The Research

Around 8,000 years ago, Central Portugal underwent a dramatic shift in lifestyles from hunting and gathering to farming and herding (e.g., Bailey and Milner, 2002; Erlandson, 2001; Renouf, 1998). Globally, this transition was much more than a mere shift in where food came from. It was a change in the way people lived on the land, which, in turn, allowed them to stay in one place longer than previously possible. That led to shifts to more permanent housing, the emergence of true villages, and increased social structure. In short, this transition is about when we became “us.”

Usually thought of as one culture (the “more advanced” agriculturalist) replacing another (the “more primitive” hunter/ gatherers), there is increasing evidence to suggest these cultural systems existed at the same time and place (Bicho et al., 2013; Price, 2015).

The Mesolithic-Neolithic transition remains one of the most controversial issues in prehistory archaeology, attracting significant archaeological debate and extensive research. The common-held belief is that hunter-gatherers disappeared from Central Portugal around 7,000 years ago, and later, farmers and herders settled in the area. But now, archaeologists are uncovering clues contradicting this.

By analyzing bone tools, shells (and other evidence of food types consumed), ornaments, and human remains, researchers will trace the transition between these periods to better understand the complex changes not only in technology and subsistence but also in how people thought about themselves and the world around them, as well as the nature of their social interactions.

Due to its diversity of artifact assemblages, excellent faunal and human bone preservation, evidence for multiple site functions, and the presence of a newly discovered wet context (e.g., Bokelmann, 2012; Conneller et al., 2009; Milner et al., 2011) Cabeço da Amoreira and Cabeço da Arruda are an ideal location to study the Mesolithic hunter-gatherers and their probable integration into the newly arrived exogenous Neolithic societies coming from the Mediterranean Sea. At the same time, researchers will be looking to understand potential climatic drivers that have precipitated this shift and the impact of these food-producing societies on the natural environment, regional ecology, and cultural background.

Research Aims

Researchers seek to understand how individuals changed culturally and physically, how tools and technologies changed during this time, and how burial practices, rituals, and land use differed between the Mesolithic and Neolithic populations.

Researchers have already discovered several sets of human burials at the project site—key findings that have provided insights into the genetic continuity at the Mesolithic-Neolithic transition, enabling a better understanding of past human diets and mobility. 

The goals of understanding and defining the Mesolithic-Neolithic transition process in the region are grounded in providing answers to the following set of research questions: 

  1. Is it possible to identify cultural and physical alterations in the local population based on DNA and diet? And how are these possibly related to population movement and integration?
  2. Was there a differential use among Mesolithic and Neolithic populations (e.g., burial contexts, funerary rituals, prestige items, and land use)?
  3. What were the changes and/or continuities in technology?
  4. How did the apparent changes in subsistence strategies impact social changes and the regional ecology?

How You Will Help

Citizen scientists will be involved in both excavation and laboratory activities, including the following tasks:

Excavation:

  • digging
  • total station and data recording
  • software operation
  • sediment screening
  • sample collection

Laboratory Activities:

  • washing, sorting, and labeling archaeological materials
  • data entry and management
  • floatation and processing of paleobotany samples

Specialists in different research areas will conduct sample analysis during laboratory work hours. Citizen scientists are encouraged to watch and experiment with these tasks. All processes will be accompanied by in-depth explanations of their importance to the project and the preservation of past cultural heritage. 

On some teams, volunteers may also help develop educational materials and participate in public lectures and other outreach activities to raise awareness about the project and the importance of prehistoric archaeology.

Life in the Field

Each day, the team will rise early and prepare for the field. After breakfast, everyone will be driven to the research site to receive a daily briefing regarding the activities to be carried out that day—both in the field and at the laboratory.

DAILY ACTIVITIES

Weather and research needs can lead to changes in the daily schedule. We appreciate your cooperation and understanding.

Excavation activities will take place during the morning, from 7:30 a.m. to 12:30 p.m. During the excavation, participants are encouraged to ask questions about the materials and techniques used. Occasionally, the team may be joined by local university and high school students who are there to learn. You will receive training on the activities and the basic tools and software used daily. 

After morning fieldwork, participants will return to the accommodations, where they will prepare their lunches using the provided supplies. Following this short rest break, the team will walk about 5 minutes (approx. 100 meters) to the laboratory for afternoon work. 

