We see a woman and a man looking at a long hand ax in the lab.


Archaeologists in Saudi Arabia have discovered what may be the world's largest prehistoric hand ax. The stone tool measures 20.2 inches (51.3 centimeters) long and, despite its size, is easily held with two hands, according to a statement.

An international team of researchers found the basalt hand ax on the Qurh Plain, just south of AlUla, a region in northwest Saudi Arabia. Both of the hand ax's sides have been sharpened, suggesting that it could have been employed for cutting or chopping. However, it's still unclear how the stone tool was used and which species, for instance Homo erectus or Homo sapiens, crafted it.

It's also unknown how old the tool is, as "the handaxe requires much more research to determine an accurate date," Ömer Can Aksoy, an archaeologist and the excavation's project director, told Live Science in an email. However, other tools found at the site may date to 200,000 years ago, according to the team's assessment of their form and characteristics, so it's possible that the hand ax dates also to the Lower or Middle Palaeolithic, Aksoy said.

Researchers nearly missed the enormous hand ax, which is 3.7 inches (9.5 cm) wide and 2.2 inches (5.7 cm) thick. "It was the last 15 minutes of our daily work and it was a hot day," Aksoy said. "Two of our team members found the giant handaxe lying over the surface of a sand dune."

After hearing the team members' calls, the rest of the crew joined them and then excavated the area in depth. "We recorded 13 more handaxes on the site," Aksoy said. "Each team member took off their yellow vests in order to highlight the locations of each find over the sand dune."

While the other newly found hand axes were similar in style, they were smaller in size. "After the initial excitement when we discovered this remarkable object we carried out an initial search to see if other similar sized objects had been found," Aksoy said. While the search for large hand axes continues, "this might be one of the longest," he said.

Surveys at Qurh Plain are ongoing. The 2023 field season, which lasts from October to December, is nearly over. Archaeological work is planned to start again in winter and spring 2024.

The Iron Age site of Casas del Turuñuelo was used repeatedly for ritualized animal sacrifice, according to a multidisciplinary study published November 22, 2023 in the open-access journal PLOS ONE by Mª Pilar Iborra Eres of the Institut Valencià de Conservació, Restauració i Investigació, Spain, Sebastián Celestino Pérez of Consejo Superior de Investigaciones Científicas, Spain, and their colleagues.

Archaeological sites with evidence of major animal sacrifices are rarely known from the Iron Age of the Mediterranean region, and there is a gap between information offered by written sources and by the archaeological record. This makes it difficult to establish a clear understanding of the patterns and protocols of this practice. In this study, researchers examine a well-preserved example of mass animal sacrifice from an Iron Age building in southwest Spain known as Casas del Turuñuelo, associated to Tartessos and dating toward the end of the 5th Century BCE.

The authors examined and dated 6770 bones belonging to 52 sacrificed animals which were buried in three sequential phases. The identified animals were predominantly adult horses, with smaller numbers of cattle and pigs and one dog. In the first two phases, skeletons were mostly complete and unaltered, but in the third phase, skeletons (except equids) show signs of having been processed for food, suggesting that some sort of meal accompanied this ritual. These data indicate that this space was used repeatedly over several years for sacrificial rituals whose practices and purposes varied.

This case study allows researchers to establish details about ritual protocols at this site, including the intentional selection of adult animals rather than young, and the importance of fire evidenced by the presence of burned plant and animal remains. Casas del Turuñuelo also exhibits unique features compared to other sites, such as the high abundance of sacrificed horses. This study advances efforts to contextualize ritual animal sacrifices across Europe.

The authors add: “This study highlights the role of mass animal sacrifices in the context of Iron Age European societies. Zooarchaeological, taphonomic and microstratigraphic investigations shed light on animal sacrifice practices and the Tartessian ritual behavior at the Iron Age site of Casas del Turuñuelo (Badajoz, Spain).”

Nitrous oxide (N2O) is not only one of the most important long-lived greenhouse gases but also the current main stratospheric ozone-depleting substance. China is among the top N2O-emitting countries, so it is important to identify and quantify N2O sources to support making mitigation strategies. However, existing national inventories focus on either single or short-term N2O sources, and fail to provide long-term and full-scale N2O profiles including both natural and anthropogenic sources.

The total N2O emissions in China were 2126.1 Gg N2O yr−1 for 2010–2020, with 18.2% and 81.8% from natural and anthropogenic sources, respectively (Figure 1). Agriculture was the largest N2O sources, accounting for 46.3 of the total emissions, among which 22.5% was caused by synthetic nitrogen fertilizer applications. Industry, energy, and waste accounted for 15.5%, 14.5%, and 5.4% of the total emissions, respectively, with adipic acid production, electricity, and wastewater treatment being their individual largest N2O sources.

