Cultivating trees and agricultural crops in intimate combination with one another is an ancient practice that farmers have used throughout the world. Agroforestry can be viewed as a societal response, primarily born out of a need to fulfill immediate basic human needs of food, fuel, fodder, shelter, protection etc. Effort to define Agroforestry began in the mid s and evolved rapidly as studies began on the diversity and scope of Agroforestry practices.

The development of sustainable agricultural systems in drylands is currently a crucial issue in the context of mitigating the outcomes of population growth under the conditions of climatic changes. The need to meet the growing demand for food, fodder, and fuel, together with the hazards due to climate change, requires cross-disciplinary studies of ways to increase livelihood while minimizing the impact on the environment. Practices of agroforestry systems, in which herbaceous species are intercropped between rows of woody species plantations, have been shown to mitigate several of the predicaments of climatic changes. Focusing on agroforestry in drylands, we address the question of how we can improve the performance of agroforestry systems in those areas. As vegetation in drylands tends to self-organize in various patterns, it seems essential to explore the various patterns that agroforestry systems tend to form and their impact on the performance of these systems in terms of biomass production, resilience to droughts, and water use efficiency. We use a two-soil-layers vegetation model to study the relationship between deep-rooted woody vegetation and shallow herbaceous vegetation, and explore how self-organization in different spatial patterns influences the performance of agroforestry systems. We focus on three generic classes of patterns, spots, gaps, and stripes, assess these patterns using common metrics for agroforestry systems, and examine their resilience to droughts.
In India, TAFS are present across different regions, having different practices. Agroforestry system are most predominant in the arid and semiarid.
T his report is an output from work-package 6 which addresses the third objective of the AGFORWARD project which is to evaluate innovative agroforestry designs and practices, at a field- and farm-scale.
Agroforestry is a land use management system in which trees or shrubs are grown around or among crops or pastureland. This diversification of the farming system initiates an agroecological succession, like that in natural ecosystems, and so starts a chain of events that enhance the functionality and sustainability of the farming system. 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. Agroforestry shares principles with intercropping but can also involve much more complex multi-strata agroforests containing hundreds of species. Agroforestry can also utilise nitrogen-fixing plants such as legumes to restore soil nitrogen fertility. The nitrogen-fixing plants can be planted either sequentially or simultaneously. According to Wojtkowski, the theoretical base for agroforestry lies in ecology,  or agroecology.
The land productivity in AF system by villagers is mostly low because of inappropriate AF practice. The objective of this research is to analyze the land management practice in Menoreh hills, Kulon Progo, Yogyakarta. The study was conducted in Giripurwo Village, Kulon Progo. Stratifed sampling with purposive sampling was used in this study. Total of twelve plots were determined in every AF levels. Studies conducted in every plot includes the species composition and soil fertillity.
In fact, it is common for farming systems to involve the integration of several reasonably discrete agroforestry practices, on different types of land.
Agroforestry is a land management approach that purposefully integrates the growing of trees with crops or livestock. Integration can involve:. They are specifically designed and managed for a planned result. Systems are a blend of agriculture, forestry and conservation. Management intensity will vary depending on the system design and planned results.
The practice of cultivating trees on farms alongside other agricultural production has a long history throughout the world. For thousands of years, people have been harvesting fruits and nuts from trees, making hay from the grass underneath or growing staple crops along the natural tree boundary that has defined their property. Trees bring diversity. Diversity of produce, diversity of landscape to support farming efforts and diversity of ecosystem services only trees can provide.
Jobs Details: Jobs: Adding agroforestry practices to a farm or ranching enterprise can strengthen the resilience of that economic enterprise to fluctuations and changes by diversifying its income. In turn, this resilience can help maintain and create jobs. Quality of Life: Agroforestry systems are beneficial to farms, ranches, and communities, where these
Фонтейн молча стоял. Сьюзан заглянула в распечатку через плечо Джаббы. - Выходит, нас атакует всего лишь первый набросок червя Танкадо. - Набросок или отшлифованный до блеска экземпляр, - проворчал Джабба, - но он дал нам под зад коленом. - Не верю, - возразила Сьюзан.
Она понимала, что это больше не имеет значения: Хейл и без того знал все, что можно было знать. Мне нужно доложить об этом Стратмору, - подумала она, - и как можно скорее. ГЛАВА 38 Хейл остановился в центре комнаты и пристально посмотрел на Сьюзан. - Что случилось, Сью. У тебя ужасный вид.
Пять секунд. Шесть секунд. - Утечка информации. - Никаких изменений.
Это можно было предвидеть, - подумала Сьюзан. -Ангел-хранитель. - И, полагаю, если с Танкадо что-нибудь случится, эта загадочная личность продаст ключ. - Хуже.
Стратмор отпустил створки двери, и тонюсенькая полоска света исчезла. Сьюзан смотрела, как фигура Стратмора растворяется во тьме шифровалки. ГЛАВА 63 Новообретенная веспа Дэвида Беккера преодолевала последние метры до Aeropuerto de Sevilla. Костяшки его пальцев, всю дорогу судорожно сжимавших руль, побелели. Часы показывали два часа с минутами по местному времени.
Это не вирус? - с надеждой в голосе воскликнул Бринкерхофф. Джабба презрительно хмыкнул. - У вирусов есть линии размножения, приятель.
Его жертва не приготовилась к отпору. Хотя, быть может, подумал Халохот, Беккер не видел, как он вошел в башню.
