We began with a series of questions that participants had about oases, posed to thegroup to be answered in turn or to lead to further research:
• How are tinajas biologically connected, and when they go dry, how are they?
• Why is there no human evidence around many of the tinajas, especially those long-lived tinajas at Angel de la Guarda?
• How do we protect groundwater flows to support oasis springs?
• What are the hydrological dynamics of oases?
• ¿Como conservan los flujos del agua subteranea?
• How do we protect these spaces that are small in area and large in importance?
• ¿Que tipo de oasis son más vulnerables?
• ¿Como van a afectar los oasis los cambios climáticos?
• ¿Como están los aquíferos de la peninsula? ¿ Cuanta agua entra y sale?
• What has been the impact of the militarization of the border on oases?
• How do we engage students, scientists, and citizens? • How are the ground and surface waters connected?
• What are the most effective methods for oasis conservation and at what scale?
• We need to remember that oases exist at different scales, from the sources of water inside cacti to the large freshwater lagoons of the peninsula.
• They are also cultural landscapes as much as they are biological landscapes—even of the tinajas have been created by humans.
• There was a proposal to UNESCO to make a World Heritage Site of all of the peninsular oases, as landscapes transformed by humans for long time periods and allow for the long-term coexistence of humans.
• Oases also serve as wildlife habitat, and planning and management strategies are to consider– Hay muchos animales que son adaptadas a paisajes humanos,como la ardilla negra
• Mucha economía depende de los oasis
• Ahora la extracción de agua tiene un impacto en los oasis
• Potencial de reusa o reinyección de agua
• Hay 4 ecosistemas que sustentan la mayoria de la vida en la peninsula—alta montaña, oasis, manglares-estuaries, esteros-costeras. También hay oasis en el golfo, “mounts” islas bajo el agua.
• Use of technology to promote water efficiency
• Careful long-term management (photo comparison)
• Some of the oases in Sonora are being managed for illegal drug production
• Tourism and its impacts on oases
• These spaces are not at the top of the priority list, and they should be—we might soon be fighting over water
• Oasis as resilient spaces
• Scientists such as Jorge Ramírez, Karl Flessa and Walter Daessle are studying the aquifers of the peninsula.
• Need to develop local management strategies, governance at different scales.
• Long term studies of adaptation
• The need to develop sustainable, grassroots organizations around these oases.
• The disconnect between the natural resource and the minds of the people—drillingpractices far from the oasis can affect spring flow.
• Small mountain oases might be sustainable in the long-term because they have been cultivated for hundreds of years and have still retained much of original character.
• These sites provide environmental services.
• People in the cities depend on these small communities in many ways.
• The need to collaborate with decision makers and groups that are already working in the oases.
