Feeding the World Sustainably: Agroecology vs. Industrial Agriculture

Feeding the World Sustainably: Agroecology vs. Industrial Agriculture | population geography | Scoop.it
There are currently 1 billion people in the world today who are hungry. There's also another billion people who over eat unhealthy foods.

 Food production around the world today is mostly done through industrial agriculture, and by judging current issues with obesity, worldwide food shortages, and the destruction of soil, it may not be the best process. We need to be able to feed our world without destroying it, and finding a more sustainable approach to accomplishing that is becoming more important.

The current system contributes to 1/3 of global emissions, is a polluter of our world’s water resources, and is a contributor to health problems. Industrial agriculture relies on mass produced, mechanized labor-saving policies that have pushed people out of rural areas and into cities, consolidating land and resources into fewer hands.

Agroecology looks to reduces agriculture’s impact on climate by working within natural systems. This is especially beneficial in rural areas, because the local community a major part of the growing process. The approach can conserve and protect soil and water — through terracing, contour farming, intercropping, and agroforestry — especially beneficial in areas where farmers lack modern irrigation infrastructure, or have farms situated on hillsides and other difficult farming sites...

Clearly industrial agriculture is not sustainable, and must be replaced entirely with systems that reverse the current damage and restore the balance that used to exist before we messed things up.  We can use plants and animals not only to feed ourselves, but to *improve* the environment for all life on the planet.

Jared Diamond: Why societies collapse

This talk (based on his controversial book, Collapse) explores the economic and environmental causes behind why a society that is overextended might collapse or recede from a golden age. Jared Diamond uses multiple historical examples such as classical Mayan civilization and Easter Island as well as modern societies such as Rwanda and Haiti, to argue that unsustainable management of the environmental resources might lead to short-term economic successes, but the environmental degradation may threaten the long-term economic viability of the economic system. This talk ties agricultural patterns, economic practices and political policies that can strengthen or weaken a society and the book looks to the past to assess the challenges of the present and future. This TED talk brings geographic concepts and spatial thinking to many of contemporary global issues.

Feeding 7 billion & our Fragile Environment

Feeding 7 billion & our Fragile Environment | population geography | Scoop.it

This photoessay puts together a diverse set of issues that are interconnected.  Industrial agriculture and metropolitan pollution; rising energy prices to sustain consumptive lifestyles with environmental degradation linked to oil spills; regions susceptible to climate change and regions producing that change...thought-provoking.

I had always known that the amount of humans on this planet was way too much, but i had never realized that our daily consumption of all these resources can result in the issues that are shown in these pictures. These pictures show areas that are highly polluted and it is overwhelming to think that the beautiful earth that we live in is filled with images like that. The number of factors that affect our environment is countless, especially with the growing figures of pollution, waste, use of natural resources and food production. The photo that stood out to me the most from this collection, is the one where the polar bear had to resort to eating a polar bear cub. It is difficult to think that the polar bear did that act as a sign of desperation because of the lack of food affected by the changing environment.
