Adesina, F, Odekunle T.  2021.  Climate Change and Adaptation in Nigeria: Some Background to Nigeria's Response-III, 2021/10/15. Abstract

This concluding part of the larger paper evaluates some aspects of the Nigeria's vulnerability to the impacts of climate change and discusses potential adaptation strategies that can help in coping with or reducing the impacts of the change in the agriculture and forestry sectors. The vulnerabilities of the various parts of the country were computed, using a wide range of socio-economic parameters and physical environmental factors. The results show that there had been important variability in the rainfall and temperature regimes which 'expose' the country to severe impacts of climate change. The vulnerability assessment further shows that the country's resilience to climate change impact is very weak especially in the Sudano-Sahelian zone. Considering the nature of the vulnerabilities, the paper proposed a number of adaptation strategies mainly in the Agriculture and Forestry sectors. The paper concludes that development and implementation of appropriate policy instrument will be important in ensuring that the country effectively addresses its adaptation challenges.


To make the MDGs a reality, especially as it affects the built environment, and to conform with the UN Agenda 21 and Habitat Agenda summed up in the concept of urban physical sustainability, there is a need to rapidly improve the quality of decisions on land use, conversion and urban renewal in developing countries, especially with regards to physical developments. The potentials of SDSS in determining optimum sites for physical developments within the built environment was the focus of this study. The SDSS developed took into consideration existing and future planning scenarios with the aim of creating a sustainable built environment. To do this, a framework for capturing existing landuse was generated and the SDSS used to generate physical development expansion scenarios of the Obafemi Awolowo University, Nigeria. The system facilitated integrated procedures for determining optimal sites for incremental physical development in such a way as to minimize impact on other aspects of development. The application of this system shows that planning especially as it relate to the urban environment can be made more flexible, dynamic and responsive to timely decisions on geographic space.

Entrepreneurship is a tool for facilitating rural economic development, which is becoming increasingly needed to respond to the growing impacts of accelerating climate change on rural women’s livelihoods in less developed countries creating constraints on sustainable development. This study examines the awareness of and impacts of climatic changes as perceived by women in South West Nigeria in diverse vegetation zones. It elicits the challenges facing women and which constrain their entrepreneurial activities. It therefore identifies potential adaptation strategies and opportunities, including drawing on a review of wider developments in at international development level, such as technological, institutional and infrastructural innovations. The study employed explorative, mixed approaches, including quantitative and qualitative methods. Five hundred and ninety-five questionnaires were administered to selected respondents through multi-stage sampling technique, while Focused Group Discussions (FGDs) were used to solicit qualitative data from two hundred and forty women. Quantitative data were analysed with SPSS for descriptive and analysis of variance, and Atlas ti. was used to thematically analyse qualitative data. Findings showed that women have high levels of awareness of changes in their climate. Analysis of variance revealed that most of the women involved in crop farming in the vegetation zones showed better understanding than women in other livelihood. They strongly agreed (with mean of approximately 5) that climate change had greatly affected soil fertility, caused less predictable, and prolonged the dry season. Over 90% of the women perceived significant impacts of these changes on their livelihood activities. Overall, there were no clear divergences in women’s attitudes towards innovation and entrepreneurship between the vegetation zones and a relatively high expectation of government support. Wider review of current practice and innovations highlights a wide range of new opportunities for building women’s adaptive capacity which could directly or indirectly catalyse increased entrepreneurship amongst women. Furthermore, the involvement of local authorities and community-based organisations, as well as diverse public and private actors, in the development of adaptation strategies is crucial to achieving this.

Faiyetole, A, Adesina F.  2017.  Regional Response to Climate Change and Management: An Analysis of Africa's Capacity, 2017/09/19. 9 Abstract

PurposeThe mainstream climate change community has primarily concerned itself with mitigation and adaptation strategies, both of which require monitoring and prediction. These four inter-connected response actions (mitigation, adaptation, monitoring and prediction) constitute the main strategies for managing climate change. This paper aims to weigh in on policies and societal coordination for effective management of the earth’s climate with respect to these four elements in Africa because of its socioeconomic peculiarities.
The Delphi experts’ method backed by questionnaires was used to obtain relevant data for the study. The questionnaires were distributed to professionals dealing with issues related to climate change response and sustainability in various parts of the world, with a focus on Africa.
With respect to the strategies that are most needed for effective climate change actions in Africa, government’s policies, activities and decisions rank highest at 1.20 with a p -value of < 0.001, and financing is next at 0.93, mitigation is 0.83, prediction is 0.76 and adaptation is 0.68 ( p = 0.048), at the 5 per cent cutoff. Also, for the most appropriate approaches to managing climate change across Africa, regional efforts are at least 8 times more effective than country-wide approaches, followed by continental efforts at 6.51 times, international cooperation at 3.99 times and inaction at 0.00 times.
The paper concludes that a holistic climate change management approach is important in Africa to contain the impacts of climate change in the continent.

