Climate Change: Does Law Play A Role?

Evaluating the joint effects of climate and land use change on runoff and pollutant loading in a rapidly developing watershed

This study aims at contributing to the vulnerability and adaptation to climate changes (CC) analysis of bordering communities of Togodo Reserve, in order to enhance their resilience. Specifically, the present study attempted to (i) identify the climatic hazards of the WRT; (ii) determine the impacts of climate variability and change on their livelihoods; (iii) assess the socio-economic vulnerability of these communities to food insecurity in relation to CC; and (iv) identify indigenous adaptation strategies to control the effects of CC. The methodological approach used is based on a factual research and a field investigation. The investigation is conducted in two villages around the reserve, namely Deve and Gbohoule. The results showed that climate variability and change were appreciated in different indicators by the local communities living around the WRT: Droughts, flooding, high winds and temperature increase with severe consequences on the communities (famine, destruction of tangible and intangible properties, loss of human life, populations’ migration). The communities are aware that humans are responsible for these events that have become recurrent from 2007 and occur almost every year. According to them, the causes of climate changes are deforestation (due to overexploitation of timber, fuelwood and shifting agriculture), bush fires, rapid increase in population, anger of gods due to irregularities of sacrifices and violations of customs. The communities are vulnerable to main climatic hazards and suffered from food insecurity. The factorial correspondence analysis (FCA)) carried out shows that the perception of the degree of exposure of households to risks depends on their standard of livelihood. Facing these climate events, the populations develop many adaptive strategies of which most are consistent with the national orientations and strategies. These adaptive strategies must be reinforced and supported in order to reduce the vulnerability of these populations to climate changes. Key words: Climate variability and change, communities, livelihood, vulnerability and adaptation, Wildlife Reserve of Togodo.

Impact of climate change on farms in smallholder farming systems: Yield impacts, economic implications and distributional effects

Climate Change and Health: Strengthening the Evidence Base for Policy

We assessed the effects of historical (1931–1998) changes in both land use and climate on the water budget of a rapidly urbanizing watershed, Ipswich River basin (IRB), in northeastern Massachusetts. Water diversions and extremely low flow during summer are major issues in the IRB. Our study centers on a detailed analysis of diversions and a combined empirical/modeling treatment of evapotranspiration (ET) response to changes in climate and land use. A detailed accounting of diversions showed that net diversions increased due to increases in water withdrawals (primarily groundwater pumping) and export of sewage. Net diversions constitute a major component of runoff (20% of streamflow). Using a combination of empirical analysis and physically based modeling, we related an increase in precipitation (2.7 mm/yr) and changes in other climate variables to an increase in ET (1.7 mm/yr). Simulations with a physically based water‐balance model showed that the increase in ET could be attributed entirely to a change in climate, while the effect of land use change was negligible. The land use change effect was different from ET and runoff trends commonly associated with urbanization. We generalized these and other findings to predict future streamflow using climate change scenarios. Our study could serve as a framework for studying suburban watersheds, being the first study of a suburban watershed that addresses long‐term effects of changes in both land use and climate, and accounts for diversions and other unique aspects of suburban hydrology.

Research on the mechanism of how climate change affects cultivated soil organic carbon is the basis for the management of cultivated land quality in the context of climate change. Crop phenological responses to climate change have an important effect on cultivated soil organic carbon as well. However, previous research primarily focused on the independent effects of climate change or crop phenological responses on the changes in soil organic carbon, and few studies have analyzed the changes in cultivated soil organic carbon under the combined influence of both factors or quantified their contribution rates to the changes in cultivated soil organic carbon. Based on topsoil samples in 2008 and 2021, annual pre-season and mid-season climate data from 2008 to 2021, and the phenological parameters extracted from the enhanced vegetation index （EVI） time series from 2007 to 2022, a soil organic carbon predictive model was constructed using the random forest algorithm. The total change in soil organic carbon from 2008 to 2021, the change in soil organic carbon under climate change alone, and the change in soil organic carbon under the synergistic influence of climate change and crop phenological responses were simulated. Furthermore, the contributions of climate change and crop phenological responses to the changes in cultivated soil organic carbon were distinguished and quantified. Moreover, the dominant influencing factors of soil organic carbon changes and their spatial distributions were identified and analyzed. The results were as follows： ① Under the synergistic influence of climate change and crop phenological responses, a decrease was observed in soil organic carbon in 74.15% of the cultivated land area in Fujian Province during the years 2008-2021, with an average decrease of 2.20 g·kg-1. Additionally, there was an increase in soil organic carbon in 25.85% of the cultivated area, with an average increase of 1.48 g·kg-1. ②The average contribution rates of pre-season climate, crop phenological responses to climate change, mid-season climate, and phenological changes resulting from cultivars shifts or other adjustments of agricultural measures to soil organic carbon changes were 34.08%, 28.56%, 22.75%, and 14.61%, respectively. Overall, climate change had a greater impact on the changes in cultivated soil organic carbon in Fujian Province than the crop phenological response to climate change. ③ The regions where climate change and phenological response jointly acted as dominant influencing factors held the largest area, accounting for 47.06% of the total cultivated land area in Fujian Province, and the regions where climate change was the dominant influencing factor alone held the second-largest area, accounting for 28.64% of the total cultivated land area. ④ Higher contribution rates of pre-season climate factors and phenological changes resulting from cultivar shifts or other adjustments of agricultural measures tended to be distributed in higher-altitude areas, whereas higher contribution rates of mid-season climate factors and phenological responses to climate change tended to be distributed in lower-altitude areas. These research findings can provide a theoretical basis for decision making regarding the management of cultivated land quality and the safeguarding of food security in the context of climate change.

