Strategies for Sustainable Land Management in the East African Highlands by J. Pender,Dr. Frank Place,Simeon Ehui Pdf
Deforestation, overgrazing, and unsustainable methods of cultivation are threatening agriculture and food security in the highlands of East Africa. In response, economists and other development professionals have turned their attention to combating the pr
Integrated Natural Resource Management in the Highlands of Eastern Africa by Laura Anne German,Jeremias Mowo,Tilahun Amede,Kenneth Masuki Pdf
This book documents a decade of research, methodological innovation, and lessons learned in an eco-regional research-for-development program operating in the eastern African highlands, the African Highlands Initiative (AHI). It does this through reflections of the protagonists themselves—AHI site teams and partners applying action research to development innovation as a means to enhance the impact of their research. The book summarizes the experiences of farmers, research and development workers and policy and decision-makers who have interacted within an innovation system with the common goal of implementing an integrated approach to natural resource management (NRM) in the humid highlands. This book demonstrates the crucial importance of "approach" in shaping the outcomes of research and development, and distils lessons learned on what works, where and why. It is enriched with examples and case studies from five benchmark sites in Ethiopia, Uganda, Kenya and Tanzania, whose variability provides the reader with an in-depth knowledge of the complexities of integrated NRM in agro-ecosystems that play an important role in the rural economy of the region. It is shown that the struggle to achieve sustainable agricultural development in challenging environments is a complex one, and can only be effectively achieved through combined efforts and commitment of individuals and institutions with complementary roles.
The sustainable land management program in the Ethiopian highlands: An evaluation of its impact on crop production by Schmidt, Emily,Tadesse, Fanaye Pdf
Agricultural productivity in the highlands of Ethiopia is threatened by severe land degradation, resulting in significant reductions in agricultural GDP. In order to mitigate ongoing erosion and soil nutrient loss in the productive agricultural highlands of the country, the government of Ethiopia initiated a Sustainable Land Management Program (SLMP) targeting 209 woredas (districts) in six regions of the country. This study evaluates the impact of SLMP on the value of agricultural production in select woredas by using a panel survey from 2010 to 2014. Whereas previous studies have used cross-sectional data and short timeframe field trials to measure sustainable land management (SLM) effects on agricultural productivity, this analysis exploits data collected over four years to assess impact. The results of this analysis show that participation by farmers in SLMP, regardless of the number of years of participation in the program, is not associated with significant increases in value of production. This may be due to several reasons. First, similar to previous studies, it is possible that longer term maintenance is necessary in order to experience significant benefits. For example, Schmidt and Tadesse (2014) report that farmers must maintain SLM for a minimum of seven years to reap benefits in value of production. Second, this analysis finds that value of production, as well as SLM investments, increased significantly in both treatment and non-treatment areas over the study period. Previous research has found that non-treatment neighbors learn from nearby program areas, and adopt technologies similar to programmed areas, which would dilute the impact measurement of program effects (Bernard et al. 2007; Angelucci and DiMaro 2010). Finally, it is important to note that kebeles that were not selected in the SLMP, but are downstream relative to a targeted kebele may receive indirect benefits through reduced flooding, increased water tables, etc. Thus, the impact of the SLMP may be underestimated in this analysis if non-program kebeles are benefiting indirectly from the program.
Sustainable Poverty Reduction in Less-favoured Areas by Ruerd Ruben,J. Pender,Arie Kuyvenhoven Pdf
Less-favored areas with limited agricultural potential or difficult access conditions, support 40 percent of the world's rural population suffering from chronic poverty. While agricultural innovations and rural development programs have begun to be implemented within developing countries, they do not address the specific obstacles faced by this large population. Instead, a targeted approach is needed to identify different resource management strategies for particular types of households and communities as well as creating balanced investments aimed at sustainable intensification of rural livelihoods. Such efforts have been the focus of the research program on Regional Food Security Policies for Natural Resource Management and Sustainable Economies (RESPONSE). Through the study of less-favored areas in Africa, Latin America, and South and East Asia, development pathways allowing for the careful adjustment of resource use strategies at the field, farm-household and village level are explored.
Gender gaps in sustainable land management and implications for agricultural productivity: Evidence from Ethiopia by Kato, Edward,Mekonnen, Dawit Kelemework,Ringler, Claudia Pdf
We investigate whether a large-scale watershed program promoting sustainable land management (SLM) in Ethiopia increases adoption of SLM and its benefits on plots owned by women in male-headed households compared to plots owned by their spouses, jointly owned plots as well as plots of female headed households (FHH). The analysis is based on a survey of 500 households and 2900 plots conducted in the Abbay basin of Ethiopia where the SLM program was implemented between 2012 and 2017. Our findings show that the SLM program significantly increased adoption of SLM practices (soil bunds, stone terraces, mulching) in male-headed households but that adoption was centered on jointly owned plots and male-owned plots, with no significant adoption on women-owned plots. The results also show that women in male-headed households are more constrained to participate in SLM programs compared to their counterparts in FHH. Results further show that although FHH were less likely than male-headed households to adopt SLM in watersheds with no SLM interventions, the SLM program significantly increased adoption of soil bunds on plots in FHH. SLM adoption and impacts can likely be further strengthened if a focus on removing women’s constraints is added.