Adegboyega, S, Oyetunji I, Olajuyigbe A, Adesina F.  2017.  GIS-based site suitability and vulnerability assessment of telecommunication base transceiver station facilities in Ibadan metropolis, Nigeria, 2017/08/18. 9 Abstract

The study assessed GIS capability in siting of base transceiver stations (BTS) to ensuring optimum spatial coverage of signal while minimizing their health impacts. It therefore evaluated the spatial pattern of BTS, determined areas vulnerable to health hazards related to them and identified most suitable locations for siting the BTS in Ibadan metropolis. Digital elevation model, IKONOS, geographic locations of the BTS and administrative map of Ibadan were used. Images and map were georeferenced using ArcGIS 10.2 version. Features such as drainage, road network, buildings among others were extracted from the IKONOS image. Nearest neighbourhood analysis was performed to investigate the nature of the BTS distribution. Buffering analysis was carried out to identify the numbers of buildings at risk of radiation emission from BTS based on National Environmental Standards and Regulation Enforcement Agency (NESREA) 10 m distance regulation. View shed analysis was performed to determine signal strength across the study area. Multi-criteria analysis (MCA) and sensitivity analysis were carried out to generate BTS suitability index maps. The finding showed that BTS distribution pattern was dispersed with z-score of 4.39 and there was less than 1% likelihood that this dispersed pattern could be the result of random chance (P value = 0.01). The study revealed that 934 buildings with 13,387 population were found within 10 m from the BTS and thus vulnerable to possible health hazards of harmful radiation. The study proposes creation of 11 new BTS sites that would increase strong signal strength coverage across the study area. It canvassed for further researches on the effects of long-term exposure to radiation among people living around BTS in Nigeria. © 2017, Società Italiana di Fotogrammetria e Topografia (SIFET).

Maduekwe, N, Adesina F.  2017.  Remittances economy, remittances landscape: an analysis of the economic and socioecological implications of remittances to households in South Eastern Nigeria, 2017/02/01. 82 Abstract

This study evaluated the level of household dependence on remittances, its uses and linkages with landscape/environmental conditions in South Eastern Nigeria. The study area is a landscape unit defined by the Idemili River Basin of Anambra State. The concept of socio-ecological systems provided the basis for an integrated assessment of remittances environment linkages using primary data from a survey of 840 households in 25 localities in the basin and landscape data from a Nigerias at 32 m resolution image dataset. Based on this, linear and non linear regression modelling of locality level relationships between four indicators of household remittances (HR) and a key landscape variable (vegetation cover density-VCD) was implemented. About 45 % of the households had access to remittances; 10 % of receiving households depended on it as their main income source; and over 87 % used the receipts mainly to meet basic household needs. Only 4 % of the households used it in activities that directly affected the vegetation cover. The linear and non linear relationships between the indicators of HR and VCD were generally weak (R2 < 0.250). However, the pattern of relationship was different for various indicators of HR. It was inverse for locality aggregate (total) and average HR and positive for level of household access to remittances/locality. This illustrates the complex relationship between remittances and landscape variables in the basin. The study shows that the impact of remittances on households and the environment in the region is both positive (through the alleviation of poverty and land pressure) and negative (through reduction of vegetation cover density).

