Can economic and environmental benefits associated with agricultural intensification be sustained at high population densities? A farm level empirical analysis

Peer-reviewed publication
Janeiro, 2019
Quênia

Boserup’s pioneering theory holds that rising population density can be accompanied by sustainable agricultural intensification. But can this positive relationship be sustained indefinitely, or are there conditions under which rising population density can lead to declining agricultural productivity? This study utilizes survey data on farm households in Kenya and soil samples on their main maize plots to assess whether Boserupian agricultural intensification is sustainable at high population densities.

Working on the boundaries—How do science use and interpret the nature-based solution concept?

Peer-reviewed publication
Dezembro, 2019
Global

Nature-based solutions (NBS) is the latest contribution to the green concept family. NBS is defined as actions based in nature addressing societal challenges. In this study, we lean on the concept boundary object, broken down into three analytical categories: use, core ideas and granularities, to explore the cohesive and fragmenting powers of the NBS concept, and discuss its future role in green space governance. The study is based on a structured, qualitative review of 112 scientific peer-reviewed publications that use the term NBS.

The agricultural, environmental and socio-political repercussions of Brazil's land governance system

Peer-reviewed publication
Dezembro, 2013
Brasil

Although many contemporary studies of agriculture associate larger properties with higher relative productivity, this assumption has limited relevancy for the analysis of situations in which property owners profit more from large-scale property accumulation itself rather than any superiority in exploitation opportunities offered by increased size. In Brazil, the efficiency-of-scale paradigm has been used to criticize peasant agriculture as unproductive and hide contradictions deriving from land concentration.

The influence of land-use change paradigm on Romania’s agro-food trade competitiveness—An overview

Peer-reviewed publication
Janeiro, 2017
Romênia

The current transformations of the Romanian agricultural sector have imposed new paradigms in using the land resources. The objective of this study is to assess Romanian agro-food products competitiveness on world market, in terms of land use changing paradigms. The research question is whether the land is cultivated with crops which are competitive on world market. For assessing agro-food competitiveness, Balassa index is calculated. The findings show relative performance for barley, maize, triticale, wheat, poultry meat, oilseeds, and tobacco.

Livestock-derived greenhouse gas emissions in a diversified grazing system in the endangered Pampa biome, Southern Brazil

Peer-reviewed publication
Maio, 2018
Brasil
Grécia
Estados Unidos

Discussions about climate change have repeatedly regarded livestock as responsible for a significant contribution of greenhouse gas emissions. However, proper management schemes for livestock production may contribute to a reduction in emissions and, at the same time, induce optimization of production systems and intensification of food production.

Protecting our prairies: Research and policy actions for conserving America’s grasslands

Peer-reviewed publication
Agosto, 2020
Estados Unidos

Grasslands are among the most endangered ecosystems in the world. They supply vital resources for society, support an abundance of wildlife species, and store rich carbon reserves beneath their surfaces. Despite this, only a fraction of original grasslands in the United States now remains, and their rate of conversion to cropland has recently reaccelerated. This paper discusses opportunities that are immediately available to reduce the loss of U.S. native grasslands (i.e., prairie) and advance toward collective goals in grassland conservation.

Part-time amenity migrants: Revealing the importance of second homes for senior residents in a transit-oriented development

Peer-reviewed publication
Outubro, 2016
Suécia

Transit-oriented development (TOD) has been proposed as a model for sustainable urban and regional development beyond the troubled heritage of modernistic planning. Key to TOD is mixed use and reduced dependence on private cars. However, functionalistic land-use divides persist in the principles of TOD, such as the division between leisure and work and between permanent residences and second homes. These divides relate to, and are emphasised by, a strong focus on urban qualities within the TOD discourse, while discussions on landscape amenities are set aside.

Introducing nature-based solutions into urban policy – facts and gaps. Case study of Poznań

Peer-reviewed publication
Maio, 2019
Global

Cities often don’t appreciate the benefits of green infrastructure (GI) enough. To recognise the extent to which green infrastructure and nature-based solutions (NbS) are present in the urban policy, we conducted a review of planning, strategic and programming documents of Poznań City as a Case Study.

Attitudes of a farming community towards urban growth and rural fragmentation—An Auckland case study

Peer-reviewed publication
Dezembro, 2016
Nova Zelândia

As the global population continues to increase, rural areas are expected to accommodate future growth at the same time as continuing to feed growing populations. This tension is greatest on those who farm land that is earmarked for future urban growth. Yet, little is known about the attitudes and values of the affected rural farming communities or farmers’ perceptions of the challenges and opportunities that population growth presents.

Forestry paradigms and policy change: The evolution of forestry policy in Britain in relation to the ecosystem approach

Peer-reviewed publication
Novembro, 2015
Reino Unido
Território Britânico do Oceano Índico

Forestry policy and practice in Britain has been subject to a series of paradigm changes since the establishment of the Forestry Commission in 1919. Drawing on a documentary analysis of legislation, published policy statements, commentaries and scholarly critiques, this paper argues that British forestry policy has undergone three significant paradigm shifts since it was first mooted in the late 19th century.

Who are forest-dependent people? A taxo nomy to aid livelihood and land use decision-making in forested regions

Peer-reviewed publication
Novembro, 2016
Global

The relationship between forests and people is of substantial interest to peoples and agencies that govern and use them, private sector actors that seek to manage and profit from them, NGOs who support and implement conservation and development projects, and researchers who study these relationships and others. The term ⿿forest-dependent people⿿ is widely used to describe human populations that gain some form of benefits from forests.

Green lights in the Greenbelt? A qualitative analysis of farm investment decision-making in peri-urban Southern Ontario

Peer-reviewed publication
Agosto, 2016
Canadá
Estados Unidos

The survival of farms requires innovative adaptation and investment to take advantage of the characteristics of the peri-urban environment. In Ontario, Canada, the Provincial Government passed in 2005 the Greenbelt Act that delimits Ontario’s Greenbelt—an area of 1.8 million acres where land is protected from development around the metropolitan region of the Greater Golden Horseshoe. This paper presents research on farm-level analysis of farmers’ investment decision-making aiming at understanding the impact of Ontario’s Greenbelt on farm investment.
