The impact of population pressure on global fertiliser use intensity, 1970–2011: An analysis of policy-induced mediation

On the Use of Multivariate Analysis and Land Evaluation for Potential Agricultural Development of the Northwestern Coast of Egypt

“…The world's population will increase to reach approximately 9.7 billion by 2050 [1,2]. The huge population increase will impact agricultural resources as it causes global food security pressure on the lack of agricultural lands [3,4]. Two types of challenges put pressure on governments, namely the increasing population on the one hand, and the decrease in productive land on the other hand [5].…”

“…Two types of challenges put pressure on governments, namely the increasing population on the one hand, and the decrease in productive land on the other hand [5]. There are two ways that governments can counteract overpopulation: the first is to encourage farmers to increase crop yields by using land fertilizers, pesticides, etc., which affect environmental quality, and the second is to rely on imports to fill the food gap [3,5]. Therefore, it is required to increase the efforts to improve living standards to provide safe food to feed citizens [6,7].…”

Factor allocation structure and green-biased technological progress in Chinese agriculture

“…From 1978 to 2016, China's total fertiliser-using increased by nearly six times (Wang et al, 2019), accounting for more than 1/3 usage of global fertiliser, but the utilisation rate was less than half of the world average (Wu et al, 2018), and longterm excessive use of agrochemicals has caused inestimable damage to environmental quality, agroecology, food security and human health (Savcı, 2012;Wang et al, 2019;Wu et al, 2018;Xiang et al, 2020). While it is possible to break the growth bottleneck of relying solely on increased factor inputs by increasing total factor productivity, such technological advances, with the primary objective of maximising agricultural output, still need to be applied to the agricultural production chain through specific factors of production, such as fertiliser and pesticide, which can have a negative impact on the ecosystem.…”

“…Particularly under China's current household registration system, rural labourers entering urban employment still maintain arable soil and work part-time in agricultural production activities, which makes it difficult to transfer and concentrate soil and limits the substitution of machinery for labour (Ito, 2010;Li et al, 2017). In order to maintain food production, farmers often tend to add more fertiliser per unit area of soil to make up for the lack of labour input (Liu et al, 2014;Wang et al, 2019), which further induces agricultural technology progress towards the fertiliser-using, aggravating agricultural non-point source pollution (Xiang et al, 2020). At the same time, however, scholars have found that there is a negative correlation between land and fertiliser, with a significant 0.5% reduction in fertiliser and pesticide use for every 1% expansion of land area (Wu et al, 2018).…”

Effect of organic and chemical fertilization on the onion crop (Allium cepa L.)

“…Due to the risks that the indiscriminate use of agrochemicals represents for human health (Cabral-Pinto et al, 2019) and the environment (Olanipekun et al, 2019;Xiang et al, 2020), some modern agricultural techniques have been questioned and there is an increasing interest in reducing its negative effects. To achieve this objective, it is necessary to resort to agricultural production methods focusing on the efficient use of resources which are conducive to sustainable agriculture.…”