Akinbami, C, Olawoye J, Adesina F.  2016.  Rural Women Belief System and Attitude Toward Climate Change Mitigation and Adaptation Strategies in Nigeria, 2016/07/29. :49-69. Abstract

Climate change has affected both the natural and human systems, of which the women in the rural areas and their livelihood practices are the mostly affected. This study was conducted in some selected rural communities of Osun state in Southwest, Nigeria among women involved in different livelihood practices to find out issues about climate change impacts on the rural women such as: Are the rural women aware of climate change and its impacts? How prepared are they for climate change mitigation and adaptation strategies? Are there any socio-cultural barriers to combating climate change? The study therefore focused attention on their beliefs, attitude and perception about climate change. It also discussed the barriers their beliefs and attitude posed to the establishment and implementation of mitigation and adaptation strategies in the rural areas. Focus Group Discussions, in-depth interview and questionnaire were employed to capture awareness, actual beliefs and attitude, the effect of such attitude and beliefs on adopting mitigation and adaptation strategies. Data collected were analysed using Atlas.ti and SPSS. Most of the women in the rural areas are aware of the impacts of climate change in their environment, especially, on their livelihoods. However, the awareness level has not impacted on them positively to adopt any mitigation and adaptation strategies. This is due to their belief system that climate change is not a consequence of anthropogenic activities. Recommendations were made as to how these problems could be solved for the women in the rural areas to embrace mitigation and adaptation strategies.

Faiyetole, A, Adesina F, Oyebisi T.  2016.  An Analysis of the Costs and Benefits of Actions or Inactions for Africa under Variable Climate Policies, 2016/06/27. Special edition: Environment and Sustainable Development in the 21st Century:pp96-104. Abstract

The four forecasted climate policy scenarios or representative concentration pathways (RCP), informed the findings of the fifth assessment report (AR5) of the intergovernmental panel on climate change (IPCC). Depending on the emissions levels, economic status and population growth, the climate pathways, if adopted, would imply different costs and benefits to different countries or regions. In pertinence, with respect to economic status, the combined gross domestic product (GDP) of the ten highest emitters of Carbon dioxide in Africa, for instance, is currently less than for the seventh global emitter. In this study, stochastic analysis of the mitigative costs for RCP 2.6, 4.5, 6.0 and 8.5 (Wm-2) radiative forcing for CO2 were conducted from 2010 to 2100 for Africa and the Middle East (AME) region. For example, RCP 6.0 posed the highest % of GDP loss in 2030, and thereafter, RCP 2.6 maintained the highest % of GDP loss through the century. It is therefore arguable that AME in general, and Africa in particular, could pursue a hybrid of the four climate pathways in ensuring the associated economic benefits are maximized for the continent.

Ologeh, I, Akarakiri J, Adesina F.  2016.  Promoting Climate Smart Agriculture Through Space Technology in Nigeria, 2016/01/17. :99-112. Abstract

Agriculture is one of the sectors mostly affected by climate change. Nigerian farmers have been losing their harvests to the impacts of climate change leading to lower crop production and poorer livelihoods. Climate Smart Agriculture (CSA) is an adaptation strategy that helps rural farmers to be resilient to and cope with the effects of climate change. It can be improved through the use of space technology by empowering key actors, providing them with reliable weather forecasts at the right time.This paper presents an assessment of already adopted space applications in Nigerian agricultural sector; the distribution of mobile phones to rural farmers by government for easy access to CSA information from extension workers. It is also a policy research on other unpractised space applications, especially the conversion of geo-data to relevant information on climate and hazards that can help local farmers, nourishing them with timely agricultural advice which enables them to have higher crop yields and a more efficient use of seeds, water and fertilizers. The farmers will also receive early warnings for drought, flooding and/or diseases on their mobile phones, thus maximizing its use. The results of this paper will be useful for crop production agencies and NGOs in Nigeria and Sub-Saharan Africa.

Adesina, F, Gadiga B.  2014.  The Role of Shelterbelts in Vegetation Development of Desert Prone Area of Yobe State, Nigeria, 2014/11/18. 6 Abstract

Environmental degradation is a major contemporary globally issue that is bedeviling most parts of the arid environment. This is due to the several centuries of poor management of the earth’s natural resources, and the increasing pressure associated with rapid population growth. This study assesses the influence of some selected shelterbelts in arid environment of Yobe State, Nigeria on vegetation characteristics. This is with intention of identifying its significance in fighting desert encroachment. In the selected shelterbelts, sample plots (quadrats) measuring 30 m ² in dimension was systematically located at an interval of 200 meters. On the adjoining areas of the shelterbelt, control quadrats of similar size were located at the same interval and at a distance of 100 meters from the belt. The vegetation characteristics analyzed in this study include height, diameter, density, frequency and diversity. SPSS, CANOCA and PAST ecological software were used in analyzing the data collected. The result shows that there is significant difference (P<0.005) between all the vegetation characteristics in the shelterbelt sites and the control sites except species diversity. This shows that shelterbelts are necessary tool in fighting desertification in the area as they enhance the vegetation status thereby protecting the soil against wind erosion which is one of the major ecological problems of desertification.

