ABSTRACT Global climate change tends to intensify water unavailability, especially in semi-arid regions, directly impacting agricultural production. Cowpea is one of the crops with great socio-economic importance Brazilian region, cultivated mainly under rainfed farming and considered moderately tolerant restriction. This species has physiological biochemical mechanisms adaptation these stress ...

Over the past 50 years, the scale and intensity of livestock farming have increased significantly. At the same time, Western societies have become more urbanised and fewer people have close relatives involved in farming. As a result, most citizens have little knowledge or direct experience of what farming entails. In addition, more people are expressing concerns over issues such as farm animal ...

This paper describes how the social capital of rice farmers of the Mekong Delta of Vietnam, as manifested in the tradition of collective farming practice, has changed. Collective rice farming persisted for decades, irrespective of critical events that challenged its continuation, due to two key factors: the high need for collective farming to ensure subsistence, and the availability of a closel...

We evaluated the ability of the WGEN model to generate long term weather series in situations where the actual historic weather data record is only 3–10 years long. The series generated were used to simulate yield of irrigated and rainfed chickpea. To do this, four 100-year samples of weather data were generated for Tabriz, Iran. The WGEN parameters used to generate data were obtained from dail...

We characterised the livestock-farming management strategies of multiple-job holders and identified which variables contributed most to the differentiation of these strategies. We hypothesised that they would mainly be differentiated by the contribution of the farming income to the total household income and the availability of the household members for farming. The multiple-job holding livesto...

introduction in dry areas, water is the limiting factor in improving agricultural production. saving the annual precipitation in the soil is very effective in dryland farming. the amount of rainfall that infiltrates the soil depends on the amount of soil permeability and runoff. the surface remains will be able to better permeable prevent runoff and raindrops and reduce erosion. in addition, ev...

Sustainable production requires balanced resource use and it is the management decisions at a household level that determine nutrient fluxes and the economic viability of enterprises. Traditionally, the agricultural systems of the mid-hills of Nepal have relied on the close integration of forestry, livestock husbandry and crop production but increasing population and other social changes are st...

H ow healthy are the earth's ecosystems? Will they continue to provide the food, water, shelter, and other necessities on which all life depends? These pressing questions have been receiving attention from two international collaborations: The Pilot Analysis of Global Ecosystems (PAGE) was completed in late 2000 and detailed in World Resources 2000–2001, the biennial report of the World Resourc...

Family farming, crop science and ‘globalisation’ together largely determine progress against poverty. Faster in 1960-90 than at any time in world history, such progress has slowed down. So have ‘land reform’ and science-based rises in small farmers’ staples food productivity, while aid to agriculture has fallen by over two-thirds and farm prices have been further forced down (and farm science d...

The growing demanding from consumers for healthier foods, produced using environmentally friendly farming practices has resulted in the rapid expansion of organic farming. There are numerous studies about the importance of organic farming but the majority of the results are sometimes contradictory, inconsistent and show no clear link between organic farming practices and enhancement of the nutr...
