Abstract:
ABSTRACT Sensitivity mapping recently completed for Puerto Rico, the U.S. Virgin Islands, and the British Virgin Islands combines information on natural resources for both coastal and inland areas, covering both U.S. Coast Guard and U.S. Environmental Protection Agency jurisdictions. This planning and response tool includes detailed Environmental Sensitivity Index (ESI) maps for the coastal zones of Puerto Rico, the U.S. Virgin Islands, and the British Virgin Islands. Reach Sensitivity Index (RSI) maps for small rivers and streams in Puerto Rico have been developed, and sensitive biological and human-use resources have been mapped throughout inland and upland habitats for the entire project area.

Abstract:
Three years after Hurricane Maria, rural municipalities of Puerto Rico find themselves as vulnerable as before the category 4 storm dwindled the Island’s resources. The town of Aguas Buenas is among the rural municipalities struggling to prepare for the next natural disaster. This pilot study provides a plan for activating the community with the purpose of forming the first community emergency management team (CEMT) in coordination with local officials. Through in-depth interviews with the people living in Aguas Buenas, the study presents a situation analysis followed by recommendations on how to train the community leaders and turn the crisis into an opportunity for collaborative engagement.

Abstract:
ABSTRACT The U.S. Roosevelt Roads Naval Station (RRNS) lies near the municipality of Ceiba on the southeastern coast of Puerto Rico. On October 20, 1999, RRNS personnel reported a spill of JP5 fuel oil, which was officially determined to be 112,000 gallons. The oil spilled from a day-tank into a 50-acre basin mangrove forest and then into the northern Ensenada Harbor. Initial spill response activities by the U.S. Navy Construction Battalion (Seabees), including construction and placement of both underflow and culvert dams, were carried out in the face of an approaching hurncane. This damming effort resulted in both positive and negative consequences for the survival of the mangrove forest. In addition to the cleanup activities, the federal trustees—including the U.S. Navy (USN), the National Oceanic and Atmospheric Administration (NOAA), and the U.S. Fish and Wildlife Service (USFWS)—initiated a natural resource damage assessment (NRDA). The primary objectives of the damage assessment were to identify potential natural resources at risk, determine the horizontal extent of contamination within the basin mangrove, and document exposure and/or injuries to natural resources resulting from the spill. This paper examines the overall effectiveness of the spill response operations, discusses the difficulties in conducting cleanup activities in a basin mangrove environment, and describes coordination efforts between cleanup activities and natural resource response activities.

Abstract:
The term resilience has saliency in the scholarship and policy on post-disaster management and disaster-risk reduction. In this paper, we assess the use of resilience as a concept for post-disaster reconstruction in Puerto Rico and offer a critique of the standard definition. This critique focuses on the primacy of Puerto Rico’s colonial relations with the United States meshed with decades of political mismanagement of the island’s economic and natural resources by local authorities and political parties. For resilience to be a useful conceptual device, we argue for decolonizing resilience and show the relevance of such an argument through a case study of the island’s coffee-growing region. Decolonizing resilience exposes power inequities and the individuating nature of post-disaster reconstruction to illustrate how collective action and direct participation of local actors and communities carves out autonomous spaces of engagement. Decolonizing resilience necessitates a contextualized analysis of resilience, taking into account “the politics of resilience” embedded in the island’s colonial history and the policy bottlenecks it creates.

Abstract:
The twin epidemics of HIV and incarceration impact Puerto Rico, which has limited resources to address the social and structural determinants of health in incarcerated populations. A Special Programs of National Significance grant supported a Puerto Rican community-based organization to implement the evidence-informed Transitional Care Coordination intervention among incarcerated persons living with HIV, targeting changes at the individual, organization, and systems levels. After implementation (November 2015–July 2018; n = 69), 93.1% of eligible clients were linked to community-based HIV care, 86.3% remained in care for 6 months, and 78.6% remained for 12 months. A greater proportion reported consistent HIV care, ART adherence, food security, and transportation to access care. Integrating HIV case management with housing and employment services, and developing buy-in and collaboration from partners across systems of care, including after a natural disaster, led to positive client outcomes. This intervention shows promise for adaptation to other HIV care and service delivery systems.

