Rangelands Atlas
Rangelands can be described as land on which the vegetation
is predominantly grasses, grass-like plants, forbs or shrubs,
and often with trees that are grazed or have the potential to be
grazed by livestock and wildlife. They are diverse in their vegetation
driven by highly fluctuating rainfall, temperature and other climate
phenomena, and habitat for a wide range of wildlife, many species
of which are found nowhere else. Rangelands store vast amounts of
carbon and either originate or serve as freshwater catchment areas for
most of the worldâs largest rivers and wetlands. Rangelands are home
to millions of people, from pastoralists to hunter-gatherers to ranchers
to conservationists. Rangelands feed millions of people worldwide.
Rangelands have significant cultural and aesthetic value too, and for
many, are places of inspiration and beauty.
This Rangelands Atlas has been developed to document and raise
awareness on the enormous environmental, economic and social value
of rangelands as well as their different ecosystems. It highlights many of
the changes taking place in rangelands due to climate change, land use
and conversion trends, investments and other changes: of most concern
is the predicted trends of climate change and biodiversity loss, which
will have significant impacts on some rangeland ecosystems.
The spatial mapping of rangelands was produced by focusing on
seven of the 14 global biomes categorised by WWF in their mapping of
terrestrial ecoregions around the world. These seven biomes include
different types of mainly dryland grasslands, savannas, shrublands and
forests, together with wetter and colder biomes such as tundra. Though
this mapping does not take into account actual land use and other
changes that have taken place on the ground, it is a useful starting
point for identifying, documenting and raising awareness on the overall
characteristics of rangelands, their contribution to livestock and other
food production, ecosystem services, conservation and the broader
trends of change taking place.
The Atlas also highlights significant data gaps in rangelands, which
have seen proportionately less investment in this regard than other
land uses and ecosystems. The spatial map of rangelands is combined
with other existing global datasets on different themes, to produce a
mapping of that data âfor rangelands.â
Each entry is presented with a short explanation of the map, some key figures produced from the big data that produced the map, a story from
the field adding a taste of a local experience and/or perspective, and some explanation of terminologies used in the map as required. We are
reliant on the accuracy of the datasets we have accessed: the data have not been verified at regional, country or local level, and therefore is only an indicator of broad and estimated figures and trends
âTop-Down-Bottom-Upâ Methodology as a Common Approach to Defining Bespoke Sets of Sustainability Assessment Criteria for the Built Environment
YesThe top-down-bottom-up (TDBU) methodology for defining bespoke sets of sustainability criteria for specific civil engineering project types is introduced and discussed. The need to define sustainability criteria for specific civil engineering project types occurs mainly in one or both of the following cases: (1) when a more comprehensive and indicative assessment of the sustainability of the project type in question is required; and/or (2) there is no readily available bespoke sustainability assessment tool, or set of criteria, for assessing the sustainability of the project type. The construction of roads, buildings, airports, tunnels, dams, flood banks, bridges, water supply, and sewage systems and their supporting systems are considered to be unique civil engineering/infrastructure project types. The normative definition of sustainable civil engineering/infrastructure projects and the framework for assessing its sustainability is defined and provided by the authors. An example of the TDBU methodology being applied to define sustainability criteria for transport noise reducing devices is presented and discussed. The end result of applying the methodology is a systematically researched and industry validated set of criteria that denotes assessing the sustainability of the civil engineering/infrastructure project type. The paper concludes that the top-down-bottom-up will support stakeholders and managers involved in assessing sustainability to consider all major research methods to define general and unique sustainability criteria to assess and so maximize sustainability

Trade and the environment: a critical assessment and some suggestions for reconciliation
This article critically assesses three ways in which trade might harm the environment. First, trade liberalization might exacerbate existing levels of resource depletion and environmental pollution. Second, open borders might allow companies to migrate to âpollution havens,â thus undermining high environmental standards in host countries. Third, the dispute settlement system of the World Trade Organization (WTO) might favor trade over environmental interests in case of conflict. It is shown that although trade liberalization can lead to an increase in environmental degradation, pollution havens are not a statistically significant phenomenon. As concerns aimed measures at domestic environmental protection, the dispute settlement system in the WTO is not biased against environmental interests. The relationship is more complicated with respect to measures aimed at extrajurisdictional environmental protection and with respect to trade restrictions for health reasons under the Agreement on Sanitary and Phytosanitary Measures. The article concludes with some constructive suggestions on how trade and the environment can be reconciled in future trade negotiations

Pastoralism: A sustainable and nature-positive production system
This Rangelands Atlas is a collaborative initiative of the ILRI, IUCN, FAO, of the United Nations, WWF, UNEP, and the global Rangelands Initiative of ILC. This Rangelands Atlas has been developed to document and raise awareness on the enormous environmental, economic and social value of rangelands as well as their different ecosystems. Drawing on publicly available data, this Atlas provides a preliminary set of maps, which will be added to over time. These maps illustrate the complex nature of rangelands found around the world. Furthermore, the Rangeland Atlas reflects a strengthening, global movement to protect, restore and appropriately invest in rangelands. The Rangelands Atlas is available online at: www.rangelandsdata.org/atlasThis film shows how pastoralism is a sustainable and nature-positive production system in Italy, contributing to economies, societies and the environment. Filmed in three different areas of the country - Sardinia, the Italian Alps, and Abruzzo - it brings together the opinions and views of different stakeholders on benefits, challenges and opportunities, including for the future.

Interdependence
How should we respond to the increasingly dense bundle of economic, cultural and ecological interconnections that span the globe and stretch into the future? What kinds of ethical and public engagements are demanded of researchers who work on global environmental, economic and social issues? The term interdependence may provide a powerful framework for advancing thinking and debate both within academia and among wider publics in relation to these questions. Members of the Open University's Geography Department have been working with partners to build the Interdependence Day project. The project combines research, cultural work, communications and public participation in an attempt to make sense of our responsibilities to people distant in space and time, and to the nonhuman natural world. This article reviews nearly a century of deployments of the term interdependence in political and academic writing, introduces the distinctive work that might be done with the term in the critical social sciences, and outlines the Interdependence Day project
