Tree resilience to drought increases in the Tibetan Plateau
Forests in the Tibetan Plateau are thought to be vulnerable to climate extremes, yet they also tend to exhibit resilience contributing to the maintenance of ecosystem services in and beyond the plateau. So far the spatiotemporal pattern in tree resilience in the Tibetan Plateau remains largely unquantified and the influence of specific factors on the resilience is poorly understood. Here, we study ring‐width data from 849 trees at 28 sites in the Tibetan Plateau with the aim to quantify tree resilience and determine their diving forces. Three extreme drought events in years 1969, 1979, and 1995 are detected from metrological records. Regional tree resistance to the three extreme droughts shows a decreasing trend with the proportion of trees having high resistance ranging from 71.9%, 55.2%, to 39.7%. Regional tree recovery is increasing with the proportion of trees having high recovery ranging from 28.3%, 52.2%, to 64.2%. The area with high resistance is contracting and that of high recovery is expanding. The spatiotemporal resistance and recovery are associated with moisture availability and diurnal temperature range, respectively. In addition, they are both associated with forest internal factor represented by growth consistence among trees. We conclude that juniper trees in the Tibetan Plateau have increased resilience to extreme droughts in the study period. We highlight pervasive resilience in juniper trees. The results have implications for predicting tree resilience and identifying areas vulnerable to future climate extremes.

African Continental Integration and the migration question
The paper dwells on the issue of African -EU migration.It examines how the new African Continental Free Trade Agreement may help facilitate african development and free movement of persons across the continent.The paper posits that many EU countries have historical responsibility for African underdevelopment and hence must not shy away from the consequences such as migration to Europe from former African colonies.The paper also posits that this doesn't,however, doesnt excuse or detract African leadership from from the responsibility of good governance.It is a case of Common but differentiated Responsibility.One means by which this may be assured is to join hands in ensuring that the integration of objectives of African Continental Free Trade Agreement are realised.

Developing a shared understanding of the Upper Mississippi River: the foundation of an ecological resilience assessment
In support of the Upper Mississippi River Restoration (UMRR) partnership, we have been working towards an ecological resilience assessment of the system. Our first manuscript provides the foundation for our assessment, as well as an overview of historical changes and ecological understanding of the river. Working with UMRR agencies, we conceptualized the river-floodplain system as three interconnected sub-systems: lotic channels, lentic off-channel areas, and floodplains. From there, we identified controlling variables that affect major resources within each sub-system, and described those relationships as they are known. The system description provides a framework as we continue on to the assessing phase of our assessment to better understand how controlling variables influence major resources, relying on long-term spatially extensive data sets. There is growing interest in applying resilience concepts to natural resource management; however, there are few published applications of these frameworks from which to learn. We hope the UMRS resilience assessment can provide insight to others on our approach while also improving our understanding of the Upper Mississippi River System's ability to adapt to change.

A Plan for a Local Adaptive Management Fund for the Owasco Lake Watershed
Adaptive resilience work should guide all future watershed modeling efforts, rather than the current practice of developing watershed models that guide watershed best management practices.

Resilience Attributes of Social-Ecological Systems: Framing Metrics for Management
If resilience theory is to be of practical value for policy makers and resource managers, the theory must be translated into sensible decision-support tools. We present a set of resilience attributes, developed to characterize human-managed systems, that helps system stakeholders make practical use of resilience concepts in tangible applications. These resilience terms can facilitate the modeling of resilience behavior within systems, as well as support those lacking access to sophisticated models. Our goal is to empower policy makers and resource managers to put resilience theory to work in the real world.

Low Carbon Resilience: Transformative Climate Change Planning for Canada
Low carbon resilience (LCR) refers to climate change strategies that integrate and achieve co-benefits between greenhouse gas emissions reduction (mitigation) and planning designed to reduce vulnerability to climate change impacts (adaptation). To date, most strategies focus on one or the other of these two goals. This paper demonstrates the potential value of their integration, explores examples of low carbon resilience strategies, and considers options for their implementation in Canada.

The Resilience of Bergamot Farmers to Economic Shocks in the Reggio Calabria Province
Bergamot is a citrus fruit chiefly used in the fragrance industry and mainly cultivated in the Reggio Calabria district (Italy). The primary purpose of the study was to assess the contribution of bergamot production to farmers' livelihood resilience and to analyse the evolution of the bergamot sector over last years. This article is based on the quantitative analysis of originally collected data originating from the interviews to 326 farmers. The study demonstrated that bergamot production in a stable market provides an opportunity to diversify income sources and foster household resilience. Moreover if adequately supported the sector can be an engine of growth for thewhole district.
