The steady-state treatment of forestry in CGE models
This paper provides a critical examination of the implicit assumption in steady-state forestry modelling, particularly those employed in CGE models. That is, forests are characterised by steady-state conditions. Therefore, a conceptual model is developed to examine if there is a tendency for forest areas to reach some sort of steady-state. The results from the model simulations show that ...

Problems and prospects in the conservation and development of the Himalayan medicinal plants sector
With the advent of a market-orientated economy, the medicinal plants wealth of the Himalaya has become a high price commodity. As a result, many wild populations of valued medicinal plants are declining due to over-harvesting. In order to prevent the further loss of medicinal plants in the wild and, at the same time, to meet the demands of pharmaceutical companies and herbal healers, attempts are ...

Corn stover to sustain soil organic carbon further constrains biomass supply
Sustainable aboveground crop biomass harvest estimates for cellulosic ethanol production, to date, have been limited by the need for residue to control erosion. Recently, estimates of the amount of corn (Zea mays L.) stover needed to maintain soil carbon, which is responsible for favorable soil properties, were reported (5.25–12.50 Mg ha–1). These estimates indicate stover needed to maintain soil ...

Modelling the success of fruit and vegetable marketing
Previous research showed marketing and consumption losses of fruit and vegetables in Brazil to be 18% of turnover. This study develops a scoring guide that can assist commercial establishments and households in evaluating and mitigating the loss potential for fruit and vegetables within their operations. The scoring model separately addresses losses related to products and losses related to ...

The Bonsucro Difference: Responsible Sugarcane Production
Sustainability starts at the source—and Amyris’ feedstock source is sustainably harvested sugarcane, certified by Bonsucro, a global non-profit organization founded by the World Wildlife Fund that ensures responsible sugarcane production, processing, and trade. With the Bonsucro certification, Amyris has achieved new levels of accountability and transparency into the lifecycle of the ...

Find and Monitor Tree Crops for Sustainability
We can monitor agricultural production around the globe using satellites. Recently, there has been an increase in the number of satellites and the frequency and resolution of images being captured. Such large amount of data on a daily and weekly basis can be used with AI to detect crops. Current Best Practices Supply chain companies use manual scouting and surveys up to three times a season ...

Why We Launched Indigo Marketplace
The system by which we grow and distribute grain is well over a hundred years old. In the early 1900s, with significant urban migration, came the need for an efficient way to transport crops from rural areas to city centers. This led to the development of a commodity system, in which growers brought their harvested grain to silos where it was mixed with their neighbors’. Growers were paid a ...

Soil carbon levels in irrigated western corn belt rotations
Proposals promoting the use of massive amounts of crop residues and other lignocellulosic biomass for biofuel production have increased the need for evaluation of the sustainability of cropping practices and their effect on environment quality. Our objective was to evaluate the effects of crop rotation and N fertilizer management and their stover production characteristics on soil organic carbon ...

Bamboo: The Secret Weapon in Forest and Landscape Restoration?
In the world of forestry, bamboo doesn’t always get the credit it deserves. Dismissed as a weed or marginalized in traditional forest management, bamboo could actually play an important role in forest and landscape restoration. With adequate attention, investment, and the right standards in place, it could become a major renewable and sustainable crop—if we can update our outmoded ...

Valuation and Management of Fishing Resources Under Price Uncertainty
The traditional expected-net-present-value methods cannot properly capture the management flexibility and strategic value aspects of a fishery, and may understate its value. Instead, this paper develops a Real Options model to conceptualize and evaluate fishery exploitation flexibility. Specifically, general models to value the opportunity to either exploit or invest in a fishery are presented. ...

A review of the phosphorus content of dry cereal and legume crops of the world
When food scarcity increases, instability in society increases. The majority of food consumed is from cereals and legumes. Phosphorus is essential for crop plant growth and soils are depleted as this element is removed from crop lands with harvested grains/seeds. To sustain yields, inputs of nutrients are required to balance losses. On global and continental/regional bases, we assembled nine ...

Variable Rate Technology: What is it and what are the Benefits?
Every day, as ag professionals, the focus is on the day-to-day needs of the farm, regardless if you’re a farmer, a retailer, advisor, or service provider. We all think about how to answer questions like which seed will perform the best this year, will commodity prices will be favorable, or will this year finally be another golden year like 2008… But, one of the biggest questions is a ...

Can superfoods boost the planet’s health, too?
As demand for African and Asian tree-based superfoods grows, researchers and entrepreneurs eye ways to maximize benefits for the environment. It can seem like new health food fads pop up every week — fads that often fade as quickly as they appear. Two gaining steam lately, though, may be worth a longer look: baobab and moringa. Traditional fare in parts of Africa (and for moringa, Asia as ...
