Sustainable Livestock Farming for Zero Hunger

Sustainability in livestock farming is a highly challengeable task in the face of climate change. In a sustainable farming system, it is expected to keep the continuity in practising of farming throughout a year by introducing autonomy in management of farming system, even under adverse climatic changes or non-availability of feedstock from other sources. In sustainable farming system, the needs of one element are met by the wastes of another component. For example, animal manure builds the soil, replenishing nutrient used by crops that are fed to animals. Livestock farming can be fully autonomous by linking the farmhouse with a polyhouse or greenhouse where variety of feedstock can be developed, even unaffordable climatic conditions (Fig. 6.1). The same way independent from conventional energy, goat manure-based biogas generating system can be developed for fulfilling the energy need of a livestock farmhouse.
