There is increasing interest in rural development circles in promoting alternative livelihoods opportunities for pastoral and agro-pastoral livelihoods. However, there is very little empirical evidence that effectively evaluates the impact of the existing approaches. As pastoral and agro-pastoral production conditions change, due to factors such as increasing competition over natural resources ...

agro-ecological zoning is one of the effective tools for assining land to suitable land use.the study areawith16618ha islocatedin abyek area inqazvin province. in totally 43 agro- ecoloical zones were distinguished by combining maps of isohyet, isotherm, length of growing periodand agro-edaphic zones. based on above information a land suitability was produced for the study area and prediction o...

Climate is one of the most important factors that influence the quality and quantity of crops. Understanding the natural features of any region, especially about the climate, can play a major role in making plans and land use planning. Sugar beet, is one of the major industrial plants, that in addition to producing one of the most fundamental basic needs of society, namely sugar, it can have ot...

Understanding drivers of population fluctuation, especially for agricultural pests, is central to the provision of agro-ecosystem services. Here, we examine the role of endogenous density dependence and exogenous factors of climate and human activity in regulating the 37-year population dynamics of an important agricultural insect pest, the cotton bollworm (Helicoverpa armigera), in North China...

Research is needed by global change scientists on how global vegetation biomes respond to ongoing climate warming. To address this issue, we selected study sites with significant climate warming for diverse vegetation biomes, and used global gridded temperature and remote sensing data over the past 32 years (1982–2013). The results suggested that climate warming in areas above approximately 60◦...

A new unsupervised algorithm, called CLimate and rEmote sensing Association patterns Miner, for mining association patterns on heterogeneous time series from climate and remote sensing data, integrated in a remote sensing information system is developed to improve the monitoring of sugar cane fields. The system, called RemoteAgri, consists of a large database of climate data and low-resolution ...

Symposia on topics relating science and technology to development issues continue to be organized by the Interciencia Association (IA), the inter-American federation of national scientific organizations which AAAS helped *to found in 1975. These events, 14 of which have been sponsored since 1976, have taken place in all eight countries which comprise the Interciencia group (Brazil, Canada, Colo...

The global push towards a more biomass-based energy sector is ramping up efforts to adopt regionally appropriate high-yielding crops. As potential bioenergy crops are being moved around the world an assessment of the climatic suitability would be a prudent first step in identifying suitable areas of productivity and risk. Additionally, this assessment also provides a necessary step in evaluatin...

The livestock sector serves as a foremost source of revenue for rural people, particularly in many developing countries. Among the livestock species, sheep and goats are the main source of livelihood for rural people in Ethiopia; they can quickly multiply, resilient and are easily convertible to cash to meet financial needs of the rural producers. The multiple contributions of sheep and goat an...
