Irrigation in viticultureIrrigation in viticulture is the process of applying extra water in the cultivation of grapevines. It is considered both controversial and essential to wine production. In the physiology of the grapevine, the amount of available water affects photosynthesis and hence growth, as well as the development of grape berries. While climate and humidity play important roles, a typical grape vine needs 25-35 inches (635-890 millimeters) of water a year, occurring during the spring and summer months of the growing season, to avoid stress.
Betsileo peopleThe Betsileo are a highland ethnic group of Madagascar, the third largest in terms of population. They chose their name, meaning "The Many Invincible Ones", after a failed invasion by King Ramitraho of the Menabe kingdom in the early 19th century. The Betsileo occupy the south of the Madagascar plateau. Their traditional territory extends from the north of the Mania River in the north to the foot of the Andringitra Massif in the south; to the west by the Bongolava chain and the east by the Eastern Forest, occupied by the Tanala tribe.
Sustainable yieldThe sustainable yield is a form of sustainability that refers to the maximum harvest that does not deplete or over-harvest where the renewable resource can not grow back. In the simplest terms, sustainable yield is the largest amount of resource that humans can take or use without causing damage or allowing for a decline to happen in the specific population. In more formal terms, the sustainable yield of natural capital is the ecological yield that can be extracted without reducing the base of capital itself, i.
Poverty reductionPoverty reduction, poverty relief, or poverty alleviation is a set of measures, both economic and humanitarian, that are intended to permanently lift people out of poverty. Measures, like those promoted by Henry George in his economics classic Progress and Poverty, are those that raise, or are intended to raise, ways of enabling the poor to create wealth for themselves as a conduit of ending poverty forever. In modern times, various economists within the Georgism movement propose measures like the land value tax to enhance access to the natural world for all.
SocioeconomicsSocioeconomics (also known as social economics) is the social science that studies how economic activity affects and is shaped by social processes. In general it analyzes how modern societies progress, stagnate, or regress because of their local or regional economy, or the global economy. "Socioeconomics" is sometimes used as an umbrella term for various areas of inquiry. The term "social economics" may refer broadly to the "use of economics in the study of society".
AgroforestryAgroforestry refers to any of a broad range of land use practices where pasture or crops are integrated with trees and shrubs. This intentional combination of agriculture and forestry has multiple benefits, such as greatly enhanced yields from staple food crops, enhanced farmer livelihoods from income generation, increased biodiversity, improved soil structure and health, reduced erosion, and carbon sequestration. Trees in agroforestry systems can also produce wood, fruits, nuts, and other useful products with economic and practical value.
Polled livestockPolled livestock are livestock without horns in species which are normally horned. The term refers to both breeds and strains that are naturally polled through selective breeding and also to naturally horned animals that have been disbudded. Natural polling occurs in cattle, yaks, water buffalo, and goats, and in these animals it affects both sexes equally; in sheep, by contrast, both sexes may be horned, both polled, or only the females polled. The history of breeding polled livestock starts about 6000 years BC.
Parametric statisticsParametric statistics is a branch of statistics which assumes that sample data comes from a population that can be adequately modeled by a probability distribution that has a fixed set of parameters. Conversely a non-parametric model does not assume an explicit (finite-parametric) mathematical form for the distribution when modeling the data. However, it may make some assumptions about that distribution, such as continuity or symmetry. Most well-known statistical methods are parametric.
Malagasy UprisingThe Malagasy Uprising (Insurrection malgache; Tolom-bahoaka tamin' ny 1947) was a Malagasy nationalist rebellion against French colonial rule in Madagascar, lasting from March 1947 to February 1949. Starting in late 1945, Madagascar's first French National Assembly deputies, Joseph Raseta, Joseph Ravoahangy and Jacques Rabemananjara of the Mouvement démocratique de la rénovation malgache (MDRM) political party, led an effort to achieve independence for Madagascar through legal channels.
Sustainable fisheryA conventional idea of a sustainable fishery is that it is one that is harvested at a sustainable rate, where the fish population does not decline over time because of fishing practices. Sustainability in fisheries combines theoretical disciplines, such as the population dynamics of fisheries, with practical strategies, such as avoiding overfishing through techniques such as individual fishing quotas, curtailing destructive and illegal fishing practices by lobbying for appropriate law and policy, setting up protected areas, restoring collapsed fisheries, incorporating all externalities involved in harvesting marine ecosystems into fishery economics, educating stakeholders and the wider public, and developing independent certification programs.
