In a few days, a glass of nutrient-rich water from a pond will turn a vibrant green. The green color is caused by microalgae, which are microscopic single-celled organisms that float freely in water. These organisms multiply rapidly when given sunlight, carbon dioxide, and water that is rich in organic waste or fertilizer washed from fields. Algae don't store their energy in starch, as plants do, but are instead full of vegetable oil - making them the equivalent of "green gold." In recent decades, there have been several cycles of interest to be able to exploit these organisms. Researchers have...

But there's a risk associated with it. These massive agricultural investments, which produce food and cash crops that are exported, could result in the loss of land rights local to the area and access. It could also be a threat to the sovereignty of food, which is the power of the people to control the distribution and production of food. In all land use uses, there are positive and negative impacts and outcomes that the authorities and communities must consider during the negotiations of these agreements. It is generally believed that the effects of these investment decisions on family nutrition security...

The men and women in this group are part of a group that an anthropologist Delphine Corteel as well as sociologist Stephane Le Lay ( ERES 2011,) have described as "waste workers". Despite their long and exhausting job, they are still marginalized from Moroccan society due to the dirtiness of their work, as well as their living areas. They live in the fringes of urban areas that are legal, as well as in slums and improvised homes that are frequently demolished or threatened by urban and real estate projects. When they are working on street areas, these people are frequently victimized...

  In a study that I conducted recently, I came across that the amount of children living with their grandparents and parents, which is what Demographers refer to as a family of three generations, has more than doubled over the last two decades. Why is this happening? Is it a positive idea or a bad one? The answer is complex. The reasons behind the trend can be as wide as social factors, ranging from the decline in the rate of marriage - and specific family situations, such as the loss of a parent's position. This is a trend worth studying...

My own experiences inspired me to examine the lifestyles of people of Afro-Caribbean origin, South Asians, and Chinese people living in Canada's Greater Toronto Area of Canada. The Chinese have a massive appetite for bok choys, Chinese eggplant, and gailan (also called Chinese broccoli). The South Asians are awestruck by okra, bitter melon, and even eggplant. People who are of African descendants tend to enjoy amaranth as well as okra (a leafy, green plant) and sometimes substitute the former with spinach due to the shortage. The fascinating thing about the groups mentioned above is that they have lots of foods in common, even though the...

The administration has maintained debilitating prices as well as exchange control measures, which fuel the black market, inflation, and shortages. In its quest to create a social system that is 21st century, the government has continued to implement in the form of ad-hoc and expensive nationalisation programs. The sum of billions of dollars could be removed from the nation through litigation to seize land and assets and an accumulation of outstanding contracts and bills have led to speculation that the state-owned company for oil, PDVSA, may fail to pay its interest on its loans. Critical shortages There is no sector that better reflects the goals, limitations...

It doesn't mean that men and women are equal, but rather that the desires, priorities, and needs of men and women must be considered when recognizing diversity among different groups. Although the world has made advancements toward gender equality through the United Nations' Millennium Development Goals gir, ls, women are still subject to violence and discrimination in many regions of the world. Consider the education of girls for instance, only 74 girls were in school for 100 boys in the year 1990 in the southern part of Asia. In 2012, enrollment levels that were the same. Girls are also faced with barriers to...
