Sistemas agrícolas sostenibles para la seguridad alimentaria y nutricional

Los Objetivos de Desarrollo Sostenible de 2015 y el Decenio de las Naciones Unidas de Acción sobre la Nutrición suponen un llamamiento a todos los países para que acaben con el hambre y eviten la malnutrición en todas sus formas para 2030. Se trata de un gran desafío, en el que la agricultura y los sistemas alimentarios sostenibles juegan un papel fundamental. Sin embargo, la situación actual no es esperanzadora. El último informe sobre el El estado de la seguridad alimentaria y la nutrición en el mundo estima que el número de personas que padecen subalimentación crónica aumentó hasta los 815 millones en 2016 (frente a los 777 millones de 2015).

El Objetivo de Desarrollo Sostenible 2 establece además el objetivo mundial de duplicar la productividad agrícola y los ingresos de los pequeños productores en 2030. Al mismo tiempo, los sistemas de producción alimentaria deben ser sostenibles, reducir su impacto en los ecosistemas y ser resilientes ante los cambios medioambientales. Pero aquí también nos enfrentamos a retos importantes. Las conclusiones más recientes de modelos avanzados sobre las cosechas mundiales sugieren, por ejemplo, que los rendimientos globales del trigo, arroz, maíz y soja disminuirán sustancialmente con el aumento previsto de las temperaturas del planeta en los próximos años.

Los investigadores han comenzado sólo recientemente a abordar los vínculos entre la agricultura, seguridad alimentaria y nutrición, y el medio ambiente. En Asia, por ejemplo, el proyecto de Dietas sostenibles y saludables en India, dirigido por la Escuela de Higiene y Medicina Tropical de Londres, calculó por primera vez las emisiones de gases de efecto invernadero y la huella hídrica de la producción de alimentos en la India y calculó los cambios en los hábitos alimentarios necesarios para satisfacer la futura disponibilidad decreciente de agua subterránea. Se trata de algunos de los primeros trabajos de investigación en Asia meridional para cuantificar los vínculos entre la sostenibilidad medioambiental y la seguridad alimentaria y nutricional en un momento en el que, debido a la rápida urbanización, los cambios en las dietas y el aumento de la población, los sistemas alimentarios están sometidos a una presión creciente.

Otro ejemplo es el programa LANSA, que trabaja con comunidades locales en Afganistán, Bangladesh y Pakistán para identificar intervenciones en los sistemas agrícolas que aborden las deficiencias nutricionales de las comunidades, reduzcan los impactos medioambientales y también aumenten la resiliencia ante los factores de estrés ambiental. Son unos primeros pasos importantes para generar nuevas evidencias que ayuden a afrontar los desafíos actuales y futuros de los sistemas agrícolas.

Un estudio reciente ha revelado la existencia de numerosos estudios sobre el impacto de las intervenciones agrícolas en la nutrición en Asia meridional.  Sin embargo, es necesario seguir investigando para reducir el impacto de la agricultura en el medio ambiente y reforzar la resiliencia de los sistemas agrícolas locales ante los cambios medioambientales actuales y futuros: esto resultará fundamental para garantizar la seguridad alimentaria y una nutrición adecuada para toda la población.

En este contexto, la discusión pretende mejorar la comprensión de la investigación de LANSA sobre los sistemas agrícolas sostenibles para la seguridad nutricional. La discusión brinda también la oportunidad de compartir experiencias e investigaciones en curso en países de ingresos bajos y medianos sobre los vínculos entre agricultura, nutrición y medio ambiente.

Entre las preguntas para la discusión de tres semanas de duración, se incluyen éstas:

  1. ¿Está documentando el impacto del sistema agrícola en el medio ambiente?
  2. ¿Está investigando sobre el impacto de la agricultura y el medio ambiente en la seguridad alimentaria y nutricional?
  3. ¿Ha tenido alguna experiencia que vincule investigación y políticas en materia de sistemas agrícolas sostenibles para la nutrición?
  4. ¿Qué intervenciones considera necesarias para aumentar la resiliencia del sector agrícola ante los factores de estrés medioambiental, especialmente la de los pequeños campesinos?