Chapter 1 - Remote sensing of climate variability: An introduction

The recent changes in Australia’s climate, the likelihood of further changes over the next decades to centuries, and the likely significant impacts of these changes on the Australian livestock industries, provide increasing urgency to explore adaptation options more effectively. Climate and atmospheric changes are likely to impact on the quantity and reliability of forage production; forage quality; thermal stress on livestock; water demands for both animal needs and for growing forage; pest, disease and weed challenges; land degradation processes; and various social and economic aspects including trade. Potential adaptation options are available for moderate climate changes, with these often being variations of existing climate risk management strategies. However, to date there are few Australian examples where these adaptations have been assessed systematically on any scale (e.g. enterprise, regional, whole of industry or national). Nor have many studies been undertaken in a way that (i) effectively harness industry knowledge, (ii) undertake climate change analyses in the framework of existing operational systems, or (iii) assess climate change in the context of other socioeconomic or technical changes. It is likely that there are limits to the effectiveness of existing adaptations under more severe climate changes. In such cases more systemic changes in resource allocation need considering, such as targeted diversification of production systems and livelihoods. Dealing with the many barriers to effective adaptation will require ‘mainstreaming’ climate change into policies covering a range of scales, responsibilities and issues. This mainstreaming will facilitate the development of comprehensive, dynamic and long lasting policy solutions. The integrative nature of climate change problems requires science to include integrative elements in the search for solutions: a willingness to apply integrated rather than disciplinary science and a strengthening of the interface with decision-makers.

Human interference with the climate system is occurring, and climate change poses risks for human and natural systems (IPCC, 2014). In recent decades, changes in climate have caused impacts on natural and human systems on all continents and across the oceans. Evidence of climate-change impacts is strongest and most comprehensive for natural systems. Due to climate change projected by the mid 21st century and beyond, global marine-species redistribution and marine-biodiversity reduction in sensitive regions will challenge the sustained provision of fisheries productivity and other ecosystem services (IPCC, 2014). Spatial shifts of marine species due to projected warming will cause high-latitude invasions and high local-extinction rates in the tropics and semi-enclosed seas. Species richness and fisheries catch potential are projected to increase, on average, at mid and high latitudes and decrease at tropical latitudes (IPCC, 2014). The Benguela Current Large Marine Ecosystem (BCLME) is one of four Eastern Boundary Upwelling Ecosystems (EBUE), highly productive marine subregions. Although they comprise <2% of the global ocean area, they contribute nearly 7% of marine primary production and more than 20% of the world’s marine capture fisheries (IPCC, 2014). Catches in the EBUE are dominated by planktivorous species such as sardine, anchovy, and horse/jack mackerel, and piscivorous demersal species such as hake. Upwelling of nutrient-rich water stimulates primary production which is transferred to mid and upper trophic levels, resulting in substantial fish, seabird, and marine mammal populations. As a result, EBUEs are considered ‘hotspots’ of productivity and biodiversity. Previous research on the BCLME has had little emphasis on climate change. As with the other EBUEs, strong inter-annual and inter-decadal variability in physical oceanography makes it challenging to detect biophysical trends attributed to climate change. Nevertheless, the physical conditions of the BCLME are highly sensitive to climate variability over a range of scales. Despite its apparent sensitivity to environmental variability, there is limited evidence of ecological changes in the BCLME caused by climate change (IPCC, 2014). For example, pelagic fish, benthic crustaceans, and seabirds have demonstrated general shifts in distribution (IPCC, 2014). Even though much of the evidence on the recent climate change comes from remote sensing and outputs from coupled atmosphere-ocean models, it is necessary to link the global trends with local observations to detect the effects of this change on marine living resources in a regional context. In the BCLME region, the combined oceanographic and biodiversity database collected through the Ecosystem Approach to Fisheries (EAF) Nansen Programme is potentially a major source of local data covering climate change and its effect on marine resources in the last 30 yr. However, its contributions to the understanding of climate change effects on the BCLME are rather limited so far, since the huge amount of data collected under the programme has not been fully utilised. Based on data collected through the EAF Nansen programme, together with other relevant data, the NansClim project (2009–2014) was established to identify and describe possible trends and variability in ocean climate and corresponding changes in marine biodiversity and fisheries in the Benguela Current System. Observations of effects of climate variability on marine biota in the past, based on the Nansen database in combination with other data series available from the region, allowed NansClim to document some general responses concerning production and distribution of marine biota to set a baseline of observed effects of climate variability. Some of the species in the region are more poorly studied than others, and one of the tasks of the project was therefore to characterize the life cycle of such species which may be important indicators of future climate change.

