Tanveer,A.; Khaliq,A.; Javaid,M.M.; Chaudhry,M.N.; Awan,I..

The genus Euphorbia comprises about 2000 species ranging from annuals to trees, including C3, C4, and CAM species. Euphorbia species widely studied in agriculture includes E. antiquorum, E. carollata, E. dentata, E. dracunculoides, E. esula, E. geniculata, E. granulata, E. helioscopia, E. heterophylla, E. hierosolymitana, E. hirta, E. maculata, E. microphylla, E. nerifolia, E. piluifera, E. pulcherrima, E. royleana, E. supine, and E. thiamifolia. These species have been reported mainly in field crops/vegetables, orchards, pastures, and rangelands. Euphorbia plants may present allelopathic effect over desirable cereals, pulses, oilseeds, vegetables, forage plants, and nitrifying bacteria, posing a serious threat to livestock production on open range lands...

Adoption of Maize Production Technologies in the Coastal Lowlands of Kenya

Wekesa, E.; Mwangi, Wilfred; Verkuijl, Hugo; Danda, Milton Kengo; De Groote, Hugo.

Maize is the major food crop grown in the coastal region of Kenya and constitutes a major component of the diet of the population in the region. However, average yields are far below the potential for the region and low production levels create serious food deficits. Over the years, new technologies have been introduced but adoption has remained low, especially for fertilizer. This paper examined current maize-farming practices and technological and socioeconomic factors that influenced adoption in the Kilifi and Kwale Districts of the Coast Province, that together account for half of maize production in the region. The study found low adoption levels for improved maize varieties and technology, especially fertilizer, among farmers in the area. Farmers...

Agricultural Land Tenure and Carbon Offsets

Claassen, Roger; Morehart, Mitchell J..

Agricultural Land Tenure and Carbon Offsets examines the potential role that land ownership might play in determining the agricultural sector’s involvement in carbon sequestration programs. By estimating the carbon sequestration potential of agricultural producers who own most of the land they operate, this report finds that land ownership should not be a constraining factor in agriculture’s ability to provide carbon offsets.

Land Allocation Effects of the Global Ethanol Surge: Predictions from the International FAPRI Model

Fabiosa, Jacinto F.; Beghin, John C.; Dong, Fengxia; Elobeid, Amani E.; Tokgoz, Simla; Yu, Tun-Hsiang (Edward).

We quantify the emergence of biofuel markets and its impact on U.S. and world agriculture for the coming decade using the multi-market, multi-commodity international FAPRI (Food and Agricultural Policy Research Institute) model. The model incorporates the trade-offs between biofuel, feed, and food production and consumption and international feedback effects of the emergence through world commodity prices and trade. We examine land allocation by type of crop, and pasture use for countries growing feedstock for ethanol (corn, sorghum, wheat, sugarcane, and other grains) and major crops competing with feedstock for land resources such as oilseeds. We shock the model with exogenous changes in ethanol demand, first in the United States, then in Brazil, China,...

Crop switching as a strategy for adapting to climate change

Kurukulasuriya, Pradeep; Mendelsohn, Robert.

This paper examines the impact of climate change on primary crops grown in Africa. An innovative approach is presented that bridges the gap between agro-economic and traditional Ricardian models. We label it a ‘structural Ricardian model’. It first captures the type of crop a farmer will select and then examines the conditional net revenue of that crop. The model is estimated using a sample of over 5000 farmers across 11 countries in Africa. The analysis finds that farmers shift the crops they plant to match the climate they face. Studies that fail to account for crop switching will overestimate the damages from climate change and underestimate the benefits.

PESTICIDE TAX, CROPPING PATTERNS, AND WATER QUALITY IN SOUTH CENTRAL TEXAS

Shumway, C. Richard; Chesser, Rayanne R..

The impact of an ad valorem pesticide tax on cropping patterns and pesticide use was examined in the South Central Texas Crop Reporting District. Output supply equations were econometrically estimated and used in the simulation. A 25 percent tax on pesticide was estimated to have major impacts on cropping patterns and on pesticide use. Assuming other input and output prices were unaffected, the supply of one important crop would fall by more than half. Demand for some of the highly soluble and persistent pesticides, which present the greatest threat to groundwater quality, would also decrease substantially (some as much as 50 percent).

Projeções do Agronegócio no Brasil – 2007/08 a 2017/18

Gasques, Jose Garcia; Bastos, Eliana Teles; Dossa, Derli; Silva, Lucille Freire Da; Paula, Ricardo De Almeida.

Este trabalho é uma atualização resumida do trabalho de projeções do agronegócio Mundial e Brasil que tem sido feita pelo Ministério da Agricultura, Pecuária e Abastecimento (MAPA) nestes últimos quatro anos. O período do estudo é 2007/2008 a 2017/2018. O trabalho de projeções tem por objetivo fornecer subsídios aos formuladores de políticas públicas quanto as principais tendências de produtos agropecuários, para a tomada de decisão e para o delineamento de linhas de atuação, embasando e fortalecendo os instrumentos de política agrícola nacionais. Para o setor privado a importância do trabalho se dá no sentido de indicar como o governo visualiza o futuro das principais cadeias do agronegócio, além de oferecer os resultados das projeções a partir dos quais...

Successful Community-Based Seed Production Strategies

Hutchings, Timothy R..

This study presents a method of simulating longer-term cash flows that reflect the cumulative effects of variation in seasons, prices, enterprise sequences and mixes and other management decisions. It can be used to develop full risk profiles on a whole-farm or individual-component enterprise basis for most dryland farms in southern Australia, at gross margin, profit or cash flow levels. This analysis concentrates on the cash flow implications of these various scenarios because cash flow is the indicator which includes all costs, and therefore demonstrates affordability and the long-term viability of the farm business entity. This study shows that the role of sheep in the mixed farming enterprise in south-eastern Australia is to reduce the exposure of the...

Productivity Growth and Convergence in Crop, Ruminant and Non-Ruminant Production: Measurement and Forecasts

Designed to address the issues that limit the access of small-scale farmers in sub-Saharan Africa to quality, affordable seed of the crops on which they depend for food security and livelihoods, this collection of articles describes successful principles for and experiences in community-based seed production. Among other things, the manuscripts analyze current seed production systems and models; propose ways to design successful community-based seed production schemes; describe proper seed production practices for selected cereals, vegetatively propagated plants, and other crops; and outline basic business practices for seed producers.

Ludena, Carlos E.; Hertel, Thomas W.; Preckel, Paul V.; Foster, Kenneth A.; Nin Pratt, Alejandro.

There is considerable interest in projections of future productivity growth in agriculture. Whether one is interested in the outlook for global commodity markets, future patterns of international trade, or the interactions between land use, deforestation and ecological diversity, the rate of productivity growth in agriculture is an essential input. Yet solid projections for this variable have proven elusive particularly on a global basis. This is due, in no small part, to the difficulty in measuring historical productivity growth. The purpose of this paper is to report the latest time series evidence on total factor productivity growth for crops, ruminants and non-ruminant livestock, on a global basis. We then follow with tests for convergence amongst...

Fleming, Euan M.; Villano, Renato A.; Fleming, Pauline.

Scope economies can be used in studies of farming systems to provide a measure of synergies between different farm enterprises and between activities within farm enterprises. In this paper, they are reported for farms in a benchmarking group in the Wheat-Sheep Zone in New South Wales, Australia, by estimating a stochastic input distance function and calculating an ‘economies of scope parameter’. Evidence is presented of scope economies between sheep and beef enterprises, sheep and crop enterprises, and beef and crop enterprises.