Chinese N2O emissions increased from 889.6 Gg N2O yr-1 in 1980 to 2295.0 Gg N2O yr-1 in 2020, while agriculture made the largest contribution to this increase. However, this study revealed that agriculture N2O emissions declined steadily since the release of the Zero Growth in Fertilizer Plan in 2015 by the Chinese government. In the meantime, industrial and energetic sources exceeded agriculture and became the fastest-accelerating N2O sources in China due to the increasing demand for adipic acid and fossil fuels (Figure 2).

“This FAN 2020 dataset will provide up-to-date information for improving national N2O inventory and further support developing point-targeted mitigation policies. We think it will contribute to the global and national climate actions within the framework of SDG 13”, says Dr. Jing Wei from Sun Yat-sen University in Zhuhai, one of the leaders of this study.

Dr. Wenping Yuan and Dr. Jing Wei from Sun Yat-sen University, made the plan to produce a long-term dataset of full-scale N2O emissions in China and designed the experiment. Ms. Minqi Liang, a PhD candidate, Ms. Zheyan Zhou, a Master’s candidate, and Ms. Peiyang Ren, a PhD candidate at Sun Yat-sen University, collected the raw data and performed the calculation. All the authors contributed to the writing of the manuscript.

Gauging user benefits of multi-homing in platform economics

MULTI-HOMING VERSUS SINGLE-HOMING

Kyoto, Japan -- As with the business of logistics, where having multiple routes to deliver goods to the same destination raises reliability, network-dependent consumerism depends on multiple networks having a host computer with multiple connections operating in sync. 

With digital platforms for business becoming the norm, industry experience reminds us of the risks when relying on a single network and concentrating on only a few operators.  

A research group including Kyoto University studied the relationship between single-homing consumers -- who use only one particular platform -- and multi-homing consumers. The team presented a new framework demonstrating whether proportionately more multi-homing consumers lead to significant efficiency gains when integrating two business platforms.

"Our study is related to the economics of imperfect competition, a field covering various market-related issues that has become increasingly important as information and communication technology advances," says first author Takanori Adachi of KyotoU's Graduate School of Management and Graduate School of Economics. 

The platform used in a single-homing situation naturally takes on a dominant role for consumers. However, there is a growing tendency to focus on the multi-homing's need for policy guidance when considering the nature of digital regulation and policy because, proportionately, more consumers use multiple platforms. 

"In addition, an increase in the degree of multi-homing needs a more considerable reduction in the cost for allowing a business consolidation. It also creates higher barriers to entry for new platform firms," explains Mark Trembley of the University of Nevada, Las Vegas. 

"We must note, therefore, under multi-homing situations, competition authorities may need to be more cautious about potential harms of platform mergers and entry barriers," adds Susumu Sato of Hitotsubashi University. 

Researchers must often make do with scant data availability on platform businesses. 

"We were delighted that our deductive arguments based on economic theory models and public databases, such as the one used in this study, effectively provided us a clearer picture of how platform economics performs in the real world," says Adachi.

Experts have delivered a sweeping prescription to governments, civil society and industry for a globally coordinated approach to the responsible sourcing of raw materials needed to achieve a circular green economy.

In a report, the four-year EU-funded RE-SOURCING project proposes adopting the global vision of a circular economy and reduced resource consumption by 2050 and outlines a series of interim milestones and targets for three key industrial sectors: renewable energy, mobility, and electric and electronic equipment. 

The report (at https://bit.ly/3uqXlqT from 22 November) acknowledges several firms and governments are showing leadership in responsible sourcing to address troubling global environmental, social and economic issues, including:

  • Biodiversity and habitat protection, land, air and water pollution, climate change
  • Access to clean water, air & health care, gender equality, human rights, respecting land rights, labour rights, and safeguarding the artisanal and small-scale miners
  • Corruption and money laundering, promoting sustainable growth and development, and enabling national / local industrial development

At the same time, they underline that “the corporate behaviour that existed in the preceding century is no longer acceptable. More responsible and sustainable practices need to be undertaken and evidenced.”

Adds the report that the underlying message from stakeholders across the board is that “industry and its supply chains must incorporate and reflect societal values in their operations and business management” and “power imbalances, where they impede the ability of a group to affect the decisions that impact them, need to be addressed.”

Lead author Masuma Farooki says achieving responsible sourcing begins with a universally accepted definition and commonly agreed targets for 2050, proposing the following in the report: 

1: Circular economy and decreased resource consumption

2: Meeting the Paris Agreement climate goals and environmental sustainability

3: Social sustainability and responsible production

4: Responsible procurement

5: Level-playing field and international cooperation

International cooperation, the report notes, means helping companies, regions, and countries improve practices and achieve agreed standards. A level playing field “is paramount for achieving all other targets.”