Adesina, F, Maduekwe N.  2014.  Multi Level Modelling of the Linkages Between Vegetation Cover Dynamics and Socio-economic Factors in the Idemili River Basin of Anambra State, Nigeria, 2014/09/02. Abstract

This study assesses the relationships between socio-economic factors and the spatial dynamics of vegetation cover inthe Idemili River Basin of South Eastern Nigeria. It is based on a socio-ecological systems dynamics modeling
concept highlighting locality scale relationships between vegetation cover densities and socio-demographic,
economic and socio-cultural factors in the basin. The modeling was implemented using regression techniques with
pixel level NDVI indicators of vegetation cover density developed from remote sensing image datasets and
indicators of eight socio-economic factors developed from a household survey of the basin. NDVI values for the
basin ranged from -.117 to .410 indicating a high level of human impact on vegetation. Modeling results showed that
bivariate relationships between vegetation cover dynamics and socio-demographic variables were the most
significant, with R Square values > .60 for linear and nonlinear models. Vegetation cover density had high inverse
correlations with population, urbanization levels and number of households in localities. Population/urbanization
status of localities was also the most significant principal component or underlying dimension linked to spatial
dynamics of vegetation cover in the basin accounting for 50% of factor variations. Relationships between vegetation
cover densities and economic factors (occupational and household energy patterns) and socio-cultural factors
(environmental knowledge, values and governance) were weaker, and less significant . The study showed that factor
interactions are a prominent aspect of vegetation-society relationship in the basin with both adverse and beneficial
implications to vegetation cover.

Patience, U, Adesina F, Orimoogunje O.  2014.  Plantation Agriculture as a Driver of Deforestation and Degradation of Central African Coastal Estuarine Forest Landscape of South-Western Cameroon, 2014/01/01. Abstract

Plantation agriculture has a long history of establishment in Cameroon and is increasing at an unprecedented rate with detrimental impacts on coastal estuarine forest landscape. Remote sensing data from Landsat imageries and geographic information system (GIS) techniques were used to analyse changes in the areal extent of plantations within the coastal Atlantic estuarine forest complex area of Cameroon between the periods 1986, 2000 and 2011 to ascertain the extent of deforestation due to plantation agriculture. Given the base year of 1986(67,792 ha of plantation), the results showed a 67 and 47 % decrease in the dense coastal estuarine forest coverage in 2000 (14,032 ha) and 2011 (24,564 ha), respectively, in the area and an increase in the area occupied by plantations (51,295 ha in 2000 and 68,340 ha in 2011) giving an annual loss of 3.4 % estuarine forest complex and an increase in plantation area of 0.03 % from the periods 1986 to 2011. There is need for better plantation management practices and policies to curb further loss in estuarine forest cover with consequent implications on the Wouri estuary.

The African Ministerial Council on Science and Technology agreed that drought is one of the major environmental problems thatis afflicting the African continent, with its consequent negative impacts on the socioeconomic development of the affected
areas. It is within this context that this study assessed the spatio-temporal variation of drought severity in the Sudano-Sahelian
region (SSR) of Nigeria, which is highly vulnerable to drought. The study analysed spatio-temporal variation of drought severity
in the region between 1961 and 2006 using the Standardized Precipitation Index (SPI) and Principal Component Analysis (PCA).
It was established that most of the extreme droughts of the highest magnitude were recorded around the 1970s and 1990s and
that there were indications that this would continue in the future. Results also identified sub-regions characterized by a
different level of drought risks in the region. The study concluded by making appropriate policy recommendations for effective
water management for the region.

Dami, A, Adesina F, Garba S.  2011.  Adaptation Strategies to Environmental Change in the Nigeria’s Section of the Chad Basin, 2011/08/31. 3 Abstract

The environmental change manifested in terms of drought and desertification in the Lake Chad basin area is characterised by the drastically reduction in the volume of the water in the basin, with serious consequences both at the local and global environment. This therefore demands an immediate attention as such change can no longer sustain the livelihood of the people of the area. A questionnaire was administered to collect primary data on the socio-economic activities and drought coping strategies of the people living in the locations of the Lake Chad basin (the Baga in the north of the basin and Southern Chad project around Marte in the south of the basin). Five communities were randomly selected from the 21 in Baga and another 5 from the 24 in Marte. The populations of these communities were between 2000 and 2500. Thus a sample size of about 2.5 %, (that is 500 people) was taken. The strategies with which local communities are responding to the increasingly unfavourable environment of the basin were evaluated. These were done with a view to providing an understanding of the dynamics of land and water uses in the area.

