In general, farmers benefit from having an increase in crop yield and from being able to grow a variety of crops throughout the year.

Research efforts are aimed not only at increasing the productivity of cropping systems but also at ensuring that agriculture is sustainable.

Yields of all major crops have been rising dramatically in recent decades, owing to higher yielding crop varieties and farmers greater use of fertilizer, pesticides, and irrigation.

In some African countries, for example, yields could decline by as much as 50 by 2020.

Africa needs to boost its yields, and that means enabling farmers to use modern crops, fertilizers, and pesticides.

Investments in agriculture, such as subsidized fertilizers and seeds, increases food harvest and reduces food prices.

35. The manufacturing sector consists of small scale production units, including electronic assembly, textile, furniture, leather and agro processing plants.

But many poor countries can grow more food themselves, because their farmers are producing far below what is technologically possible.

Without risk management, poor people will not experiment with new crops or more productive methods, because any mistake could be disastrous.

Improving carbon productivity requires improving land productivity.

The techniques are known, but Africa s farmers are too poor to get started. With increased help to African farmers to grow more food (as opposed to shipping food aid from the US), it would be possible to double or even triple crop yields.

The Productivity of Trust

How can agricultural yields be raised? What is the best way to develop aquaculture?

Boosting yields of locally grown staple foods (rather than cash crops) would increase self sufficiency and strengthen resilience when international food prices are high.

Low productivity of licit agricultural crops, insufficient infrastructure and lack of access to technology, credits and markets all inhibit the generation of licit income beyond subsistence levels.

Intercropping. Intercropping really increases income.

Some Parties also identified as options for limiting emissions from agriculture the promotion of land use planning, encouragement of integrated farming, promotion of low tillage or no tillage agriculture, banning of sugar cane burning prior to harvest, post harvest management (including the avoidance of burning of farm waste), ploughing of vegetative waste into the soil, management and administration of grasslands and changes in the use and handling of crop residues.

That means greater investment in crop research to produce more robust and higher yielding varieties, as well as making more irrigation, pesticides, and fertilizer available.

Their poverty causes low farm productivity, and low farm productivity reinforces their poverty.

The Best, Brightest, and Least Productive?

The basis for this claim was a single report from the World Wildlife Fund that itself cited only one study, which didn t even look at climate change, but rather at the impact of human activities like logging and burning.

Moreover, CO2 acts as a fertilizer, and its increase has probably raised global yields more than 3 over the past 30 years.

Harvest contaminated tobacco.

Harvested (crude value)

(a) Crop production

The crop prices used by Iran in calculating the value of lost crops are not appropriate for estimating the value of crops that were not, in fact, produced.

In an agricultural society, the difference between the richest and the poorest, the most productive and the least productive, was five to one. Why?

As can be seen, investment productivity in Albania is significantly lower than that of the LDCs as a group.

In an agricultural society, the difference between the richest and the poorest, the most productive and the least productive, was five to one.

The number and types of impacts in this sector included productivity yield of crops, effects on soil moisture, and incidence of pests and spread of infectious diseases, as well as effects on the length of the growing season, carbon fertilization and productivity of pastures and livestock.

The transition from low to high productivity and to cleaner production that is environmentally sustainable is especially difficult.

Iran estimates the alleged reduction in crop quality by comparing crop prices in the Southern Provinces in 1991 with national crop prices.

Similarly, Ethiopia has made strides towards shifting agricultural policies and investing more in productivity improvements for small farmers, with increased spending helping to boost crop yields over the past several years.

(b) Reduced drop yields

But we saved the crops!

Some 90 per cent of the population depends on subsistence farming, and three consecutive years of drought, the spread of crop pests and decreased land productivity have put some 100,000 households at risk of food insecurity.

In terms of crop management, the options include the development and introduction of tolerant resistant crops, pest and soil studies, better cropping or farming systems, improved irrigation techniques and crop rotation, as well as changes in the timing of planting of crops.

It had therefore been necessary to increase the productivity of resources.

The second priority has been to enhance private sector productivity.

Light somewhat reduced agricultural productivity

Moderate greatly reduced agricultural productivity

Wasteful abusive and focused on labor productivity.

Not only would this reduce hunger by increasing food production and lowering food prices it would also protect biodiversity, because higher crop productivity would mean less deforestation.
