Soy Cultivation in South America
The expansion of soy bean Soy cultivation has shown an increasing expansion throughout Argentina, Brazil, Bolivia and Paraguay, in the last decade. This remarkable increase is explained by its economical importance in the region, and as a consequence, it is difficult to regulate its progress and attenuate its potential socio-environmental impacts. In 2012, in these 4 countries the area ...

Insecticide risk map exposes threat to aquatic life
The global threat that insecticides pose for aquatic biodiversity has been revealed in a recent modelling study that pinpoints areas at greatest risk. The mapping exercise conducted by the researchers reveals that aquatic life in water bodies within 40 per cent of the global land surface is at risk from insecticides running off the land. Published in Environmental Pollution last month (30 ...

Influence of marketing mix elements on the intention of sugarcane farmers in Thailand to use commercial tailor–made fertiliser
Tailor–made fertiliser (TMF) is a new practice in Thailand that aims to achieve a more efficient use of a fertiliser on cultivated soil. This study attempts to determine farmers' attitudes toward a marketing mix of TMF and to investigate factors influencing the farmers' intention to use TMF in accordance with the marketing mix strategy. A survey was conducted among 387 sugar cane farmers who were ...

Seeds of change in sub-Saharan Africa
In the late 1900s, as per-acre grain yields moved to 3 metric tons per hectare in South and Southeast Asia and Latin America, 5 metric tons per hectare in China, and 10 metric tons per hectare in North America, Europe and Japan, there’s one place where production stagnated big time: sub-Saharan Africa, where loss of soil fertility on small farms trapped grain production at an unsustainable ...

Monitoring greenhouse gases from biofuel crops - Case study
Global issues such as climate change and energy security have driven rapid growth in renewable energy production – wind, solar, tidal, geothermal, hydro, biofuels etc. However, logically, each of these methods should deliver a net benefit in terms of greenhouse gas (GHG) reduction, so researchers in the United States have employed portable FTIR analysers to study the GHG emissions of ...

What is the Future of Horticultural Science in Africa?
Horticulture is a labour intensive sector that is important for human wellbeing: 'agriculture supplies protein, carbohydrates and staple crops - but we would have a pretty boring life without horticulture.' Nevertheless, in many countries, faculties of agriculture and their departments of horticulture have been swallowed by schools of life or earth sciences. As a result horticulture gets ...

Climate, vulnerability and farming: a preliminary study among Australian food growers
The present study examines climate change, vulnerability to climate, and other environmental challenges from the perspective of 80 horticulture operators from different Australian states. Vulnerability in the form of storms and droughts are respondents’ main environmental concerns; in some cases, the impact of wildlife displacement is affecting their production outputs. In addition, substantial ...

Environmental sustainability, sustainable livelihood and poverty reduction: the case for tribal agricultural technology
Environmental degradation is very closely associated with economic growth, which leads to the popular concept of sustainable development. The idea of sustainable development also has a component of damage to the environment, though it is minimum. However, there is one thing that has the potential of promoting development along with poverty reduction with the true spirit of the idea of ...

The orbit of commodified technoscience: innovations in agricultural technology in India
The paper reviews the strategies by the Government of India over time to improve the state of agriculture. The institutional framework within which these strategies were conceived of and implemented though have contributed to improvement in agricultural productivity have led to larger consequences. Productivity based on green revolution strategy has reached a plateau and substantial yield gaps ...

The cloud isn`t just for rain anymore
Precision agriculture has been a key enabling technology to achieve higher yields with lower cost and less environmental impact, while keeping the cost of food fairly stable Has global agricultural productivity increased or decreased in the last 25 years? It has, in fact, more than doubled since 1985. Next to advances in seed genetics, precision agriculture has been a key enabling technology to ...

Chemical and ecological control methods for Epitrix spp.
Very little information exists in regards to the control options available for potato flea beetles, Epitrix spp. This short review covers both chemical and ecological options currently available for control of Epitrix spp. Synthetic pyrethroids are the weapon of choice for the beetles. However, the impetus in integrated pest management is to do timely (early-season) applications with something ...

Social life cycle assessment and participatory approaches: A methodological proposal applied to citrus farming in Southern Italy
Recently, Social Life Cycle Assessment (S‐LCA) has been developed under the methodological framework of Life Cycle Thinking (LCT) in order to evaluate the social impacts that emerge during the overall life cycle of a product or service. There is not yet a standardised methodology for S‐LCA as there is for environmental LCA (eLCA), because the social impacts S‐LCA is concerned with not only ...

Effects of pyrethroid insecticides in urban runoff on chinook salmon, steelhead trout, and their invertebrate prey
Pyrethroid insecticides can affect salmonids either indirectly through toxicity to their prey or directly by toxicity to the fish themselves. In support of a study on pyrethroid impacts to Chinook salmon and steelhead trout in the American River (Sacramento, California), 96‐h EC50 and LC50 values for the pyrethroid bifenthrin were determined for taxa not traditionally used for toxicity testing ...

Case study - Neutralization basin odor control for agricultural chemical production
Challenge: An agricultural plant located in the Midwest manufactures herbicides, pesticides, fungicides, and insecticides. Strict environmental regulations require the company to capture and neutralize all surface runoff and grey water produced at the plant before disposing into the municipal system. In addition, air permits prohibit any odors to cross their fence lines. As the water collects ...

Environmental fate of emamectin benzoate after tree micro injection of horse chestnut trees
Emamectin benzoate, an insecticide derived from the avermectin family of natural products, has a unique translocation behavior in trees when applied by tree micro injection (TMI), which can result in protection from insect pests (foliar and borers) for several years. Active ingredient imported into leaves was measured at the end of season in the fallen leaves of treated horse chestnut ...
