Food security is a global challenge that aligns with several Sustainable Development Goals (SDGs), including SDG 1 - “No Poverty”, SDG 2 - “Zero Hunger,” SDG 3 - “Good Health and Well-being,” SDG 13 - “Climate Action,” and SDG 15 - “Life on Land.”. To effectively address this issue, a convergence of agriculture and technology is crucial, incorporating precision agriculture, sustainable agriculture, bio-economy and advanced technologies such as machineries, Artificial intelligence-meachine learning&nbsp;and geospatial technology. Recent trends in food security worldwide have witnessed the adoption of technological advancements. However, it is important to consider biodiversity when implementing and adopting technological advancements. The integration of technology in agricultural practices aim to reduce chemical usage&nbsp;in farms, while increased production remains the main objective of smart farming and Precision Agriculture. By minimizing the use or implementing localized approaches for chemicals on farms, we can preserve soil-faunal diversity, which is at risk along with targets due to excessive applications of pesticides, herbicides, and insecticides. Geospatial technology plays a significant role by leveraging remotely sensed images acquired through satellites, aerial platforms, and GPS-tagged drones to enhance agricultural practices, improve crop growth and increase crop yields. Through geospatial technology, we can map and monitor soil and crop conditions, and effectively conserve, protect, and manage biodiversity on a global scale. The applications of remote sensing technology consider ecological and environmental parameters, soil factors, crop conditions, and plant-soil diversity to optimize yields and agricultural productivity. Additionally, the evaluation of various agricultural practices such as sustainable agriculture, bio-economy, using technology can contribute to increased yields, profitability, and biodiversity conservation as central components of these practices. This study emphasizes that achieving the SDG objectives is attainable through agriculture, which has direct and indirect connections to all SDGs. Geospatial technology plays a vital role in supporting the objectives at spatial and temporal scales by facilitating agricultural practices, ensuring&nbsp;food security, preserving biodiversity, monitoring soil and crop conditions, and promoting sustainable development.

Highlighting the role of agriculture and geospatial technology in food security and sustainable development goals

The present study is taken up to record variations in the extent of area of two polygons–(i)a ground measured area of a university campus, (ii)enclosing the Ganga basin and a polygon covering (iii)India to examine the changes in both shape and area–under different map projections with various parameters. The exercise brought forth interesting results. Depending on final ranks worked out based on minimum differences in extent of areas and shape distortion in the case of India, it is suggested to adopt either (i) LCC projection with Everest India-Nepal datum, First Standard Parallel (FSP) 24.50, Second Standard Parallel (SSP) 28.50, Latitude of Origin (LO) 16.253259, Central Meridian (CM) 80.8749 or (ii) LCC projection with WGS 84 datum, FSP 24.50, SSP 28.50, LO 16.253259, CM 80.8749 or (iii) Polyconic with Everest India-Nepal datum, CM 84.50, LO 13.00, for mapping both smaller areas on larger scales and larger areas on smaller scales.

The design of amino acid sensors have significant applications in biomarkers. Herein, we have developed an achiral Fe(III)-complex [FeIIIL(bzac)] (complex 1) (H2L = N,N′-dimethyl-N,N′-bi(2-hydroxy-3,5-dichlorobenzyl)-ethylenediamine (H2L) that shows highly selective sensing of histidine over others in an aqueous methanolic solution. The complex has been synthesized by a simple stirring method using H2L and benzylacetone (bzac) as the ancillary ligand and characterized by single crystal X-ray diffraction analysis along with other spectroscopic studies. Structural study shows that it is a simple mononuclear complex though the single molecule is chiral; however, the overall crystalline lattice is achiral in nature. In the complex, Fe(III) shows distorted octahedral geometry, and each discrete complex is connected by supramolecular hydrogen bonding interactions to form achiral 3D supramolecular structure. Both the absorption spectral analyses reveal that the complex has peaks at 484 nm due to ligand-to-metal charge transfer (LMCT) and emission spectra have a peak at 566 nm. In the presence of histidine, there is a red-shift of about 70 nm and peaks arise at about 564 nm, while the emission spectra shows that the peak at 566 nm disappears completely and a new peak at 603 nm appears. In the presence of other amino acids, there is no such distinct change in both the absorption and emission spectra of the complex. It also acts as an effective catalyst toward the oxidation of 3,5-di-tert-butylcatechol in methanol solvent.