There will be time to rest, socialize, and discuss the day’s work in the evenings. Most nights, the team will enjoy dinner at a local restaurant (chosen in advance by field staff). On a couple of evenings, the group will dine on-site at the palace (pizza night or similar!

Accommodations and Food

* Please note that not every expedition has couples’ or singles' accommodations available. Please call or email Earthwatch to check availability before reserving your space(s) on the team.

SLEEPING

Earthwatch teams will stay at the Palace of Muge Estate (also known as ‘Casa Cadaval’), the historic home on the property where the research site is located. In the palace, rooms will be shared between two volunteers of the same gender, and teams will share multiple bathrooms in one wing of the home. There may be rooms available for pairs with advanced notice. Sheets, towels, pillows, and blankets will all be provided. A small table fan is provided, but please note that the palace rooms are not air-conditioned.

The family estate is home to Teresa Schonborn, Countess of Schonborn, and Wiesentheid, the House's Chairman of the Board of Directors. Countess Teresa Schonborn is a friend and colleague of the research team, a project collaborator, and passionate about archeology. The home is a private residence and a historical landmark. This housing is a truly special and unique experience.

* Earthwatch will honor each person’s assertion of gender identity respectfully and without judgment. For both teen and adult teams, where logistics dictate single-sex accommodations or other facilities, participant placements will be made in accordance with the gender identity the participant specified on their Earthwatch Participant form and/or preferences indicated in discussions with Earthwatch.

BATHROOMS

The bathrooms are shared and have conventional flush toilets and hot showers.

PERSONAL COMMUNICATIONS

All participants with international plans can be reached through mobile phones at any time. Because mobile networks are available at the sites, e-mail and Skype can also be used.

All project staff are equipped with mobile phones with a mobile network.

Please note: Earthwatch encourages volunteers to minimize outgoing calls and immerse themselves in the experience; likewise, family and friends should restrict calls to urgent messages only. Emergency communications will be prioritized.

DISTANCE TO THE FIELD SITE

The distance between the accommodations and the field site is very short, with travel time less than 10 minutes by van. The laboratory facilities are about a 5-minute walk (approx. 100 meters) from the accommodations.

FOOD AND WATER

The teams will eat local Portuguese cuisine, including fresh items. Soups and stews are typical due to the presence of ancient convents and monasteries where they originate. Volunteers will prepare their breakfasts, lunches, and snacks at the accommodations. Drinking water will be provided. Fresh fruits and energy bars are available for snacks. Dinner will be arranged at local restaurants or in the palace courtyard.

TYPICAL MEALS

The following are examples of foods you may find in the field. Variety depends on availability. We appreciate your flexibility.

  • Breakfast: Bread, cheese, eggs, spreads (peanut butter), fresh fruit, coffee, tea
  • Lunch: Sandwiches, deli meat, cheese, spreads (peanut butter), canned fish, vegetable salads, soft drinks
  • Dinner: Meat, grilled fish, fresh vegetables, a variety of stews and soups
  • Desserts: Local Portuguese desserts
  • Beverages: Water, coffee, juice, soft drinks
SPECIAL DIETARY REQUIREMENTS

Please alert Earthwatch to any special dietary requirements (e.g., diabetes, lactose intolerance, nut or other food allergies, vegetarian or vegan diets) as soon as possible and note them in the space on your volunteer forms. 

Vegetarians and lactose intolerant diets can be accommodated on this project if volunteers are flexible. Vegan diets and kosher diets are rather difficult to accommodate. If you have a special diet, it is recommended that you bring some supplemental snacks.

Project Conditions

The following information is as accurate as possible, but please remember that conditions may change.

The project area is Lezíria Ribatejana, located on the plain of the Tagus River.

The Ribatejo region, where Muge shell middens are located, is a transition zone between two major ecosystems: Atlantic (to the north) and Mediterranean (to the south). Because of this ecosystem complexity, the region is home to diverse flora and fauna. The native vegetation of this area is usually cork-oak woods, myrtles, and shrubs of oaks. Grape vines dominate. However, other species are also present, including olive and fruit trees (e.g., pear, apple, quince, peach, orange, lemon, and fig). The herbaceous vegetation mainly comprises ruderal and nitrophilous species typical of agro-ecosystems. Trees surround the site, and it is not unusual to see local fauna wandering around—including small herbivores like rabbits or hares, birds of prey and herons, and farm animals that live on the property (cows, horses, and donkeys).