Abstract:
The connection between the environment and human rights is not a surprising one. The enjoyment of human rights depends on a person’s ability to live free from interference and to have his or her rights protected. The interdependence of human rights and the protection of the environment is manifested in the full and effective enjoyment of the right to a healthy environment. This article argues that in order to protect vulnerable persons and communities facing environmental harm, a human rights framework—specifically the right to a healthy environment—must be applied. A human rights approach complements environmental justice work, recognizing that individuals and communities affected by environmental harm are rights-holders entitled to protection. Such communities are left out of important decisions about their environment and the effect of environmental harm in their lives. Individuals most vulnerable to environmental harm are often members of poor, rural, and disenfranchised communities. The destruction of the environment disproportionately affects these communities, preventing them from accessing basic natural resources, clean water and sanitation, adequate housing, food security, and access to health and medical assistance. Additionally, intersecting forms of discrimination exacerbate exclusion and marginalization. A human rights approach to environmental justice emphasizes the need to protect affected communities and holds the State responsible for recognizing their vulnerability and providing heightened protection. This article seeks to show that while the human right to a healthy environment has not been widely recognized, a robust juridical framework enables environmental justice advocates and affected communities to vindicate the rights of vulnerable communities. The case study of coal-ash contamination in Puerto Rico and the harms suffered by affected communities there anchors the argument for why advocates should use a human rights framework to protect the rights of the most vulnerable. The case of Puerto Rico is illustrative of so many poor, disenfranchised, and vulnerable communities around the world, affected by environmental harm and in need of a human rights-based framework.

Abstract:
AbstractRecent droughts in Puerto Rico and throughout the Caribbean have emphasized the region's agricultural vulnerability to this hazard and the increasing need for adaptation mechanisms to support sustainable production. In this study, we assessed the geographic extent of agricultural conservation practices incentivized by US Department of Agriculture Natural Resources Conservation Service (NRCS) and evaluated their large-scale contribution to drought adaptability. We identified concentrations of drought-related practices (e.g. cover crops, ponds) applied between 2000 and 2016. Using information from spatial databases and interviews with experts, we assessed the spatial correlation between these practices and areas exposed to drought as identified by the US Drought Monitor. Between 2000 and 2016, Puerto Rico experienced seven drought episodes concentrated around the south, east and southeastern regions. The most profound drought occurred between 2014 and 2016 when the island experienced 80 consecutive weeks of moderate drought, 48 of severe drought and 33 of extreme drought conditions. A total of 44 drought-related conservation practices were applied at 6984 locations throughout 860 km2 of farmlands between 2000 and 2016 through the NRCS-Environmental Quality Incentives Program (EQIP). Practices related to water availability were statistically clustered along the coasts, whereas soil and plant health practices were clustered in the mountainous region. While these concentrations strongly correlated with areas exposed to moderate drought conditions, >80% did not coincide with areas that experienced severe or extreme drought conditions, suggesting that areas highly exposed to drought conditions generally lacked drought preparedness assisted by EQIP. Climate projections indicate an increase in the frequency and intensity of drought events, particularly in the eastern region of Puerto Rico. Our analysis highlighted the need to implement more conservation practices in these areas subject to drought intensification and exposure. Government programs intended to address vulnerabilities and enhance capacity and resilience may not be reaching areas of highest exposure. Recommendations include raising producer awareness of past and future exposure and making programs more accessible to a broader audience.

