Knowledge Systems in Agroforestry
Pacific Islands agroforestry has evolved into sustainable, diverse and productive a land use systems in many areas. We marvel at these systems, and the scientific world is trying to catch up with the traditional knowledge. At the same time, Pacific Islands farmers are abandoning their agroforestry systems in great numbers. It is mainly intensified agriculture for cash crop production that follo...
متن کاملPotential for Semiarid Community Type Differentiation
Abstract Community-level vegetation type differentiation is regarded as an important application of remote sensing in monitoring the health of semiarid environments and yet it has proved difficult to discriminate more than two or three community types with confidence when using coarse spatial resolution data from off-nadir scanning sensors such as the AVHRR, even when multi-temporal datasets ar...
متن کاملchannel estimation for mimo-ofdm systems
تخمین دقیق مشخصات کانال در سیستم های مخابراتی یک امر مهم محسوب می گردد. این امر به ویژه در کانال های بیسیم با خاصیت فرکانس گزینی و زمان گزینی شدید، چالش بزرگی است. مقالات متعدد پر از روش های مبتکرانه ای برای طراحی و آنالیز الگوریتم های تخمین کانال است که بیشتر آنها از روش های خاصی استفاده می کنند که یا دارای عملکرد خوب با پیچیدگی محاسباتی بالا هستند و یا با عملکرد نه چندان خوب پیچیدگی پایینی...
Minimal mechanisms for vegetation patterns in semiarid regions.
The minimal ecological requirements for the fomation of regular vegetation patterns in semiarid systems have been recently questioned. Against the general belief that a combination of facilitative and competitive interactions is necessary, recent theoretical studies suggest that, under broad conditions, non-local competition among plants alone may induce patterns. In this paper, we review resul...
متن کاملPersea schiedeana: A High Oil “Cinderella Species” Fruit with Potential for Tropical Agroforestry Systems
Persea schiedeana, a close relative of avocado (Persea americana), is an important part of agroforestry systems and diets in parts of Mesoamerica, particularly in the coffee growing areas of southeastern Mexico and Guatemala, where it is known as chinene, coyo, and yas. Little research attention has been given to this species, other than as a rootstock for avocado. Research carried out in six v...