La discusión se centra específicamente en los países de ingresos bajos y medianos, donde el impacto del estrés medioambiental en la seguridad alimentaria y nutricional será previsiblemente más intenso.

Esperamos que este tema y las preguntas le resulten estimulantes y le invitamos a compartir sus experiencias.

Dear Moderator

As to me sustainable farming system requires proper land use planning and cropping patter as mono cropping practice is the major cause for production decline due to decreased soil fertility, It also develops resistance to pests and diseases which is the main factor for production decline and food and nutrition insecurity

Inadequate understanding of food security in its full content also aggravates food and nutrition insecurity. Heavy focus on food availability while ignoring access issues and utilization where the importance of nutrition comes in.

Sustainable farming system also requires research, extension and farmers linkages to identify underlying causes of food and nutrition insecurity in order to design remedial measures. Considering the hidden hunger such as zinc defficiency, the need for biofortification, nutrition education and demonstration of vegetable meal preparation using school garden, farmers field days are essential

Sustainable farming system should have resource conserving technologies, address climate resilience and should be community supported. Climate change is perhaps the most serious environmental threat to the fight against hunger, malnutrition, disease and poverty, mainly through its impact on agricultural productivity.

Agriculture is a major provider of environmental services and it plays an important role in sequestering carbon, managing watersheds and preserving biodiversity. Agriculture is also a major consumer of natural resource, contributing to underground water depletion, agrochemical pollution, soil exhaustion and global climate change. Agricultural extension personnel have to take a lead role in this respect in promoting sustainable farming system.

Consumers are now more concerned about obtaining safe food.. Food safety involves a much broader range of public health issues related to food production. Food safety concerns begin from on farm production of food commodities. It is the key entry point for the introduction of management practices that allow minimising potential contamination with excessive residues of harmful chemicals in food and water. GAP is one such preventive food safety approach which ensures that food is produced concerning about health and environment. Nutrition and food security must be considered in developing food safety guidelines and standards.

The International Human Rights framework which includes instruments that address the right to food, water and health as well as human rights is to be considered. Food sovereignty is critical because our current food and farming system is thoroughly broken. Food sovereignty is essential to guarantee the human rights of communities to choose when and how their food is produced and what food they consume. This is more relevant in the present context of controversy related to type of food being consumed

Q. What interventions do you think are needed to increase the agriculture sector resilience to environmental stressors, especially among smallholder farmers?

Low or middle income countries are highly suffering from various environmental hazards impacting to almost all the people of the country. But, especially the smallholder farmers known as small farmers who are living in a poor condition even in the form of tenants are vulnerable. They have to suffer from different environmental threats like untimely and torrential rain, drought, flood, landslides, avalanches, earthquake, and epidemics etc. They are lacking of food to meet their hunger every day. Consequently, the under 5 children and the lactating and pregnant mothers will highly be affected due to deficiencies of nutrients resulting to malnutrition. Further it will be more serious in the case of under two children who could be retarded physically as well as mentally. Thus the environmental hazards are suppressing to the countries towards low level of food and nutrition security.

Considering the scenario of agriculture sector resilience to environmental stress some remedies is recommended focusing to the small farmers as follows:

  1. Orientation about the improved farming techniques depending upon the food crop that they are cultivating. Use of compost, as one of the techniques, especially the vermin compost is highly recommended for organic farming that is more lucrative and nutritious with high demand in the market.
  2. Facilitation and orientation to promote production and consumption of indigenous foods depending upon the soil and climatic condition of the locality.
  3. Provided the inputs like seeds, medicines, and other machineries for farming.
  4. Prefer to intensive farming rather than extensive to get better productions from limited area of the land.
  5. Prefer to use traditional tools / weapons in sloping area to save the land from sweeping way and landslides in sloping area. 
  6. Increase awareness of crop diversification with potentialities.
  7. Apply the policy of early warning system of disasters and natural calamities to the farmers.
  8. Prefer to other types of farming like livestock and birds raising, aquaculture, cash crops like cardamom, ginger and tea plantation.
  9. Provision of rented in of barren land to the small land holders should they want to cultivate on it.
  10.  Introduce the livelihood programs for the farmers to reduce dependency from farming occupation.

