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
Junho, 2018
Alemanha

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
Junho, 2018
África Ocidental

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
Junho, 2018
Uganda

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
Setembro, 2018
Namíbia

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
Dezembro, 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
Dezembro, 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
Março, 2018
Europa

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?

Re-Evaluating the Climate Factor in Agricultural Land Assessment in a Changing Climate—Saskatchewan, Canada

Peer-reviewed publication
Março, 2019
Canadá

We established the statistical relationships between seasonal weather variables and average annual wheat yield (Hard Red Spring and Durum wheat: Triticum spp.) for the period of 1979–2016 for 296 rural municipalities (RMs) throughout six soil zones comprising the arable agricultural zone of Saskatchewan, Canada. Controlling climate variables were identified through Pearson’s product moment correlation analysis and used in stepwise regression to predict wheat yields in each RM.

Assessing the Role of the Perceived Impact of Climate Change on National Adaptation Policy: The Case of Rice Farming in Indonesia

Peer-reviewed publication
Maio, 2019
Indonésia

Climate change (CC) is one of the primary threats to the agricultural sector in developing countries. Several empirical studies have shown that the implementation of adaptation practices can reduce the adverse effects of CC. The likelihood of farmers performing adaptation practices is mostly influenced by the degree of CC impact that they perceive. Thus, we identified the characteristics of farmers that affect the degree of the CC impact that they perceive. We used data from the Indonesian Rice Farm Household survey consisting of 87,330 farmers.

Microhabitats Affect Population Size and Plant Vigor of Three Critically Endangered Endemic Plants in Southern Sinai Mountains, Egypt

Peer-reviewed publication
Junho, 2019
Egito

Endemic species on mountains often have narrow altitudinal ranges and are more threatened at the higher altitudes, especially with climate changes. However, plants could use special microhabitats at the mountain tops as proper places for surviving the climate change (i.e., refugia). We assessed population attributes of three critically endangered endemic species (Primula boveana Decne ex Duby, Rosa arabica Crep., and Silene leucophylla Boiss.) in two growing seasons (2006/2007 and 2013/2014), differing in the received rainfalls in microhabitats at the high mountains of southern Sinai.

Habitat Climate Change Vulnerability Index Applied to Major Vegetation Types of the Western Interior United States

Peer-reviewed publication
Julho, 2019
Global

We applied a framework to assess climate change vulnerability of 52 major vegetation types in the Western United States to provide a spatially explicit input to adaptive management decisions. The framework addressed climate exposure and ecosystem resilience; the latter derived from analyses of ecosystem sensitivity and adaptive capacity. Measures of climate change exposure used observed climate change (1981–2014) and then climate projections for the mid-21st century (2040–2069 RCP 4.5).
