The teleconnection of the tropical Atlantic to Indo-Pacific sea surface temperatures on inter-annual to centennial time scales: a review of recent findings

In this paper, the teleconnections from the tropical Atlantic to the Indo-Pacific region from inter-annual to centennial time scales will be reviewed. Identified teleconnections and hypotheses on mechanisms at work are reviewed and further explored in a century-long pacemaker coupled ocean-atmosphere simulation ensemble. There is a substantial impact of the tropical Atlantic on the Pacific region at inter-annual time scales. An Atlantic Niño (Niña) event leads to rising (sinking) motion in the Atlantic region, which is compensated by sinking (rising) motion in the central-western Pacific. The sinking (rising) motion in the central-western Pacific induces easterly (westerly) surface wind anomalies just to the west, which alter the thermocline. These perturbations propagate eastward as upwelling (downwelling) Kelvin-waves, where they increase the probability for a La Niña (El Niño) event. Moreover, tropical North Atlantic sea surface temperature anomalies are also able to lead La Niña/El Niño development. At multidecadal time scales, a positive (negative) Atlantic Multidecadal Oscillation leads to a cooling (warming) of the eastern Pacific and a warming (cooling) of the western Pacific and Indian Ocean regions. The physical mechanism for this impact is similar to that at inter-annual time scales. At centennial time scales, the Atlantic warming induces a substantial reduction of the eastern Pacific warming even under CO2 increase and to a strong subsurface cooling.

The millennium development goals and beyond : international assistance to the Asia-Pacific

The book examines how international aid donors and NGOs can assist countries in the Asia-Pacific region achieve the Millennium Development Goals. It examines the progress countries have made towards the MDGs and highlights the need to tailor the goals to individual country circumstances. The countries examined include Papua New Guinea, Cambodia, Solomon Islands, and Thailand.

Evidence-informed process to identify policies that will promote a healthy food environment in the Pacific Islands

Objective: To implement a systematic evidence-informed process to enable Fiji and Tonga to identify the most feasible and targeted policy interventions which would have most impact on diet-related non-communicable diseases.

Design: A multisectoral stakeholder group of policy advisers was formed in each country. They used participatory approaches to identify the problem policies and gaps contributing to an unhealthy food environment. Potential solutions to these problems were then identified, and were assessed by them for feasibility, effectiveness, cost-effectiveness and side-effects. Data were gathered on the food and policy environment to support the assessments. A shortlist of preferred policy interventions for action was then developed.

Results: Sixty to eighty policy problems were identified in each country, affecting areas such as trade, agriculture, fisheries and pricing. Up to 100 specific potential policy solutions were then developed in each country. Assessment of the policies highlighted relevant problem areas including poor feasibility, limited effectiveness or cost-effectiveness and serious side-effects. A shortlist of twenty to twenty-three preferred new policy options for action in each country was identified.

Conclusions: Policy environments in these two countries were not conducive to supporting healthy eating. Substantial areas of potential action are possible, but some represent better choices. It is important for countries to consider the impact of non-health policies on diets.

Guiding policy change to reduce diet-related disease in the Pacific

Research was undertaken in Fiji and Tonga to identify the most promising policy interventions to improve diets and non-communicable diseases. The participatory approach combined with modelling enabled evidence-informed decision-making by stakeholders. The framework developed is practical and systematic and is recommended for use in other countries in the region.

Progress on salt reduction in the Pacific Islands: from strategies to action

BACKGROUND: Most populations are consuming too much salt which is the main contributor of high blood pressure, a leading risk factor of cardiovascular disease and stroke. The South Pacific Office of the World Health Organization has been facilitating the development of salt reduction strategies in Pacific Island Countries and areas (PICs). The objective of this analysis was to review progress to date and identify regional actions needed to support PICs and ensure they achieve the global target to reduce population salt intake by 30% by 2025.
METHODS: Relevant available national food, health and non-communicable disease (NCD) plans from all 22 PICs were reviewed. NCD co-ordinators provided updates and relayed experiences through semi-structured interviews. All activities were systematically categorised according to an existing salt reduction framework for the development of salt reduction strategies.
RESULTS: Salt reduction consultations had been held in 14 countries and final strategies or action plans developed in nine of these, with drafts available in a further three. Three other countries had integrated salt reduction into NCD strategic plans. Baseline monitoring of salt intake had been undertaken in three countries, salt levels in foods in nine countries and salt knowledge, attitude and behaviour surveys in four countries. Most countries were at early stages of implementation and identified limited resources as a barrier to action. Planned salt reduction strategies included work with food industry or importers, implementing regional salt reduction targets, reducing salt levels in school and hospital meals, behaviour change campaigns, and monitoring and evaluation.
CONCLUSIONS: There had been good progress on salt reduction planning in PICs. The need for increased capacity to effectively implement agreed activities, supported by regional standards and the establishment of improved monitoring systems, were identified as important steps to ensure the potential cardiovascular health benefits of salt reduction could be fully realised in the region.

June Journeys in Brazil: from the networks to the streets

This article seeks to analyse the mass protests that ecloded in the main cities in Brazil in June 2013 - the so-called June Journeys -, event which represented an inflection moment in the country's recent political history and inaugurated a new social mobilization cycle in the country. This analysis will begin with the presupposition that the strong digital inclusion that has been going on over recent years was a main element, but not the only one, responsible for the occurrence of protests. Still, although digital inclusion has been a central tool that allowed these demonstrations to happen in the first place, it was not the only responsible for leading over 1 million people to the streets. Factors such as frustrated expectations over the continuity of the social inclusion process that had been ongoing over the last decade, the rising educational level and a political representation crisis contributed to social mobilization, and were amplified due to widening internet access - and, therefore, access to information - across the population