GENERAL CONDITIONS

Please visit Wunderground.com and search for your project location for weather and region-specific information.

Summer wildfires impact mainland Portugal on an annual basis. All participants are advised to monitor local media for wildfire warnings to avoid dangerous areas while traveling in Portugal. You may track updates to high-risk areas using the Risk Level Map. To view the project site region in this map, select the Santarém District and the county of Salveterra de Magos. Should there be any foreseen impacts on your expedition, you will be notified by Earthwatch.

Project Risks and Precautions

TRANSPORTATION

As in any country, transport is a risk. All vans and cars will be fitted with seatbelts, and all passengers must wear them whenever the vehicle is in motion. Only experienced drivers will drive vehicles. Each vehicle will contain a first-aid kit and a cell phone for communication. Participants may not drive, even their own cars, during the project.

WALKING

Participants are required to engage in demanding physical activities, including walking over uneven terrain. Project staff will review the participants’ physical abilities and adjust the group's pace as much as possible to accommodate their needs. Due to the variable terrain, individuals with severe mobility restrictions may not be able to be accommodated.

CLIMATE/WEATHER

The region can be very hot in August and September. Temperatures average 84–91°F/29–33°C at the peak of the day but can occasionally exceed 104°F (40°C). The evenings are cooler, with temperatures dropping to around 63º–69ºF/17º–20ºC. Participants must be able to tolerate long periods of sun exposure during the summer months. Participants should take measures to avoid dehydration and sun exposure, such as drinking water throughout the day, covering up with full-length trousers and shirts, and wearing sunglasses and a hat with a generous brim. 

Wildfires are common in Portugal in the summer months; however, the national civil protection system has made significant strides in improving its firefighting capabilities and implementing preventive measures. Participants will be instructed on evacuation routes in the event of a fire at the accommodations or field sites. All participants are advised to monitor local media for wildfire warnings to avoid dangerous areas while traveling in Portugal. You may track updates to high-risk areas using the Risk Level Map. To view the project site region in this map, select the Santarém District and the county of Salveterra de Magos.

DEHYDRATION

Participants will be reminded to drink plenty of water throughout the day and to bring at least two liters of water into the field each day; to wear high-factor sunscreen and appropriate clothing, including sunglasses and a wide-brimmed hat; to not overwork when jet lagged or tired, and to inform a staff member when feeling tired or ill. The team will always take regular breaks as needed and monitor participants for general health.

ANIMALS & PLANTS

Due to the area's large number of trees, plants, and insects, we advise citizen scientists who suffer from pollen/insect allergies to bring appropriate medication. Information will be provided before the program to ensure proper medical awareness, and a prior review of allergies listed in participant forms will be undertaken by field staff. A diverse array of wild animals inhabits the Santarém region, most harmless. While encounters with wild animals are relatively rare, it is crucial to be cautious when exploring the region's woodlands, respecting wildlife habitats, and maintaining a safe distance. Remember, appreciating wildlife from a distance and promoting conservation efforts are essential for a harmonious coexistence between humans and the diverse animal species of the region.

PROJECT TASKS/EQUIPMENT

Instruction will be provided on proper excavation technique and proper inspection of equipment to ensure safety. Adequate protective personal equipment (i.e., work gloves, face masks, etc.) should be provided by each participant. The project will provide kneeling pads for participant use. 

COVID-19 DISEASE RISKS 

COVID-19 remains an evolving risk to communities and individuals around the world. 

Earthwatch strongly encourages you to stay up to date with your vaccinations, including receiving booster doses if available, and to continue to take steps to limit your exposure before your program, such as wearing a mask during travel and frequently washing your hands. Persons with a higher risk of severe illness from COVID-19 should consult with their healthcare provider before participation.

If you, or another person on site, display symptoms of illness or test positive for COVID-19, you may be required to wear a mask, test for COVID-19, seek medical advice, isolate/quarantine on- or off-site, cease or limit participation in program activities, and/or take other precautions. If local conditions or recommendations from authorities change, additional requirements may be implemented.  

If you must isolate or depart from a program due to COVID-19 or other illness, you will not be entitled to a refund of the contribution for the program, nor any expenses resulting from your participation in the program or a disruption of your travel plans. We strongly encourage you to purchase travel insurance that will cover this eventuality.
