Automation in steep terrain agriculture: an optimal controller to prevent tipping and slipping of tethered robots on slopes

Josephine Anna Eleanor Hughes, Max Mirko Polzin

Autonomous robots have the potential to fundamentally transform conventional farming methods, e.g. by enabling economically viable farming of sloped arable land. However, navigation on slopes in harsh conditions is challenging for robots as they must be pr ...

Innovation capacity of the agricultural sector: network of productive interactions, knowledge transfer and differentiation mechanisms

Camille Marguerite Aouinait

Economic growth is increasingly explained and driven by knowledge acquisition and firmsâ capabilities to adapt to new evolving situations to fit economic, societal and environmental frames. Strategic behavior of private companies in differentiating and p ...

Land-use change affects phosphorus fractions in highly weathered tropical soils

Thomas Guillaume

Deforestation and land-use change in tropics have increased over the past decades, driven by the demand for agricultural products. Although phosphorus (P) is one of the main limiting nutrients for agricultural productivity in the tropics, the effect of lan ...

Tropical soils degraded by slash-and-burn cultivation can be recultivated when amended with ashes and compost

Alexandre Buttler, Vincent Eric Jules Jassey, Bjorn Jozef Maria Robroek, Robert Thomas Edmund Mills, Justine Marie Gay des Combes

In many tropical regions, slash-and-burn agriculture is considered as a driver of deforestation; the forest is converted into agricultural land by cutting and burning the trees. However, the fields are abandoned after few years because of yield decrease an ...

Land use controls stream ecosystem metabolism by shifting dissolved organic matter and nutrient regimes

Amber Joy Ulseth

Stream ecosystem metabolism integrates production and respiration of organic matter and plays a fundamental role in the global carbon (C) cycle. Several studies have identified distal and proximal physical controls, for example, land use and transient s ...

Suppressed convective rainfall by agricultural expansion in southeastern Burkina Faso

Marc Parlange, Gabriel George Katul, Natalie Claire Ceperley, Theophile Mande

With the green economy being promoted as a path to sustainable development and food security within the African continent, the influx of agricultural land is proliferating at a rapid pace often replacing natural savannah forests. Where agriculture is prima ...

Evolution of the global virtual water trade network

Andrea Rinaldo

Global freshwater resources are under increasing pressure from economic development, population growth, and climate change. The international trade of water-intensive products (e.g., agricultural commodities) or virtual water trade has been suggested as a ...

Structure and Controls of the Global Virtual Water Trade Network

Andrea Rinaldo, Samir Suweis

Recurrent or ephemeral water shortages are a crucial global challenge, in particular because of their impacts on food production. The global character of this challenge is reflected in the trade among nations of virtual water, i.e. the amount of water used ...

Successes and limitations of phytotechnologies at field scale: outcomes, assessment and outlook from COST Action 859

Jean-Paul Schwitzguebel

Purpose Many agricultural and brownfield soils are polluted and more have become marginalised due to the introduction of new, risk-based legislation. The European Environment Agency estimates that there are at least 250,000 polluted sites in the member sta ...

Dualities in plant tolerance to pollutants and their uptake and translocation to the upper plant parts

Jean-Paul Schwitzguebel

There is a duality in plant tolerance to pollutants and its response to the pollutants’ stress. On the one hand some plants, (hyper)tolerant to heavy metals, are able to hyperaccumulate these metals in shoots, which could be beneficial for phytoremediation ...

COMMONSense Net: A Wireless Sensor Network for Resource-Poor Agriculture in the Semiarid Areas of Developing Countries

Jean-Pierre Hubaux, Jacques Panchard

We describe the on-going design and implementation of a sensor network for agricultural management targeted at resource-poor farmers in India. Our focus on semi-arid regions led us to concentrate on water-related issues. Throughout 2004, we carried out a s ...

Multimedia fate and human intake modeling: Spatial versus nonspatial insights for chemical emissions in Western Europe

Multimedia fate and multipathway human,exposure models are widely adopted in assessments of toxicological risks of chemical emissions at the regional scale. This paper addresses the question of how much spatial detail is necessary in such models when estim ...
