The Economic Impact of Climate Change on Kenyan Crop Agriculture: A Ricardian Approach by Jane Kabubo-Mariara Pdf

Abstract: This paper measures the economic impact of climate on crops in Kenya. The analysis is based on cross-sectional climate, hydrological, soil, and household level data for a sample of 816 households, and uses a seasonal Ricardian model. Estimated marginal impacts of climate variables suggest that global warming is harmful for agricultural productivity and that changes in temperature are much more important than changes in precipitation. This result is confirmed by the predicted impact of various climate change scenarios on agriculture. The results further confirm that the temperature component of global warming is much more important than precipitation. The authors analyze farmers' perceptions of climate variations and their adaptation to these, and also constraints on adaptation mechanisms. The results suggest that farmers in Kenya are aware of short-term climate change, that most of them have noticed an increase in temperatures, and that some have taken adaptive measures.

The Economic Impact of Climate Change on Agriculture in Cameroon by Ernest L. Molua,Cornelius M. Lambi Pdf

This study examines the impact of climate change on crop farming in Cameroon. The country's economy is predominantly agrarian and agriculture and the exploitation of natural resources remain the driving force for the country's economic development. Fluctuations in national income are due not merely to the decline in world demand for Cameroon's traditional agricultural exports or to mistakes in economic policy making, but also to the vagaries of the weather. Based on a farm-level survey of more than 800 farms, the study employs a Ricardian cross-sectional approach to measure the relationship between climate and the net revenue from crops. Net revenue is regressed on climate, water flow, soil, and economic variables. Further, uniform scenarios assume that only one aspect of climate changes and the change is uniform across the whole country. The analysis finds that net revenues fall as precipitation decreases or temperatures increase across all the surveyed farms. The study reaffirms that agriculture in Cameroon is often limited by seasonality and the availability of moisture. Although other physical factors, such as soil and relief, have an important influence on agriculture, climate remains the dominant influence on the variety of crops cultivated and the types of agriculture practiced.

From climate risk to resilience: Unpacking the economic impacts of climate change in Kenya by Detelinova, Iva,Thomas, Timothy S.,Hammond, Wole,Arndt, Channing,Hartley, Faaiqa Pdf

Substantial model variability exists regarding the likely meteorological impact of climate change on Kenya, particularly with respect to future precipitation levels. Significant regional differences are expected, largely due to Kenya’s diverse climate profile. Overall, temperatures are projected to increase while future precipitation levels are highly uncertain. Climate change is expected to significantly affect coastal areas, including because of sea level rise risks, stronger winds, and an overall warmer and drier climate. This will likely harm important ecosystems, including wetlands, mangroves, and coral reefs. Some models project that arid and semi-arid areas may become drier and hotter, which would exacerbate preexisting water scarcity and agricultural challenges for the already vulnerable communities living there. That said, these projections are not corroborated by all models. The climate change impact on other areas, particularly south and west of Mount Kenya, could generally be positive, as it would provide even better conditions for agriculture. The key climate change risk for Kenya is from extreme events, in particular droughts and floods. The frequency and intensity of such events is likely to increase because of climate change. They also often lead to adverse knock-on effects, such as soil erosion, land degradation, and pest breakouts. Overall, Kenya’s updated Nationally Determined Contribution (NDC) (2020) estimates that between 2010 and 2020, adverse climate change-related events led to annual socioeconomic losses of 3–5 percent of total gross domestic product (GDP).

Measuring the Economic Impact of Climate Change on Ethiopian Agriculture: by Temesgen Tadesse Deressa Pdf

Abstract: This study uses the Ricardian approach to analyze the impact of climate change on Ethiopian agriculture and to describe farmer adaptations to varying environmental factors. The study analyzes data from 11 of the country's 18 agro-ecological zones, representing more than 74 percent of the country, and survey of 1,000 farmers from 50 districts. Regressing of net revenue on climate, household, and soil variables show that these variables have a significant impact on the farmers' net revenue per hectare. The study carries out a marginal impact analysis of increasing temperature and changing precipitation across the four seasons. In addition, it examines the impact of uniform climate scenarios on farmers' net revenue per hectare. Additionally, it analyzes the net revenue impact of predicted climate scenarios from three models for the years 2050 and 2100. In general, the results indicate that increasing temperature and decreasing precipitation are both damaging to Ethiopian agriculture. Although the analysis did not incorporate the carbon fertilization effect, the role of technology, or the change in prices for the future, significant information for policy-making can be extracted.

Climate Change and Agriculture in Africa by Ariel Dinar,Rashid Hassan,Robert Mendelsohn,James Benhin,et al Pdf

'This is a well researched, thorough and impressive work on climate change and agriculture in Africa. I recommend it to students, researchers and practitioners working on climate change issues' Jabavu Clifford Nkomo, senior programme specialist, IDRC This landmark book encompasses a comprehensive assessment of the potential economic impacts of future climate change, and the value of adaptation measures in Africa for different zones, regions, countries and farm types. Researchers developed and applied multiple analytical procedures to assess quantitatively how climate affects current agricultural systems in Africa, enabling them to predict how these systems may be affected in the future by climate change under various global warming scenarios, and suggesting what role adaptation could play. The study is the first to combine spatially referenced household survey data with climatic data at both national and international levels. This book provides vital knowledge about the impacts of climate change on Africa, serving as a guide to policy intervention strategies and investment in adaptation measures. It makes a major contribution to the analysis of climate change impacts and developing adaptation strategies, especially in the highly vulnerable farming communities in the developing world.