Momodu, A, Siyanbola W, Pelemo D, Obioh I, Adesina F.  2011.  Carbon flow pattern in the forest zones of Nigeria as influenced by land use change, 2011/01/01. Abstract

Forest in Nigeria plays a much wider role in the overall balance of issues affecting the country than those of climate change alone. Nigeria's tropical forest is depleting fast, due largely to uncontrolled human activities. Poverty, urbanization, population growth and insecurity are the major causes of this trend. Tracking carbon flow in these forest life zones will help account for the effect of these activities on the environment. COPATH, an acronym for Total Carbon Flow from Conversion to Agriculture, Pasture, Harvest and OTHER land-uses including construction of dams, roads, forest fires and human settlement, etc., was used for tracking carbon flow in the forest zones. From the five forest life zones, total carbon stored was estimated to be 2.55 TgC. The four activities of agriculture, harvest, pasture and bush burning were pronounced in contributions to land use changes, particularly to forest depletion. In this paper it is shown that carbon emission was highest from harvesting activity in year 2000, principally from clear-cutting activity in the lowland rainforest as against that of 1990 study, which showed agricultural activity as the major anthropogenic activity leading to carbon release into the atmosphere. Further, it is shown that the value of carbon emission is on the increase as compared to the earlier study with 1990 as the base year. During the two periods of study, it was however, observed that the relative contribution of each of the activities that are responsible for deforestation and affects carbon flow pattern in the forest zones and invariably causes carbon emission had not changed. Though a look at the fractional contribution of each of these activities in 2000 as against that of 1990 estimates shows a marked change. The study also concludes that if there is no change in the estimated deforestation rate of 2.23% per annum of the forest formations, lowland rainforest and riparian forests are likely to disappear by 2040.

xiv Siyanbola, Isola O, Hassan O, Ogundari I, Awoleye M, Adesina F, Ilori M.  2010.  R&D productivity and collaborations in selected Nigerian universities., 2010/10/20. Abstract

Research and development (R&D) is a significant component of quality higher education. This is quite understandable and appreciable because R&D, most especially in Science and Technology (S&T), has become the most enduring and effective means of improving sustainable economic growth, development and re-enforcing competitiveness in industries in a rapidly changing world. Universities are widely regarded not only as teaching establishments but also as organisations that create new knowledge and innovation through research. Many academics are of the opinion that doing research improves their teaching (Colbeck, 1998, 2002; Gamson, 1995; Stevans and Reingold, 2000; Robertson and Bond, 2001; Wenzel, 2001; Winkler, 1992a, b; Woolcock, 1997; Zamorski, 2002; in Begum, 2006). In recent times, universities often use evidence of research excellenceto employ or promote staff. The main claim of the teachers and administrators are that research activity can and does serve as an important mode of teaching and a valuable means of learning and thus research is a strong condition for teaching.R&D is one of the main thrusts of activities of western universities. The developed nations have clearly demonstrated that one of the most potent means of achieving developmental goals is effective building of capability in Research and Development. They have also demonstrated the relevance of effective collaboration to sustainable scientific and technological advancement (Boozeman and Lee, 2003). To corroborate this, Ehikhamenor (2003) opined that scientific productivity, in the form of intellectual contributions to the advancement of S&T, is a fundamental consideration in the scientific enterprise. A crucial requirement for
productivity and development in S&T is a system of communication among scientists and the dissemination of scientific information. Productive R&D is expected to lead to new product(s) development or improvement of existing product(s), new process development or improvement of existing process, patents, copyrights and publications. Scientific publication is a sign of good quality of invention and research outputs. Patents, copyrights, and funds from companies are signs that those inventions have market potentials (Carneiro, 2000; Werner and Souder, 1997; in Numprasertchai and Igel, 2005). Tangible R&D outcomes should promote the link between academia and the industry. However, many private and public organizations in Nigeria are skeptical about R&D outcomes from the universities and in many cases the needs of these organisations are not met. These invariably have further widened the gap between universities and industries (Oyebisi et al., 1996).
Many studies on research productivity and collaborations include an underlining assumption that collaborative activities increase research productivity (Duque et al., 2005). However, there is a dearth of information on the validity of this proposition in Nigeria. Are Nigerian researchers collaborating for R&D among themselves and with others outside their institutions? What factors inhibit collaboration activities of researchers? What influence do researchers’ collaborations have on their R&D productivity? These are some of the pertinent questions addressed in this study. For the survey, 457 copies of questionnaire were randomly distributed among lecturers. 274 of these were returned and found useful (60% response rate). The field respondents were from Faculties of Agriculture (30.8%), Science (38.8%) and Engineering/Technology (30.4%). In assessing R&D productivity of researchers we adopt the partial productivity approach. Researchers’ publications were used as output and the number of years spent to produce the publications as input (in this study 5 years, (2004 – 2008)). The normal count (of output), which is the most frequently used approach, is adopted. The outcome of the study indicated a positive relationship between R&D productivity and collaboration. This is in agreement with some previous studies on the subject of research productivity and collaboration (Lee and Bozeman, 2005; Landry et al., 1996; Harman, 1999; in Rijnsoever et al., 2008, Walsh and Maloney, 2003; in Duque et. al., (2005)

