Due to researches of the International Food Policy Research Institute (IFPRI) and the World Resources Institute (WRI), the soil degradation of the latest twenty years has significantly reduced the crop productivity, and that is especially vitally critical for poor and heavily populated countries.
Although agroecosystems groups, like EMAP, Agricultural Research Service, National Agricultural Statistics Service, and Soil Conservation Service in the USA for instance, perform agroecosystems monitoring, trying to collect data through surveys of growers; this rue is hardly applicable to the most of the countries left. If it were so and the governments of other countries paid enough attention to gathering field samples of cropland to include annual crops, pastures, woody perennial crops, adjacent natural areas, and farm ponds, it would definitely result in a positive ecological impact as regards to agroecosystems.
Agroecosystems, being the first comprehensive audit of the world agriculture's ability to provide sufficient food, goods and services, is vital for sustaining a human life. Regretfully, no modern techs can help the whole world today as the situation has grown bad for years ago and it is dramatically irrevocable to think of turning back those precious times of Eden's gardens. Still, the chances to recover the Earth agroecosystems at least partially exist. The other topic for discussion is whether the ways of resurrecting people quickly will take its smooth way in regards to human needs. Our perfect world is created so that being left untouched for several years, it would restore itself for seventy percent. The last thing, however, is impossible to take place ever due to the growing need and greed of the human nature.
Only several more factors need to be added here: agroecosystems lack clear water, air and soil. So simple and so hard to realize that agriculture consumes seventy percent of the freshwater withdrawn annually by humans. The irrigation is draining more water than is being replenished by rainfall, causing water tables to fall. What is more, we have pollution of water resources by an excessive use of fertilizers and pesticides, omitting the work of factories, plants and cars all around us. Growing of the population will never abolish those measures of modern human life.
We can conclude sadly that the food production of the whole world seems to be at risk today as far as farming methods of modern agriculture lead to the soil degradation, parched aquifers, polluted waters, and cause the loss of animal and plant species. All of the factors enumerated are serious cases to pay special attention to. Despite the hardworking process of agroecosystems' defenders, the situation will hardly show the signs of productive decisions what concerns the regeneration of the biggest part of agroecosystems as a whole. Minding the fact of the Sahara desert, extending for approximately ten miles a year, you can only substitute Africa with any other place on Earth to see the destructive fruits of the human activity.
