Abstract:

With a population of close to 13 million, and an annual growth rate of 2.86 percent, Rwanda plans to position itself as a climate resilient, low carbon, low unemployment, reduced poverty country, with a strong services sector by 2050. Its projected increase in its urbanization rate from a current value of 18.4 percent to 35 percent by 2024 is driven by strong political will, significant investments in infrastructure, service provision, and human capital development. Rwanda’s secondary cities, identified as economic nodes of growth, are currently undergoing revision of their masterplans in consideration of climate change realities and the pressure on infrastructure and services due to rapid urbanization. Currently, cities in Rwanda do not yet have a system of public open spaces. Where available, such spaces are usually hardly accessible and need upgrading. To address this, the Ministry of Infrastructure, Rwanda Housing Authority, City of Kigali and six secondary cities have committed to deliver on public open space related activities and targets under the yearly performance contract ‘Imihigo’. The outcomes of their commitments support the climate-responsive revision of masterplans of the City of Kigali and six secondary cities. This paper presents public open space initiatives in Kigali and the results of the technical assessment of public open spaces and participatory planning and design workshop in Nyagatare, secondary city in Rwanda’s. It also discusses ongoing policy changes and initiatives that aim to promote public open spaces as crucial for urban public health.

Abstract:

This study quantifies the potential responses of 11 staple crop yields to projected changes in temperature and precipitation in Rwanda, using a cross sectional model based on yield data collected across more than 14,000 villages. We incorporated a relatively high spatial resolution dataset on crop productivity, considered a broad range of crops relevant to national agricultural production priorities, used environmental data developed specifically for Rwanda, and reported uncertainty both from our estimation model and due to uncertainty in future climate projections. We estimate that future climate change will have the largest impacts on potential productivity of maize, bush bean, and Irish potato. All three crops are likely to experience a reduction in potential yields of at least 10% under Representative Concentration Pathway (RCP) 4.5 and at least 15% under RCP 8.5 by 2050. Notably, these are important crops nationally, and three of the crops targeted by Rwanda’s Crop Intensification Program. We find that the most severe reductions in potential crop yields will occur in the drier eastern savannah and plateau regions, but that the impacts of climate change could be neutral or even positive in the highlands through mid-century. The refined spatial scale of our analysis allows us to identify potentially vulnerable regions where adaptation investments may need to be prioritized to support food security and climate resilience in Rwanda’s agricultural sector.

Abstract:

This paper had the objective of analyzing and characterizing the leachate from Nyanza landfill. The results revealed that the composition of the leachate is changeable according to the nature, the deposit time, and the climatic change. Leachate collected in the middle of landfill is categorized in the phase III of acid formation while the leachate collected from the exit is classified in the phase IV of methane formation and reasons for this variability are mainly waste nature, the deposit time, and the climate changes.

Abstract:

The changing climate poses a great challenge to many wetlands productivity worldwide. Rice production in wetlands is a major source of livelihood in developing countries such as Rwanda. This study aimed at determining the factors influencing adaptation methods when farmers perceive the changing climate at Bugarama Wetland Rice Scheme in Rwanda. A descriptive research design was used by this study, whereby quantitative and qualitative data was collected. The analysis was based on data collected from 300 selected farmers using systematic random sampling method. We employed descriptive statistics to assess how farmers perceive the effects of climate change and descriptively measured the new adaptation methods used by farmers in Bugarama to increase their yields. The study adopted Heckman two-step model to determine factors that influence adaptation choices, this analysis procedurally required farmers’ knowledge of perception that makes them respond to the effects of changes in climatic conditions by the use of new adaptation methods. The results deduced that level of education (p =0.019), extension access (p=0.001), market distance (p=0.002) and rice income (p < 0.001) had a probability of influencing farmers perceptions about climate change thus need to adapt. Based on the outcome model, results showed that extension access (p < 0.001), household size (p= 0.098), market distance (p= 0.047), rice income (p =0.032), farmers-to-farmers contact (p < 0.001) and effects of climate change on rice (p=0.038) had a greater probability of influencing farmers choice of adaptation method used to improve rice yields. To conclude, the study found that access to informational facilities and rice income, influenced farmers’ perceptions while extension access, rice income, market distance, farmers-to-farmers contact and effects of climate change on rice yield strongly had a probability of determining farmers’ choice of adaptation. This study recommends that the Rwandan government and local administrators need to develop a strategy that would allow farmers to access information facilities about new technology so as to adapt to the effects of climate change thus improve their rice yields.

