in Brazil and examines key ways in which large-scale agriculture, in particular large-scale soy farming, threatens water security and increases socio-ecological stress. It connects agribusiness expansion to the globalized meat industry by defining how complex economic relationships result in deforestation on a massive scale. It describes how this radical change in land cover has led to changes in rainfall patterns that are associated with extended drought periods and analyzes how these critical water shortages jeopardize socio-economic health beyond the immediate region. Further, it explicates how intensified transgenic soy farming and other pesticide-heavy crop production contributes to rising public health crises associated with carcinogen-contaminated water and food sources. Lastly, it identifies emerging trends that suggest how agribusiness corporations and governments may be legally ascribed moral responsibilities for maintaining socio-ecological health of the biome. The paper aims to contribute to a better understanding of the human dimensions of environmental issues and their impacts and reframe conservation social science discourse in regard to protection of land and water resources in the region
Tillage System Comparison in Organic Farming: Effects on N Mineralization, Soil Microbial Biomass, and Yield
Full text linkThe nitrogen supply can be a yield-limiting factor in organic farming, especially when reduced tillage is applied. An organic field experiment was conducted from 2007 to 2013 to analyse the potential of the nitrogen supply through the efficient use of green manure crops in different tillage systems. Three farming systems were compared: a stubble cleaner system (SC) and a plough system (PL), both in a cereal-based crop rotation, and another plough system in a crop rotation that included alfalfa grass ley (PLALF). In the fifth year of the experiment, the experimental design was extended into a split plot design, and seven green manure treatments (Lolium perenne, Phacelia tanacetifolia, Sinapis alba, a mixture of Sinapis alba and Trifolium resupinatum, Trifolium resupinatum, Vicia sativa, and bare fallow as the control) were integrated into each of the three systems. The effects of the three systems and the green manure treatments on N mineralization, the soil microbial biomass and the yield of the main crops of oats and field beans in the sixth and seventh years of the experiment were analysed. The results showed that the choice of green manure species was of minor importance in the PLALF system. This system generally success- fully supplied N to the oats with oat yields from 3.6 to 5.1 t per ha.Vicia sativa was the most promising green manure crop in the SC and PL systems, with the Nmin values and oat yields (4.0 and 4.6 t per ha) being similar to those in the PLALF system. In the subsequent year, the PLALF system again was more successful in most of the Nmin assessments than the PL and SC systems, which often had rather similar results. In addition, a main crop of field beans was able to compensate for the differences in the Nmin content, and the yields were similar in all three systems (3.1 to 3.7 t per ha). The microbial biomass in the top soil was significantly increased in the reduced tillage system compared to the plough systems. In conclusion, reduced tillage in organic farming can promote soil microorganisms and be competitive if the nitrogen supply is improved through the efficient use of green manure or an adequate leguminous main crop
Fermented Leaf Fertilizers—Principles and Preparation
Full text linkFermented leaf fertilizers (FLF) are made of anaerobically fermented plant and/or animal resources and principally used for foliar plant nutrition, as they provide a quick nutrient supply, especially of micronutrients. Their use is most common in horticultural production as a complementary measure to organic basal fertilization in the case of nutrient deficiencies. Since FLF are commonly made of farm residues, their formulation varies according to the available resources and the treated crops. The most common raw materials are cattle manure, cow milk, cane molasses, and water. Within Latin America, the production of FLF is popular with smallholders. Most of these farmers produce them on-farm using adapted plastic barrels as fermenters. Industrial production is conceivable. FLF have been successfully tested in banana, bean, broccoli, carrot, cucumber, lettuce, maize, papaya, and spinach production. This review highlights the principles of this sustainable and promising organic fertilization strategy, emphasizing the preparation of FLF
Comparative Harvest Efficiency of Soybeans between Cropping Systems Affected by First Pod Height and Plant Length
Full text linkToday, the demand for soybean for feed industry and food production in Germany is met by imports from South and North America. Soybean cultivation in Germany, although challenging, will be of interest in the future due to an increasing demand for non-genetically modified (NGM) soybeans. To meet this rising demand for NGM soybeans and to increase resource use efficiency there is a need to reduce soybean harvest losses arising from harvesting with combine harvester. The height of the first pod can be a major factor affecting harvest losses, especially when it is not possible to maintain a sufficiently low cutting height. From 2011 to 2013, six soybean varieties were cultivated using two cropping systems (conventional ‘CON’ and organic ‘ORG’) at the Osnabru ̈ck University of Applied Sciences in a randomized block design with four replications to investigate the effect of first pod height and plant length on harvest losses and the effect of the cropping system on these parameters. Before harvesting with an experimental harvester, 1.5 m2 per plot were harvested manually as a reference. First pod height, number of pods per plant and plant length were determined on 10 plants per plot. Over the three years of the study, the first pod height (10.4 cm) and plant length (81.4 cm) were on average higher under conventional conditions compared to organic cultivation (7.3 cm; 60.9 cm). On average, lower harvest losses (25.6% vs. 39.2%) and higher grain yields (20.8 dt ha−1 vs. 16.9 dt ha−1) were also observed under conventional cultivation. Varieties differed significantly in grain yield, first pod height and plant length. A high first pod height was related to a longer plant length and lower harvest losses at both sites. However, a high first pod height and a high plant length did not lead to higher grain yields on any of the plots. These results indicate that harvest efficiency can be improved by choosing varieties with long plant lengths if it is not possible to maintain a low cutting height when harvesting with a combine harvester
Sustainability Challenges in an Urban Century: Can We Change Urbanization Paths to Make Cities the Solutions for Rather than the Drivers of Global Problems?
