Means of conserving tropical rainforests 6 Improvement of agricultural methods and productivity 6 Improvement of agricultural methods and productivity Improvement of agricultural methods and productivity to reduce the need to cut down additional forest land.

Tropical forests cannot be maintained unless agricultural productivity is greatly improved. However, to feed the projected population of the midst century even at present levels, not to mention a level approaching that of developed countries, agricultural efficiencies would have to be far greater than is currently the case in most countries.

We need increases in agricultural productivity of between 1. The average annual growth rate of agricultural productivity in Sub-Saharan Africa between and was 2. To provide levels of nutrition equivalent to more developed countries, still higher production growth rates will be necessary.

This can occur only if technologies are greatly improved and substantial financial support is provided by wealthier countries. Without such development, conservation strategies are doomed merely by arithmetic.

It is argued that, with proper techniques, including irrigation, sustainable agriculture can be established on former rainforest soils soybeans in the Brazilian Amazon, for example.

Of course, sugar has been raised in the Caribbean and rice has been successfully cropped for thousands of years in Southeast Asia on tropical forest soils.

This type of agriculture is possible where soils are fertile, as in the regions of Indonesia which have rich volcanic soils. But elsewhere, as in East Java, only the most marginal agriculture raising tapioca and other low-nutrient tubers is possible, and these areas are extremely poor.

Some nonvolcanic rainforest areas lie on reasonably fertile soils especially in deltas and can sometimes sustain appropriate crops.

Intensive crop farming - Wikipedia

Recently, archeologists have discovered the remains of ancient agricultural systems in the Beni region of Bolivia. These artefacts lie in seasonally-flooded savannas which have long been thought to be useful only for cattle ranching.

However, the many raised agricultural fields, fish ponds and other agricultural constructions indicate that these areas have been productive in the past.

Recently, the construction of similar raised fields in savanna areas in Bolivia has permitted the cultivation of tubers, maize, and manioc Mann, If more of these areas could be converted to productive agriculture, they could provide a source of land as an alternative to rainforest removal.

Often, however, governments encourage and indeed, almost coerce the development of unsuitable agricultural products, although they should not attempt to introduce non-native species and unsuitable crops or domestic animals into forest areas.

For example, the Peruvian government has aggressively promoted the introduction of rice cultivation and water buffalo husbandry into many areas of the Amazon rainforest. In most places, rice is a most unsuitable cultivar, and water buffalo have caused serious erosion of riverbanks and destruction of vegetation.

To improve agricultural productivity, a number of things must be accomplished: Reduction of the present rate of degradation and loss of productive farmland due to erosion, salinization, waterlogging, and nutrient depletion: Technologies for these purposes are available, but are little used because of the expense.

However, many non-technological methods have been used for years by farmers contour plowing, abandonment of marginal agricultural lands, planting of wind barriers, fallowing. Erosion can be prevented by the careful selection of appropriate crops, keeping ground cover on the soil, and contour plowing.

Drip irrigation and other efficient delivery systems, better water distribution systems, improved control systems, and raising crops suited to the climate and soil will aid in this endeavor.modern wheat varieties in s by Dr Bourlaugh from Norin 10 cultivars of wheat grown in Japan It has potential to increase crop production Technologies for increased Crop yield Pramod.

Crop yield[edit] Using the techniques of modern biotechnology, one or two genes (Smartstax from Monsanto in collaboration with Dow AgroSciences will use eight, starting in ) may be transferred to a highly developed crop variety to impart a new character that would increase its yield.[26].
