Wall rocket (Diplotaxis erucoides) is a wild vegetable with the potential to become a crop of high antioxidant quality. The main bioactive compounds include ascorbic acid (AA), sinigrin, and a high content of total phenolic compounds (TP). It also accumulates nitrates. Since these compounds are affected by environmental conditions, adequate crop management may enhance its quality. Eleven accessions of wall rocket were evaluated under field and greenhouse conditions during two cycles (winter and spring) and compared to Eruca sativa and Diplotaxis tenuifolia crops. The three species did not differ greatly. As an exception, sinigrin was only identified in wall rocket. For the within-species analysis, the results revealed a high effect of the growing system, but this was low among accessions. The highest contents of AA and TP were obtained under field conditions. In addition, the levels of nitrates were lower in this system. A negative correlation between nitrates and antioxidants was determined. As a counterpart, cultivation in the field–winter environment significantly decreased the percentage of humidity (87%). These results are of relevance for the adaptation of wall rocket to different growing conditions and suggest that the field system enhances its quality. The low genotypic differences suggest that intra-species selections in breeding programs may consider other aspects with greater variation.

American countries and cities are among the world’s most prone to gun-related violence. In 2017, the regional homicide rate hovered at 17.2 per 100,000 people, as compared to a global average of closer to 6.1 per 100,000. Rates in Central and South America are over 24 per 100,000 population. Just four countries—Brazil, Colombia, Mexico, and Venezuela—accounted for a quarter of all global gun-related deaths. Firearms on their own are not the cause of homicide or violent crime, but their abundance dramatically increases the risk of a lethal outcome. The sheer diversity and scale of arms and ammunition moving into Latin America constitutes a serious policy challenge. This chapter focuses on the normative dimensions of arms control and emphasizes the salient policy angles, including the necessity of additional border and custom controls, oversight of local arms production, and better controls and management of military, police, and private security arsenals. To responsibly control the problem, Latin America needs better enforcement of existing laws.

Chapter 14 integrates critical views from across the domains of criminal justice, human rights, health, and development to suggest new drug policy metrics. It reveals how traditional drug policy indicators that reinforce the securitized War on Drugs discourse have justified and sustained the International Drug Control Regime since the 1960s. Rather than proving the International Drug Control Regime’s success, such traditional indicators have exposed how severe the policy has been, for example by counting the number of people incarcerated for drug-related crimes, without showing its impact. The chapter thus proposes alternative goals, targets, and indicators to overcome the current limbo situation, better track the effects of a progressive drug policy, and shift to a more holistic drug policy paradigm.