Full text linkIs urbanization a danger or a solution to global sustainability? What institutions need to change to make urban areas more sustainable? In examining urbanization rates in countries over time, we see that they are often more correlated to carbon dioxide emissions than per capital income [1]. This tells us that urbanization patterns of the last 100 years have contributed to the increase in carbon emissions. We therefore need to develop a new kind of urbanization in order to tackle global challenges. However, reports about global changes often portray urbanization as “a problem”. Cities are polluted and increasingly crowded; urban inhabitants consume proportionately more resources and are responsible for a large portion of carbon emissions ([2], p. 927). As a urban planner, when I read those reports it seems I am looking at the books of urban planning in the last century, particularly those on urbanization in the colonies, where urbanization was presented as an unwanted process that caused a lot of harms to the “civilization” [3,4]. We must therefore change the discourse on how we describe urbanization if we want to transform it, as it will not be stopped. We must stress the many benefits that urbanization has brought to society, which are the main reasons people want to come to the cities in the first place. A question to be considered is therefore how to make urban life compatible with global challenges? i.e., how can we continue implementing/developing urbanization and the benefits that come with it without disproportionally increasing carbon emissions, the destruction of ecosystems and unsustainable consumption. There are many opportunities for win-win strategies between global sustainability challenges and development in urban areas, or synergies, such as climate co-benefits, i.e., tackling climate change and promoting development, particularly in some developing countries where cities are still being built and the path of urbanization can be changed [5,6]. Nevertheless, despite all we have learned about urbanization and the possible co-benefits opportunities since the last century, we lack understanding of the contextual and institutional conditions that make those solutions emerge
Community-Oriented Policing: Political, Institutional and Technical Reforms in Khyber Pakhtunkhwa (KP) Police
Full text linkCommunity-police relations in Pakistan are often intricate, as are their reforms. Mistrust, political intervention, meager financial resources, lack of educated/trained human resources, over-expectations and miscommunication are some of the factors contributing to weak policing and poor community-police relations. The police as a service-oriented public institution has been a demand of the public and the dream of consecutive governments. In this study, we explore the political, institutional and technical reforms taken by the government of Khyber Pakhtunkhwa (KP) and the police department to improve their police and policing. The Police Act 2017 and Community-Oriented Policing, Dispute Resolution Councils (DRCs), and Information and Communications Technology (ICT) initiatives are critically analyzed in terms of their intentions and contribution to improved police-community relations. Politicians, police, civil society organizations and community members from KP were interviewed for their perceptions of police reforms and community-police relations. The study finds strong political will to empower and depoliticize police, and to shift its focus from purely crime fighting into community service provision, including pro-active engagement of police with the community. The study also finds that most of the new initiatives of the government of KP are in the spirit of community--oriented policing, and community members see visible improvement in policing and community-police relations
Trials Evaluating Solarization and Tarping for Improved Stale Seedbed Preparation in the Northeast USA
Full text linkStale seedbeds are commonly used by organic vegetable farmers to reduce in-season weed density. The primary purpose of this study was to evaluate the efficacy of soil solarization (clear plastic) with subsequent flaming for stale seedbed preparation. A secondary objective was to compare the efficacy of solarization with tarping (black plastic). Solarization is an established weed management practice in warmer climates, but its efficacy in the humid continental Northeast USA was unknown. We hypothesized that solarization during May-June in Maine, USA would increase weed emergence, and could thereby contribute to depletion of the germinable weed seedbank and, with subsequent flaming, creation of an improved stale seedbed. We expected that firming soil with a roller prior to solarization would further increase weed emergence. Across four site-years of replicated field experiments and two on-farm trials we found that, contrary to expectations, 2 weeks of solarization reduced apparent weed emergence (density) in comparison to nonsolarized controls by 83% during treatment, and 78% after 2 weeks of observation following plastic removal and flaming. Rolling did not significantly affect weed density. Soil temperatures were elevated in solarized plots, reaching a maximum of 47◦ C at 5 cm soil depth, compared to 38◦ C in controls. Weed community analyses suggested that solarization might act as an ecological filter limiting some species. Addressing our secondary objective, two replicated field experiments compared the efficacy of solarization with tarping applied for periods of 2, 4, and 6 weeks beginning in July. Across treatment durations, solarization was more effective than tarping in one site-year, but tarping outperformed solarization in the other; this discrepancy may be explained by differences in weed species and soil temperatures between experiments. Overall, solarization and tarping are promising stale seedbed preparation methods for humid continental climates, but more work is needed to compare their relative efficacy