Dear Friends,

Good Day

We were looking for the answer to question of "What interventions do you think are needed to increase the agriculture sector resilience to environmental stressors, especially among smallholder farmers?" our experience indicates following points as important.

1. More or less policies of present day agriculture department are restrictive for diversity, mainly they focus on limited crops and varieties. Agriculture officers follows conventional extension programs which are of givers mode, not respecting farmers knowledge.

2. As for as small and marginal farmers are going through dilemma of traditional versus market controlled, nutrition oriented vis-a-vis cash generating. VAAGDHARA believes some where farmers need dual approach of nutrition sensitive farming with market approach, taking benefit of community awareness about the fresh and chemical free food.

3. There is need for strengthening a network of farmers led institutional platforms which will have interactive farming, research, education, and marketing. Unfortunately present day agriculture promotion institutions are in two parallel streams one is scientific & government institutions another is administrative department of agriculture management, which do not have concurrence  at many front.

4.In this direction we have been using approach of creating local level farmers network, we are also moving towards traditional institution of "Gram Chopal" to take this agenda forward. In this direction we would like to collaborate with other agencies and groups who are active with this approach.

5.Improvement in farm diversity through tools like "What we produce - What we consume" and focusing on concept of reducing "Food Mileage" could be really helpful in this direction

Thanks

Everyone is familiar with the changing climate of the world. Countries are taking initiatives to minimize the effect of climate change on food security. Being a plant pathologist, we may incorporate biological agents to manage plant diseases. Fungicides and pesticides have impact on farming system as well as on environment. Moreover the fungicides give the results very quick. No doubt they are polluting the environment as well as super races of pathogens evolve. Biological agents such as Trichoderma spp, Coniothyrum spp as well as other in various formulations must be provided by the respective countries to the farmers in cheap price. The farmers will slowly become habitual to spray these biological agents on their plants. In this way thousands of beneficial species which are stabilizing the ecosystem can be saved from the toxicity of the chemicals. In the underneath of plants, we must create more completions between pathogen and biological agents so that the pathogens will not find time to infect plants as a result the yield will be boost up and will feed the growing populations. I am currently working on biological agents and find that biological agents perform well as compared to toxic synthetic fungicides. I think the environment become safer with the biological agents and if the environment would be safe, certainly the food and nutrition will be more secured. I want to explore the microbes further to gain sustainable agricultural systems. 

Dear all,

Q2. Are you conducting any research on the impact of agriculture and environment on food and nutrition security?

Yes I’m working on linking food security and crop diversification across districts of Sindh. According to my findings though yield is decreasing here but availability is not the issue. Issues lie in the accessibility and adsorption of food and as food inflation and general inflation is rampant as well as no standardization or food protocol about the food quality or preparation is implemented. Moreover, absence of drinking water and sanitation facilities making the conditions worse which not only results in stunting or malnutrition even deaths and losses to the livestock and productivity.

Climate change is a biggest threat as Sindh is mostly arid and dependent on rain water. Higher temperature and low moisturize with delayed or no rain plays havoc for the people depending on crop production, livestock rearing or fishing.

One of the areas that is often neglected in designing agricultural policies and strategies relates to the environmental and natural resource sustainability considerations. However, to achieve this it is important ot understand what factors contribute the policy processes and how one can steer the process in the right direction. Our recent paper in Nigeria provides some insights. I attach the link here for the participants to access this. Comments are welcome.