Abstract:

In recent decades, population growth and economic development have greatly influenced the pattern of land use/land cover (LULC) in Rwanda. Nevertheless, LULC patterns and their underlying change mechanisms under future climate conditions are not well known. Therefore, it is particularly important to explore the direction of LULC transfer in the study area, identify the factors driving the transfer of different types of LULC and their changes, and simulate future LULC patterns under future climate conditions. Based on LULC analyses of Rwanda in 1990, 2000, 2010, and 2015, the LULC pattern of Rwanda in the next 30 years was simulated using an LULC transition matrix, random forest sampling, the Markov chain model, and the PLUS model. The results showed that LULC change in the study area primarily comprised a decrease in forest area and expansion of cropland area, accompanied by a small increase in grassland area and an annual increase in urban land area. Prior to 2000, the LULC in Rwanda was mainly converted from forest and grassland to cropland, with the ratio being 0.72:0.28. After 2010, the LULC was mainly converted from forest to grassland and cropland, with the ratio being 0.83:0.17. Changes in forests, grasslands, and cropland are driven by multiple factors, whereas changes in wetlands, water, urban land, and unused land are more likely to be driven by a single factor. The existing trend of LULC change will continue for the next 30 years, and the future LULC pattern will exhibit a trend in which cropland area will increase in the west and grassland area will decrease, whereas grassland area will increase in the east and cropland area will decrease.

Abstract:

Abstract. Air pollution is understudied in sub-Saharan Africa, resulting in a gap in the scientific understanding of emissions, atmospheric processes, and impacts of air pollutants in this region. The Rwanda Climate Observatory, a joint partnership between MIT and the government of Rwanda, has been measuring ambient concentrations of key long-lived greenhouse gases and the short-lived climate-forcing pollutants CO2, CO, CH4, black carbon (BC), and O3 with state-of-the-art instruments on the summit of Mt. Mugogo (1.586∘ S, 29.566∘ E; 2590 m above sea level) since May 2015. Rwanda is a small, mountainous, and densely populated country in equatorial East Africa, currently undergoing rapid development but still at less than 20 % urbanization. Black carbon concentrations during Rwanda's two dry seasons (December–January–February, DJF, and June–July–August, JJA), which coincide with the two regional biomass burning seasons, are higher at Mt. Mugogo than in major European cities with daily values (24 h) during the dry season of around 5 µg m−3 (daily average concentrations ranging from less than 0.1 to over 17 µg m−3 for the entire measurement period). BC baseline concentrations during biomass burning seasons are loosely correlated with fire radiative power data for the region acquired with a MODIS satellite instrument. The position and meteorology of Rwanda is such that the emissions transported from both the northern and southern African biomass burning seasons affect BC, CO, and O3 concentrations in Rwanda. Spectral aerosol absorption measured with a dual-spot Aethalometer varies seasonally due to changes in types of fuel burned and the direction of pollution transport to the site. Ozone concentrations peaked during Rwanda's dry seasons (daily measured maximum of 70 ppbv). The understanding and quantification of the percent contributions of regional and local (beyond large-scale biomass) emissions is essential to guide policy in the region. During the rainy seasons, local emitting activities (e.g., cooking, transportation, trash burning) remain steady, regional biomass burning is low, and transport distances are shorter as rainout of pollution occurs regularly. Thus, local pollution at Mugogo can be estimated during this time period and was found to account for up to 35 % of annual average BC measured. Our measurements indicate that air pollution is a current and growing problem in equatorial East Africa.

Abstract:

Climate change causes loss on lives and livelihoods while regular update strengthens resilience. This study aimed to analyze the rainfall variability impact on livelihoods in Northern Rwanda. The data on community losses due to rainfall variability were considered from 2013 to 2019. The GIS and SPSS helped the data analysis process. The results showed high mean monthly rainfall (119.345 and 90.05 mm) in 2013 and 2017, respectively. This caused landslide, flood, rainstorms, windstorms, lightning, and hailstorms occurrence, which killed/injured people, damaged houses and cropland, livestock loss, and destruction of infrastructures. The correlation analysis indicated a statistically significant p-value of 0.0151 lower than 0.05 and approved that rainfall variability negatively impacts livelihoods. This study can enable policymakers to better understand how changes in rainfall impact livelihoods and strategic measures to adopt for climate variability and climate change adaptation.

