The Chilean Water Allocation Mechanism, established in its Water Code of 1981
A long narrow strip of land (no more than 430 km wide) between the Andes and the Pacific Ocean, Chile stretches 4,630 km from near lat. 18°S to Cape Horn (lat. 56°S), including at its southern end the Strait of Magellan and Tierra del Fuego, an island shared with Argentina. In the Pacific Ocean are Chile's several island possessions, including Easter Island, the Juan Fernández ...

The determinants of local collective action on erosive runoff. An analysis of farmers' geographical proximities in Upper Normandy, France
Runoff disregards territorial boundaries, affects farmers as well as other users of space, and necessitates collective action if it is to be combatted. In this article, based on the case of Upper-Normandy, we show that geographical proximity can play a determining role in the struggle against erosive runoff, and we present a new tool for analysing relations of proximity between farmers. First, we ...

The optimization of the paddy field irrigation scheduling using mathematical programming
In planting rice, a significant amount of irrigation water is required to prepare the farmlands and do transplanting and this is directly related to the number of machines and workers available; that is, the more the length of plowing and transplanting process due to the lack of required machinery and labor, the more the water volume consumed. Therefore, in such conditions, it is important to ...

Scale of biomass production from new woody crops for salinity control in dryland agriculture in Australia
There is scope internationally to utilise surplus and degraded agricultural land for biomass crops that might also be environmentally beneficial. For example, dryland salinity in southern Australian could be ameliorated using profitable woody biomass crops. A model was developed to predict biomass production from such woody crops. At a biomass price of A$35/t (green) and a water use efficiency of ...

Is organic farming climate friendly?
Think organic farming is climate friendly? You might want to think again. A study published recently in the journal Agriculture and Human Values suggests that as organic agriculture emulates conventional industrial agriculture, the environmental benefits may not be the slam-dunk that Earth-loving proponents might like them to be. It’s well known that organic practices offer climate ...

What Percentage of Cropland Acres Are Absentee Owned?
According to the USDA’s 2014 Tenure, Ownership, and Transition of Agricultural Land (TOTAL) Survey, 39% of the 916M agricultural acres in the U.S. are rented. And a good portion of those rented acres are owned by individuals or partnerships who do not directly farm the land. There is speculation that absentee owners, cropland owners who don’t live on the farm they own, are a growing ...

Population growth data is bad news for the climate
The demographers may have got it wrong. New projections say the population of the planet will not stabilise at 9 billion sometime this century. In fact, there is an 80% likelihood that, by 2100, it will reach at least 9.6 bn − and maybe rise as high as 12.3 bn. The latest data, published in the US journal Science, has profound and alarming implications for political stability, food ...

The European Grassland Butterfly Indicator: 1990–2011
This report presents the European Grassland Butterfly Indicator, based on national Butterfly Monitoring Schemes (BMS) in 19 countries across Europe, most of them in the European Union. The indicator shows that since 1990 till 2011 butterfly populations have declined by almost 50 %, indicating a dramatic loss of grassland biodiversity. This also means the situation has not improved since the ...

10 messages for 2010 - agricultural ecosystems
Introduction: biodiversity, agriculture and the Common Agricultural Policy (CAP) Europe"s agricultural sector has received sustained public support under the Common Agricultural Policy (CAP) over the last 50 years. This support has evolved alongside growing recognition and awareness of the strong links between agricultural production and biological diversity conservation. On one hand, it ...

Science for Environment Policy
The economic impact of climate change on European agriculture A new study has estimated how changes to climate might affect the value of European farmland. Based on data for over 41 000 farms, the results suggest that their economic value could drop by up to 32%, depending on the climate scenario considered- Farms in southern Europe are particularly sensitive to climate change and could ...

Why are some French farmers sludge-takers? Some agronomic and socioeconomic explanations
The continued spreading of household wastewater sludge on farmlands is a major economic and environmental issue. This practice is being challenged in France, mainly through pressure from the agrifood business. Here, by means of an agronomic analysis performed on 60 farms, we show the relevance of the following variables: proportion of arable land, technical performance of the farm, and quality ...

CORNucopia of Opportunity in the Heartland: Or Just More Feed for the Political Cattle?
We now live in a carbon constrained world. Fears of human induced climate change are bringing about changes in government, corporate and consumer behaviors. Investments in renewable energy are increasing, corporations are greening everything from their supply chain to their vehicle fleet, and consumers are seeking to minimize their ecologic footprint as well. Are some of our greening efforts ...

A Saline Duper Wheat that Tolerates Higher Salt Concentrations!
In the past few decades, agricultural land has been largely lost, and increased salinity in soils around the world has received much attention. Nowadays, nearly 8% of the world's arable land can no longer be used for crop cultivation due to salt pollution, and more than half of the world's countries are affected. Wheat is the second largest grain grown after corn and grows more on Earth than any ...

Indigo`s Living Map of the World`s Food System
Two weeks ago, at the inaugural Beneficial Ag event in Memphis, Indigo was proud to participate in a growing community of innovators from across the food system. One of the questions we asked ourselves was, “What are the technological capabilities needed to catalyze the beneficial agriculture movement?” We believe a new way for seeing the global food system is part of what’s ...

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 ...

Regenerative agriculture and climate change
The term “regenerative agriculture” is gaining prominence in climate-related conversations. It dates back to the 1980s when Robert Rodale coined the term, “regenerative organic agriculture” as way to express that organic should be more than simply avoiding chemical inputs. The term has been defined and re-defined by many different authors, sometimes describing very ...

Why land rights should be on the Rio+20 agenda
As government leaders prepare for next month’s UN Conference on Sustainable Development (Rio+20) in Brazil, one issue is conspicuously absent from the agenda: land rights. Strong property rights—the rights for people to access, control, transfer, and exclude others from land and natural resources—create incentives to invest in sound land management and help protect land from ...
