Impacts of drought-tolerant maize varieties on productivity, risk, and resource use: Evidence from Uganda

Peer-reviewed publication
Outubro, 2019
Uganda

Weather variability is an important source of production risk for rainfed agriculture in developing countries. This paper evaluates the impacts of the adoption of drought-tolerant maize varieties on average maize yield, yield stability, risk exposure and resource use in rainfed smallholder maize farming. The study uses cross-sectional farm household-level data, collected from a sample of 840 farm households in Uganda. The adoption of drought-tolerant maize varieties increased yield by 15% and reduced the probability of crop failure by 30%.

The relevance of sustainable soil management within the European Green Deal

Peer-reviewed publication
Dezembro, 2020
Estados Unidos

The new European Green Deal has the ambition to make the European Union the first climate-neutral continent by 2050. The European Commission presented an ambitious package of measures within the Biodiversity Strategy 2030, the Farm to Fork and the European Climate Law including actions to protect our soils. The Farm to Fork strategy addresses soil pollution with 50 % reduction in use of chemical pesticides by 2030 and aims 20 % reduction in fertilizer use plus a decrease of nutrient losses by at least 50%.

Are land rental markets responding to rising population pressures and land scarcity in sub-Saharan Africa?

Peer-reviewed publication
Janeiro, 2021
Etiópia
Malawi
Tanzania
República Centro-Africana

Although still at incipient stages in most areas, agricultural land markets in sub-Saharan Africa (SSA) are growing rapidly. While the literature on the region’s land markets is expanding, there has been little attention thus far paid to the drivers of land rental prices. We know quite little about whether and how land markets and land contracts respond to meso-scale factors such as spatial variations in land abundance, or to micro-level factors, such as household land endowments.

Exploring land use/land cover changes, drivers and their implications in contrasting agro-ecological environments of Ethiopia

Peer-reviewed publication
Agosto, 2019
Etiópia

This study examined the trends, driving factors, and implications of land use/land cover (LULC) dynamics over the past 35 years (1982–2017) in three watersheds of the drought-prone areas that represent different agro-ecologies of Upper Blue Nile basin, Ethiopia: Guder (highland), Aba Gerima (midland), and Debatie (lowland). The changes in LULC were analyzed by integrating field observations, remote-sensing data (aerial photographs [1: 50,000 scale] and very high resolution [0.5–3.2 m] satellite images), and geographic information systems.

Assessing the capacity and flow of ecosystem services in multifunctional landscapes: Evidence of a rural-urban gradient in a Mediterranean small island state

Peer-reviewed publication
Maio, 2018
Malta

Distinguishing between the ecosystems’ capacity to generate ecosystem services (ES) and the actual use of these service (ES flow) in ES assessment and mapping is important to develop an understanding of the sustainability of ES use. This study assesses the spatial variation in ES capacity and flow in the Mediterranean small island state of Malta. The services included in this study were crop provisioning, beekeeping and honey production, fodder and livestock production, crop pollination, air quality regulation, and aesthetic ES.

Implications of agricultural bioenergy crop production and prices in changing the land use paradigm—The case of Romania

Peer-reviewed publication
Dezembro, 2015
Romênia

The article starts from the premise that agricultural bioenergy crop production has massive influence in changing the land use paradigm in Romania, due the fact that important land surface areas are cultivated with such crops because of the increasing demand of biofuels. The main aim of the paper is to answer a research question: are there any changes in arable land use patterns determined by the increasing of the agricultural bioenergy crop production and what is the pressure on food consumption? The results show that the competition agricultural vs.

Unpacking Indonesia’s independent oil palm smallholders: An actor-disaggregated approach to identifying environmental and social performance challenges

Peer-reviewed publication
Novembro, 2017
Indonésia

Processes of globalization have generated new opportunities for smallholders to participate in profitable global agro-commodity markets. This participation however is increasingly being shaped by differentiated capabilities to comply with emerging public and private quality and safety standards. The dynamics within Indonesia’s oil palm sector illustrate well the types of competitive challenges smallholders face in their integration into global agro-commodity chains.

Elephants over the Cliff: Explaining Wildlife Killings in Tanzania

Peer-reviewed publication
Fevereiro, 2015
Tanzania
África

Many incidents of elephant killings have recently taken place in Tanzania as well as in other African countries. Such events are usually presented as results of the rising global demand for ivory. As we show in this case study, however, not all violence against elephants is driven by the ivory trade. This article presents an event that occurred in West Kilimanjaro in 2009 when numerous villagers chased a herd of elephants over a cliff, killing six of them. Using a ‘web of relations’ approach, we seek to uncover the underlying as well as the immediate factors that led to this incident.

Complementary land use in the Richmond River catchment: Evaluating economic and environmental benefits

Peer-reviewed publication
Agosto, 2019
Austrália

Agricultural land uses can contribute to land degradation, water quality decline, and loss of ecosystem function and biodiversity in the surrounding catchment. Trees can assist in catchment management, and re-afforestation strategies have been implemented in an effort to mitigate agricultural impacts and improve degraded land and waterways worldwide. Re-afforestation strategies often target private land, and their success relies on landholder participation.

Integrated farm management for sustainable agriculture: Lessons for knowledge exchange and policy

Peer-reviewed publication
Janeiro, 2019
Reino Unido
Estados Unidos
Europa

As a response to the environmentally and socially destructive practices of post-war mechanization and intensification, the concept of sustainable agriculture has become prominent in research, policy, and practice. Sustainable agriculture aims to balance the economic, environmental, and social aspects of farming, creating a resilient farming system in the long-term. Over the last few decades, various concepts have been used in research and policy to encourage the adoption of sustainable practices.

Effects of industrial plantations on ecosystem services and livelihoods: Perspectives of rural communities in China

Peer-reviewed publication
Março, 2017
China

This paper addresses the current research void on local community views of changes in ecosystem services associated with rapid land use transformation in the context of plantation-based forestry. This interview-based study, conducted in southern China, aims at assessing the perspectives of local communities of: 1) the effects of Eucalyptus industrial plantations on selected ecosystem services and on local development; and 2) opportunities for future community livelihood development, based on the relations with the government and with forest industry operating locally.

Perceived importance of ecosystem services in the Białowieża Forest for local communities – Does proximity matter?

Peer-reviewed publication
Agosto, 2020
Global

Effective protection of biodiversity in areas of high conservation value requires trade-offs between local use of natural resources and conservation restrictions. The compromise is often difficult to reach, which causes conflicts over the management priorities of existing and potential protected areas. Ecosystem services (ES) perspective offers a promising avenue for diagnosing and reconciling contrasting interests concerning the use of benefits from ecosystems.
