Special Issue Information

Dear Colleagues,

In recent decades, the cultivation of agricultural products has been improved through more competitive management practices. Recent studies have shown that irrigation practices result in a remarkable increase in product quality and yield. In fact, traditional crop productions are being converted to intensive cultivation systems. Although this conversion is improving product quality and quantity and sector profitability, it requires a larger amount of energy input, which generates corresponding environmental impacts. Moreover, the agricultural phase uses the main quota of the total energy demand for the production of food, with irrigation as one of the main energy-demand activities.

The environmental impact of crop irrigation has been studied by several authors who found that achievement of sustainable food production included improvements in irrigation water use and pumping efficiency, where the energy inputs for irrigation were the major contributors to CO2 emissions.

The need to promote more sustainable agricultural production with respect to natural resources and human health is leading farmers and stakeholders to invest in renewable energy systems. Recently, several renewable energy technologies have been implemented in pressurized irrigation systems to reduce energy requirements while also reducing the related greenhouse gas emissions.

The aim of this Special Issue of Sustainability is to provide innovative experimental research, models, and tools focusing on renewable powered irrigation technologies, including the related economic and environmental impacts. This Special Issue may include but is not limited to:

  • Energy and environmental advantages of renewable powered irrigation systems;
  • Precision irrigation technologies;
  • Performances evaluation of renewable powered irrigation systems;
  • Mathematical modeling of on-farm irrigation energy requirements;
  • Solar-powered water pumping;
  • Economic assessments associated to renewable powered irrigation systems.

How Does the Control of Grain Purchase Price Affect the Sustainability of the National Grain Industry? One Empirical Study from China
Sustainability 2020, 12(5), 2102; https://doi.org/10.3390/su12052102 - 09 Mar 2020

As one of the most important grain protection policies in China, the minimum purchase price policy prevents the fluctuation of grain output and protects the interests of farmers by regulating the prices of major grain varieties. For developing countries with a shortage of agricultural resources, represented by China, an in-depth study on the implementation effect and public satisfaction of this policy is of great significance for promoting the sustainable development of the grain industry. Based on the interest demands of the government, farmers, grain enterprises and consumers, this paper constructs a policy satisfaction evaluation model based on the Analytic Hierarchy Process and Fuzzy Comprehensive Evaluation. The research shows that the implementation effect of this policy has promoted the sustainable development of China’s grain in four aspects: improving farmers’ enthusiasm for planting, optimizing the structure of supply and demand, reducing the adverse impact of disasters, and ensuring the steady increase of output. However, due to the differences in natural resources and folk customs, the implementation effect of this policy varies in different regions. Full article

Sustainable Intensification? Increased Production Diminishes Omega-3 Content of Sheep Milk
Sustainability 2020, 12(3), 1228; https://doi.org/10.3390/su12031228 - 08 Feb 2020

Intensifying agricultural production alters food composition, but this is often ignored when assessing system sustainability. However, this could compromise consumer health and influence the concept of “sustainable diets”. Here, we consider the milk composition of Mediterranean dairy sheep, finding inferior fatty acid (FA) profiles with respect to consumer health as a result of a more intensive system of production. Semi-intensive management produced 57% more milk per ewe, with a 20% lower fat content (but inferior fat composition). The milk had a nutritionally poorer fatty acid (FA) profile, with an 18% lower omega-3 FA concentration (n-3) (19% fewer long-chain n-3s) and a 7% lower monounsaturated FA concentration but a 3% higher saturated FA (9% higher in C14:0) concentration compared to ewes under traditional, extensive management. A redundancy analysis identified close associations between fat composition and animal diets—particularly concentrate supplementation and cultivated pasture grazing—and n-3 was associated with grazing in diverse, native mountain pastures. This paper questions if identifying such key elements in traditional systems could be deployed for “sustainable intensification” to maintain food quality while increasing output. Full article
