Climate Variability and the Millennium Development Goal Hunger Target
Climate variability contributes significantly to poverty and food insecurity. Proactive approaches to managing climate variability within vulnerable rural communities and among institutions operating at community, sub-national, and national levels is a crucial step toward achieving the Millennium Development Goal of eradicating extreme poverty and hunger. Climate variability can impact a household's access to food by affecting subsistence production, income from primary production, local food prices, and sometimes the economy of an entire region. The risk of household food insecurity is determined by the success of livelihood strategies in the face of climate and other shocks. Across the economy, climate variability affects food security through its influence on investment, adoption of agricultural technology, aggregate production, market prices and economic development, and hence the ability of individuals, communities and nations to produce and purchase food. The impacts of climate variability are both ex post – losses that follow a climate shock — and ex ante — opportunity costs of conservative risk management responses to climatic uncertainty. The report summarizes the scientific basis, current methodology, and prospects for improving climate prediction at a seasonal time scale. Current forecast methods give modest to moderately-high prediction skill in "hunger hotspots" in East, West and Southern Africa, and other regions in the tropics and subtropics. Applications of climate information contribute to a comprehensive strategy to combat hunger. First is the use of seasonal climate prediction in early warning systems to guide interventions to avert food crises. Second is the use of climate information to manage risk in agricultural systems within vulnerable rural communities and among a range of institutions. This includes smallholder farmers who comprise the largest group of poor and food-insecure; intermediary institutions that interface with farmers, and can provide the information, technical guidance and production inputs required for effective climate risk management; and institutions that make climate-sensitive decisions at a broader scale that influence food security. We also discuss measures to strengthen institutional capacity and coordination to improve management of climate variability. Improved management of climate variability has appealing synergies with other interventions that target hunger, including soil fertility management, small-scale water management, markets, and extension and communication systems
Efficacy of personalized cognitive counseling in men of color who have sex with men: secondary data analysis from a controlled intervention trial.
In a previous report, we demonstrated the efficacy of a cognitively based counseling intervention compared to standard counseling at reducing episodes of unprotected anal intercourse (UAI) among men who have sex with men (MSM) seeking HIV testing. Given the limited number of efficacious prevention interventions for MSM of color (MOC) available, we analyzed the data stratified into MOC and whites. The sample included 196 white MSM and 109 MOC (23 African Americans, 36 Latinos, 22 Asians, eight Alaskan Natives/Native Americans/Hawaiian/Pacific Islander, and 20 of mixed or other unspecified race). Among MOC in the intervention group, the mean number of episodes of UAI declined from 5.1 to 1.6 at six months and was stable at 12 months (1.8). Among the MOC receiving standard counseling, the mean number of UAI episodes was 4.2 at baseline, 3.9 at six months and 2.1 at 12 months. There was a significant treatment effect overall (relative risk 0.59, 95% confidence interval 0.35-0.998). These results suggest that the intervention is effective in MOC
Low Rates of HIV Testing Among Adults With Severe Mental Illness Receiving Care in Community Mental Health Settings
OBJECTIVE: This research aimed to characterize HIV testing rates among Medicaid recipients with severe mental illness who received public specialty mental health services.
METHODS: This retrospective cohort study examined California Medicaid records from October 1, 2010, to September 30, 2011 (N=56,895). Study participants were between age 18 and 67, utilized specialty mental health care services, were prescribed antipsychotic medications, and were not dually eligible for Medicare. Adjusted Poisson regression models were used to estimate the overall effects of predictor variables on HIV testing prevalence.
RESULTS: During the study period, 6.7% of people with severe mental illness received HIV testing. Men were 32% less likely to be tested for HIV than women (p,.001). Compared with whites, Asians/Pacific Islanders were 53% less likely and blacks were 82% more likely to be tested (p,.001). Those with comorbid drug or alcohol use disorders were more likely to be tested than those without such disorders (p,.001). Utilization of non-psychiatric medical care was the strongest predictor of HIV testing (p,.001).
CONCLUSIONS: Most adults with severe mental illness receiving public specialty mental health services were not tested for HIV during a one-year period. Public health administrators must prioritize HIV testing for early identification of HIV infection and prevention of HIV transmission
Global assessment of marine plastic exposure risk for oceanic birds
Plastic pollution is distributed patchily around the world’s oceans. Likewise, marine organisms that are vulnerable to plastic ingestion or entanglement have uneven distributions. Understanding where wildlife encounters plastic is crucial for targeting research and mitigation. Oceanic seabirds, particularly petrels, frequently ingest plastic, are highly threatened, and cover vast distances during foraging and migration. However, the spatial overlap between petrels and plastics is poorly understood. Here we combine marine plastic density estimates with individual movement data for 7137 birds of 77 petrel species to estimate relative exposure risk. We identify high exposure risk areas in the Mediterranean and Black seas, and the northeast Pacific, northwest Pacific, South Atlantic and southwest Indian oceans. Plastic exposure risk varies greatly among species and populations, and between breeding and non-breeding seasons. Exposure risk is disproportionately high for Threatened species. Outside the Mediterranean and Black seas, exposure risk is highest in the high seas and Exclusive Economic Zones (EEZs) of the USA, Japan, and the UK. Birds generally had higher plastic exposure risk outside the EEZ of the country where they breed. We identify conservation and research priorities, and highlight that international collaboration is key to addressing the impacts of marine plastic on wide-ranging species
