Bequest of the Norseman—The Potential for Agricultural Intensification and Expansion in Southern Greenland under Climate Change

Peer-reviewed publication
Décembre, 2017
Groenland

The increase of summer temperatures and a prolonged growing season increase the potential for agricultural land use for subarctic agriculture. Nevertheless, land use at borderline ecotones is influenced by more factors than temperature and the length of the growing season, for example soil quality, as the increasing lengths of dry periods during vegetation season can diminish land use potential. Hence, this study focuses on the quality of the soil resource as possible limiting factor for land use intensification in southern Greenland.

Effect of Climate and Agricultural Land Use Changes on UK Feed Barley Production and Food Security to the 2050s

Peer-reviewed publication
Décembre, 2017
Global

Currently, the UK has a high self-sufficiency rate in barley production. This paper assessed the effects of projected climate and land use changes on feed barley production and, consequently, on meat supply in the UK from the 2030s to the 2050s. Total barley production under projected land use and climate changes ranged from 4.6 million tons in the 2030s to 9.0 million tons in the 2050s. From these, the projected feed barley supply ranged from approximately 2.3 to 4.6 million tons from the 2030s to the 2050s, respectively.

A Slipping Hold? Farm Dweller Precarity in South Africa’s Changing Agrarian Economy and Climate

Peer-reviewed publication
Juin, 2018
Afrique du Sud
Afrique australe

The paper investigates whether farm dwellers in the KwaZulu-Natal (KZN) province of South Africa are subject to a “double exposure”: vulnerable both to the impacts of post-apartheid agrarian dynamics and to the risks of climate change. The evidence is drawn from a 2017 survey that was undertaken by the Association for Rural Advancement (AFRA), which is a land rights Non-Governmental Organization (NGO), of 843 farm dweller households. Data on the current living conditions and livelihoods was collected on 15.3% of the farm dweller population in the area.

Rangeland Livelihood Strategies under Varying Climate Regimes: Model Insights from Southern Kenya

Peer-reviewed publication
Juin, 2018
Kenya
Afrique orientale

Rangelands throughout sub-Saharan Africa are currently undergoing two major pressures: climate change (through altered rainfall and seasonality patterns) and habitat fragmentation (brought by land use change driven by land demand for agriculture and conservation). Here we explore these dimensions, investigating the impact of land use change decisions, by pastoralists in southern Kenya rangelands, on human well-being and animal densities using an agent-based model.

Improving the Matrix-Assessment of Ecosystem Services Provision—The Case of Regional Land Use Planning under Climate Change in the Region of Halle, Germany

Peer-reviewed publication
Juin, 2018
Allemagne

Against the background of climate change, current and future provision of ecosystem services (ES) will also change. The recording of current provision potentials and its development in future is important for adapted regional planning. ES assessments are frequently carried out in the context of expert-based surveys, which have, however, revealed little information to date about uncertainties. We present a novel approach that combines the ES matrix assessment with the Delphi approach, confidence ratings, standardized confidence levels, and scenario assessment.

Land Use Scenario Modeling Based on Local Knowledge for the Provision of Ecosystem Services in Northern Ghana

Peer-reviewed publication
Juin, 2018
Afrique occidentale

The understanding of multiple effects by possible future development is essential for adapted land use planning. This study assessed the potential of land use scenarios for the provision of ecosystem services using local knowledge in two districts of northern Ghana. Local knowledge was gathered through surveys with extension officers, who are regarded as eligible knowledge holders for agricultural land use.

Expansion of Commercial Sugarcane Cultivation among Smallholder Farmers in Uganda: Implications for Household Food Security

Peer-reviewed publication
Juin, 2018
Ouganda

Understanding the impact of commercial agriculture in the face of global change is critical to support strategies that ensure food security and alleviate poverty among households. We assessed the contribution of commercial sugarcane cultivation to household-level food security among smallholder farmers in Busoga sub-region, eastern Uganda. Land use changes are motivated by quick commercial gains rather than sustained food production; a situation that influences food security.

Tropical Protected Areas Under Increasing Threats from Climate Change and Deforestation

Identifying protected areas most susceptible to climate change and deforestation represents critical information for determining conservation investments. Development of effective landscape interventions is required to ensure the preservation and protection of these areas essential to ecosystem service provision, provide high biodiversity value, and serve a critical habitat connectivity role.

Livelihoods on the Edge without a Safety Net: The Case of Smallholder Crop Farming in North-Central Namibia

Peer-reviewed publication
Septembre, 2018
Namibie

Semi-arid Namibia is marginal for agricultural production. Low soil fertility combined with low and variable rainfall restrict the livelihoods of smallholder farmers who often struggle to produce enough food. Although historically, communities have adopted a number of coping mechanisms, climate change threatens to further reduce agricultural production. There are many additional options available to smallholder farmers to adapt to climate change, but they are not necessarily adopting these measures despite having noticed increasing temperatures and declining rainfall.

Predicting the Potential Impact of Climate Change on Carbon Stock in Semi-Arid West African Savannas

Peer-reviewed publication
Décembre, 2018
Burkina Faso

West African savannas are experiencing rapid land cover change that threatens biodiversity and affects ecosystem productivity through the loss of habitat and biomass, and carbon emissions into the atmosphere exacerbating climate change effects. Therefore, reducing carbon emissions from deforestation and forest degradation in these areas is critical in the efforts to combat climate change. For such restorative actions to be successful, they must be grounded on a clear knowledge of the extent to which climate change affects carbon storage in soil and biomass according to different land uses.

Linking Climate Change Adaptation and Mitigation: A Review with Evidence from the Land-Use Sectors

Peer-reviewed publication
Décembre, 2018
Global

There is extensive scientific evidence that both adaptation and mitigation are essential to address the problem of climate change. However, there is still limited knowledge about the possibilities for exploiting the interrelationships between these measures in the design and implementation of climate change activities. In this paper, first the adaptation–mitigation dichotomy and definitions of adaptation and mitigation are discussed.

Evaluating Public Attitudes and Farmers’ Beliefs towards Climate Change Adaptation: Awareness, Perception, and Populism at European Level

Peer-reviewed publication
Mars, 2018
Europe

The scientific understanding of climate change is firmly established; it is occurring, it is primarily due to human activities, and it poses potentially serious risks to human and natural systems. Nevertheless, public understanding of this phenomenon varies widely among farmers and the public, the two-target audience of this paper. This paper introduces two research questions: (1) How climate change is perceived by public-farmers’ nexus; and (2) How perception and populism (as a thin-ideology moved by social forces) interact?