Rural communities are subjected to impact of climate change and children are the most vulnerable. Adaptation to climate change poses, great challenge to Zambia, planners and decision makers need to appreciate application of strategic management. The study desired to establish the extent and impact of climate change on realization of children’s fundamental rights in rural agriculture dependent households, management and child protection systems in Zambia as well as to assess key factors of climate change and how it has contributed to inabilities of rural agricultural dependent households to fulfill fundamental rights of children. Contribute to the body of knowledge through proposing some measures that can address climate changes, with strategic management approach, community engagement, integrated with child rights approach. National Climate Change Policy sets two objectives with immediate relevance responding to climate change, public health and need strategic management, decisions: “To promote, strengthen implementation of adaptation and disaster risk reduction measures to reduce vulnerability to climate variability and change.” “To strengthen, institutional and human resource capacity, to effectively and efficiently address all aspects of climate change at, national, provincial, district and local levels.” There is need to strengthen, policies, promote application of prediction models and technologies to determine vulnerability sectors to climate change, support higher learning and research institutions on climate related research that supports child rights governance and protection. The study used combined methodology, action and explanatory. Much of the study methodology was explanatory in nature as it attempted to identify circumstances surrounding the extent and impact of climate change on realization of children’s fundamental rights in rural households. Key results includes Stakeholders, have not appreciated the application of strategic management in their planning and implementation of interventions on climate change with a child right’s lens. Climate change and environmental degradation are creating various crisis situations for children and rural households including social and economic crisis hence increasing vulnerability and poverty.

Climate change is one of the main challenges facing many countries, particularly developing countries, because of its negative impact on their various ecosystems and their socio-economic development, which very often leads them down a slow descent into poverty. This is because climate change can manifest itself in different forms such as climate variability and extreme events (droughts, epidemics, floods, storms and hurricanes), which can affect biodiversity and cause many human and animal diseases and deaths. In fact, the evolution of ecosystems is dependent on climate and environmental change and appears to be closely associated with many emerging or re-emerging diseases. In general, the ecosystems considered to be most exposed to climate change are those located in and around the intertropical convergence zone in particular. They are believed to be closely linked to the occurrence of several emerging diseases, particularly vector-borne diseases. For years, the Republic of Haiti has been experiencing the adverse effects of these global changes with a marked disruption of its rainfall pattern and prolonged periods of drought as well as a pronounced increase in temperatures even in high altitude areas. Although there is evidence that climate change is increasing the frequency of vector-borne diseases and may contribute to increasing the virulence of their pathogens, there are very few studies conducted in Haiti on the relationship between climate change and vector-borne diseases. The purpose of this chapter is to define the interrelationships between climate change and vector-borne diseases in Haiti by identifying avenues of research to better understand the effects of climate change on public health and to make appropriate recommendations to decision-makers to ensure proper management.

The problem of global climate change is one of the most important problems of society. Such relevance is due to the fact that the change in climatic parameters has a significant impact on the economic sphere, the ecological situation, social and political life, and the construction industry. The change in the parameters of climate systems has long been beyond doubt. In recent years, due to the perceived threat of global climate warming, interest in long-term interannual climate fluctuations has increased significantly. Therefore, one of the unquestionably relevant tasks is the monitoring of trends in changes in climatic indicators at the local (regional) level. It is these observations on a regional scale that allow us to detect cyclical fluctuations in meteorological values and further judge the change in the Earth's climate in general. When building urban quarters in difficult natural and climatic conditions, along with urban planning and architectural and planning methods of organizing residential structures, one of the key points is the correct selection of fencing materials and structures. Special attention should be paid to their physical properties, thermal conductivity, specific resistance, optical reflectivity, etc. It is also necessary to take into account the location of the construction site, because due to macro- and micro-scale climate-forming factors (radiation conditions, wind regime, form of meso- and microrelief, vegetation, soil, close proximity to the sea, surrounding buildings, etc.) and their due to joint influence in different areas of the city, the difference in temperature and humidity can be significant. The article examines the peculiarities of the manifestation of climatic changes for the city of Kyiv in the context of engineering and construction adaptation and the selection of building materials to create more comfortable living conditions for the residents of the metropolis. It was established that during the last decades in the city the average annual air temperature increased by 0.7–1.2°С, compared to the climatic norm. The most significant increase in the average monthly air temperature in the modern period in the city is observed in the winter and summer months. According to calculations, the average annual temperature will rise gradually and increase by an average of 2.0–2.5°С. On the basis of this, the necessity of conducting further research, creating scientific and practical recommendations, especially in the conditions of modern megacities, which are a factor in climate formation, has been proven. The article analyzes the impact of changes in climatic factors on the life cycle of buildings.
