“…Solar‐driven atmospheric water irrigation is an appealing way to liberate crop farming from long‐distance water and power supplies. [ 20 ] Here, we designed a simulated agriculture irrigation system containing a soft indium hydrogel to promote plant growth; the overall scheme for preparing the super hygroscopic hydrogel is shown in Figure a. To prepare the In hydrogel, InCl 3 was first dissolved in ethanol to get a seed solution.…”

The atmospheric water is ubiquitous and abundant, which could be effectively exploited for various applications. However, limited efforts devote to agriculture due to the slowly capture kinetics and highly dehydration temperature. Herein, benefit by a super hygroscopic hydrogel, we integrate a self‐sustainable atmospheric water irrigation system for plant growth at arid land. The hydrogel harvests water from the air during the nighttime, and efficiently releases adsorbed water when the system is exposed to sunlight. The water capture behavior by hydrogel is mainly relying on physisorption, multilayer moistures can be accumulated under weakly Van der Waals force. With the help of hydrophilic surface, the indium hydrogel has a maximum water uptake of up to 5.5 g g−1 at 90% RH. This hydrogel will induce a > 40°C surface temperature under AM 1.5G solar illumination, which is enough for water releasing, making the solar energy driven water‐recycling is possible. At last, the collected water quality meets the international drinking water standard, and then resulting a rapid growth of pea over 6 cm within 8 days.This article is protected by copyright.

“…Hunger and malnutrition are common cause of diseases, a decrease in people's working capacity and, as a result, inability to increase earnings and improve living conditions [16]. Goal 2 aims to end all forms of malnutrition, build sustainable food production systems [17], and adopt agricultural practices [18-20] that increase production, save ecosystems [21], strengthen the ability to adapt to climate change, extreme weather events, droughts, floods and other disasters and gradually improve the quality of land and soil [22][23][24][25].…”

The article is focused on determining the current situation in Russia on the way to achieving the goals of sustainable development in agriculture. When analyzing the literature, it was revealed that most of the goals and objectives of sustainable development are already, to a greater or lesser degree, incorporated into the main strategic and program documents in Russia. Achievements in the implementation of SDG 2 “End hunger, achieve food security and improved nutrition and promote sustainable agriculture” were considered. Statistical indicators of agriculture sustainable development in Russia are analyzed. The principles for development of the agrifood systems sustainability concept are formulated and presented. In the last century and a half, the main task of Russia in country’s food security has been to feed its population. At the present day, it can be stated that this problem has been mainly solved.

“…Autonomous machines are expected to be a game changer for open‐field arable crop farming (Gackstetter et al., 2023; Klerkx & Rose, 2020) which would facilitate more diverse, agroecological, and ecosystem services restoring farming practices (Daum, 2021; Pearson et al., 2022). Research suggests that within‐field heterogeneous, small‐scale, and spatiotemporal mixed cropping systems such as strip cropping (Ghaffarzadeh et al., 1994; Smith & Carter, 1998; Verdelli et al., 2012), pixel cropping (Ditzler & Driessen, 2022), patch cropping (Donat et al., 2022; Grahmann et al., 2021), and relay cropping (Patel, 2020; Tanveer et al., 2017) enable more diverse cropping practices.…”

Autonomous machines have the potential to maintain food production and agroecological farming resilience. However, autonomous complex mixed cropping is proving to be an engineering challenge because of differences in plant height and growth pattern. Strip cropping is technically the simplest mixed cropping system, but widespread use is constrained by higher labor requirements in conventional mechanized farms. Researchers have long hypothesized that autonomous machines (i.e., crop robots) might make strip cropping profitable, thereby allowing farmers to gain additional agroecological benefits. To examine this hypothesis, this study modeled ex‐ante scenarios for the Corn Belt of central Indiana, using the experience of the Hands Free Hectare‐Linear Programming (HFH‐LP) optimization model. Results show that per annum return to operator labor, management, and risk‐taking (ROLMRT) was $568/ha and $163/ha higher for the autonomous corn (Zea mays L.) and soybean [Glycine max (L.) Merr.] strip crop farm compared to the whole field sole crop and the conventional strip crop farms, respectively, that were operated by human drivers. The conventional strip cropping practice was found challenging as this cropping system required four times more temporary hired labor than autonomous strip cropping and three times more than whole field sole cropping. Even if autonomous machines need 100% human supervision, the ROLMRT was higher compared to whole field sole cropping. Profitable autonomous strip cropping could restore and improve in‐field biodiversity and ecosystem services through a sustainable techno‐economic and environmental approach that will address the demand for healthier food and promote environmental sustainability.