The report strongly underlines the need to address the power imbalance between local communities, workers and other affected stakeholders in decision-making, enabling their meaningful participation in decision-making.

Transparency is also fundamental.  Consumers need to know how elements of the products they buy are derived, with adequate information to choose sustainably sourced products.

Key points in the report include:

  • Companies should not pass along to communities and workers the costs of negative impacts, such as pollution and land degradation
  • To reduce corruption and the financing of violence that have often accompanied extractive activity, transparency is needed in financial payments and material flows in supply chains
  • Standards and guidelines based on multi-stakeholder consultations, as well as certification schemes, and government regulations and legislation, are needed, citing several examples from the US and Europe

Among many recommendations to policymakers:

  • Strengthen international cooperation to develop harmonized mining standards for responsible extraction
  • Enable responsible mining in Europe (no more ‘burden-shifting’ to other regions)
  • Update mining regulations based on existing voluntary certification schemes
  • Eco-design policies for solar PVs and wind turbines
  • Lower taxes on, and give preference to, goods manufactured with higher social and environmental standards

Recycling: 

  • Support recycling activities and create markets for secondary raw materials
  • Require Life Cycle Assessments for all new technologies/products
  • Develop and implement environmental regulations for wind turbine and solar PV manufacturing and recycling

Wider Policy: 

  • Harmonize environmental policies of EU Member States and coordinate responsible sourcing reporting criteria
  • Protect human rights defenders and support civil society capacity building
  • Make supply chain due diligence mandatory for all
  • Ensure that raw materials and products imported from outside the EU fulfill the same sustainability requirements as operations inside the EU

Recommendations for industry include:

Mining: 

  • Fleet electrification and decreased energy intensity
  • Plan for mine closure from the beginning of project development
  • Support local procurement 

Manufacturing: 

  • Include eco-design from the beginning of product development to improve recyclability
  • Include ‘social life cycle assessment’ in product development
  • Firmly eliminate modern slavery and forced labour in the supply chain of solar PV and wind turbines

Recycling: 

  • Improve collaboration between supply chain stages, research, and academia to substitute non-recyclable materials
  • Cooperate with other sectors to improve reuse of non-recyclable materials. 

Corporate strategies: 

  • Environment and climate reporting, including greenhouse gas accounting and reporting for the entire supply chain
  • Tailor-made climate protection projects 
  • International application of environmental and social standards

The report provides specific roadmaps and recommendations for policymakers and companies in the renewable energy, mobility sector, and the electronic product sectors.

It also takes a special look at three regions: Latin America, Africa, and China.

Latin American mining projects can face particularly strong opposition from local communities. According to the Environmental Justice Atlas (EJAtlas 2023), 45% of reported conflicts worldwide are in Latin America, where projects are often located near sensitive, biodiverse ecosystems, many of which are home to vulnerable communities. 

A key regional priority, therefore, is “strengthening of social capital and civil society trust in the mining sector with focus on the local communities.”

African regional challenges include “trustful and transparent collaboration” by industry, local governments, and others. “If the mining sector, communities, supply chain and governments work together, the outlook for the industry on the continent will be bright”

Among other key considerations for Africa: supporting and improving artisanal and small-scale mining operations, which plays a crucial role in obtaining many raw materials essential for the green transition. 

China, meanwhile, dominates the critical green-energy technology minerals supply chain with rising investments abroad. A recent report associated China, however, with over 100 human rights abuses, environmental harms, workers’ rights violations and other allegations over the past two years in Indonesia, Peru, Congo, Myanmar, Zimbabwe and other countries.

It also notes China’s creation of guidelines to align companies’ due diligence with international standards.

The report adds that similar allegations are made against mining operations linked to Canadian, USA, UK, Australian and European companies and investors. 

In the end, the report cautions, “the findings just underline growing concerns that the green transition to renewable energy is repeating unjust business practices that have long dominated fossil-fuel and mineral extractions.”

Comments

  • Stefanie Degreif, OEKO Institute, Germany: “Significant and systemic changes are needed now and over the next decades to achieve climate targets and make the lithium-ion battery chain more responsible and sustainable. There is no time to waste - we need to act now! Changes are needed and cannot be postponed to the next generation or next legislation period
  • Andreas Endl, Vienna University of Economics and Business (WU), Austria: “Over the course of the last four years, we investigated closely and informed decision makers about the fast-moving and immensely dynamic discourse on responsible sourcing. While progress has been made on many fronts with stricter legislation and successful business cases, we still have to go a long way to improve the livelihoods of affected people and respect the integrity of the environment” 
  • Michael Tost, Montanuniversität Leoben, Austria: “A sustainable energy transition can be successfully achieved only if all actors including policy makers, industry, and civil society realize their responsibility in openly discussing and engaging with affected communities to create trust.”
  • Shahrzad Manoochehri, World Resources Forum Association, Switzerland: “Due to the complexity and interconnected nature of mineral value chains, achieving responsible sourcing at a global level requires mutual understanding, a fair competitive environment, and the establishment of shared common goals that are respected by all stakeholders across different regions.”

