Abstract

The ecosystems present a great diversity worldwide and use various functionalities according to ecologic regions. In this new context of variability and climatic changes, these ecosystems undergo notable modifications amplified by domestic uses of which it was subjected to. Indeed the ecosystems render diverse services to humanity from their composition and structure but the tolerable levels are unknown. The preservation of these ecosystemic services needs a clear understanding of their complexity. The role of the research is not only to characterise the ecosystems but also to clearly define the tolerable usage levels. Their characterisation proves to be important not only for the local populations that use it but also for the conservation of biodiversity. Hence, the measurement, management and protection of ecosystems need innovative and diverse methods. For all these reasons, the aim of this book is to bring out a general view on the biogeochemical cycles, the ecological imprints, the mathematical models and theories applicable to many situations.

Abstract

This book - Biodiversity Enrichment in a Diverse World - considered biodiversity (plants, animals, fungi, and microbes) from three different angles: genetics, species, and ecosystems. The relationships between them are complex and it looks at these aspects from different angles and also various interventions at different levels. The scientific approach of the book demonstrates that the three levels are closely inter-connected and action is therefore needed to conserve and protect the systems if the benefits provided to human life will continue to be available. However, conservation of the biological diversity is essentially an umbrella term for traditional species, relationship to human health, ecosystem conservation and the need to manage the human use of the species and ecosystems in a sustainable way.

Abstract

Agroforestry has great potential for reducing deforestation and forest degradation, providing rural livelihoods and habitats for species outside formally protected land, and alleviating resource-use pressure on conservation areas. However, widespread adoption of agroforestry innovations is still constrained by a myriad of factors including design features of candidate agroforestry innovations, perceived needs, policies, availability and distribution of factors of production, and perception of risks. Understanding the science, and factors that regulate the adoption, of agroforestry and how they impact the implementation of agroforestry is vitally important. Agroforestry for Biodiversity and Ecosystem Services: Science and Practice examines design features and management practices of some agroforestry practices and their impact on biodiversity and the ecosystem services it delivers. It also identifies policy issues for facilitating adoption of desirable agroforestry practices and gradual diminution of undesirable policies.

Abstract

MENA is one of the richest regions in the world in terms of natural resources: it holds more than 60 percent of the world's proven oil reserves, mostly located in the Gulf region, and nearly half of gas reserves. Oil represents 80-85 percent of merchandise exports in the region, making it highly depending on fluctuations in international prices. A long strand of economic literature has suggested that such dependence may hurt a country's growth prospects and the scope for job creation by reducing economic diversification. This volume investigates the effect of natural resources and the role of

Abstract

Limited diversification is an underlying characteristic of many low-income countries (LICs). Concentration in sectors with limited scope for increases in productivity and quality may result in less broad-based and sustainable growth. Moreover, lack of diversification may increase exposure to adverse external shocks and macroeconomic instability. The SDN will have three objectives. First, to review and extend the evidence, from the existing literature and ongoing IMF work, that points to diversification as a crucial aspect of the development process. A major focus will be on cross-country and cross-regional differences in the pace of diversification. Second, to draw lessons from the experiences of those countries that have successfully diversified their economies. Third, to analyze the relationship between diversification, growth, and volatility.

Abstract

While climate change is likely to increase weather risks in many developing countries, there is little evidence on effective policies to facilitate adaptation. This paper presents experimental evidence on a program in rural Nicaragua aimed at improving households' risk-management through income diversification. The intervention targeted agricultural households exposed to weather shocks related to changes in rainfall and temperature patterns. It combined a conditional cash transfer with vocational training or a productive investment grant. The authors identify the relative impact of each complementary package based on randomized assignment, and analyze how impacts vary by exposure to exogenous drought shocks. The results show that both complementary interventions provide full protection against drought shocks two years after the end of the intervention. Households that received the productive investment grant also had higher average consumption levels. The complementary interventions led to diversification of economic activities and better protection from shocks compared to beneficiaries of the basic conditional cash transfer and control households. These results show that combining safety nets with productive interventions can help households manage future weather risks and promote longer-term program impacts.
