We compared seasonal changes in food availability between Maya subsistence farmers and modern householders who pursue cash earnings in rural Yucatan. Modern households encourage the substitution of vegetable for animal protein that severely affects them during scarcity season, particularly in small towns. Subsistence households have increased their legume intake when food was scarce. Seasonality had the largest effect on fruit availability. Unable to obtain enough protein and micronutrient rich foods when meats, fruits and vegetables become scarce, modern households make up for it by purchasing more fats and sugars, particularly in large towns with many grocery stores.

The question of how the complexity of water governance may be understood beyond a heuristic concept remains unanswered. In this paper, we propose a Water Governance Complexity Framework to address the complexity of water governance. Through a literature review, rapid surveys, and 79 semi-structured interviews, we propose how this framework may be operationalized using different proxies and by applying it to the case of the water supply system for domestic use in Oaxaca, Mexico. In places such as the rural communities of Oaxaca, where the state plays a partially absent role in the water supply, we found legal pluralism and diverse formal and informal stakeholders in a multi-level structure. At the local level, four modes of governance were identified, resulting from seven institutional change trajectories. These trajectories result from linear (alignment) and non-linear (resistance and adaptation) interactions between local, state, and national institutions over different periods. We provide a pragmatic framework to understand complexity through the organization and historical configurations of water governance that may be applied globally, providing a necessary starting point and solid foundation for the creation of new water policies and law reforms or transitions to the polycentric governance model to ensure the human right to water and sanitation.

To analyze the process of seeking tuberculosis care and this process's impact on treatment adherence in the Mexican state of Chiapas, given that the two primary factors in successful tuberculosis (TB) control programs are early diagnosis and adherence to TB treatment. We conducted a qualitative study using group interviews with 11 groups of patients in three of the nine socioeconomic regions of the state of the Chiapas (Altos, Centro, and Fronteriza). The patients applied a variety of approaches in seeking care. The patients reported considerable delays in diagnosis due to problems that the patients themselves had and because of shortcomings in the care they received from the formal health care system. The treatment options that they followed were the result of their perceptions of the causes of TB and of the variety of traditional medical practices accepted in their communities. The lack of knowledge about TB encourages people to consider various alternatives for their care. Tuberculosis control in Chiapas requires an optimal utilization of the health services that exist in the state as well as a program of health education. TB control in Chiapas must take into account the social, cultural, and economic reality of the population.