Abstract:
Disaster preparedness and disaster mitigation are the goals of nations throughout the world during the 1990's. The United States will lead this cooperative effort and marshall its national resources to reduce the disaster potential of earthquakes, floods, windstorms, landslides, volcanic eruptions, tsunamis, and wildfires. These natural hazards cause annual losses of approximately $10 billion in the United States and many times that throughout the world. The type and severity of the hazard varies from State-to-State in the United States. All States are at risk from flooding from sources such as precipitation, snowmelt, thunderstorms, and, along the coast, the storm surges generated in hurricanes. No State is free from the potential impacts of ground shaking induced by earthquakes, although the frequency of damaging earthquakes is much greater in Alaska and California than in the remainder of the Nation. Landslides also occur in all the States and Territories. The Western States are potentially vulnerable from wildfires and volcanic eruptions. Damaging tsunamis in the past have struck Hawaii, Alaska, Washington, Oregon, California, Puerto Rico, and the Virgin Islands. The goal of the Decade is to keep such occurrences in the future from being disasters.

Abstract:
ABSTRACT The January 7, 1994, barge Morris J. Berman grounding and oil spill off Punta Escambrín, near San Juan, Puerto Rico, resulted in injury to natural resources along the shoreline and impaired their use for an extended time. Three major injury categories were pursued by the Trustees and the restoration projects for these injuries are presented in this paper. Including interest, approximately $10M in settlement funds are being used to fund 6 restoration projects. About $6 million of the settlement funds is being used for three projects to restore eolianite reef habitat, a type of fossilized sand dune, and other reef resources injured by the barge grounding and subsequent spill. One project, called the Condado Coral Trail project, will install artificial reef modules in the Condado Lagoon, approximately 1 mile southeast of the barge grounding site. Also in the Condado Lagoon, a 32-acre dredge hole will be brought back to historic elevations through beneficial use of dredged marine sediments. The third reef project entails acquisition of shoreline and coastal property which is intended to provide reef resource services comparable to those lost as a result of the oil spill and grounding. This parcel provides habitat for over 40 rare species of plants and animals including a major nesting beach for the endangered Leatherback Sea Turtle. The acquisition project also serves as the sole compensatory restoration project for lost recreational beach use. The parcel is being designated as a Puerto Rico Natural Reserve thereby allowing the public to use the land, including its unspoiled beaches, for recreational purposes. Finally, three restoration projects are being implemented to compensate for the lost historic visitor use services at the San Juan National Historic Site. More than 123,000 visitors to the El Morro and San Cristobal forts were affected by the spill for approximately six weeks. The first of the three projects includes Improving and Extending the Coastal Promenade, a walkway at the base of El Morro. The second is restoration of El Morro Water Battery and the third is cleaning and stabilizing certain exterior walls of the El Morro Fort.

Abstract:
After sixty-two years of U.S. military testing, the small Puerto Rican island of Vieques and its residents continue to fight against ongoing environmental and social effects of U.S. hegemony. Starting with the arrival of the Spanish, then with U.S. occupation and use of Vieques as a military stopover, Viequense residents are used to U.S. governmental presence on their land. Despite the military’s removal from Vieques in 2003, many local residents have a fundamental lack of trust for the U.S. government. Because of this lack of trust and transparency with U.S. governmental actions in the post- World War II period, residents of Vieques do not see any difference between the USFWS, the EPA, CH2M Hill, and the U.S. Navy. However, many acknowledge that the U.S. government’s involvement may be good for the island, so there is some ambivalence about the U.S. government’s continued presence on the island, its role in developing Vieques, and bettering its current economic situation. While the majority of local activists claim that naval activities negatively affected island life through contamination of land and surrounding waters, also resulting in a range of human health problems, others argue that the U.S. Navy should not be demonized, and the island’s role in conservation should be paramount. These differing views reflect two opposing frameworks: one fighting against a colonizer and U.S. hegemony, and the other promoting a primarily conservation-based framework meant to protect non-human residents.

