Are genetically modified (GM) crops a commercial risk for Africa?
What risks might Africa face if it decided to plant genetically modified (GM) agricultural crops? A rough calculation based on current export profiles for one sampling of eastern and southern African countries suggests that the commercial export risks incurred outside of Africa would be quite small. Most of Africa's exports of goods that might be considered GM currently go to other African ...

Factors influencing the conversion to organic farming in Norway
Determinants of the decision to convert to organic farming methods are examined by applying bivariate analyses and a multinomial logit model to a survey of 1018 Norwegian crop and dairy farmers. The results show that 4% of the conventional respondents plan to convert by 2009, which may imply that the national goal of 10% organically managed area will not be achieved. The analysis indicates that ...

Assessing the prediction capacity of an agricultural supply positive mathematical programming model
In this paper, the calibration and prediction capacity of a supply response positive mathematical programming model (PMP) for the Alentejo region are evaluated. The model is calibrated with prices and agricultural subsidies of the base year (2000), using the specification rules of the cost function standard, Paris standard, average cost and exogenous elasticities. Then, the model is utilised for ...

Managing agricultural biotechnology for sustainable development: the case of semi-arid India
Managing agricultural biotechnology for sustainable development demands more than research and intellectual property rights policies. Economic and regulatory institutions conducive to application of intrinsically sustainable technologies are also required. From an interdisciplinary development research perspective, it is argued that sustainability of Indian agriculture and food crop production ...

So what is the role of commodity programs? Can they even be justified?
No matter what our area of daily activity, it is natural and even necessary that we myopically focus on the problems and issues of the day. But it is also important to step back once in a while to consider how the situations of today fit into a longer-term context. Along that line, we are in the midst of a series of columns that goes beyond the agricultural issues and policy motivations of ...

Simulating the Effect of Climate Change on Agriculture
Increased atmospheric CO2 levels and climate change are believed to contribute to extreme weather conditions, which is a major concern for many. And beyond extreme events, global warming is also predicted to affect agriculture.1,2While climate change is expected to affect agriculture and reduce crop yields, the complete effects of climate change on agriculture and the resultant human food ...

Agricultural research policy framework for improved livelihoods security in crop-livestock production systems
Concerns for sustainable development and poverty alleviation are forcing public agricultural research systems to focus on improving livelihoods security. Crop-livestock production systems are central to the livelihood security of the rural poor in India and some other countries of the tropics. With increasing population, urbanisation and incomes, massive increases are foreseen in demands for ...

Convert Agriculture Waste Into Energy
India is mainly an agricultural county and is also the largest contributors in the GDP of the country. Agriculture provides employment to a huge population of the rural India. This was not the case suddenly post-independence in India. Various steps were taken to make India as a reliable agricultural country. Steps such as green revolution were taken in several five years plan. This has made India ...

Economic partnership agreements, common external tariff and prospects for staple food items in Nigeria
This paper looks into the potential impacts of the proposed Economic Partnership Agreement (EPA) between African, Caribbean and Pacific countries and the European Union (EU) on agriculture and food production in Nigeria. Using a partial equilibrium analysis, it assesses possible changes in production arising from the implementation of a Common External Tariff (CET) and/or EPA on three crops ...

Valuation of nitrogen retention as an ecosystem service on a catchment scale
An ecosystem service approach was used to study the water purification service exemplified by impacts of land management scenarios. Nitrogen retention was calculated in two agricultural catchments by the dynamic Integrated Nutrients in Catchments (INCA)-N model. The monetary valuation was based on purification efficiency of artificial wetlands. The set of scenarios were based on existing ...

Integrating ecosystem services into crop protection and pest management: Case study with the soil fumigant 1,3‐dichloropropene and its use in tomato production in Italy
Ecosystems provide the conditions for producing food, regulating water, and providing wildlife habitats; these, among others, are known as ecosystem services (ESs). Food production is both economically and culturally important to southern European farmers, particularly in Italy where farmers grow flavorsome tomatoes with passion and pride. Growers rely on pesticides for crop protection, the ...

Farmonaut For Crop Area and Yield Estimation
INTRODUCTION: CROP AREA ESTIMATION The two components of agricultural production estimation are crop area and yield estimation. In order to estimate yield, Producers generally measure the amount of a particular crop harvested in a sample area to estimate crop yield. The harvested crop is then weighed, and the entire crop production of the area is approximated from the sample. A method for ...

Asia–Pacific Analysis: Plan for growth in biotech crops
South-East Asian nations should follow the Philippines down the path to biotech crops for food security, argues Crispin Maslog. Since biotechnology-derived crops were introduced in 1996, they have been adopted at an unprecedented rate, according to the 2011 annual report of the International Service for the Acquisition of Agri-biotech Applications (ISAAA) released earlier this year. [1] There ...

Simulating Agricultural Climate Change Scenarios using Controlled Growth Chambers
Extreme weather, believed to result from climate change and increased atmospheric CO2 levels, is a concern for many. And beyond extreme events, global warming is also expected to impact agriculture.1,2 Although it is expected that climate change will significantly affect agriculture and cause decreases in crop yields, the full effects of climate change on agriculture and human food supplies are ...

How farm policy used to work
In the period between the 1930s and 1992, farm bills generally instituted compensation policies that took the form of price supports. These policies were designed to manage the surplus production that resulted from centuries of developmental policies while allowing U.S. farmers the chance, with hard work and good management skills, to provide their family with a livelihood. Compensation policies ...

Pesticides in the European Union
There has been a sharply falling trend in the total volume of sales of agricultural pesticides in the EU between 1991 and 1995. But this was reversed in 1996. From 1991-1995, EU sales of pesticides, measured by weight of active ingredients (ai), fell by 13%. They then rose by 6% between 1995 and 1996 to stand at 299,826 tonnes ai. But this still put them nearly 8% below the 1991 figure. The use ...
