| Abstract | There is currently an increasing societal and political shift towards more sustainable agricultural systems to provide both food production and ecological biodiversity levels. This shift has recently modified scientific questioning and brought up new research challenges for agro-ecological research. This is the case in particular for weed management, where issues have so far largely focused on the conflict between weeds and crop productivity. Here, we review recent findings that have led to a changing perception on weeds in agro-ecosystems and upcoming areas in terms of weed management options. Our main findings are that weeds have numerous interactions with other organisms and, in turn, some of these interactions can have direct, either negative or positive, effects on the functioning of the agro-ecosystem. Many interactions are species-specific, and therefore assessing the role of weed communities in the agro-ecosystem would benefit from further development in the functional grouping of weed species. In terms of weed management our review shows that alternative cropping systems can deliver both good levels of crop productivity and of weed management at the field level. Weeds respond to landscape attributes and there is a need to fully assess the scope for utilizing the spatio-temporal organization of cropping systems and uncultivated habitats as a tool for minimizing weed infestations. Weeds are also submitted to biological regulation through the predation of their seeds and further research is required to assess the effect of cropping systems and landscape on levels of weed natural enemies, and therefore on the potential contribution of biological regulation in the management of weeds. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
