The Uttara Kannada district of Karnataka well known as the “Pepper Queen” during colonial times gradually declined in stature and came to be known as a backward, forest district in need of “development.” These concerns framed the post-independence debates on the development of the district in terms of forestry programs and hydroelectric power projects, to help in the growth story of India. In the post-liberalization period, we have observed increasing market- and state-led drives of “resource development and conservation.” In recent years, international recognitions have come to the region’s sustainable agricultural practices and to its rich biodiversity, and it is declared a Heritage site. The dominant agricultural community of the region, the Havyaks, known for their environmentally sustainable spice garden farming, are credited with spearheading environmental movements against the material practices of the state. This article attempts to understand the complex social ecology of the region and the multiple ways in which it is portrayed and the way people talk about it. It attempts to juxtapose the environmental narrative along with the development narrative of the district and to understand and map the complex ground realities that exist interlinking the local with the global.

Using a composite environmental index, we assessed how environmentally sustainable agriculture is by examining water bodies of groundwater (WBG) in Slovenia. Apart from studying identifiable differences among 21 WBG, we also analysed and detailed the pressures of agricultural activities including by different types of aquifer porosity. We found that the most heavily burdened WBG have an intergranular type of porosity. From the standpoint of environmental sustainability agriculture is ill-suited on all five of the alluvial plains with intergranular aquifers in Slovenia. The lowest index was calculated in the area of the WBG in the Drava basin (-0.54), followed by the Mura (-0.34) and Sava basin together with the Ljubljana Marshes (-0.24). In order to better illustrate responsiveness, through analysis of spatial patterns of ecologically cultivated areas, we evaluated the distribution of the most sustainable agricultural practices and found that organic farming is more prevalent on water bodies with predominantly karst type of porosity (17.1% of organically cultivated agricultural land) and it occurs least on alluvial plains with intergranular aquifers (barely 3.7% of organically cultivated agricultural land). Calculations of the sustainability index of agriculture at the level of WBG proved to be very suitable approach for determining environmental sustainability.

Fragaria × ananassa is a fruit grown all over the world, appreciated for its organoleptic and nutraceutical properties. Together with other berry fruits, it is rich in bioactive molecules that make it a beneficial fruit for human health. However, strawberry cultivation is influenced by pre- and post-harvest factors. Being a small plant, its fruit comes into direct contact with the soil and, as such, can quickly decompose. To reduce this inconvenience, farmers have used different strategies to mulch the soil, and the most useful method is polyethylene mulch films that are not biodegradable. The focus on environmentally sustainable agriculture can be represented by a transition to biodegradable mulch films. In our study, ten biodegradable mulch films were used to understand their effectiveness in covering the soil during the cultivation cycle of strawberry cv. Rociera. Polyethylene film was considered the control. The best yield and the highest number of fruits with greatest size and quality were obtained on polyethylene, BioFlex® (P2), Bio 6, and Bio 7 films. On BioFlex® (P2) and Bio 3 biodegradable films, strawberries showed a higher calcium and magnesium content, respectively. These results may encourage growers toward the use of eco-sustainable agricultural practices, such as biodegradable mulch films.

The highest yield (420 kg/ha) was recorded in the year 2011-12. In Front-Line Demonstration, it was 27.27 percent more over the farmers practice (320 kg/ha), however, the lowest yield (350 kg/ha) was recorded in the year 2010-11 under Front-Line Demonstration and 310 kg/ha in farmers' practice. Increase in the yield (27.27%) under Front-Line Demonstration over farmers practice was obtained during the year 2011-12. The variation in the percent increase in the yield was found due to variation in agro climate parameter under rainfed condition. Under sustainable agricultural practices, with this study it is concluded that the Front- LineDemonstration programme was effective in changing attitude, skill and knowledge of improved / recommended practices of High Yielding Varieties of peas included adoption. This also improved the relationship between farmers and scientist and built confidence between them.

Krishi Vigyan Kendra laid down Front Line Demonstration in the year 2010-11 and 2011-12 introducing new, high yielding and scented variety “Pusa Sugandha-3” and applying scientific practices in their cultivation. The FLDs were carried out in village “Dainiha” of Sidhi district in supervision of KVK scientist. The productivity and economic returns of paddy in improved technologies were calculated and compared with the corresponding farmer's practices (local check). Improved practices recorded higher yield as compared to farmer's practices. The improved technology recorded higher yield of 30.83 q/ha and 32.65 q/ha in the year 2010-11 and 2011-12, respectively than 22.13 and 24.21 q/ha. The average yield increase was observed 37.15 per cent. In spite of increase in yield of paddy, technology gap, extension gap and technology index existed. The improved technology gave higher gross return (37020 and 39180 Rs./ha), net return (16820 and 18920 Rs./ha) with higher benefit cost ratio (1.83 and 1.93) as compared to farmer's practices. The variation in per cent increase in the yield was found due to the poor management practices, lack of knowledge and poor socio economic condition. Under sustainable agricultural practices, with this study it is concluded that the FLDs programmes were effective in changing attitude, skill and knowledge of improved package and practices of HYV of paddy adoption.

AbstractWastewater treatment plants produce hundreds of million tons of sewage sludge every year all over the world. Vermicomposting is well established worldwide and has been successful at processing sewage sludge, which can contribute to alleviate the severe environmental problems caused by its disposal. Here, we utilized 16S and ITS rRNA high-throughput sequencing to characterize bacterial and fungal community composition and structure during the gut- and cast-associated processes (GAP and CAP, respectively) of vermicomposting of sewage sludge. Bacterial and fungal communities of earthworm casts were mainly composed of microbial taxa not found in the sewage sludge; thus most of the bacterial (96%) and fungal (91%) taxa in the sewage sludge were eliminated during vermicomposting, mainly through the GAP. Upon completion of GAP and during CAP, modified microbial communities undergo a succession process leading to more diverse microbiotas than those found in sewage sludge. Consequently, bacterial and fungal community composition changed significantly during vermicomposting. Vermicomposting of sewage resulted in a stable and rich microbial community with potential biostimulant properties that may aid plant growth. Our results support the use of vermicompost derived from sewage sludge for sustainable agricultural practices, if heavy metals or other pollutants are under legislation limits or adequately treated.

Nanobiotechnology in agriculture is a driver for modern-day smart, efficient agricultural practices. Nanoparticles have been shown to stimulate plant growth and disease resistance. The goal of sustainable farming can be accomplished by developing and sustainably exploiting the fruits of nanobiotechnology to balance the advantages nanotechnology provides in tackling environmental challenges. This review aims to advance our understanding of nanobiotechnology in relevant areas, encourage interactions within the research community for broader application, and benefit society through innovation to realize sustainable agricultural practices. This review critically evaluates what is and is not known in the domain of nano-enabled agriculture. It provides a holistic view of the role of nanobiotechnology in multiple facets of agriculture, from the synthesis of nanoparticles to controlled and targeted delivery, uptake, translocation, recognition, interaction with plant cells, and the toxicity potential of nanoparticle complexes when presented to plant cells.