Background

In 1998, amid mounting internal and external pressures, nine international mining companies united to establish the Global Mining Initiative. Their goal was to understand and transform their operations per societal expectations. A surge in community discord, violent incidents, opposition to mining projects, accusations of corruption and bribery, and the threat of nationalization by host governments had pushed these companies to act. Reputational damage and share price concerns further fueled their drive for change.

Simultaneously, international policy and politics began to emphasize securing a sustainable future and acknowledging the dire consequences of environmental damage.

Consumer awareness and citizenship advocacy also started pushing for more sustainable public policies, making the environmental agenda a central political topic. Businesses and investors, initially slowly and later in growing numbers, began to prioritize sustainable sourcing practices within their supply chains. 

Addressing corruption and bribery in the extractive sector became a significant government issue. This collective but not necessarily coordinated movement aimed to transform behaviours in the extractive sector and its associated supply chains.

Today, the green transition and the shift toward renewable energy, heavily relies on mineral consumption. However, the adverse impacts on ecosystems, human rights, and economic inequality are no longer acceptable. The mining sector and its associated supply chains are steadfastly committed to becoming more responsible in their operations, with sustainability as a core objective.

Responsible sourcing (RS) practices have emerged as a vital tool in achieving these objectives and minimizing negative impacts within mineral supply chains. By 2023, RS is no longer a distant ideal but a practical reality for businesses and policymakers, and it is increasingly demanded by Civil Society Organizations (CSOs). 

To tackle the growing challenge of implementing RS, the RE-SOURCING Global Stakeholder Platform was initiated in 2020. Funded under the European Union's Horizon 2020 program, this four-year project, coordinated by the Institute for Managing Sustainability at the Vienna University of Economics and Business Administration, assembled international partners within and outside the EU to create the RE-SOURCING Platform, including OEKO Institut (Germany), World Resources Forum Association (Switzerland), Montanuniversität Leoben (Austria), Tallinn University of Technology (Estonia), MineHutte Intelligence (UK), SOMO (Netherlands), WWF (Germany), EIT Raw Materials (Germany), Luleå University of Technology (Sweden, AHK Business Center (Chile) and SRK Consulting (South Africa). 

The project's vision was to advance the understanding of RS as a mandatory requirement in mineral supply chains among EU and international stakeholders. This involved fostering the development of a globally accepted definition of RS, facilitating the implementation of RS practices through knowledge exchange, creating visions and roadmaps and Good Practice Guidance for three key EU sectors –  renewable energy, mobility, and electronics – and advocating for RS in international political arenas.

The RE-SOURCING Project focused on:

  • Facilitating a globally accepted definition of RS.
  • Brainstorming incentives to support RS and responsible business conduct
  • Enabling exchanges of information and promoting RS among stakeholders
  • Fostering the emergence of RS in international political fora
  • Supporting the European Innovation Partnership on Raw Materials

Outputs of the RE-SOURCING Project were tailored to:

EU and international business stakeholders:

  • Increased capacity of decision-makers to implement responsible business conduct.
  • Better understanding and awareness of RS in three key sectors: renewable energy, mobility, and electrical and electronic equipment.
  • Facilitated implementation of lasting and stable sectoral framework conditions for RS.

EU policymakers:

  • Increased capacity for RS policy design and implementation.
  • Innovative ideas on policy recommendations for stimulating RS in the private sector.
  • Better understanding and awareness of RS in three key sectors: renewable energy, mobility, and electrical and electronic equipment.

Civil society:

  • Integration of sustainable development and environmental agendas into the RS discourse.
  • Establishment of a global level playing field for RS in international political fora and business agendas.
  • Enhanced understanding and awareness of RS in three key sectors: renewable energy, mobility, and electrical electronic equipment.

Throughout the project, numerous reports, executive summaries, policy briefings, Good Practice Guidance, workshops, events, and webinars were conducted, ultimately informing a final report. 

The move to responsible sourcing is now an integral part of the global conversation on sustainability, and it's reshaping the way industries operate and impact the world.

According to the report: “The proposed RS framework is adaptable and allows for diverse pathways based on regional priorities. It aims to coordinate and consolidate various RS approaches without losing their unique features, providing a common destination while accommodating different speeds of progress.”

The report presents “a Rights-Based Approach framework for responsible sourcing in mineral supply chains, aiming to consolidate and align existing approaches, promote international cooperation, and ensure equitable distribution of benefits while accommodating regional variations.”
