Special Issue Information

Dear Colleagues,

Despite much research into technological fixes, to most growers around the world yield reduction due to weed competition represents a persistent, undesirable, and almost inevitable problem. This threat is not new, and the negative impacts of weedy plants on farmers’ livelihood have played a central role in agriculture for thousands of years. Since the 1950s, weed science has responded to this concern by focusing its attention on weed eradication, principally through chemical or mechanical approaches. Many times, this approach to weed management has been successful in terms of securing yield and maximizing farm labor efficiency. Despite this, the “silver bullet” approach to managing weeds has, in the long-term, been challenged by off-target impacts, health and environmental concerns, economic considerations, and the selection and spread of herbicide-resistant biotypes. As a result, there is increased interest among weed scientists to shift from weed eradication to the development of a science-based discipline aimed at assessing the biological, evolutionary, and ecological principles driving the spread, abundance, and impacts of weed populations and communities within agricultural landscapes. This knowledge is, in turn, used to combine multiple approaches in the development of integrated weed programs that help increase the overall sustainability of the agricultural enterprise. The goal of this Special Issue is to contribute to the development of such integrated weed management programs with an emphasis on the agroecological, socio‐economic, and technological dimensions of agricultural sustainability.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Sustainability is an international peer-reviewed open access semimonthly journal published by MDPI.

In the humid tropics of Latin America, considerable proportions of agro-scapes are covered with degraded pastures that were taken over by dense weedy shrub canopies hampering further forest succession. While tree seeds are still constantly dispersed by bats and birds, these often do not reach the soil but got stuck in the dense shrubby vegetation. While manual up-rooting of weedy shrubs or tree replantation is too expensive, we tested if burrowing pigs or trampling cattle can enhance proportions of bare soils for fallow restoration. These hypotheses were tested in on-farm experiments at Igarapé-Açu, northeastern Pará. Soil-opening effects of ten pigs (40 days + nights) and ten oxen (40 overnight stays), respectively, were tested against manual clearing and control on three plots per treatment, respectively. Ground cover percentages of bare soil, weedy shrubs, grasses, and tree species were visually determined in 40 plots/treatment before and directly after treatments, and half a year later (n = 480 samples). Both animal treatments could not really match manual clearing (62%) but pigs reached above 36% bare ground cover, while cattle just 20%. As pigs are almost omnipresent on Amazonian smallholdings and even give a modest economic refund, the use of pigs is recommended to smallholders who want to break up the lush weed layers for the benefit of forest restoration.
