Buch. Zustand: Neu. Neuware - In many communities in the world, the population lives on agriculture. Smallholder agriculture covers 75% of agricultural production, most of which are rain-fed agriculture. This number indicates that the impact of population explosion in rural areas is prompting communities to adopt unsustainable farming practices, like burning of tropical rain forests to grow crops, planting on steep slopes, entering fragile marginal ecosystems, and overgrazing and over cropping. This volume estimates that one-sixth of the globe's land area (nearly 2 billion hectares) has been degraded due to overgrazing and negative farming practices. Water supply for agricultural purposes is becoming scarcer, and there is almost no land reserve that can be used to expand the agricultural base. Come 2025, nearly 3 billion people in 48 countries shall be affected by severe water shortages throughout the year or some months. The volume recommends suitable and site-specific technologies to reverse poverty and food insecurity issues. Some of the chapters mentioned include: chapter 1: philosophies of restoration agriculture on small farms, chapter 2: soil food web and chapter 3: conservation farming among others. Both scientific and indigenous knowledge available to the community should effectively facilitate this process, and farmers must actively participate in designing, implementation and evaluation of these technologies.…

Buch. Zustand: Neu. Neuware - Mountains represents one fifth of the world's land area, also about one tenth of the world's population lives there, mountains are not just for spending some nice time and lovely vacation with mother nature. Mountains can produce a large variety of crops that are not available from the plains. There are two main general challenges facing mountain agriculture that includes: Market accessibility, which is not exclusive to selling the products but also sourcing the inputs as well, as they are usually far from the community clusters. Labor availability, mountain agriculture is a family based agriculture as no one will go far to a mountain and get up it to find work, in the same time mountain agriculture faces out-migration to cities and community clusters for high education and better jobs. Mountain agriculture has big economic development potential and its contribution to food security can be easily increased by increasing its efficiency and maintaining its biodiversity, this book is addressing the real potential of mountain farming.…

Buch. Zustand: Neu. Neuware - Most countries have a variety of climates and soils to grow horticultural crops, providing sufficient opportunities for the expansion of the fruit sector, however the biggest challenge presently is to produce enough fruits to meet the needs of the growing population. This volume discusses the technologies applied for effective use of resources in order to obtain higher yield per investment unit with high-quality yields in a short time. In today's open economy era; in the domestic and international markets, quality fruit products are becoming more and more necessary to remain competitive. This is only possible through the deployment of high-tech applications and precision farming methods. Fruits are important to people and also play a crucial role in religious customs, mythology and artwork. They are not just delicious, but also contain many nutrients vital for human health. Fruit production needs a lot of scientific knowledge and basic understanding to be successful. The volume compiles various topics in fruit production technology, such as layout and planting, different cultural customs, development and reproductive traits of fruit crops, and infertility. Some of the topics discussed include chapter 1: introduction to fruit crop production, chapter 2: classification of fruits, chapter 3: importance of fruit production, and chapter 4: planting systems and transplanting of fruit trees among others.

Buch. Zustand: Neu. Neuware - Close to 77 million people lost their lives due to both world wars. Compare this with 30 million to 100 million loss of lives due to the Spanish flu epidemic. While epidemics are sudden outbreaks over one area, pandemics affect diseases across borders. According to research, epidemics not only target health but also socioeconomic systems. These factors coupled with the ongoing COVID-19 pandemic that has brought the world to a standstill several times make this book most timely. This book presents insights as to the current epidemic threats along with many diseases that are 'neglected'. A section has also been included on how healthcare providers: doctors and nurses are affected during such epidemics. Further, a chapter on the fear and stigma associated with such epidemic diseases has also been covered. This becomes relevant given and is also one of the unique aspects of the book given that the stigma associated with many diseases is more damaging than the disease.…

Buch. Zustand: Neu. Neuware - There is prestige in a well-manicured landscape. Apart from the prestige well established and maintained lawns act as green spaces that have societal, economic, health and economic benefits. This book guides the audience on some creative ideas of lawns, the grass and grass alternatives to use, and machinery to use in lawn establishment and maintenance.

Buch. Zustand: Neu. Neuware - The current alarming rate of decline of earth's natural resources, particularly of the reserves of rock phosphate and fossil fuel, is of great concern for the future of agriculture, particularly in developing countries. Not surprisingly, sustainable crop production remains a major global challenge and has drawn increasing attention among policy makers, business, and the scientific community. The agricultural use of land for crop production leads to the continuous extraction of soil nutrients. In the absence of adequate nutrient replenishment, a subsequent decrease of soil nutrient availability may occur, exerting a negative effect on yield. This book deals with strategies to overcome low nutrient availability in soils mainly rely on the use of fertilizers and crop breeding.…

Buch. Zustand: Neu. Neuware - It is essential to produce climate system models that can bring about an accurate representation of the climate forecast.

Buch. Zustand: Neu. Neuware - Water differentiates planet earth from all the other planets in the solar system. At the same time, as the global supply of freshwater is beyond enough to meet all contemporary and foreseeable water needs, its spatial and temporal allocations are not. There are numerous areas in which freshwater resources remain inadequate to fulfil domestic, socioeconomic growth and environmental needs. In such areas, the lack of clean water to satisfy human consumption and sanitation needs is indeed a limitation on human health and productivity, and for this reason on economic growth as well as on the upkeep of a clean environment and holistic ecosystems. This book mentions that researchers must discover ways to take away these constraints. There are a couple of demanding situations in doing that, in particular given an unstable and unsure future climate, plus a rapidly developing population that is driving expanded socioeconomic improvement, globalization, and urbanization. How best to fulfil these needs requires research in various areas of water management. This book identifies the problems facing water managers today, and the research required to better inform individuals who attempt to develop a more sustainable and suitable future.…
