Urban Community Garden Agrodiversity and Cultural Identity in Philadelphia,Pennsylvania, U.S.

Considerable research has examined the social, cultural, economic, and community benefits of urban gardening. Few studies, however, have empirically assessed factors that influence urban community garden agrodiversity or its relationship to these dimensions of gardening. We conducted an interdisciplinary study of agrodiversity and cultural identity, based certain markers of identity, including how people see themselves with respect to race, ethnicity, or place of origin, in community gardens in Philadelphia, Pennsylvania. We conducted fifty‐six semistructured interviews with gardeners with different cultural identities in eight community gardens on their motivations for urban community gardening during 2014. We conducted plant inventories of the corresponding garden plots and found 104 cultivated edible and ornamental species and 28 varieties representing 34 families. We find that although gardens with culturally diverse gardeners did not have higher species richness, the cultural identity of the gardeners influenced species selection and reason for gardening. Further, the structure, design and species composition of garden plots reflected the identities of garden members. These finding have implications for the recent institutionalization of urban agriculture into city land policies in Philadelphia and other cities in North America.     

Do perceptions of the Red‐tailed Hawk indicate a human‐wildlife conflict on the island of La Gonave,Haiti?

The Caribbean subspecies of the Red‐tailed Hawk (Buteo jamaicensis solitudinus or B.j. jamaicensis) is the largest native carnivore on the island of La Gonave, Haiti, and the island's apex predator. On other Caribbean islands, raptors have been persecuted by local people typically because of their depredation of livestock. In addition to possible persecution from humans, Red‐tailed Hawks on La Gonave face challenges from island‐wide timber overharvest and rapid land‐cover changes. To better understand the human‐apex predator relationship on La Gonave, we surveyed islanders about their perceptions of, and interactions with, the Red‐tailed Hawk. According to 121 respondents from 10 villages, La Gonavans do not hunt, kill, or consume Red‐tailed Hawks. Our study revealed a notable absence of negative perceptions of the hawk by respondents despite intense hawk depredation of domestic chickens. While the chicken depredation may lead outside observers to consider the human‐hawk relationship on La Gonave as representative of a human‐wildlife conflict, our interview data do not support that conception. Our findings reflect an important conversation in related contemporary scientific literature about what constitutes human‐wildlife conflicts across various cultures. Despite tolerance by residents, Red‐tailed Hawks on La Gonave remain threatened by habitat degradation.     

Facies system of the Eastern Barents Sea since the last glaciation to present

Twenty-two sediment cores raised from the central and eastern parts of the Barents Sea have been studied to reconstruct the evolution of the facies system since the Late Weichselian glaciation. Multiproxy records reveal four lithostratigraphic units, which reflect major development stages of paleoenvironments. Age control is provided by 23 AMS ¹⁴C dates for Holocene sections of four cores. Continental moraine deposits of the last glaciation are overlain by proximal glaciomarine facies of the initial deglaciation phase. During this phase, the Barents Sea ice sheet detached from the ground resulting in seawater penetration into troughs, iceberg calving, deposition of IRD and fine-grained glacier meltwater load in newly formed marine basins. The main deglaciation phase is characterized by pulsed sedimentation from various gravity flows resulting in accumulation of distal glaciomarine facies comprising laminated clay and sand sequences with minor IRD. Redistribution of fine-grained suspended matter by bottom currents and brine-induced nepheloid flows combined with biogenic processes and minor ice rafting caused facies diversity of the Holocene marine sediments. The Holocene facies of shelf depressions reflect rather high, but variable productivity responding to climate changes and variations of Atlantic water inflow into the Barents Sea.     

Fisheries compliance in South Africa: A decade of challenges and reform 1994–2004

In South Africa, fishery managers have struggled with a number of challenges in terms of compliance amidst a process of legal and policy reform since the democratic elections of 1994. The past 10 years, and more specifically the past five, have seen a significant change in compliance effort, with a particular focus on increasing law enforcement activities and capacity. This paper highlights two case studies that have been instrumental in restructuring fisheries compliance in South Africa. Although law enforcement has been significantly strengthened, greater political will and government commitment is required to implement alternative strategies that will have a long-term impact on levels of compliance.