This paper investigates how human activities have influenced and altered land cover. It also indicates that the nature of cultural substitution of the indigenous forest species have significance for the functioning of the earth system. It therefore attempts to quantify the ecological implication of land cover change consequent upon land use. The paper integrated a topographical map of 1969 and satellite imageries from Landsat MSS 1972, and Landsat TM 1991 and 2000 with ground truthing and socio-economic surveys to assess changes in forest resource use and land cover in south-western Nigeria. The study argues that land cover modification and conversion is directly related to loss of biodiversity and has negative effect on the ecological setting and that there is need to develop more environmentally and socially equitable approaches to forest management.

The links between climate issues and sustainable development are manifold. Given these interconnections, the lack of close integration of the sustainable development and climate change literatures is puzzling; part of the reason for this lack of connectivity may be the very different research and policy traditions out of which each field developed. This paper argues that integrating climate change and sustainable development approaches, concepts and methods may have some important benefits. To demonstrate this point, we briefly discuss recent developments in both the climate change and sustainable development fields and then turn to the question of how to integrate them. The analysis suggests several conclusions of possible relevance to climate change and sustainable development research, including the need for an approach to scenario analysis that integrates across all aspects of climate change and sustainable development research, and the critical importance of alternative development paths and the assumptions about the reference case or baseline that underlie any analysis.

[ 1] There has been a paucity of information on trends in daily climate and climate extremes, especially from developing countries. We report the results of the analysis of daily temperature ( maximum and minimum) and precipitation data from 14 south and west African countries over the period 1961 - 2000. Data were subject to quality control and processing into indices of climate extremes for release to the global community. Temperature extremes show patterns consistent with warming over most of the regions analyzed, with a large proportion of stations showing statistically significant trends for all temperature indices. Over 1961 to 2000, the regionally averaged occurrence of extreme cold ( fifth percentile) days and nights has decreased by - 3.7 and - 6.0 days/decade, respectively. Over the same period, the occurrence of extreme hot (95th percentile) days and nights has increased by 8.2 and 8.6 days/decade, respectively. The average duration of warm ( cold) has increased ( decreased) by 2.4 (0.5) days/decade and warm spells. Overall, it appears that the hot tails of the distributions of daily maximum temperature have changed more than the cold tails; for minimum temperatures, hot tails show greater changes in the NW of the region, while cold tails have changed more in the SE and east. The diurnal temperature range (DTR) does not exhibit a consistent trend across the region, with many neighboring stations showing opposite trends. However, the DTR shows consistent increases in a zone across Namibia, Botswana, Zambia, and Mozambique, coinciding with more rapid increases in maximum temperature than minimum temperature extremes. Most precipitation indices do not exhibit consistent or statistically significant trends across the region. Regionally averaged total precipitation has decreased but is not statistically significant. At the same time, there has been a statistically significant increase in regionally averaged daily rainfall intensity and dry spell duration. While the majority of stations also show increasing trends for these two indices, only a few of these are statistically significant. There are increasing trends in regionally averaged rainfall on extreme precipitation days and in maximum annual 5-day and 1-day rainfall, but only trends for the latter are statistically significant.