West African Agriculture and Climate Change by Abdulai Jalloh,Gerald C. Nelson,Timothy S. Thomas,Robert Bellarmin Zougmoré,Harold Roy-Macauley Pdf

The first of three books in IFPRI's climate change in Africa series, West African Agriculture and Climate Change: A Comprehensive Analysis examines the food security threats facing 11 of the countries that make up West Africa -- Benin, Burkina Faso, Côte d'Ivoire, Ghana, Guinea, Liberia, Niger, Nigeria, Senegal, Sierra Leone, and Togo -- and explores how climate change will increase the efforts needed to achieve sustainable food security throughout the region. West Africa's population is expected to grow at least through mid-century. The region will also see income growth. Both will put increased pressure on the natural resources needed to produce food, and climate change makes the challenges greater. West Africa is already experiencing rising temperatures, shifting precipitation patterns, and increasing extreme events. Without attention to adaptation, the poor will suffer. Through the use of hundreds of scenario maps, models, figures, and detailed analysis, the editors and contributors of West African Agriculture and Climate Change present plausible future scenarios that combine economic and biophysical characteristics to explore the possible consequences for agriculture, food security, and resources management to 2050. They also offer recommendations to national governments and regional economic agencies already dealing with the vulnerabilities of climate change and deviations in environment. Decisionmakers and researchers will find West African Agriculture and Climate Change a vital tool for shaping policy and studying the various and likely consequences of climate change.

Agricultural Adaptation to Climate Change in Africa by Cyndi Spindell Berck,Peter Berck,Salvatore Di Falco Pdf

A changing climate is likely to have a drastic impact on crop yields in Africa. The purpose of this book is to document the effects of climate change on agriculture in Africa and to discuss strategies for adaptation to hotter weather and less predictable rainfall. These strategies include promoting opportunities for farmers to adopt technologies that produce optimal results in terms of crop yield and income under local agro-ecological and socioeconomic conditions. The focus is on sub-Saharan Africa, an area that is already affected by changing patterns of heat and rainfall. Because of the high prevalence of subsistence farming, food insecurity, and extreme poverty in this region, there is a great need for practical adaptation strategies. The book includes empirical research in Ethiopia, Kenya, South Africa, Tanzania, and other Sub-Saharan countries, and the conclusion summarizes policy-relevant findings from the chapters. It is aimed at advanced students, researchers, extension and development practitioners, and officials of government agencies, NGOs, and funding agencies. It also will provide supplementary reading for courses in environment and development and in agricultural economics.

The Impact of Climate Change on African Agriculture by David Maddison Pdf

This paper uses the Ricardian approach to examine how farmers in 11 countries in Africa have adapted to existing climatic conditions. It then estimates the effects of predicted changes in climate while accounting for whatever farmer adaptation might occur. This study differs from earlier ones by using farmers' own perceptions of the value of their land. Previous research, by contrast, has relied on either observed sale prices or net revenues, sometimes aggregated over geographically large tracts of terrain. The study also makes use of high resolution data describing soil quality and runoff. Furthermore, it tackles the challenges involved in modeling the effect of climate on agriculture in a study that includes countries in the northern and southern hemispheres, as well as the tropics. The study confirms that African agriculture is particularly vulnerable to climate change. Even with perfect adaptation, regional climate change by 2050 is predicted to entail production losses of 19.9 percent for Burkina Faso and 30.5 percent for Niger. By contrast, countries such as Ethiopia and South Africa are hardly affected at all, suffering productivity losses of only 1.3 percent and 3 percent, respectively. The study also confirms the importance of water supplies as measured by runoff, which, being affected by both temperature and precipitation, may itself be highly sensitive to climate change.

A review of Kenya’s national policies relevant to climate change adaptation and mitigation by Paul O Ongugo,David Langat,Vincent O Oeba,James M Kimondo,Benjamin Owuor,Jane Njuguna,George Okwaro,Aaron JM Russell Pdf

Climate change will impact many sectors of the economy: rural agriculture, biodiversity, hydrology, etc. Farmers are particularly affected since agriculture, livestock, fisheries, horticulture and agroforestry depend on specific soil, rainfall and temperature conditions. Mt. Elgon’s ecosystem is well known for its agricultural production hence our choice to study how the implementation of environmental policies affect the livelihoods of local communities.

Managing a Changing Climate in Africa by Pius Z. Yanda,Chipo Plaxedes Mubaya Pdf

There is sufficient evidence to support the fact that climate change is occurring and that this is set to accelerate. While some scholars argue that climate change is largely due to natural changes, others postulate that anthropogenic factors are the major cause. Climate change associated with increasing levels of carbon dioxide is likely to affect developed and developing countries differentially, with major vulnerabilities occurring in low-latitude regions. This book presents research findings and case studies with the endeavour to inform policies geared towards addressing problems emanating from these changes. Climate variability raises concerns over the future of agriculture, conditions of land and water availability. Therefore, climate change amplifies many economic and social risks, as well as deterioration of the environment. At the same time, non-climatic risk factors such as economic instability, trade liberalization, conflicts and poor governance all inflict upon vulnerable communities. Key discussions in this title rest on: Climate Change in Africa: its impact on rural communities, vulnerability and adaptation to climate change, financial requirements of reducing green house gases, technological transfer and natural resources; Case Studies of Vulnerability to Climate Change and Variability in Eastern and Southern Africa: experiences of impacts and adaptation to extreme events, concrete experiences from farmers and crop production adaptation; and Challenges and Opportunities to Climate Change Adaptation: factors that influence choice of response strategies, challenges and opportunities for ecosystem-based approaches; and challenges and opportunities from the use of bio-fuels as a mitigation measure to climate change.