Abstract:

Climate adaptive strategies seek to minimize harms of climate change. Scholarly research has yet to examine the impact of these strategies in post-conflict communities, especially with regard to whether they might contribute to fostering greater overall well-being, or positive peace. This thesis seeks to address this gap and adopts the research question, how does climate adaptation impact positive peace in post-natural resource conflict communities? I hypothesize that climate adaptation is likely to contribute to positive peace in post-natural resource conflict communities by reducing environmental stressors through strengthened natural resource management. Theoretically, climate adaptation provides the capacity for local communities to strengthen natural resource management, which enables them to cope with the effects of climate change. This in turn, reduces environmental stressors and allows communities to better meet local needs and foster positive peace. Using a qualitative method of structured focused comparison, I collect empirics from two districts in post-natural resource conflict Rwanda (after 2002) to test how climate adaptation impacts positive peace at the local level. Although findings show little evidence that climate adaptation drives positive peace, results indicate that such programs may be poised to contribute to lessened environmental stress through strengthened natural resource management.

Abstract:

Sub-Saharan Africa is today facing a big challenge regarding food deficiency and water scarcity due to climate change. One of these countries is Rwanda, a small landlocked country in the middle of Africa. Rwanda strongly depend on agriculture, both in the aspect of reducing poverty and hunger but also because their economy security depend on it. Because of increasingly fluctuating rainfalls their agriculture becomes more dependent on irrigation and the availability to water resources. To investigate how the climate change will affect the amount of water resources in the coming decades, this study is focusing on the watershed and marshland of Muvumba P8 in Nyagatare, Rwanda. A hydrological model was created, in a software called Soil and Water Assessment Tool (SWAT), with soil, land use and slope maps for the watershed. Calibrating the model was done with help of Climate Forecast System Reanalysis (CFSR) data and run for nine different climate model datasets. An uncertainty had to be taken into account regarding both the measured local data and the downloaded data. To be able to compare the amount of water resources and the irrigation requirements for the rice crop the farmers were growing on the marshland, the crop water requirements for rice was estimated with FAO’s program called CROPWAT. The irrigation system on the marshland allows a double cropping of rice every year and consist of a system depending on elevation differences to create natural fall. There was three reservoirs along the marshland but to limit the project, only the first reservoir was taken into account. This was complemented with existing data and field survey. Six out of nine climate models showed a decrease in median discharge over the coming 30 years compared to the CFSR historical median discharge. This means that less water in general will reach the outlet of the watershed in the years to come. At the same time all climate models indicate an increase in irrigation requirements for the rice crops. The seasons are probably going to change, a longer and drier season between June and August and a rainier season between September and November are projected.

Abstract:

Il cambiamento climatico è una sfida chiave dei nostri tempi, soprattutto per i paesi in via di sviluppo, che basano i loro processi di crescita sull'utilizzo delle risorse naturali e sul settore agricolo. Sebbene esistano varie strategie e piani, sia a livello pubblico che privato, per far fronte agli impatti dei cambiamenti climatici, l'implementazione delle misure di adattamento è ancora limitata. Questo è collegato alla presenza d'incertezza riguardo agli impatti dei cambiamenti climatici in futuro. Pertanto, nuovi strumenti e processi decisionali dovrebbero essere valutati e diffusi nel tentativo di aiutare i decisori pubblici e privati nella definizione e attuazione di misure concrete di adattamento. In questa tesi, la Portfolio Analysis viene applicata alla valutazione di investimenti agricoli in Ruanda
Climate change is a key challenge of our times, especially for developing countries, which significantly rely on natural resources and on the agriculture sector. Even though there are various strategies and plans to face climate change impacts, the implementation of adaptation measures is still uneven. This is connected to the presence of uncertainty about the impacts of climate change in the future. Therefore, new decision-making tools and decision processes should be assessed and disseminated in the attempt to help the decision makers in the definition and implementation of concrete adaptation measures. In this dissertation, the Portfolio Analysis methodology is applied in the evaluation of agricultural investments in Rwanda

Abstract:

