“…Therefore by adopting alternative sustainable agriculture practices the diversity of paddy ecosystem can be protected (Chappell & Lavalle 2011). The number of weed species recorded from Bhadrak district is comparable with other regions of Asia [191 species in Japan (Kasahara 1959),136 species in Sri Lanka (Chandrasena 1988), 96 species in Thailand (Tomita et al 2003a,b), 145 species in Tamil Nadu, India (Dhanam & Elayaraj 2014), 82 species in Nepal (Nowak et al 2016), 113 species in Vietnam and the Philippines (Fried et al 2017), 272 species in China (Yun-he & Sheng 2014)]. The highest contribution of family Poaceae is in accordance with Turki & Sheded (2002) and Hakim et al (2013).…”

The weed flora associated with field crop of rice in Bhadrak district of Odisha, India is studied for a period of 2 years (June 2016 to May 2018) based on data obtained from field exploration and literature consultations. Data are collected using standard procedures. The weed association is comprised of 149 species related to 41 angiosperm families and one pteridophytic family. Angiosperms are distributed in 8 superorders and 19 orders. 36.5% of the species are recorded from the superorder Commelinids, 18.9% from Malvids, 14.9% from Lamids, 13.5% from Fabids and 10.1% from Companulids as per APG III classification. Order Poales (48), Gentianales and Asterales ( 14) each, Caryophyllales (13) and Fabales ( 11) accounts for about 67.6% of the species in the district. The predominant families are Poaceae and Cyperaceae. The dominant species are Ammannia baccifera, Alternanthera sessilis, Argemone mexicana, Croton sparsiflorus, Cyperus alopecuroides, Echinochloa crusgalli, Eleocharis dulcis, Fimbristylis miliacea, Hygrophila auriculata, Ludwigia hyssopifolia and Oryza rufipogon. Forty eight of the identified species are perennial and 101 annual species. The therophytes are represented by 45.6% of the life form spectrum. Habitat wise distribution analysis shows forbs share 88 species followed by grasses (29 species) and sedges (18 species) respectively. Of the reported species 37.6% are used for animal fodder, 29.5% for the treatment of various diseases and 7.4% for edible purposes. Considering the importance of weed flora in the rice fields, this research will hopefully improve the monitoring and management of weed flora in the study area and highlight their importance in maintaining ecosystem services which could be a valuable tool for its conservation, preservation and addition of the local biodiversity.

“…Differences in plant species numbers and composition have been found particularly between lowland and upland areas (Fried et al 2017), and there is evidence that traditional multiple and intercropping systems should be promoted to support high plant diversity levels in smallholder landscapes . LEGATO contributes to a better understanding of the variation in plant composition through a series of study sites in Vietnam and the Philippines, at different altitudes, and with different human impact on fields and surrounding structures.…”

“…LEGATO contributes to a better understanding of the variation in plant composition through a series of study sites in Vietnam and the Philippines, at different altitudes, and with different human impact on fields and surrounding structures. The focus of the research is at field and landscape scale, and the land use intensity has been found to be much reflected by the weed diversity (Fried et al 2017).…”

In a cross-disciplinary project (LEGATO) combining inter-and transdisciplinary methods, we quantify the dependency of rice-dominated socio-ecological systems on ecosystem functions (ESF) and the ecosystem services (ESS) the integrated system provides. In the collaboration of a large team including geo-and bioscientists, economists, political and cultural scientists, the mutual influences of the biological, climate and soil conditions of the agricultural area and its surrounding natural landscape have been analysed. One focus was on sociocultural and economic backgrounds, another on local as well as regional land use intensity and biodiversity, and the potential impacts of future climate and land use change. LEGATO analysed characteristic elements of three service strands defined by the Millennium Ecosystem Assessment (MA): (a) provisioning services: nutrient cycling and crop production; (b) regulating services: biocontrol and pollination; and (c) cultural services: cultural identity and aesthetics. However, in line with much of the current ESS literature, what the MA called supporting services is treated as ESF within LEGATO. As a core output, LEGATO developed generally applicable principles of ecological engineering (EE), suitable for application in the context of future climate and land use change. EE is an emerging discipline, concerned with the design, monitoring and construction of ecosystems and aims at developing strategies to optimise ecosystem services through exploiting natural regulation mechanisms instead of suppressing them. Along these lines LEGATO also aims to create the knowledge base for decision-making for sustainable land management and livelihoods, including the provision of the corresponding governance and management strategies, technologies and system solutions.
