因此,有一个问题是如何满足农田的需要,这将需要满足有机农业的需要。即使土地是可用的,还有许多其他的要求,如需要较小的动物,有大量农场动物的要求将很难实现。诺贝尔奖获得者Normany Borlaug在2002年的一次会议上说,世界上不可能养活60亿人(Leifeld et al., 2013)。为了达到同样的目的,世界上大部分的森林将需要被砍伐,大部分的土地只能在很短的时间内生产。约翰·埃姆斯利(John Emsley)指出,为全世界争取有机农业的努力将导致约20亿人死亡,这可能是人类有史以来面临的最大灾难(Andersen et al., 2015)。

近年来,有机农业及其发展带来了新的吸引力。许多研究也发现,与其他传统作物相比,通过有机方法种植的作物产量更高。(Strandberg等,2013)。从研究中发现,在最初的几年里,有机作物的产量将会很低。这是因为土壤和周围的生物多样性将不得不从以前在农场使用的化学物质中恢复。为了改进这种方法,需要几个季节。

尽管如此,另一个与之相反的观点是,即使有机农场将提供他们的全部产量,他们将只能养活世界总人口的三分之一或一半。但后来人们发现,这种观察是由于缺乏适当的数据而进行的。

瑞士有机农业研究所的科学家最近进行的一项研究表明,有机农场的产量仅比传统农场低20%。在北美和欧洲进行的200多个不同的研究发现,有机产量可以达到总产量的80%左右(Lapple et al., 2013)。此外,许多研究是通过“154个生长季节”对美国通过raid灌溉有机种植作物的农场进行的。研究发现,这些农场的有机玉米产量约为常规产量的94%,有机小麦产量约为97%。另一方面,有机番茄的生长速度几乎相同。

Thus, there is a question to how to fulfil the needs of the farmlands which would be required to fulfil the needs of the organic farming. Even if the land is available, there are many other requirements such as the need for lesser animals, the requirement to have large number of farm animals would be tough to be fulfilled. Nobel Normany Borlaug stated in a conference in 2002 that it will not be possible to feed 6 billion people in the world (Leifeld et al., 2013). In order to try for the same, the most of the forests in the world would be required to be cut down and most of the lands will be productive only for a very short time period. John Emsley states that trying for the organic farming for the entire world would perish around 2 billion people which can be the greatest catastrophe faced by the humans ever (Andersen et al., 2015).

In the recent times, there has been an added attraction related to the organic farming and its growth. Many studies have also found that the crops which are grown through the organic processes have a high yield in comparison to other traditional crops. (Strandberg et al., 2013). From the studies, it has been found that in the initial few years, there will be a low production of organic crops. This is because the soil and the surrounding biodiversity will have to recover from the chemicals which had been previously used in the farms. In order to refine this approach, several seasons will be required.

Though, another counter argument in the same is that even if the organic farms will be giving their full yield, they will be able to feed only one third or half of the overall population of the world. But later, it was found that this observation has been done due to the lack of the proper data.

A recent study which has been conducted by the scientists in the Research Institute for Organic Agriculture in Switzerland had stated that the organic farms are only 20 percent lesser productive in comparison to the conventional farms. As per more than 200 different studies which have been conducted in North America and Europe, it has been found that the organic yields can be around 80 percent of the overall yields (Läpple et al., 2013). Further, many studies were done by “154 growing seasons” on the farms in which the crops were grown organically through the process of raid fed irrigation in United States. It was found that these farms have organic yield of corn to be around 94 % of the conventional yield and yield of organic wheat to be around 97 per cent. On the other hand, the growth rate of organic tomatoes was almost the same.
