TL;DR: A large number of patents deal with the production of fertilizers from animal manure, plant sources and other organic wastes, which are more sustainable that the chemical fertilizers that are being currently used.
Abstract: The paper discusses the patents that have been filed in the areas of sustainable development in agriculture, food and nutrition and use of natural resources in achieving this goal. A large number of patents deal with the production of fertilizers from animal manure, plant sources and other organic wastes, which are more sustainable that the chemical fertilizers that are being currently used. Sustainability in agriculture is achieved in developing processes for the manufacture of biopesticides/insecticides and bioactive agricultural products. Development of novel sustainable agricultural processes has also been the focus of researchers and technologists. Plant derived nutritious food products are sustainable and can cater for the growing population burden. This has been the focus of several patents. Processes for enhancing the nutrition in food also serve the purpose of catering for the under nourished population.

TL;DR: In this article, the potential of agricultural residues as raw materials for the production of bioactive products considering their availability, processing, and their chemical and biological properties is discussed, and new data on the potential as biopesticides of some selected crop-and processing-based residues are provided.
Abstract: Agricultural industry produces billions of tons of residues in non-edible portions derived from the cultivation and processing of a particular crop. These residues can cause pollution, management and economic problems worldwide. This is the reason for the development of different strategies to use agricultural and industrial residues as a source of high value-added products. This review gives an overview of the potential of agricultural residues as raw materials for the production of bioactive products considering their availability, processing, and their chemical and biological properties. We also provide new data on the potential as biopesticides of some selected crop- and processing-based residues.

TL;DR: New technologies have significantly improved the speed with which natural products can be discovered and evaluated for biological activities, and combinatorial chemistry combined with chemical diversity theory and high throughput screening allows for swifter production and testing of synthetic compounds.
Abstract: Biopesticides offer a more sustainable solution to pest control than synthetic alternatives. As chemical pesticides are withdrawn owing to resistance problems or because they are no longer commercially viable, an opportunity arises for biorational solutions. Biopesticides do not feature residue problems which are a matter of significant concern for consumers. However, biopesticides are not as effective as chemicals. Compatibility with synthetic pesticides varies and shelf life is often shorter. Considering the growing demand for organic production of food and registration-related problems, the number of pest management products that can be used in this sort of production is limited. Natural product-based search strategies have had some notable successes. The pesticide industry’s natural product search efforts to date have concentrated on compounds of microbial origin primarily from non-pathogenic soil microbes. Less effort has been put into the search for pesticides of plant origin. Bioassay-directed isolation has been the preferred search method once a producing organism has been selected. This laborious approach often leads to the rediscovery of known compounds. Modern tandem separation/chemical characterization instrumentation can eliminate much of this problem by identifying compounds before they are bioassayed. Pesticide search strategies discovery are no different from drug research. The dominant and most successful strategy has been that of systematically screening large numbers of synthetic compounds followed by the structure optimization of lead compounds. The biorational approach entailing the design of inhibitors of specific molecular target sites was in vogue for several years. Using natural products as pesticides or as leads for new ones has had intermediate success. New tools have supported each of these strategies. For example, combinatorial chemistry combined with chemical diversity theory and high throughput screening allows for swifter production and testing of synthetic compounds. Similarly, new technologies have significantly improved the speed with which natural products can be discovered and evaluated for biological activities.