Abstract:

Characterization of bacteria community and evaluation of anthropogenic and natural disturbances in surface waters quality of Sabana River in the Luquillo Experimental Forest in Puerto Rico. This doctoral dissertation research focused on the bacterial characterization, and evaluation of anthropogenic, and natural disturbances in the surface waters quality of the Sabana River in the Luquillo Experimental Forest in Puerto Rico. Monthly samples were taken at seven stations along the river during one year, and physicochemical factors such as temperature, pH, conductivity, DO and salinity were measured to explore their effect in the bacterial community. The effect of recreation was evaluated at El Puente, and at La Paila in the Sabana River, and at Puente Roto in the Mameyes River, from August 4 to September 8, 2012. Samples were collected up-river (before), on-site, and down-river (after) primary contact recreation activity. The number of bathers, and the temperature of the water were recorded. Also, four monthly sampling events were conducted under low flow conditions between May 2015 and August 2015, at two sites in the Sabana River impacted by non-point sources. Terminal restriction fragment length polymorphism (T-RFLP), pyrosequencing, and Colilert and Enterolert Test-System, were used for the bacterial community characterization. It was found that number of phylotypes of the bacterial community increases from upriver to downriver as anthropogenic disturbances proliferate along the river, and that bacteria are adapted or acclimated to in situ temperature, dissolved oxygen, conductivity, salinity and pH, therefore, show little variation in time and space. Pyrosequncing revealed that a total of 12 bacteria classes, 27 orders, 33 families, 82 genera and 186 species were found in the Sabana River. There is an increase in families and species through the three stations, with the largest amounts observed downriver at station # 7. Vogesella spp. was the most abundant specie at the three stations, with 59% at station # 1, 67% at station # 4, and 53% at station # 7. A significant positive and strong correlation was found between the amount of E. coli and the number of bathers at MPRS (R = 0.919; p-value = 0.027), which means that a high number of bathers coincides with a high concentration of E.coli.

Also, there is a significant positive and strong correlation between the concentration of Enterococci and the number of bathers at Pai.S (R is 0.908; p-value = 0.033). There were not significant differences between the bacterial community up-river, on site and down river of the two non-point sources.

Abstract:
The philosophy of research in the Long-Term Ecological Research (LTER) program expanded what I learned in graduate school from H. T. Odum by providing an approach for a holistic understanding of ecological processes in the tropics. Participation in the LTER program enabled collaborations with many talented people from many parts of the world and enabled the mentoring and education of a new cadre of tropical natural and social sciences students. By expanding the opportunities for research and analysis at larger scales, the LTER program allowed me to address tropical ecosystem responses to such phenomena as hurricanes, floods, landslides, and past land uses and to do so at the appropriate scales of time and space. Paradigms of tropical forest resilience and adaptability in the Anthropocene emerged from research at the Luquillo (LUQ) LTER site. I first became aware of the LTER program in 1978 as I walked by the White House in Washington, DC, with Sandra Brown, then an intern on the President’s Council on Environmental Quality (CEQ), and Wayne Swank, a US Forest Service employee on detail with the National Science Foundation (NSF). I was a staff member at CEQ, and W. Swank explained to us a new long-term ecological research program that he was helping develop at the NSF. Although the first cadre of sites appeared to have been selected, I was immediately captured by the concept and expressed my interest in developing a proposal for a tropical site in Puerto Rico. Little did I know at the time that my whole scientific career was about to change, in part because of the LTER program, but also because I was to become a US Forest Service scientist. The first 30 years of my US Forest Service career would be heavily influenced by the LTER program and the people I worked with while developing a new way of thinking about tropical forest ecosystems. I am an ecologist trained at the Universities of Puerto Rico and North Carolina at Chapel Hill. My experience before becoming part of the LTER program involved (1) teaching at the University of Florida at Gainesville and (2) government work at the Commonwealth (Puerto Rico Department of Natural Resources) and federal (President’s Council on Environmental Quality) levels.
