Net Returns

An econometric land-use model is used to project regional and national land-use changes in the United States under two IPCC emissions scenarios. The key driver of land-use change in the model is county-level measures of net returns to five major land uses. The net returns are modified for the IPCC scenarios according to assumed trends in population and income and projections from integrated assessment models of agricultural prices and agricultural and forestry yields. For both scenarios, we project large increases in urban land by the middle of the century, while the largest declines are in cropland area. Significant differences among regions in the projected patterns of land-use change are evident, including an expansion of forests in the Mountain and Plains regions with declines elsewhere. Comparisons to projections with no climate change effects on prices and yields reveal relatively small differences. Thus, our findings suggest that future land-use patterns in the U.S. will be shaped largely by urbanization, with climate change having a relatively small influence.

Cutting Regimes

<p>Aeroallergens contribute a major climate change impact on human health since warming favours the production and advances the release of plant pollen. This goes in line with a widely observed advance of flowering in response to increasing temperatures. However, documented plant phenological changes vary with species traits, seasons, and sites. Nevertheless, the start and end of flowering dates are known to build a solid baseline for assessing the spatial and temporal patterns in pollen calendars. A closer look at the match/mismatch of flowering and start of pollen season dates reveals considerable differences which may be also indirectly linked to climate change. In this talk, we will present three perspectives related to (1) grassland land use, cutting regimes and agri-environment measures (AEM), (2) post-season pollen transport of an alpine <em>Alnus </em>species, as well as (3) a first climatology of pre-season long-range pollen transport to Bavaria. These selected examples underline the prominent role of land use/land cover (LULC) and pollen transport besides direct temperature mediated climate change effects on flowering for regional pollen calendars.</p>

AbstractChanges in climate and land use are major drivers of biodiversity loss. These drivers likely interact and their mutual effects alter biodiversity. These interaction mechanisms are rarely considered in biodiversity assessments, as only the combined individual effects are reported. In this study, we explored interaction effects from mechanisms that potentially affect biodiversity under climate change. These mechanisms entail that climate-change effects on, for example, species abundance and species’ range shifts depend on land-use change. Similarly, land-use change impacts are contingent on climate change. We explored interaction effects from four mechanisms and projected their consequences on biodiversity. These interactions arise if species adapted to modified landscapes (e.g. cropland) differ in their sensitivity to climate change from species adapted to natural landscapes. We verified these interaction effects by performing a systematic literature review and meta-analysis of 42 bioclimatic studies (with different increases in global mean temperature) on species distributions in landscapes with varying cropland levels. We used the Fraction of Remaining Species as the effect-size metric in this meta-analysis. The influence of global mean temperature increase on FRS did not significantly change with different cropland levels. This finding excluded interaction effects between climate and landscapes that are modified by other land uses than cropping. Although we only assessed coarse climate and land-use patterns, global mean temperature increase was a good, significant model predictor for biodiversity decline. This emphasizes the need to analyse interactions between land-use and climate-change effects on biodiversity simultaneously in other modified landscapes. Such analyses should also integrate other conditions, such as spatial location, adaptive capacity and time lags. Understanding all these interaction mechanisms and other conditions will help to better project future biodiversity trends and to develop coping strategies for biodiversity conservation.

Impacts Of Climate Change

Although Nepal contributes very low emissions of Greenhouse Gases (GHGs) compared to the developed nations, it is the fourth most vulnerable country in the world due to the effects of climate change. These effects have already lead to more natural disasters, loss of biodiversity, increase in mountain snow melt, uncertainty in precipitation, shortage of food, water and energy etc. resulting in devastating impacts on the life of people living in both mountain and plain areas. Climate change therefore is the vital issue in the country. Understanding the potential impacts of climate change, Government of Nepal since last two decades has taken significant initiatives in response to the effects of climate change including the participations in international conventions, the approval of Climate Change National Policy 2067 (2010), and establishment of a high level Climate Change Council (CCC) under the chairmanship of the Rt. Hon'ble Prime Minister of Nepal. In addition, The Ministry of Environment, Science and Technology (MoEST), being the National Designated Authority (DNA) in Nepal for United Nation Framework Convention on Climate Change (UNFCCC), has executed several programmes and projects related to mitigation and adaptation of climate change effects including Clean Development Mechanism (CDM) projects and National Adaptation Programme of Action (NAPA). International Nongovernmental Organizations such as UNFCCC, DANIDA, DFID, UNEP, UNDP, UN-HABITAT, World Bank, Food and Agricultural Organization (FAO), Asian Development Bank (ADB) etc. as well have carried out numerous climate change projects and activities in Nepal in conjunction with various government agencies.Studies have revealed that the major sources of GHGs are from the burning of fossil fuel (75%), land use changes (20%), and other sources (5%). It has also been postulated that the effects of climate change can be significantly reduced through the implementation of land use policy and activities. Ministry of Land Reform and Management (MoLRM), Government of Nepal (GoN) is the central agency in Nepal dealing with the formulation and implementation of land related policies and activities in the country. MoLRM has commenced to formulate the National Land Policy and has planned to complete it at the end of fiscal year 069/70. This policy will definitely assist in mitigating the effects of climate change in the country. Another essential policy for the mitigation of the impacts of climate change in the country is National Land Use Policy which was prepared by MoLRM and has been approved by GoN in 2012, but it is yet to be implemented. One of the important policies that it has focussed on for the mitigation of climate change effects is to increase the present forest coverage to 40% of the total area of the country while protecting the government land by forestation and plantation programmes on degraded lands.

Siem Reap River has played a crucial role in maintaining the Angkor temple complex and livelihood of the people in the basin since the 12th century. Land use in this watershed has changed considerably over the last few decades, which is thought to have had an influence on river. This study was carried out as part of assessing the land use and climate change on hydrology of the upper Siem Reap River. The objective was to reconstruct patterns of annual deforestation from 1988 to 2018 and to explore scenarios of land use 40 and 80 years into the future. A supervised maximum likelihood classification was applied to investigate forest cover change in the last three decades. Multi-layer perceptron neural network-Markov chain (MLPNN-MC) was used to forecast land use and land cover (LULC) change for the years 2058 and 2098. The results show that there has been a significantly decreasing trend in forest cover at the rate 1.22% over the last three decades, and there would be a continuous upward trend of deforestation and downward trend of forest cover in the future. This study emphasizes the impacts of land use change on water supply for the Angkor temple complex (World Heritage Site) and the surrounding population.

Business As Usual

Land-use and climate change are among the greatest threats facing biodiversity, but understanding their combined effects has been hampered by modelling and data limitations, resulting in part from the very different scales at which land-use and climate processes operate. I combine two different modelling paradigms to predict the separate and combined (additive) effects of climate and land-use change on terrestrial vertebrate communities under four different scenarios. I predict that climate-change effects are likely to become a major pressure on biodiversity in the coming decades, probably matching or exceeding the effects of land-use change by 2070. The combined effects of both pressures are predicted to lead to an average cumulative loss of 37.9% of species from vertebrate communities under ‘business as usual’ (uncertainty ranging from 15.7% to 54.2%). Areas that are predicted to experience the effects of both pressures are concentrated in tropical grasslands and savannahs. The results have important implications for the conservation of biodiversity in future, and for the ability of biodiversity to support important ecosystem functions, upon which humans rely.