Global change and human vulnerability to vector-borne diseases by Rubén Bueno-Marí,Ricardo Jiménez-Peydró Pdf
It is well known that several climatic, environmental and socio-demographic changes that have occurred in the last years are some of the most important causes for the emergence/resurgence of vector-borne diseases worldwide. Global change can be defined as the impact of human activity on the fundamental mechanisms of biosphere functioning. Therefore, global change includes not only climate change, but also habitat transformation, water cycle modification, biodiversity loss, synanthropic incursion of alien species into new territories, or introduction of new chemicals in nature. On this respect, some of the effects of global change on vector-borne diseases can be currently evaluated. Globalization has enabled the movement of parasites, viruses and vectors among different countries, or even at intercontinental level. On this regard, it is important to note that the increase of imported malaria cases in different Southern European countries has led to the re-appearance of autochthonous cases of disease transmission. Moreover, the used tire trade, together with global warming, have facilitated the introduction, spread and establishment of potential Dengue tropical vectors, such as Aedes aegypti or Aedes albopictus in temperate areas. Consequently, recently the first Dengue indigenous cases in the last decades have been reported in different Southern areas of North America and Europe. Furthermore, habitat modification, mainly deforestation and transformation of aquatic environments, together with the changes in thermal and rainfall patterns, are two of the key factors to explain the increasing incidence of Leishmaniasis and several tick-borne diseases. The aim of this Research Topic is to cover all related fields with the binomial vector-borne diseases / global change, including basic and applied research, approaches to control measures, explanations of new theories, opinion articles, reviews, etc. To discuss these issues, a holistic and integrative point of view is necessary, which only would be achieved by the close and active participation of specialists on entomology, parasitology, virology and epidemiology. Our objective is to use a systems approach to the problem of global change and vector-borne diseases. To achieve this ambitious goal and to comply with a demand of first-rate scientific and medical interest, we are very keen on asking for the participation of multiple contributors.
Linkages Between Land Management, Land Degradation, and Poverty in Sub-Saharan Africa by Nkonya, Ephraim,Pender, John,Kaizzi, Kayuki C.,Kato, Edward,Mugarura, Samuel,Ssali, Henry,Muwonge, James Pdf
Most African countries strive for both poverty reduction and sustainable land management, yet information on the exact relationship between these goals is limited. This report seeks to fill the gap by demonstrating a strong linkage between poverty and land management. Using Uganda as a case study, the authors show that certain policies, such as investments in soil and water conservation and agroforestry, may simultaneously increase productivity and reduce poverty and land degradation. Other strategies, including development of rural roads, non-farm activities, and rural finance, may reduce poverty without significantly affecting productivity or land management. Some policies, however, will likely involve trade-offs among different goals and will need to have their negative impacts minimized. Those in government, NGOs, the private sector, or academia who are concerned about sustainably reducing poverty in Sub-Saharan Africa will benefit from this analysis of how to pursue these key development goals.

Food and Agriculture in Ethiopia by Paul Dorosh,Shahidur Rashid Pdf
The perception of Ethiopia projected in the media is often one of chronic poverty and hunger, but this bleak assessment does not accurately reflect most of the country today. Ethiopia encompasses a wide variety of agroecologies and peoples. Its agriculture sector, economy, and food security status are equally complex. In fact, since 2001 the per capita income in certain rural areas has risen by more than 50 percent, and crop yields and availability have also increased. Higher investments in roads and mobile phone technology have led to improved infrastructure and thereby greater access to markets, commodities, services, and information. In Food and Agriculture in Ethiopia: Progress and Policy Challenges, Paul Dorosh and Shahidur Rashid, along with other experts, tell the story of Ethiopia's political, economic, and agricultural transformation. The book is designed to provide empirical evidence to shed light on the complexities of agricultural and food policy in today's Ethiopia, highlight major policies and interventions of the past decade, and provide insights into building resilience to natural disasters and food crises. It examines the key issues, constraints, and opportunities that are likely to shape a food-secure future in Ethiopia, focusing on land quality, crop production, adoption of high-quality seed and fertilizer, and household income. Students, researchers, policy analysts, and decisionmakers will find this book a useful overview of Ethiopia's political, economic, and agricultural transformation as well as a resource for major food policy issues in Ethiopia.