PhD. (Environmental Management)
Climate change and variability has rapidly emerged as one of the most serious threats to sustainable development especially for developing African countries such as Rwanda. Since most of the agricultural activities in African countries are rain-fed, any adverse change in climate is likely to have a devastating effect on output and the livelihood of the majority of the population in the affected countries. Therefore, there should be continuous and regular preparedness to on-going climate variability. Climate change and variability derived information, are most likely to improve the agricultural outcomes when it is integrated into a framework for decision making to mitigate specific risks. It is in that regard, this research aims at analyzing climate change and variability and their impacts on the yields of major food crops in Rwanda. The raw climatic data (temperatures and precipitations) used in this study were obtained from the Rwandan Meteorological Center based in Kigali and Rwanda Environment Management Authority (REMA) while the agricultural records were collected from the National Institute of Statistics of Rwanda (NISR) and the Ministry of Agriculture and Animal Resources (MINAGRI). Length and completeness of records were the basic criteria used to select weather stations in order to have the most complete dataset. Five major crops, namely beans, cassava, Irish potatoes, maize, and sweet potatoes were selected for investigation because they are grown over large areas in most parts of the country during the two agricultural seasons i.e. season A (September-January) and season B (February-June). This research uses a number of statistical techniques in an attempt to quantify the magnitude and significance in temperature, rainfall, number of rainy days, aridity index and rainfall erosivity changes and variability taking place over Rwanda. The same techniques were applied in determining the magnitude and significance of inter-annual variations in food crop yields over Rwanda. A geographical information system (GIS) was used to present spatially the results on maps...

Abstract:

The disappearance of Rwanda’s forests and attendant change in climatic conditions prompted the government to explore clean energy alternatives such as biogas. Unlike at any other time in Rwanda’s history, more and more Rwandans in rural areas are becoming owners of cattle because of the Government of Rwanda’s agricultural direct assistance and poverty reduction programme known as Girinka. This chapter focuses on the various strategies employed by the government of Rwanda in achieving increased biogas use among the rural poor Girinka beneficiaries who use cow dung for their domestic biogas plants. Conditions necessary for successful implementation of clean energy pro-poor reforms in rural communities are explored.

Abstract:

Land expansion to increase agricultural production in East Africa (Burundi, Ethiopia, Kenya, Rwanda, Tanzania and Uganda) will be limited by climate change. In this study, we predict landscape suitability for chickpea (Cicer arietinum), common bean (Phaseolus vulgaris), lentil (Lens culinaris), field pea (Pisum sativum) and pigeon pea (Cajanus cajan) cultivated across diverse agro-ecological zones (AEZs) in East Africa from 1970 to 2070, under the 4.5 emission scenario. Our aim was to understand how suitability shifts among the AEZs might affect the agricultural potential of the selected crops. We use the geolocations of each crop together with response curves from the species distribution software, Maxent to fine-tune the expert based EcoCrop model to the prevailing climatic conditions in the study region. Our optimal precipitation and temperature ranges compared reasonably with the FAO base parameters, deviating by ±200mm and ±5oC, respectively. There is currently a high potential for lentil, pea and common bean in the region. However, under future climates, the suitability of common bean and lentil with a much narrow climate range will shrink considerably while pigeon pea and chickpea will continue to be suitable. Under projected climatic conditions, the agricultural potential of these legumes will be limited by drought or heat stress as landscape suitability will shift optimally toward the cool sub-humid (tcsh), and the cool semi-arid (tcsa) zones. Tanzania, Kenya and Uganda will be the most affected and will lose a large share of suitable arable land. Different adaptation measures will be needed to increase the agricultural potential and optimized production in vulnerable AEZs. In general, smallholder farmers will have to substitute lentil and common bean for chickpea and pigeon pea or other suitable substitutes to address food security issues. Notwithstanding the limitations of this study, our results highlight the vulnerability of legumes crops as well as their production zones which could be useful in the formulation of adaptation strategies for the East African region.

Abstract:

This rapid review synthesises evidence on FCDO climate projects across the East African region in the following countries; Kenya, Rwanda, Uganda and Tanzania. This review established that sector stakeholders in countries like Rwanda lacked climate impact information. This highlights the need of providing the right information in the right form to meet the end users need. The above case studies have shown the need for consistent and harmonised future climate projections that are country specific. According to a study undertaken in Tanzania and Malawi, understanding the likely future characteristics of climate risk is a key component of adaptation and climate-resilient planning, but given future uncertainty it is important to design approaches that are strongly informed by local considerations and robust to uncertainty. According to the findings from the research, policy incoherence, over-reliance on donor funding, change in leadership roles is a barrier to adaptation. There is also an urgent need for mechanisms for sharing experience and learning from methodologies, technologies, and challenges. Further, Stakeholder dialogue and iterative climate service processes need to be facilitated. This review also explores approaches to communicating climatic uncertainties with decision-makers. Particularly, presentation of data using slide-sets, and stories about possible futures.
