Abstract

Agriculture is certainly the most important food supplier while it globally accounts for more than 70% of water used and contributes significantly to water pollution. Irrigated agriculture is facing rising competition worldwide for access to reliable, low cost, and high-quality water resources. However, irrigation as the major tool and determinant of affecting agricultural productivity and environmental resources plays a critical role in food security and environment sustainability. Innovative irrigation technologies and practices may enhance agricultural water efficiency and production, in the meantime decrease the water demand and quality issues. I am very pleased to invite you to submit manuscripts in agricultural irrigation which assess current challenges and offer improvement approaches and opportunities for future irrigation.

Abstract

This book reports on long-term comparative organic farming systems' research trials carried out over the last 5 years in the Southern Cape of South Africa, as well as research into the successes and failures of the organic sector and the technical tools required for sustainable development in South Africa, Zambia, Uganda and Tanzania. It includes 24 chapters organized into 4 parts. Part 1 (Chapters 1-6) discusses the historical development of organic farming systems, examines the global issues which confront us, and develops some concepts showing a progression in small-scale farmer development and how this can be supported with appropriate training and policy. The difference between national food self-sufficiency and household food security is examined, and the organic sector is introduced. Part 2 (Chapters 7-14) deals with capacity building and climate change. Holistic systems, inclusive participatory approaches, institution building and experiential learning are examined. Organic food production, farmer training, value chains, impact of drought on food prices and food availability, and urban water and energy use efficiency are described. Part 3 (Chapters 15-22) presents evidence on how to support organic farmers. It starts with 2 case studies on the well-developed organic sector in Uganda and the developing one in Zambia. The following chapters discuss soil carbon determination, comparison of organic and conventional farming systems, pest and disease control (e.g., chemical, holistic and biological control), soil fumigation, soil microbiology in organic and conventional systems, soil fertility changes and crop yield. Part 4 (Chapters 23-24) makes strategic suggestions about how to upscale organic farming and organic food systems in Southern Africa. This book is a vital resource for all stakeholders in organic agriculture.

Abstract

As sessile organisms, plants have to cope with a multitude of natural and anthropogenic forms of stress in their environment. Due to their longevity, this is of particular significance for trees. As a consequence, trees develop an orchestra of resilience and resistance mechanisms to biotic and abiotic stresses in order to support their growth and development in a constantly changing atmospheric and pedospheric environment. The objective of this Special Issue of Forests is to summarize state-of-art knowledge and report the current progress on the processes that determine the resilience and resistance of trees from different zonobiomes as well as all forms of biotic and abiotic stress from the molecular to the whole tree level.

Abstract

Global crop production must substantially increase to meet the needs of a rapidly growing population. This is constrained by the availability of nutrients, water, and land. There is also an urgent need to reduce the negative environmental impacts of crop production. Collectively, these issues represent one of the greatest challenges of the twenty-first century. Sustainable cropping systems based on ecological principles are the core of integrated approaches to solve this critical challenge. This special issue provides an international basis for revealing the underlying mechanisms of sustainable cropping systems to drive agronomic innovations. It includes review and original research articles that report novel scientific findings on improvement in cropping systems related to crop yields and their resistance to biotic and abiotic stressors, resource use efficiency, environmental impact, sustainability, and ecosystem services.
