Wild foods are an integral component of the household food basket, yet their quantified contribution to food security relative to other sources in the context of HIV/AIDS, climate change and variability remains underexplored. This study was carried out in Willowvale and Lesseyton which are rural communities in the Eastern Cape province of South Africa.

Climate change poses a very real threat to millions of Africans, especially those who rely on the natural world for their livelihoods. The increasing variability of climate and rainfall patterns are said to have dire consequences on agricultural production which is the main livelihood activity of rural dwellers across the continent.

Rural communities in sub-Saharan Africa are faced with multiple interconnected challenges such as population growth, environmental change, economic recession and climatic changes, amongst others. Such challenges can play a key role in determining vulnerability and food security, particularly for natural resource productdependent societies that have limited livelihood sources. Studies that consider understanding how society and ecosystems simultaneously interact and respond to new and exacerbated drivers are increasingly needed.

This report reviews the options for support to grassland restoration in the context of demand growth for livestock products and climate change mitigation. Key messages are: Grasslands provide crucial economic, social and environmental outputs Gasslands cover a total of 52.5 million km2 , or about 40% of the world’s ice-free terrestrial surface area. Extensive grasslands contribute about 7% of global beef production, 12% of sheep and goat meat production and 5% of global milk supply.

Participatory digital mapping using satellite imagery and digital earth and other open source Geographic Information Systems (GIS) is a practical tool bridging the knowledge and communication gap between pastoral communities and county government planners. It is offering an effective option for participatory planning and decision-making in support of climate change adaptation in the drylands of Kenya.

Basic survival is very difficult for the 1.2 million people who live in Karamoja, a remote region in northeastern Uganda bordering Kenya marked by chronic poverty and the poorest human development indicators in the country. Traditional dependence on semi-nomadiccattle-raising has been increasingly jeopardized. Extreme climate variability, amongst other factors, has made the region’s pastoralist and agro-pastoralist people highly vulnerable to food insecurity.

Climate warming during the past century has imposed recession of glaciers and perennial snow/ice patches along the entire Swedish Scandes. On the newly exposed forefields, subfossil wood remnants are being outwashed from beneath ice and snow bodies. In Scandinavia, this kind of detrital wood is a previously unused source of postglacial vegetation and climate history. The present study reports radiocarbon dates of a set of 78 wood samples, retrieved from three main sites, high above modern treelines and stretching along the Swedish Scandes.

The general trend of climatically-driven treeline advance is modified by regional, local and temporal variations. Treelines will not advance in a closed front parallel to the shift of any isotherm to higher elevations and more northern latitudes. The effects of varying topography on site conditions and the after-effects of historical disturbances by natural and anthropogenic factors may override the effects of slightly higher average temperatures. Moreover, the varying treeline-forming species respond in different ways to a changing climate.

This paper elaborates and visualizes processes recorded in a recent regional and multi-site study of elevational
treeline dynamics during the period 1915 to 2007 in the Swedish Scandes. The purpose is to give a concrete face of
the landscape transformation which is associated with the recorded treeline shifts. The main focus is on stand-level
structure of past and present treelines and the advance zones, where climate change elicited responses by Betula pubescens

Economist Sir Nicholas Stern warned that the global warming could cause major blow to the world economy than the two world wars and the crisis in the 1930s. But where are we in this process now and what can be expected in the near future and what opportunities we are to curb the negative effects and to slow down the global warming.

The upper treeline of Scots pine (Pinus sylvestris L.) is renowned as a sensitive indicator of climate change and variability. By use of megafossil tree remains, preserved exposed on the ground surface, treeline shift over the past millennium was investigated at multiple sites along the Scandes in northern Sweden. Difference in thermal level between the present and the Medieval period, about AD 1000-1200, is a central, although controversial, aspect concerning the detection and attribution of anthropogenic climate warming.