Thanks Mr. Md. Kamrul Islam and Dr. Kuruppacharil for your inputs. There are few changes occurred during recent years on the homestead gardening. BRAC has introduced this concept of homestead gardening in a bit different way. We called it Nutri-garden. Nutri-garden is the yearlong comprehensive package of growing nutrient dense and naturally fortified fruits and vegetables by engaging rural women to enhance diet diversification and improve nutritional status in the household’s. Nutri-garden intervention offers a great potential for alleviating malnutrition and improving household food security and diversity. Nutri-gardens are established in homestead, gher/pond dyke areas and other fallow and unutilized land by which proper utilization of fallow land is being ensured and crop area is being increased. Nutri-gardens are an important source of income for rural households from sales of the garden products. Women are playing a vital role in providing better nutrition for their family by producing their own nutritious foods in Nutri-gardens.

The objectives of Nutri-garden interventions of BRAC are: 1. To improve nutritional status of households through consumption of diversified food. 2. Year round availability of at least five nutrient enriched fruits and vegetables in the households. 3. Enhance household income by engaging rural women and 4. Raising awareness for producing safe food.

Several nutrient enriched fruits and vegetables are being cultivated in Nutri-garden such as Red amaranth, Spinach, Pointed gourd, Okra, Tomato, Brinjal, Aroid, Sweet gourd, Bottle gourd, White gourd, Sponge gourd, Snake gourd, Cucumber, Long yard bean, Country bean, Carrot, Orange flashed sweet potato, Drumstick, Papaya, Guava, Banana etc.

An outcome study was conducted by BRAC about Nutri-garden from which it was found that- 5 to 14 crops was available in each Nutri-garden and about 8 crops was found in 30% Nutri-garden. Annual production is 2,130 kg/Nutri-garden/year and annual income is BDT 39,902/Nutri-garden/year (80 BDT = 1 US$).

A success story on Nutri-garden can be found following the link below: Nutri-gardening: Hosne Ara’s endeavor to success

Problem to be addressed :

Marshland area of Madaripur and Gopalgonj Districts are known as very low crop ( paddy ) yielding areas and frequent crop failure is the natural phenomenon in these areas as usually these areas are steadily being swamped by locked water body almost every time of the year.  Only 5 months in a year from December to May lands come out of water when the poor farmers cultivate to get one time yearly paddy especially known as BORO Paddy and for the conventional cultivation practice and lack of proper modern agricultural know-how, technique and knowledge, the per acre paddy yielding is much less than 1 ton which is one of the lowest level in Bangladesh which is the main cause of poverty and misery of people these areas. On the other hand, if proper agriculture technology and applicable appropriate cultivation methods are used in cultivation and if people are fully conversant to modern way of crop cultivation, the yearly paddy yielding can easily be multiplied to more than  2 tons to 2.5 tons in several folds, which not only alleviate their poverty but will ensure their sustainable growth in  socio-economic status.  The main root causes for this problem are ignorance of local people to modern agricultural technologies, their traditional and conventional attachments, beliefs and approaches for paddy cultivation, lack of facilities to effective technology transfer to these farmers & cultivators because of the isolation and poor communication to reach the target areas, absent of government & NGOs initiatives to solve this problem & poor facilities to make people conversant to modern agricultural technologies applicable to these areas. As a result, it is often found that when people face severe crop shortage or crop failures, ultimately they pledge their arable land to affluent ones and quickly become landless and marginal  farmers and transform into agriculture labor. In this way when work for agro-based labor become scarce in non-agro-period, they have to starve and ultimately migrate to urban slums for low skilled jobs and pass most inhuman and miserable lives. Thus a farmer family from this area become uprooted very quickly and go under poverty line and become enormous load to community and country as well. So, look into their problem is of urgent  need on humanitarian and socio-economic perspective.
